Roles and Communication Between Groups as See in 12 Angry...

While watching the movie, 12 Angry Men, I saw many of the different things we have been discussing in class. The jurors all took different roles throughout the movie. These different roles contributed to the communication the group had, the stages of development, and how they came up with a consensus. The first juror was the foreman. He was the task leader of the group, taking initiative to sit the people down, numbering them, and telling the jurors when they could go on breaks. This juror goes over the process and rules the men will be using, and sets up the first voting. He also tries to keep the jurors on task and organized. Juror 2 is anxious man. This juror was easily persuaded to change his opinion about the case and tended to have the same opinion of the person who spoke before him. He played the role of a tension releaser which was seen when he offered the men cough drops in tense situations. Juror 3 is temperamental, opinionated, strong, loud, biased, stubborn and intolerable man. This man does not want to hear the opinions of the other jurors and is sure that the boy is guilty. He plays the part of the central negative in the group. When he doesn’t like what other people are saying he begins to yell and challenges that person speaking. He began to be dominating an d blocking towards the end. Even though he did not have a statement to backup his vote, he stood alone just because he didn’t want to be proved wrong.

The Importance of Knowledge Claims Essay - 1220 Words

The first question that needs to be is asked to complete this analysis is: How are knowledge claims created? A knowledge claim is a judgment of something we believe to be true with or without sufficient evidence. Knowledge claims are what we create as a means to justify and/or rationalize our beliefs and thoughts. Knowledge claims are created in an attempt to define and categorize those thoughts. One way knowledge claims are created is through the personal convictions reinforced by others. We live in a culture where we are dependent upon others to reassure us in our beliefs, and in doing so this allows us to form our own idea of what the truth is. For example, I have created knowledge claims based on the influence of others. When I once†¦show more content†¦Others know this because they can see it as well. The knowledge claim that my hair is black is truthful because it is based on the accurate sensory information provided to us by our own senses. In science, sensory inform ation also lends itself when coming to a conclusion in research. Scientists and researchers utilize their senses to be able to come to a conclusion in an experiment. Data collected from their experiment, from what they see in their research is what allows them to come to an accurate conclusion to be able to form an accurate knowledge claim with sufficient evidence to support it. The famous anecdote of an apple falling on Isaac Newtons head is widely credited with helping Newton discover the concept of gravity. His ability to see and his ability to touch allowed him to gather sensory information which led to the discovery of gravity and how it works. Historically speaking, the senses have provided the people of today with the ability to know about the past thanks to the information collected by others back then. This information in turn is developed into primary sources which is helpful in developing an accurate knowledge claim as the primary source comes directly from whomever was there to experience it firsthand. Clearly, it is essential that when forming a knowledge claim, we need to be able to trust our senses as well as have reliable sources to turn to to verify our beliefs. The second question that must beShow MoreRelatedGadamer’s On the Natural Inclination of Human Beings Toward Philosophy follows an idea that a1100 Words   |  5 Pagesof Human Beings Toward Philosophy follows an idea that a desire for knowledge, in researching philosophy and sciences, can be related to Platos thaumazein, the idea of wonder.

Business Law for Consumer Commission v TPG Internet- myassignmenthelp

Question: Discuss about theBusiness Law for Consumer Commission v TPG Internet. Answer: Issue Whether a contract was formed in this case, particularly on the basis of the offer and acceptance elements, or not? Rule Contract contains a promise whereby part A promises to fulfil a particular undertaking and party B pays party A, a consideration value, which is decided between A and B, for undertaking the promise. In order to form a contract, which has legal validity, there is a need for the presence of offer, acceptance, consideration, capacity and intent[1]. The very first step, which leads to the formation of contract, is the presence of an offer. It is essential to make a distinction between an offer and an invitation to treat. The offer shows that the parties A and B want to create a contract, where as the invitation to treat shows that the parties A and B just want to negotiate upon the terms of the contract. The newspaper advertisements or commercials are deemed as an invitation to treat and not an offer[2]. In Partridge v Crittenden[3], the defendants conviction was quashed as the advert was deemed as an invitation to treat. It is also important to demarcate between offer, invitation to treat and a request for information, as was held by the court in Harvey v Facey[4] where no separate offer was deemed to have been made. Upon an offer being made in a successful manner, the acceptance has to be attained on this offer. The acceptance has to be given by the party to which the offer had been made. So where the offer was made by A to B, B has to accept the offer. The offer can be revoked only till B does not accept it[5]. Also, there is a need to accept the offer in the manner in which it had been made, and if the terms are altered in the slightest of manner, it would result in a counter offer as was seen in Hyde v. Wrench[6], which would render the original offer useless. The acceptance date is taken to be such date when the acceptance communication is obtained by the offering party[7]. Though, the postal rules to acceptance is the exception of this rule as under this rule, the acceptance date is such date on which the letter containing the acceptance is posted by the accepting party. The raison d'tre behind this is that the postal office is given the status of the agent of the offering party and due to the operation of agency law, the acceptance by the postal office is to be considered as the acceptance by the offering party[8]. The date on which this letter reaches the offering party remains irrelevant. Upon the electronic communication, the Electronic Transaction Act, 1999[9] applies. The postal rules of acceptance are linked to the requirements of section 14 of this act. As per this section, the date and time on which the communication leaves the senders device, that is the date and time of the particular communication and not the date on which th e same reaches the receiver. This section is applicable for offer and acceptance both. Apart from these two elements, the formation of contract requires consideration as an element under which the parties mutually decide the value which has to be paid for the undertaken promise. There is a need for the consideration to have economic value for the contract to be valid[10]. The next requirement is to have the intention of forming legal relations. The parties also need to have the contractual capacity to create legal relations in terms of majority age and soundness of mind[11]. Application The facts of this case study are majorly concentrated upon the elements of offer and acceptance. The advert which Lianne saw in the newspaper, on the basis of Partridge v Crittenden, would be deemed as an invitation to treat as it invited quotes from the parties who wanted a party to be hosted. Section 14 of the Electronic Transaction Act and the postal rules of acceptance also play a crucial role in this case study. As the emails were exchanged in this case, on the basis of this section, the date of the communication would be the date on which it was sent and the date on which the receiver read it, would remain irrelevant. The email which was sent on 10 Jun, the very first one in the chain of emails, would be considered as a request for information on the basis of Harvey v Facey since Lianne only requested information under it. The reply to this email was also not an offer as only information was being swapped under this. The three hour afterwards email was the point where the offer was made. On this, a counter offer was made with reduced amount as there was a change in the terms of the original offer. Again, a counter offer was made with particular conditions and the higher consideration amount and this offer was valid for a specified time period only. The offer was made on 10 Jun so, it expired after seven day period on 17 Jun. Hence, it was not valid on 20 Jun when Mary stated that the price had changed. The communication of Lianne on 20 Jun would not be an acceptance. When Mary quoted $10,000 on 20 Jun that was when the new offer was made. And the acceptance was attained on this as Lianne sent an email regarding the same. However, later on she sent an email to revoke this acceptance, which would not be valid as the offer ahs to be revoked before acceptance is given. The reading or non-reading of the emails would remain irrelevant on the basis of postal rules of acceptance and section 14 of the Electronic Transaction Act. The value of consideration has already been established and the other elements of contract have been assumed as being present as the contrary to prove this is not present. This means that a contract had been created between the two parties. Conclusion To conclude, indeed a valid contract had been created between Lianne and Mary. Issue Whether Lianne has any rights under the Australian Consumer Law, or not? Rule The Competition and Consumer Act, 2010 was an act brought out in the nation, for protecting the consumers and for ensuring that the competition is properly followed in the nation. Under schedule 2 of this act, is the Australian Consumer law, which is the key legislation for safeguarding the consumers. A consumer is such a person, as per section 3 of ACL, who takes services or purchases goods to the value of $40,000 in the nation, for their own use or consumption. Through section 18, the businesses are prevented from indulging in misleading and deceptive conduct. And through section 29, the same restriction has been placed with regards to false or misleading representation. Application The facts of this case study show that Lianne is a consumer as she undertook the services of Mary and entered into a contract with her for a value of $9,500. These services were used for her personal party. And so, as per section 3, Lianne is a consumer. By not fulfilling the terms which were promised, Lianne was misled and deceived by Mary as she was provided with a different cuisine, instead of what was promised. Further, the space in the boat was falsely represented. This would mean that both sections 18 and 29 were contravened by Mary. Conclusion To conclude, Lianne is a consumer in this case, who had rights to sue Mary for breaching section 18 and 29 of the ACL. The invitation to treat and an offer are two terms which cause a lot of confusion in the daily lives of people. The confusion is due to the fact that at particular instances, the particular communication can be taken as one thing and at other instances, it could be deemed as the other one. This confusion can lead to certain liabilities for the businesses who give such adverts through the different mediums. In this discussion, the points have been put in favour of the care which needs to be undertaken by the businesses while creating the adverts to be published in hard copy and soft copy. In the first part of this discussion, Lianne reads a newspaper advertisement which was taken to be an invitation to treat based on a quoted case. The reason for holding this as an invitation to treat was because the judge in the case of Partridge v Crittenden had analysed the wordings of the advertisement and applied statutory rules of interpretation for taking out its meaning, which was ultimately deemed as an invitation to treat, instead of an offer[12]. Where a case of invitation to treat is established, there is no need for the parties to complete the sale and no liabilities are attracted on them as was seen in Pharmaceutical Society of Great Britain v Boots[13]. However, this is not the case with every advertisement. To make a demarcation between a particular advert being an invitation to treat and it being an offer, the wordings of such advert have to be considered. Unlike Partridge v Crittenden, in Carlill v Carbolic Smoke Ball Company[14] the court deemed that the advertisement was an offer. The difference between the two could be established in the context of the placed advertisement[15]. In the case of Carlill v Carbolic Smoke Ball Company, the company had given an advertisement in the newspaper where it promised to award the person who got the disease even when they had used the smoke ball produced by the company. The award money was 100. Carlill used this smoke ball and still got influenza so she went to the money and claimed the award money of 100. The company denied the claim on the basis that this was an invitation to treat. However, the court agreed with the plaintiff as they stated that the newspaper advert wordings were such where the offer could be accepted by simply acting upon it. And so, the court ordered the plaintiff to be paid the promised award money[16]. The advertisements are placed in newspapers and in this growing digital age, they are found more than often across the digital platforms. The adverts also include the one posted on billboards and on the buses. So, at every place where the businesses post their advertisements, they have to take care in printing their adverts. Whatever promises or offers they made under the advertisements, have to be drafted in a manner that they remain an invitation to treat and do no become an offer. In case an offer is made through such advertisements, liability would be attracted for the businesses as they would have to go forward with the contract when the offer is acted upon by the other party[17]. Apart from the liabilities which can be raised for the businesses for posting their advertisements under the contract law, the businesses can also be made liable for the adverts on the basis of the Australian Consumer Law. Australian Competition and Consumer Commission v TPG Internet Pty Ltd[18] is a leading example of this in which TPG had advertised a price for their product. However, this price was deemed as misleading and a breach of section 18 was established as the adverts did not disclose fully that the consumers had to pay additional sum at later stage as this additional sum was hidden from the published advertisement. To conclude the discussion which had been carried on till now, it becomes very clear that the businesses have to take special care when they place any advertisement through the different mediums. This is because these adverts can result in a contract, where this advert is an offer, instead of an invitation to treat. And in such cases, the businesses become bound by the contract and have to fulfil the obligations covered under the contract. Apart from this, the businesses also become liable under the other laws including the Australian Consumer Law. Hence, as was stated at the outset of this discussion, it is crucial that businesses take care while placing any advert, or would attract liabilities upon them. Bibliography A.

