Between the cultures Essay Example | Topics and Well Written Essays - 1000 words
Between the cultures - Essay Example The city was strangely quiet. Nobody was in the streets and it seemed like everyone was dead. Since it was my first night in the city, I was wondering what kind of city it was. I forced my way back towards home with no bread, and ready to starve till the next morning. I was eighteen years old, and I had been accepted in Yazd University, in the city of Yazd in my country, Iran. I rented an apartment with three other friends of mine and we moved in only that day. It was the first time we had left our homes. All of us were inexperienced in the home affairs, and now we were in a new and strange city with weird people for studying. I had grown up in Tehran, which is the capital of Iran. It had a population of more than ten million people. Whenever you wanted, you could find a grocery store, a restaurant or anything else you wished. Many people immigrated from country sides to Tehran for business, studying and residence in the most developed city of Iran. Tehran was a multicultural city. E very Iranian enjoyed living in such a big city like Tehran. But at the age of eighteen, I moved four hundred miles far from Tehran, to the city of Yazd. It was a small city with religious and intolerant people. Most of the men in Yazd wore beard and women used black burka. People of Yazd had a traditional life which was very hard for me to adapt. The new environment, situations and differences between my hometown and Yazd caused the feeling that I was living between two different cultures. I always liked my hometownââ¬â¢s culture, but I was not interested in the culture of Yazdââ¬â¢s people. It was really annoying for me and the students from the other cities to be a part of the same. I was in a constant struggle between the two cultures, however it was hard to ignore and get rid of it. The next day after starving, I and my friends went to the university to start our new semester. The university was similarly a weird place like the city of Yazd and its inhabitants. The securit y freaks the fashion of every boy and girl at the entrance gate of the campus. They had banned jeans pants for the boys, and it was obligatory for girls to use black burka. Every physical and verbal contact between a boy and a girl was reported immediately to the student life office. Also in the classrooms, front seats belonged to boys and rear seats belonged to girls. The university had lots of rules for segregating boys and girls. They knew their rules according to the Islamic creed. They tried to unify studentsââ¬â¢ culture, which I felt disgusted about. Sometimes I thought Taliban moved in from Afghanistan to our university in Yazd. I and my friends had never seen such a university like that. We had never expected anything of this sort. On the way back home, we bought lots of food to keep in our cooler because we didnââ¬â¢t like to suffer due to hunger after eight oââ¬â¢clock when everything got closed. When we got home, we were still surprised and wondered about our fi rst day at the university. We started to talk and laugh about ridiculous rules of our university. After a while one of our friends, who had a late evening class arrived at the main the door of the apartment. Since the door bell was broken and he didnââ¬â¢t have the key, he called through his cell phone to us, and asked us to drop the key for him from the balcony. One of my friends went into the balcony and dropped the key for him and he came upstairs. As he walked into the apartment, we heard a very loud sound. Someone was knocking the main door of

Crisis management japan earthquake Assignment Example | Topics and Well Written Essays - 500 words
Crisis management japan earthquake - Assignment Example The effect of this earthquake was felt in Tokyo that is 300 miles away from the place of the crisis. There were no damages reported after this crisis. The major reason for this is because it was far off the coast. In this section, we are going to focus on the social media. In this era of technology, the social media can be used to manage a crisis or even to make the crisis worse than it already is. Whenever one is dealing with a crisis, there is need to come up with a disaster management team that will look into the possible ways to quell the effects of the crisis. In the 2013 Japan Earthquake among the modes used to reach out to the people was through the social media. Firstly, in the 2013 Japan earthquake, the social media was used to inform the world about the crisis. The social media was used as one of the communication channels used to deal with the crisis. There are people who could not watch the news but with their mobile gadgets, they followed up the whole incidence from wherever they were. The social media was also used to warn people against staying in the areas that had been affected by the crisis. This information was important as a precautionary measure incase another disaster was triggered by the earthquake. The survivors of the disaster also used the social media to tell their experiences during the crisis. The social media was also used to pass messages of encouragement to the victims of the crisis. Through the social media, those people who had to relocate to higher grounds got the assistance from the donations that the social media users raised. As stated above, the social media can be for the good of a crisis as well as an avenue for more disaster. Through face book sharing and re-tweeting options, people who would have been helped were not helped. It came to the attention of the authorities that it was not possible to locate the source of the information. In future it is important that

Building and construction Safety Technology Assignment
