The Beauty of Color Essay -- Creative Writing Essays
As the car stopped, he caressed me immediately; in synch with the stopping of the engine was the start of us. I say us because I feel like thatââ¬â¢s what it is to become intimate with someone, you merge, mesh, mix into some form of a united being. I enjoyed him. Intimacy was an act of passion. It didnââ¬â¢t take love to feel passion, and it didnââ¬â¢t take an appropriate union to become a part of another person. We were one as he kissed me, touched me. I felt him and he felt me. One. ââ¬Å"You like that,â⬠he said, panting like some needy animal. Please be quiet. ââ¬Å"Say it if you like it,â⬠he panted some more. Shut the hell up. ââ¬Å"Is it good?â⬠ââ¬Å"Quiet!â⬠I yelled without realizing that my thoughts were vocalized. He pulled back and stared at me as if I were some whacko, needless to say the look was returned. A quick awkward expression and a not so melodious cry ended the moment. Now, the only sounds we heard other than the heavy breathing of us both was the zooming of passing vehicles. As I licked over my dry lips I recognized the taste of sweat in my mouth, kissing his neck I guessed. As he got up and scooted to ââ¬Ëhis sideââ¬â¢ of the van I scratched my head noting that my hair felt like shit. Relaxed hair need not get sweaty; I felt the naps I tried so hard to conceal creeping back into the roots of my follicles. No ââ¬Ëgoodââ¬â¢ hair here. His eyes were closed and I could see the moon reflecting light off of his caramel-complexioned skin. I got up and moved, naked, to the front of the van to roll down the windows; the dankness of the vehicle was enough to make me gag. ââ¬Å"When are you going to take me home?â⬠I asked. Without opening his eyes he shrugged his shoulders and gestured for me to shut up. ââ¬Å"I would like to get back before my show... ...ooks, Paw-Paw was the only person in the world to ever call me beautiful. *** ââ¬Å"You are not like me.â⬠I said plainly. I opened my eyes to see that he was no longer listening. One thing about us, we connect during intimacy, but other than that we play tag. I want to tell him, though. Shake him and explain that his color makes me squirm. The way others of his ââ¬Ëpaper-bag-brownââ¬â¢ have talked down to me, made me question myself. Tell him that it took years to reverse the hatred that I grew for myself. I was eager, wanting to spill it all to him, make him understand. But I mellowed out. Looking at the moon on his skin I just pulled him towards me into my shadow, my dark shadow. Instead of telling him how I felt I would show him. Show him my hatred, my love, my curse, and my blessing. And in that van, in the dark of my shadow, we were both as black as we wanted to be.

Rokeby Venus Essay -- Essays Papers
Rokeby Venus I choose to look at the painting ââ¬Å"The Toilet of Venusâ⬠or more commonly referred to as ââ¬Å"The Rokeby Venusâ⬠by Diego Velalazquez. The ââ¬Å"Rokebyâ⬠part came into effect, because the painting was originally displayed in the Morritt Collection at Rokeby Hall in Yorkshire, before being moved to its current home in the National Gallery. Diego Velazquez was born in Seville in 1599, and went on to become one of the most brilliant and influential painters ever to come from Spain. He lived in Madrid for most of his adult life, and was employed as a court painter. Throughout his career, he tackled a wide variety of subjects, such as landscapes, scenes from real life, and mythological/religious figures. He was a master realist who excelled at capturing essential features upon the canvas. He painted ââ¬Å"The Rokeby Venusâ⬠between 1647 and 1651, and was his only nude portrait, as well as the first one in Spain, at that time. Initially the painting me t with some disapproval, especially from the Church, since it was a nude, but eventually the work received great praise, and became known, as being one of the most beautiful and significant portrayals of Venus in the history of Western Art. The painting, in its simplest form, consists of a naked woman lying elegantly upon stately and rich cloths, while a young, also nude boy, is holding a mirror which contains her reflection. Upon first glance of this work, I was quickly able to make out the identity of the two subjects. ...

