Heat Transfer Design Project HOT Gantry Crane Research Paper

Heat Transfer Design Project HOT Gantry Crane - Research Paper Example In the current setup of the electronics package, the heat generated by the transistors can only be lost through air convection. The temperature of the devicessurrounding, therefore, needs to be less than the allowable temperature of the device. At 150 degrees Celsius, the device is prone to damage. The introduced heat sink will however try to reduce the junction temperature for the device and ‘dump’ it in the surrounding media. Electronic device uses air as a medium.In a transistor; there exist connections between the casing and the junction and from the case to theheat sink. In addition, the contacts between the device and the sink usually contain a thin film, which, therefore, affects the heat transfer. All these features cause a temperature differential. They act as thermal resistances and usually each thermal resistance has a coefficient number always unique for each case and is expressed in temperature per watt. Because of this, there develops temperature difference s between the collector junction and the ambient. This particular variable should however be kept at a minimum 1) Rearranging the transistors- In the current layout, the transistors are stacked together. This contributes to theaccumulationon heat thus increase in temperature. This proposed design will consider arranging the transistor and having some gap between them. The spacing ensures free circulation of air and heat loss from the transistor surfaces. The material commonly used for heat sinks is aluminium with some fins fitted for more effective heat dissipation. The fins increase the surface area over which heat dissipation takes place.Since thecostis a major factor; the ultimate choice for this design will be aluminium. The sink chosen have should have a flat surface to enhance good physical contact. This will ensure maximum heat transfer. Grooves that match the transistors contact will be createdon the heat sink block. The heat sink will be fixed together with a

BMW i Marketing Analysis - Essay Example It tends to focus upon zero emission and is presently working on a hydrogen hybrid drivetrain. It can be noted that most of the success of the BMW is derived from the entrepreneurial culture. BMW follows informal organisational culture which assists the employees in freely articulating the ideas and thereby assisting in innovation (BMW, 2012). The main objective of the company is to remain as one of the world’s primary providers of premium products as well as services for mobility of an individual. Collaborators BMW has been capable of maintaining good relation with its suppliers so that the goods can be delivered on time to the customers. The company mandates its suppliers to maintain the enhanced environmental as well as social standards that have been set by the BMW Group (BMW Education, 2010). It is because of this reason that the company makes use of the sustainability criteria in the optimum selection of its vendors and exaggerated supervision of its prevailing suppliers . It tends to train its suppliers in advance so that the company can guarantee accurate quality requirements as well as standards that have been set by the company right from the initiation of the production (The Economist, 2011). It has been found that in 2011, the UK car market was high by approximately 30% on a year-to-year basis which exceeded the expectation of the companies. In January, 2011, it was found that the car market rose by almost 29.8% thereby reaching 145479 units. It has been found that in the year 2011, an increase occurred of 8.78 percent in sales that rose from 153312 to 166780 vehicles in comparison to the year 2010, and against the market that sought decline in the sales by four percent (Boeriu, 2012). It has been evident that BMW makes use of three steps for the purpose of targeting such as market segmentation, target choices and product positioning. The company looks at behavioural, geographic, socioeconomic, beneficial and demographic features of the societ y that assist them in targeting the market effectively (Pearson, 2012). The company derives 65% of its sales from Europe as well as North America. These regions are industrialised locations with residents having sound financial position to purchase upper market cars since their per capita income is high. The demographics of the people capable of purchasing BMW are men and women who are aged 30-50 years old. Prior to purchasing BMW, people possess favourable image in their mind. They prefer cars that look sporty and modern. The benefits sought by these people are reliability, superiority, quality and performance (Slideshare, 2012). Competitor Analysis It has been found that the company faces direct competition for its each series ranges. The main competitors of the company are Mercedes, Audi, Volkswagen, Ford, Range Rover and Porsche among others. Among them, Ford Motor Company is found to be the main competitor of BMW, taking away high share of the automotive market. It has been obs erved that the overall balance sheet value of Ford Motor Company tends to surpass 7 times ‘correspondent value’ of BMW Group (BMW Limited, 2011). Climate In the present times, the political