Building and construction Safety Technology - Assignment Example The paper tells that the construction workers are the people who will be using the hoist frequently, and therefore more likely to be injured by the hoist. To avoid accidents that might be caused by their negligence, it is important for them to be trained on how to use the hoist and some safety precautions. A material hoist should be manually controlled by a well trained operator so as to ensure safety of other workers lacking the technical knowhow of a material hoist operation. All the workers should be provided with a simple list of doââ¬â¢s and donââ¬â¢ts safety information to reduce the risk of self injury due to carelessness. The material hoist must be designed in such a way that it is enclosed in a compartment which has openings on each floor which will act as doors. Each opening should have a landing plate which will clutch the hoist when loading and offloading. The material hoist motor should have a speed governor and an equipment to measure the weight of the load being lifted. The maximum weight to be lifted by the hoist should be effectively communicated to the workers responsible for loading the hoist to avoid overloading. The lubrication of the bearings and gears should be as often as possible to avoid friction and wearing out of joints and wheels. This will also ensure that the hoist motor is not overloaded and reduce the risk of malfunction. The material hoist should be suspended from steel wire ropes of highest possible quality which corresponds with the weight to be lifted. ... This will also ensure that the hoist motor is not overloaded and reduce the risk of malfunction. The material hoist should be suspended from steel wire ropes of highest possible quality which corresponds with the weight to be lifted. The steel wires should have an allowance for environmental factors such as cold and hot weathers which cause expansion and contraction of the ropes. If overstretched, the ropes may break during cold seasons. A number of steel ropes should be used so that when one breaks others hold the hoist before repair is done (Craighead 210). The minimum diameter of the steel ropes should not be less than 8 millimeters. Other requirements Sound reduction is one of the emerging trends in the field of escalators. The sound of a material hoist should be as low as possible therefore increasing the ability to identify a problem with the hoist when it arises. Sound reducing rubber pads should be installed to eliminate noise and vibrations that might otherwise cause weakeni ng of the beam and the hoistââ¬â¢s frame work. It is recommendable to use stainless steel for the material hoist housing since it has a relatively small weight and yet high capacity of not getting torn apart when lifting heavy loads. Unless stated otherwise, stainless steel should be of EN 10029, EN 10048, EN 10095, EN 10259 or EN 10258 grades 316 or corresponding. Question2. Crane Safety Precautions A crane should be properly maintained and repaired when damaged to avoid its malfunctioning while lifting loads. Before a crane can be employed to lift iron bars, its capacity should be considered. A crane which has a low capacity to lift the weight of the iron bars should not be used; otherwise it may cause injury to those operating it. The hoist rating of the crane should be

An Exploration into the factors Influencing Consumer Purchasing Thesis Proposal
An Exploration into the factors Influencing Consumer Purchasing Decision - A case study of Thai Fashion - Thesis Proposal Example The culture of showing preferences in luxury was not only a culture of the rich but also the middle class and the low-class members of the society. The younger generation of the female population had grown to be fashion conscious as the influence of the media and commercialization took a toll on the fashion industry. Given that, Thailand fashions were selected and purchased at face value, many luxury fashion brands established a promotion method, which included hiring celebrities and other public figures to promote their brands. (Rocha & Hawkins, 2005). Research has shown that the moods and emotions that were evoked by different fashion garments influenced the consumer purchasing decision either positively or negatively. Consumers chose brands based on reliance, personal style, brand image and celebrity influence (Bruce & Daily, 2006). They discovered that the notion of a consumer to acquire a modern look was based on emotions that drove the consumers to buy luxurious fashion brands. This kind of fashion relied on pleasure rather than one's needs and wants. Thai consumers have adopted the behavior of making purchases based on finding new stimuli, sensations, and pleasure. These aspects are personal and very subjective tilting the purchase decision to be oriented to the particular individual (Balckwell&Talarzk, 1983). The consumer personality also had a major influence on the purchase decision. One's personality factor in things like the individualââ¬â¢s self-esteem and body shape.

The Tipping Point Essay Example for Free
The Tipping Point Essay Change is a rule by nature that will never change. Shifting from one state to another state is natureââ¬â¢s law. No one can override this rule. Tipping point by Malcolm Gladwell is all about changes that happen frequently. No one is stable in this world; nothing is stable in this world. Every thing must change consistently, the things, which happened yesterday, is not same today and the things which happened today will not be same tomorrow. This law is not only applicable for human life but also for society, technology, disease, education, culture, music, craft and so on. A wide spread outbreak of an infectious disease is called as epidemic. Malcolm Gladwell also deals with this epidemic not with medicine but with social epidemic that spoils young generation and society. Smoking is injurious to health, Drinking is injurious to wealth. Every one knows this, but they drink and smoke until malady bangs them. A womenââ¬â¢s tongue is more powerful than any other thing? What is the reason behind crime rate fell down so drastically? What is the reason behind young generation using mobile à phones, ipods, and desktop and laptop computers than elder generation? Why some use Internet for utile purpose and not others? Why violence step-up in Hollywood movies? There are many questions here but Malcolm Gladwell answers only one question that is the correct answer for remaining questions. Ideas, behavior, messages and products sometimes behave just like outbreaks of infectious disease. They are called as social epidemics. The Tipping point is a book that deals with social epidemics that surround us. Generation