Organizational Focus and Goals Essay

The purpose of the Management Challenges and Concerns Report is to indicate the responsibilities of management and how to meet or exceed company goals. Some of the responsibilities of human resource management consist of providing employees with information on the company’s vision, goal, HIPPA privacy rights, and mission statement. In addition, employees receive information on safety rules, insurance benefits, compensation, employee relations, training, and orientation classes. These responsibilities are significant and require patience along with strong leaders. Human Resource Managers has to acquire a bachelor’s or master’s degree in management, management classes, and pass test. Also human resource management requires the following characteristics: positive, consistent, prompt, role model, team player, and strong leaders. Performance Management consist of appraisal system, driving appraisal process, evaluating employee performance, and performance counseling (Brewster & Soderstrom, 1994). Internal issues pertaining to employees consist of productivity, abiding by company rules, safety, passing training classes, and positive work ethics. Human Resource Management has rules and regulations in the company handbook to ensure consistency at work. These rules and regulations set the pace for a productive and professional workplace environment for employees and management. Internal issues may arise; however it is human resources job to insure the policies put in place are being effective and followed. Staying Connected with New Talent Another example and challenge that we seem to face being able to stay connected with the and young talent, numerous businesses have increased a presence in social media platforms. Many companies have established Facebook and LinkedIn accounts to connect with prospective employees; few of them have even created specific accounts to attract their young employees to  share their working experiences and how satisfied they are with their employers. For example they can share information about its internship programs, how the CEO’s mission and vision is viewed and keep informed on daily bulletins. Half of the population in the United States is younger than 30 years old and Human Resources managers need to be very cognizant of what the younger people want and need from a career in the workplace and how to attract these talent. Enticing Technical Talent and Generating Opportunities Although the country’s unemployed rate is still at 9.1%, the need for Information Technology work force like Electronic Engineers remains a shortage at many businesses. To appeal higher technical talent, various Human Resource recruiters are going back to school to search for these talents. It’s a challenge, but there’s resources out there that can be found and assist in bringing talent to an organization.

Patient access, data mining and PHI Essay Example | Topics and Well Written Essays - 250 words

Patient access, data mining and PHI - Essay Example However, the primary concern about the system is its ability to support use by people at different levels including patients without compromising the confidentiality of the patients’ data. Interoperability in the IT system also forms the primary concern in the success of the health information technology in US. Interoperability is the ability of the systems and devices to share information and interpret the shared information. There is a need to agree on system standards for them to be interoperable at any level (Melvin, 2009). Health IT vendors in US use system that are not interoperable. One of the causes of interoperability problem is databases being unable to share the information with different types of applications (Vidyarthi, 2012). The system used by health IT vendor is in a proprietary format limiting access and transfer of information between the various providers. The model used in the systems is not standard, and they use different coded languages making it hard to share the needed health information. Even when there is sharing of information, terminologies used may be incompatible with applications used. The systems inability to share information effectively makes it very hard to address medical care fragmentation and solve error issues arising due to lack of necessary

Diet for a Patient with Chronic Hunger, Iron Deficiency Anemia, and Essay

Diet for a Patient with Chronic Hunger, Iron Deficiency Anemia, and Lead Poisoning - Essay Example His weight and height are equivalent to a 21 month old child. He is underweight and it is not a good indication of a normal nutrition for his age. The health of a child is assessed and evaluate according to the growth development of a child upon birth up to the current age to determine the development and the improvement of the childs growth. Poor growth may indicate health problem or potential health threat it also has a great impact on cognitive development and morbidity of a child. For children same as Jonathans age, the normal height should be 38.5 inches and weight of 16 kg as a normal values for boys age 30 months-old according to the CDCs growth chart. The results of Jonathan’s laboratory tests show low hemoglobin level and high lead level in his blood. Children in Jonathans age are high risks of getting lead poisoning. According to familydoctor.org, Toddlers explore their world by putting things in their mouths, there is a high probability that Jonathan might exposed his body to the things containing lead especially in the household. Although calcium can help fighting lead poisoning by preventing lead being absorbed in the body, iron is also an essential part of the process. Hemoglobin in the blood allows them to carry out the transport of oxygen, it carries protein in the blood. Decreased hemoglobin level in the blood may result to hematologic disorder, according to Pillitteri, hemoglobin is composed of globin, a protein dependent on nitrogen metabolism for its formation, and heme, an iron-containing pigment. Low hemoglobin level may cause Iron deficiency anemia due to low iron level in blood. This sections based on the childs nutritional assessment regarding food intake. In his case he drinks four glasses of milk or 32 ozs. per day. At Jonathans age he is ready to consume table food such as, meat, rice, bread, vegetables and fruits.

Case Study Example Therefore, one can assume that price increases will result in a reduction of revenues by 10%. Gross revenues are calculable for a number of options including; price flex, keeping a constant price, and an increase in price (Jain & Khanna 158). The biggest gross margin will be given by increasing prices, which Signode should do to maximize on their gross margins. While large and national markets segments have low profitability, Signode needs to ensure its existence as a supplier of steel strapping. If this is lost, getting it back will be a tall order (Jain & Khanna 159). To maintain their current market segment and the loyalty of customers, they should improve the perceived value of the clients who get customization in terms of strapping equipment, tools, and material. Since their competitors have lowered their process below Signode, reduction of price will not result in retention or gaining of market share. Signode could also lose their customers to Bentley or Alpha; therefore, it is essential to differentiate themselves from their main competitors. They should maintain their market share through differentiation from its competitors by taking advantage of customization (Jain & Khanna

The skills and attributes required to manage a hotel Assignment

The skills and attributes required to manage a hotel - Assignment Example It can be argued that the hospitality industry has transformed itself from a product-focused business to a customer-focused one and from a physical-asset intensive business to an experience-centric one. In order to understand the skills that are required by managers and employees in a hotel to perform better it is important to understand the concept of competencies. Competencies can be described as factors that improve the performance of individuals in jobs. According to the definition provided by Woodruffe (1993), competency provides â€Å"provide the dimension against which people should be assessed for readiness or potential to move into jobs against which they should be appraised and upon which they should be developed†. Skills has been defined as parameters that helps in achieving environmental goals by maximizing certainty of achievement by minimizing cost and time spent (Wadongo, Kambona and Odhuno, 2011). In the past three decades, large number of researchers has focused on the importance of skills and competencies required to run hotels. Skills and competencies are important for both managers and graduates who chose to enter in the hospitality industry. The ability to take initiative has been identified as one of the biggest skills needed to run hotels on the part of managers. This is because initiative can be identified as a parameter that is able to gain support and motivation from others. Hotels are visited by customers from all over the world and managers needs to guarantee satisfaction for the guests. In order to manage the guests and provide them proper satisfaction managers need to have three major types of skills namely conceptual skills, technical skills and human skills. Requirement of skills are further dependent on the hierarchy of the organization and the type of work of the employees. This implies

Digital Image Metadata and Exif files - Forensics Research Paper

Digital Image Metadata and Exif files - Forensics - Research Paper Example (University of Reading, 2011) Data of raster images are represented in the form of a pixel which is the smallest part of a display screen. Each pixel represents the colour and its intensity. Raster is a display space of x and y grid for two dimension image and x, y and z coordinate for three dimension images. The raster images are difficult to modify without loosing any information as they are mapped directly to the raster space. The size of raster image files is usually far more than the size of vector image files. The most common types of raster images files include BMP, GIF, TIFF, JPEG and PNG. (Whatis.com?, 1997) Tagged Image File Format (TIFF) type of digital images contains complete information about the images and no data is lost when saved. It is generally referred as â€Å"lossless† format. Their sizes are too big to be suitable for delivery by web. (University of Reading, 2011) Joint Photographic Experts Group (JPEG) type of digital images compresses data when saved. It looses its data whenever any modification is done and therefore generally referred as â€Å"lossy† format. It is good for delivery of photographic images by web. (University of Reading, 2011) Graphical Interchange Format (GIF) type of digital images is used for icons and graphics having limited range of colours. It does not loose information when saved and therefore generally referred as â€Å"lossless† format. It is good only for some types of images and used mostly on internet. (University of Reading, 2011) Portable Network Graphics (PNG) type of digital images is added recently in graphics file types. It has better compression result and support true colours. It is high quality and small size digital image file. (University of Reading, 2011) Data of vector images on the other hand is represented by vector objects which are geometrical figures such as lines, circles, rectangles, curves and many more shapes of geometry. Scaling, transformation, resizing, and resha ping are accurately done on vector images as its data is based on mathematical instructions. The most common types of vector image files have extension of SVG. They are used in software that is dedicated towards drawing and illustration such as Adobe Flash, CorelDraw, Inkscape, ACD Canvas, etc. Figure 1 shows comparison between digital images of Raster and Vector types. (JISC Digital Media, 2009) Figure 1: Comparison of Raster Images and Vector Images (JISC Digital Media, 2009) Metadata Metadata is the digital information that describes structure and relationship amongst different contents of digital data files. Earlier databases stored metadata as headers of the actual data files. Metadata is stored in a separate database file generally referred as registry or repository. For example, Windows operating system have registry in which the structure of entire hardware, device drivers and actual data is stored. (Bargmeyer & Gillman) The simplest example of metadata is an index of a book which gives the name of the chapters in the book and page numbers where it is located. If an index is removed from the book, it becomes extremely difficult to find any chapter whenever some information is needed. Similarly, metadata helps in organizing, storing, processing, retrieving and displaying contents of a data file which is otherwise meaningless. Metadata adds meaning to a data file by interpreting its contents according to its context. Digital Image files did not have