The most important lessons Catholic school principals should draw from Essay

The most important lessons Catholic school principals should draw from the history of Catholic Church - Essay Example The principals should understand that the most important task of any Catholic School is to maintain continuous strength of the schools. The history of Catholic Church gives out the important lessons that the principals should be aware. Such lessons are; the school should be sustained by gospel witness, have supernatural mission and vision, founded on Christianity, animated by communion and community, and filled with Catholic principals throughout. This essay gives an outline of all these five important lessons that Catholic School Head teachers should be familiar. Supernatural Vision The Catholic Church terms education as the process of transforming children to fix their eyes on heaven. The major purpose of Catholic Church education is to educate students to be good citizens and God-fearing ones. Therefore, the Schools’ Principals should ensure that they produce citizens who have good morals and follow the will of Almighty. Catholic Schools, unlike other institutions such as Government, business, and media, which view education as an instrument for acquisition information to students to improve their living standard and chances of worldly success, Catholic Churches’ vision of education is to help student improve their moral behaviors, be God loving, and become saints of the world to come. Christian Anthropology Foundation The Catholic Churches emphasizes on Supernatural destiny of students meaning that schools should perfect all students to become good images of God. The Catholic history describes that graces depends on the nature of the human beings. Therefore, the Principals should be aware that Catholic School educators should be able to understand the human person. The educators should have both natural and supernatural power of perfection of the students under their care (Stewart, 2008:212). However, the Catholic history emphasizes on schools educational philosophy built on a proper understa nding of what human person is. All the Catholic School educators should teach his lessons with Christianity concept. Therefore, Catholic Schools, unlike other public schools is not a factory of teaching skills to fulfill the skill requirement for business and industry, and must be founded on Christian Anthropology. Animated on Communion and Community According to Catholic History, a school is a community of persons and faith. Due to this emphasis, Catholic Schools are different from public schools and roots to the nature of human being and church reality. Therefore, catholic schools are educational community. Schools' Principals should be aware that Catholic schools are as a community according to the church Council (Stewart, 2008:121). The dimension of this community is a theological perception rather than sociological group. Catholic History defines school in four areas: teamwork of the involved, educators and bishops’ cooperation, teacher-students’ interaction, and physical environment of the school. The principal should ensure that the school adheres to all these aspects for a smooth running of the schools. Schools should be always imbued with Catholic Worldview One of the key factors of a Catholic school is the permeation of Catholicism spirit throughout its curriculum. According to Catholic history, the purpose of education in school is to perfect growth of the students. Education has the main purpose of developing students’ capability by improving his or her physical, psychological, moral standards, and religious capabilities (Stewart, 2008:293). In order for the school to produce integral students, it must have gospel guidance. Therefore, the principals should ensure tha

Advanced Nursing Role - Essay Example elly (2012) front line managers are responsible for patient care delivery, planning and monitoring resources, maintaining codes and standards and developing and evaluating staff. Middle-level managers facilitate cooperating in the organization by serving as a link between front line and upper-level managers. Upper-level managers are specialized in management and administration of the healthcare organization; by establishing goals and strategizing plans (p. 401). I agree that nurse managers and nurse administrators have supervisory tasks in an organization. Even though individuals sometimes regard a nurse administrator and nurse manager as one administration role, it should be noted that these two roles differ in responsibility and payment. Nurse Managers are responsible for a single unit within a medical facility, while a nurse administrator is responsible for more than one unit all units in a medical facility. Additionally, nurse managers fall under the category of middle management, while nurse administrators fall under executive level management (Crowther, 2008). In regard to educational level; nevertheless, they can possess a graduate degree as an added advantage; while nurse administrators require a graduate degree as well as clinical experience. Nurse Managers work directly with nurses who offer primary care to patients, giving guidance on the appropriate medical care, whereas nurse administrators work with middle-level managers and other senior staff, thereby providing indirect care to patients (Parker & Smith,