Taming of the Shrew1 Essay Example For Students

Taming of the Shrew1 Essay In William Shakespeares Taming of the Shrew, Katherine is not truly tamed because she simply follows Petruchios orders without changing her spirit. Petruchio gets his hands full when he marries Katherine. She is a very wild and rough woman who needs to be tamed. In the beginning of the story, Katherine is a very wild woman; her father speaks of her violent ways: For shame, thou hilding of a devilish spirit! (II, i., 27-28). Baptista, Katherines father, is obviously fed up with Katherine and her savage manners for him to utter such strong words to his daughter. Katherine is so feral that she will never be able to be tamed. Throughout the play, she remains this way. On the way to Biancas wedding, Petruchio threatens to turn back unless Katherine agrees that the moon is shining, and it is not the sun, as it truthfully is. We will write a custom essay on Taming of the Shrew1 specifically for you for only $16.38 $13.9/page Order now Hortensio, one of Petruchios friends, advises Katherine to consent to Petruchio: Hortensio: Say as he says, or we shall never go.Katherine: Forward, I pray, since we have come so fare, And be it moon, or sun, or what you please. (IV, v., 13-15)Katherine is becoming very smart at obeying Petruchio. She now understands how to get what she wants from him. Her spirit is still wild and untamed; however, she acts loyal to Petruchio on the surface to avoid suffering Petruchios punishments. By not changing her nature, Katherine shows Petruchio that he is not in charge. The men of the town of Padua need to find a man to marry Katherine to free her fair sister, Bianca. Katherines father will not allow Bianca to marry until the elder is married. Petruchio is talked into marrying Katherine, mostly for her fathers dowry. When Petruchio first meets Katherine and talks of marriage, she is very wild and she tries to run away from him: I chafe you if I tarry. Let me go. (II. i., 255). Katherine does not want to be with Petruchio. She is happy being by herself and making her sister miserable. She is a very independent woman, and she enjoys living up to her reputation. When Petruchio fails to listen to Katherine about what type of outfit she wants to wear to Biancas wedding, she is enraged: Why, sir, I trust I may have leave to speak, And speak I will. I am no child, no babe. Your betters have endured me say my mind, And if you cannot, best you stop your ears. My tongue will tell the anger of my heart, Or else my heart, concealing it, will break, And, rather than it shall, I will be free Even to the uttermost, as I please, in words. (IV, iii., 78-85). Katherine directly goes against her husband. She does not show him the respect a husband should receive. Katherine never changes her untamed ways; she stays wild at heart. Obviously, in William Shakespeares Taming of the Shrew, Katherine is never actually tamed by Petruchio. Bibliography:The Taming of the Shrew, by William Shakespeare

telescopes essays

telescopes essays The telescope has changed the world greatly by being able to make distant objects appear closer and more distinct. It helped scientists to discover things that could not be seen by the naked eye. For example, a lot of things in space would have not been discovered if it were not for the telescope. Also, it helped the world of eyesight. It would not only let you see objects from far away, it would also help you see if you had a problem with it. It could also be used for other things: hunting, war, and making new discoveries. What would the world be like without the telescope? I dont know what the world would be like, but I some very good reasons why it was good that the telescope was created. Before there was the telescope people had to make discoveries by judgment. They were not very accurate discoveries. They also had to just use the naked eye when they would have to use the naked eye when looking at distant objects that could have been easily seen by the telescope. The telescope was one of the main instruments of what has been called the Scientific Revolution of the seventeenth century. It revealed unsuspected phenomena in the heaves and had a profound influence on the controversy between followers of the traditional astronomy, the cosmos, and those who favored the naked eye. It was the first extension of mans senses and demonstrated that ordinary observers could see things that Aristotle had not dreamed of. It therefore helped shift authority in the observation of nature from men to instruments. In short, it was the prototype of modern scientific instruments. But the telescope was not the invention of scientists; rather, it was the product of craftsmen. For that reason, much of its origin is inaccessible to us since craftsmen were by large illiterate and therefore historically often invisible. Although the magnifying and diminishing properties of the convex and concave transparent objects was known in Antiq...