Proposal to add a Day Care Facility at Work Essay

Proposal to add a Day Care Facility at Work - Essay Example Contemporary business leaders require dynamic workers who are capable of meeting the demands of a high-stress and competitive work environment. From a theoretical perspective, these workers would need to be both motivated and free of distraction to avoid performance-related failures. Hence, in many respects, as today’s businesses are often focused on teamwork and team-building philosophies, it becomes the responsibility of the business leaders to invent new and innovative measures to boost employee morale and job satisfaction. Our facility, ABC Industries, a leader in manufacture and sale of technological components for automotive sound systems, maintains a staff of nearly 800, running on two split 12 hour shifts. In this high-stress environment, turnover ratios have been significantly high in recent months due to production demands, putting a significant strain on the human resources budget. Additionally, worker performance on the production floor has been down nearly 25 percent in the same time period due to worker anxiety over personal versus work-related schedule conflicts. Recent communications and anonymous surveys with production workers have indicated a desperate need for a corporate day care facility to assist in the demands of balancing home and work life. Many of ABC’s staff members have suggested that high gasoline prices combined with escalating day care costs have made them financially-motivated to find other employment which might offer a more lucrative salary package. This is something ABC Industries cannot afford. In this difficult economic environment, budgetary guidelines need to constantly be considered. However, the costs to the business in terms of reduced productivity and turnover expenses far exceed the costs associated with managing an in-house day care facility. Budgetary issues will be outlined in greater depth throughout this proposal, however it is appropriate to discuss its

Compare and contrast Russo-Chechen wars to Nagorno-Karabakh conflict Essay

Compare and contrast Russo-Chechen wars to Nagorno-Karabakh conflict. Discuss with special reference to theories of conflict - Essay Example A similar massacre of Azerbaijanis followed in the Armenian city of Spitak. The Armenian protests against Azerbaijan based on Nagorno-Karabakh actually started in the perestroika spirit, but it immediately turned out to be a political organisation called Karabakh Committee that stood for an extensive anticommunist coalition for national sovereignty and democracy. 1 Similarly, the war between Russia and Chechnya started with the ambition of the former to topple the latter’s president through military intervention. The military intervention turned out to be a complete warfare against the people of Chechnya through the invasion and brutal bombing of civil areas in an awkward attempt to bring down the Dudayev regime. The war also awoke the dormant fighting spirit of the Chechens which they had gained from their long martial tradition with roots from a century long, persistent warfare with the imperialist Russian empire in the nineteenth century. 2 The mounting loss on the Russian side provoked its generals to make a quick response to the Chechen resistance through indiscriminate artillery and aerial bombardment on Chechnya’s capital. The death toll of people in the city was huge and the city was levelled in every part in an attempt by Russia to subdue the Chechen defenders. 3 The conflict in the Nagorno-Karabakh autonomous area to separate from Azerbaijan and merge with Armenia that started in 1988 was called illegal with reference to the Soviet Constitution of 1978 that allowed merger of a region to another nation only with the permission of the home republic. The conflict in Southern Ossetia since 1990 is a similar case where the autonomous region is a part of north eastern Georgia and the war was provoked by the national administration and supported by the imperialists in Moscow. The support from Moscow was to weaken Georgia. The Georgian-Abkhazian conflict has been the bloodiest of all wars in the region. Though there are differences in

The law of media publicity contempt is obviously broken. The problem Essay

The law of media publicity contempt is obviously broken. The problem is that there is no better system that might reasonably su - Essay Example A strict implementation of prohibition laws such as the 1987 Act tend to clash, however, with certain basic human rights such as freedom of the press and the right to information. On top of this, advances in communication technology and the advent of globalisation make it doubly hard for authorities to fully impose sanctions on recalcitrant press and bloggers. Nonetheless, it would be wrong to say that the UK law on media publicity contempt is totally broken and that there is nothing that can be done about it. On the contrary, the UK media publicity contempt system has proven to be comparatively effective than those of other jurisdictions and the present state of the law presents a more mature approach in balancing between freedoms and obligations. State of the Law Media Publicity Contempt English media publicity contempt is governed primarily by the Contempt of Court Act 1981. It is a strict liability rule that does not take into consideration intent as an element in finding a verdi ct of guilt or absence of it and applies to publications, which include speech, writing and all other form of communications, addressed to the public. The strict liability rule applies only in the following cases: when publications create substantial risk in the obstruction or prejudice of judicial proceedings, and; the proceedings are active, as defined in Schedule 1 of said law. Schedule 1 describes an active proceeding, whether criminal or appellate, as the period from the time of a proceeding’s initial steps to the time of its conclusion, with initial steps including the arrest of the accused without warrant, the issuance of a warrant of arrest, the issuance of summons, the service of indictment or similar documents or oral charge. The conclusion stage of a proceeding includes the acquittal or any other verdict, which ends the proceeding or the discontinuance of the proceeding or by operation of law.1 The British law on media publicity contempt arose out of the 1820 case of R v Clement 2 where the Observer newspaper was fined ?500 for featuring a series of report on an ongoing trial. The case involved the trials of Cato Street conspirators who were then charged of treason for conspiring to kill members of the British Cabinet. The Observer was faithfully detailing the trials to the chagrin of the Government who was trying to conceal its substantive and procedural lapses. The newspaper’s editor was charged and tried in absentia for contempt for disregarding a court gag order. His subsequent appeal, which was also heard by almost the same judges who decided against him in the lower court contrary to the principle of natural justice, was dismissed.3 Since 1931, however, a â€Å"scandalising the court† case, or a case where the charge involves bringing down the authority of the judge or court through an act or publication, has not been successful in this jurisdiction.4 The 1981 Act came about as a result of the European Court of Human Right s (ECHR) decision in the case of The Sunday Times v United Kingdom5 where the newspaper featured a series of reports about the drug thalidomide that caused women to give birth to deformed babies during the pendency of the negotiations of settlement between