after generation every thing right from culture, music, dress, changes frequently in a very unusual way. For example, if a famous pop star changes his dressing style, everyone will have a tendency to dress like him. It is called trend. This trend changes often, and no one knows this transition. The working of social epidemic is distinctly separate and societyââ¬â¢s mind were stormed by à This unusual occurrence. For example we can look at twin tower disaster in New York City. A film taken by novice artists and technicians may yield stunning victory. No one knows the working of epidemic. The title ââ¬Å" The Tipping Point ââ¬Å" is originated from the world of epidemiology. The Tipping Point is a proper mixture of sociology, psychology, and history. This is a book for one who wishes to understand the world around them is in different way. The Three Influential People Connectors, Mavens and Salesmen. à Connectors can be compared with computer hub. They play a major role in epidemic like the central part of a car wheel. Hub is used for networking one computer with other. They are the heart of computer networking. Connectors have the habit of voluntarily introducing themselves to strangers and others. They can easily mingle with any sort of people. Hub in computer can be connected to any other computer irrespective of their configuration and software installed, like wise connectors can amalgamate with any sort of people in the society without any hesitation. Connectors are very rare in the society. Mavens are very intelligent people, they know how to interact with society, they how to exploit decrepit of the society. Mavens are intelligent powerful social epidemic. ââ¬Å"Mavenâ⬠the word comes from Yiddish meyvn and Herbrew mevin (ÞÃâà ¿Ãâ¢ÃŸ, with the same meaning, which in turn derives from Herbrew binah, means understanding. It was recorded in english language in 1952, and become famous in the 1960s by a series of commercials for Vita Herring created by Martin Solow, featuring ââ¬Å"The Beloved Herring Mavenâ⬠. Since the 1980s it has become more common since William Safire adepted it to describe himself ââ¬Å" the language mavenâ⬠. The word is mainly confined to American English, but had not yet appeared with the publication of the 1976 edition of Websterââ¬â¢s third new international dictionary. In network theory and socilogy, a maven is someone who has a disproportionate influence on other members of the network. The role of mavens in propagating knowledge and preferences has been established in various domains, from politics to social trends. Gladwell also suggests that mavens act most effectively when they have some kind of understanding with connectors. Connectors can easily and widely distribute the advice or insight of a mavens. Some have identified the maven is not a Jewish word, but a Jewish concept. A maven is an expert, and itââ¬â¢s something that every Jew thinks he is on every subject that exists. The term Maven is used to a great extent in spam electornic mails. Spam is nothing but an email from unrecognized location or person. The objective behind spam electronic mail is to develop and promote their business and to to earn handsome of money. Some Spam email contains VIRUS ââ¬â Virtual Information Resource Under Sledge. An agreement or contract in which property is transferred from the seller to the buyer for fixed price in money (paid or agreed to be paid by the buyer) is called as sales. It is an integral part of social activity. Ideas or products found attractive or interesting by others will grow exponentially for some time is called as stickiness. People always look for different kind of music systems like Walkman, Discman or even those expensive mp3 players And finally they stick with ipods. Apple is the second biggest company next to Microsoft Apple introduced ipods in which hundreds and thousands of songs can be saved and played whenever required. This allowed the company to not only exploit they name but also use the names of Dell and Microsoft to work with them for their success. Also this product tipped of the timing. At a time when the health conscious and the craze is at its peak, people were looking for something to play their music while they were working out that looked cool. This is exactly what the IPOD offered these people. It is compact, mini, nano, shuffles are so small they can easily fit in your pocket with no worries about skipping, even while running. The overall benefits of this product are enormous, and the sleek plain design really set it apart from anything in the market. If a kid in a college doesnââ¬â¢t have one of ipod, laptop, cell phones, people are surprised. The point that I try to get from Gladwell is the importance of Maven in having something tipped. Whether is accidental or on purpose the maven finds out information about something and has to tell someone. I feel it has tipped and think it was a fabulous example of marketing tipping a product. I think Gladwell really hit the nail on the head with his main three points that contribute to the tipping point of anything. At a time when the health conscious and the craze is at its peak, people were looking for something to play their music while they were working out that looked cool. This is an incredible underground of ipod mavens. One who links like-minded people and one who gathers and shares deep information, that sounds the definition of almost every relationship is the blogger, they are connectors and mavens at the tipping point of communication. Cell phone, ipods, desktop and laptops are the tipping point of communication because no other form of communication has been so immediate, so interactive, so far-reaching and so ready-made for relationships. We are connectors and mavens at the tipping point of communication able to make relationships with people all over the planet. We are just beginning to figure out the depth and breadth of the medium in which we are working. With the relationships we are making and the information we are gathering. If we set our minds in the same direction, we can change the world. The whole thing changes when the world is our community. Adoption of Ipods Advent of Cell Phones, Laptop and Desktop. Bolstered by the recent holiday