Reflexive Pronouns in Spanish

Reflexive Pronouns in Spanish Reflexive pronouns are used in Spanish and English whenever the subject of a verb is also its object. In other words, reflexive pronouns are used when the subject of a sentence is acting on itself. An example is the me in me veo (and the corresponding myself in I see myself), where the person seeing and the person seen are the same. Verbs used with a reflexive pronoun are known either as reflexive verbs or pronominal verbs. This lesson covers the reflexive pronouns that are used with verbs. Spanish also has reflexive pronouns used with prepositions. The 5 Reflexive Pronouns Used With Verbs Verbal reflexive pronouns are used in much the same way as direct-object and indirect-object pronouns; they typically precede the verb or can be attached to the infinitive, imperative verb, or gerund. Here are the verbal reflexive pronouns along with their English equivalents: me - myself - Me lavo. (I am washing myself.) Voy a elegirme. (I am going to choose myself.)te - yourself (informal) -  ¿Te odias? (Do you hate yourself?)  ¿Puedes verte? (Can you see yourself?)se - himself, herself, itself, themselves, yourself (formal), yourselves (formal), each other - Roberto se adora. (Roberto adores himself.) La nià ±a prefiere vestirse. (The girl likes to dress herself.) La historia se repite. (History repeats itself.) Se compran los regalos. (They are buying themselves gifts, or they are buying each other gifts.)  ¿Se afeita Ud.? (Do you shave yourself?) El gato se ve. (The cat sees himself.)nos - ourselves, each other - Nos respetamos. (We respect ourselves, or we respect each other.) No podemos vernos. (We cant see each other, or we cant see ourselves.)os - yourselves (informal, used primarily in Spain), each other - Es evidente que os querà ©is. (Its obvious that you love each other, or its obvious you love yourselves.) Podà ©is ayudaros . (You can help yourselves, or you can help each other.) As you can see from the above examples, the plural pronouns in Spanish can be translated using the English reflexive pronouns or the phrase each other. (Technically, grammarians would call the latter usage of the Spanish pronoun reciprocal rather than reflexive.) Usually, context will make clear the more likely translation. Thus, while nos escribimos conceivably could mean we write to ourselves, it most often would mean we write to each other. If necessary, a phrase can be added for clarification, such as in se golpean el uno a otro (they are hitting each other) and se golpean a sà ­ mismos (they are hitting themselves).

Further Education in UK - Essay Example Some FECs are funded directly; others receive money indirectly through a franchise agreement with a higher education institution, or as part of a consortium. Contact details and links to further information on FECs providing HE courses are available through the HERO web-site. The following list gives the 135 FECs that we are funding directly I am proud that my first White Paper as Secretary of State should be on the issue of education for our 14 to 19 year old.(http://195.194.167.100/unicoll/FE/). The reforms set out for further education are very much important. They are vital to UK economy equipping young people with the skills employers' need and the ability to go on learning throughout their lives. Reforms are vital for social justice giving us the chance to give break through the historic link between social back ground, educational achievement and life chances that have determined UK citizens as a nation. And most of all these are vital to each and every individual young person, whatever the needs of the young people or whatever they want to be. Young teenagers are tomorrow's leaders, entrepreneurs, parent and community servants, so we should take a special care for the children in the age group of 14 to 19; it is the age period when one needs guidance and help for selecting one's career. Build a system of 14 to 19 education that will do just that. A system that we can be proud of. And one that gives every young person the opportunities they need and deserve. Every child and every teenager has equal worth. We owe it to them to give them the chance to show what they can do, to make the most of their talents, to reach their potential. And the key to doing that is to design a system around them based on high standards, on choice and on meeting individuals' needs and aspirations. To deliver that system will take determination. It will take commitment. It will take the hard work of teachers, lecturers, other education professionals, employers, parents and all who work in or with our schools and colleges. It will require breaking down the artificial barriers between academic and vocational education. It will mean building on all that is good in our system and reforming what is not working. Building from the excellent work of Sir Mike Tomlinson and his Working Group on 14-19 Reform and from the work of the successful school and college partnerships we are already seeing in local communities. It charts a 10-year reform programme and the milestone s needed to achieve it. But more than those details and those milestones, it sets out a vision of what we want for children and teenagers what we want them to learn, the skills we want them to acquire, but above all the values we want them to have. The purpose of the education system is to help each and every individual reach their potential.

Fast Food Restaurants Assignment Example | Topics and Well Written Essays - 2000 words

Fast Food Restaurants - Assignment Example Therefore, in Fast Food restaurants industry, customer loyalty is built, earned and retained with the following components; Product quality, Product attributes, Brand name, Store environment (relates to customer experience with the restaurant and restaurant's ambiance), Service quality, Price, Promotion, Trust and Satisfaction. In this industry, a loyal customer means the person who avail's a restaurant's services, is highly satisfied with them, has a pleasant customer experience with the place, trusts the restaurant to provide high quality good food, considers product/service attributes to be excellent, considers the product/service quality as high, considers price to be worth the product/service offering, rates promotional activities to be highly attractive and goes for the brand name created by the restaurant, like McDonalds (Nezakati, 13). For fast food firms, customer loyalty is when a particular customer revisits their restaurant again and again and repurchases their service. M oreover, these are the customers who visit the restaurant very frequently, for instance a customer who eats at the restaurant twice every week. They are happy customers who give a positive feedback when asked about the food and they give generous tips to the waiters. Customer loyalty is measured by the revenue generated from a particular customer, a regular customer whose name every waiter would know or who could be recognized by face (Rehman et.al., 1-2). For customers, customer loyalty is the high level of satisfaction they receive from dining in a fast food restaurant. For them, customer loyalty is a product of high quality product/service that completely fulfills the customer expectations and satisfy their preferences or needs. For customers, to be a loyal consumer of a fast food restaurant's food, it is essential for the restaurant to provide them with a complete service experience. The ambiance of the place must be pleasant and enjoyable. Food must be of high quality and most importantly it must be hygienic and worth every penny they pay for it. The service must be prompt and efficient as customers do not like to wait a lot when it comes to food and restaurant staff must be hospitable and helpful since many at times customers ask for suggestions from the staff as to what they should order and what is the best dish they serve. So in a nutshell, for customers to be loyal they must be provided a high quality food service as for customers, customer loyalty is what an organization earns from the absolute satisfaction of a customer. It is all about meeting customer expectations and living up to them (Rehman et.al., 1-2). To be more specific, companies and customers define customer loyalty by dividing it into two types; attitudinal loyalty and behavioral loyalty. Attitudinal loyalty is a state of mind a customer is in which displays a positive preferential attitude of the customer towards a company's products/services. It simply depends on the customers' liking , if they like a certain brand, like in this case if they love McDonalds, they will even pay a premium price to buy the product compared to its lower priced competitor, for instance KFC in this case. Behavioral loyalty is simply dependent on the customer's conduct without any consideration of their attitude or preference.