Live in Essay Example for Free

Live in Essay 22 August 2008 In January 2008, the Supreme Court validated long-term live-in relationships as marriages. A Supreme Court bench headed by Justice Arijit Pasayat with P Satasivan declared that children born out of such a relationship will no longer be called illegitimate. Law inclines in the interest of legitimacy and thumbs down whoreson or fruit of adultery, the court added. The apex court judgment was followed by similar suggestions from the National Commission for Women (NCW). In June this year, in response to recommendations made by the Ministry of Women and Child Development, the NCW sought a change in the definition of wife as described in Section 125 of the Criminal Procedure Code (CrPC), which deals with maintenance. The NCW recommended that women in live-in relationships should be entitled to maintenance if the man deserts her. Emphasising the need for broadening the definition of wife in the CrPC section, NCW officials said there had been cases where the man led the woman to believe that he was unmarried or was divorced or widowed and went ahead with the formalities required by marriage laws or the custom governing him. As a way of countering this, NCW chairperson Girija Vyas suggested that even if a marriage was not registered, a womans claim would stand if she provided enough proof of a long-term relationship. This underscored the Supreme Courts stand that a man and woman, having lived together for long, would be presumed to have been married, unless it was rebutted by convincing evidence. Equal rights The recent ruling is only the latest in a series of recommendations by various bodies seeking equal rights for the married woman and live-in female partner. A recommendation by the Justice Malinath Committee to the Law Commission of India (2003) stated that if a woman has been in a live-in relationship for a reasonable time, she should enjoy the legal rights of a wife. The Protection of Women from Domestic Violence Act (2005) provides protection to women at the hands of their husbands as well as live-in partners, and his relatives. When the law came into force in October 2006, it did not distinguish between the woman who is married and the woman who is in a live-in relationship. The SC ruling in itself has its precedent in a 1927 judgment made by the Privy Council, the Supreme Courts predecessor in pre-independent India. In A Dinohamy v. WL Blahamy, the Council laid down a general principle: Where a man and a woman are proved to have lived together as a man and wife, the law will presume, unless the contrary be clearly proved, that they were living together in consequence of a valid marriage and not in a state of concubinage. The Council made significant additions to the 1927 ruling in 1929 in Mohabhat Ali Vs Mohammad Ibrahim Khan. It said: The law presumes in favour of marriage and against concubinage when a man and woman have cohabited continuously for a number of years. For a live-in couple to be considered validly married, the court wanted evidence of cohabitation for a number of years, without specifying the minimum number of years. In Gokal Chand and Pravin Kumari (1952), the Supreme Court reiterated the 1929 principle. However, it added that though the presumption for a valid marriage between a live-in couple could be drawn from their long cohabitation, it wasnt enough to earn them legitimacy if the evidence of their living together was rebuttable. In this judgment, the apex court refused to recognise a live-in relationship, though the couple had lived together for some years before the pregnant woman decided to live alone with her child born out of a live-in relationship with the man. The rebuttal of a presumption in favour of a valid marriage, in this case, came from the child, who said she did not remember her father ever visiting her or her mother. In Badri Prasad (1978), the Supreme Court recognised a live-in relationship as a valid marriage, accusing the authorities of questioning a relationship 50 years after the couple had begun living together, and were treated as a married couple even by their relatives. The view from the courts A Madhya Pradesh High Court judgment in 1985 dealt with the case of Loli, who had lived for several years with Radhika Singh. Together they had five daughters and a son. The trial court dismissed the case made by Singhs sister-in-law that Loli should not have property rights as she was just a mistress. The sister-in-law had sought her rights over the property, and contended that Loli had started living with Singh even when her first husband was alive, and therefore, there could not be a presumption of valid marriage. But the appellate court set aside the trial courts order, a stand the Madhya Pradesh High Court also agreed with. This brings us to Payal Sharma Vs Superintendent, Nari Niketan, and others, in which a court stated in 2001 that a live-in relationship was not illegal. Sharma had moved the Allahabad High Court to be left to do her own bidding after being forced to live in a Nari Niketan at Agra, following her arrest, along with Ramendra Singh, with whom she had a live-in relationship. The Agra police arrested her and Singh on the basis of an FIR lodged by her father, accusing Singh, an already married man, of kidnapping Sharma. A resident of Kannauj district in Uttar Pradesh, Sharma produced documentary evidence, including her high school certificate, to prove that she was 21 years old. On the basis of this evidence, the court directed the authorities to set her free. Justice M Katju and Justice RB Mishra stated, Petitioner Smt. Payal Sharma appeared before us and stated that she is above 21 years of age, which is borne out from the high school certificate which shows that her date of birth is 10. 7. 1980. Hence she is a major and has the right to go anywhere and live with anyone. In our opinion, a man and a woman, even without getting married, can live together if they wish to. This may be regarded as immoral by society, but is not illegal. There is a difference between law and morality. Thus, a uniform view appears to emerge from the courts, when one looks at the history of cases on the question of live-in relationships. It appears that, by and large, legal sanction for live-in relationships is based on the assumption that they are not between equals, and therefore women must be protected by the courts from the patriarchal power that defines marriage, which covers these relationships too. Shades of grey But such protective sanction raises other questions, notably about the institution of marriage itself, for which there are no easy answers. Supposing a live-in relationship is between a man who is already married with children, and a single woman? In Payal Sharma, Ramendra Singh was a married man with children. Which womans interest should the courts and law protect, and in doing so, can the apparent equality between married and unmarried couples be maintained? Live-in relationships also raise questions about legal stance towards bigamy. In spirit and essence, the Allahabad High Court judgement contradicts the law against bigamy for Hindus, both for men and women, which make it mandatory for a husband or wife to get a divorce before they can marry again. When bigamy is illegal except for Muslims in what sense can a live-in relationship be equal to a marriage, if either the man or the woman is already married? And how is it that a division bench of a High Court is able to pronounce a judgement that openly violates the social, legal and filial implications that bind the husband in a Hindu marriage, which includes living with the wife and children under the same roof? Theres also the question of marriage-like protection for a woman who enters a relationship with someone she isnt married to, by choice or circumstance. Does a female partner need the protection of legal standing equivalent to that of a wife, in a non-married relationship she entered into by choice or circumstance? To marry, or not to marry? Live-in relationships among urban, educated, upper-middle class young people began as a declaration of independence, as a way of keeping away from the shackles of institutionalised marriages. In fact, its a willful rejection of the institution of marriage, of the stereotypes it engenders, and of the restrictions and inequalities it has come to stand for. But, legal sanction granted to a live-in relationship may put it back in the trap that live-in partners sought to evade in the first place. This legal sanction implies that live-in relationships are bound by the same rules of fidelity, commitment and economic stability that marriage is structured in. Social geographer Soma Das says that people who opt for live-in relationships do so because they do not believe in marriage. If live-in relationships are treated on par with marriage, many young men and women may not really like to get into such open relationships. At the other end, ensuring maintenance and giving legal sanction to live-in relationships will not make the position of the female partner equal to that of the wife because social acceptance in Indian society will take a very long time. It still does not have a mindset that accepts the estranged female partner of a live-in relationship. Psychologist Shenaz B Ilavia believes that live-in relationships are still confined to a marginal segment of society which she calls the elite, upper middle class. Theoretically, it may sound like a better proposition than marriage, but very few people actually opt for it. A live-in relationship is not a substitute for marriage, she says.