Historical Perspectives in Special Education Essay
Autism Spectrum Disorder There are many different definitions for the term special education. An effective definition for special education is that its specialized instruction that students with disabilities are entitled to receive as articulated in IDEA, (Friend, M). There are many different disabilities that can entitle a student to special education. Students are entitled due to learning disorders, mental retardation, physical disabilities, and also disorders such as autism. In this paper I will discuss doctors, schools, and educators that has had made a difference in the life of a student with autism. Born, February 18, 1906, Hans Asperger was an Austrian pediatrician that published the first definition of Aspergerââ¬â¢s Syndrome in 1944. Asperger did a study on four boys and acknowledged a pattern of behavior and abilities that he called ââ¬Å"autistic psychopathyâ⬠. The word autistic means self and psychopathy means personality disease. According to Asperger, the pattern included a lack of empathy, little ability to form friendships, one-sided conversations, intense abruptions in a special interest, and clumsy movements. Children with Aspergerââ¬â¢s Syndrome had the ability to discuss their favorite subject in great detail and for that reason Asperger often called them ââ¬Å"little professorsâ⬠. Asperger passed away October 21, 1980, before the identification of this pattern of behavior became widely recognized. Today, technology plays a major role in the life of a student with ASD such as the software Mind Reading, which helps them cope with the disorder ASD and learn different skills daily. Mind Reading is a software that covers the entire spectrum of emotions, and is suitable for the ages of 5 through adult hood. Using the software can help a student explore over 412 emotions, allowing them to hear the emotions by six different people. Mind Reading also provides context, there are 2472 faces, voices, and stories about emotions. Mind Reading is inexpensive for its value. Parents can purchase Mind Reading for $129 for the DVD that contains the emotions library module, games zone, and learning center modules. This DVD can also be run on computers. There is a more expensive software starting at $499 that would be used for classrooms. This device is the DVD with Site License. This package contains 4CDROM disks that are used to install the product directly to the hardware. Mind Reading software can be helpful to a student with ASD in a classroom, by helping them learn their emotions and how to cope with them. This software allowing them to hear so many voices, see so many faces, and hear many different stories gives them the knowledge that they are not the only oneââ¬â¢s feeling those different emotions. Aside from the Mind Reading software, there are also different institutions that are helpful to students with ASD and tend to their emotions. There are places such as the New England Center for Children thatââ¬â¢s available to students with ASD. NECC has twenty-five years of practical experience. Located in Massachusetts, it is accessible to students with ASD from all over. NECC has a commitment to respectfully provide high quality educational services, and to help each student to reach his or her individual potential and to lead a productive and independent a life as possible. NECC offers several services such as academic, speech and language therapy; development of social and life skills, vocational training, physical education, occupational therapy, family services, outreach services and health care. Independence is strictly emphasized at NECC. There are schools such as Heartspring that serves children with various disabilities as well as schools such as Pacific Autism Center for Education that has residential group homes. Parents may prefer to send their children to a school that serves children with ADS versus an inclusion classroom, because their needs are specifically identified at a school for ASD. Inclusion classrooms are great for social skills but it can cause confusion when it comes to there needs being met. Schools are not the only supporters of ASD; there are also several agencies that serve students with ASD. Bernard Rimland founded the Autism Society of America (ASA) in 1965. ASA is dedicated to increasing public awareness about autism and the day-to-day issues faced by individuals with autism, there families and the professionals they interact with. ASA and its chapters share a common mission of providing information and education as well as research and advocating for programs and services for the autism community. An important service that ASA provides is valuable peer support. Peer support is valuable because it brings together parents and families who are dealing with the same emotions as the others; rather they are joyful or painful. Overall, I believe that if Hans Asperger was still alive today he would be actively involved in the different organizations and agencies providing services for students with ASD. The study that Hans Asperger did has increased in knowledge and if he was still alive today he would have contributed to the study done and correct the assumptions done by society. If Hans Asperger could send a message to me a future professor, it would probably say to be patient with the students with ASD and to take the time to try and understand them. Hans story has inspired me as a future teacher because he watched two young children and noticed something different in them. With what he noticed he did a study and found interesting facts that nobody else ever noticed. That alone has been an inspiration, and a note to me to watch your students and notices there differences it could have a special meaning behind it. Works Cited ASA, The Voice of America. (2004).

Company Analysis of Nike 2014 Essay