Hero Myth - Achilles Essay Example for Free

Hero Myth Achilles Essay The concept of the hero is as old as myth itself. Throughout history both concepts have evolved together. Myths tell tales of the adventures of man, frequently the son of a god or goddess and a human, who is endowed with great promise and destined to perform great feats. Often these feats involve acts of rescue, war or protection. This heroic myth is rooted in the ideal of familial romance. Particularly during adolescence it sustains and expresses the identification of the ego with idealized imagery. The hero myths have been used for centuries to educate and train youths as parts of institutions and groups. One example of a hero is Achilles, made famous through Homer’s epic Illiad. While we may not look at myths today in the same ways as our ancient forebears, the hero myth is still alive and well in our culture today. Achilles was the hero of the Trojan war as related by Homer in the Illiad. He was the mightiest of the Trojan warriors. He began life as a demigod, the son of Peleus, the king of the Myrmidons and a mortal, and Thetis who was a Nereid. The Myrmidons were legendary warriors, very skilled and brave. Nereids are sea nymphs being the daughters of Nereus and Doris. Thetis was very concerned that her son was a mortal. Therefore she attempted to make him immortal. There are two stories of how she wet about this. The lesser-known story is that she burned him in a fire nightly and then healed his wounds with a magical ambrosia. The more well-known story is that she held him tightly by the heel and submersed him in the river Styx. This made his entire body invulnerable except for the spot on his heel where she held him while he was in the river. During Achilles’ boyhood, a seer named Calchas prophesied that Troy would not fall without help from Achilles. Knowing that he would die if he went to Troy, Thetis sent Achilles to the court of Lycomedes in Scyros. He was hidden there in the guise of a young girl. While at the court he had a romance with Deidameia who was the daughter of Lycomedes. The result was a son who was named Pyrrhus. The disguise finally came to an end when Odysseus exposed Achilles by placing arms and armor amongst a display of female garments and picked Achilles out when he was the only â€Å"female† to be interested in the war equipment. Achilles then willingly joined Odysseus on the journey to Troy. He led a host of his father’s Myrmidon troops in addition to his utor Phoenix and his friend Patroclus. Once in Troy, Achilles quickly gained the reputation as an undefeatable warrior. One of his most notable feats was the capture of 23 Trojan towns. One of these was Lyrnessos where he took a war prize in the form of a woman named Briseis. The central action of the Illiad was sparked when Agamemnon, the leader of the Greeks, was forced to give up his war-prize woman, Chryseis, by an oracle of Apollo. As compensation for the loss of Chryseis, Agamemnon took Briseis from Achilles. Thus enraged, Achilles refused to continue fighting for the Greeks. With Achilles’ withdrawal from the action, the war started to go badly for the Greeks and they offered large reparations to try to lure back their greatest warrior. Achilles continued to refuse to rejoin the war, however, he did agree to allow his close friend Patroclus to don his arms and armor and fight in his place. The next day Hector, a Trojan hero, mistook Patroclus for Achilles and killed Patroclus. Achilles was engulfed with rage at Hector and consumed by grief for his friend’s death. Thetis went to Hephaestus and obtained fabulous new armor for Achilles. Achilles recommenced fighting and killed Hector. Not satisfied with Hector’s death, Achilles used his chariot to drag the body before the walls of Troy and refused the corpse funeral rites. Hector’s father Priam, the king of Troy, went secretly to the Greek camp to beg the return of the body. Finally, Achilles relented and allowed Priam to take Hector’s remains. After Hector’s death time started to run out for Achilles. He continued to fight heroically and killed many Trojans as well as their allies. Eventually, Paris, who was another of Priam’s sons, enlisted the aid of Apollo and wounded Achilles in his weak spot – the heel – with an arrow. This caused Achilles death. The enduring legend from the story of Achilles has to do with the concept of the Achilles’ heel. An Achilles’ heel has come to mean that despite overall strength, there is a mortal weakness that can lead to one’s downfall. While the original myth refers to a physical weakness, in modern times it has come to reference other types of character flaws or qualities that can cause ruination. The concept of the hero has changed somewhat in our modern culture. Instead of daring people who buck trends and traditions in order to help their families, nations or cultures, today we tend to revere people like sports figures and actors. While we have the occasional government or political leader such as Winston Churchill, Martin Luther King or Nelson Mandela, most of what you hear about is who is making the most money due to their sports or acting ability. The concept of the sports figure hero can have some validity as these figures do occasionally overcome great odds and perform daring feats on the modern â€Å"battlefield†, i. e. , the sports arena. However, this is nothing compared to the feats of the ancient heros. Hero myths are powerful stories from ancient times. So powerful are they that they cross cultures and ages, continuing to influence us today. Achilles was one of the great heros of ancient times as the mightiest warrior of the Trojan war. While who we classify as a hero has changed in our modern societies, we still look to the concept today. We teach young people about heros as a method to inspire them. We look to our heros as adults to give us guidance and to give us something to guide our hopes and dreams. While modern heros may not be of Achilles’ status, they remain an integral part of our cultures.

Kate Chopins The Story of an Hour - A Big Story in a Small Space :: The Story of an Hour

Story of an Hour – A Big Story in a Small Space  Ã‚      Kate Chopin's "Story of an Hour", tells the story of a woman trapped in a repressive marriage, who wants desperately to escape. She is given that chance, quite by accident, and the story tells of the hour in which this freedom is given her. The story is very short (only two pages), so is interesting to look at as a minimalist piece of literature, and the surprise ending offers an opportunity to look at Chopin's use of foreshadowing. The story is very short, but every word has import in the story and each line has great depth of meaning. It is possible to infer a great deal about the woman's life, even though we are given very little on the surface. A telegraph and a railroad are mentioned in the first paragraph, so there is some idea of the time the story takes place. We are also given her married name and the full name of her husband. The fact that she is referred to only as "Mrs. Mallard", while her husband's full name is given, coupled with what we learn on the second page, gives some indication of the repression she's had to suffer through and the indignity society placed on woman in those times. We also learn in the first paragraph that she lives in a man's world, for, though it is her sister that tells her the news, it is her husband's friend who rushes over with the story. Even after his death, she is confined to the structures she adopted with married life, including the close friend's of her husband. It can also be assumed that Brently Mallard was fairly well off, because they live in a home with an upstairs, comfortable furnishings, and he has occasion and reason to travel. Also, they can afford a doctor's diagnosis that she has a "heart condition". The most important idea that is conveyed in the story is summed up in two sentences, near the end of the story, "There would be no powerful will bending hers in that blind persistence with which men and women believe they have a right to impose a private will upon a fellow-creature. A kind intention or a cruel intention made the act seem no less a crime as she looked upon it in that brief moment of illumination".

Report on the Film “Black Cat, White Cat” by Emir Custurica Essay

have chosen to watch and report on the film â€Å"Black Cat, White Cat† by Emir Custurica for several reasons. Firstly, Custurica is a globally famous filmmaker, known in the US for his â€Å"Arizona Dream†. Secondly, Custurica does pay much attention to matters of culture in his films, so his works are very informative. Thirdly the characters of â€Å"Black Cat, White Cat† belong to different peoples and cultures, including Serbians, Gypsies and Bulgarians. So the film tells enough about cultural and cross-cultural communications. Produced in 1998, the film is a kind of romantic comedy telling a story of several young people in search of their love in the world of gangsters and smugglers. One of those smugglers named Matko Destanov owes money to a gangster named Dadan. Dadan is eager to find a husband for Afrodita – his midget sister and he proposes to settle the debt by marriage of Matko’s son Zare with his sister. However, Zare is in love with another girl named Ida, and Afrodita dreams o another man. After numerous funny and dangerous adventures all of the young people find their happiness, and Dadan finds himself in manure both in metaphorical and ordinary sense. The film is very ironic and easy to watch as a family comedy. As I have already noticed, the film tells much about cultural communications. Firstly these are family and friendship. The characters seem to be very family-oriented and â€Å"beautiful friendship† is one of the core motifs of the story. Young people dream of a family and stable relationships, older people desire to make their children happy as Zare’s grandfather and even such a savage man as Dadan wishes to do the will of his parents even though through violence. Personal relations are basic forces driving the characters in life, business and even crime. They rely upon help of their pals and relatives in virtually every action they take, thusly playing a tricky party game – each for own purposes but considering the will of the others. This can be illustrated by relations of Zare with his grandfather. Zare loves his grandfather and helps him to escape from hospital to return to his bacchanalian lifestyle, and the thankful grandfather gives all his money to Zare. Such approach to personal relations is full of traditionalism and is pretty different from the present situation in this country. Another cultural aspect, which might seem rather evil in this country is attitude of characters towards law. Throughout the film it may seem that there is no law and legal formalities at all. Customers are easily bribed, medical personnel is unable to control the patients, gangsters behave as actual rulers and an official solemnizing a marriages passively does everything what he is ordered to do, even knowing that marriage between Zare and Afrodita is forcible. However, the characters actually do not feel any discomfort from absence of formalities. Law is replaced by aforementioned personal relations, and perhaps they would feel unhappy from presence of legal obligations rather from absence of such obligations. There are many interesting minor cultural details in the film such as marriage customs, costumes, language features and other which, being combined together, create a fascinating impression of involvement in other culture. Films like â€Å"Black Cat, White Cat† cause spectators to become interested in strange lifestyles and habits forming an idea of global cultural diversity.