AirAsia Berhad (AirAsia) | Analysis

AirAsia Berhad (AirAsia) | Analysis Introduction AirAsia Berhad (AirAsia) is one of the leading low cost airlines in South East Asia which has expanded rapidly since 2001. The company is based in Kuala Lumpur, Malaysia and has successfully positioned itself in customers mind through the simple slogan Now Everyone Can Fly (AirAsia, 2009). The company is currently valued at approximately RM2.7 billion and has a total of 60 aircrafts that fly to over 50 domestic and international destinations with over 400 domestic and international flights daily (Euromonitor International, 2009). The operation for the short and long haul are handled by AirAsia and its sister company, AirAsia X Sdn Bhd (AirAsia X). AirAsia aims to establish itself as a leading low cost carrier in market by valuing its customers through cost advantages created by operational effectiveness and efficiency. More customers are able to fly taking into consideration the low fare charges as AirAsia capture segments of customers that previously could not afford the airlines fare. Whether the strategy exploits the companys key resources Each organisation is unique in terms of it resources and capabilities and the key to success merely depend on its ability to find or create a competence that is distinctive (Teece et.al.,1997). The Resource Based View (RBV) combines two perspectives, the internal analysis of phenomena within an organisation and an external analysis of the industry and its competitive environment (Collis and Montgomery, 1995). It goes beyond the Strengths, Weaknesses, Opportunities and Threats (SWOT) analysis by integrating internal and external perspectives. The ability of an organisations resources to present competitive advantages could not be determine without taking into considerations the boarder competitive concept. Barney (1995) indicated that organisations resources and capabilities must be evaluated in terms of value, rarity, imitability or non-substitutability (VRINE model). The value of the resources and capabilities interacts with the market sources and will differ based on time and industry. The three fundamental market forces; scarcity, demand and appropriability determines the value of a resources and capabilities (Collis and Montgomery, 1995). In order to answer the question of value, organisation could identify whether the resources and capabilities are able to meet market demand. As for AirAsia, the organisation relies on its human resources and management capabilities wherein these two components have satisfied the value requirement as it has been able to meet the demand for the Low Cost Carrier (LCC) market. The resources and capabilities own by AirAsia are homogenous in the market however aspect such as work culture and innovative routes differs it from the competitors. In applying the RBV concept, AirAsia has a competitive parity based on its valuable and not rare resources and capabilities. Immitability is something generic in the airline in dustry as aircraft, fast turnarounds time and others are easily duplicate. One of AirAsias imitable characteristics is path dependency wherein a characteristics of resources is developed and/or accumulated through a unique series of time. AirAsias work culture of openness between employees as well as the leadership from its Chief Executive Officer is something have been built up over a period of time which is difficult to duplicate. Moreover, the high capital requirement for market entry is another factor that leads to difficulty to imitate the resources and capabilities. It is undeniable that the said resources and capability be imitated as competitors will identify the same however it will take time and meanwhile, AirAsia gain the competitive advantages. Having a control and exploiting the resources and capabilities provides competitive advantages to the organizations (Carpenter and Sanders, 2009). AirAsia has exploited it resources and capabilities which is shown in the financial performance. AirAsia has gradually increased its performance throughout the years. AirAsias s net profit for the 3rd quarter of 2009 totalled RM130 million ($38.4 million) which is sustained by rising passenger numbers and income from add-on services. The profit achieved was a turnaround from a RM466 million ($137 million) net loss in the same period last year (www.airasia.com). The fit of the strategy to current industry conditions The competitive environment consists of many factors that are particularly relevant to an organisations strategy. Analysing the external environment particularly the industry is a starting point for firms to develop a strategy. Porters five forces include the overall structure rather than focusing to any one element. However the forces are not stagnant which tendency to change may occur. AirAsia operates within the airline industry and forces that are driven in the industry would identify the strength and weaknesses of the organisation. There is potential market in the Asia for LCC due to the rapid economic and disposable incomes growth. Infrastructure such as high speed trains and highways has yet to meet the high standard level and therefore customers tend to choose the air as mode of transportation. Hence, threats of substitutes are low as the geographical structure of Asia has made air travel the viable, efficient and convenient mode of transportation. Looking into this scenario, AirAsia entered the airline industry concentrating on the LCC and noted that at the initial stage there were less rivalry but as the industry grows, the rivalry among established firms become higher partly due to price issues. AirAsias main competitors are Firefly, Tiger Airways and Jetstar Asia. Knowing the said changes, AirAsia applied the adaptation process (Hanan Freeman, 1984) by expanding its operation to long haul services to various destinations. Moreover, AirAsia realise the price is destructive and try to avoid direct price c ompetition and try to create a friendly competition environment. As there is positive growth in the airline industry, full service airline carriers have refocused its operation related to costs and yields as it is seen as a requirement to maintain profitability (Graham and Vowles, 2006). There is possibility of new entrance by other LCC which creates further competition in the industry. For example, Firefly set up by Malaysia Airline System Berhad is a part of LCC industry in Malaysia that has adapted AirAsias low cost concept. However, it would not be a threat to AirAsia as Hanan Freeman (1984) highlighted it is difficult to imitate as tacit amount of knowledge is required on the targeted firm. The high capital requirement and government barriers air service agreement can act as barriers to entry. Due to significant growth within the industry, demand for additional aircraft has increased and suppliers will be in a powerful position. It was reported that Asia accounts for 40% of new aircraft orders for Boeing and Airbus and seat capacity on LCC worldwide has more than doubled in the past four years (Shameem, 2006). Due to few players, Boeing and Airbus and lack of competition in the market, the bargaining power of suppliers are low. Consequently there is not much competition in terms of pricing occurring between the two companies so an airline carrier will have to accept an offer from one of the suppliers. The bargaining power for buyers is low as there is no room to bargain for cheaper tickets as AirAsia provides the lowest price compared to other carriers. The biggest threats for AirAsia are the rivalry and risk of entry with the existing and potential competitors. LCC business is viable and there is healthy profitability provided AirAsia continuously improves itself and is flexible in the challenging market. The sustainability of the differentiators Porter (1996) indicated that to outperform rivals, an organisation need to deliver greater value to customers or/and build comparative value at a lower cost. The airline industry is at the growing stage and therefore stiff competition from existing and new LCC is expected in the future. In order to sustain its competitive advantage, AirAsia needs to leverage its competency in creating cost advantages. At present, AirAsia differentiates by providing substantially low fares with no frills concept by offering innovative routes. Murray (1988) indicated that there is uncertainty for sustainable differentiation to be achieved through product innovation and suggested that the area that could be concentrated for the said differentiation is quality and service. While, Porter (1996) highlighted that positioning are successful based on activity system and simple consistency between each activity aligning with the organisation strategy. AirAsia builds it brand name by providing a good quality service at a low price. During inception, AirAsia focused on internal destinations and have further entered the international destinations. AirAsia X is differentiated by its long haul LCC as customers would not need to look at different carriers to reach different destinations at a lowest price. It is based on the same no frills service model wherein the price is 80% lower than its competitor together with additional services that requires customer to pay additional payment such as food, entertainment and others. AirAsia also seek to create excitement amongst their customers with the range of innovative and personalized service such as self check-in. Due to AirAsias success in the industry, competition might one to adapt the companys business model. However, AirAsia had some advantages over its competitors by the advantage of experience and its brand enjoyed good recognition. AirAsia gain from the first mover advantage which allows it to establish itself before competition perceive further in this low cost segment, apart from competition that already exists across segments (low cost vs full service carriers). AirAsia has the strength to lay down the rules and framework in the industry for business and operational suitability. Through AirAsia philosophy of Now Everyone Can Fly, AirAsia has embarked a revolution in air travel with more and more people around the region choosing AirAsia as their preferred choice of transport. As Air Asia continuously strives to promote air travel, AirAsia also seek to create excitement amongst their guests with they range of innovative and personalized service. Moreover customer loyalty is build by the differentiation which could act as a defense against rivalry (Eng, 1994). Whether the elements of the strategy are consistent and aligned with the strategic position Strategy works as a driver in a firm in achieving goals and objectives (Carpenter and Sanders, 2009). AirAsias five strategy elements are as follows: Porter (1996) presented three generic strategies that an organisation could use to overcome the five forces and achieve competitive advantage. However, there were studies resulting that adapting one or more forms of competitive advantage will outperform better (Murray, 1988). In the LCC segment, cost is the competitive priority and it determines market position. In lieu of this, Airasia has applied the focused cost leadership strategy wherein it targets on specific markets; price sensitive customers as well as lowering its overall costs (Flouris and Walker, 2005). With the positive growth in the LCC, it will create opportunity to others to enter the market. Competition between carriers using the same business model will inevitably be intense. One of the major pitfall against attempting to differentiate is by trying to combine low cost and differentiation strategy by starting to add frills in its business model. However, by applying the said strategy, carriers have lost their source of competitive advantage by narrowing the strategic cost gap. Every frill or service adds to cost and reduced the strategic cost gap, thus curbing the flexibility to offer innovative price deals. Murray (1988) disagrees that cost structure is vital in relation to the output performance compared to the price sensitivity. Factors such as economy of scale and quality of management teams within the organization could be the benchmark for cost leadership. Under the cost leadership strategy, level of operation efficiency is vital as it assist in achieving cost advantages than the rivals by searching continuous areas for cost reduction along its value chain that leads to economies of scale (Eng, 1993). AirAsia increases its efficiency through increased route network and its operating activities by adapting cost optimising techniques such as quick turnaround times and maximizing of flight utilisation for its aircrafts (Shari, 2003). As the result from efficient operation, it minimizes the cost that is then passed on to customers so that affordable air travel can become a reality. In 2005, the cost per available seat mile (ASK) for Airasia was only 0.3 compared to the next lowest valu e from 0.6 being Firefly (www.airasia.com). AirAsia took advantage from the existence of e-commerce which is cheaper and easier technique in providing information about products and services. Furthermore, it gives a better and more convenient way of promoting the companys product and services. The cost related to web is very low compared to other methods like advertisement on television. AirAsia has taken advantage from this method to reduce the cost of operations that leads to operating on a low rate. Malaysia government has supported AirAsia through the opening of the LCC terminal in Kuala Lumpur International Airport which enhanced its competitive edge by reducing costs and better logistic planning (Euromonitor International, 2009). Competitors tend to know how big the market is and how good the opportunity is in Asia. Therefore, there is threat by competitors which could imitate AirAsias low cost base. Most of the competitors have the same concept of no frills and low price strategy and will continuously try to reduce its costs than AirAsia in order to gain sustainability in the market. The challenge for AirAsia is to reduce cost effectively which it is difficult for the competitors to copy. Possible issues associated with implementation Strategy formulation and implementation are interdependent with the objectives being a coherent set of strategy elements and implement levers (Carpenter and Sanders, 2009). In order to succeed in the LCC segment, AirAsia will need to maintain its low cost elements in their business design as it is critical to the long term success. The main reason is because the more gap between arises between the competiting airlines, the more flexibility will be available to offer lower price and gain market share. An extended route system will most certainly be a key differentiator and to sustain its competitive advantages, resources and capabilities need to be analysed further. Around the world, it has been observed that low cost airlines pursuing a generic business design have emerged as the most successful. Conclusion AA actual main strength was based in its innovative ways to keep the cost low which was hard to imitate. AirAsia has indicated that synergies between the internal and external factors could develop a competitive advantage. This has allowed AirAsia to positioned and be the market leader in the LCC. The brand name brand equity is a major strength that AirAsia must successfully capitalize. Bibliography Barney J.B.

