Effects Of Technology In The Middle Ages - 1311 Words

The Middle Ages, and all of prominently configured ancient times differ from modern social traditions, relevantly due to the broad differenced in culture, technology, religious and sciences. The Renaissance Ages were moreover considered as the years of transition, where contemporary scientific discoveries were placed into affect, and enhanced political systems were inaugurated to battle against the â€Å"sovereign† yet malignant rulers who were determined to save their thrones in their Empires, and engaged in any remote, and localized conflicts to disable their opponents victories. New technologies were indeed in the revolutionary stages, and several new devices were founded by well contemplating scientists to ease the lifestyle of the everyday†¦show more content†¦The premier telescope was founded by Galileo in just one day, and the news of new cosmological galaxies ahead of our planet, â€Å"or the heavens† as ancient biblical scriptures denoted the phenomeno n of what is ahead of our planet.

The factual book was spread in multiple languages to read a expansive audience, to which is excelled in, and reached immediately publicity from highly educated persons, such as John Donne, a 1611 poet, who wrote the following describing the obscure documentation: â€Å"Galileo †¦ who of late hath summoned the other world, the stars to come nearer to him, and give him an account of themselves.† Though the news may be been prevailed as truthful upon publication, the text was seen as heretical, as it antagonized traditional Roman Catholic values, and contradicted beliefs of the revolution of the planets. The text was immediately banned, and all sales were terminated. For the remaining years, Galileo was tried on House Arrest, and was forced to remain in the vacancy of his home, and never depart from his residency for the remainder of his lifetime.

Pet Sounds vs. Rubber Soul Free Essays

Sha’rron Shelby Cynthia Bartles ENG 104 3/27/13 Essay two Final â€Å"Pet Sounds† vs. â€Å"Rubber Soul† Have you ever heard of the Beach Boys’ Pet Sounds and the Beatles’ Rubber Soul? If not I recommend that you listen to these albums, especially if you love someone. Speaking of these bands there are many differences and similarities when it comes to the love and the friendship that the artists between these two albums. We will write a custom essay sample on Pet Sounds vs. Rubber Soul or any similar topic only for you Order Now As you can tell the band members has been through many major things throughout their life. Also you can tell that both of the Beach Boys and The Beatles have been through many situations by the way their music is mixed up and by the way the performed during their concerts. From my point of view, I believe the Pet Sounds album was the best between the two albums because it was excellent. I can personally relate to the Pet Sounds album because I’m pretty much going through the same thing with my relationship. Now don’t get me wrong the Rubber Soul album was cool but there was a lot of love and affection, and the companionship that was demonstrate throughout the Pet Sounds album that makes me love it so much. Both of the bands have been through plenty of things throughout their lifetime. You can tell that the guys have been going through a cluster of things because of the lyrics and their music choice. Speaking of the albums, in Rubber Soul, â€Å"Michelle†, this song is all about being in love with a girl that is French. The lyrics explain that this man is absolutely in love with this woman and he is doing everything possible to show her that. He just wants to inform her that she has nothing to worry about and that he wants to be her everything. He always tells her that he loves her on the account of her being French and because the only words that she understands in English. This guy has proven that he is in love with this woman when he says: â€Å"I need to, I need to, I need to. I need to make you see,Oh, what you mean to me. Until I do I’m hoping you willKnow what I mean. I love you†¦ † I admire these lyrics because this man is trying his best to prove to this woman that he is really in love and he is going to do whatever it takes to get her to understand. However, I really dislike the beat that was made with this song. The beat and the way there were singing made it seem like there were not interested at all in the girl they were singing about.. But The Beach Boys’ took a different route with â€Å"Wouldn’t it be nice† The lyrics says: â€Å"Wouldn’t it be nice if we were olderThen we wouldn’t have to wait so longAnd wouldn’t it be nice to live togetherIn the kind of world where we belongYou know it’s gonna make it that much betterWhen we can say goodnight and stay together† And when I hear these lyrics I think of my own relationship because that is where I’m at in my life. The song has a very nice beat, with the guys singing so lovely and joyful. In this song he explains how he has either a close friend or a girlfriend and wants to make it where they can start living together so they can hold onto one another all day and night, wake up to each other and possibly get married. They don’t want to continue talking about living together; they want to make it happen. Both songs have good reasoning of showing they are in love with the person they are communicating with. I personally think both songs are amazing because they speak about real love in my eyes. But I liked the song â€Å"Wouldn’t it be nice† because it really shows a lot of love and affection and I can personally connect with the song. I can personally connect with the song because my boyfriend and I feel the same exact way when it comes to this song. On the Rubber Soul album, there is a song called â€Å"Wait† and it is very beautiful. This man has asked either his friend or girlfriend to wait for him until he had come home again. They have had some ups and downs, like regular couples do and he just wants her to wait for him. If her heart is still broken after all the stuff they been through, then he does not want her to wait for him. But if she can wait, he hopes that she will not move on and just wait for his return. In the song he says: â€Å"It’s been a long time, now I’m coming back home. I’ve been away now, oh, how I’ve been alone. Wait till I come back to your side,we’ll forget the tears we cried. But if your heart breaks don’t wait, turn me away. And if your heart’s strong, hold on, I won’t† I thought it was so wonderful. But it still leaves questions like why did he leave in the first place and where did he go? But I also want to know what made him want to leave knowing that he didn’t want to lose her. As the song plays, it sounds very exciting, but I just don’t like all of the instruments being used throughout this song. It’s like they were trying too hard to make something of the song. Besides, there is a song called, â€Å"You still believe in me† by the Beach Boys’. In this song a guy is probably not where he needs to be mentally or physically. He has done so much to this girl that she still shows him love and support. He has tried his hardest to be what she wants him to be but cannot help the way that he acts when she is not with him. In the lyrics he says: â€Å"Every time we break up, you bring back your love to me, And after all I’ve done to you, How can it be† As you can see, he has realized that he has done something very terrible to her a couple times and he is trying to figure out why does she keeps forgiving him and still believes in him. Now the instruments they have decided to use for this song is so perfect and relaxing. I really like how they changed their voice tones throughout the song from a high to low pitch. In both of these songs, you can tell that these guys have women that really love them and want to be with them. Even after all of the tears an heart break, they still want to continue lovely them so deeply and strong. But the song that I really enjoyed was â€Å"You still believe in me†. I really enjoyed this song because I can kind of relate this song to my relationship. At the beginning of our relationship, he was not mentally ready to settle down but after two months he settled down and was fully committed to me. Also there were a lot of things he didn’t believe in his self about but I helped him to start believing in his self because I believed in him. Speaking of both of the bands, they most definitely speak on the love for the woman they are in a relationship with. In the song â€Å"Caroline, No†, by the Beach Boys, the woman told him that she would never change herself and eventually she did. In the song he says, â€Å"Where did you long hair go, Where is the girl I use to know, How could you lose that happy glow Oh, Caroline no†, And by him saying those words, you can tell he is a little upset because she said that she would never change. As I listen to the song, I can feel the pain that he is going through, and know that he is very emotional. While you listen to the beat it’s very smooth and touching. In contrast, the song â€Å"Run for your life† has a very fast beat and it sounds very exciting. I’m surprised at the beat and the way they are singing because you would have thought they would have been very angry or would have had a very hard mean beat instead of a happy one. When he says, â€Å"Well I’d rather see you dead, little girl, Than to be with another man, You better keep your head, little girl, Or I want know where I am†, I feel so sorry for that girl that she even had to go through that tragedy. I couldn’t imagine a guy wanting to kill a little girl because she does not want to be with him. But back in the day, I guess those are the type of things that you would have had to expect. But it’s very sad because as we speak, now days many little girls lose the lives because they choose not to be with someone and the person felt like if you didn’t want to be with them then they don’t want you to be with nobody else. Then they will kill you so that you would not be able to date other people. There is some love in these songs but more of affection. It is crazy how guys think now days about how to be in a relationship and it still happens in today society. Most of all I really adore the song â€Å"Caroline, No† because you can feel that he is upset and he wants the old her back. As a final point, I really enjoyed the â€Å"Pet Sound† album the most because of the adoration, attachment, and friendship that was delineated throughout the album. But I can also say that I enjoyed the â€Å"Rubber Souls† album because some of the lyrics but it was the instruments that were used that I didn’t care for. Even though these people had hard times throughout their life as far as the love goes, they still made it and I hope they eventually found true love. There were many similarities and differences that were approached throughout these two albums because of the way they expressed their love and care for their woman. But both of the albums were really based on love. So back to the question I ask earlier, have you ever heard of the Beach Boys, â€Å"Pet Sound† album and the Beatles, â€Å"Rubber Soul†? After reading this essay I’m pretty sure you will want to look them up and get to know them especially if you are in love with someone. How to cite Pet Sounds vs. Rubber Soul, Papers