Gothic Literature Essay

American Gothic Literature is a chance to experience the bizarre and scary natures of an individual. Authors such as Hawthorne, Faulkner and O’conner use the written word to paint these gothic images in the minds of their readers. Supernatural appearances and motifs such as ghosts and monsters, are embodiments of people’s deepest fears and longings. Authors often use creepy settings because it is what revolves around the event. For example, In The Cask of Amontillado it creates a creepy setting, â€Å"I busied myself among the pile of bones of which i have before spoken, throwing them aside†(83).This gives us a suspicious and vigorous feeling of who’s pile of bones that is? It creates an idea that murder has occurred. Another ideal of a direful set is in the story The Raven when the narrator says, â€Å"A distinctly dying ember wrought its ghost upon the floor†(467). He clearly tells us what he remembers in December. About the fire tugging its ghost upon the floor. The dreadful settings makes the appearance of it’s leading to the event. Descriptions of characters let’s us know what the character will or may do.For example, In A Rose for Emily, the character Emily demands, â€Å"I want arsenic†. She demands wantin arsenic letting us predict what she may do with it. It gives us clues making a Gothic story more interesting. In Addition, the author of The Masque of the Red Death wrote, â€Å"His vesture was dabbed in blood and his broad brow, with the scarlet horror†(122). The Masque of Red Death is about to attack showing himself in blood with his scarlet horror. It scares the people primarily as to just killing them for a more captivating event .By creating an obscure character, people attend achieving Gothic greatness. The event is the climax of the story with many unexpected tragic stories. For example, in Good Country People Hulga yells at at Manly Pointer, â€Å"‘Give me my leg! ’ sh e screamed and tried to lunge for it, but he pushed her down easily†(12). Hulga did not expect for Manly Pointer to steal her bogus leg. He has always presented himself as a good Christian that is nothing but noble. Furthermore, an unforeseen event makes occurs in A Rose For Emily, â€Å"Then we noticed that in the second pillow was the indentation of a head.One of us lifted something from it, and leaning forward, that faint and invisible dust, dry and acrid in the nostrils, we saw a long strand iron-gray hair†(12). Even though Miss Emily aparted herself from the outside, her murder of Homer was sudden. Miss Emily having Homer’s dead body for so many years conveys there is more than just a solitary feeling in her. Death is usually where the story ends in a Gothic story to follow the sequence of fascinating menacing literature. Abnormal semblance of specters draw the structure of the people’s inmost anxiety and desire.

Kennedy, American University Speech, June 10, 1963. The Cold War was a time in American History during the twentieth century where the Communist nations were fighting against the non-Communist nations.However, the main countries involved, or the ones leading the two sides were the United States and Russia.The United States led the fight against Communist nations, like Russia.But these intense rivalries didnt just go on in the type of government that should be used or in who could develop the most advanced and most powerful nuclear weapon of the time.This rivalry went into the culture of American societies.The Russians were always being viewed as the toughest rival and the team to beat according to the U.S.It is similar to how teams think of the defending champions in a sport.The team playing the defending champions wants to come out hyped up and with their A-game every time they are competing with them.Another impact it had on the American society was how people started acting and thinking.In many of the movies and television shows of the time, most people wouldnt have noticed, but the directors and producers were hiding subliminal messages in them.

Pathway to Personal Growth and Development for Teachers

Pathway to Personal Growth and Development for Teachers It takes a lot of hard work and dedication to be an effective teacher. Like other careers, there are those who are more natural at it than others. Even those with the most natural teaching ability must put in the time necessary to cultivate their innate talent. Personal growth and development is a critical component that all teachers must embrace in order to maximize their potential. There are several different ways that a teacher can enhance their personal growth and development. Most teachers will use a combination of these methods to solicit valuable feedback and information that will guide their teaching career. Some teachers may prefer one method over another, but each of the following has been proven to be valuable in their overall development as a teacher. Advanced Degree Earning an advanced degree in an area within education is a fantastic way to gain a fresh perspective. It is also an excellent way to learn about the newest educational trends. It provides tremendous networking opportunities, can lead to a pay increase, and allows you to specialize in an area where you may have more interest. Going this route is not for everyone. It can be time-consuming, costly, and sometimes overwhelming as you try to balance the other aspects of your life with those of earning a degree. You must be organized, self-motivated, and adept at multi-tasking to use this as a successful way to improve yourself as a teacher. Advice/Evaluations from Administrators Administrators by nature should be excellent resources of advice for teachers. Teachers should not be afraid to seek help from an administrator. It is essential that administrators are accessible for teachers when they need something. Administrators are typically experienced teachers themselves who should be able to provide a wealth of information. Administrators, through teacher evaluations, are able to observe a teacher, identify strengths and weaknesses, and offer suggestions that when followed will lead to improvement. The evaluation process provides natural collaboration where the teacher and administrator can ask questions, exchange ideas, and offer suggestions for improvement. Experience Experience is perhaps the greatest teacher. No amount of training can truly prepare you for the adversity that a teacher can face in the real world. First year teachers often wonder what they have gotten themselves into over the course of that first year. It can be frustrating and disheartening, but it does become easier. A classroom is a laboratory and teachers are chemists constantly tinkering, experimenting, and mixing things up until they find the right combination that works for them.  Each day and year brings about new challenges, but experience allows us to adapt quickly and make changes ensuring that things continue to operate efficiently. Journaling Journaling can provide valuable learning opportunities through self-reflection. It allows you to capture moments in your teaching career that may be beneficial to reference at other points along the way. Journaling does not have to take a lot of your time. 10-15 minutes a day can provide you with a lot of valuable information.  Learning opportunities arise almost daily, and journaling allows you to encapsulate these moments, reflect on them at a later time, and make adjustments that can help you become a better teacher. Literature There is an overabundance of books and periodicals dedicated to teachers. You can find a plethora of terrific books and periodicals to help improve in any area you may struggle with as a teacher. You can also find several books and periodicals that are inspirational and motivational in nature. There are excellent content driven books and periodicals that can challenge how you teach critical concepts. You will probably not agree with every facet of every book or periodical, but most offer sensational tidbits that we can apply to ourselves and to our classrooms. Asking other teachers, talking to administrators, or doing a quick online search can provide you with a good list of must-read literature. Mentoring Program Mentoring can be an invaluable tool for professional growth and development. Every young teacher should be paired with a veteran teacher. This relationship can prove to be beneficial for both teachers so long as both sides keep an open mind. Young teachers can lean on a veteran teacher’s experience and knowledge while veteran teachers can gain a fresh perspective and insight into the newest educational trends. A mentoring program provides teachers with a natural support system where they are able to seek feedback and guidance, exchange ideas, and vent at times. Professional Development Workshops/Conferences Professional development is a mandatory component of being a teacher.  Every state requires teachers to earn a certain number of professional development hours each year. Great professional development can be critical to the overall development of a teacher. Teachers are presented with professional development opportunities covering varying topics throughout the course of each year. Great teachers recognize their weaknesses and attend professional development workshops/conferences to improve these areas. Many teachers commit a portion of their summer to attending professional development workshops/conferences. Workshops/conferences also provide teachers with invaluable networking opportunities that can further enhance their overall growth and improvement. Social Media Technology is changing the face of education inside and outside of the classroom. Never before have teachers been able to make the global connections that they are able to make now. Social media such as Twitter, Facebook, Google , and Pinterest have created a global exchange of ideas and best practices amongst teachers. Personal Learning Networks (PLN) are providing teachers with a new avenue for personal growth and development. These connections provide teachers with a vast array of knowledge and information from other professionals across the globe. Teachers struggling in a particular area are able to ask their PLN for advice. They quickly receive responses with valuable information they can use for improvement. Teacher-Teacher Observations Observations should be a two-way street. Doing the observing and being observed are equally valuable learning tools. Teachers should be open to allowing other teachers in their classroom on a regular basis. It is necessary to note that this will not work if either teacher is egotistical or easily offended. Every teacher is different. They all have their individual strengths and weaknesses. During observations, the observing teacher is able to take notes detailing the other teacher’s strength and weaknesses. Later they can sit down together and discuss the observation. This provides a collaborative opportunity for both teachers to grow and improve. The Internet The Internet provides unlimited resources to teachers with the click of a mouse. There are millions of lesson plans, activities, and information available online for teachers. Sometimes you have to filter everything to find the highest quality content, but search long enough and you will find what you are looking for. This instant access to resources and content makes teachers better. With the Internet, there is no excuse for failing to provide your students with the highest quality lessons. If you need a supplemental activity for a particular concept, you can find likely find it quickly. Sites like YouTube, Teachers Pay Teachers, and Teaching Channel offer quality educational content that can improve teachers and their classrooms.