Electromagnetic Suspension Prototype Design

Electromagnetic Suspension Prototype Design ABSTRACT Electromagnetic suspension works where two or more electromagnets of the same polarity absorb all the bumps. The main problem is making the magnets strong enough when running off a cars electrical system. This work describes techniques for the design analysis of a prototype magnetic suspension system. The viability of future high temperature super conducting magnet designs for MAGLEV has been investigated with regard to their application to active secondary suspension. It has also analysed and compared the functions and performances of the magnetic suspension system with the hydraulic, and air suspension systems. CONCLUSION The design and modelling process of a 1/5-scale flux-cancelling Maglev suspension has been described in this paper. Using approximate techniques, this design can be used to predict the analysis. With comparison to other types of suspension system, electromagnetic suspension system provides totally comfortable ride. Chapter 1 INTRODUCTION As the knees are the important part of the human body because of which he can walk, run, sit and jump properly, the suspension system is a knee of a vehicle, with which the vehicle can give us a comfortable ride. The suspension system connecting a vehicle body to the wheels and its tyres allows the wheels to move in an essentially vertical direction in response to road surface irregularities, a spring temporarily stores energy, thus insulating the vehicle body from acceleration peaks. A shock absorber or damper ensures that oscillations induced by the road unevenness or aerodynamic forces (or by accelerating, braking or lateral forces), which would impair ride comfort and road holding. 1.1 Background: If all is well, the suspension dampers on a vehicle do their work quietly and without fuss. Like punctuating or acting, dampers at their best when they are not noticed. Drivers and passengers simply want the damper to be trouble free. For the designers, however, there is a satisfaction in creating a good, new damper for a racing car or rally car, and perhaps making some contribution to competition success. Less exiting but economically more important, there is also satisfaction in seeing everyday vehicle travelling safety, with comfortable occupants, at speed that could be quite impractical without good dampers. The current worldwide production of dampers is difficult to estimate with accuracy, but it is probably around 50 to 100 million units per year with retail value well in excess of one billion dollars per year. The fitting of damping devices to the vehicle suspensions followed rapidly on the heels of the arrival of the motor car itself. Since those early days, the damper has passed through a century of evaluation, the basic stages of which may be considered as: Dry friction (snubbers) Blow-off hydraulics Progressive hydraulics Adjustable (manual alternation) Adaptives (slow automatic alternation) Semi active (fast automatic alternation) The zeitgeist regarding dampers has changed considerably over the years, in roughly the following periods: Up to 1910, dampers were hardly used at all. In 1913, Rolls Royce actually discontinued rear dampers on a Silver Ghost, illustrating just how different the situation was in the early years. From 1910 to 1925, mostly dry snubbers were used. From 1925 to 1980, there was a long period of dominance by simple hydraulics, initially simply constant force blow-off, then a proportional characteristics, then adjustables, leading to mature product. From 1980 to 1985, there was excitement about the possibilities for the active suspension, which could effectively eliminate the ordinary dampers. From 1985, it became increasingly apparent that good deal benefit of active suspension could be obtain much more cheaply by fast auto-adjusting dampers, and the damper suddenly became an interesting, developing component again. Damper types which are explained fully later can be initially classified in two ways: Dry friction with solid elements. Hydraulic with fluid elements. In 1966 Danby and Powell proposed an EDS system for high-speed transportation using super conducting magnets with a null flux suspension. Other designs were later proposed using continues sheet guide ways. Subsequent researchers in the U.S., Japan, Germany, UK and Canada have developed further innovations (such as ladder type guide way for increased lift efficiency), but there are still a number of technical problems that needed resolution. 1.2 Current Details Of Electromagnetic Suspension (Maglev): There are three primary types of Maglev technologies: superconducting magnets ( electrodynamic suspension) feedback controlled electromagnets ( electromagnetic suspension) Newer potentially more economical system using permanent magnets Inductract. The several approaches and designs have been produced by Japan and Germany. These two countries are very active in maglev research. The design used for trains in which the train levitate by the repulsive force of the same poles of the magnets. A linear motor is used to propel the trainor on the locomotive or both. In this system massive electricalinduction coils produce the magnetic field which are placed along the tracknecessary to propelthe train, leading some to speculate that the cost of constructing such tracks would be enormous. Magnetic bearings are unstable because ofEarnshaws theorem; Conventional maglev systems are stabilized with electromagnets that have electronic stabilization. The electromagnets and electronics tend to be large, power-hungry, and expensive. To levitate the train a very strong magnetic field is required but large electromagnet is also a big issue for the design, so instead of using the large magnets, superconductor for an efficient electromagnet. Inductrack is a new and less expensive system. The system depends on the current induced in the passive electromagnetic array by permanent magnets, so that it provides the better load carrying capacity related to the speed. In the prototype, thepermanent magnetsare in a cart; horizontally to provide lift, and vertically to provide stability. The array of wire loops is in the track. The magnets and cart are unpowered, except for the speed of the cart. Inductrack was originally developed as a magnetic motor and bearing for a flywheel to store power. With only slight design changes, the bearings were unrolled into a linear track. Inductrack was developed by physicist William Post atLawrence Livermore National Laboratory. For stabilization Inductrack uses Halbach arrays. The function of the Halbach arrays is to stabilize the loops of wires with the help of permanent magnets without electronic stabilization. Halbach arrays were originally developed for beam guidance ofparticle accelerators. Currently, some space agencies, such as NASA, are researching the use of maglev systems to launchspacecraft. In order to do so, the space agency would have to get a maglev-launched spacecraft up toescape velocity, a task which would otherwise require elaborate timing of magnetic pulses or a very fast, very powerfulelectric current. 1.3 Aims and Objectives: Aim: To design and analyse a prototype Magnetic Suspension System. Objectives: Literature Review Research the principles of the various types of suspension systems and analysing their functions and performances. Investigate the application of the magnetic suspension system. Design a prototype Magnetic Suspension System. Analyse the designed Magnetic Suspension System. Compare with the other type of Suspension Systems. Conclusion. Chapter 2 Literature Review 2.1 Principle: The basic principle is to develop a contact less spring; the instability will be corrected with electromagnetic actuators. Electromagnetic suspension works where two or more electromagnets of the same polarity absorb all the bumps. The main problem is making the magnets strong enough when running off a cars electrical system. Electrodynamics magnetic suspension called EDS maglev and referred to as repulsive Maglev because it relies on repulsive magnetic Forces, has the capability of allowing high speed transportation with a relatively large gap between the vehicle and guide way . 2.2 Basic Concept: Have a set of shock with magnet inside them that are used as the fork setup. There is one magnet at the top of the inner portion of the cylindrical shock sleeve with the north polarity facing down towards the ground. The second magnet sits on the top of the inner shock that pivots up and down. This magnet has the north polarity upwards so its parallel with the other magnet. The two magnet fights against each other giving the forks travel. There is also an adjustment at the top of the shock, which allow the magnet to become closer .together for a stiffer travel or further apart for softer travel. 2.3 Dynamics of the magnetic suspension system: The basic principle of a simple electromagnetic suspension system is shown in Fig.1. The magnetic force applied by the electromagnet is opposite to gravity and maintains the suspended steel ball in a levitated position. The magnetic force Fm depends on the electromagnet current I, electromagnet characteristics, and the air gap X between the steel ball and the electromagnet. The motion of the steel ball in the magnetic field is expressed as Where m is the mass of the suspended steel ball, G = mg is the gravity force, and X is the air gap between the steel ball and the electromagnet. The magnetic force Fm is a nonlinear function of the current I and the air gap X. The linearization of the static characteristic near the set point (F0 , X0 ,I0) is given as The voltage equation of the electromagnetic coil is expressed as Where U is the controlled voltage applied to the electromagnet, R is the coil resistance, and L is the inductance of the electromagnet. Inductance L=f (X, t) is a function of the air gap, the coil, the core, and the steel ball. The steady state of the operating point air gap between the mass and the electromagnet is maintained by generating the magnetic force which is adjusted so that the gravitational force of the steel ball is balanced. The small differences from the operating point are normalized over operating spaces (G, D, Imax , Umax) and they are defined as follows: Where f is the normalized resultant force, x is the normalized air gap, i is the ormalized current, and u is the normalized voltage. X0 , I0 , and U0, are the steady-state values. Substituting Eq. 4 into Eqs. 1, 2, and 3 the dynamics of the system can be presented as follows: The block diagram of the linearized model of the electromagnetic suspension system is shown in Fig. 2. The linear system described in the block diagram in Fig. 2 is unstable and controllable. 2.4THEORY OF VIBRATION: Any motion that repeats itself after an interval of time is called vibration or oscillation. The swinging of a pendulum and the motion of a plucked string are typical examples of vibration. The theory of vibration deals with the study of oscillatory motions of bodies and the forces associated with them. Free vibration without damping Simple Mass Spring Model To start the investigation of the mass-spring-damper we will assume the damping is negligible and that there is no external force applied to the mass (i.e. free vibration). The force applied to the mass by the spring is proportional to the amount the spring is stretched x (we will assume the spring is already compressed due to the weight of the mass). The proportionality constant, k, is the stiffness of the spring and has units of force/distance (e.g. lbf/in or N/m) The force generated by the mass is proportional to the acceleration of the mass as given byNewtons second law of motion. If we assume that we start the system to vibrate by stretching the spring by the distance ofAand letting go, the solution to the above equation that describes the motion of mass is: This solution says that it will oscillate withsimple harmonic motionthat has an amplitudeofAand a frequency offn.The numberfnis one of the most important quantities in vibration analysis and is called theundamped natural frequency. For the simple mass-spring system,fnis defined as: Note:Angular frequency?(? = 2pf) with the units of radians per second is often used in equations because it simplifies the equations, but is normally converted to standard frequency (units ofHzor equivalently cycles per second) when stating the frequency of a system. If you know the mass and stiffness of the system you can determine the frequency at which the system will vibrate once it is set in motion by an initial disturbance using the above stated formula. Every vibrating system has one or more natural frequencies that it will vibrate at once it is disturbed. This simple relation can be used to understand in general what will happen to a more complex system once we add mass or stiffness. For example, the above formula explains why when a car or truck is fully loaded the suspension will feel softer than unloaded because the mass has increased and therefore reduced the natural frequency of the system. What causes the system to vibrate: from conservation of energy point of view Vibrational motion could be understood in terms ofconservation of energy. In the above example we have extended the spring by a value ofxand therefore have stored somepotential energy(12kx2) in the spring. Once we let go of the spring, the spring tries to return to its un-stretched state (which is the minimum potential energy state) and in the process accelerates the mass. At the point where the spring has reached its un-stretched state all the potential energy that we supplied by stretching it has been transformed intokinetic energy(12mv2).The mass then begins to decelerate because it is now compressing the spring and in the process transferring the kinetic energy back to its potential. Thus oscillation of the spring amounts to the transferring back and forth of the kinetic energy into potential energy. In our simple model the mass will continue to oscillate forever at the same magnitude, but in a real system there is always something calleddampingthat dissipates the energy and therefore the system eventually bringing it to rest. The solution to this equation depends on the amount of damping. If the damping is small enough the system will still vibrate, but eventually, over time, will stop vibrating. This case is called underdamping this case is of most interest in vibration analysis. If we increase the damping just to the point where the system no longer oscillates we reach the point ofcritical damping(if the damping is increased past critical damping the system is called overdamped). The value that the damping coefficient needs to reach for critical damping in the mass spring damper model is: To characterize the amount of damping in a system a ratio called thedamping ratio(also known as damping factor and% critical damping) is used. This damping ratio is just a ratio of the actual damping over the amount of damping required to reach critical damping. The formula for the damping ratio (?) of the mass spring damper model is: For example, metal structures (e.g. airplane fuselage, engine crankshaft) will have damping factors less than 0.05 while automotive suspensions in the range of 0.2-0.3. The solution to the underdamped system for the mass spring damper model is the following: The value ofX, the initial magnitude, andf,thephase shift, are determined by the amount the spring is stretched. The formulas for these values can be found in the references. 