Marketing - Essay Example Balancing marketing mix enables the business to deliver its product in the right location within the stipulated time. Firms that demonstrate great consumer satisfaction are able to hold on large market shares because they respond effectively to consumer trends. Introduction Sustainability of an organisation depends on economic viability of the business in relation to customer’s behaviour. Business enterprises that post successful results in the market are able to convince consumers to buy their products as well as reciprocating consumer’s behaviour by providing products, which will satisfy consumer demands. Zara is an apparel company with outlets in famous cities of the world. The organisation traces its root in Spain; however, it has branches in major cities of the world. The concept that this paper intend to discuss is marketing of the company product. Marketing is a crucial element for the business because it dictates the viability of the sustainability of the busine ss. The report will explore various marketing aspects such as customer, market environment, and marketing mix in relation to the strategy of the business. Investigation of the above aspects will enable the report to make recommendation as well as developing future strategies of increasing the performance of the business. The operation of the company in foreign markets is a concern of this paper. The choice of market is very critical to the business performance. However, the knowledge of customer choices helps many enterprises to integrate their markets with respect to consumer behaviour. Zara The firm established its operation in 1975 in Galicia Spain. The firm has stretched its operation to cover large cities in the world. It retails products of textile with a focus on fashion trends that dictate the consumer behaviour in the clothing industry. The profit margin of the organisation has been consistently high, demonstrating that the organisation is economically viable. Currently, th e organisation has 2,692 stores across the world (Dutta, 2002:3). The organisation’s aim is to feed the markets with medium quality products at competitive prices. The idea is to ensure that the company products are selling in a highly competitive environment. The organisation relies on consumer trends in designing its products as well as setting the prices of the product. Clothing apparels pose a number of challenges to entrepreneurs because the consumption behaviour changes with fashion trends (Luo, 2008:6). This requirement dictates the marketing strategy of the product. For instance, the organisation has observed that high prices delay stock turn over which eventually reflects on the profit margin of the organisation. Zara’s manufacturing and stocking trend ensures that the customers’ tastes are available in the market at any given time. The idea seems to be influencing the manufacturing trends developed by the firm. Time is a concept that influences product behaviour in most cases. Some product have short expiry period while other have long expiry period. Whatever the case, market response for the company product dictates the manufacturing speed and the profit of the business. For example, Y products in the market may take two months in the market. The two months would be reflecting on the product demand patterns demonstrated by the consumers. However, when the organisation decides to change the prices of the

Financial crisis regulatory Essay Example | Topics and Well Written Essays - 2000 words

Financial crisis regulatory - Essay Example Robert Shiller examined the controversy of the global economic crisis and its management and raised prudent arguments about the practice. The economist argues that democratization of finance provides an ideal strategy of managing the contemporary and future economic crisis. Some analysts support Shiller’s perspective while others have criticized his ideology. Interestingly, few economists argue that the financial regulations adopted by the OECD countries are sufficient in containing financial crisis (Gray & Akseli, 2011 p. 2). Considering the magnitude of the idea of global financial crisis management, there is a need of developing knowledge of ideal approaches of managing the problem. This article provides an analysis of the debate started by Shiller concerning democratizing finance while comparing the argument with the types of regulatory measures practiced by the OECD countries. The Shiller’s perspective on financial crisis Shiller explores the importance of moral re putation of finance institutions in management of economic crisis. After the 2008 global economic recession, anger expressed itself in objections around the world. People constantly criticized how powerful profit oriented social-economic procedures have influenced financial institutions. The Occupy movement staged serious actions challenging the relationship between the government and businesses. A clear insight was that individuals responsible for the crisis would revitalize their moral reputations by adopting acceptable financial procedures (Kroszner, Shiller & Friedman, 2011 p. 4). Shiller has popularized an idea that economists need to reclaim the finance for the common good instead of condemning it. He argues that finance is a powerful tool that the society can utilize in solving its problem and in developing its general welfare. The global economy needs more finance but not less and the finance should facilitate the attainment of the society’s goals (Tropeano, 2011 p. 5 ). Consequently, the analyst emphasizes the need of rethinking about finance and its responsibility in the society. Particularly, Shiller claims that financial management should not merely include the manipulation of money or control of risks but should mainly involve the stewardship of community’s assets. The economist highlights how individuals serving in the financial careers can manage, safeguard and increase the public assets. Moreover, the analyst explains how finance has contributed to the good of the society through inventions, savings accounts, mortgage and pensions. Consequently, Shillers insists that economists and policy makers should devise new strategies for rechanneling financial creativity to benefit global economies (Princeton University, 2012 p. 1). Previous regulations schemes have targeted restricting the financial sector by slowing down the development of lending or trading. However, Shiller’s alternative believes that this ideology is unproductive especially in the current dynamic industry that presents high degrees of dynamism. The Shiller’s model values the importance of creativity, personal morality, education and effect of finance on the people’s lives (Princeton University, 2012 p. 1). Shiller supports the present financial regulation system arguing that although the system is imperfect, it plays a significant role in stabilizing the global economy.