Color Research Paper Example | Topics and Well Written Essays - 1250 words

Color - Research Paper Example Color may be quantified and described by the extent to which they stimulate different types of cone cells (Travis, 2003). This is because color perception stems from different spectrum sensitivity of various cone cells in the retina to various parts of the spectrum. The physiological or physical color quantifications do not fully describe the color appearance and its psychophysical perception. The science of color is referred to as chromatography, color science or chromatics (Farndon, 2003). It involves color perception by the brain and human eye. Human perception of color originates from composites of light, photons’ energy spectrum entering the eye. The retina contains photosensitive cells on the back of the eye’s the inner surface. These photosensitive cells are composed of pigments absorbing visible light (Savage, 1998). There are two classes of photosensitive cells: cones and rods. Cones are responsible for human ability to distinguish between various colors (Klein er, 2004). On the other hand, the rods sense light intensity variations and are effective in dim light. Rods sense the flux of no photon energy, the incident photons. Therefore, whenever there is a dim light, human eye do not perceive colored objects as shades of color, but as shades of grey (Travis, 2003). Diagram of color and light Perception of color in the retina is done by photoreceptor cones which are sensitive to photons whose energy widely extend beyond the green, blue, and red spectrum portions (Kleiner, 2004). Color vision is often possible because of the differing photon energy sensitivity of the sets of cones (Savage, 1998). For every flux of photons or color signal, a ration of response in the different sets of cones is triggered. This ration is what permits color perception. During the day, human vision is effectively mostly in the blue-green where the spectrum of the sun is in its maximum region (Travis, 2003). Color sensation primarily depends on light composition, a mixture of colored light and white light (in itself can be wavelength mixture, like purple’s case) (Farndon, 2003). The colored light may have dominant hue or wavelength. The degree to which the wavelength dominates is referred to as chroma, saturation. This saturation, chroma decreases as the white light deletes the wavelength. There are 3 receptors that respond to various wavelengths in the eye. This results in attempts to chart colors via e primary lights mixture. A good number of colors are produces through mixing lights originating from the 3 primary lights. However, not all colors can be produced in this manner (Savage, 1998). Color vision development in human beings is an interesting process of evolution (Kleiner, 2004). The human eye is not in a linear straightforward development. Development of color vision begins as a light sensitive pigment and then differentiates on a smaller creature to create structures that are sensitive to light (Savage, 1998). These light se nsitive structures disperse in the forming eyeball and turns to be the retina. Initially, retina was like a moving sensor. However, it developed the ability to delineate fine details and to see color. The evolution of the eye and color perception is a standard development seen in all vertebrates and many non-vertebrates. So what is color? Why does retina develop ability to see color? (Farndon, 2003). Color is a visual perception that corresponds in human to the categories referred to as blue,