University of Chicago free essay sample

Each year, University of Chicago hosts a hunt; a one-of-a-kind only competition that asks college students to find over three hundred items in little more than half of a week. Although most schools make analogous demands on a day-by-day basis, University of Chicago’s stands out in that its list is not an index of textbooks. Its list is not a rubric. Its list is the â€Å"Scav Hunt.† As part of the hunt, U of C asks students scour the streets for a list of notoriously arbitrary items. Most recently, it has called for both sentient and slain bodily organs (#8 and #267, respectively); a forthcoming monarch (#66), and cowboy attire that is both vegan and vagabond friendly (#77). Just as U of C asks its students and faculty to push beyond the boundaries of intellectual impossibility, the competition asks teams to find the impossible—and just as Enrico Fermi’s ambitions fashioned the first artificial nuclear reaction, students return to campus in cars brimming with umbilical cords, elephants, and bee beards.

None but U of C could bring me that intellectual and interactional fulfillment that I have always longed for. None could even offer me the opportunity to write this—an essay based wholly off of a whimsical scavenger hunt.

The History of Juneteenth Celebrations

The History of Juneteenth Celebrations Abolitionists such as Frederick Douglass and Sojourner Truth worked tirelessly to free blacks from bondage in the United States. And when President Abraham Lincoln signed the Emancipation Proclamation on Jan. 1, 1863, it appeared that the peculiar institution known as slavery had met its end. For many African Americans, life remained the same, however. That’s because fierce racial discrimination prevented them from living autonomous lives. More shockingly, some enslaved African Americans had no idea that President Lincoln had signed the Emancipation Proclamation, which mandated that they be set free. In Texas, more than two-and-a-half years passed before slaves received their freedom. The holiday known as Juneteenth Independence Day honors these slaves as well as African-American heritage and the contributions blacks have made to the United States. History of Juneteenth Juneteenth marks the date of June 19, 1865, when Gen. Gordon Granger of the Union Army arrived in Galveston, Texas, to demand that the slaves there be set free. Texas was one of the last states where slavery endured. Although President Lincoln signed the Emancipation Proclamation in 1863, African Americans remained in bondage in the Lone Star State. When Gen. Granger arrived in Texas, he read General Order No. 3 to Galveston residents: â€Å"The people of Texas are informed that, in accordance with a proclamation from the Executive of the United States, all slaves are free. This involves an absolute equality of personal rights and rights of property between former masters and slaves, and the connection heretofore existing between them becomes that between employer and hired labor. The freedmen are advised to remain quietly at their present homes and work for wages.† Following Granger’s announcement, the formerly enslaved African Americans broke into celebration. Today that celebration, said to be the oldest black American holiday, is known as Juneteenth. African Americans not only celebrated their freedom, they exercised their new rights by buying land across Texas, namely Emancipation Park in Houston, Booker T. Washington Park in Mexia and Emancipation Park in Austin. Past and Present Juneteenth Celebrations The first massive Juneteenth celebrations kicked off the year after Gen. Granger appeared in Galveston. Historic Juneteenth celebrations included religious services, readings of the Emancipation Proclamation, inspirational speakers, stories from former slaves and games and contests, including rodeo events. Many African Americans celebrated Juneteenth in the same way that Americans generally celebrate the Fourth of July. Today, Juneteenth celebrations feature similar activities. As of 2012, 40 states and the District of Columbia recognize the Juneteenth holiday. Since 1980, the state of Texas has observed Juneteenth as an official holiday known as Emancipation Day. Contemporary celebrations of Juneteenth in Texas and elsewhere include parades and street fairs, dancing, picnics and cookouts, family reunions and historical reenactments. Moreover, President Barack Obama pointed out in his 2009 proclamation of the holiday that Juneteenth â€Å"also serves as a time for reflection and appreciation, and an opportunity for many people to trace their family’s lineage.† While African Americans widely celebrate Juneteenth today, the popularity of the holiday has waned during certain periods, such as World War II. Holiday celebrations of Juneteenth resurrected in 1950, but by the last years of that decade and in the 1960s, Juneteenth celebrations declined once more. Juneteenth became a popular holiday again in a variety of regions during the 1970s. In the early 21st century, Juneteenth is not only a well celebrated holiday, there’s a push to have the 19th of June become a National Day of Recognition for slavery. Call for National Day of Recognition The Rev. Ronald V. Myers Sr., founder and chairman of the National Juneteenth Holiday Campaign and the National Juneteenth Observance Foundation, has asked President Barack Obama to â€Å"issue a presidential proclamation to establish Juneteenth Independence Day as a National Day of Observance in America, similar to Flag Day or Patriot Day.† As an elected official in Illinois, Barack Obama supported legislation for his state to recognize Juneteenth, but the president has yet to make a move that would make Juneteenth a National Day of Recognition. Only time will tell if Juneteenth and the slavery of African Americans is ever acknowledged by the federal government in such an official capacity.

Inverted Pyramid Method of Organization in Newswriting

Inverted Pyramid Method of Organization in Newswriting The inverted pyramid became a standard form in American newspapers early in the 20th century, and variations on the form remain common today in news stories, press releases, short research reports, articles, and other forms of expository writing. It is a method of organization in which facts are presented in descending order of importance. Examples of Inverted Pyramid Composition The concept behind the inverted pyramid format is relatively simple. The writer prioritizes the factual information to be conveyed in the news story by importance. The most essential pieces of information are offered in the first line, which is called the lead (or summary lead). This usually addresses the so-called five Ws (who, what, when, why, and where). Thus, the reader is able to ascertain the key elements of the story immediately. The writer then provides the rest of the information and supporting contextual details in descending order of importance, leaving the least essential material for the very end. This gives the completed story the form of an inverted pyramid, with the most important elements, or the base of the story, on top. Opening With the Climax If the essence of the story is its climax, then a proper inverted pyramid places the storys climax in the lead or opening sentence. The most important elements of a well-written news article thus appear in the lead, the very first sentence of the story. Cutting From the Bottom The inverted pyramid style in newspaper writing was developed because editors, adjusting for space, would cut the article from the bottom. We can write the same way in a magazine article. . . .We add details as we enlarge the article. So the weight is like an inverted pyramid, with the details of lesser importance at the end of the article.For example, if I write, Two children were injured when fire swept through the First Community Church, Detroit, Michigan, on May 10. The fire is believed to have started from unattended candles. Thats complete, but a lot of details can be added in succeeding paragraphs. If space is tight, an editor can cut from the bottom and still save the essential elements. Using the Inverted Pyramid in Online Writing The inverted pyramid structure, typically used in newspaper writing, is also appropriate for long narrative text in online technical documents. Use this structure to organize paragraphs and sentences within a section of narrative text. To create an inverted pyramid structure, follow these guidelines: Use clear, meaningful headings or lists at the beginning of a topic.Create separate paragraphs or topics to emphasize important points.Do not bury your main point in the middle of a paragraph or topic.

Family on Film Movie Review Example | Topics and Well Written Essays - 250 words

Family on Film - Movie Review Example Atticus is a lawyer who does not bend his ideals and principles. Though everyone was discouraging him to defend a black man—because he is already guilty by the mere color of his skin, he was determined to prove the innocence of Tom. Although it was a very unpopular decision, a white man defending a black man accused of raping a white woman, Atticus stuck by his principles; undeterred by the social pressures caused by his unpopular decision. Although he successfully defended Tom and proved his innocence yet lost the case, his social defiance sent a very powerful message to his children. Unlike Atticus, Antonio of â€Å"The Bicycle Thief† was someone who wanted to stay true to his principles but failed to do so due to social pressures. Like Atticus and all decent fathers, Antonio also wanted to provide for his family to the best of his capacity. That is why the bicycle is symbolic in so many ways—income, dreams, hope, escape, and security among others. But because Antonio was hard-pressed in all possible ways, he no longer could stand-by his morals. In the end, he opted to steal a bike, and ended up embarrassing himself not just in front of the whole community, but in front of his son.