INTRODUCTION/ COMPANY BACKGROUND This report examines NIKE Inc. one of the leading sports brand in the world. It uses business analysis techniques such as SWOT, PESTEL, Porterââ¬â¢s five forces, and Ratio analysis to analyse the business environment and performance of this company. NIKE Inc. is one of the worldââ¬â¢s biggest sporting brand based in Oregon USA. Founded in 1968, NIKE is the worldââ¬â¢s biggest designer marketer and seller of athletic footwear, sports equipment, apparel, accessories and services, by sales revenue of $21.5 billion in 2012 (NIKE, 2013). With 48000 employees, NIKEââ¬â¢s operation cuts across different regions in the world including Canada, Asia, Latin America, Europe, and Africa. They posted revenue of $25313 million in the 2013 financial year ending May 2013, the company has enjoy growth in its revenue since 2010, and this trend is expected to continue as they leverage on top sporting events to boost their brand image (Tefris 2013). PESTEL ANALYSIS PESTEL (Political, Economic, Social, Technological Environment, and Legal) analysis is a business analysis technique that is used to analyse the growth potential of a company. It helps firms identify the environment in which they operate, and can firms predict future circumstances and situations by using information and data it provides (Yà ¼ksel, 2012). This report provides a PESTEL analysis of NIKE in the following paragraphs. Political Political environment have a huge implication on the micro and macro environment of a business, and they can significantly influence a range of business decisions (Leslie and Phillip, 2012). Political environment includes political system, government policies and other trade related regulations. Some of the political factors that can affect NIKE includes the relationship between USA (Nikeââ¬â¢s country of origin) and other host countries where NIKE operates (for example China). For example increased tension between US and China can lead to certain aggressive policies that can affect the companyââ¬â¢s operations in China. Furthermore recent pressure on US firms to keep jobs in the US can affect plans for future factory locations of NIKE. Economical The economic environment of the countries NIKE operate in is very vital to the overall strategy and decisions of the company. These factors include the state of the global economy, economic incentives from the countries where NIKE factories are cited, the general economic condition of these countries, inflation rates and changing oil prices. All of these factors can affect the revenue of the company, increased economic growth in emerging markets such as Brazil and China presented a huge revenue opportunity for the company, however recent decline in the growth of the Chinese economy will also have some negative impact of revenue projections of NIKE. Social Social factors can influence the business decisions of NIKE one way or the other. These factors includes tradition, customs, beliefs, level of education, corruption, customerââ¬â¢s consciousness, changing lifestyle, and income distribution (Singla, 2007). For example increased consciousness to maintain healthy living will lead to more demand for fitness centres and gyms that in turn could lead to more sales revenues for NIKE. Furthermore clamour for increased better welfare for workers in clothing factories in countries like China, Indonesia, and Bangladesh, and pressure from the civil society groups like Workerââ¬â¢s Right Consortium on companies like NIKE to ensure their suppliers follow health and safety standards are among some of the social situations and issues the company have to contend with. Technological The commercial success of NIKEââ¬â¢s product is based on technical innovation and quality control in the design and manufacturing process of footwear, athletic equipment, and apparel (Nike, 2014). For this reason changes in technological factors can have serious impact on the overall operations of the company. For example new technology can lead to new products, improve the manufacturing process, and improve the distribution network. This implies that the revenue of NIKE can increased, or there could be reduction in the cost of manufacturing due to better technology. To maintain competitive advantage the company need to constantly understand the technological factors that affect them. Environmental Business operations of firms such as NIKE can have huge impact on the environment. Factors such as climate change, waste management, water management, and use of hazardous chemicals are all environmental impact areas the company has identified. NIKE highlights its commitment to reducing the impact of the companyââ¬â¢s operations through understanding how related these factors are, and how a coordinated approach in the design of its product and processes can mitigate the impact on the environment, and on their business. Legal The judicial system, consumer rights, trade treaties, and ethical codes are all legal factors that affect NIKE. Constant understanding of laws and regulations is imperative to avoid serious legal implication for the company. Gotham (2013) highlights that one serious legal related issue NIKE needs to constantly deal with is the issue of counterfeit product. Ensuring that fake NIKE products are not wide spread is necessary to keep the NIKE reputation, and avoid lawsuits that can increase the legal cost of the company. Furthermore, keeping ethical standards is very vital in protecting the NIKE brand. SWOT ANALYSIS SWOT is a management tool that is used to build strategic business plans (Amin et al, 2011). It is widely used in business due to its simplicity of its four factors (Strength, Weakness, Opportunity and Threats) and its flexibility (Al-Araki, 2013). The SWOT analysis of NIKE is presented in the next few paragraphs below. Strength One main strength of NIKE is its dominant position in the market, and the strong brand portfolio of the company. According to Forbes (2014a) NIKEââ¬â¢s market share in the global footwear market reached 18.6% in 2012, and it is expected to rise to 27% in the long run. The main source of value for NIKE are footwear and apparel that are sold under the NIKE brand, together they make approximately 70% of the overall value of NIKE (Trefis, 2014). This competitive brand portfolio of NIKE and the dominant position of the companyà are key strengths that enables the company outperform the industry. Weakness Watts (2009) asserts that one of NIKEââ¬â¢s weakness is their inability to address problems linked to their labour and factory conditions. The company has been consistently criticised for its lack of control, and dependence on contractors and manufacturers that do not meet labour standard, safe factory conditions in Pakistan, Bangladesh, Indonesia, and China. This has caused to bad publicity for the company, and increased calls for product boycott in recent years. Furthermore the companyââ¬â¢s focus on quality could be a potential weakness as it explore emerging market like Brazil, because its price points will be higher and some customers in these markets could lack the level of income to purchase their products. Opportunities Increased growth in emerging economies