Digital Voltmeter Using An 8051 Microcontroller Computer Science Essay

Digital Voltmeter Using An 8051 Microcontroller Computer Science Essay A voltmeter finds its importance wherever voltage is to be measured. A  voltmeter  is an instrument used for measuring the  electrical potential  difference between two points in an electric circuit. Analog voltmeters move a pointer across a scale in proportion to the voltage of the circuit. General purpose analog voltmeters may have an accuracy of a few per cent of full scale, and are used with voltages from a fraction of a volt to several thousand volts. Digital voltmeters give a numerical display of voltage by use of analog to digital converter. Digital meters can be made with high accuracy, typically better than 1%. Specially calibrated test instruments have higher accuracies, with laboratory instruments capable of measuring to accuracies of a few parts per million. Meters using  amplifiers  can measure tiny voltages of micro-volts or less. Digital voltmeters (DVMs) are usually designed around a special type of  analog-to-digital converter  called an  integrating converter. Voltmeter accuracy is affected by many factors, including temperature and supply voltage variations. To ensure that a digital voltmeters reading is within the manufacturers specified tolerances, they should be periodically calibrated. Digital voltmeters necessarily have input amplifiers, and, like vacuum tube voltmeters, generally have a constant input resistance of 10 mega-ohms regardless of set measurement range. This project aims at building a Digital Voltmeter using an 8051 microcontroller. All the data accessed and processed by the microcontroller is the digital data. And thus, the usage of an analog-to-digital converter finds its necessity here. A standard analog-to-digital converter ADC0804 is used in the current project. The input voltage (which is the analog input) is restricted to be in the range of 0-15V. The processed data in the 8051 is used to drive a display output on a LCD display unit. The display is in the form of digits and is accurate to a value of one decimal. The input voltage is desired to be that of a DC voltage for steady observations of the voltage value on the LCD panel. Rather, if an AC input voltage is given at the input terminals, the output varies indefinitely as is the nature of AC voltage. Thus, the instantaneous value of the AC voltage is not steadily shown on the LCD panel. COMPONENTS Following is the entire set of the components used to build the Digital Voltmeter: Microcontroller, AT89S52 Analog-to-Digital Converter, ADC0804 161 LCD Oscillator circuit for the microcontroller 12MHz Crystal Capacitor 33pF Capacitors Voltage divider circuit/ Input terminals 200k, 100k Resistors 100nF Capacitor ADC Clock Circuit 10k Resistor 150pF Capacitor 100k Potentiometer (to adjust the back-light of the LCD) Description of the Components used Microcontroller, AT89S52 Æ’Â   The AT89S51 is a low-power, high-performance CMOS 8-bit microcontroller with 4K bytes of In-System Programmable Flash memory. The device is manufactured using Atmels high-density non-volatile memory technology and is compatible with the industry-standard 80C51 instruction set and pin-out. The on-chip Flash allows the program memory to be reprogrammed in-system or by a conventional non-volatile memory programmer. By combining a versatile 8-bit CPU with In-System Programmable Flash on a monolithic chip, the Atmel AT89S51 is a powerful microcontroller which provides a highly-flexible and cost-effective solution to many embedded control applications. The AT89S51 provides the following standard features: 4K bytes of Flash, 128 bytes of RAM, 32 I/O lines, Watchdog timer, two data pointers, two 16-bit timer/counters, a five-vector two-level interrupt architecture, a full duplex serial port, on-chip oscillator, and clock circuitry. In addition, the AT89S51 is designed with static logic for operation down to zero frequency and supports two software selectable power saving modes. The Idle mode stops the CPU while allowing the RAM, timer/counters, serial port, and interrupt system to continue functioning. The Power-down mode saves the RAM con-tents but freezes the oscillator, disabling all other chip functions until the next external interrupt or hardware reset. Pin configuration of the AT89S52 is as follows: 40-Lead PDIP VCC Supply voltage. GND Ground. Port 0 Port 0 is an 8-bit open drain bi-directional I/O port. As an output port, each pin can sink eight TTL inputs. When 1s are written to port 0 pins, the pins can be used as high-impedance inputs. Port 0 can also be configured to be the multiplexed low-order address/data bus during accesses to external program and data memory. In this mode, P0 has internal pull-ups. Port 0 also receives the code bytes during Flash programming and outputs the code bytes during program verification. External pull-ups are required during program verification. Port 1 Port 1 is an 8-bit bi-directional I/O port with internal pull-ups. The Port 1 output buffers can sink/source four TTL inputs. When 1s are written to Port 1 pins, they are pulled high by the internal pull-ups and can be used as inputs. As inputs, Port 1 pins that are externally being pulled low will source current (IIL) because of the internal pull-ups. Port 1 also receives the low-order address bytes during Flash programming and verification. P1.5 MOSI (used for In-System Programming) P1.6 MISO (used for In-System Programming) P1.7 SCK (used for In-System Programming) Port 2 Port 2 is an 8-bit bi-directional I/O port with internal pull-ups. The Port 2 output buffers can sink/source four TTL inputs. When 1s are written to Port 2 pins, they are pulled high by the internal pull-ups and can be used as inputs. As inputs, Port 2 pins that are externally being pulled low will source current (IIL) because of the internal pull-ups. Port 2 emits the high-order address byte during fetches from external program memory and during accesses to external data memory that use 16-bit addresses (MOVX @ DPTR). In this application, Port 2 uses strong internal pull-ups when emitting 1s. During accesses to external data memory that use 8-bit addresses (MOVX @ RI), Port 2 emits the contents of the P2 Special Function Register. Port 2 also receives the high-order address bits and some control signals during Flash programming and verification. Port 3 Port 3 is an 8-bit bi-directional I/O port with internal pull-ups. The Port 3 output buffers can sink/source four TTL inputs. When 1s are written to Port 3 pins, they are pulled high by the internal pull-ups and can be used as inputs. As inputs, Port 3 pins that are externally being pulled low will source current (IIL) because of the pull-ups. Port 3 receives some control signals for Flash programming and verification. Port 3 also serves the functions of various special features of the AT89S51, as shown in the following table. Alternate functions of port 3, P3.0 RXD (serial input port) P3.1 TXD (serial output port) P3.2 INT0 (external interrupt 0) P3.3 INT1 (external interrupt 1) P3.4 T0 (timer 0 external input) P3.5 T1 (timer 1 external input) P3.6 WR (external data memory write strobe) P3.7 RD (external data memory read strobe) RST Reset input. A high on this pin for two machine cycles while the oscillator is running resets the device. This pin drives High for 98 oscillator periods after the Watchdog times out. The DIS-RTO bit in SFR AUXR (address 8EH) can be used to disable this feature. In the default state of bit DISRTO, the RESET HIGH out feature is enabled. ALE/PROG Address Latch Enable (ALE) is an output pulse for latching the low byte of the address during accesses to external memory. This pin is also the program pulse input (PROG) during Flash programming. In normal operation, ALE is emitted at a constant rate of 1/6 the oscillator frequency and may be used for external timing or clocking purposes. Note, however, that one ALE pulse is skipped during each access to external data memory. If desired, ALE operation can be disabled by setting bit 0 of SFR location 8EH. With the bit set, ALE is active only during a MOVX or MOVC instruction. Otherwise, the pin is weakly pulled high. Setting the ALE-disable bit has no effect if the microcontroller is in external execution mode. PSEN Program Store Enable (PSEN) is the read strobe to external program memory. When the AT89S51 is executing code from external program memory, PSEN is activated twice each machine cycle, except that two PSEN activations are skipped during each access to external data memory. EA/VPP External Access Enable. EA must be strapped to GND in order to enable the device to fetch code from external program memory locations starting at 0000H up to FFFFH. Note, however, that if lock bit 1 is programmed, EA will be internally latched on reset. EA should be strapped to VCC for internal program executions. This pin also receives the 12-volt programming enable voltage (VPP) during Flash programming. XTAL1 Input to the inverting oscillator amplifier and input to the internal clock operating circuit. XTAL2 Output from the inverting oscillator amplifier. Memory Organisation, Program Memory: If the EA pin is connected to GND, all program fetches are directed to external memory. On the AT89S51, if EA is connected to VCC, program fetches to addresses 0000H through FFFH are directed to internal memory and fetches to addresses 1000H through FFFFH are directed to external memory. Data Memory: The AT89S51 implements 128 bytes of on-chip RAM. The 128 bytes are accessible via direct and indirect addressing modes. Stack operations are examples of indirect addressing, so the 128 bytes of data RAM are available as stack space. Interrupts: The AT89S51 has a total of five interrupt vectors: two external interrupts (INT0 and INT1), two timer interrupts (Timers 0 and 1), and the serial port interrupt. Each of these interrupt sources can be individually enabled or disabled by setting or clearing a bit in Special Function Register IE. IE also contains a global disable bit, EA, which disables all interrupts at once. The Timer 0 and Timer 1 flags, TF0 and TF1, are set at S5P2 of the cycle in which the timers overflow. The values are then polled by the circuitry in the next cycle. ADC0804 Æ’Â   The ADC080X family are CMOS 8-Bit, successive approximation A/D converters which use a modified potentiometric ladder and are designed to operate with the 8080A control bus via three-state outputs. These converters appear to the processor as memory locations or I/O ports, and hence no interfacing logic is required. The differential analog voltage input has good common-mode-rejection and permits offsetting the analog zero input voltage value. In addition, the voltage reference input can be adjusted to a low encoding any smaller analog voltage span to the full 8 bits of resolution. The functional diagram of the ADC080X series of A/D converters operates on the successive approximation principle. Analog switches are closed sequentially by successive-approximation logic until the analog differential input voltage [VlN(+) VlN(-)] matches a voltage derived from a tapped resistor string across the reference voltage. The most significant bit is tested first and after 8 comparisons (64 clock cycles), an 8- bit binary code (1111 1111 = full scale) is transferred to an output latch. The normal operation proceeds as follows. On the high-to-low transition of the WR input, the internal SAR latches and the shift-register stages are reset, and the INTR output will be set high. As long as the CS input and WR input remain low, the A/D will remain in a reset state. Conversion will start from 1 to 8 clock periods after at least one of these inputs makes a low to high transition. After the requisite number of clock pulses to complete the conversion, the INTR pin will make a high- to-low transition. This can be used to interrupt a processor, or otherwise signal the availability of a new conversion. A RD operation (with CS low) will clear the INTR line high again. The device may be operated in the free-running mode connecting INTR to the WR input with CS = 0. To ensure start-up under all possible conditions, an external WR pulse is required during the first power-up cycle. A conversion in process can be interrupted by issuing a second start command. Digital Operation The converter is started by having CS and WR simultaneously low. This sets the start flip-flop (F/F) and the resulting 1 level resets the 8-bit shift register, resets the Interrupt (INTR) F/F and inputs a 1 to the D flip-flop, DFF1, which is at the input end of the 8-bit shift register. Internal clock signals then transfer