Oedipus Rex †a Christ Figure Essays - 1020 Words

Oedipus Rex – a Christ Figure Sophocles’ famous tragedy, Oedipus Rex, perhaps â€Å"the most important and influential drama ever written† (â€Å"Sophocles† 717), presents in the person of Oedipus the model of a good ruler, a humanely intelligent and vigorously active leader, a man who earlier saved his adopted city Thebes from disaster. Is Oedipus an alter Christus besides? The numerous parallels between the figure of the king Oedipus and the figure of Christ in the Scriptures prompts the reader to ask the above question. For example, in the opening lines of the drama, Oedipus greets the crowd of suppliants (including old men, boys and children) waiting at his palace doors with the words: â€Å"My children,†¦show more content†¦In Mark 2:24: the Jewish priests, representing the people, came to Jesus: â€Å"And the Pharisees said to him, ‘Look, why are they doing what is not lawful on the sabbath?’ In Mark 8:11: â€Å"The Pharisees came and began to argue with him, seeking from him a sign from heaven, to test him.† Mark 10:2: â€Å"And Pharisees came up and in order to test him asked, ‘Is it lawful for a man to divorce his wife?’ Pharisees played such an important role as the representatives of the Jewish people that they are mentioned more than 12 times in the gospel of Mark alone. In Oedipus Rex the people come to seek help from their king because they are afflicted: â€Å"Armed with his blazing torch the God of Plague /Hath swooped upon our city emptying /The house of Cadmus, and the murky realm /Of Pluto is full fed with groans and tears.† Likewise in the Scriptures the people come to Jesus because they are afflicted with various ills. In Luke 17:12: â€Å"And as he entered a village, he was met by ten lepers, who stood at a distance. . . .† Luke 7:22 mentions in summary form some of the people who have come to Jesus for help: â€Å"And he answered them, ‘Go and tell John what you have seen and heard: the blindShow MoreRelatedHow to Read Literature Like a Professor1408 Words   |  6 Pagesordinary and the monstrous. -Sex: Evil, lust, seduction, temptation, danger.

Intercultural Communication Issues

Question: Discuss about the Intercultural Communication Issues. Answer: Introduction Multicultural communication is key in international business. Developing skills for managing intercultural communications is necessary for companies going international such as Amys company(Varner 2000, p.50). To succeed in international business, entrepreneurs must design intercultural competences, and strategies such how to employ a diversified workforce(Beckers Bsat 2014, p.145). Equally, creating trustful relationship is also important in international business. Intercultural Communication Issues Expanding business into the Chinese market requires Amy to understand their verbal and nonverbal cues(Fall et al. 2013, p.413). Besides, the growth in technology and internet makes cross-cultural communications key for companies expanding internationally(FernndezSouto, Gestal Pesqueira 2015, p.235). Some of the key issues that will affects Amy expansion into include: Language barrier. Non-verbal differences. Power distance. High context vs. slow context culture. Language Barrier Amy will face language barrier challenges as she expands into Chinese market(Cotton 2015, par.4). She only understands English and a majority of people in China speak Chinese. To succeed in her first meeting, Amy should identify a bilingual interpreter. Once the company establishes itself in China, it should focus on employing individuals who are proficient in various languages(Pikhart 2014, p.952). Nonverbal Differences There is considerable distinction between individualist and collectivist cultures in terms of intercultural communication(Kutz 2013, p.66). Individuals from the above cultures use gestures and eye contact differently. It is important for Amy to address her nonverbal cues before her first meeting with Chinese business associates. She needs to understand that Chinese consider too much gestures as being rude. In Australia, prolonged eye contact is considered straightforwardness and honest, but in China it is considered as being rude (Maude 2011, p.43). High Culture vs. Low Context Culture This refers to how individuals thoughts, feelings, and upbringing affect the manner in which they conduct themselves in different cultures(Mattock 2003, p.54). Australia is a low culture context while China is a high context culture (Gudykunst 2003, p.45; Brink Costigan.2015, p.10). Businesses in Australia are individualistic, meaning the decisions are based on facts. Likewise, trust between business people is valued. High culture countries such as China value interpersonal relationship (Norales 2006, p.45). Continuation Business individuals from China emphasize on developing personal relationship before signing a contract. Additionally, they are concerned with group success rather than individual success(Norales 2006, p.45). Given these differences, it will be difficult for Amy to negotiate her business deal. For instance, Amy might focus on getting the deal done, and the foreign partner might not be happy with her actions. In essence, the foreign partner might consider Amy as someone who aims to fulfill her selfish interest. Summary and Conclusions Cultural diversity is essential for Amy to succeed in Chinese Market. Additionally, intercultural communication determines the success or failure of the company in any international market. For this reason, Amy needs to have detailed information regarding nonverbal and verbal distinctions between Australia and China. Ability to communicate effectively with individuals from distinct cultures is key in succeeding in international markets, to be precise China. Continuation For instance, effective use of verbal and nonverbal cues will eliminate incidents of miscommunication. China considers it a taboo to unintentionally offend someone using body language. In this case, Amy should always use open-handed gestures to communicate with her international partners. She should also shun from utilizing ok symbols, index finger, and thumbs up and down. Recommendations To succeed in the Chinese market, Amy should do the following: vMaintain an open mind in situations that are unfamiliar to her. vBe alert on how individuals form distinct cultures interact. vBe ready to adapt and learn in any new environment. vDemonstrate reliability and consistency.

The History of and Impact of Photography on our World Essay Example For Students

The History of and Impact of Photography on our World Essay Photography is a process frequently used in areas of media, art, and science as well as practical everyday use. It is used to inform society of different issues, used to document a wide range of things and is used to capture everyday memories for the years to come. It is used everywhere in todays society and through technology has advanced tremendously since its beginnings. The earliest cameras were simple devices that did not capture an image but merely projected an image onto a surface. It was basically a large pinhole camera in the form of a darkened room or booth. These were used by artists as early as the 16th century. These were known as Camera Obscuras. They then improved this method by replacing the pinhole with a telescope lens. By the 17th century they even made this system portable in the form of sedan chairs. In 1727 the first photo-sensitive compound was discovered completely by accident by Professor J. Schulze. The mixture consisted chalk, nitric acid, and silver in a flask; and the professor noticed that the side of the flask exposed to sunlight, darkened. (Tom Ang:2001)After that many significant events We will write a custom essay on The History of and Impact of Photography on our World specifically for you for only $16.38 $13.9/page Order now happened that resulted in the cameras we have today. These include Nicà Ã‚ ©phore Nià Ã‚ ©pce merging the Camera Obscura with photosensitive paper in 1816 and then creating a permanent image in 1826. This image was exposed for eight hours and the lens was facing the window of his estate in central France. In 1829 Niepce paired up with Louis Jacques Mandà Ã‚ © Daguerre to improve on the current techniques used. Daguerres most important discovery came two years after the death of his partner in 1835. He discovered silver iodine was more sensitive to the light and needed much less exposure time to create a fixed image. And then in 1837 he figured out a way stop the image darkening over time. He washed the remaining silver iodine away with a solution of salt and water. (Andy Grundberg:2005) From this photography developed and evolved over time and cameras became extremely convenient and easy to use. It has even branched out into the digital realm allowing endless possibilities to the world of photography. Photography revolutionized the world in ways we cant even imagine. Imagery is such an important part of our everyday lives and photography has created a convenient way to convey an image. Before photography came about the only way of having a permanent image of a person was to have a portrait painted. The only way of creating an image to show the scenery and landscape of a certain era was to have it painted or drawn. Nowadays we can take a snapshot and years later people can see the world as it was today. Photos have changed the world of journalism, creating a way for people to actually see what is going on, rather then just hearing about it. Today we use photography frequently in our everyday lives and we are constantly surrounded by images that would not have been possible without photography. Its considered a hobby for some, a business for others. Photography is a huge money making industry, from people taking pictures to sell to magazines to portrait photographers taking happy snaps of families at their best. Photography is used as a form of identification, showing us exactly how we are and proving we are who we say. It is used to sell products and advertise almost anything you can think of. Its also used as a journalistic tool, to send a message to the world and inform others. It can be used as a learning aid and document scientific processes. Finally photography preserves our memories and gives us something to hold onto. .u8d651f5c45624d96cf7ab6412337e435 , .u8d651f5c45624d96cf7ab6412337e435 .postImageUrl , .u8d651f5c45624d96cf7ab6412337e435 .centered-text-area { min-height: 80px; position: relative; } .u8d651f5c45624d96cf7ab6412337e435 , .u8d651f5c45624d96cf7ab6412337e435:hover , .u8d651f5c45624d96cf7ab6412337e435:visited , .u8d651f5c45624d96cf7ab6412337e435:active { border:0!important; } .u8d651f5c45624d96cf7ab6412337e435 .clearfix:after { content: ""; display: table; clear: both; } .u8d651f5c45624d96cf7ab6412337e435 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u8d651f5c45624d96cf7ab6412337e435:active , .u8d651f5c45624d96cf7ab6412337e435:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u8d651f5c45624d96cf7ab6412337e435 .centered-text-area { width: 100%; position: relative ; } .u8d651f5c45624d96cf7ab6412337e435 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u8d651f5c45624d96cf7ab6412337e435 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u8d651f5c45624d96cf7ab6412337e435 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u8d651f5c45624d96cf7ab6412337e435:hover .ctaButton { background-color: #34495E!important; } .u8d651f5c45624d96cf7ab6412337e435 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u8d651f5c45624d96cf7ab6412337e435 .u8d651f5c45624d96cf7ab6412337e435-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u8d651f5c45624d96cf7ab6412337e435:after { content: ""; display: block; clear: both; } READ: World literature assignment Essay ThesisSome people say the future of photography is entirely digital. The digital world is taking over almost every aspect of our lives, so why not photography? Digital cameras have become extremely affordable and easy to use. I think there will always be a place for traditional film photography in this digital world. When you consider that before we even had photography we had paintings. And although photography took off and expanded greatly as a genre of art we still have paintings and people willing to paint. However the digital camera is not something to be ignored. It has made life a lot easier for people. It has changed the speed at w hich an image can be processed and how the image is processed. Also the image can be further manipulated through computer programs such as Photoshop.