presents a huge expansion opportunity for NIKE. The companyââ¬â¢s management believes there is high potential for their products in markets such as China, Brazil, and other emerging countries (Trefis, 2011). The growth these economies enjoy expands the global footwear market, and NIKE is in a strong position to tap into this growth opportunity. Furthermore the increasing use of multi-channel platforms such as online and mobile for shopping is an opportunity for NIKE to reach out to more customers worldwide. Threat The companyââ¬â¢s main threat is its increasing competition, the intense competition and unpredicted changes in in technology and consumer preference in the industry NIKE operates presents a huge risk that can threaten the operations of the company (NIKE, 2013). Some of the main competitors that remain a threat to the company includes Adidas, Puma, and Under Amour. Furthermore, the strong brand value of NIKE products increases the risk of counterfeiting of their products. This is a constant threat the company needs to tackle to ensure it doesnââ¬â¢t lose brand value and revenues. PORTERââ¬â¢S FIVE FORCES ANALYSIS Porterââ¬â¢s five forces analysis helps firms to understand the competition and profitability in an industry, the framework includes potential entrants, industrial competitors, suppliers, buyers and substitutes. According toà Porter (2008) understanding the competitive forces, and their fundamental causes enables companies see the root of current profitability of an industry, while it provides framework that helps anticipate and influence competition over a period of time. The following paragraphs give analysis of the how these five forces influence the competition of NIKE. Potential Entrants Potential new entrants into the market can cause NIKE to lose market share, however in the current situation the risk of potential new entrant to NIKE is minimal because of the high entry barrier because of the established nature of the global sportswear industry. While the risk of new entrants is low, it should be noted that there is a risk of new entrant into NIKEââ¬â¢s existing product line, this can lead to loss of sales and revenue. The company needs to channel its energy into continuously expanding its market share through improving on existing products, and introducing innovative products that will enable them maintain their competitive advantage. Level of competition The level of competition in the global sport footwear and clothing industry is very high. NIKE faces stiff competition from other brands like Adidas and Puma. According to Forbes (2014b) the company faces tough competition in emerging markets and Western Europe, as rival brands like adidas increases their competitive campaign through lunch of products and other related activities aimed at gaining back lost market share. Furthermore, NIKE also faces competition from local brands like Li Ning as they expand to emerging markets like China. The company need to work very hard to continue to protect and expand its brand, for them to be able to maintain the dominant level they are presently. Bargaining Power of Suppliers Suppliers often determine the success of companies selling a product (Bode et al, 2011). However, the availability of commodity items like rubber, and cotton NIKE uses for the production of its goods, and the high amount of suppliers in the industry gives the company absolute advantage over its suppliers. NIKE can choose to switch to any supplier at any time with less cost implication, and low risk of disruption to it supplies due of its brand reputation. Furthermore, every supplier will want to do business with NIKE because of the huge manufacturing ability of the firm. This gives NIKE power over its suppliers, and guarantee of steady supplies. Bargaining Power of customers The loyalty of customers to NIKE brand gives the company bargaining power over its customers. NIKE can decide to set its prices at high levels because it knows customers are willing to pay to be identified with its brand. As long as the company continues offer products that are innovative and appealing to its customers, the company will continue to maintain it strong position, and attract more customer loyalty (Lussier and Kimball, 2014). The bargaining power the company has over its customers gives them a great deal of flexibility in their pricing. Threat of Substitutes There is a high tendency for customers to substitute NIKE products for other brands when they face squeeze in their income during economic downturn. This is due to the fact that NIKE product are considered pricey can could be considered luxury product among certain middle class families if there is a squeeze on their disposable income. Competitors can capitalise on this to release cheaper products that will be appealing to these customer during economic slowdown, therefore NIKE need to constantly monitor the overall economic wellbeing of its customers before introducing any product. ANALYSIS OF NIKE FINANCAL RATIO *Extracted data Ratios Formula 2013 2012 2011 Asset Turnover Ratio Revenue/Total Assets 1.44 1.51 1.39 Return on Assets(ROA) Net Income/Total Assets 14.13% 14.37% 14.22% Return on Equity(ROE) Net Income/Equity 22.28% 21.41% 21.67% Gross Profit Margin (Revenue-COGS)/Revenue 43.59% 43.50% 45.58% Quick Ratio (CA ââ¬â Inv.) / CL 2.60 2.22 2.19 Current Ratio CA/CL 3.47 3.05 2.85 Debt Ratio Total Debt/Total Asset 7.89% 2.49% 4.42% Debt to Equity Total Debt/Total Equity 12.44% 3.71% 6.74% Inventory Turnover COGS/ Inventory 4.16 4.09 4.35 Receivables Turnover Revenue/Receivables 8.12 7.45 6.65 *P/E Ratio 22.90 22.40 18.90 *EPS 2.71 2.37 2.20 Nikeââ¬â¢s revenue increase by approximately 8% in 2013 from 2012 figures, looking at the profitability ratios in the table above, it can be observed that the companyââ¬â¢s profit margin reduced from 45.89% to 43.50% in 2012 and slightly increased later in 2013 to 43.59%. The gross profit margin is a reflection what is left after the cost of production is deducted, other profitability ratios such as ROE also shows upward trend from 2011 to 2013 indicating a favourable year for the company compared to its 2012 figures. This according Forbes (2014a), and NIKE was as a result of pricing actions, and reduce cost of material such as cotton, and lower investment activities by the company in 2013. The asset turnover of the company reduced in 2013 compared to 2012, this could be attributed to the fall in sales in China one of the biggest market for the company. Furthermore, looking at