gift-giving season, the number of American adults who now own an iPod or other MP3 player has reached 22 million, according to a Pew Internet American Life survey. à Based on the findings of this survey, it is clear that this technology reached its tipping point in the 2004 holiday shopping season, said Lee Rainie, director of Pew Internet American Life. iPods and other MP3 players have broken into the mainstream in a new way, and were projecting a lot more growth, probably an acceleration of growth, ahead. The survey was conducted between January 13 and February 9, 2005 to gauge roughly how many American adults now own iPods or MP3 players. The study didnt poll teenagers, an age group that includes several million more users of such devices. Pew determined iPods and other MP3 players are likely being adopted so quickly because of their relative ease of use, a plethora of downloadable music on the Internet, and because they allow people to become their own disk jockeys. People are beginning to adapt them as instruments of social activity, sharing songs with others, and are becoming drawn into podcasting, Rainie said. Although the study didnt offer specific numbers for podcastings growth, Rainie predicts in 2005, podcasting is likely to surge in popularity along a growth curve comparable to the blogging communitys rapid expansion. Pew is currently conducting a study looking at the growth of podcasting, results of which will be released in mid-March. Key findings of the survey include: â⬠¢ Men are more likely to own iPods/MP3 players than women. Roughly 14 percent of adult men have such devices, as opposed to nine percent of adult women. â⬠¢ Almost one in five (19 percent) of adults under the age of 30 have iPods/MP3 Players, versus 14 percent of people in their 30s and 40s. â⬠¢ iPods/MP3 players are generally gadgets for the well-to-do. Approximately 24 percent of adults with household incomes of $75,000 or more own a device. About 10 percent of adults living in households earning $30,000 to $75,000 have them, as opposed to 6 percent of those living in households with earnings under $30,000. â⬠¢ Internet users are four times as likely as non-Internet users to have iPods/MP3 players, probably because Web users are able to get much of the music they enjoy online; 15 percent of Internet users have iPods/MP3 players, versus only four percent of non-Internet users. â⬠¢ The more advanced the Internet user, the more likely it is s/he will own an iPod/MP3 player. Those with six or more years online experience are twice as likely to have them as those who first came online in the last three years. â⬠¢ Broadband access is strongly linked to iPod/MP3 player ownership. About 23 percent of adults with high bandwidth have the devices, compared to nine percent who connect via dial-up. Among adults with broadband access both at home and at work, 31 percent own such devices. â⬠¢ Approximately 16 percent of parents living with children under age 18 have an iPod/MP3 player, as opposed to nine percent of those with no children living at home.

The Telangana Rebellion Essay Example for Free
The Telangana Rebellion Essay The Telangana Rebellion was aà peasant revoltà which was later supported by theà Communists. It took place in the formerà princely stateà of Hyderabad between 1946 and 1951. This was led by theà Communist Party of India. [5] The revolt began in theà Nalgonda districtà and quickly spread to theà Warangalà andà Bidarà districts. Peasant farmers and labourers revolted against the localà feudalà landlords (jagirdarsà andà deshmukhs) and later against theà Osman Ali Khan, Asif Jah VII. The initial aims were to do away with illegal and excessive exploitation meted out by these feudal lords in the name ofà bonded labourà (Vetti Chakiri). The most strident demand was for all debts of the peasants to be written off. [6][7] Among the well-known individuals at the forefront of the movement were leaders likeà Anabheri Prabhakar Rao, Bathini Mogilaiah Goud,à Doddi Komraiah,à Bandi Yadagiri,à Suddala Hanumanthu,à Acharya Konda Lakshman Bapuji,à Chakalli Iylamma,Komaram Bheem,à Puchalapalli Sundaraiah,à Makineni Basavapunaiah,à Chandra Rajeswara Rao,à Raavi Narayana Reddy, Bommagani Dharma Biksham,Arjula Ramana Reddy, theà Urduà poetà Makhdoom Mohiuddin,à Hassan Nasir,à Bhimreddy Narasimha Reddy,à Mallu Venkata Narasimha Reddy,à Mallu Swarajyam,à Arutla Ramchandra Reddyà and his wifeà Arutla Kamala Bai. The violent phase of the movement ended after the central government sent in the army. Starting in 1951, the CPI shifted to a more moderate strategy of seeking to bring communism to India within the constraints of Indian democracy. [10] In 1937,à Time magazineà saidà Hyderabad stateà was the richest native state in India. Budget allocations to Telangana are generally less than 1/3 of the total Andhra Pradesh budget. There are allegations that in most years, funds allocated to Telangana were never spent. Telangana JAC leaders say that only 20% of the total Government employees, less than 10% of employees in the secretariat, and less than 5% of department heads in the Andhra Pradesh government are from Telangana.None of these allegations were proved wrong by theà Sri Krishna Committeeà due to lack of data, and its choice to compare regions. Proponents of a separate Telangana state feel that the agreements, plans, and assurances from the legislature and Lok Sabha over the last fifty years have not been honoured, and as a consequence Telangana has remained neglected, exploited, and backward. They feel that separation is the best solution. Srikrishna Committee report The Srikrishna committee on Telangana submitted its report in two volumes to the Home Ministry of India on 30 December 2010. In an all-party meeting on 6 January 2011, the Home ministry made the 505-page Srikrishna committee report public. Section 9-3 (page 440) of the report[69]discusses six solutions. The Committee announced that they were recommending keeping the State united, and advised constitutional and statutory measures for socio-economic development and political empowerment of Telangana region through the creation of a statutorily-empowered Telangana Regional Council. Telangana leaders say the best option from the Sri Krishna