For this reason, the student will be forced to include the main point s only so that they get the full mark as compared to filling the paper with content that will instead lower their grade. When a student chooses a topic, they need to be sure that they will populate it to the latter. One of the tips of assisting the student to do so is writing down the main points. Here, the student writes down the key words that will guide them in elaborating the entire point. It reduces any probability of forgetting important sections of the PhD thesis. The student is at the advantage of finishing the paper in good time because they have somewhere to refer their main points and that research will be an easier task. Students should form a habit of researching from different sources to ensure that they get the opinions of different writers. The student should visit different writers to get some of the important tip of writing their thesis.

Why School Attendance Matters and Strategies to Improve It

Why School Attendance Matters and Strategies to Improve It School attendance matters. It is arguably one of the most important indicators of school success. You cannot learn what you are not there to learn. Students who attend school regularly improve their chances of being academically successful. There are obvious exceptions to both sides of the rule. There are a few students deemed academically successful who also have attendance issues and a few students who struggle academically who are always present. However, in most cases, strong attendance correlates with academic success, and poor attendance correlates with academic struggles. To understand the importance of attendance and the influence the lack thereof has, we must first define what constitutes both satisfactory and poor attendance.   Attendance Works, a non-profit dedicated to improving school attendance, has categorized school attendance into three distinct categories. Students who have 9 or fewer absences are satisfactory. Those with 10-17 absences are exhibiting warning signs for potential attendance issues.   Students with 18 or more absences have a clear cut chronic attendance issue. These numbers are based on the traditional 180-day school calendar. Teachers and administrators will agree that the students who need to be at school the most are the ones that are seemingly seldom there. Poor attendance creates significant learning gaps. Even if students complete the make-up work, they most likely will not learn and retain the information as well as if they had been there. Make-up work can pile up very quickly. When students return from an extended hiatus, they not only have to complete the make-up work, but they also have to contend with their regular classroom assignments. Students often make the decision to rush through or completely ignore the make-up work so that they can keep pace with their regular class studies.   Doing this naturally creates a learning gap and causes the student’s grades to drop. Over time, this learning gap increases to the point where it becomes nearly impossible to close. Chronic absenteeism will lead to frustration for the student. The more they miss, the more difficult it becomes to catch up. Eventually, the student gives up altogether putting them on a path towards being a high school dropout. Chronic absenteeism is a key indicator that a student will drop out. This makes it even more critical to find early intervention strategies to prevent attendance from ever becoming an issue. The amount of schooling missed can quickly add up. Students who enter school at kindergarten and miss an average of 10 days per year until they graduate high school will miss 140 days. According to the definition above, this student would not have an attendance problem. However, all together that student would miss nearly an entire year of school when you add everything together. Now compare that student with another student who has a chronic attendance issue and misses an average of 25 days a year. The student with a chronic attendance issue has 350 missed days or almost two entire years. It is no wonder that those who have attendance issues are almost always further behind academically than their peers who have satisfactory attendance. Strategies to Improve School Attendance Improving school attendance can prove to be a difficult endeavor.   Schools often have very little direct control in this area. Most of the responsibility falls on the student’s parents or guardians, especially the elementary aged ones.   Many parents simply do not understand how important attendance is. They do not realize how quickly missing even a day a week can add up. Furthermore, they do not understand the unspoken message that they are relaying to their children by allowing them to miss school regularly.   Finally, they do not understand that they are not only setting their children up to fail in school, but also in life. For these reasons, it is essential that elementary schools in particular focus on educating parents on the value of attendance.   Unfortunately, most schools operate under the assumption that all parents already understand how important attendance is, but that those whose children have a chronic attendance issue are simply ignoring it or do not value education. The truth is that most parents want what is best for their children, but have not learned or been taught what that is. Schools must invest a significant amount of their resources to educate their local community adequately on the importance of attendance. Regular attendance should play a part in the daily anthem of a school and a critical role in defining the culture of a school. The fact is that every school has an attendance policy. In most cases, that policy is only punitive in nature meaning that it simply provides parents with an ultimatum that essentially says â€Å"get your child to school or else.†Ã‚   Those policies, while effective for a few, will not deter many for whom it has become easier to skip school than it is to attend. For those, you have to show them and prove to them that attending school on a regular basis will help lead to a brighter future. Schools should be challenged to develop attendance policies and programs that are more preventive in nature than they are punitive. This begins with getting to the root of the attendance issues on an individualized level. School officials must be willing to sit down with parents and listen to their reasons for why their children are absent without being judgmental. This allows the school to form a partnership with the parent wherein they can develop an individualized plan for improving attendance, a support system for follow through, and a connection to outside resources if necessary. This approach will not be easy. It will take a lot of time and resources. However, it is an investment that we should be willing to make based on how important we know attendance to be.   Our goal should be to get every child to school so that the effective teachers we have in place can do their jobs. When that happens, the quality of our school systems will improve significantly.

Feudalism Assignment Example | Topics and Well Written Essays - 750 words

Feudalism - Assignment Example According to Nathan (2001 p. 3), it also had a highly trained military force (warriors) who were very expensive to maintain. On the other hand, the origin of feudalism can be linked with the expansion of the Roman Empire. It is believed that during the expansion, the Empire decentralized its reign and allocated land, power and authority to a group of people in exchange of military and slave services. Economic system According to Karl Marx, agriculture was the main pillar of economic development of feudalism. During the 12th century, most of the land was owned by dioceses, senior people and monasteries making the feudal system to be a way of ruling and communicating to the whole population. The land owners (landlords) gave out land as gifts to the less fortunate class people to cultivate. They peasants were supposed to cultivate it and give a certain amount of their harvest to the landlords in exchange of economic benefits, military services and of course public services. Just like the economic system, the social system of feudalism was hierarchical too. Every person had his or her own allegiance any person who was higher than him or her. The highest man was the King, followed by the lord (owner of the land also known as â€Å"Vassal† and â€Å"Caballero† in Spanish), Barons, knights and lastly the peasants. In order to maintain control, law, order and power, the medieval King was the one ranked highest who was above everything else and a warrior (Burn 1994 p. 234) The king owned a vast land which he gave out to any person who wanted to be part of his army as compensation; and that was the only way he could maintain a retinue of knights. Lands ownership laws were invoked again and again in order to reclaim property for the purpose recruitment of soldiers. Actually, the loyalty was basically a slavery type since the vassals knew they could not free themselves from his lord (Burn 1994 p. 251). The role of women: Feudalism did not consider women