2.5 HALBACH ARRAYS Another way of stabilizing the repulsive effect is to use fields that move in space, rather than just time. This effect can be demonstrated with a rotating conductive disc and a permanent magnet, which will repel each other. HALBACH CYLINDERS are well-suited to magnetic levitation of gyroscope, motor and generator spindles. They use only permanent magnets and unpowered conductors to provide levitation. The energy of suspension comes entirely from rotational motion, efficiency is good, and no extremely low temperature suspension magnets or electronics are required. The only restriction is that the linear speed at the bearing race must be above a meter per second to levitate. This is also the principle of the inductract maglev train system, which avoids the problems inherent in actively supported systems. Halbach Cylinder: A Halbach cylinder is a magnetized cylinder composed of ferromagnetic material producing (in the idealised case)a magnetic field confined entirely within the cylinder with zero field outside. The cylinders can also be magnetized such that the magnetic field is entirely outside the cylinder, with zero field inside. Several magnetization distributions are shown below: Ideally, these structures would be created from an infinite length cylinder of magnetic material with the direction of magnetization continuously varying. The magnetic flux produced by this ideal design would be perfectly uniform and be entirely confined to the bore of the cylinder. Of course, the ideal case of infinite length is not realisable and in practice the finite length of the cylinders producesend effectswhich introduce non-uniformities in the field within the bore. The difficulty of manufacturing a cylinder with a continuously varying magnetization also usually leads to the design being broken into segments. These cylindrical structures are used in devices such as brushless AC motors, magnetic couplings and high field cylinders. Both brushless motors and coupling devices use multipole field arrangements: Brushless motors typically use cylindrical designs in which all the flux is confined to the centre of the bore (such ask = 4above, a six pole rotor) with the AC coils also contained within the bore. Such self-shielding motors designs are more efficient and produce higher torque than conventional motor designs. Magnetic coupling devices transmit torque through magnetically transparent barriers (that is the barrier is non-magnetic or is magnetic but is not affected by an applied magnetic field), for instance between sealed containers or pressurised vessels. The optimal torque couplings consists of a pair of coaxially nested cylinders with opposite +kand -kflux magnetization patterns, as -k magnetization patterns produce fields entirely external to the cylinder. In the lowest energy state, the outer flux of the inner cylinder exactly matches the internal flux of the outer cylinder. Rotating one cylinder relative to the other from these state results in a restoring torque. where the inner and outer cylinder radii areRoandRi, respectively.His in theydirection. This is the simplest form of the Halbach cylinder, and it can be seen that if the ratio of outer to inner radii is greater thanethe flux inside the bore actually exceeds theremanenceof the magnetic material used to create the cylinder. This cylindrical design is only one class of design which produces a uniform field inside a cavity within an array of permanent magnets. Other classes of design include wedge designs, proposed by Abele and Jensen in which wedges of magnetized material are arranged to provide uniform field within cavities inside the design as shown below. Three designs producing uniform magnetic fields within their central air gap The direction of magnetization of the wedges in (A) can be calculated using a set of rules given by Abele, and allows for great freedom in the shape of the cavity. Another class of design is the magnetic mangle (B), proposed by Coey and Cugat, in which uniformly magnetized rods are arranged such that their magnetization matches that of a Halbach cylinder, as shown for a six rod design. This design greatly increases access to the region of uniform field, at the expense of the volume of uniform field being smaller than in the cylindrical designs (although this area can be made larger by increasing the number of component rods). Rotating the rods relative to each other results in many possibilities including a dynamically variable field and various dipolar configurations. It can be seen that the designs shown in A and B are closely related to thek = 2Halbach cylinder. Other very simple designs for a uniform field include separated magnets with soft iron return paths, as shown in figure (C). High Uniform Field Designs: If the two dimensional magnetic distribution pattern of the Halbach cylinder is extended to three dimensions, the result is the Halbach sphere. These design have extremely uniform field within the interior of design, as they are not affected by the end effects prevalent in finite length cylinder design. The magnitude of the uniform field for a sphere also increases to 4/3 the amount for the ideal cylinder design with the same inner and outer radii. However, being spherical access to the region of uniform field is usually restricted to a narrow hole at the top and bottom of the design. Higher fields are possible by optimising the spherical design to take account of the fact that it is composed of point dipoles (and not line dipoles). This results in the stretching of the sphere to an elliptical shape and having a non-uniform distribution of magnetization over the component parts of the sphere. Using this method, as well as soft pole pieces within the design, 4.5 T in a working volume of 20mm3was achieved by Blochet al.in 1998 and this was increased further to 5 T in 2000, although over a smaller working area of 0.05mm3. As hard materials are temperature dependent, refrigeration of the entire magnet array can increase the field within the working area further as shown by Kumadaet al.This group also reported development of a 5.16 T Halbach dipole cylinder in 2003. Chapter 3 MAGNETIC MATERIALS Magnets are attracted to, or repelled by, other materials. A material that is strongly attracted to a magnet is said to have permeability. Iron and steel are two examples of materials with very high permeability, and they are strongly attracted to magnets. Liquid oxygen is an example of something with a low permeability that it is actually slightly repelled by magnetic fields. Everything has a measurable permeability like people, gases and even the vacuum of outer space. The SI unit of magnetic field strength is the tesla, and SI unit of total magnetic flux is the Weber. 1 Weber = 1 tesla following through 1 square meter, and is a very large amount of magnetic flux. Material can be classified according to their permittivity and conductivity. Materials with a large amount of loss inhibit the propagation of electromagnetic waves. In this case, generally whens/(?e)>> 1, we consider the material to be a good conductor. Dielectrics are associated with lossless or low-loss materials, wheres/(?e) 3.4 Measurement: The dielectric constant of material can be found by a variety of static electrical measurement. The complex permittivity is evaluated over a wide range of frequencies by using different variants of dielectric spectroscopy, covering 21 orders of magnitude from 10-6to 1015Hz. Also, by usingcryostatsand ovens, the dielectric properties of a medium can be characterized over an array of temperatures. In order to study systems for such diverse exciting fields, a number of measurement setups are used, each adequate for a special frequency range. Low-frequencytime domainmeasurements (10-6-103Hz) Low-frequencyfrequency domainmeasurements (10-5-106Hz) Reflective coaxial methods (106-1010Hz) Transmission coaxial method (108-1011Hz) Quasi-optical methods (109-1010Hz) Fourier-transform methods (1011-1015Hz) 3.5 Magnet used for Inductrack Inductrack is a completely passive, fail-safe magnetic levitation system, using only unpowered loops of wires in the track and permanent magnets (arranged into Halbach Arrays) on the vehicle to achieve magnetic levitation. The track can be in one of two configurations, a ladder track and a laminated track. The ladder track is made of unpowered Litz-wire cables, and the laminated track is made out of stacked copper or aluminium sheets. Description: Inductrack was invented by a team of scientists at Lawrence Livermore National Laboratory, headed by physicist Richard F. Post, for use in maglev trains. The only power required is to push the train forward against air and electromagnetic drag, with increasing levitation force generated as the velocity of the train increases over the loops of wire. Its name comes from the wordinductanceorinductor; an electrical device made from loops of wire. As the magnet array (with alternating magnetic field orientations) passes over the loops of wire, it induces a current in them. The current creates its own magnetic field which repels the permanent magnets. Whenneodymium-iron-boron permanent magnetsare used, levitation is achieved at low speeds, allowing it to lift 50 times the magnet weight. The test model levitated at speeds above 22 mph, but Richard Post believes that on real tracks, levitation could be achieved at as little as 1 to 2 mph. Below the transition speed, the magnetic drag increases as the vehicles speed increases and approaches the transition speed, but above this transition speed, the magnetic drag decreases as the vehicles speed increases. The Inductrack II variation uses two Halbach arrays, one above and one below the track to double the levitating magnetic field without substantially increasing the weight or footprint area of the Halbach arrays, while having lower drag forces at low speeds. Several maglev railroad proposals are based upon Inductrack technology. The U.S.National Aeronautics and Space Administration(NASA) is also considering Inductrack technology for launching rockets. Stationary cars: For use at embarkation/ debarkation areas, an implementation using a moving track would continue levitating the car while stationary. With a loop construction similar to a flat escalator by stationary track there would be no moving parts friction. Also, the elimination of the need for wheels during starting/ stopping of the cars simplify car construction and maintenance. Neodymium magnet: A neodymium magnet or NIB magnet (also, but less specifically, called a rare earth magnet) is a powerful magnet made of a combination of a combination of neodymium, iron and boron -Nd2Fe14B. Neodymium magnet on a bracket from a hard drive They have replaced marginally weaker and significantly more heat-resistant samarium-cobalt magnets in most applications, due mainly to their lower cost. These magnets are very strong in comparison to their mass, but are also mechanically fragile and the most powerful grades lose their magnetism at temperatures above 176 degrees fahrenheit or 80 degrees Celsius. High-temperature grades will operate at up to 200 and even 230 C but their strength is only marginally greater than that of samarium-cobalt. Neodymium magnets (or neo as they are known in the industry) are graded in strength from N24 to the strongest N54. The number after the N represents the magnetic energy product, in mega gauss-oersteds (MGOe) (1 MGOe = 7,958 TA/m = 7,958 J/m). N48 has a remnant static magnetic field of 1.38 teslas and an H (magnetic field intensity) of 13,000 oersteds (1.0 MA/m). By volume one requires about 18 times as much ceramic magnet material for the equivalent magnet strength. The neodymium magnet i ndustry is continually working to push the maximum energy product (strength) closer to the theoretical maximum of 64 MGOe. Scientists are also working hard to improve the maximum operating temperature for any given strength. A neodymium magnet lifting 1300 times its own mass Used for stabilization and angular head motors in computer hard drives, neodymium magnets are also popular with hobbyists, and a small magnet can have amazing properties it exhibits magnetic braking when moved near a non-magnetic metal due to induced eddy currents. An excellent demonstration for students to see the effects of Lenzs Law in non-ferrous metals may be performed by dropping a strong neodymium magnet through a copper pipe. The magnet will travel through the pipe remarkably slowly as it falls, the effect may be greatly enhanced by immersing the pipe in liquid nitrogen (thus increasing its conductivity even further) prior to dropping the magnet through. A somewhat larger magnet interacts strongly enough with the magnetic field of the Earth to allow its tendency to align with that field to be perceived directly when holding it, essentially forming a compass. Cylinder- and disc-shaped neodymium magnets are especially responsive to the Earths magnetic fields. Neodymium magnets are used for the transducers in many headphones. Chapter 4 MAGLEV DESIGN 4.1 Electromagnetic Suspension System: (Concept) The design of the electromagnetic suspension system can be done with two types: 1) By using a Hydraulic Damper or 2) By using Linear Motor as a Damper. The concept is to design the magnetic suspension system on the front shock absorber of the motor bike to have a better performance with ease of handling and comfort ride. There are two cylinders installed on two separate arms of the front shock absorbing rods. The cylinder contains the pair of the cylindrical magnets having same pole facing each other to create the required repulsive force to have required levitation effect. The two cylindrical magnets having S (South Pole) on the outer surface concentric with the inner circle having N (North Pole) as shown in following figure:- 1) Working for the Hydraulic Damper: The two disc magnets in a tube or two ring magnets on a shaft, as seen in above figure comprise our required magnet for a motor bike front suspension system. With unlike poles facing, the magnets repel each other generate an air gap between them. The repulsive force restores displacement towards each other, and displacement away is restored by gravity. A hydraulic damper is fixed on the top of the cylinder and connected with the upper magnet with a shaft. The set of shocks used with magnets inside them that are used as the fork setup. One magnet is at the top of the inner portion of the shock with north polarity facing down towards the ground. The second magnet sits on the top of the inner shock that pivots up and down. This magnet has the north polarity upwards so it is parallel with the other magnet. The two magnets fight against each other giving the forks travel. There is also an adjustment at the top of the shock, which allows the magnets to become closer, together for a stiffe r travel or further apart for softer travel. The force from gravity, the force from repelling magnet the radial instability is restrained by shaft. If the shaft is removed from the simple spring, it will be unstable naturally. The magnet will tend towards vertical motion, resulting in instabi