Coursework in Arts Essay 1. In Elisabeth Vigee-Lebrun’s painting of the Queen of France, Marie-Antoinette, in the late 18th century, the queen is shown sitting with her three children in a formal gown at the edge of the Hall of Mirrors. Colors that were used can be described as basically feminine—shades of ruby, cherry, velvet, scarlet, and salmon; yet darker colors were used in the crib of the eldest son to portray his death. From the colors of the painting, the queen appears to be sitting on a shiny spot, but around her is a darker, gloomier color that may portray danger to her and her children. Textures, on the other hand, appear to be soft and feathery, which shows wealth and comfort. The lines in the background are parallel and horizontal, which points to her straight, firm position in her seat. The position of the queen and her two children beside her form a straight cross beside the crib that looks like a cave. The eldest son alive who points to the crib may appear like the angel beside the cave where Jesus was buried. The son was like saying, ‘You’re looking for my brother? He’s not here anymore but has gone up to the Father. ’ On the other hand, the eldest son alive stands firmly alone, which shows independence and strength†¦even at an early age. The stairs in the background may mean political fame, but it was portrayed to be darker and more shadowy above, so that it would be best for the queen to be where she is—with her children and her home (please see painting in the appendix). Formal elements show that this good queen is a devoted mother—full of quiet dignity—by the way the colors, the textures, the lines, the shapes, and the space interact with one another. The whole scene portrays quietness, peacefulness, as well as acceptance—things that picture her as a good and pleasant being. There is also the hint of wealth and extravagance, especially the portrayal of the Hall of Mirrors. In the overall, the painting is meant to give her a positive, submissive, and motherly aura. 2. John Singleton Copley’s painting of Paul Revere in 1768 is an example of a Rococo painting. The Rococo style, which emerged in France, characterizes opulence, grace, and lightness, as seen in the painting (Figure 2 in the appendix). Copley used contrasting colors like black (as the background) and white (as Revere’s shirt) to put more emphasis on the main object. The lines, colors, and objects are all simple. Lines, especially in the head and in the table, are all parallel, which may point to neutralism and evenhandedness. It was said that Revere was â€Å"uninterested in politics; he wanted only to be neutral, which was not possible† (Artchive, 2007). The eyes, on the other hand, portray innocence, knowledge, and fairness. The textures used are all smooth and shiny, which may also reflect opulence. It focuses on ‘carefree aristocratic life’, with direct reference on Revere’s being a silversmith—with a piece of silverware on his hand. He was portrayed with such extravagance, as shown in the linen cloth, which at that time was not yet available in America and could only be imported to the land†¦ as well as the golden buttons that lay on his vest. However, the portrayal of ‘flowing linen’ could point—not to the linens of England—but to the production of a hundred ells of linen in America during that time, which for Revere was something to be proud of. However, it is said that the painting is a sort of a ‘balancing act’ conducted by painter Copley (Artchive, 2007), especially that he is about to marry one of the Clarkes who were owners of â€Å"the notorious tea concession† (Artchive, 2007). The silver teapot appears to be a large issue then, since only their enemies—the Tories—drank tea (the Whigs drank the Boston tea, which was a punch). Revere is shown as a neutral person who wears rich linen clothing, but which comes from his own land. He is holding a silverware teapot, which is one of his expertise, but points to the character of the enemies and to the business of the Clarkes with which Copley is about to share his life with. Therefore, Revere is neutral, as he is open to all.

Canterbury Tales Comparison :: essays papers

Canterbury Tales Comparison "If gold rusts, what shall iron do" (502)? This question seems to be the basis of the comparison between the parson and the reeve. One, a good man on the inside and out, the other, a wonderful fascade to hide his true personality. Althgough completely different, one tries to imitate the other to make himself appear a good man. The parson embodied what a preacher of the Lord should be. He was honest, kind, truthful, "benign, and wonderfully diligent" (485). Although he was a righteous man eh did not belittle or condemn those who were not as holy as he was. However he woudl highly scold those who were "obstinate" (523). He was a man who practied what he preached and led people not by his words, but his good actions. He would even give the poor parishoners some of his own moeney and possessions. He felt that it was imporrible "to find a filthy shepherd and a clean sheep" (506) and that if he was a priest (a man who is closer to God than most) is corrupt, then how could he expect his parishoners to be honest? There is no counter representation for the parson because with all of the good deeds he has done for others, when Chaucer says he believes "there is not better priest anywhere" (526) he believes it to be true, and so does the reader. The reeve was a thin, "choleric" (589) man. He was very clever and wilely, and could not be tricked by other. He was very knowledgable about about predicting what the yeild of his crops would be. Most people were afraid of him and he had a plesant home in a meadow. It would seem that he would have a sort of unhappy dreary home, but that was not the case. A lot of his master's properties were under his control and power, and he tricked his lorfd into getting most things. He would lend and sell the lords own properties back to him, and he privately had more riches than his lord. He also learned the trade of being a craftsman and a carpenter at a young age. However wicked the reeve may be on the inside, he tries to make others see him as a good man.