the liquidity ratio of the company, it can be observed that its current and quick ratioà have been i ncreasing within the period under review. For 2013 quick ratio was 2.60times an increase from 2.22times in 2011, this is well above the industry average which is currently at 0.77times. The current ratio of the company has also been increasing in the years under review, this reflects a strong financial position for the firm because it indicates that the company will be able to meet up future debt obligations. Other solvency ratios such as debt ratio and debt to equity ratio saw a high increase from 2.49% and 3.71% in 2012 to 7.89% and 12.44% respectively. This is an indication that the company relies on debt to fund its assets, this can be due to the strong liquidity position of the company which is reflected in its quick and current ratios. The company has the ability to meets its debt obligations so the risk of using debt of using debt is low. Finally from the efficiency ratios it can be observed that the inventory turnover for the company reduced from 4.35times to 4.09times in 2012, and later rose slightly to 4.16times in 2013. This indicates that the company is still slow in the number of times its inventories is sold and replaced compared to the 2011 figure. This could be as a result of the slow recovery of most countries coming out of recession, and slow growth in key markets for NIKE. However this is not a problem peculiar to NIKE, and the company is still above the industry average of 3.6times. The receivable turnover of the company has been increasing within 2011 and 2013, it is possible that this also adds to the increasing liquidity position of the company. The EPS of the company has observed an upward trend from $2.20 in 2011 to $2.71 in 2013, also its P/E ratio also increased 18.90% to 22.90% this is an indication of NIKEââ¬â¢s profitability within these years and it reflects NIKEââ¬â¢s strong position among the investing community. The increasing P/E ratio of NIKE also indicates investorsââ¬â¢ confidence in NIKEââ¬â¢s future earnings and the growth prospect of the company. In conclusion, from the analysis of NIKE financials it is evident that the company maintains a strong position in the industry, because of its inc reasing revenue despite slight drop in certain emerging market, its liquidity position is strong compared to industry average and their growth prospect is also high as reflected in their growth ratios. ANALYSIS OF SHARE PERFORMANCE Figure : Movement of Nike share price in the past 6 months. The figure above presents the share performance of NIKE for the past 6 months, from the figure it could be observed that in the third quarter of NIKEââ¬â¢s financial 2013 year ending May 2014, the share price of the company observed a sharp drop to $70.51, then rose to $79.64 reaching its peak in the period under review. The share price dropped to $73.2 and since then have been fluctuating within 70 and $71. According to NIKE (2013) fluctuations in NIKE share prices can be attributed to various factors that affects performance in these quarter, they include the seasonality of its products, general economic condition, weather condition, and changes in consumer preference. However, dividend pay-out announcements, expectations of quarterly results and other industry related factors could also lead to the fluctuations of NIKE share price. Overall NIKEââ¬â¢s share performance has been fairly stable at $70-$80 as no highly significant drop have been observed in the period under revie w. CONCLUSION In conclusion, the analysis of NIKE indicates that it remains one of the biggest sports manufacturing brands in the world. The companyââ¬â¢s focus on manufacturing innovative products has kept them in a very strong position in the sportswear and clothing industry. Though the global economic growth has slowed down slightly, and this has also affected key emerging markets such as China, growth projections for NIKE remain strong as investors believe the company has the ability to fight off intense competition and continue to expand its dominance in the market. It is very imperative for the company to continue to maintain its level of innovation to ensure continued customer loyalty and increasing revenues.

It besides contain process to plan composite force per unit area vas in the visible radiation of old findings in the existing literature. This chapter besides include the methodological analysis to continue on the undertaking and behavior analysis utilizing Matlab a clip tested package.2.2 Project DescriptionThe usage of metal based CNG cylinders are popularly turning with heightening fatal hazards and menaces manifolds. In Pakistan, the usage of metal based CNG cylinder are turning really fast and therefore adding to multifaceted inadvertent hazards due to low quality criterion cylinders and their mishandling. The grounds behind these effects are use of low quality dyer's rocket and expired kits. A careful estimation shows that out of 10 metal CNG cylinders four are at hazard due to chance of blast and fatal accidents in private and public conveyance vehicles. These in fact are going beginning of serious menaces to human life and cultivate the demand to look into and convey frontward an alternate safe solution. For this intent, metal CNG cylinders may necessitate to be replaced and composite or other stuffs may be the best solution. We will research the chance of composite CNG cylinder under this undertaking. This predominating state of affairs in Pakistan emphasiss on the demand to look into the failing of metal based CNG cylinder and come up with an alternate feasible solution non merely stronger plenty than metal based CNG cylinders but besides cut down the hazard of fatal accidents and life menaces to the consumer. In other words, there is a demand to carry on empirical probe that help us to convey and alternate safe and strong beginning of CNG cylinder fabrication based on composite or other stuffs and compare its viability and strength with the bing metal based CNG cylinder. This survey seek to bridge bing spread in CNG cylinder fabrication and propose some feasible solution to get the better of by taking the restraints with an purpose to hold a feasible alternate solution of high strength, environmental friendly composite CNG cylinder. The undertaking attempt to supply a hazard free competitory merchandise. In this respect, we considered Carbon/Epoxy for the most optimized conseque nces with the high facet of strength and high weight decrease