committee report is the formation of separate Telangana state with Hyderabad as its capital. They plan to pressure the Central government to zero in on this option as the only workable one. The MP also lashed out at Telangana Rashtra Samithi (TRS) President K Chandrasekhar Rao, and alleged that KCR was misusing the Telangana sentiment to get all prominent posts for his family members and people belonging to the upper caste. In the name of Telangana, KCR and his family members joined the Congress party and occupied all posts without giving a chance to weaker sections, Theà 2G spectrum scamà involved officials in the government of India illegally underchargingà mobile telephonyà companies forà frequency allocationà licenses, which they would use to createà 2Gà subscriptions forà cell phones. According to a report submitted by theà Comptroller and Auditor Generalbased on money collected fromà 2Gà licenses, the loss to the exchequer wasà 176,379à croreà (US$38. 27 billion). The issuing of the 2G licenses occurred in 2008, but the scam came to public notice when theà Indian Income Tax Departmentà investigated political lobbyistà Niira Radiaà and theà Supreme Court of Indiaà tookà Subramaniam Swamys complaints on record ? 2G licenses issued to private telecom players at throwaway prices in 2008 ? CAG: Spectrum scam has cost the governmentà Rs. 1. 76 lakh crore ? CAG: Rules and procedures flouted while issuing licenses CHEAP TELECOM LICENSES * à Entry fee for spectrum licenses in 2008 pegged at 2001 prices * à Mobile subscriber base had shot up to 350 million in 2008 from 4 million in 2001 NO PROCEDURES FOLLOWED * Rules changed after the game had begun * Cut-off date for applications advanced by a week * Licenses issued on a first-come-first-served basis * No proper auction process followed, no bids invited Raja ignored advice of TRAI, Law Ministry, Finance Ministry * TRAI had recommended auctioning of spectrum at market rates Politicians involved * A. Raja, the Ex-Minister of Communications and Information Technologyà who was the minister when the controversial second round of spectrum allocations took place. Mr. Raja, an MP of theà Dravida Munnetra Kazhagamà from theà Nilgirisà constituency, was forced to resign following the public outcry. * Arun Shourie, th e minister for Telecom during 2003 in the previous BJP regime. It was Arun Shourie who introduced the controversial technology neutral Unified Access(both Basic amp; Celluler) Services License, which allowed fixed line operators who had paid much lower license fees to offer mobile phone services, at first in the limited WLL mode (Wireless local loop) and later, following an out of court settlement between mobile operators and the BJP govt, full mobility. This gave an advantage to players like Reliance and Tata Teleservices who managed to get mobile spectrum without paying the hefty fees that earlier operators likeà BPL Mobileà had paid. Pramod Mahajan, the minister for Telecom between 1999 and 2003. Mr. Mahajan was the minister when the BJP Government took the controversial decision to shift from a license fee based regime to a revenue sharing model which was roundly condemned both by political parties and by economic experts. [4]à Theà Comptroller and Auditor Generalà also filed adverse reports citing a loss of overà 64,000à croreà (US$13. 89 billion)à caused by this decision. The crux ofà A. Rajas defence is that he was following a policy of 2G allocations put in place by the BJP and it ould be unfair to levy prices based on 3G spectrum to 2G licenses. Pramod Mahajan, who was seen to be friendly with various corporate houses, had been brought in to replaceà Jagmohanà as Telecom minister just days before the decision was announced. The houses and offices of the bureaucrat were recently raided by theà Central Bureau of Investigationà as part of their investigations. R K Chandolia, private secretary of Raja during UPA-I when the licences were awarded. He was anà Indian Economic Serviceà officer of the 1984 batch cadre. When Raja became the Telecom Minister once again in UPA-II, Chandolia had been promoted to the Joint Secretary rank. Raja re-designated him Economic Adviser, that gave him the charge of all important policy-related work. Chandolia interacted with all the licensees. It is said that it was Chandolia who, from DDG-access services A K Srivastavas room, had handed out letters of intent to representatives of various companies. [8] The Central Bureau of Investigation on Tuesday night arrested Dynamix Balwas group managing director Shahid Usman Balwa in connection with the 2G spectrum allocation scam. Season 3 was under the leadership of Lalit Modi , however Season 4 is going to be under the leadership of Chirayu Amin. He has already promised a bigger and better IPL and has promised to run it in a transparent manner. This year there was a lot of allegation of match fixing . BCCI and its pet Indian Premier League came under Income Tax raids. IPL Season 4 is going to have 10 teams , 74 matches and 45 days of action. No player can play more than 14 matches . This rule is laid to prevent player burnout. Sony / World Sport Group has won the rights for 10 years at Rs 8,700 crore (US$ 1. 94 billion) For IPL 4 , BCCI has asked MSM to pay Rs. 190 crores extra. This extra amount is to compensate for the increase in number of matches. The extra money will be paid for the 14 matches in a pro rate basis. Mahela Jayawardeneà has been appointed captain of the new IPLà franchiseà ââ¬â Kochi. The 33-year-old former Sri Lankan captain was purchased by the Team Kochi for a whopping $1. 5 million at the player auction last month. Until last year for the previous 3 seasons of IndianPremierà League, he was part of the Kings XI Punjabà franchise. Theà 2010 Commonwealth Games, officially known as theà XIXà Commonwealth Games, were held inà Delhi,à India, from 3 to 14 October 2010. A total of 6,081 athletes from 71à Commonwealth nations and dependenciesà competed in 21 sports and 272 events. It was the largest internationalà multi-sport eventà to be staged in Delhi and India, eclipsing theà Asian Gamesà inà 1951à andà 1982. Theà openingà and closing ceremonies were held at theà Jawaharlal Nehru Stadium, the main stadium of the event.