Introduction of Tourism Essay

God’s earth in all its fullness and beauty is for the people, Thomas Cook Yes god’s earth is very charming and beautiful ones. Travel from the ancient time has held a fascination for mankind . The urge to explore new places and seek a change of environment is not new. In all the epics whether it is â€Å"The Ramayana’’ or â€Å"The Mahabharata† or â€Å"The Bible† every where travel has been mentioned. nly reasons were different. Somewhere travel was to escape from one to another because of cruel king and somewhere it was because of parent’s order or a condition in gambling . But there is no doubt that rapid development in the means of transport and communication has made the whole world practically one neighborhood and has made travel an easy affair. â€Å"Tourism is fourth Extension of Modern Economics† Frayad According to a study Conducted by the Wharton Econometric Forecasting Associates (WEFA group ) on behalf of the American Express Travel Related service company â€Å"Travel and Tourism is the largest industry in the world in terms of employment in almost every country of the world† The study further points out that â€Å"Travel and tourism employment investment output and value added exceed those of such major industries as steel automobiles textiles and electronic in Virtually every country† The estimates about tourist says that the numbers of tourist leaving their homes is 694 millions in 2001 and this number likely to swell to 1600 millions by 2020 and the receipts from it are estimated to Cross $ 2000 billion. One of the leading futurologists in the world Hermann Khan Predicting a golden era for tourism says â€Å"In sum I see a very bright future ahead for tourism and travel industry. There are clouds on the horizon to be sure but †¦.. it will become a larger giant than it already is in the next 50years. Today the benefits of tourism are not to be judged in terms of economic enefits alone Tourism has wider implications encompassing not only economic benefits but also social and cultural benefits as well. From the social and cultural point of view there is enough evidence to support the fact that tourism and travel unquestionably produces an interaction between the cultural customs of the visitors and those of the host population. Cultural tourism is a fertile g round for exercising creative talents, festering special kinds of relations between the visitors and the host population between the tourists and the host environment. The economic benefits to a country by way which of earning foreign exchange on the other hand are however the prime motive for various nation to promote tourism Those responsible for managing the affairs of nations have almost universally recognized the economic advantages of tourism . Tourism is an important sources for maximizing scare foreign exchange earning for not only the developing countries but of many developed countries of the world as well. In short the tourism phenomenon has attracted almost the entire world. Those responsible for managing the affairs of nations have almost universally recognized the economic advantages of tourism . Besides economic benefits to a country by way of earning foreign exchange and employment generations. Tourism also makes a tremendous contribution to the improvement of social and cultural trends of the country. Tourism emerged as the largest global industry of the 20th century. In the new millennium global economy will be governed by technology, telecommunication and tourism. Tourism has potentials to create the maximum numbers of jobs. According to an assessment, in India alone 100 million additional jobs will be created by the tourism industry in the next 25 years. It helps to earn valuable foreign exchange also. We should always remembered that development does not mean increase in GDP and GNP alone. It must add to prosperity and happiness. An important feature of the tourism industry is its contribution to the National integration and creation of harmonious social and cultural environment. It also encourages respect for preservation of Monuments and Heritage properties. It should help the promotion of arts, crafts, culture and bring a prosperity and sustainable development. Thus contribute to the creations of prosperous, healthy and peaceful world. By 2020, tourism is poised to be the single most important influence on global trade and commerce. Tourism is an economic activity and every activity depends on demand. Tourism also creates demand from its activities and we cannot ignore its importance in economical growth. Tourism is related with many industries also. Tourism plays an important role in enhancing jobs opportunity. According to Jag Mohan, ex- tourism ministers of India ‘On 10 lakh investment only 12 persons can be employed in any industry, but tourism industry can employ 47 persons on the same investment. † It is also believed that in INDIA only tourism is providing direct job opportunity to 93 lakh persons. The activities involved in travel and tourism industries are accommodation, transportation, restaurant entertainment and other services related with travel. The effect of improvement in travel and tourism is on travel and tour economy and hence whole economy. One more important fact that more employment opportunity can be speedily generated on lower costs. These opportunities are at small industries and local community level. These years there is tremendous like in tourism of all over the world. Even tourism has got the status of largest export industry of the world. There are only 16,800 foreign tourists in INDIA in 1951, which has increased to 1. 7 million in 1990 and further increased to 2. 75 million in 2003. The growth rate of tourism between 1990 to 2000 was 4. 46 percent annually. The growth rate achieved in year 2000 was much more than that of previous year. But if compare it with respect to tourist arrival, than share of India in world is constant at 0. 38 percent from 1995. In south Asia India has share of 42 percent of foreign tourist’s arrival in year 2000. It means that tourism growth rate of INDIA is 4. 7 percent as compare to 3. 2 percent average growth rate of the world in the time span of 1995-2000. But the Indian tourism growth rate of 5. 3 percent in 2000 was very little with compare to our neighboring countries like China (15%) , Hong Kong (10. 7%), Malaysia (27%), Thailand (12. 5%) , Makau (25%), Iran (28. %) . NATURE OF TOURISM : The term ‘tourism is used to describe the temporary short –term movement of people to destinations out side the places where they normally live and work. The word ‘TOUR’ has its origin from the Latin term ‘TORNUS’ which means lathe or wheel. The full turn of the wheel or lathe forms a circle or a circuit lust like this tour involves the process of a jou rney in which one returns to the starting point. The word ‘tour’ it is noted was first used to refer a journey in which one travels and visits a number of places in a circuit. A tourists leaves home to get away from routine grind but the end of all is that he is only eager to go back to his sweet home’ (Robinson, 1976) â€Å"Tourism is travel and visiting places for pleasure often involving sightseeing and staying in overnight accommodation. Regarded as an industry, tourism can increase wealth and jobs opportunities in an area although the work is often seasonal and low paid among the negative effects of tourism are traffic and people congestion as well as damages to the environment† (Hutchinson, 2002) Journey effected for pleasure and holiday, health business and trade, pilgrimage and social purposes, studies, training and research, foreign affairs and other similar purposes are covered under tourism. Tourism provides business for travel agents, transporters, hotels, retailed dealers and many others. It is a direct product of technological and scientific progress associated with industrialization ,urbanization and population explosion (Sarngadharan, M 1995) Travel and tourism has come to occupy a Prime position in the global economy. It generates foreign exchange to a considerable extent, boosts the economy and promotes peace and understanding between different countries. Tourism is an industry which has a social phenomenon with economic consequences. It gave a number of social and economic benefits. Leaving about the cultural diversities and lifestyles of different people helped in promoting international brotherhood as the millions who travel all over the world really build up on ethos of integration and relations. It is conglomeration of various industries and related activities forming a single entity and generates employment in a big way. There is no doubt that over the past two decades tourism has become one of the fastest growing industries in the world. For the collection of statistics it is usually necessary to determine a boundary which must be crossed by travellers if they are to be enumerated as tourists. This is frequently though not necessarily an international boundary Motivation to travel is many and varied and complicate the enumeration problems. Business travelers are usually included, while students abroad are excluded from most international tourist statistics. International tourism is dominated by the western world which constitutes both the major source of tourists and the most frequented destination areas (Williams and Zelinsky, 1970) . This feature of tourist flow is largely explained by the relatively high incomes of the western world which permit the luxury of the long distance movement and the availability of efficient transportation and superior accommodations which facilitates travel in comfort. Several developing countries possess the attraction of warm climates, interesting landscapes and cultural and low living expenses. Reduction in the costs of long distance travel has put them within reach of the more prosperous traveler in the western world. The large sums of money involved in international tourism have attracted the attention of many developing countries eager to gain a larger share in the expanding tourist trade. Tourism is seen as a source of income, foreign exchange, jobs and amenities for the resident population (United Nations Conference on Trade & Development, 1973) It may help to diversify economies, provide a stimulus for the development of other industries and contribute to the dispersal of economic activities. However it would be wrong to assume that tourism is a panacea for the economic ills of the developing world. In many cases tourism has been a mixed blessing and economic gains have only been achieved at social and environmental costs. Even the economic benefits have been over estimated. But this is particularly the where development has been based upon foreign capital imported labour and materials, generous tax incentives and expatriated profits. Tourism and recreation must be planned as carefully as any other industry should be minimized if maximum benefits are to accrue to the reception area. In India the travel and tourism industry has really come of age . India being one of the most sought after destination in the world the potential of the industry as a foreign exchange earner is well known. Being an employment –Oriented and labour – intensive industry and set to become number one in the world in these aspects. It provides high growth prospects for specialists. The industry is and has always been a good employer and pay packets are promising. Tourism is accorded the status of industry because investment is required for the infrastructure, it employs labour and profit is recorded. The significant feature of the tourism industry is that it employs a large number of women – educated, uneducated, skilled or unskilled, generate employment opportunities particularly to remote and backward areas and also contribute to national integration. Women actually outnumber men in hotels, airline services, travel agencies, handicraft and cultural activities. The tourism industry is a limitless industry with immense growth potential the world over. Tourism has a tremendous positive impact on the economic and social aspects of the host country. To reap the economic and social benefits of tourism countries are vying with each other to woo more international and domestic tourists. India is no exception, though to its achievements are not astonishing. It is very necessary to have a clear concept and more precise definition of tourism for more insight about the tourism. Tourism is a painless procedure for transfer of real resources from industrially capital surplus developed countries to low income developing countries. It is very important source not only maximizing scare foreign exchange earning not only developing countries but many development countries.

Marxism vs Functionalism

As a sociological discipline, functionalism is counterposed to Marxism. However it shares with Marxism the importance of ‘totality’ and the corresponding view that scientific inquiry is based upon the interdependence of parts within a whole. It is important to distinguish why the Marxian use of the totality differs significantly from functionalist systems. Primarily this involves the Marxian emphasis on the contradictory character of the whole and the treatment of the social totality from the perspective of its conflicts.Functionalism in contrast views society generally as a stable system and looks for the mechanisms that give it harmony – it thus seeks to reduce conflict to a residual element of the system, or view conflict from the perspective of its maintenance of the social system. Marxism was founded by Karl Marx. Marx saw society as divided into two major parts, the economic base otherwise known as the infrastructure and the super-structure. Functionalists s ee society as a set of parts which work together to form a whole. Functionalism is also called a consensus theory.Marxism and functionalism are similar in that they see that the way society is structured as an important part in determining the way people have relationships and behave between themselves. This is known as structural perspective. Both functionalists and Marxists believe that people are portrayed as creature within the social system. Functionalists believe that society operates to the benefit of everybody. They stress that societies continue to exist because a lot of the time there is consensus between various aspects.