of CNG cylinder. For farther betterment optimisation of wall thickness and fiber orientation is besides be done. We will prove each bed of laminated force per unit area vas with the application of Tsai-Hill failure standards. This application will surely assist us to plan a hazard free composite CNG cylinder. The survey will continue with the specific aim enlisted in to following subdivision.2.3 Aims of the surveyThe chief aim of this survey is to look into the failings of bing metal based CNG cylinder and convey up an alternate feasible solution non merely stronger plenty than metal based CNG cylinders but besides cut down the hazard of fatal accidents and life menaces to the consumer. For this intent, we will analyze the emphasis distribution produced in thin wall metal based CNG cylinder in the visible radiation of different finite component analysis packages and place the weak parts. Hoop and longitudinal emphasiss wi ll be calculated by theoretical analysis of thin wall metal cylinder. Keeping in position the penetration obtained from theoretical and finite component analysis mistake computation will be done. As we have standardized standards, the FEA package with the least mistake will be selected for farther proceeding. We will plan a laminated CNG cylinder on the same specification as of bing metal CNG cylinder. We will further optimise the design by optimisation of angle and thickness of laminated force per unit area vas. The Matlab codification will be generated for laminate analysis of composite CNG cylinder. Subsequently on the Matlab computation will be verified by utilizing ANSYS Workbench 15. The consequences of our design for composite CNG cylinder will be justified from bing literature at domestic ( if any ) and international degree. To gauge and analyse the consequence of fibre orientation on stress distribution of composite CNG cylinder, analysis will be run on different fibre angle orientation. Before continuing on the undertaking in systematic mode we will wish to seek penetration from bing literature in the force per unit area vas context.2.4 General Overview of LiteratureThe history of semisynthetic composite stuff is spread over more than 6000 old ages. The earliest semisynthetic composite stuffs were straw and clay combined to organize bricks for edifice building. Fiber-reinforced composite stuffs besides additions popularity ( despite their by and large high cost ) in high-performance merchandises that needs to be lightweight yet strong plenty to take rough lading conditions ( Shaffer,1993 ) . After the gradual development in the field of complexs over clip it was 2006 when a fiber-reinforced complex was introduced for residential every bit good as commercial usage as a non-corrosive option to steel ( Waterman, 2007 ) . A farther development was observed in 2007 wherein a military vehicle named ââ¬Å" Humvee â⬠, the first all-composite military vehicle, was introduced by TPI Composites Inc and Armor Holdings Inc. It was improved in 2008 by uniting C fibre and Kevlar ( five times stronger than steel ) with enhanced thermoset rosins to do military theodolite instances by ECS Composites making 30-percent igniter instances with high strength ( Pamela J, 2009 ) . This lead to a systematic research on the topic affair which is reviewed in the following subdivision.2.5 General Overview of composite force per unit area vasAs stated in the old bomber subdivision that systematic research work on composite force per unit area vass was initiated late that is i.e. In first decennary of the new millenary ( Sheffer, 1993 ; Waterman, 2007 ; Pamela J, 2009 ; and Rayapuri Ashok and Ranjith Kumar, 2013 ) . Therefore there is utmost vestry of cognition on composite force per unit area vas. To the best of our cognition, there are merely a few surveies are available in this country but research work associating to Pakistan is farther pantie or non bing. Wang Yingjun ( 2010 ) conducted a survey in Japan and a finite component theoretical account of C fibre reinforced polymer ( CFRP ) force per unit area vas with aluminium line drive is established by ANSYS finite component package. The component utilized in the survey was Shell-99 ( 4 node ) . The outer fibril lesion fibres were overwrapped by both hoop twist and coiling twist methods. He found that safety was critical because of high working force per unit area which was more than 35MPa. He conducted the inactive analysis of the vas. The burst force per unit area was predicted farther. He found when interior force per unit area increased up to 65MPa, the maximal tensile emphasis of the first CFRP ply reached rupture strength of CFRP. So the force per unit area 65MPa was regarded as the explosion force per unit area. Rayapuri Ashok and Ranjith Kumar ( 2013 ) in their survey discussed design and analysis of multilayer high force per unit area composite vass along with their advantages over single-channel block vas. Using Abaqus FEA package for burst force per unit area analysis of CFRP composite force per unit area vass for assorted fiber orientation angles, they calculated stress concentration on dish-shaped part. They used element type Solid-46 ( 8 node ) and optimized the fibre angle orientation by analysing the fibre helically for assorted orientations such as [ +25à °/-25à ° ] s, [ +35à °/-35à ° ] s, [ +45à °/-45à ° ] s, [ +55à °/-55à ° ] s, [ +65à °/-65à ° ] s, and [ +75à °/-75à ° ] s. For this intent they utilized burst force per unit area of 35MPa along with rules specified in American Society of Mechanical Engineers ( A.S.M.E ) Sec VIII Division 1. The survey found a per centum economy in stuff of 28.48 % utilizing multilayered composite vass in the topographic point of solid walled vas of SA515 Grade 70 steel. They furthered their probe and used multilayered CFRP stuff and saved 91.62 % stuff when compared to SA515 Grade 70 steel stuff vass. The explosion force per unit areas for assorted fiber orientations are predicted utilizing the Tsai-Wu failure standards. The à ± 25à ° fiber orientation angle is obtained as the optimal fibre orientation angle for the composite force per unit area vas subjected to high internal force per unit area burden. B.Vijay Kiran ( 2012 ) developed an analytical theoretical account for anticipation of optimal fiber orientations for given bed thicknesses. He selected fiber volume fraction= 0.65 and= 0.35 which was acceptable to the present composite force per unit area vas working at 3MPa internal force per unit area. He found optimal value of fiber