Chinese Popular Culture - Essay Example This has lead to the turn of events among the citizens of the country whereby the workers have been laid off from their duties in various state owned companies. The presence of unemployment in the People’s Republic of China has led brought about the growth of personal challenges for unemployed workers and human resource policy challenges for the government. The unemployed population must find a way to cope up with the sudden change of their livelihood by searching for a similar means of making a living. In this paper, will focus on how college graduates deal with unemployment and how crime and corruption, along with social stability and mobility play a role in the PRC today. Furthermore, a detailed explanation of how unemployment creates serious problems with access to housing, education, and basic social services in the People’s Republic of China (Latham, 1-35). The employment situation in China for new college and university graduates seems to be unusual compared to t he present working group. The presence of the graduate unemployment crisis in China portrays the possibility of the wasteful investment of scarce resources. This is due to the factor that plenty of capital has been invested in educating unemployed graduates, which could or else have been invested in job-creating productive programs in the country. The presence of a large population of unemployed graduates makes the job market be very competitive. Furthermore, the graduates are also to be blamed in this issue because they always have negative expectations under the pressure of seeking jobs. According, to surveys done by various research houses in the People’s Republic of China most of the graduating students prefer to get an employment contract first, then they would later reflect on pursuing a new job position which is what they really desire to be employed for an average of two years. This assumption by the graduating students makes it possible for the emergency of the under employment and high turnover in the job market. In addition to this, the students will have lower levels of job satisfaction, job involvement, work commitment, and internal work motivation. Therefore, these issues will also bring the issue to the employers at the long run (Sato, 40-45). The People’s Republic of China seems to be experiencing the extreme increase of college graduates has outpaced the structural transition and rashly shifted the labor supply from semi-skilled manufacturing workers to more knowledge- intensive service professionals. This makes it the main reason for experts in the field and various scholars to emphasize that China requires extensive vocational training and industry engineering skills, which will help the country in solving its need for having manufacturing workers. Recently, a debate has emerged that economists say that the current situation of unemployment in China seems to portray that the country is running out of surplus labor. The presence of the unemployment population among the youth is a very complex social problem whereby it must be solved urgently. In the People’s Republic of China, the youthful population is termed to be highly educated because most of the youth are graduates. According to the nature of the economic status of the People’s Republic of China, the graduates are unwilling to choice factory work whereby they opt to compete for office-based positions. It is evident that graduates are four

Ariel Dorfmans Death and the Maiden 40 lines analysis Essay Example for Free

Ariel Dorfmans Death and the Maiden 40 lines analysis Essay The following forty lines from Ariel Dorfmans Death and the Maiden (1990), take place in scene 1 of Act 3, after Roberto has been tied up by Paulina and threatened with being tortured the same way as she had been, and then shot. In response to Paulinaà ¯Ã‚ ¿Ã‚ ½s threats, Roberto begins confessing the brutality of his actions and his motives. This confession may be true; however, Gerardo has advised Roberto to indulge Paulina, to confess as this would save his life. Whatever the case, the extract is important because it portrays how a man can slide into brutality, without initially meaning to. Second, the extract is important because it helps expose the iniquities of dictatorial military governments. Finally, it is also important because it gives us an idea of Robertos character and personality. In this extract we clearly see the stages by which a respectable doctor became a brutal sadistic torturer. Though Robertos brother told him that helping the torturers could be a way to pay the communists back for what they did to [his] dad, Roberto stresses that he accepted the job for humanitarian reasons. Firstly, he wanted to help the prisoners who were dying from the tortures as someone to help care for them, someone they could trust. Later on, however, Roberto became involved in more delicate operations and was asked to sit in on sessions where [his] role was to determine if the prisoners could take that much torture. This indicates that he was there while the prisoners were tortured, watching these brutal scenes. Roberto thought this was a way of saving peoples lives, as he ordered them to stop or the prisoner would die; however, watching brutalized him, and slowly the virtue [he] was feeling turned into excitement. Soon, brutalization took over [his] life and he began to truly like what [he] was doing, so much so that, from an observer, he became a participant. Torture became a game for him, a game that was partly morbid, partly scientific, as he tortured women to find out things like How much can this woman take? More than the other one? Hows her sex? Does her sex dry up when you put the current through her? Can she have an orgasm under those circumstances? By the end, Roberto had become a sadist totally obsessed with carry[ing] out all [his] fantasies of sexually torturing women who were entirely in his power, women with whom he could do whatever [he] want[ed]. So, stage by stage, we see in the example of Roberto how men can slide from positions of respectability and motives of kindness and compassion to becoming human monsters, men who delight in the sufferings of others. The tragedy of Robertoà ¯Ã‚ ¿Ã‚ ½s slide from being a humanitarian to being a torturer is emphasized by the style of his speech, which reveals that he is an intelligent, educated, insightful man. Firstly we see how Robertos diction indicates his intelligence and level of education. Words such as brutalization and morbid, and phrases such as he lost his capacity for speech, humanitarian reasons and install a totalitarian dictatorship clearly manifest his ability to speak articulately and in a high register. We also see how analytically capable Roberto is, as he does not just describe his own actions but explains why they occurred, carefully dissecting his his motives for working with the torturers, not to pay the communists back but for humanitarian reasons. He can organize his account in clear, logical stages, with phrases like It was slowly, almost without realizing how, At first, But afterwards, By the time, I began to, and It became. Additionally, even in the circumstances in which he is giving this confession, in fear of his life, Roberto uses figurative language, suggesting that he has good rhetorical abilities. He uses euphemism, for example, in calling torture sessions delicate operations, and he uses metaphors when he refers to his brutalization as the mask of virtue fell off, and to his descent into sadistic torture as the swamp. So, we see how Robertos use of language clearly reveals his high level of education and intelligence, and this makes us even more horrified at how such a sophisticated man could have become a brutal torturer of women. More than exposing the degeneration of individual men, exemplified in Roberto, however, this extract also exposes the iniquities of military dictatorships, like the Pinochet regime in Chile, which Dorfman himself had to flee from. We see how military governments divided families: though Roberto became a doctor devoted to saving lives, his brother, determined to pay the communists back for what they did to [their] father, took another path, joining the military dictatorship and becoming a member of the secret services.à ¯Ã‚ ¿Ã‚ ½ We also are given the impression of how military dictatorships can convince people to support them by manipulating their sufferings under previous governments, promising some kind of compensation, as Robertoà ¯Ã‚ ¿Ã‚ ½s brother joined the dictatorship to pay the communists back for what they didà ¯Ã‚ ¿Ã‚ ½ to his father à ¯Ã‚ ¿Ã‚ ½the day the peasants took over his land at Las Toltecas. Such governments also persuade people to support them, as Roberto did, by deceit and lies, getting Roberto involved in torture by saying the prisoners needed someone they could help care for them, but actually slowing criminalizing Roberto as a torturer. The fact that they have had such an enormous influence on Robertoà ¯Ã‚ ¿Ã‚ ½s personality shows just how psychologically manipulative such regimes can be. Finally, the fact that, throughout his speech, Roberto refers to the government only as they evokes the way in which such governments work in the shadows, secretly and anonymously, to torture and terrorize. Thus this extract does not only show how Roberto and men like him deteriorate when they become involved in torture; it also shows how dictatorial regimes can manipulate such men, facilitating and enabling this deterioration to occur. In conclusion, this extract is very important as, whether Robertoà ¯Ã‚ ¿Ã‚ ½s confession is true or feigned, it reveals how even the best of men may slide into such brutality and how military governments can create vile monsters out of exemplary human beings. Through the details of Robertoà ¯Ã‚ ¿Ã‚ ½s confession, Dorfman is inviting his audience to consider how a man becomes sub-human. If a respectable doctor, a benefactor to the community, could turn into such a monster because of the effects of such a regime, then what would happen to the rest of society? Dorfman tries to make the reader consider that this incident that has turned Robertos life into a monster might happen to anybody in our society; especially in a switch of regime.