Causes of Conflict

Scarce resources are very important to the country. It is a source of revenue for the country and it can be sold off for money and as raw resources for industrialization. Thus, countries would want to compete for scarce resources. An example would be the Iceland-britian conflict. As Iceland depends on the fishing industry for survival, its source of revenue comes from the fish caught. In 1970s, the number of fish, especially cod, dropped by 1/3 and these were due to the over fishing of Belgium, german and britian on Iceland seas. Thus, Iceland has came up with measures in controlling the number of fish caught to the UN but most were ignored. As 79% of the total export comprises of fresh fish and fish products, it is important for Iceland to maintain a sustainable levels of fish stocks in the seas around Iceland. Source of economic survivals is threatened, Iceland had to fight to ensure that this source of natural resource is sustained. This conflict resulted in Iceland breaking displomatic ties with britian. When a country’s scarce resources is being threatened, they have to fight back as it is their main source of revenue and survival. Losing the main source of scarce resource ewould lead to economic downfall, jobs and livelihood at stake resulting in poverty Different values and benefits. Countries fight over different values and benefits due when they feel that it is being threatened by others. This is evident in the Korean war. Korea is being separated into 2 halves in the 38th parallel after the Japanese surrended in the 1945. The Russian occupied the north of parallel and the American occupied the south of parallel. Attempt of un to establish a single government failed as the north parallel did not want to have an election in the north. North korea was then created and became a communist party whereas south korea was then created and became democratic party. Both the government claimed that they both have the rights to rule the Korean peninsula. China, afraid that the north korea would be influenced by the south korea’s democractic system, helped and supported north korea in the war of north korea and south korea to spread communism. This showed that when countries come into conflict to extend their balue systems to other territories and also protect their value systems from being threatened to fight back

What kind of adjusmnets hospital CEO must make to meet helath reform ( Essay

What kind of adjusmnets hospital CEO must make to meet helath reform ( ACA) requirements - Essay Example This paper indicates the possible actions that a hospital CEO would undertake to tackle the challenges and take advantage of the opportunities the Act presents. It is divided into six sections that are meant to answer the question. Likely questions that a hospital CEO would ask him or herself include how the Act will be applied to the hospital, what the Act means for his or her hospital and what strategic concerns should be regarded to prosper in the environment resulting from the Act. The Affordable Care Act is composed of resources and plans to manage growth local, federal and the state workforce. The Act offers loans and grants for persons, hospitals, organizations, and schools. Those who are mainly targeted are those who have interest in low earnings and in the countryside. The Act maintains the number of graduates taking medical courses who are funded by Medicare. It has provisions that allow the redeployment of slots that have not been allocated to anyone. Redeployment of closed hospital slots is aimed at exploiting healthcare resources and prospects in training (Main & Starry, 2010). When the aging workforce is considered with the demand for services in healthcare, especially if the general population is made up of a large number of old persons, then this raises a great concern for hospital CEO’s. Who will take care of this ageing population if the general healthcare workforce in the hospital is ageing? Healthcare professionals and workers above the ages of 55 are regarded as part of an ageing workforce. As the hospital CEO, one will seek to take advantage of the Act and seek the grants that it offers. These grants will then be used by the hospital to sponsor bright needy students undertaking medical courses in institutions around the country. The terms for sponsorship shall include provisions which shall ensure that sponsored students will work for the hospital in return for a period of not less than ten years. This way, the

The Women Essay Example | Topics and Well Written Essays - 500 words

The Women - Essay Example She begins to critically examine her life and her relationship with men and the people around her. At some point, she considered divorce, and this would have not only affected her but also their daughter. This play thus helps to remind the audience that although one might appear to lead a happy and comfortable life, problems in marriage can make life bitter. Friends and family play a vital role in resolving such domestic problems. The intent of this production, in my view, was a good idea. This play speaks to everyone; the married and the unmarried. It helps us examine our families, our actions and how best we understand the people around us. There are two main issues raised in the play that make it important and applicable. First, through the life of Heines and the unfaithfulness of her husband, the play reminds us of the importance of safeguarding marriages and building strong family ties. The suffering brought to Haines through her husband’s infidelity is traumatizing. The play further highlights the need to solve domestic or marital problems without taking rush decisions. Secondly, the play helps us re-examine the role played by our friends in our lives. In the play, Selvia knew that Heines’ husband had an extramarital affair yet she did not inform her friend about it. She instead spread the rumor among other women. This play thus allows the audience to examine whether or not to keep some of their friends. In particular, this play reminds us of the role friends play in marriages. Overall, the play challenges and provokes the audience. The intention is to make people examine their behaviors, beliefs and their general view of life. This play succeeds in provoking us into asking ourselves questions regarding our lives, and how we treat those around us. After watching the play, I believe that the play achieved its purpose. First, in a good play, characters need to portray the events as real as they possibly can. In this play, the characters portrayed

An analysis of two engineering Forms of Contract Coursework

An analysis of two engineering Forms of Contract - Coursework Example These benefits are in terms of cost b saving, improvement of quality of both services and products, and time-saving. The very first NEC contract was published in 1993. The abbreviation NEC stands for New Engineering Contract. This new type of engineering contracts was a radical shift from the traditional contracts that existed before the year 1993. Unless the previous contracts, this contract is written in plain language. The contract abandoned the frustrating nature of the previous engineering projects and concentrates on stimulating the parties involved. After the first edition of NEC contract, the second edition was published. This new edition was called the NEC Engineering and Construction Contract. This was only two years after the NEC contract was published. This new NEC contract had Adjudicators Contract, a new professional service and subcontracts together with a set of back-to-back short forms. In April 2013, this suite was enlarged and updated. The new move saw the total number of documents making it rise to 39 documents. These documents included Professional Services Short Contracts and a set of enhanced guidance documents. The professional services short contracts are the standard form used to appoint project managers by the Association of project Management. The updated NEC contract is called the NEC3. The NEC3 is recognized worldwide for its unrivaled track record. This has seen it getting endorsements from both industry and governments all around the world. Some of the major engineering projects that have been delivered by this contract within budget and on time are the venues for both the 2012 London Olympic venue and the Paralympic games venue. This projects put the NEC3 onto a whole new level. FIDIC’s standard form of contract is much older than the NEC3 contract which is quite recent. This type of contract is