The official mascot of the Games wasà Sheraà and the official song of the Games, Jiyo Utho Bado Jeeto, was composed by celebrated Indianà musicianà A.R. Rahman. Initially,à several concerns and controversiesà surfaced before the start of the Games. Despite these concerns, all member nations of theà Commonwealth of Nationsà participated in the event, exceptà Fiji, which is suspended from the Commonwealth, andTokelau, which didnt send a team. A widely-praisedà opening ceremonyà helped improve the image of the Games. [2][3]à The concerns raised during the buildup to the Games proved largely unfounded as most events progressed smoothly. The finalà medal tallyà was led byà Australia. The host nation India gave itsà strongest performance yetà to emerge second, whileà Englandà placed third. The day after the conclusion of the Games, the Indian Government announced the formation of a special investigation committee to probe the allegations of corruption and mismanagement that had marred the buildup to the Games.

The Manual Transmission System
The Manual Transmission System In this report, I am going to compare and contrast the difference between Toyota 5 speed manual gearbox transmission and Toyota 5 speed automatic transmission system. 2. History of the transmission In 1894 Louis-Rene Panhard and Emile Levassor invented the modern transmission. Today we still use the same concept since it was introduced. The concept is still the same that the crankshaft connects from the engine to the transmission shaft through clutch. The latter is mounted to gears which control and operate the transmission of the motion that is coming from the engine to the wheels. Few experiments have been done about type and numbers of gears but still until today the same concept is applied. To make it easier for the driver to control speed and with help of gears, synchromesh gears and a live rear axle were invented. Instead of having gears engage and disengage again from each other, a car transmission that had gears and continuous with each other was introduced, all the gears were moving and the dog clutch was designed in order to connect the gears that are caused to rotate by engine and move the wheels forward. Different gears with different sizes are designed to increase or decrease the momentum of the vehicle. The most popular transmissions were 4 speed transmissions which its top gear (4th) had a ratio of 1:1 while other gears had lower ratios. Then, engineers came with a 5th gear in which will increase the ratio by 1 between the engine rpm and the wheel rpm that is known as overdrive. American inventors Harold Sinclair and Richard Spikes designed automatic transmission while German inventors invented the automatic transmission rudimentary design. While General Motors provided automatic transmission in all of their cars that were manufactured from 1938 and by the end of 1940s most of the car manufactures offered at least one transmission in their models. Electric cars also fitted with electric car transmission. Now the market for automatic transmission is huge and most cars are manufactured with it (Car transmission, 2006) 3. Automatic transmission system This is the type of transmission that is capable of changing the gear ratios automatically while the vehicle is moving without the need of the driver to manually change the gear using the gear stick. The main purpose of the transmission is to provide the following outcome: Neutral to keep the engine running without the gear, or moving the vehicle. Lower gears for taking off purpose and for operating in heavier situation. Higher gears for cruising, higher speed and lighter weight Reverse gear to move the vehicle backwards. Transferring the driving torque to the required wheels (Crolla, D, 2009, p, 109) The automatic transmission comes into two different types. The front wheel drives vehicles that are designed more compact than rear wheel drive vehicles transmissions that are normally connected in the engine compartment in which they are known as transaxle. Both of these types of transmission do the same job and same design of the planetary gear train. The essential part for the front wheel drive transmission is differential, while the rear wheel drive transmission has externally mounted differential which is uses the drive shaft to link up with the transmission. The automatic transmission system contains few major components. These are: Planetary gear unit Torque converter Hydraulic control unit Seals and gasket Computer Governor/ modulator The above six components perform various duties in transmission as explained below (Toyota technical training). Planetary gear unit: The purpose of planetary gear unit is to provide and changing different gear ratios. Generally, the planetary gear unit contains three major parts. These are ring gear, inner gear (sun gear) and planetary carrier that carries three or four gears which are between the inner gear and outer ring gear. Planetary gear unit When one part of the planetary gear connects to the input shaft which leads to the engine, the second part is held still and the third part usually attached to the output shaft. It all depends on which part stays still, which one is the input or output because it will result in different gear ratios. Things such as brake bands, hydraulic clutch packs and one way clutches are used in the planetary gear to control the power flow. Every gear links up to a combination of clutch packs and bake bands being engaged or disengaged (Samarins.com) Torque converter Is a fluid type coupling, that lets the engine to rotate freely without the help from the transmission, if the engine is running slowly, idling or on the stop traffic, there is a small amount of torque that is passed via torque converter, less pressure is also required on the brake pedal to keep the car stationary. Also when you put more pressure on the gas pedal, it speeds up and adds more fluid into the torque converter which causes the wheels to receive more torque. The torque converter housing contains five major components. Pump is fixed to housing, turbine that is connected through output shaft to transmission, stator has output that is connected to fixed shaft in