Who is to blame in The rucible Essay Example For Students

Who is to blame in The ?rucible? Essay The Crucible was first produced in 1953 in 1952 in the middle of the McCarthy political witch hunts. Miller was trying to convey the parallel between the witch-hunts in Salem and the witch hunts for communists. The hysteria in Salem can be blamed on the individuals or the whole society. Although many individuals contributed to the hysteria the social conditions the characters, the young girls in particular, had to endure is also to blame. There are a number of characters to which some degree of blame could be attributed. One of these characters is Abigail. Abigail is the character who really gets the whole thing started; Uncle, we did dance We will write a custom essay on Who is to blame in The ?rucible? specifically for you for only $16.38 $13.9/page Order now She first openly admits to dancing in the woods and when the pressure is put on her she says that it was to blame on witchcraft. She uses the situation to her advantage and manages to get back at Goody Proctor who has blackened her name in the village. Although she is very manipulative in some ways she is a victim. She is treated as a child even though she is no longer innocent and virginal; Sweated like a stallion Abigail is very forward and speaks and acts like she is much older than she is. She is a young adult but nobody will treat her like one. Abigail had a relationship with Proctor, but still he calls her a child. Abigail seems to want to break free of the stereotype and this is what leads to hysteria. Abigail did not plan for the situation to get out of hand or lead to the death of innocent people, but she could not really stop it once the ball had started rolling. The accusations led to the hysteria to spiral out of control as more and more people were blamed. Society really is to blame though when it comes to Abigail as society put great pressure on her, which led her to try and break free of her stereotype. Another character that contributes to the hysteria is Parris. The way Parris approached his ministry led to problems. His selfish attitude contributes to the reaction of the girls. The way he runs the church leads to resentment and bad blood in the village. He should be preaching about God but instead he preaches about money. He is always thinking about himself too much and does not consider others; I cannot offer one proposition, but there be a howling riot of argument He may have been able to solve the problems but he couldnt be bothered with the hassle of it and would rather deal with his own problems. He is selfish and only really thinks about money. He thinks he deserves luxuries because he is a minister; Dont a minister deserve a house to live in His selfish attitude contributed to the hysteria in Salem. In some ways it is society to blame  for creating the conditions in which man like Parris, who is quite obviously not a very holy man, can lord it over others simply because he has the title of priest. John Proctor also contributes to the hysteria in Salem. His inability to control his lust contributes to events. His lust for Abigail led Abigail to believe that there could be a proper relationship between them; Ill not be comin for you no more He does try to make it clear to Abigail but he has already led her on too much. When Proctor calls her child it makes Abigail want to prove herself to him and she shows him how powerful she can really be. .u71c581b5ce82a033e630a0f4bd5e2c4a , .u71c581b5ce82a033e630a0f4bd5e2c4a .postImageUrl , .u71c581b5ce82a033e630a0f4bd5e2c4a .centered-text-area { min-height: 80px; position: relative; } .u71c581b5ce82a033e630a0f4bd5e2c4a , .u71c581b5ce82a033e630a0f4bd5e2c4a:hover , .u71c581b5ce82a033e630a0f4bd5e2c4a:visited , .u71c581b5ce82a033e630a0f4bd5e2c4a:active { border:0!important; } .u71c581b5ce82a033e630a0f4bd5e2c4a .clearfix:after { content: ""; display: table; clear: both; } .u71c581b5ce82a033e630a0f4bd5e2c4a { 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; } .u71c581b5ce82a033e630a0f4bd5e2c4a:active , .u71c581b5ce82a033e630a0f4bd5e2c4a:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u71c581b5ce82a033e630a0f4bd5e2c4a .centered-text-area { width: 100%; position: relative ; } .u71c581b5ce82a033e630a0f4bd5e2c4a .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u71c581b5ce82a033e630a0f4bd5e2c4a .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u71c581b5ce82a033e630a0f4bd5e2c4a .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; } .u71c581b5ce82a033e630a0f4bd5e2c4a:hover .ctaButton { background-color: #34495E!important; } .u71c581b5ce82a033e630a0f4bd5e2c4a .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u71c581b5ce82a033e630a0f4bd5e2c4a .u71c581b5ce82a033e630a0f4bd5e2c4a-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u71c581b5ce82a033e630a0f4bd5e2c4a:after { content: ""; display: block; clear: both; } READ: Social and Historical Background to 'Great Expectations' EssayIt seems as though if he had come forward earlier then he could have stopped what was happening. He would not admit to adultery because he did not want his name blackened in the village. Society is really to blame because it condemned sexual impropriety and it made him feel that he could not confess because it is a sin. Putnam is another one of the characters that contributes to the hysteria. He is the prime example of the land owning citizen. He seems to be motivated to make the problem worse. He is very selfish about his land and possessions; You load one oak of mine and youll fight to drag it home He is always fighting and bickering with other people about what belongs to him. As a prominent citizen he could have stopped the hysteria rather than fuelling it. He, instead