Series Pass Voltage Regulator From Discrete Electronic Engineering Essay

Series Pass Voltage Regulator From Discrete Electronic Engineering Essay The objective of this project was to construct and design a 9V  ± 0.3V, 1A series pass voltage regulator from discrete electronic parts. The voltage regulator must exhibit a voltage regulation of 5% or better and should be supplied with a dc input voltage. The regulator circuit was required to include a way to disconnect the load from the regulator if the load current exceeded 1A or if the temperature of the series pass element exceeded 40 °C. It was necessary to measure each parameter of the circuit and convert it from an analog to a digital signal. This signal would provide data necessary to display the values on the Spartan III FPGA Development Board. The numerical display was not to have any zeros leading a number, unless it affected the value. Also, the display was to be cyclic, alternating at 5 second intervals. The circuit was designed, built and tested. It produced 9.03V output and 1.02A through a 9à ¢Ã¢â‚¬Å¾Ã‚ ¦ load. The cut-off protection worked as well as the variable sensing circuitry. The linkage of the analog and the digital components, however, remain incomplete. Contents LIST OF FIGURES LIST OF TABLES LIST OF ABBREVIATIONS AND SYMBOLS Symbol Description ADC Analog to Digital Converter Op-amp Operational Amplifier V Voltage/Volts I Current R Resistance A Ampere à ¢Ã¢â‚¬Å¾Ã‚ ¦ Ohm  °C Degree Celsius F Farad IC Collector Current IB Base Current VBE Base-Emitter Voltage LUT Look Up Table BCD Binary Coded Decimal MUX Multiplexer CLK Clock DPDT Double Pole Double Throw FPGA Field Programmable Gate Array Table : List of Abbreviations Contained in this Report INTRODUCTION Commercial power is usually distributed with an AC supply. An unregulated voltage such as this could cause damage to many household appliances and electronic devices. Therefore it is a safety hazard. A voltage regulator is a device that maintains a relatively constant output voltage for a varied input voltage. It functions by comparing the output voltage to a fixed reference and minimizing this difference with a negative feedback loop. The aim of this project to design a series pass voltage regulator with an output of 9  ± 0.3V and regulation of at least 5%. It should be able to disconnect the load from the regulator for temperatures exceeding 40à ¢Ã‚ Ã‚ °C and a current greater than 1A. Using A/D converters, these values (output regulator voltage and current, temperature of the series pass transistor) were converted to digital format and displayed on the Spartan III FPGA Development Board. Each value received from the analog component should be displayed with no unnecessary leading zeroes. The display had to alternate between different variables of voltage, current and temperature. The Digital Component of this project was designed in Xilinx ISE 7.1i, and the necessary tests were carried out. A User Constraints file was created, which allowed for the programming of the FPGA Board. BACKGROUND THEORY AND LITERATURE REVIEW Using an unregulated power supply is unfeasible for most tasks. This is because as the load current increases, the ripple voltage increases and the DC output voltage decreases. The voltage regulator greatly reduces ripple and produces a steady output voltage for a range of input voltages. Different types of voltage regulators have different functions. There are two main types, shunt and series voltage regulators. Shunt Voltage Regulator For a shunt voltage regulator, the regulating device is placed in parallel with the load. A resistor is placed in series with the load and the unregulated supply. The current is varied through the control element depending on the load current. This causes a voltage drop across the resistor in series, maintaining a constant load voltage. (Prof. Gift, 2012) Figure : Shunt Voltage Regulator Shunt Voltage Regulator Example: Zener Diode Regulator Figure : Zener Diode Voltage Regulator The zener diode is a semi-conductor diode designed to operate in the reverse-biased region. In forward bias, it functions as a normal diode but when in reverse bias, it breaks down for voltages exceeding the breakdown voltage, or zener voltage. For operation in this region a current Iz is required where the limits being the minimum and maximum current for the diode to operate without breaking down. (Prof. Gift, 2012) Series Voltage Regulator For a series voltage regulator, the regulating device is placed in series with the load and the unregulated supply. (Prof. Gift, 2012) The output voltage is sampled by a circuit that provides a feedback voltage to be compared to a reference voltage. If the output voltage increases, the comparator circuit provides a control signal to cause the series control element to decrease the amount of the output voltage, thereby maintaining the output voltage. If the output voltage decreases, the comparator circuit provides a control signal to cause the series control element to increase the amount of the output voltage. (Electronic Devices and Circuit Theory 7th Ed.) Figure : Series Voltage Regulator There are different circuit topologies for the series voltage regulator. These will be examined next. Simple Series Transistor Regulator To improve the current capacity of the zener diode regulator, a transistor is used in the emitter follower configuration. This acts as the series control element. The collector is supplied by the regulated voltage. The transistor reduces the load current capacity of the zener by a factor of the transistor current gain. The zener voltage is therefore produced at the emitter. The equation IC = ÃŽÂ ²IB is used to link the collector current and the base current. Due to high current gain, even very large changes in IC result in only small changes in IB. This means IZ is mostly stable. The input voltage must be greater than the diode voltage to ensued proper transistor bias. (Prof. Gift, 2012) Figure : Simple Series Transistor Voltage Regulator IZ current through the zener diode IC collector current IB base current Discrete Voltage Regulator A transistor Tr2 is connected as the series pass transistor and another one Tr1 acts as the error amplifier. In the single transistor regulator output ripple voltage is low, but the output voltage still varies. This is due to the VBE/IC characteristic of the transistor. Feedback is used to correct the output. This amplifier compares the sampled voltage with a reference voltage in order to generate a signal proportional to the difference. This is used to drive the series pass element, which then varies the output voltage such that the error is reduced and the output voltage regulated. Figure : Discrete Transistor Voltage Regulator The voltage across the series element is (Vin Vout). The input voltage to the error amplifier is ÃŽÂ ²Vout Vref, where . The output voltage across the series element is an amplified version of the input voltage, . If Vref is constant, . This is the stability factor. This means that the ripple voltage is reduced by a factor of . The higher the loop gain, AÃŽÂ ², the better the regulator performance. A is gain of error amplifier. The resistor R can be connected to the regulated side of the circuit to improve the design and decrease ripple voltage. Also, a capacitor may be placed in parallel to the Zener diode. Another capacitor can be placed across the output removing output noise and input impedance at high frequencies. A Darlington Pair may be used as the series element. This has two transistors in a single package. The Darlington Pair increases the current gain of the series element, making it able to supply a larger load current if required. (Prof. Gift, 2012) Operational Amplifier Series Voltage Regulator In order to improve the regulator performance, the loop gain A is increased. A simple method of doing this is to replace the transistor error amplifier with an operational amplifier as shown in figure 6. The operational amplifier compares the reference voltage of the zener with the feedback voltage sampled by resistors R1 and R2. The Darlington Pair design is used here and R3 connected to the regulated supply to reduce the ripple voltage. The operational amplifier (op amp) must be supplied by the unregulated input voltage. (Prof. Gift, 2012) Figure : Operational Amplifier Series Voltage Regulator STANDARDS Certain standards were considered in the undertaking of this project.