this 1 to the Q output of DFF1. The AND gate, G1, combines this 1 output with a clock signal to provide a reset signal to the start F/F. If the set signal is no longer present (either WR or CS is a 1), the start F/F is reset and the 8-bit shift register then can have the 1 clocked in, which starts the conversion process. If the set signal were to still be present, this reset pulse would have no effect (both outputs of the start F/F would be at a 1 level) and the 8-bit shift register would continue to be held in the reset mode. This allows for asynchronous or wide CS and WR signals. After the 1 is clocked through the 8-bit shift register (which completes the SAR ope ration) it appears as the input to DFF2. As soon as this 1 is output from the shift register, the AND gate, G2, causes the new digital word to transfer to the Three-State output latches. When DFF2 is subsequently clocked, the Q output makes a high-to-low transition which causes the INTR F/F to set. An inverting buffer then supplies the INTR output signal. When data is to be read, the combination of both CS and RD being low will cause the INTR F/F to be reset and the three state output latches will be enabled to provide the 8-bit digital outputs. Digital Control Inputs The digital control inputs (CS, RD, and WR) meet standard TTL logic voltage levels. These signals are essentially equivalent to the standard A/D Start and Output Enable control signals, and are active low to allow an easy interface to microprocessor control busses. For non-microprocessor based applications, the CS input (pin 1) can be grounded and the standard A/D Start function obtained by an active low pulse at the WR input (pin 3). The Output Enable function is achieved by an active low pulse at the RD input (pin 2). Analog Operation The analog comparisons are performed by a capacitive charge summing circuit. Three capacitors (with precise ratioed values) share a common node with the input to an autozeroed comparator. The input capacitor is switched between VlN(+) and VlN(-), while two ratioed reference capacitors are switched between taps on the reference voltage divider string. The net charge corresponds to the weighted difference between the input and the current total value set by the successive approximation register. A correction is made to offset the comparison by 1/2 LSB. Analog Differential Voltage Inputs and Common- Mode Rejection This A/D gains considerable applications flexibility from the analog differential voltage input. The VlN(-) input (pin 7) can be used to automatically subtract a fixed voltage value from the input reading (tare correction). This is also useful in 4mA 20mA current loop conversion. In addition, common-mode noise can be reduced by use of the differential input. The time interval between sampling VIN(+) and VlN(-) is 41/2 clock periods. There is maximum error voltage due to this slight time difference between the input voltage samples. The allowed range of analog input voltage usually places more severe restrictions on input common-mode voltage levels than this. An analog input voltage with a reduced span and a relatively large zero offset can be easily handled by making use of the differential input. Analog Input Current The internal switching action causes displacement currents to flow at the analog inputs. The voltage on the on-chip capacitance to ground is switched through the analog differential input voltage, resulting in proportional currents entering the VIN(+) input and leaving the VIN(-) input. These current transients occur at the leading edge of the internal clocks. They rapidly decay and do not inherently cause errors as the on-chip comparator is strobed at the end of the clock period. Input Bypass Capacitors Bypass capacitors at the inputs will average these charges and cause a DC current to flow through the output resistances of the analog signal sources. This charge pumping action is worse for continuous conversions with the VIN(+) input voltage at full scale. For a 640kHz clock frequency with the VIN(+) input at 5V, this DC current is at a maximum of approximately 5uA. Therefore, bypass capacitors should not be used at the analog inputs or the VREF/2 pin for high resistance sources (>1kOhm.) If input bypass capacitors are necessary for noise filtering and high source resistance is desirable to minimize capacitor size, the effects of the voltage drop across this input resistance, due to the average value of the input current, can be compensated by a full scale adjustment while the given source resistor and input bypass capacitor are both in place. This is possible because the average value of the input current is a precise linear function of the differential input voltage at a constant conversion rate. Input Source Resistance Large values of source resistance where an input bypass capacitor is not used will not cause errors since the input currents settle out prior to the comparison time. If a low-pass filter is required in the system, use a low-value series resistor for a passive RC section or add an op amp RC active low-pass filter. For low-source-resistance applications, a 0.1uF bypass capacitor at the inputs will minimize EMI due to the series lead inductance of a long wire. A 100Ohm series resistor can be used to isolate this capacitor (both the R and C are placed outside the feedback loop) from the output of an op amp, if used. Stray Pickup The leads to the analog inputs (pins 6 and 7) should be kept as short as possible to minimize stray signal pickup (EMI). Both EMI and undesired digital-clock coupling to these inputs can cause system errors. The source resistance for these inputs should, in general, be kept below 5kÃŽÂ ©. Larger values of source resistance can cause undesired signal pickup. Input bypass capacitors, placed from the analog inputs to ground, will eliminate this pickup but can create analog scale errors as these capacitors will average the transient input switching currents of the A/D (see Analog Input Current). This scale error depends on both a large source resistance and the use of an input bypass capacitor. This error can be compensated by a full scale adjustment of the A/D (see Full Scale Adjustment) with the source resistance and input bypass capacitor in place, and the desired conversion rate. Reference Voltage Span Adjust For maximum application flexibility, these A/Ds have been designed to accommodate a 5V, 2.5V or an adjusted voltage reference. This has been achieved in the design of the IC. Notice that the reference voltage for the IC is either 1/2 of the voltage which is applied to the V+ supply pin, or is equal to the voltage which is externally forced at the VREF/2 pin. This allows for a pseudo-ratiometric voltage reference using, for the V+ supply, a 5V reference voltage. Alternatively, a voltage less than 2.5V can be applied to the VREF/2 input. The internal gain to the VREF/2 input is 2 to allow this factor of 2 reduction in the reference voltage. Zero Error The zero of the A/D does not require adjustment. If the minimum analog input voltage value, VlN(MlN), is not ground, a zero offset can be done. The converter can be made to output 0000 0000 digital code for this minimum input voltage by biasing the A/D VIN(-) input at this VlN(MlN) value. This utilizes the differential mode operation of the A/D. The zero error of the A/D converter relates to the location of the first riser of the transfer function and can be measured by grounding the VIN(-) input and applying a small magnitude positive voltage to the VIN(+) input. Zero error is the difference between the actual DC input voltage which is necessary to just cause an output digital code transition from 0000 0000 to 0000 0001 and the ideal 1/2 LSB value (1/2 LSB = 9.8mV for VREF/2 = 2.500V). Full Scale Adjust The full scale adjustment can be made by applying a differential input voltage which is 11/2 LSB down from the desired analog full scale voltage range and then adjusting the magnitude of the VREF/2 input (pin 9) for a digital output code which is just changing from 1111 1110 to 1111 1111. When offsetting the zero and using a span-adjusted VREF/2 voltage, the full scale adjustment is made by inputting VMlN to the VIN(-) input of the A/D and applying a voltage to the VIN(+) input. Clocking Option The clock for the A/D can be derived from an external source such as the CPU clock or an external RC network can be added to provide self-clocking. The CLK IN (pin 4) makes use of a Schmitt trigger. Heavy capacitive or DC loading of the CLK R pin should be avoided as this will disturb normal converter operation. Loads less than 50pF, such as driving up to 7 A/D converter clock inputs from a single CLK R pin of 1 converter, are allowed. For larger clock line loading, a CMOS or low power TTL buffer or PNP input logic should be used to minimize the loading on the CLK R pin (do not use a standard TTL buffer). Restart During a Conversion If the A/D is restarted (CS and WR go low and return high) during a conversion, the converter is reset and a new conversion is started. The output data latch is not updated if the conversion in progress is not completed. The data from the previous conversion remain in this latch. Continuous Conversions In this application, the CS input is grounded and the WR input is tied to the INTR output. This WR and INTR node should be momentarily forced to logic low following a power-up cycle to insure circuit operation. Interfacing the Microcontroller Interfacing the ADC0804 with 8051 Æ’Â   As shown in the typica circuit, ADC0804 can be interfaced with any microcontroller. A minimum of 11 pins are required to interface the ADC0804, eight for data pins and 3 for control pins. As shown in the typical circuit the chip select pin can be made low if you are not using the microcontroller port for any other  peripheral  (multiplexing). There is a  universal  rule to find out how to use an IC. All we need is the datasheet of the IC we are working with and a look at the  timing diagram  of the IC which shows how to send the data, which signal to assert and at what time  the signal  should be made high or low, etc. Timing Diagrams, Pin Description 1.  Ã‚  CS, Chip Select: This is an active low pin and used to activate the ADC0804. 2.  Ã‚  RD, Read: This is an input pin and active low. After converting the analog data, the ADC stores the result in an internal register. This pin is used to get the data out of the ADC 0804 chip. When CS=0 high to low pulse is given to this pin, the digital output is shown on the pins D0-D7. 3.  Ã‚  WR, Write: This is an input pin and active low. This is used to instruct the ADC to start the conversion process. If CS=0 and WR makes a low to high transition, the ADC starts the conversion process. 4.  Ã‚  CLK IN, Clock IN: This is an input pin connected to an external clock source. 5.  Ã‚  INTR, Interrupt: This is an active low output pin. This pin goes low when the conversion is over. 6.   Vin+ : Analog Input . 7.   Vin- : Analog Input. Connected to ground. 8.  Ã‚  AGND: Analog Ground. 9.  Ã‚  Vref/2: This pin is used to set the reference voltage. If this is not connected the default reference voltage is 5V. In some application it is required to reduce the step size. This can be done by using this pin. 10.   DGND: Digital Ground. 11-18. Output Data Bits (D7-D0). 19. CLKR: Clock Reset. 20. Vcc: Positive Supply The above timing diagrams are from ADC0804 datasheet. The first diagram shows how to start a conversion. Also you can see which signals are to be asserted and at what time to start a conversion. So looking into the timing diagram  we note down the steps or say the order in which signals are to be asserted to start a conversion of ADC. As we have decided to make Chip select pin as low so we need not to bother about the CS signal in the  timing diagram. Below steps are for starting an ADC conversion. I am also including CS signal to give you a clear picture. While programming we will not use this signal. Make chip select (CS) signal low. Make write (WR) signal low. Make chip select (CS) high. Wait for INTR pin to go low (means conversion ends). Once the conversion in ADC is done, the data is available in the output latch of the ADC. Looking at the second diagram, which shows the  timing diagram  of  how to read  the converted value from the output latch of the ADC, data of the new conversion is only available for reading after ADC0804 made INTR pin low or say when the conversion is over. Below are the steps to read output from the ADC0804. Make chip select (CS) pin low. Make read (RD) signal low. Read the data from port where ADC is connected. Make read (RD) signal high. Make chip select (CS) high.