Beethoven :: essays research papers

BEETHOVEN   Ã‚  Ã‚  Ã‚  Ã‚  Ludwig van Beethoven was born 1770 in Bonn Germany. His mother was a singer in the service; his father was a court musician that had little motivation and a drinking problem. His father noticed that Beethoven had a gift at a young age, and began teaching him piano and violin. But Beethoven was a hard learner, he was self-involved and impatient. This probably led to why he was a loner and why he only went to academic school for three years. Beethoven’s father wasn’t the only one who saw Beethoven’s talent, Gottlob Neefe (a German Organist) become young Beethoven’s mentor. Gottlob thought Beethoven was the next Mozart, so he sent him to Vienna to meet him. But Beethoven’s mother got sick so he had to come back home before he met him formally. By the time he came back to Vienna, Mozart had died so Beethoven sought help from Hadyn, another German composer. He became Beethoven’s second mentor and taught him new styles of music. Beethoven did his first shows in Vienna in 1795. He was the first composer that was not supported by wealthy persons; instead Beethoven supported himself with money from selling his music. By 1778, Beethoven started hearing humming and whistling sound in his ears, and it got worse. A few years later, he became completely deaf. Although he was deaf he could still write music. He finished his first symphony in 1800. In 1802, Beethoven became depressed and thought a lot about suicide. He went to a small village in Germany where he stayed for a few years. The next couple of years Beethoven created his most impressing masterpieces. In 1812 he had completed over twelve of his best works and he was known worldwide. But after this Beethoven did not release any music for awhile and he got in trouble with the law over some royalties to songs. But in 1817 he began composing again and he did through 1824. In 1824 Beethoven composed two of his most memorable pieces, the Ninth Symphony, and Ode to Joy, these were two of Beethoven’s best compositions. The first time Beethoven conducted the Ninth Symphony, the crowd, at the end of it was at a tremendous applause. And Beethoven was still with his back turned on the podium until one of the â€Å"soloists† turned him around. In 1820 Beethoven won custody of his nephew Karl since his brother had

Stefan’s Diaries: The Craving Chapter 11

The following morning, I clutched the soft linen sheets up to my neck, as I had when I was a child. With my eyes squeezed shut, I could almost pretend I was home again. That Damon and I were still human and having our usual brotherly quarrels. That our father was somewhere on the plantation, working. That Katherine was alive. No – wait. That we had never met Katherine. Or†¦ maybe I was in bed at Lexi's house, unsure about my new life, but accepted in this new home of fellow vampires. I slowly came fully awake, and my fantasies crumbled against reality. I was in the Sutherlands' house, still a captive of their generosity and my brother's threats, an uneager groom being run quickly into an unwanted wedding. The Sutherlands weren't terribly formal but nevertheless expected everyone to show up at breakfast. My dressing went perhaps slower than it might have normally, as I adjusted my sock garters until they were perfect, fiddled with my cuffs, and ran my hands through my hair. I didn't much like looking in mirrors in those days. I hated who I saw there. By the time I finally made it downstairs to breakfast, the entire family was well into their meal. Mrs. Sutherland greeted me with a warm maternal smile that tore at my insides. Though I felt genuinely fond toward her, she was compelled to accept me. â€Å"Good morning,† I mumbled, slinking into my place. â€Å"Is there any coffee?† â€Å"You seem a bit down today, m'boy,† Winfield said, tucking his watch into his breast pocket. â€Å"And a bit thin, may I add. You definitely need fattening up before the wedding – I think I'll take you to the club today. They do a wonderful lamb and pudding.† Lydia gave me an apologetic smile. With a shock I realized that a pretty rose-pink scarf encircled her neck, neatly covering the usual spot for a vampire bite. Damon had fed on her. I turned my head from the coffee that had been placed before me, my stomach churning. Unconsciously, I touched my neck where Katherine used to bite me, remembering the pain and pleasure all wound up together so sickly. Was it a message to me? To remind me of what would happen if I failed to marry Bridget? â€Å"Stefan! Don't go to the club until later! We have a full day today,† Bridget warned. â€Å"We absolutely must, must, must go visit Bram's family. They just love Damon – Brammy's been taking him to all of the latest places, like that bar that serves real English-style Pimm's Cups! I'll have to wear my new blue muslin. To their house, not to the bar, naturally. It isn't a suitable place for ladies. Fanny wanted blue muslin for her trousseau, but her engagement didn't work out, poor thing†¦.† The door to the kitchen opened, and Damon stepped through. â€Å"Good morning, all,† he crowed, bright-eyed and chipper. He looked rested and sated as he gave Lydia a flirty bow and me a nasty wink. My shoulders clenched. â€Å"What are you doing here, Damon?† I asked in as innocent a tone as I could muster. â€Å"You didn't hear?† He sat down at the table and unfolded his napkin with a flourish. â€Å"Winfield begged me to move in.† â€Å"Oh.† I pushed my chair back from the table, plastering a wobbly smile on my face to mask my anger. â€Å"Er, Damon, would you mind joining me in the foyer for a moment?† Damon grinned at me. â€Å"But I just sat down and I'm ever so hungry.† â€Å"It will take but a minute,† I said through clenched teeth. Lydia looked at me curiously, but after a beat, Damon scraped his chair back and followed me to the foyer. â€Å"Milady, I'll return shortly.† The second we were out of earshot, I turned to my brother. â€Å"You are unbelievable. You're moving in now?† â€Å"Why thank you,† Damon said with a facetious bow. â€Å"And yes. Were you not listening last night when I talked about all the amazing†¦ amenities the Sutherland abode has to offer?† The room began to spin around me as rage overtook me. My patience with Damon's game was over. â€Å"Why bother with all of†¦ this?† I demanded. â€Å"These shenanigans? If you're so powerful, why not just go into a bank and make them give you all of the gold in their vaults?† â€Å"I suppose I could, but where's the fun in that?† â€Å"The fun?† I echoed in disbelief. â€Å"You're doing this for fun?† Damon's eyes hardened. â€Å"Tracks, brother. You're not thinking ahead.† He frowned and brushed some imaginary lint off my jacket. â€Å"Yes, I could just steal the money and leave town. But we're going to be around forever. Or at least I am. And compulsion doesn't always take. In case you didn't notice, Margaret remains quite stubborn, and having her or Winfield, should he ever shake my Power, go around waving my picture and calling me a thief†¦ well, I can't have that. It's much easier – and more fun – just to inherit it.† I gazed at the door that separated us from the happily dining Sutherlands. â€Å"Inherit it? As in, upon death?† â€Å"What? Why, brother, what exactly are you implying?† he asked, pretending to be hurt. â€Å"You keep your half of the bargain, and I don't go on a killing spree. Remember? I gave you my word.† â€Å"No, Damon,† I said. â€Å"You said if I didn't marry Bridget you would start killing everyone in that room. You specifically did not say anything about what would happen after we were married.† â€Å"Good point,† Damon said, nodding. â€Å"I'd like to kill a few people in their circle. Starting with that sycophant Bram. I think he has a thing for my Lydia, you know,† he added with mock anger. â€Å"Damon,† I growled. His eyes narrowed. â€Å"You take care of your wife. I'll take care of mine.† I looked at my brother sharply. â€Å"So then you do plan to kill Winfield after he signs over his fortune?† â€Å"For that, you will just have to stick around and see.† â€Å"I won't let you hurt any of them,† I promised through a clenched jaw. â€Å"You can't stop me. Whatever I choose to do,† Damon hissed back. We glared at each other. My hands curled into fists. He shifted his stance, ready for a fight. At that moment Mrs. Sutherland poked her head into the foyer. â€Å"Boys? Everything okay out here?† â€Å"Yes, ma'am,† Damon answered graciously. â€Å"We were just acquainting ourselves.† He pointed the door to the kitchen and gave a slight bow. â€Å"After you, Stefan.† Reluctantly, I passed back into the kitchen, Damon close on my heels. â€Å"So tomorrow we pick out our suits,† Damon said. He was acting as though we were continuing a mundane discussion from the foyer, rather than just having ended an argument over the fates of everyone in the room. â€Å"Stefan, we should match! Why, Bridget, weren't you just saying last night how someone, I forget who, matched her sister at another wedding? Silk or something?† He knew. He was my brother and he knew precisely how to torment me. Eternally. â€Å"Yes, of course, Damon,† Bridget said with a gratified smile, turning to me. â€Å"Stefan, you have to hear this. I thought about matching me and Lydia, but I'm not sure the effect would be as dramatic, what with Lydia's figure†¦Ã¢â‚¬  I slowly sank down at the table, drowning in her words – and the knowledge that Damon was right. I had never been able to stop my brother, especially not when it mattered most.