of dealing with the problems he would rather try and gain more land by getting his daughter to cry rape. Society really is to blame for creating a man like Putnam who is given power through possession of money and use that power for greed. In fact Proctor indicates how the village seems based on money not equality. There is also a collective blame. All the characters build up to create a society, which is prone to this type of situation. The land disputes add to the problems. No single character tries to whole heartedly to solve the crisis because of fear of damaging their own reputation. The way women and children are treated also contributes to the problem. Many of the young women are treated like children and want to demolish the stereotype. There are certain attitudes towards pleasure which means that many of the girls would have had a starved imagination and social life which would have made the witch hunts seem exciting and appealing. The girls were rarely made centre of attention so this sudden interest shown towards them would have also been appealing. It would have seemed ridiculous to them to remove themselves for the spotlight, which they rarely have upon them. Overall it was the whole of society to blame rather than the individual characters. As the village was in the middle of  nowhere there was no escape. This made the situation more intense because everyone was trapped. These external influences slightly contribute to the atmosphere. There are many parallels between the society in Salem and the communist witch hunts. Both conditions are similar; in both cases people are being persecuted without a proper trial or any evidence. Both societies have resentments and jealousies. Miller uses the book to create an absurd situation to mock the McCarthy witch-hunts. It is the individual characters that contribute to the chaos. All of the characters build up to create a society prone to this type of situation.

Living Resources of the Ocean

Living Resources of the Ocean Introduction The ocean is among the most important natural resources bestowed upon mankind. It has extensive benefits to human life and it provides a wonderful ecosystem in which other organisms live. The following are some examples of the benefits that the ocean has on human life (2). The ocean is extensively used for transportation of bulky goods over long distances. It is also a very valuable source of a number of minerals and crude oil. Most of these minerals are found in deep sea.Advertising We will write a custom essay sample on Living Resources of the Ocean specifically for you for only $16.05 $11/page Learn More Examples of these oceanic minerals include cobalt, salt, iron, copper, manganese etc. The ocean is also a valuable recreation site for human beings. It provides a serene environment that acts as an attraction to people on holidays seeking relaxation. The ocean is also a source of organisms with useful medical value. It also regulates the leve l of greenhouse gases in the atmosphere by taking atmospheric carbon dioxide and giving out oxygen. This is a very important input in the efforts towards reduction of the levels of global warming. Lastly, the ocean is a very important source of biodiversity (1). It provides organisms that have great value to human life. The most commendable among the benefits of marine life to human life are the fact that marine life can act as food and the fact that some oceanic organisms have medicinal value. Living resources of the ocean The marine habitat harbors a large percentage of the earth’s cumulative population of plants and animals. Over one million animal species and plant species have already been discovered and scientists have estimated that an extra nine million species are still living in the marine biome without human discovery. Garrison, Tom. Essentials of Oceanography. Wadsworth Publishing. Resenick, John. Marine Biology. Reston Publishing Company This means that, of all p lant and animal population living in the ocean we only know 10%. Thus if the scientists are right, there is a lot of plant and animal species in the oceans that could have more value than just medicines and food. Let us explore the marine animals that have already been discovered.Advertising Looking for essay on environmental studies? Let's see if we can help you! Get your first paper with 15% OFF Learn More Fish The ocean has been the leading source of fish for ages. Humans have used the ocean for a very long time as their source of fish for food. The fact that the ocean is full of a myriad species of fish is thus obvious. Specific examples of marine fish and their adaptations include the black swallower which is able to triple the size of its stomach in order to prey on other fish that are bigger that it is. Another example is the tripod fish which derives its name from its exceptionally long caudal and pelvic fins. Fish also have other adaptations for mari ne life. Virtually all fish have streamlined bodies for ease of locomotion (1). All fish have their blood pumped from the heart to the gills from where it is supplied to other body parts. Thus fish are, in this way adapted to survive in deep water by taking in oxygen from the water through their gills. Fish have also been able to survive in oceans due to the constant availability of their chief food: the planktons. These are small fish that are preyed upon by virtually every marine organism. Thus marine fish can never be starved. A discussion about the types of marine fish would be incomplete without the mention of sharks. Sharks are widely known for their huge bodies. They feed on other animals and thus they are carnivores. Their common diets include lobsters, crabs, bony fishes, worms and mollusks. The choice