Breastfeeding vs Formula Essay Example for Free

Breastfeeding vs Formula Essay Deciding whether to breastfeed or provide formula milk is a major decision amongst new mothers. As simple as it may seem, the decision to breastfeed versus formula feed babies can be difficult and one of the most important decisions a mother can make. While there is nothing wrong with giving babies formula milk, breastfeeding should be the number one choice for mothers. As breast milk provides more nutrients, is naturally produced by mothers and is less expensive, breastfeeding is more beneficial than formula milk. When examining the benefits of breastfeeding as opposed to formula milk, breast milk tops the list with the nutrients and antibodies it provides. As breast milk contains antibodies that formula milk does not, this provides extra protection for babies against diseases and viruses. The first milk a baby receives while breastfeeding is colostrum. Colostrum is rich in nutrients and the mother’s own disease-preventing antibodies which may protect the baby from certain viruses (Kutner, 2012). Thus, breastfeeding babies contribute to building babies’ immune systems. As the breast milk matures, â€Å"the cells, hormones, and antibodies [in breast milk]†¦protect babies from illness† (Womenshealth. gov, 2011). This combination is unique to breast milk and is not contained in formula milk. On the other hand, some formula milk does contain more vitamin D than breast milk, which is essential in building strong bones. In addition, formula milk also contains fluoride which is important for healthy teeth. However, both nutrients can be provided to babies as a supplement if they are needed. Formula milk does not contain the antibodies that breast milk has which contributes to a healthier, less sick baby. Breast milk is produced naturally by mothers and is designed especially for babies whereas formula milk is manufactured. Since breast milk is unique to each mother and child, there is no worry about the baby having an allergic reaction to the milk or not able to consume it. Unlike manufactured formula milk, breast milk also decreases allergies some babies develop from being exposed to allergens from other milk products. â€Å"By postponing the introduction of allergens into the child’s body until they are more mature, the risk of them developing an allergy is significantly reduced† Netdoctor pg. ( 30-04- 2010). In addition, breast milk is also easier for babies to digest than formula milk. As the mother’s milk matures, it contains a natural balance of fat, sugar, water and protein to help [babies] continue to grow (U. S. Department of Health and Human Services Office on Women’s Health, 2011). Because breast milk is easier for babies to digest, breastfed ba bies are less likely to experience constipation and other gastric irritations as opposed to babies that are fed formula milk. On the other hand, since it takes longer for formula milk to digest, babies could go a little longer between feedings. However, mothers face a bigger risk of having a fussy baby because of gas and constipation as a result of the difficulties babies may have digesting the formula milk as opposed to the easier digested breast milk. Since breast milk is produced by mothers, there is a less likely chance of contamination than formula milk. Formula milk is manufactured, which leaves room for the formula milk to get contaminated by different bacteria that can be very harmful to a baby. Bacteria such as Salmonella can unintentionally get in manufactured milk and cause serious health issues for babies. In addition, there is no real way of knowing what products are used to make formula milk. Pat Thomas (2006) states, â€Å"Formula may also contain unintentional contaminants introduced during the manufacturing process. Some may contain traces of genetically engineered soya and corn. † Even though the package may list the main ingredients, there are other things used that may be unknown. By breast feeding, mothers have a greater control of what enters their babies’ body. As breast milk is produced naturally by mothers, breastfeeding is less expensive and more convenient for mothers than formula milk. Since the breast milk is produced by mothers, it is a free source of milk as opposed to the cost associated with buying formula milk. The cost of formula averages between $1,000 and $1,500 for the first year of a baby’s life. Schoenstad pg. 1 (31-07- 2009) Since a mother is breastfeeding, the need for bottles and nipples is not as high as opposed to the requirement of having bottles and nipples in order to feed babies formula milk. In addition, since breast milk contains antibodies that promote healthier babies, medical bills are lower. Breastfeeding is also more convenient for mothers as opposed to feeding babies formula milk. Unlike formula milk, mothers do not have to worry about measuring, mixing and warming the milk before feeding their babies. The breast milk is right at hand when it’s needed. Even for working mothers, they are able to pump the breast milk and store for a later time. Since the milk is already prepared, there is less worry that others may not mix the baby’s milk correctly. Breastfeeding also provides time for mother and baby to bond while allowing the mother to relax. On the other hand, feeding babies formula milk, allows others the opportunity to feed the baby while taking the pressure off of mom. Lawrence Kutner (2012) states, â€Å"One of the advantages of [formula]-feeding is that it allows fathers to spend more time caring for their baby†. However, mothers can pump and store breast milk to allow fathers and other relatives feeding time with the baby. Thus, by breast feeding as opposed to providing formula milk, mothers are able to save money while also saving time. In conclusion, as breast milk provides more nutrients and antibodies, is naturally designed for babies, cost less and saves times, the benefits of breastfeeding outweighs formula milk. The nutrients and antibodies produced in breast milk contribute greatly to a healthier baby. Because breast milk is produced naturally, it is designed especially to meet the baby’s needs and is readily available. Mothers do not have to worry about the high cost of formula milk and spend less time measuring and mix milk. As mothers breastfeed their infants, a bond is developed that outweighs any advantages formula milk provides. ?