Embedded system

AbstractionAn Embedded system has become indispensable in our lifes: autos, airplanes, powerplant control systems, telecommunications systems, all contain digital calculating systems with dedicated functionality. Most of them are real-time systems which response to their seasonableness restraints. The seasonableness demand has to run into under influence of unpredictable stochastic behaviour of the system. In this thesis we address stochastic undertaking executing times. In programming of undertakings in real-time systems, it is normally assumed that the undertakings consume their WCET in every supplication. This is a pessimistic premise that is made in order to vouch difficult real-time public presentation. However ; there exist real-time systems that have soft existent clip restraints. The benefit of loosen uping the premises is that more systems are schedulable and, more significantly, systems with a higher burden is schedulable.The end of the undertaking is to:* Implementing Stochastic WCET and the least slack foremost scheduling algorithm in a real-time system simulator. * Experiments should be performed in order to look into by experimentation the benefits in footings of figure of schedulable systems utilizing stochastic wcets compared to utilizing fixed wcets. The consequences show the public presentation and the advantage gained by least slack foremost scheduling algorithm which has lowest possible slack clip.Key wordsRTOS, Simulation, Tasks, Response clip, Worst instance response clip, worst instance executing clip.three Sammanfattningbegreppen Baddat in systemen har bli oumbarlig I var livsform: bil, flygmaskinerna powerplant kontroll systemen telecommuncations systemen, de all innehalla digital arbete med computing machine systemen med hangiven funktionellitet.

Most of them, if non all, are real-time systems, i.e. their responses to stimulations have timeliness restraints. The seasonableness demand has to be met despite some unpredictable, stochastic behaviour of the system.1.2 ObjectiveThe chief aim of this thesis is to develop 1.

Experiments should be performed in order to look into by experimentation the benefits in footings of figure of schedulable systems utilizing stochastic wcets compared to utilizing fixed wcets. 3.