DESIGN APPROACH AND METHODOLOGY Project Requirements: Design and build a 9V  ± 0.3V, 1A Series Pass Voltage Regulator using discrete electronic components. Regulator must have a voltage regulation or 5% or better and must be fed by a dc input voltage from a laboratory power supply. In addition, the regulator must incorporate temperature and over current sensing circuits which would disconnect the load from the regulator, for temperatures and currents exceeding 40 degrees centigrade and 1 A respectively. The output regulator voltage and current, together with the temperature of the series pass transistor must be converted to digital format using A/D converters and displayed on the Spartan 111 FPGA Development Board when selected. The following specifications must be met for the display of the variables: 1. The units of all variables are to be displayed along with the respective reading. 2. The voltage is to be displayed to 1 decimal point. 3. The current is to be displayed to 2 decimal points. 4. The temperature is to be displayed as a whole number. 5. The display of the readings for voltage, current and temperature are to automatically appear in a cyclic manner, with each reading being displayed for 5 seconds. 6. All leading zeros are to be suppressed. (ECNG 2004 Design Project Description) This design had both an analog and a digital component. ANALOG COMPONENT This component involved the design and construction of the Series Pass Voltage Regulator and the sensing circuitry to detect current, voltage and temperature. These sensors were constructed to relay the values necessary for the digital component. Analog to Digital Converters were designed to convert the analog output from the current, voltage and temperature sensing circuits to digital format so as to be to be read by the Spartan FPGA Board. Design of the Operational Amplifier Series Voltage Regulator Figure : Circuit Diagram of the Operational Amplifier Series Voltage Regulator The regulator was powered by a DC input voltage from a laboratory power supply. The voltage used in the design process for the purpose of calculation was 15 volts. Choosing the Zener Voltage and Zener Current The Zener Voltage, Vz was supplied by the Zener Diode, D1 as shown in Figure 7 above. The Zener Voltage was used as a reference voltage by the Operational Amplifier. The op amp is functioning as a differential amplifier in this situation. The difference between the inputs at the inverting and non-inverting terminals is amplified. Gain, The output voltage, VZ zener voltage Vz should be high enough so that gain would not decrease to achieve the required output. If Vz was too high, i.e. the output voltage, no current would flow through D1. An appropriate value between 0V and 9V was chosen, VZ = 4.8V. The IN4732 Zener Diode was chosen and the specification sheet for this model was obtained. The specified test current was 53mA, and the chosen value was 40mA. This was chosen to ensure proper bias. Calculating Resistor R3 The resistor R3 was in series with the Zener Diode. Therefore, the current through them is the same. A 100 à ¢Ã¢â‚¬Å¾Ã‚ ¦ resistor was chosen as it was the closest one in value available in stores. R3 = 100à ¢Ã¢â‚¬Å¾Ã‚ ¦ Calculating Resistors R1 and R2 Resistors R1 and R2 formed a potential divider providing the inverting input of the op amp. This sampled the output and sent it to the error amplifier. If the value of the output changed from the designed, the voltage drop across the resistors would change and the op amp input voltage would change, producing an error voltage at the output of the op amp. This error voltage will either turn on more or turn off more Transistor Tr1 and effectively Tr2 as well. The output voltage, Vo is related to the Zener Voltage by the equation below. Substituting Vo = 9V and Vz = 4.8V, Therefore, If R2 chosen to be 10kà ¢Ã¢â‚¬Å¾Ã‚ ¦, then Therefore, R1 = 8.8kà ¢Ã¢â‚¬Å¾Ã‚ ¦ and R2 = 10kà ¢Ã¢â‚¬Å¾Ã‚ ¦. Choosing an Operational Amplifier The LF351 op-amp was chosen for this design. It only needed to function as a differential amplifier. Choosing the Series Pass Transistor The required output current was 1 Ampere. Therefore the maximum collector current of the series pass transistor had to be greater than 1 A. high power transistor was needed, but the current gain of power amplifiers is low (approximately 40). The base current and collector current for a transistor are related by the following expression. Substituting Current gain, hfe = 40 and Ic = 1 A, The LF351 op amp could not supply this base current. A Darlington Pair arrangement was used instead. Darlington Pairs have high current gain. The high power transistor chosen was TIP31C, packaged in a TO-220 Case. The current gain, hfe1 of this transistor was specified to be between 10 and 50, so a value of 30 was used. An NPN medium power transistor, BFY51 in a TO-39 metal package, was chosen for Tr2 in Figure 6. The current gain, hfe2 was found to be 123. Hence, total current gain of the Darlington Pair: hfe1 ÃÆ'- hfe2, i.e. 30 ÃÆ'- 123 = 3690. Substituting Current gain, hfetotal = 3690 and Ic = 1 A, Design of the Voltage Sensing Circuit The purpose of the Voltage Sensing Circuit was to determine the output voltage of the regulator and relay this voltage to the Analog to Digital Converter input. The Analog to Digital Converter (ADC) chip (ADC08040 IC) had a reference voltage of 4.5V. The maximum voltage possible was 9.5V. Hence if the voltage output was 9.5V, the ADC08040 input voltage should be 4.5V. VO had to be stepped down by a potential divider before it could be sent to the ADC08040. It was stepped down by a factor of . Let R1 = 1kà ¢Ã¢â‚¬Å¾Ã‚ ¦, then R2 = 1kà ¢Ã¢â‚¬Å¾Ã‚ ¦ This voltage was sent to a Unity Gain Voltage Follower (Figure 8) and was input to the ADC circuit. (Prof. Gift, 2012) Voltage Sensor.bmp Figure : Voltage Sensing Circuit Design of the Current Protection Circuit The purpose of this was to disconnect the load from the regulator when the current flowing through the load surpassed 1A. The protection circuit monitored the load current and sent a signal to a device to disconnect the load, when the current rose to over 1A. A 1à ¢Ã¢â‚¬Å¾Ã‚ ¦ shunt was used in series with the 9à ¢Ã¢â‚¬Å¾Ã‚ ¦ load resistor. The shunt voltage was used to determine cut-off. An instrumentation amplifier was chosen (INA114AP) to compare the temperature sensor voltage and a potential divider voltage. The shunt voltage was amplified to increase chances of accurate determination of when to disconnect the load. A potential divider was constructed to deliver a4V, and the shunt voltage was also amplified to 4V. Potential Divider: Which gives: Let R1 = 20kà ¢Ã¢â‚¬Å¾Ã‚ ¦ The voltage from the shunt was amplified to 4V as well, and this was done by an op-amp and two resistors set up in the non-inverting amplification configuration shown below. The reference used to be amplified was 0.9V from the shunt, as this was the value which, if exceeded, cut-off and disconnection of the load was supposed to occur. For an non inverting amplifier, Vo = 4V, Vi = 0.4V, And Let R1 = 2.4kà ¢Ã¢â‚¬Å¾Ã‚ ¦, R2 = 8.2kà ¢Ã¢â‚¬Å¾Ã‚ ¦ .Temperature Amp Input to INA.bmp Figure : Circuit for Comparison and Determination of Cut-off When both inputs have the same voltage across them, the instrumentation amplifier would have an output of zero. The transistor in Figure 10 would be turned off and the base would be at 0V. The transistor used was a 2N3904 (Ic = 200mA). If the output is non-zero, the base would be driven by a voltage and the transistor will be ON. When the output is zero (same inputs) the transistor would be OFF and the relay coil would be grounded through the transistor. Current would flow through the coil, producing a magnetic field, and the relay would latch. When the instrumentation amp inputs are different, the output would saturate at +Vcc, i.e. 9V. The coil would an equal voltage at either end and so would have no voltage drop across it, meaning no current flowing through it. The relay is effectively OFF. There is a Normally Open (N.O.) Switch between pins 2 3, and 7 5 of the relay as well as Normally Closed (N.C.) Switches across pins 2 3 and 7 6. The N.O. switches close and the N.C. switches open when the relay latches. The load was connected across the N.C. pins. When the instrumentation amp has the same inputs, (zero output), and there is a voltage drop across the coil, current flows and the relay latches, disconnecting the load from the circuit. The relay had a rated voltage of 6V and the coil had a measured resistance of 70.5à ¢Ã¢â‚¬Å¾Ã‚ ¦. The relays, however, were actually found to latch at a voltage of 3.2V. Therefore for calculation purposes 3.5V is used = 49.6mA was needed to latch the relay. A potential divider was used to provide the required voltage for the relay. For a resistor R3, This caused a voltage drop across the coil, larger enough to activate the coil when necessary. The voltage across resistor R3 is given by, For Ic = 49.6mA, The Base Current of the transistor is given by For Ic = 49.6mA, and hfe = 100, To bias the base of the transistor for the 9V output of the op-amp, A 16kà ¢Ã¢â‚¬Å¾Ã‚ ¦ resistor was used. This would change VBE of the transistor. The new VBE was well within the operating range required for the resistor. Temperature Cutoff.bmp Figure : Current Protection Circuit Design of the Current Sensing Circuit The Current Sensing Circuit determined the voltage regulator output load. This value of current would be received by the ADC input. The ADC chip (ADC08040 IC ) was 4.5V. The Current LUT could convert a maximum of 1.29A. This means when the regulator reaches 1.29A, the ADC will be at 4.5V. A 1à ¢Ã¢â‚¬Å¾Ã‚ ¦ shunt resistor was placed in series with the load. The 9V regulated output would now be applied to a combined load of 10à ¢Ã¢â‚¬Å¾Ã‚ ¦. Voltage drop across the shunt: Therefore: The output voltage across the shunt is 0.9V. This will correspond with the