The Awakening :: essays research papers

The Awakening In the book The Awakening, by Kate Chopin, Edna Pontellier is an unhappy, married, mother who finds an outlet from her life through a welcoming ocean. "A certain ungovernable dread hung about her when in water, unless there was a hand nearby that might reach out and reassure her."(p.27) Edna is frightened by the ocean and very overwhelmed by its massive strength. Then she learns to swim and becomes fascinated by what was once an intimidator. "How easy it is!" It is nothing."(p.27) Edna is very pleased with this new found joy; Edna is estatic over conquering her fear. "She could have shouted for joy, she did shout for joy."(p.27) Edna feels happy with herself for the first time in many years. "She felt like some new-born creature, opening its eyes in a familiar world it had never known."(p.115) Edna begins swimming regularly and thoroughly enjoys it. "Edna plunged and swam about with an abandon thrilled and invigorated her."(p.49) "She remained a long time in the water."(p.49) Swimming, for Edna, provides a much needed recess from her home life and the typical role of a woman and a wife in the 19th century. "I have a notion to go down to the beach and take a good wash and even a little swim," "before dinner? The water is too cold. Don't think of it." "Well I might go down and try-dip my toes in."(p.114) Edna is growing very fond of the ocean and so adorns her swims. No one will keep her from this new pleasure that brings such satisfaction to her life. Edna feels free for the first time since her childhood. She loves so much this mysterious new being that is so wonderful to her. The ocean proves to be a place where she can transcend her life into the life of who she wants to be. "The touch of the sea is sensuous unfolding the body in its soft, close embrace."(p.115) Edna feels closer to the sea than anyone she has ever known. "She thought of Leonce and the children. They were a part of her life, but they need not have thought they could posses her."(p.116) Edna is slowly beginning to awaken from the marriage and life that has held her comatose for so long. She realizes why she is unhappy and looks to the sea for commiseration and answers, but finds none. Edna can only continue her love affair with the ocean and appreciate her newly-discovered soulmate.

Henry Cavendish: The Shy Scientist Essay -- Science, Biography

Henry Cavendish: The Shy Scientist Henry Cavendish was born October 10, 1731 in Nice, France. His mother, Lady Anne Grey was the daughter of the first Duke of Kent while his father Lord Charles Cavendish, was second Duke of Devonshire. His ancestry links back to many of the aristocratic families in Great Britain. The chemist/physicist is most accredited for the discovery of hydrogen, the â€Å"inflammable air† and measuring the Earth’s density, but he also researched and discovered many other important scientific revolutions. Henry was described as being a very silent and solitary individual. Many called him eccentric and some believe Asperger Syndrome was the root of his behavior. He was shy of strangers and especially shy of women, so much that he only conversed with his female servants by notes. At one point he had a back staircase added onto his house to avoid his housekeeper. This shyness did not allow him to have close or personal relationships to those outside of his family. He dressed from the previous century wearing an old faded velvet coat and a three-cornered hat. When he did talk he spoke in a squeaky voice and with difficulty. His single social outlet was his membership in the Royal Society Club, in which members dined together before their weekly meetings. Cavendish rarely missed these meetings and was highly respected by his colleagues. Although admired, those who sought his intelligence were often given a response of a mumble or a vacant reply as Cavendish dashed off to find a more peacef ul area. Henry Cavendish began attendance to the University of Cambridge in St. Pete’s College on November 24, 1749 at the age of 18. On February 23, 1753, four years later, he left the university without graduating. After ex... ... the church now named Derby Cathedral and was honored by having the road he lived on named after him.

The Mormon Religion - The Church of Jesus Christ of Latter-Day Saints :: Church of Jesus Christ of Latter-day Saints

The Mormon Religion - The Church of Jesus Christ of Latter-Day Saints The Church of Jesus Christ of Latter-Day Saints, true? Not true? Christians? Not Christians? These are some of the questions people ask about the Mormon church. How did the Mormon church start? Joseph Smith Jr. was born in 1805 in Sharon, Windsor County, Vermont, to Joseph and Lucy Mack Smith. He had 10 brothers and sisters. His parents taught him to pray, read the Bible, and to have faith in God. At age 14, Joseph saw God the Father and His Son, Jesus Christ, in his First Vision. At age 17, Joseph began to receive heavenly messengers who prepared him for his role in the Restoration of the Church of Jesus Christ to the earth. He was a prophet, just like those in biblical times. The First Vision As a boy, Joseph Smith was surrounded by various churches which each claimed to teach the truth. This caused him much serious reflection. He wanted to know which church was right. One day he read a passage in the Bible which says, â€Å"If any of you lack wisdom, let him ask of God, that giveth to all men liberally, and upbraideth not; and it shall be given him† (James 1:5). Joseph decided to accept the invitation to ask God.(James 1:5) 5 aIf†¢ any of you lack bwisdom, let him ask of God, that cgiveth to all men liberally, and dupbraideth†¢ not; and it shall be given him. In the spring of 1820, Joseph went to a grove of trees near his home and prayed to learn which church he should join. In answer to his prayer, Heavenly Father and His Son, Jesus Christ, appeared to him. Joseph wrote: â€Å"When the light rested upon me I saw two Personages, whose brightness and glory defy all description, standing above me in the air. One of them spake unto me, calling me by name and said, pointing to the other—This is My Beloved Son. Hear Him!† Joseph was told to join none of the churches that existed at that time. Joseph’s written account of this event is a powerful testimony of what he saw and experienced. Joseph’s written account After I had retired to the place where I had previously designed to go, having looked around me, and finding myself alone, I kneeled down and began to offer up the desires of my heart to God. I had scarcely done so, I saw a pillar of clight†¢ exactly over my head, above the brightness of the dsun†¢, which descended gradually until it fell upon me.