orientation which was à ±55à ° for glass epoxy and à ±65à ° angle for C fibre. From the finite component analysis study the maximal emphasis obtained in each lamina ( for à ±55, à ±65 degrees weaving angle ) was less than the allowable on the job strength. The factor of Safety 3 was taken for the fibre reinforced composite stuff to get the better of material design and fabrication defects. The mean critical buckling force per unit area was obtained from finite element analysis study was 4.0684N/mm2, which was more than the maximal on the job force per unit area 3N/mm2. Comparison of stiffened and unstiffened complex shell was done by both theoretically and analytically techniques and he found that the stiffened cylinder has more clasping opposition than that of the unstiffened one. Javad Marzbanrad ( 2013 ) investigated the design and analysis of high force per unit area composite vass based on ââ¬Å" unit burden method â⬠along with complete structural analysis and rating of weariness life-time were performed utilizing finite element commercial codification ABAQUS. He selected fiber volume fraction= 0.75 and= 0.25 and element Shell-99 ( 8 node ) . He found that the weariness life-time of vas depends on the finite component mesh size, cleft denseness and ratio in an component. K.M.Pandey ( 2014 ) investigated the clasping behaviour of reasonably thin walled filament-wound carbonââ¬âepoxy cylinders subjected to hydrostatic force per unit area. A entire 9 figure of composite laminates were considered for finite component analysis. He used Finite component package ANSYS 14.0 and three finite component plan ACOS win, MSC/NASTRAN and MSC/MARC to formalize the consequences. He besides used Element 281 ( 8 node ) to make the finite component theoretical account. The ANSYS shell component theoretical account predicted the buckling force per unit area with 1.5 % divergence from the other three finite component consequences. 2.6 Methodology We in our survey and convey for a alternate solution will analyze the emphasis distribution produced in thin wall metal based CNG cylinder in the visible radiation of different finite component analysis packages and place the weak parts. Hoop and longitudinal emphasiss will be calculated by theoretical analysis of thin wall metal cylinder.Theoretical analysis of bing metal CNG cylinder will besides be conducted in the visible radiation of insight addition from work by P.Beer and Johnson ( 2006 ) . The demand for theoretical analysis emerged as to supply a base for design of composite CNG cylinder. Keeping in position the penetration obtained from theoretical and finite component analysis mistake computation will be done. As we have standard standards the FEA package with the least mistake will be selected for farther proceeding.We will plan a laminated CNG cylinder on the same specification as of bing metal CNG cylinder. We will further optimise the design by optimisation of angle and thickness of laminated force per unit area vas. The Matlab codification will be generated for laminate analysis of composite CNG cylinder. The Matlab computation will be verified by utilizing ANSYS Workbench 15. The consequences of our design for composite CNG cylinder will be justified from bing literature at domestic and international degree. To gauge and analyse the consequence of fibre orientation on stress distribution of composite CNG cylinder, analysis will be run on different fibre angle orientation.2.7 Matlab codification for design of composite force per unit area vasclear all clc % Design of composite force per unit area vas % Properties of C fibre/epoxy with 60 % volume fraction % SI unit system fprintf ( ââ¬ËDesign Of Composite Pressure Vessel ââ¬Ë ) fprintf ( ââ¬ËProperties of Carbon Fibre/Epoxy with 60 per centum Volume fraction ââ¬Ë ) fprintf ( ââ¬ËModulus of Elasticity in Longitudinal Direction ââ¬Ë ) E1=134*10^9 % Pa fprintf ( ââ¬ËModulus of snap in cross way ââ¬Ë ) E2=7*10^9 % Pa fprintf ( ââ¬ËShear Modulus ââ¬Ë ) G12=4.2*10^9 % Pa fprintf ( ââ¬Ë Posion Ratio ââ¬Ë ) v12=0.25 fprintf ( ââ¬Ë Longitudinal tensile break strength ââ¬Ë ) XT=1270e6 % Pa fprintf ( ââ¬Ë Transverse tensile break strength ââ¬Ë ) YT=42e6 % Pa fprintf ( ââ¬Ë Shear Strength ââ¬Ë ) Sh=90e6 % Poision Ratio fprintf ( ââ¬ËLongitudinal compressive break strength ââ¬Ë ) XC=1130e6 % Pa fprintf ( ââ¬ËTransverse compressive break strength ââ¬Ë ) YC=141e6 % Pa fprintf ( ââ¬ËInner radius of force per unit area vas ââ¬Ë ) r=.1335 % m % Inner radius of force per unit area vas fprintf ( ââ¬ËBurust force per unit area applied ââ¬Ë ) p=75e6 % MPa % Pressure applied fprintf ( ââ¬ËThickness of force per unit area vas ââ¬Ë ) t1=0.01182 ;

Most of the literature available on composite force per unit area vas is about optimisation of fiber orientation while major part of it is about Glass fiber wherein the research workers identified the emphasis distribution utilizing different fiber orientation. These surveies found the consequence curtailing weight decrease by about 29 % ( K.M.Pandey, 2014 ; Javad Marzbanrad, 2013 ; and Rayapuri Ashok, 2013 ) . For analysis purpose many of research workers benefited from ANSYS as the finite component analysis package because this to them provides more user friendly interface and extremely elaborate analysis compatibility. They selected Shell-99 and Solid-46 ( 8 node ) as component for more optimized consequences. Their most important findings were that Carbon/Epoxy had provided the highest strength consequences with a comparatively high weight decrease. They conducted their probe at 54.7à ° because they presume that it could supply the most optimized consequences but it may non be allowable practically as referred by B.Vijay Kiran ( 2012 ) . They have besides selected 4 and 8 node elements wherein 16 node component is preferred because of its more precise consequences. The other surveies under reappraisal besides used maximal shear emphasis theory while on the other manus Tsai-Hill failure theory provide more better consequences in multilayered laminate analysis. These surveies besides used Abaqus package which may give less attested consequences when compared to analysis through ANSYS Workbench. We in our survey attempt to get the better of this spread and convey a feasible alternate solution of high strength, environmental friendly composite CNG cylinder.We have utilized Matlab for numerical analysis of laminated force per unit area vas. The merchandise will travel through a battery of trial in order to conform its genuineness and cogency.