of what to eat is normally determined by the availability of the latter. Thus pelagic sharks normally feed on squid. Sharks will therefore eat dead fish at the ocean floor. G arrison, Tom. Essentials of Oceanography. Wadsworth Publishing. Tiger sharks are believed to be able to eat anything. Most sharks spend almost all their time swimming in order to allow respiration to freely take place. However, other sharks are normally found in ocean floors where they carry out their respiration normally (1). Marine Mammals Marine life is also composed of a number of mammals. Just like other marine life forms, mammals are adapted to cope with the harsh living conditions that are characteristic of marine life. For example, they normally have a thick layer of fat under their skins to help them insulate their bodies from excessive heat loss. This is because some regions of the experience extremely cold temperatures.Advertising We will write a custom essay sample on Living Resources of the Ocean specifically for you for only $16.05 $11/page Learn More Contrarily, sea otters, an example of ocean mammals, have dense fur instead of blubber that s erves the purpose of insulating them from the extremely cold temperatures of the ocean. These adaptations against heat loss are necessitated by the fact that marine mammals are similar to terrestrial mammals in terms of their warm bloodedness. They are thus forced to develop these adaptations in a bid to keep their temperatures above ocean temperatures. Other examples of marine mammals include seals, whales, sea cows, dugongs and manatees. Other adaptations of mammals to heat insulation include a large internal volume and reduced surface area. Their blood is also controlled to ensure that only a negligible amount comes close to cold water. They also have other adaptations to marine life apart from heat insulation mechanisms. Such adaptations include ability to expel air from lungs as they dive deep in the ocean (Garrison 1). This enables them to avoid excess intake of nitrogen. Garrison, Tom. Essentials of Oceanography. Wadsworth Publishing. They also have slower heartbeats, high am ount of hemoglobin in blood and strategic blood flow. Both fish and marine mammals have streamlined bodies but while marine mammals are capable of swimming both horizontally and vertically, most fish are only able to swim horizontally. This is due to difference in the adaptation of their tails. Mammals are horizontal while those of a majority of fish have horizontal orientation. Fish and most mammals have streamlined bodies which enhances their mobility in water. The few mammals which do not have streamlined bodies have other special adaptations that enable them to survive in the ocean. These special adaptations include camouflage or body armors that protect them from sea carnivores (1).Advertising Looking for essay on environmental studies? Let's see if we can help you! Get your first paper with 15% OFF Learn More Benthic life forms Benthic is a term used to describe the area of the ocean that lies below the pelagic zone. It is not the last zone in terms of depth but in spite of this fact, it is normally referred to as the sea bed. The deepest zone of the ocean is known as the abyssal zone. The benthic zone is characterized by extremely cold water since sunlight does not penetrate such depths. Organisms that live in the benthic zone are mainly fungi, bacteria, fish, worms and sponges. These benthic forms survive in the harsh conditions of this zone because they normally have adaptations for resisting cold temperatures and also because the benthic zone is rich in nutrients. Also evident among benthic life forms are sea stars which are normally carnivorous (1). Other marine life forms Other marine life forms include animals that have impenetrable shells that protect them from being preyed by other animals in the ocean. Garrison, Tom. Essentials of Oceanography. Wadsworth Publishing. An example of such animals is the chitons which live exclusively in the ocean. The feature that distinctively identifies them is the overlapping plates at the back of the animal . The plates are eight in number and they enhance the physical morphology of the animal for protection. Such organisms normally have underdeveloped organs for compatibility of their bodies with their shells (4). Their adaptations to marine life have made them thrive in this carnivorous environment for many years. This is in spite of the fact that they are preyed by sharks. Preservation of marine biome A lot needs to be done to reduce the rate of extinction of marine life. Human activities like fishing, industrialization (pollution), reconstruction, experimentation, transportation etc. have had a persistent negative effect on marine life. A considerably large number of fish die every year due to the pollution caused by the disposal of industrial effluents in to the ocean. In other areas people have overfished the oceans , catching juvenile fish and thus limiting the growth of fish population. Fishermen have also continually used wrong fishing methods that continue to be a threat to the growth of biodiversity (3). For example, some fishermen may utilize fishing methods which make them catch unwanted species of fish and thus contributing to the inability of certain species of fish to multiply. It is our responsibility to strive to conserve marine life. For instance, when planning reconstruction of intertidal oceanic zones, we should first of all analyze the effect that our projects are likely to have on marine life and carry out the necessary steps to reduce them. Berta, Annalisa. Marine Mammals. McMillan Publishing. Littler, Mark and Littler, Diane. â€Å"The Evolution of Thallus Form and Survival Strategies in Benthic