Gmf (Genetically Modified Food) Essay

â€Å"Genetically modified foods† is the term most commonly used to refer to crop plants created for human or ani mal consumption, which have been modified in the laboratory to enhance desired traits or improved nutritional content. The enhancement of desired traits has traditionally been undertaken through breeding, but conventional plant breeding methods can be very time consuming and are often not very accurate. Genetic engineering, on the other hand, can create plants with the exact desired trait very rapidly and with great accuracy. Development. GM foods were first put on the market in the early 1990s. Typically, genetically modified foods are plant products: soybean, corn, canola, and cotton seed oil, but animal products have been proposed. The first commercially grown genetically modified whole food crop was the tomato puree (called FlavrSavr), which was made more resistant to rotting by Californian company Calgene. Currently, th ere are a number of foods of which a genetically modified version exists. What plants are involved? Some foods have been modified to make them resistant to insects and viruses and more able to tolerate herbicides. Crops that have been modified for these purposes, with approval from the relevant authorities, in a number of countries, include: maize, soybean, oilseed rape (canola), chicory, squash, potato. Some of the advantages of GM foods: There is a need to produce inexpensive, safe and nutritious foods to help feed the world’s growing population. Genetic modification may provide: ï‚ · Better quality food. ï‚ · Higher nutritional yields. ï‚ · Inexpensive and nutritious food, like carrots with more antioxidants. ï‚ · Foods with a greater shelf life, like tomatoes that taste better and last longer. ï‚ · Food with medicinal benefits, such as edible vaccines – for example, bananas with bacterial or rotavirus antigens. ï‚ · Crops and produce that require less chemical application, such as herbicide resistant canola. Some of the disadvantages of GM foods: Food regulatory authorities require that GM foods receive individual pre-market safety assessments. Also, the principle of ‘substantial equivalence’ is used. This means that an existing food is compared with its genetically modified coun terpart to find any differences between the existing food and the new product. The assessment investigates: ï‚ · Toxicity (using similar methods to those used for conventional foods). ï‚ · Tendency to provoke any allergic reaction. ï‚ · Stability of the inserted gene. ï‚ · Whether there is any nutritional deficit or change in the GM food. ï‚ · Any other unintended effects of the gene insertion. Economic concerns: Bringing a GM food to market is a lengthy and costly process, and of course agri -biotech companies wish to ensure a profitable return on their investment. Many new plant genetic engineering technologies and GM plants have been patented, and patent infringement is a big concern of agribusiness. Yet consumer advocates are worried that patenting these new plant varieties will raise the price of seeds so high that small farmers and third world countries will not be able to afford seeds for GM crops, thus widening the gap between the wealthy and the poor. One way to combat possible patent infringement is to introduce a â€Å"suici de gene† into GM plants. These plants would be viable for only one growing season and would produce sterile seeds that do not germinate. Farmers would need to buy a fresh supply of seeds each year. However, this would be financially disastrous for farmers in third world countries who cannot afford to buy seed each year and traditionally set aside a portion of their harvest to plant in the next growing season. How are GM foods labeled? Labeling of GM foods and food products is also a contentious issue. On th e whole, agribusiness industries believe that labeling should be voluntary and influenced by the demands of the free market. If consumers show preference for labeled foods over non -labeled foods, then industry will have the incentive to regulate itself or risk alienating the customer. There are many questions that must be answered if labeling of GM foods becomes mandatory such as; are consumers willing to absorb the cost of such an initiative? If the food production industry is required to label GM foods, factories will need to construct two separate processing streams and monitor the production lines accordingly. Farmers must be able to keep GM crops and non -GM crops from mixing during planting, harvesting and shipping. It is almost assured that industry will pass along these additional costs to consumers in the form of higher prices. Food labels must be designed to clearly convey accurate information about the product in simple language that everyone can understand. Conclusion: Genetically-modified foods have the potential to solve many of the world’s hunger and malnutrition problems, and to help protect and preserve the environment by increasing yield and reducing reliance upon chemical pesticides and herbicides. However, we must proceed with caution to avoid causing unintended harm to human health and the environment as a result of our enthusiasm for this powerful technology.

The Millers Prologue And Tale Analysis English Literature Essay

Geoffrey Chaucer was a mediaeval author and regarded as the greatest of Middle English authors. Born in London, Chaucer was the boy of a affluent merchandiser who sent him to be trained at a baronial family. There he was educated and began to take journeys along with the male monarch for concern. Chaucer was a really busy man of affairs, and in his trim clip he would compose. He wrote The Canterbury Tales, during the fourteenth-century, a fabliau, which was about a group of people stating their narratives on a pilgrim's journey to the Canterbury Cathedral. The Miller ‘s tale mirrors today ‘s stand-up comedy modus operandis as evident in the Miller ‘s usage of timing, sarcasm, and personal narratives to state his narrative. † A TheA Millers Tale started by speech production of John, a carpenter, and an older gentleman, and his immature married woman, Alison, an 18 twelvemonth old adolescent. He loved her more than he loved himself. John was described as being covetous, because of her age, thereby maintaining her caged. In actuality, he was good hearted and really naA?ve. He was a typical older adult male that merely wanted to work hard and love his married woman. Alison was described as â€Å" wild and immature, with a slender, graceful organic structure † . Today there are older work forces that marry younger adult females, but normally non at such a immature age. John loved his married woman more than himself and most work forces today, who are attracted to immature adult females, are really in love and naA?ve every bit good. Alison was in love with a immature adult male that happened to be her and her hubby ‘s roomie. She was n't in love with John, yet she knew that he would make anything fo r her. At such a immature age, it sounds like she wanted what adult females in today ‘s society, would name a â€Å" sugar dada † , person to give her nutrient, shelter, money and demo her echt love. Nicholas was a clerk, and he was besides John and Alison ‘s roomie. He was immature, wild and a con-artist. He was besides, in love with Alison. Although he ne'er truly described her as did the other characters, the Miller made it evident of his fondness for her. His function in today ‘s society could be compared to a wild college pupil at an Ivy League university. He did n't mind a challenge and finally played the biggest function in the Tale because he plotted a fast one in order to pass clip with the adult female that he loved. He could read people good because he conjured up a program that worked ab initio, to flim-flam John so that he could pass the dark with Alison. He pretended that something was incorrect with him and being naA?ve, John believed him. He spoke about a major inundation and had John hanging bathing tubs. They all got in the bath until John had fallen asleep in the bath, so Alison and Nicholas snuck off to be together. While I do n't cognize anyone in today ‘s society that would travel this far, the play with Nicholas and Alison reminded me of a daytime soap opera sing they would crouch so low as to do up this narrative, and prosecute sexual brushs in Alison ‘s hubbies sleeping room. The last character in the narrative, Absolom, was besides a clerk and in love with Alison. Absolom was â€Å" reasonably and homosexual † , and day-dreamed about Alison. He described her as â€Å" spare, and so sweetly lecherous † . Like John, he was infatuated by Alison. Alison mentioned that â€Å" Absolom is populating in a bubble. He has nil but a laugh for all his problem. † It appeared that he did n't hold a hint about adult females and had ne'er dated before, but was happy merely being allowed to talk to Alison and lavish her with vocals, money and gifts. Today, there are many immature work forces like Absolom, who in secret loves a beautiful adult female but think they have no existent opportunity on holding her so, settle on woolgathering alternatively. The sarcasm of this character is that he was so clueless that he ended up blowing the screen of Nicholas and Alison ‘s love matter by firing Nicholas ‘s butt. I would state that things like th is as it relates to today ‘s society, happens when there is a sloppy deceiver, sloppy things come to visible radiation! Although there was no moral to the narrative, throughout the narrative, each character could be compared to in some facet, with people in today ‘s society. I believe the writer ran across aliens during his travel, and to maintain himself entertained, found ways to compose about these different people and utilize it for his ain ego pleasance. Possibly his occupation was so serious that he had to do visible radiation of any given state of affairs. The writer could hold really good encountered most of these people throughout his life. We will ne'er cognize what his logical thinking was, but it ‘s astonishing to see that people today are still like they were in some facet to the people in the in-between ages. The writer used timing, sarcasm, and personal narratives to maintain people interested, yet it is so closely related to today ‘s society.

Data Collection Method

the researcher used Quantitative data collection methods. Using qualitative data collection method, it rely on random sampling and structured data collection instruments that fit diverse experiences into predetermined response categories. They produce results that are easy to summarize, compare, and generalize. Quantitative research is concerned with testing hypotheses derived from theory and/or being able to estimate the size of a phenomenon of interest. Depending on the research question, participants may be randomly assigned to different treatments.If this is not feasible, the researcher may collect data on participant and situational characteristics in order to statistically control for their influence on the dependent, or outcome, variable. If the intent is to generalize from the research participants to a larger population, the researcher will employ probability sampling to select participants. From this research, the researcher used questionnaires and surveying technique in co llecting data. In the surveying techniques, it involves direct questioning of respondents about price.The researcher can choose whether to present the respondent with a range of possible prices, or force a response with no point of reference other than the concept and the question. While, for the questionnaires, researcher used the Web based questionnaire and structured questionnaire. By using web based questionnaire, it is the use of Internet based research. This would mean receiving an e-mail on which would click on an address that would take to a secure web-site to fill in a questionnaire. This type of research is often quicker and less detailed.People might be in a hurry to complete it and so might not give accurate responses. In this research ,researcher used of 2500 questionnaires mailed. While, for the Structured questionnaire, it is the structure of the individual questions requires respondents to qualify their price based on an implied assumption about quality. The structur e of the individual questions also was designed to capture consumers’ willingness to pay more for the five common wood products, given environmental certification.Respondents were given a non-certified price for each of the five products and asked to identify the price they were willing to pay for an environmentally certified product. DATA ANALYSIS TECHNIQUES Researcher have analyzed their data using data analysis techniques. Data analysis techniques that stated in this research includes, factor analysis, correlation, ANOVA, Chi Square, and descriptive statistics. Factor analysis( maximum likelihood with varimax rotation) was conducted on 20 items. This resulted in a reduction to five underlying factors.The factors were subjected to scale testing with resulting Cronbach alpas ranging from 0. 62 ( involvement in Certification) to 0. 90(importance of Certification). Correlation analysis . Correlation analysis is used by the researcher to test the relationship between factored. All hypothesized relationships were found to be significant and all but one was found to be directionally as hypothesized. Price was found to be positively correlated to consumer willingness to pay for certified wood products, the inference being that consumers perceive incremental value in certified products.ANOVA . Analysis of Variance (ANOVA) is a data analytic technique based on the idea of comparing explained variance with unexplained variance, kind of like a comparison of the coefficient of determination with the coefficient of alienation. It uses a rather unique computational formula which involves squaring almost every column of numbers. ANOVA techniques was used to test the hypotheses of no difference between the cluster means in this research. Chi square.In this research, researcher used chi square. A technique designed for less than interval level data is chi-square and the most common forms of it are the chi-square test for contingency and the chi-square test for indepen dence. The chi-square test for contingency is interpreted as a strength of association measure, while the chi-square test for independence (which requires two samples) is a nonparametric test of significance that essentially rules out as much sampling error and chance as possible.In this research it used chi square for the purpose of compared consumer segments on selected demographic characteristics. The consumer segments compared on selected demographic characteristics includes democrat, and environmental group member. Descriptive statistics. Descriptive statistic used in this research to measures of central tendency of mean. Examples include descriptive analysis of age, gender, education level, income level, republican , political view, democrat and environmental group member.