Archimedes theory of a circle ABCD and a triangle K
Archimedes theory of a circle ABCD and a triangle K Archimedes compared the area enclosed by a circle to a right triangle whose base has the length of the circleââ¬â¢s circumference and whose height equals the circleââ¬â¢s radius. If the area of the circle is not equal to that of the triangle, then it must be either greater or less. He then eliminates each of these by contradiction, leaving equality as the only possibility. Archimedesââ¬â¢ proof consists of constructing a circle ABCD and a triangle K. Archimedes starts by inscribing a square in the circle and bisects the segments of arc AB, BC, CD, DE subtended by the sides of the square. Afterwards he proceeds to inscribe another polygon on the bisected points. He repeats this process until the difference in area between the circle and the inscribed polygon is smaller than the difference between the area of the circle and the area of the triangle. The polygon is then greater than the triangle K. Archimedes then proceeds to explain that a line from the center of the polygon to the bisection of one of its sides is shorter than the radius of the circle, and its circumference is smaller than the circumference of the circle. This disproves the statement that the polygon is greater than the triangle, since the legs of the triangle are made up of the radius and circumference of the circle. The triangle K cannot be both smaller and larger than the polygon, and thus cannot be smaller than the circle. After Archimedes proved that that the triangle cannot be smaller than the circle, he continues to prove that the triangle cannot be larger than the circle, either. This is accomplished by first assuming the triangle K to be larger than the circle ABCD. Then, a square is circumscribed around the circle so that lines drawn from the center of the circle will go through the points A, B, C, and D and bisect the corners of the square, one of which Archimedes labels T. Archimedes then connects the sides of the square with a tangent line and labels the points at which the line meets the square G and F. He goes on to say that because TG GA GH, the triangle formed by FTG is larger than half the area of the difference in area between the square and the circle. Archimedes uses the fact that continual bisecting of the arc of a circle will produce a polygon with this characteristic to assert that continuing this method will ultimately produce a polygon around the circle such that the difference in area between the polygon and the circle is less than the difference in area between the triangle K and the circle. The polygon is thus less in area than the triangle K The length of a line from the center of the circle to a side of the polygon is equal to the radius of the circle. However, the perimeter of the polygon is larger in length than the circumference of the circle, and since the circumference of the circle is equal to the length of the longer leg of the triangle, the polygon must be larger in area than the triangle K. Again, the triangle cannot be both larger and smaller than the polygon, so the triangle cannot be larger than the circle. Archimedes accomplished to prove his theory by using contradiction. After he proved that the triangle with legs equal to the radius and circumference of a given circle is not greater or less in area than that circle he concludes that the two must be equal in area.

Cross Cultural Management Essay Example | Topics and Well Written Essays - 2000 words - 3
Cross Cultural Management - Essay Example The first is to present some cultural profiling between two countries, using a range of academic models which should highlight any significant differences that are likely to occur in terms of management behaviour. Secondly, aim to critically evaluate the key communication and negotiation differences that managers should be aware of when dealing with the negotiators when they arrive. Negotiation is generally considered as a means of resolving conflict. It is a process in which problems are solved between two or more parties that attempt to settle some disagreement in a manner that is agreeable to both (Fisher, Ury & Patton 1991, pp. 1-3). Although the main principles of negotiation are easily understood, it can be extremely difficult when placed into practice. Contention between what is right or wrong; opposing views when it comes to what is fair and just; forms of communication and information exchange as well as the procedures carried out for negotiations are only a handful of the challenges that negotiators often encounter (Susskind, McKearnan & Thomas-Larner 1999, pp. 2-57). Furthermore, the process of negotiation is made difficult when different parties are negotiating across conflicting cultures (Gelfand & Brett 2004, pp. 45-47). Culture is one of the most powerful factors that determine and influence peopleââ¬â¢s way of thinking as well as behaviour an d communication (Salacuse 1993, pp. 199-208). Therefore, culture has a significant effect on the peopleââ¬â¢s means of negotiation. This essay specifically examines the impact of culture on the process of negotiation. First, it provides cultural profiling between India and Japan, and identifies differences between their culture and management behaviour. Important factors that are involved in cross cultural negotiation such as communication and negotiation differences are also tackled. In addition, the four dimensions of culture identified by Hofstede (1997, pp. 28-37) have been included,