Marine Microalgae For instance, before reconstruction, artificial waters could be made in the ocean shores to preserve corals and fish so that they can be protected from the effect s of the reconstruction process. Organizations should ensure that they practice Corporate Social Responsibility by contributing philanthropically to projects involving conservation of marine habitat. Governments should also ensure that regulations are laid down that support the fight against extinction of marine life forms (1). They should thus discourage industrial pollution by all means and ensure that other factors that negatively affect marine life are controlled. Conclusion Marine life was once thought to be so dynamic that it was under no threat of extinction. Contemporary research has shown that marine population is drastically reducing due to uncontrolled exploitation (1). The worrying bit is that the recovery rate of marine life after exploitation is very slow as compared to the growth rates before exploitation. Marine mammals are particularly endangered. This is because they must surface in order to breathe before going back underwater. This makes them easy targets for hum an capturing. With these worrying trends in the population of marine life, we are obliged to take preventive measures to ensure that our negative effects on marine life are minimized. We owe our future generations the responsibility of preserving biodiversity for them and thus we should do our best in ensuring that the best measures towards preserving biodiversity are implemented.

What evidence that marilyn monroe did not kill herself Research Paper

What evidence that marilyn monroe did not kill herself - Research Paper Example In this paper, I would look into every aspect and clue which could take us to a point, whether Marilyn died accidently, was it an intentional suicide attempt? Or was it a planned plot against her? Marilyn’s death is an unsolved mystery and it is still the most debatable conspiracy theory. She died on August 5th, 1962 at the age of 36 and was found dead in her bedroom by her psychoanalyst consultant doctor, Ralph. S. Greenson who was being called by her caretaker Eunice Murray. She got married thrice in her life but wasn’t able to keep her relations for long. She first got married to James Dougherty in 1942 which lasted for four years only; second marriage with Joe DiMaggio, the famous football player lasted for nine months and her third marriage with a play writer Arthur Miller ended up in five years. There are several reasons for which this death is still not digestible for many people. Marilyn was addicted to sleeping pills and was mentally disturbed and therefore she had two consultant doctors, Doctor Ralph Greenson and Doctor Hyman Engelberg. Her death report showed that she died of acute barbiturate poisoning which was either taken purposely for a suicide attempt or was intentionally given to murder her for a reason. However no murder charges were made. Dr. Thomas Noguchi look at this death as an uncertain suicide because as a pathologist, he did not find any residue in Marilyn stomach if such high dose would have been taken orally, there had to be a residue in her stomach or any evidence in blood. Moreover her toxicology report showed that her organs were completely damaged and there was a presence of Nembutal and chloral hydrate in extreme level which could kill ten people. There were no signs of intravenous injections however suppository could have been used to transfer t his amount in her body (Morgolis,

Situation-Background-Assessment-Recommendation (SBAR) - Coursework Example This paper illustrates that P.J is a young man living with his father in the countryside. His two brothers are living and working in New York. According to P.J, his living situation has not been very pleasant as stated in the â€Å"Health History and Screening†. He lacks company while at home and his father is alcoholic. His mother died when he was only 13 years of age. Two years later after this death, his younger sister passed away. All the above-stated health problems in the â€Å"situation† section have different genesis in origin and time. The problem of duodenal ulcers began in the year 2007 when the client was still in high school. The stomach problem started as a mild upset that later turned into the ulcer. He was put on medication for close to two weeks. The situation slightly improved but he still occasionally feels the ulcers to date. Food intolerance and allergy began in at the early stages of his childhood. The client cannot even remember when and how this problem started. He cannot comfortably eat red meat and milk since they give him severe stomach ache and nausea. When he was diagnosed with ulcers, he became intolerant to more foods such as beans, tea, oily food, green vegetables, sugary foods, spices and others that he could not recall. However, he has learned to assimilate some of these foods with time but the childhood food intolerance not gone away. Besides, he has not made any attempt to find the cure for the intolerance. He believes the intolerance helps him cut the cost of living by eating only a few simple meals. The problem of depression began when P.J was still in high school. As a child, he never knew what stress was, even though he grew up in a family of a humble background. His mother had just died when he was taken to a boarding school far away from home. It was while in school that he started to experience frequent stress and anxiety that led to a long-term depression. The urinary system problem, though not very seve re, started at the age of about 8 years. He could feel a burning sensation while urinating with a thin stream. However, this condition was not frequently felt.