transmission, fluid and converter clutch. This housing is attached to the engines flywheel and rotates and at any speed that the engine is spinning. The torque converter also has pumps that is made up of fins and are attached to the housing that uses the same speed as engine to turn. Centrifugal type pump is used inside the torque converter, as it rotates it causes the fluid to be thrown outside and this action creates the vacuum that draws a lot of fluid in at the centre. Once the fluid arrives in the blades of the turbine, the transmission begins to rotate and this causes the car to move, the turbines blades are curved and this makes the fluid that is coming from the outside to go into different way before it goes to the centre of the turbine, this changing of direction is the one that causes the turbine to spin. In other way we can put that both turbine and the fluid spin in different direction and this creates the force as an outcome. This fluid that exists from the turbine is usually moving into different direction as the pump and engine turn, because if the fluid hits the pump directly, it may cause the engine to waste power or slow it down and that is why there is a stator in the torque converter (Builders transmission and used car Inc.). Hydraulic control unit: A transmission fluid is sent using the engine oil pump that controls the performance of the car clutches that helps the planetary gear sets to work smoothly. Seals and gasket Their work is to support and maintain the right place of the engine oil and stop it from leaking outside. Governor / Modulator This controls and monitors throttle position and the speed of the car to determine when to change the gears. Computer This is the major unit that uses sensors to control all the activities such as engine speed, engine load, throttle position, brake pedal position etc. (Carazoo, 2010) 4. Materials The materials that are used to build clutch or transmission have to resist heat, friction, durable, strong, hard and tough. These materials are organic, Kevlar, segmented Kevlar, hybrid carbon, ceramic and sintered iron (UUC Motorwerks, 2003) 5. Advantages of automatic transmission system The torque converter gives more engine torques and reduces the strain and the shock of the entire drive line. A lock up clutch is included in the latest automatic transmission, this helps in maximizing the fuel economy because of its direct mechanical linkage from the engine to the transmission. A vehicle with automatic transmission is very comfortable and easy to drive as the driver does not need to manually change the gear ratios. Automatic transmission can also be powerful and strong because of the arrangement of the sun gear and ring gear, this increase the gears contacts that reduces the gears breakage and supplies more torque on big area (Rowe, R. 2010) 6. Disadvantages of automatic transmission Since the automatic transmission is made up of several components, the main setback can occur when single part breaks down working and this can cause a transmission to stop working, as a result maintaining or fixing it can be very expensive. Also the total speed of the vehicle is controlled by the computer that manages the transmission, and the driver can lose the acceleration beyond a certain speed. Automatic transmission can overheat easily. 7. Manual transmission system This is the type of transmission in which the driver has to manually change the gear ratio setting by using the gear stick inside the car. There are two types of manual transmissions. The constant mesh design and the sliding gear type. The sliding-gear type, no part is turning inside the transmission case except the main drive gear and cluster gear when the transmission is in neutral. In order to mesh the gears and apply engine power to move the vehicle, the driver pushes the clutch pedal and moves the shift knob, which shifts a linkage and forks to slide a gear along the main shaft that is connected straight above the cluster. Once the gears are meshed, the clutch pedal is released and the power from the engine is sent to the drive wheels. There can be different gears on the main shaft of different diameters and tooth counts, and the transmission shift linkage is designed so the driver has to unmesh one gear before being able to mesh another. With these older transmissions, gear clash is a problem because the gears are all rotating at different speed (Cook, M. 2009) The 5 speed manual transmission gear box has a three plane arrangement order with reverse gear alongside fifth gear and uses a special fluid to operate. Moving forks are attached to three wide base rails that work in arranged bushing for less friction, these moving levers are connected together to the shifting cables. Every one of them uses different way with selected lever and this creates less shifting efforts for a driver, it also avoids to accidentally engaging the reverse gear from fifth because of the way it is designed to operate, it shifts the crossover lever into three to four gear without jamming or binding. The shift knob is usually used to control the gear ratios. The forward gear ratios are synchronized using great capacity dual cone brass (1st and 2nd) and other gears are synchronized with paper friction materials which is more strong and clash resistant than brass. The input shaft uses paper materials synchronizers, by cutting rotating inertia it helps to reduce the shifting effort. A reverse engagement clash can be minimised by using a brake mechanism. The needle roller bearings are fixed to reduce friction and extend gear life. The case itself is cast in only two pieces to reduce leak paths; structural ribs strengthen and harden the case to reduce noise and vibration with small or no extra weight. The case has good bending stiffness, offering a natural frequency above the exciting frequency of the engine at peak rpm (Massey, K. 2010) 8. Clutch system A manual transmission system will not function without a clutch. This is the mechanism that is used for transmitting rotation that can be engaged and disengaged. This is controlled by the driver who uses a special release mechanism to control the movement of the torque between them. The clutch assembly A single