Chapter 3, outlines the job preparation. Chapter 4, describes the solution. Chapter 5, demonstrates the rating of the simulation. Chapter 6, shows the related plants. Chapter 7, follows decisions from the consequences obtained.Chapter 2BackgroundThis chapter introduces basic constructs and notations needed for understanding the balance of the thesis. Section 2.1 presents the chief constructs of real-time and embedded systems. Section 2.2 presents the constructs of least slack first algorithm and their types.2.1 Real-time and Embedded Systems2.1.1 RTOSReal-time Operating System, an operating system designed to be used in existent clip systems. A Real clip systems has been defined as Any information processing activity or system which has to react to externally generated input stimulations within a finite and specified hold. The basic features of a real-time systems or embedded computing machine systems have been considered. They were: 1. Breadth and complexness 2. Manipulation of existent Numberss 3. Real-time control. 4. Efficient execution. 5. Extreme dependability and safety. Systems, in which the rightness of their operation is defined non merely in footings of functionality but besides in footings of seasonableness, organize the category of real-time systems. Hard Real clip systems: Seasonableness demands may be difficult significance that the misdemeanor of any such demand is non tolerated. In a difficult real-time system, if non all deadlines are guaranteed to be met, the system is said to be unschedulable. To understand, design, predict, and analyze safety critical applications such as works control and aircraft control, hence the community focused on difficult existent clip systems, where interrupting seasonableness demands are non tolerated. The analysis of such system gives a yes/no reply to the inquiry if the system fulfils the seasonableness demands. Hard existent clip analysis relies on constructing worst-case scenarios. Hard existent clip analysis can non afford but to presume that worst instance scenarios ever go on and to proviso for these instances. This attack is the lone one applicable for the category of safety critical embedded systems, even if really frequently leads to important under use of resources. Soft Real clip systems: Systems classified as soft real-time may on occasion interrupt a real-time demand provided that the service quality exceeds prescribed degrees. The nature of real-time embedded system is typically heterogenous along multiple dimensions. For illustration, an application may exhibit informations, control and protocol processing features. It may besides dwell of blocks exhibiting different classs of seasonableness demands, such as difficult and soft. In the instance of soft real-time systems nevertheless, the analysis provides fittingness estimations, such as steps of the grade to which a system is schedulable, instead than binary categorizations.2.1.2 SimulationSimulation is a method which can be used for analysis of response clip. When we are utilizing simulation, a elaborate theoretical account of the system is executed in imitating a system before it is implemented helps cut downing hazards of failure.2.1.3 UndertakingsA procedure in a existent clip system normally with some deadline and a period.2.1.4 Response clipThe clip in which system gives end product after taking input.2.1.5 Worst instance response clipThe maximal possible response clip of a undertaking.2.1.6 Worst instance executing clip ( WCET )The longest possible executing clip of the undertaking. Stochastic theoretical account uses in: It improves schedulability of undertakings compared to presuming their executing times are ever equal to their wcets. It uses good known Techniques of Deterministic Analysis, such as barricading in shared resources, undertaking precedence assignment.2.2 Least slack foremost Scheduling Algorithm:Least Slack Time programming is a Scheduling algorithm. It assigns precedence based on the slack clip of a procedure. It is besides known as Least Laxity First and most common usage is in embedded systems, particularly those with multiple processors.2.2.1 Slack clipThis programming algorithm first selects those procedures that have the smallest â€Å" loose clip † . Slack clip is defined as the temporal difference between the absolute deadline, the ready clip and the tally clip. More officially, the slack clip for a procedure is defined as: ( d – T ) – degree Celsius ‘ Where, vitamin D is the procedure deadline T is the existent clip since the rhythm start degree Celsius ‘ is the staying calculation clip. It ‘s Suitable in: LST programming is most utile in systems consisting chiefly nonperiodic undertakings, because no anterior premises are made on the events ‘ rate of happening. The chief failing of LST is that it does non look in front, and works merely on the current system province. Therefore, during a brief overload of system resources, LST can be sub-optimal and it will besides be suboptimal when used with uninterruptible procedures. It is optimum in: 1. Processor pre-emption is allowed. 2. No contention for resources. 3. Single processor. 4. Arbitrary release times. 5. Arbitrary deadlines.2.2.2 Related plants on LSTWhen an algorithm contains same least loose clip, it causes tonss of unneeded exchanging so bad public presentation will be at that place, so to curtail that we use least slack first to a great extent. LSF scheduling algorithm implemented by threshold ; a fresh Dynamic Fuzzy Threshold Based least Slack First ( DFTLSF ) scheduling algorithm is presented. DFTLSF algorithm uses the lingual set ( uncountable set ) to depict the period and the slack clip which contains unsure characters. The threshold coefficient gotten by fuzzy regulations assigns the threshold of the running undertaking dynamically. Any one who wants to preempt this undertaking must hold the smaller slack clip than the threshold. The consequences of the simulations show that, comparing to the traditional LSF Algorithm, the exchanging figure ( SN ) is much smaller2.2.2.1 DFTLSF Fuzzy Threshold:Two characters are considered to judge the precedence of a undertaking in DFTLSF: 1. Slack Time. 2. Threshold. The most of import of the undertaking to the system is, The little coefficient consequences in the little threshold which causes the difficult pre-emption by other undertakings. Once the undertaking gets the CPU, its slack clip reduces to its pre-emption threshold degree which is computed. It wo n't acquire back until the undertaking is done or the undertaking is preempted by another undertaking. The algorithm integrates the advantages of the pre-emption scheduling algorithm and the non-preemption 1. It consequences in a double precedence system that is good for the undertakings put to deathing successfully and cut downing the exchanging figure. The method makes the agenda and the pre-emption flexible and sensible harmonizing to the state of affairs the undertaking faces. When the threshold coefficient is 0, the algorithm is the method becomes the LSF while the threshold coefficient gets its biggest one which is 1.Scheduling scheme:In DFTLSF scheduling algorithm, the dynamic fuzzed threshold coefficient is proposed. It improves the schedulability by adding a fuzzed threshold coefficient. To look for the threshold coefficient, some fuzzy regulations are made ; the threshold coefficient is used for the running undertakings in the system. It is compared with other undertakings loose clip to make up one's mind which one to run foremost. It decreases the switching figure among undertakings when the slack clip of the undertakings is about the same. As a consequence, it avoids the walloping ( trading ) in the system and improves the schedulability. Another betterment is the critical value of loose clip. It is introduced into the system to guarantee the undertakings which are about finished ca n't be preempted by other undertakings.2.2.2.2 Least Laxity First Scheduling:This can be a coprocessor capable of implementing dynamic programming algorithms which are, until now seldom used because of their complex calculations at agenda clip. LLF is an optimum programming methodological analysis that allows sensing of clip restraint misdemeanors in front of making a tasks deadline, but has the disadvantage of demoing hapless runtime behaviour in some particular state of affairss ( â€Å"thrashing† ) The Least-Laxity-First algorithm ( LLF ) is a dynamic programming method, i.e. it makes the determination about which undertaking to put to death following at schedule clip. Another great advantage of the Least-Laxity-First algorithm is the fact that except schedulability proving no farther analysis, e.g. for delegating fixed precedences to the undertakings, has to be done at development clip. Furthermore, Least-Laxity-First shows hapless public presentation in state of affairss in which more than one undertaking have the smallest slack.2.2.2.3 Enhanced Least Laxity First Scheduling:This algorithm preserves all advantages of LLF while bettering the tally clip behaviour by cut downing the figure of context switches. Calculation clip of this device is instead a affair of clip declaration than of the figure of undertakings. This is of high importance as LLF in certain state of affairss causes a large figure of unneeded context switches that can dramatically increase operating system operating expense. ELLF algorithm represents a inactive programming coprocessor, i.e. the device determines the undertaking to be executed next merely after an external start signal. The purpose of this betterment is to guarantee that in a state of affairs when some undertakings would usually get down to thresh, they are executed consecutively without preempting each other. This can non be done by merely doing the whole system temporarily Non-preemptive. With such a non-preemptive LLF-algorithm, undertakings may lose their deadlines.Advantages of Enhanced Least-Laxity- First Scheduling:1. It responses the clip analysis of threshing undertakings. 2. Number of Context Switches.2.2.2.4 Modified Least Laxity First Scheduling:A Modified Least-Laxity-First ( MLLF ) scheduling algorithm is to work out the frequent context switches job of the LLF programming algorithm. The MLLF programming algorithm allows the laxness inversion where a undertaking with the least laxness may non be scheduled instantly. If the laxity-tie occurs, MLLF scheduling algorithm allows the running undertaking to run with no pre-emption every bit far as the deadlines of other undertakings are non missed. Laxity Inversion Duration at clip T is the continuance that the current running undertaking can go on running with no loss in schedulability even if there exist a undertaking ( or undertakings ) whose laxness is smaller than the current running undertaking. Hence, MLLF scheduling algorithm avoids the debasement of systems public presentation.Chapter 3Problem FormulationSince the application sphere of this thesis is embedded systems, this chapter starts in subdivision 3.1 with a treatment on the bing programming algorithms based on Real clip systems. Section 3.2 presents the demand of Least Slack First Scheduling Algorithm in stochastic wcet.3.1 Scheduling Algorithms in Real-time SystemsFor a given set of occupations, the general programming jobs asks for an order harmonizing to which the occupations are to be executed by fulfilling with assorted restraints. Typically, a occupation is characterised by its executing clip, ready clip, deadline, and resource demands. The executing of a occupation may or may non be interrupted over a set of occupations and there is a precedency relation which constraints the order of the executing, particularly with the executing of a occupation can non get down until the executing of all its predecessors is completed.Types of Real-Time SchedulingFor illustration the systems on which the occupations are to be executed is characterised by the sum of resources available [ 22, 59, 30, 32, 27, 12 ] . The undermentioned ends should be considered in scheduling a real-time system: [ 30, 32, 27 ] . * Meeting the timing restraints of the system * Preventing coincident entree to shred resources and devices. * Achieving a high grade of use while fulfilling the timing restraints of the system. * Reducing the cost of context switches caused by pre-emption. * Reducing the communicating cost in real-time distributed systems. In add-on, the undermentioned points are desired in advanced real-time systems: * Sing a combination of difficult, and soft existent clip system activities, which implies the possibility of using dynamic programming policies that respect to the optimality standards. * Task programming of using dynamic programming policies that respect the optimality standards. * Covering dependability, security, and safety. Basically, the programming job is to