maximum voltage which will give all 1s at the ADC output. Thus the voltage must be stepped up using a non-inverting op-amp. The voltage of 0.9V was stepped up to 4.5V. This means the gain is = 5 Let R1 = 2k à ¢Ã¢â‚¬Å¾Ã‚ ¦. Therefore, R2 = 8kà ¢Ã¢â‚¬Å¾Ã‚ ¦ The potential divider voltage was passed through the amplifier and then input into the ADC. Current Sensing Circuit.bmp Figure : Current Sensing Circuit Design of the Temperature Protection Circuit This disconnects the load from the regulator when the temperature of the Power Transistor (TIP31C) reached 40 °C. The Power Transistor temperature was monitored and at 40 °C, a signal would be sent from the circuit to a device, disconnecting the load. The LM35DZ was chosen. Its sensitivity was 10mV/ °C. At 40 °C, the temperature sensor output would be 0.4V. An instrumentation amplifier (INA114AP) was chosen to compare the temperature sensor voltage and the potential divider voltage. For a more accurate determination of the load, the temperature sensor output voltage was amplified. The potential divider delivered a voltage of 4V, and the sensor output voltage was also amplified to 4V. Therefore: Let R1 = 20kà ¢Ã¢â‚¬Å¾Ã‚ ¦ An op amp and two resistors were used to build a non-inverting amplifier in order to set the temperature sensor voltage to 4V. The reference voltage was 0.4V, since it is at this point cut-off should take place. For a non-inverting amplifier: , , Let R1=1kà ¢Ã¢â‚¬Å¾Ã‚ ¦ and R2=9kà ¢Ã¢â‚¬Å¾Ã‚ ¦, Temperature Amp Input to INA.bmp Figure : Amplifier Circuit for Comparison and Determination of Cut-off . When both input voltages are the same, the amplifier output would be 0V, turning off the transistor. (No VBE present). A 2N3904 transistor was used (Ic = 200mA), so the current would be large enough to latch the relay. If the amplifier output is not 0V, there would be a voltage drop across the base and the transistor would be ON. When the amplifier output is 0V, the transistor would be OFF, grounding the relay, causing current flow in the coil, latching the relay. When the amplifier inputs are at different levels, the output saturates at +Vcc = 9V. Equal voltages exist at both ends of the coil, so no current flows hence the relay is OFF. A Normally Open (N.O.) Switch exists across pins 2 3, and 7 5 of the relay. Normally Closed (N.C.) Switches exist across pins 2 3 and 7 6. The N.O. switches close and the N.C. switches open upon latching. Consider this load connected across the N.C pins and the amplifier has equal inputs. The amplifier output is 0V, causing a voltage drop across the relay coil, causing current flow and latching of the relay. It follows then that the load is disconnected from the circuit. For a resistor R3, R3 was used to activate the coil by creating a voltage drop across it. For Ic = 49.6mA, For biasing, A 16kà ¢Ã¢â‚¬Å¾Ã‚ ¦ resistor was used instead. Temperature Cutoff.bmp Figure : Temperature Protection Circuit This circuit was designed to relay the temperature of the power (TIP31C) to the ADC input. The ADC chip (ADC08040 IC ) reference voltage was 4.5V. The Temperature LUT could convert up to 129à ¢Ã‚ Ã‚ °C. At this temperature, the ADC should be 4.5V. A Temperature Sensor (LM35DZ) in a TO-92 package used to determine the temperature. This had a sensitivity of 10mV/ °C. At 129 °C, VO = 1.29V. Sensor output voltage was stepped up using a non-inverting op amp by a factor of , Let R1 = 1k à ¢Ã¢â‚¬Å¾Ã‚ ¦. R2 = 2.49kà ¢Ã¢â‚¬Å¾Ã‚ ¦ à ¢Ã¢â‚¬ °Ã‹â€  2.5kà ¢Ã¢â‚¬Å¾Ã‚ ¦ The sensor voltage was amplified and input into the ADC. Temperature Sensing Circuit.bmp Figure : Temperature Sensing Circuit A copper strip board was used to build the voltage regulator circuit since the solderless breadboard could only take up to 0.5A. Inputs: Voltage Supply of 15V Outputs: Voltage Sensing Output OV Ground Regulated 9V Output Temperature Sensing Voltage A voltage follower was used to buffer the output. The circuit was constructed as seen in figure 15: Figure : Complete Sensing and Cut-off Circuit DESIGN OF THE ANALOG TO DIGITAL CONVERSION CIRCUIT An 8 bit representation was used with reference to the 4.5V signal. The analog signal was converted to a digital signal from the 3 sensing circuits using the schematic shown below. Analog to digital conversion was done using the. A resistor pack was used to provide over current protection. This circuit was built and tested for each of the three sensing circuits. A combination of LEDs was used for the input of the analog voltage. AD Converter Circuit.bmp Figure : Schematic for ADC control configuration Op amps were used to buffer the inputs. The outputs were mapped onto the respective pins of the 40-pin IDE cable used to interface with the Spartan III Board. Figure : 40 Pin Expansion Connector (Spartan III Toolkit Datasheet) Data was transmitted using these pins to the ADC. DIGITAL COMPONENT The FPGA board was programmed so as to use the Seven Segment Display. Xilinx ISE 7.1i was used to design and construct the display for all the variables. Design of the Basic Display Unit Multiplexers, Frequency Dividers, a Look up Table Device and a Binary Coded Decimal to 7-Segment Converter were used to create the Display Unit. The 16-bit 31 Multiplexer Multiplexers may have more than one input but usually have one output. A combination of numbers is assigned to each input pin. Using these combinations, the respective input data is sent to the output pin. Therefore the bits that are chosen which input data set to display. In this design, two multiplexers were used, a 4-bit 41 and a 16-bit 31 multiplexer. 31 means 3 data inputs, 16- bit means each input is of 16 bit capacity. 16bit3to1muxschem.bmp Figure : Schematic Diagram of a 16-bit 3 to 1-line Multiplexer The 4-bit 41 Multiplexer The 4-bit 41 multiplexer can handle up to four combinations of inputs. To select which input is displayed, two bits are necessary. The output was a bus of width 4 bits. It split the 16 bit output into four sets of 4 bits. The 4-bit 41 multiplexer is shown in figure 19. 4bit4to1mux.bmp Figure : Schematic Diagram of a 4-bit 4 to 1-line Multiplexer Binary Coded Decimal (BCD) to 7-Segment Display Unit The BCD unit accepts four bits of data, e.g. D3D2D1D0, and determines which segments of the 7-segment display to turn on and off so as to represent the value of the input data. Figure 20 shows a 7-segment display. This type of display is common in electronic equipment e.g. calculators, microwaves, digital clocks. The Minimum Expressions for the BCD are: Seg_a = D3D2D1D0 + D2D1D0 + D3D2 + D3D1 Seg_b = D2D1D0 + D2D1D0 + D3D2 + D3D1 Seg_c = D2D1D0 + D3D2 + D3D1 Seg_d = D2D1D0 + D2D1D0 + D2D1D0 + D3D1 + D3D2 Seg_e = D0 + D2D1 + D3D1 Seg_f = D3D2 + D2D1 + D1D0 + D3D2D0 Seg_g = D3D2 + D3D1 + D2D1D0 + D3D2D1 For each expression, logic gate circuits were created. Each segment was then used to build the final BCD to 7-Segment Converter. The combinations of segments that would form the values were organised. The Look-Up-Table (LUT) This was used to determine which display unit anodes were to be turned on and off. There were four individual 7-segment displays. Each one had its own anode and as such could be controlled by choosing the anode of the respective display. lut.bmp Figure : Schematic Diagram of a Look-Up-Table (LUT) Modulo 4 Counter The Modulo 4 counter was used to perform automatic cycling of the anodes to be displayed. Only one anode was on at a time for each different combination. Moduloo4counter.bmp Figure : Schematic Diagram of a Modulo 4 Counter For multiplexed displays, the entire display is not lit up as the same time. The characters are made up of segments which, under certain conditions, become active. Each character is displayed one at a time. Switching of characters takes place so fast it appears that all the displays are on at the same time. The speed of switching is called the frequency divider (in this case 1kHz). This activates the modulo 4 counter which causes the LUT to choose one of four inputs to be chosen from the 4-bit 4 to 1 multiplexer to send to the 7 segment display. The Combined Display Unit Data Unit.bmp Figure :Schematic Diagram of the Display Unit Upgrade of the Display Unit to display the Decimal Point The LUT controls the switching of the anodes on the four 7 segment displays. Each 7 Segment Display has a decimal point that can be turned on or off if necessary. This was necessary in this project when displaying voltage and current. For a voltage, the decimal point is on the 3rd anode, a2. 0 9. 0 V For a current, the decimal point is on the 4th anode, a3. 0. 9 9 A This means that the point will only be on when S0 and S1 select to display voltage or current, and when the third or fourth anodes are on respectively. The Essential Prime Implicants were chosen from a truth table and the minimized expression was produced as follows: The Logic Gate circuit was constructed as shown below and implemented in Xilinx ISE 7.1i. A Macro was then created and connected appropriately in the Updated Display Unit Schematic. Decimal Point Upgrade.bmp Figure : Logic Gate Circuit for Decimal Point Upgrade Upgrade of the Display Unit to display the Units for each Variable The Display Unit was upgraded a second time in order to allow the units of each parameter to show Parameter Unit Symbol for Unit Voltage Volts V Current Amperes A Temperature Degrees Celsius à ¢Ã‚ Ã‚ °C Table : Parameters to be Displayed and their Respective Units The BCD Converter had to be updated to ensure when certain select bits were chosen, the segments would align to form the unit symbol on the first anode. Since there are four select inputs, D3D2D1D0 , there are 16 possible combinations of these bits forming different outputs. 0000 to 1001 in binary form represents 0 to 9 in decimal form. This means that there are combinations 1010 to 1111 to choose from to display a unit. 1101 was chosen for voltage, 1110 for current and 1111 for temperature. Figure : Common