disc clutch assembly contains four major parts: the rear face of the flywheel- a driving member the clutch disc- the driven member the pressure plate assembly-a driving member the release mechanism-disengages and engages the clutch (May, E. 2004. p,250) 8.1 Types of clutches Multidisc clutch that contain two or more disc are usually used in automatic transmission, motor cycles and heavy mechanical equipment. While the manual transmission is operated using a dry clutch and there is no lubrication between surfaces. The automatic transmission clutch operates wet, it is enclosed in the transmission case that is full of lubrication fluid. Generally, in automatic transmission there is no clutch pedal and a gear shift (Roymech, 2010) (Genta Morello, 2009 p, 425) There are so many different types of clutches such as cone clutches, wet clutches and dry clutches but the common one uses one or more friction discs that are pushed very tight together or against the fly wheel using a spring. A Clutch contains two rotating shafts, one is operated using pulley and the other one uses a different method, these two shafts are connected together by the clutch so that they can be locked together and rotating at the same time while it engages, or be decoupled and rotate at different speed while it disengages. The input shaft is used at the centre of the pressure to engage the splines of the friction disc hub. The clutch and flywheel assembly spinning as one unit when the engine is rotating. The flywheel is receiving the torque from the engine, uses the friction that is occurring from the clutch discs to the spline hub into the transmission. When the clutch pedal is moved, it manages and controls the movement of the torque between two units. The pressure pl ate can be retracted against the springs force and frees the disc from its clamping action by depressing the pedal. These two units and clamping force can be connected again by releasing the pedal once again. This is a very important mechanism when: Engaging the transmission into gear, the input shaft from the transmission must be disengaged from the engine. The pedal is released slowly, it provides a gradual engagement of the drive, as the facings slips of the friction slip, and this lets the torque to be applied continuously until these two units are connected very tightly. Choosing different ratio, changing gears when the vehicle is moving, for this to happen, the engine torque from the transmission must be interrupted. The disengaged of the transmission that causes the vehicle to stop and let the engine run at idling speed. The co-efficient of friction between the friction facings and their mating surfaces, the total spring force and the amount of facings in contact can decide the torque that is transferred by the clutch. If you want to increase the torque capacity, the diameter of the clutch needs to be increased and this will cause the spring force to increase. Multi plate clutch can be made by having two or more clutch plates as well as increasing the number of facings and torque capacity. They are useful where by reducing the diameter is beneficial or where by increasing the spring strength is undesirable. (CDX online eTextbook). 9. Advantages of manual transmission system The manual transmission vehicles are usually cheaper and good in maintenance compare to the automatic ones, this is because changing of the fluid can be very less, also when it breaks down it is more than likely that the clutch needs to be replaced and this can save you a lot from buying a new or second hand transmission. It gives better control because of the faster shift response, this is mainly due to the bad weather. They can as well be good in braking because the driver is not fighting the effort of the automatic transmission to move forward. It can be good is terms of fuel economy because you can shift the gear into neutral and avoiding driving in lower gears. A skilled driver at shifting gears will have a better traction in snowy, muddy or slippery conditions and might as well be easier to get of the dangerous situation than automatic one. Manual transmission is also lighter in weight. And there is a fun point of view in driving manual because it keeps you active and keeps you aware of what is going on around you (Moore, S. 2010) 10. Disadvantages of manual transmission system Driving manual car in traffic can be very pain full especially when there is a stop start driving, automatic cars are more comfortable in this case. It is very unlikely to find a manual transmission car with a cruise control. Most car now are built in automatic transmission so there is less availability of cars with manual transmission as well as the difficulties in learning how to drive manual transmission cars. 11. Report Summary This has been a successful report and I have researched a lot of information about this topic. Indeed I have acquired a lot transmission system. Here are some few pointed aligned below: History of the transmission What is automatic transmission system Major components of the automatic transmission and how they work Advantages and disadvantages of automatic transmission system What is manual transmission system Clutch assembly and clutch components and how they work Advantages and disadvantages of manual transmission system 12. Conclusions According to my understanding in the report, it shows the main difference between automatic transmission and manual transmission is that automatic transmission uses torque converter to create power while manual transmission uses clutch to engage and disengage the gears. Also automatic cars are in very high demanding since most of the components are controlled by computers now in the car. It also shows that once the automatic transmission breaks it can be very hard and complicated to fix it and this may end up in replacing the whole transmission. In terms of manual gear box, the report shows they are very hard to break or die as well as less maintenance too, this is one of the best things in manual transmission because it can last for long time without anything happen. From my point of view I would always recommend to go for manual car if you enjoy the gear changing ration as I do.