find a agenda for the executing of the occupations so that they are all completed before the overall deadline [ 22, 59, 30, 32, 27, 12 ] . Given a real-time system, the appropriate programming attack should be designed based on the belongingss of the system and the undertakings happening in it. These belongingss are as follows [ 22, 59, 30, 32 ] : _ Soft/Hard/Firm real-time undertakings The real-time undertakings are classified as difficult, soft and steadfast real-time undertakings. Periodic/Aperiodic/Sporadic undertakings Periodic undertakings are real-time undertakings which are activated ( released ) on a regular basis at fixed rates ( periods ) . Normally, periodic undertakings have a restraint which indicates that cases of them must put to death one time per period. Aperiodic undertakings are real-time undertakings which are activated irregularly at some unknown and perchance boundless rate. The clip restraint is normally a deadline. Sporadic undertakings are real-time undertakings which are activated irregularly with some known bounded rate. The delimited rate is characterized by a minimal inter-arrival period, that is, a minimal interval of clip between two consecutive activations. The clip restraint is normally a deadline. An nonperiodic undertaking has a deadline by which it must get down or complete, or it may hold a restraint on both start and finish times. In the instance of a periodic undertaking, a period means one time per period or precisely units apart. A bulk of centripetal processing is periodic in nature. For illustration, a radio detection and ranging that tracks flights produces informations at a fixed rate [ 32, 29, 27, 12 ] . _ Preemptive/Non-preemptive undertakings In some real-time programming algorithms, a undertaking can be preempted if another undertaking of higher precedence becomes ready. In contrast, the executing of a non-preemptive undertaking should be completed without break, once it is started [ 32, 30, 27, 12 ] ._ Multiprocessor/Single processor systems The figure of the available processors is one of the chief factors in make up one's minding how to Agenda a real-time system. In multiprocessor real-time systems, the scheduling algorithms should forestall coincident entree to shared resources and devices. Additionally, the best scheme to cut down the communicating cost should be provided [ 32, 27 ] . Fixed/Dynamic precedence undertakings In precedence driven programming, a precedence is assigned to each undertaking. Delegating the precedences can be done statically or dynamically while the system is running [ 22, 59, 30, 32, 12 ] . _Flexible/Static systems For scheduling a real-time system, we need to hold adequate information, such as deadline, minimal hold, maximal hold, run-time, and worst instance executing clip of each undertaking. A bulk of systems assume that much of this information is available a priori and, hence, are based on inactive design. However, some of the real-time systems are designed to be dynamic and flexible [ 22, 59, 30, 32, 12 ] . _ Independent/Dependent undertakings Given a real-time system, a undertaking that is traveling to get down executing may necessitate to have the information provided by another undertaking of the system. Therefore, executing of a undertaking should be started after completing the executing of the other undertaking. This is the construct of dependence.3.2 Implementing Least Slack First in stochastic behaviour:The laxness of a procedure is defined as the deadline subtraction staying calculation clip. In other words, the laxness of a occupation is the maximum sum of clip that the occupation can wait and still run into its deadline. The algorithm gives the highest precedence to the active occupation with the smallest laxness. Then the occupation with the highest precedence is executed. While a procedure is put to deathing, it can be preempted by another whose laxness has decreased to below that of the running procedure. A job arises with this strategy when two procedures have similar laxnesss. One procedure will run for a short piece and so acquire preempted by the other and frailty versa. Thus, many context switches occur in the life-time of the procedures. The least laxness foremost algorithm is an optimum programming algorithm for systems with periodic real-time undertakings. If each clip a new ready undertaking arrives ; it is inserted into a waiting line of ready undertakings, sorted by their laxnesss. In this instance, the worst instance clip complexness of the LLF algorithm is where the entire figure of the petitions in each hyper-period of periodic undertakings in the system and is the figure of nonperiodic undertakings. vitamin E The executing clip of a undertaking depends on application dependant, platform dependant, and environment dependent factors. The sum of input informations to be processed in each undertaking instantiation every bit good as its type ( pattern, constellation ) are application dependent factors. The type of treating unit that executes a undertaking is a platform dependent factor act uponing the undertaking executing clip. If the clip needed for communicating with the environment is to be considered as a portion of the executing clip, so web burden is an illustration of an environmental factor act uponing the undertaking executing clip.Execution clip chance denseness mapshows the executing clip probability denseness of such a undertaking. An attack based on a worst instance executing clip theoretical account would implement the undertaking on an expensive system which guarantees the imposed deadline for the worst instance state of affairs. This state of affairs nevertheless will happen w ith a really little chance. If the nature of the system is such that a certain per centum of deadline girls is low-cost, a cheaper system, which still fulfills the imposed quality of service, can be designed. For illustration, such a cheaper a system would be one that would vouch the deadlines if the executing clip of the undertaking did non transcend a clip minute t. It can be seen from the, that there is a low chance that the undertaking executing clip exceeds Ts and hence, losing a deadline is a rare event taking to an acceptable service quality.Chapter 4Design and ExecutionThis chapter presents the design and execution of stochastic wcet and LSF scheduling algorithm in subdivision 4.1 severally.4.1 Design of Least Slack First Algorithm:Difficult real-time programming can be thought of as an issue for embedded systems where the sum of clip to finish each explosion is capable to these parametric quantities: Sum of work ( W ) , sum of slack clip ( S ) Assume that the Numberss are specified in footings of processor ticks ( timer interrupts ) . The deadline ( D ) is the amount of W + S, i.e. , slack clip exactly represents the sum of clip which in which the procedure can be preempted while finishing its explosion in order to accomplish the deadline. When a figure of procedures are trying to accomplish their deadlines the undermentioned calculation takes topographic point at each tick ( 1 ) : — W ; // for the current running procedure — Second ; // for all procedures on the ready waiting line Namely, the running procedure has completed another tick of work towards its deadline and the others have one less tick of slack clip available. In scheduling algorithms we imagine for such a system would non be time-sharing, but would be priority-based, where the precedence is measured by some sense of urgency towards finishing the deadlines. Least Slack First ( LSF ) : when a procedure completes a explosion or a new one becomes ready, schedule the procedure whose value S is the smallest. Or, it can concentrate on completing of the overall deadline. Both represent sensible impressions of fulfilling procedure urgency. Here is a simple illustration which illustrates the differing behaviour: Process idle clip explosion — — — – — — — — – — — – A 0 ( W=10, S=8 ) B 3 ( W=3, S=11 ) C 5 ( W=3, S=6 ) Using the LSF algorithm, we would finish these explosions as follows: Time run ready — — — – — — – 0 A ( 10,8 ) ( ) 3 A ( 7,8 ) ( B ( 3,11 ) ) 5 C ( 3,6 ) ( A ( 5,8 ) , B ( 3,9 ) ) 8 A ( 5,5 ) ( B ( 3,6 ) ) 13 B ( 3,1 ) ( ) 16 — – Based on the above illustration the codification has been generated and account for the above illustration: Iteration 1: At clip 0 A will be ( 10, 8 ) Where as 10 is W ( current running procedure ) , 8 is S ( ready waiting line ) . Iteration 2: At clip 3 We have 2 phases: 1. Run phase: At this phase the procedure A will ( 7, 8 ) because For 7: W – idle clip 8: ready waiting line 2. Ready phase: At this phase the procedure B will ( 3, 11 ) because For 3: idle clip 11: ready waiting line Iteration 3: At clip 5 Same as like Iteration 2 here besides we have 2 phases 1. Run phase: At this phase the procedure C will ( 3, 6 ) because For 3: idle clip 6: ready waiting line 2. Ready phase: Procedure A will be ( 5, 8 ) and B will be ( 3, 9 ) For 5: 10-5 i.e. W – idle clip 8: ready waiting line For B: 3: idle clip 9: W+S+idletime – idle clip – idle clip Iteration 4: At clip 8 In Run phase A will be ( 5, 5 ) Because one rhythm is executed so A ready waiting line will be minimized by 3 In Run phase B will be ( 3, 6 ) 6: W-idle clip -idle clip There will be a context switches. Iteration 5: At clip 13 In tally phase B ( 3, 1 ) 1: ready waiting line of loop 3 -idle clip.4.1.1Comparing of Slack undertakings:To compare loose undertakings in LSF with different conditions the codification has been written. if ( slackLeftT1 & lt ; slackLeftT2 ) { return -1 ; } if ( slackLeftT2==slackLeftT1 ) { return 0 ; } if ( slackLeftT2 & lt ; slackLeftT1 ) { return 1 ; } return 0 ; } }4.1.2Implementation of Execution times:In an existent executing clip, the executing block consumes a â€Å" guessed † executing clip that the scheduler is utilizing in its programming determinations. In the map executing, the category Computation demand to utilize the existent executing. In the LSF comparator we must do certain the â€Å" guessed † executing clip is being used. Lashkar-e-taibas denote the existent executing clip as C_to_be_executed_time and it is a data member of the category Computation. this.C_to_be_executed_time = distr.sample ( ) ; // clip that will be consumed by the executing block Let ‘s denote the â€Å" guessed † executing clip as C and it is besides a data member of the category Computation. this.C = distr.sample ( ) ; // Assumed WCET to be used by LSF scheduler We must now guarantee that the execute method consumes C_to_be_executed_time clip units and the LSF comparator uses C. Further, guaranting the executing times that are assigned in the builder of Computation category prevarication in the scope of 0 and some positive upper edge.4.1.3Implementation for scheduling periodic undertakings and work load:The below codification reference to implements the periodic undertakings. Periodic p1 = new Periodic ( 0,31, 0, â€Å" T1 † ) ; p1.installConditionedComputation ( new Computation ( new Normal ( 10,5 ) , p1 ) ) ; The work load can be calculated by, Workload = max executing time/ period clip.Chapter 5Evaluation of SimulationThis chapter describes the public presentation rating of the simulator. Section 5.1 presents the simulator foundation, while in subdivision 5.25.1 Eclipse and the Eclipse FoundationEclipse is an unfastened beginning community ; undertakings are focused on constructing an unfastened development platform comprised of extensile models, tools and runtimes for edifice, deploying and pull offing package across the lifecycle. The Eclipse Foundation is a not-for-profit, member supported corporation that hosts the Eclipse undertakings and helps cultivate both an unfastened beginning community and an ecosystem of complementary merchandises and services. The Eclipse Project was originally created by IBM in November 2001 and supported by a pool of package sellers. The Eclipse Foundation was created in January 2004 as an independent not-for-profit corporation to move as the steward of the Eclipse community. The independent not-for-profit corporation was created to let a seller impersonal and unfastened, crystalline community to be established around Eclipse. Today, the Eclipse community consists of persons and organisations from a cross subdivision of the package industry. In general, the Eclipse Foundation provides four services to the Eclipse community: 1 ) IT Infrastructure. 2 ) IP Management. 3 ) Development Process and, 4 ) Ecosystem Development. Full-time staffs are associated with each of these countries and work with the greater Eclipse community to help in run intoing the demands of the stakeholders. Eclipse – an unfastened development platform Eclipse is an unfastened beginning community ; undertakings are focused on constructing an unfastened development platform comprised of extensile models, tools and runtimes for edifice, deploying and pull offing package across the lifecycle. A big and vivacious ecosystem of major engineering sellers, advanced start-ups, universities, research establishments and persons extend, complement and back up the Eclipse platform. Used for 1. Enterprise Development. 2. Mobile + Device development. 3. Application model, linguistic communication ide. Eclipse Undertakings Eclipse is a aggregation of unfastened beginning undertakings built on the Equinox OSGi run-time. Eclipse started as a Java IDE, but has since grown to be much, much more. Eclipse undertakings now cover inactive and dynamic linguistic communications ; thick-client, thin-client, and server-side models ; patterning and concern coverage ; embedded and nomadic systems.5.2 simulator apparatus:On a high degree, the simulator simulates a computing machine system by utilizing objects that encapsulate different functionality and make up one's mind on parametric quantities on the objects. The undermentioned categories are of import: 1.ComputerSystem: c.add ( central processing unit ) ; 2.CPU: A CPU that is bound to the computing machine system DataDependencyGraph g = new DataDependencyGraph ( ) ;g.insertData ( 1, 0, 0 ) ;g.insertData ( 2, 0, 0 ) ;g.insertData ( 3, 0, 0 ) ;A information dependence graph that describes informations points in the system and their relationship. Think of the relationships a borders between nodes in a directed acyclic graph. Constructs a information dependence graph of three informations points. These informations points have no relationships. 3. ConditionedExecution: At least one learned executing that is bound to a undertaking. Periodic p1 = new Periodic ( 0, 100, 0, â€Å" T1 † ) ;p1.installConditionedComputation ( new IfTime ( 1, 10, 1, p1, g ) ) ;p1.installConditionedComputation ( new Computation ( 10, p1 ) ) ; Periodic p2 = new Periodic ( 0, 200, 0, â€Å" T2 † ) ;p2.installConditionedComputation ( new IfTime ( 1, 10, 1, p2, g ) ) ;p2.installConditionedComputation ( new Computation ( 10, p2 ) ) ; Periodic p3 = new Periodic ( 0, 103, 0, â€Å" T3 † ) ;p3.installConditionedComputation ( new IfTime ( 2, 10, 1, p3, g ) ) ;p3.installConditionedComputation ( new Computation ( 10, p3 ) ) ;Concepts three periodic undertakings. Each undertaking has two conditioned executings that execute in the order they are bound to the undertaking. 4.Tasks: At least one undertaking that is bound to a CPU. Vector & lt ; CPU & gt ; c = new Vector & lt ; CPU & gt ; ( ) ;CPU central processing unit = new CPU ( new WinOverSlack ( ) ) ;cpu.installTask ( p1 ) ;cpu.installTask ( p2 ) ;cpu.installTask ( p3 ) ;Instantiates a CPU and bounds the undertakings to the CPU. 5.Events: At least one information point that may be used by an executing ComputerSystem cs = new ComputerSystem ( degree Celsius, hint ) ;cs.eventLoop ( 10000 ) ;Concepts a computing machine system and bounds the array of CPUs to it. The method eventLoop starts the simulation and the simulation coatings when it reaches clip point 10000. 6.Trace: Trace hint = new Trace ( new OutputStreamWriter ( System.out ) ) ;Instantiates a hint where the end product of the simulation will be written. This hint writes to standard end product, which makes the end product to look in the console in Eclipse. In simulation, I used stochastic executing times on a sort of learned executing that is bound to a undertaking. This means that every clip the learned executingexecutes it consumes different sums of clip. Therefore, when an case of a undertaking starts we can take a conjecture how much clip it will devour. The system uses LSF that use the guessed executing clip.End product:Chapter 6This chapter focuses on alternate attacks and related research works viz. stochastic undertaking executing times. Hence, in the below subdivision we discussed related plants on stochastic worst instance executing times.Related plantsSome of the related work in stochastic undertaking executing times: Burns et Al. : [ BPSW99 ] addresses the job of a system by interrupting its seasonableness demands due to transeunt mistakes. In this instance, the executing clip variableness stems from undertaking re-executions and the shortest interval between two mistake happening such that no undertaking exceeds its deadline and is determined by sensitiveness analysis. The chance that the system exceeds its deadline is given by the chance that faults occurs at a faster rate than the tolerated one. Broster et Al. : [ BBRN02 ] Determines the response clip of a undertaking ; it re-executes K  º N times due to mistakes in order to obtain the chance distribution of the response clip, and it compute the chance of the event that K mistakes occur. The mistake happening procedure is assumed to be a poisson procedure in both of the cited plants. But Burns et Al. : Extend broster ‘s attack by adding statistical dependences among executing times. His attack are applicable to systems with sporadic undertakings, which are unsuited for the finding of undertaking deadline miss chances of undertakings with generalised executing clip chance distributions, and besides confined to sets which are independent undertakings implemented by utilizing monoprocessor systems. Bernat et Al. : [ BCP02 ] Address different job which determines the frequence with which a individual undertaking executes for a peculiar sum of clip, called executing clip profile and this was performed by based on the executing clip profiles of the basic blocks of the undertaking. The strength of this attack is that they consider statistical dependences among the executing clip profiles of the basic blocks. But nevertheless, this attack would be hard to widen to the deadline miss ratio analysis of multi-task systems because of the complex interleaving with the features of undertaking executings in such environments. Atlas and Bestavros: [ AB98 ] extends the classical rate monotone programming policy with an entree accountant in order to manage undertakings with stochastic executing times. It analyses the quality of the service of the ensuing agenda and its dependance on the entree control parametric quantities. The attack is limited to monoprocessor systems, rate monotone analysis and assumes the presence of an admittance accountant at run-time. Abeni and Buttazzo ‘s [ AB99 ] work addresses both programming and public presentation analysis of undertakings with stochastic parametric quantities. It focuses on how to schedule both difficult and soft real-time undertakings on the same processor, in such a manner that the difficult 1s are non disturbed by ill-behaved soft undertakings. Tia et Al. [ TDS95 ] presume a undertaking theoretical account composed of independent undertakings. There are two methods for public presentation analysis they were, one of them is merely an estimation and is demonstrated to be excessively optimistic. In the 2nd method, a soft undertaking is transformed into a deterministic undertaking and a sporadic 1. The sporadic undertakings are handled by a waiter policy. The analysis is carried out on this peculiar theoretical account. Gardner et Al, [ GAR99, GL99 ] in their stochastic clip demand analysis, present worst-case scenarios with regard to task release times in order to calculate a lower edge for the chance that occupation meets its deadline. It does n't incorporate informations dependences among undertakings and applications implemented on multiprocessors. Zhou et Al. and Hu et Al. [ ZHS99, HZS01 ] root their work in Tia's. , they do non mean to give per-task warrants, but characterize the fittingness of the full undertaking set. Because they consider all possible combinations of executing times of all petitions up to a clip minute, the analysis can be applied merely to little undertaking sets due to complexness grounds. De Verciana et Al. [ BPSW99 ] address a different type of job. Having a undertaking graph and an imposed deadline, its end is to find the way that has the highest chance to go against the deadline. In this instance, the job is reduced to a non-linear optimisation job by utilizing an estimate of the whirl of the chance densenesss. Diaz et Al. [ DJG00 ] derives the expected deadline miss ratio from the chance distribution map of the response clip of a undertaking. The response clip is computed based on the system-level backlog at the beginning of each hyper period, i.e. the residuary executing times of the occupations at those clip minutes. The stochastic procedure of the system-level backlog is Morkovian and its stationary solution can be computed. It contains sets of independent undertakings and the undertaking executing times may presume values merely over distinct sets. In this attack, complexness is mastered by paring the passage chance matrix of the implicit in Markov concatenation or by deploying iterative methods, both at the disbursal of consequence truth. Kalavade and Moghe [ KM98 ] see undertaking graphs where the undertaking executing times are randomly distributed over distinct sets. Their analysis is based on Markovian stochastic procedures excessively. Each province in the procedure is characterized by the executed clip and lead-time. The analysis is performed by work outing a system of additive equations. Because the executing clip is allowed to take merely a finite ( most probably little ) figure of values, such a set of equations is little. Kim and shin [ KS96 ] see applications that are implemented on multiprocessors and modeled them as line uping webs. It restricts the undertaking executing times to exponentially distributed 1s, which reduces the complexness of the analysis. The undertakings were considered to be scheduled harmonizing to a peculiar policy, viz. first-come-first-served ( FCFS ) .Chapter 7Conclusion & A ; Future worksThis chapter gives decisions in subdivision 7.1 and discusses issues for the future work in subdivision 7.27.1 DrumheadNow a yearss, systems controlled by embedded computing machines become indispensable in our lives and can be found in batch of application. And the country of embedded real-time systems introduces the facets of stochastic behavior of real-time systems. In my thesis I deal with platform specific stochastic undertaking. Because of rapid growing in embedded systems by twenty-four hours to twenty-four hours, the undertakings in a system are incomplexed mode in a existent clip system and it is normally assumed that the undertaking consume wcet in every supplication. And it is pessimistic premise that is made in order to vouch difficult real-time public presentation. But we have besides soft real-time restraints so that pessimistic premise could be relaxed. In my thesis I worked on loosen uping the pessimistic premise so that more systems are schedulable and more over it is really of import for a system to work on a higher work burden where it is to be schedulable. By this I can do this system to lose their deadlines.7.2 Future workBased on my thesis work, In certain countries it can be better farther by implementing Modified Least Laxity Scheduling Algorithm. By, the aid of this algorithm we can understate the context switches. By understating it, we can non happen any deadline girls and there will be hundred percent use of system which contains higher work burden.Chapter 8Mentions[ 1 ] hypertext transfer protocol: //www.cs.wcupa.edu/~rkline/OS/Scheduling-examples.html, Last updated: Oct 17, 2007.

The timing diagram of undertaking t1 before scheduling The timing diagram of undertaking t2 before scheduling The timing diagram of undertaking t3 before scheduling Sing a system dwelling of three undertakings and that have the repeat periods, calculation times, first supplication times and deadlines are defined in above tabular array. The undertakings are pre-emptive.Earliest Deadline First AlgorithmAs presented in below, the uniprocessor real-time system dwelling of the undertakings Set defined in Table 3 is non EDF-schedulable, because while the executing of the first supplication of the undertaking t2 is non finished yet ; the new supplication of the undertaking arrives. In other words, an overrun status happens. _ ?Rate Monotonic AlgorithmAs shown in below, the uniprocessor real-time system dwelling of the undertakings set defined in above tabular array is non RM-schedulable. The ground is that the deadline of the first supplication of the undertaking t3 is missed. The executing of the first supplication is required to be finished by clip 6, but the agenda could non do it.Least Laxity First AlgorithmBelow nowadayss a part of the timing diagram of the agenda provided by the least laxness foremost algorithm on the undertakings set defined in above tabular array. As shown in the, the deadline of the 3rd supplication of the undertaking t1 can non be met. we conclude that the uniprocessor real-time system dwelling of the undertakings set defined in tabular array is non LLFschedulable.