Fuzzy Logic Control Implementation On Pic Microcontroller

Fuzzy Logic Control Implementation On Pic Microcontroller Conventional PID controllers were used as a control strategy for various industrial processes from many years due to their simplicity in operation. They used mathematical models to control the plant for different process control applications. Fuzzy logic based control systems were introduced by Lotfi Zadeh to optimize the process control parameters in better way. In this paper, we have implemented a DC motor control strategy with the help of PID controller.Then we will optimize it with the help of fuzzy logic controller. The fuzzy logic control strategy shows the improvement in various control parameters like maximum overshoot, settling time for the DC motor control as compared with PID control strategy. This shows the superiority of fuzzy logic controller over proportional integral derivative controller. I. INTRODUCTION PID (proportional integral derivative) control is one of the earlier control strategies. Its early implementation was in pneumatic devices, followed by vacuum and solid state analog electronics, before arriving at todays digital implementation of microprocessors. It has a simple control structure which was understood by plant operators and which they found relatively easy to tune. Since many control systems using PID control have proved satisfactory, it still has a wide range of applications in industrial control. PID control has been an active research topic for many years. Since many process plants controlled by PID controllers have similar dynamics it has been found possible to set satisfactory controller parameters from less plant information than a complete mathematical model. Fuzzy logic is a method of rule-based decision making used for expert systems and process control that emulates the rule-of-thumb thought process used by human beings. Due to these properties, fuzzy logic can be used to control a process that a human can control manually with expertise gained from experience. The linguistic control rules that a human expert can describe in an intuitive and general manner can be directly translated to a rule base for a fuzzy logic controller. In this paper DC motor is first tuned using fuzzy logic controller and then we will be using fuzzy logic controller to improve the various process parameters follow. II. PROPORTIONAL INTEGRAL DERIVATIVE CONTROLLER The PID controller is the most common form of feedback. It was an essential element of early governors and it became the standard tool when process control emerged in the 1940s. In process control, more than 95% of the control loops are of PID type, most loops are actually PI control. PID controllers are today found in all areas where control is used. The controllers come in many different forms. There are standalone systems in boxes for one or a few loops, which are manufactured by the hundred thousands yearly. PID control is an important ingredient of a distributed control system. The controllers are also embedded in many special purpose control systems. PID control is often combined with logic, sequential functions, selectors, and simple function blocks to build the complicated automation systems used for energy production, transportation, and manufacturing. Many sophisticated control strategies, such as model predictive control, are also organized hierarchically. PID control is u sed at the lowest level; the multivariable controller gives the setpoints to the controllers at the lower level. It is an important component in every control engineers tool box. PID controllers have survived many changes in technology, from mechanics and pneumatics to microprocessors via electronic tubes, transistors, integrated circuits. The microprocessor has had a dramatic influence on the PID controller. Practically all PID controllers made today are based on microprocessors. This has given opportunities to provide additional features like automatic tuning, gain scheduling, and continuous adaptation. Controllers are designed to eliminate the need for continuous operator attention. Cruise control in a car and a house thermostat are common examples of how controllers are used to automatically adjust some variable to hold the measurement (or process variable) at the set-point. The set-point is where you would like the measurement to be. Error is defined as the difference between set-point and measurement. error = set-point measurement The variable being adjusted is called the manipulated variable which usually is equal to the output of the controller. The output of PID controllers will change in response to a change in measurement or set-point. Manufacturers of PID controllers use different names to identify the three modes. These equations show the relationships: P (Proportional) = 100/gain I (Integral) = 1/reset (units of time) D (Derivative) = rate = pre-act (units of time) Depending on the manufacturer, integral or reset action is set in either time/repeat or repeat/time. One is just the reciprocal of the other. Note that manufacturers are not consistent and often use reset in units of time/repeat or integral in units of repeats/time. Derivative and rate are the same. Choosing the proper values for P, I, and D is known as PID Tuning. A feedback control system measures the output variable and sends the control signal to the controller. The controller compares the value of the output signal with a reference value and gives the control signal to the final control element. The equation of ideal PID controller is $$ C(s) = K_{p} + frac {K_{i}} {s} + K_{d}s = frac{K_{d}s^2 + K_{p}s + K_{i}} {s} $$ III. FUZZY LOGIC CONTROLLER Fuzzy logic is a method of rule-based decision making used for expert systems and process control that emulates the rule-of-thumb thought process used by human beings. The basis of fuzzy logic is fuzzy set theory which was developed by Lotfi Zadeh in the 1960s. Fuzzy set theory differs from traditional Boolean (or two-valued) set theory in that partial membership in a set is allowed. Traditional Boolean set theory is two-valued in the sense that a member belongs to a set or does not and is represented by 1 or 0, respectively. Fuzzy set theory allows for partial membership, or a degree of membership, which might be any value along the continuum of 0 to 1. A linguistic term can be defined quantitatively by a type of fuzzy set known as a membership function. The membership function specifically defines degrees of membership based on a property such as temperature or pressure. With membership functions defined for controller or expert system inputs and outputs, the formulation of a rule base of IF-THEN type conditional rules is done. Such a rule base and the corresponding membership functions are employed to analyze controller inputs and determine controller outputs by the process of fuzzy logic inference. By defining such a fuzzy controller, process control can be implemented quickly and easily. Many such systems are difficult or impossible to model mathematically, which is required for the design of most traditional control algorithms. In addition, many processes that might or might not be modeled mathematically are too complex or nonlinear to be controlled with traditional strategies. However, if a control strategy can be described qualitatively by an expert, fuzzy logic can be used to define a controller that emulates the heuristic rule-of-thumb strategies of the expert. Therefore, fuzzy logic can be used to control a process that a human can control manually with expertise gained from experience. The linguistic control rules that a human expert can describe in an intuitive and general manner can be directly translated to a rule base for a fuzzy logic controller. IV. PROBLEM FORMULATION A DC motor is taken as a case study and the control is achieved using conventional PID controller and intelligent fuzzy logic based controller. The comparison of both the controller performance is analyzed.After analyzing,implement it on microcontrollers. V. DC MOTOR CONTROL USING FUZZY LOGIC CONTROLLER In classical control techniques PID controller was used as a standard control structure. Due to nonlinearities in the process the performance of the industrial machinery is greatly distorted and the efficiency is reduced. The new technique which uses fuzzy and PID controllers is considered as the extension of the conventional technique, because it preserves the linear structure of PID controller. These controllers are designed using the basic principle of fuzzy logic control to obtain a new controller that possesses analytical formulas similar to digital PID controllers. Fuzzy PID controllers have variable control gains in their linear structure. These variable gains are nonlinear function of the errors and changing rates of error signals. These variable gains help in improving the overall performance due to their characteristics features like self-tuned mechanism which can adapt to rapid changes of the errors and rate of change of error caused by time delay effects, nonlinearities and uncertainties of the process. VII. CONCLUSION In this paper a DC motor is controlled using fuzzy logic and PID controller. A mathematical model to control the DC motor is developed and the motor is controlled using conventional PID controller. The simulation results so obtained show that the PID controller gives high overshoot and settling time. Hence, fuzzy logic controller design was proposed and implemented using the principles of artificial intelligence. The fuzzy logic control will be implemented and the response will be compared with conventional PID controller. The fuzzy logic control shows a better control of motor parameters as compared with the conventional PID controller VII.

Women in Bamboozled Essay -- essays research papers

Our team chose to focus on representations of women in Spike Lee’s latest joint, â€Å"Bamboozled†. This theme was attractive to us because we felt the filmmaker had a powerful message to send his audience after viewing the trailer in class. Despite the fact that there is only one woman in a starring role, a multitude of specific and acute ideas are presented by Spike Lee through the film. We were also eager to take advantage of the opportunity to apply what we have learned in class to the thought-provoking and controversial nature of his work.   Ã‚  Ã‚  Ã‚  Ã‚  When reflecting upon representations of women, we felt that a continuous motif of women as puppets is present. The lead female character, Sloan Hopkins, is played by Jada Pinkett Smith. She comes across as being under Pierre Delacroix, or his puppet, from her first appearance in the film. The opening scene of the movie emphasizes this as he is yelling at her for not informing him of a staff meeting. Sloan continually apologizes but, not knowing about the meeting, has no reason to do so. Regardless of this fact, she is put down and silenced by Delacroix. He dismisses everything she says and acts as the voice of authority with no consideration of the actual circumstances. She is merely his puppet who has failed. When Delacroix comes up with the â€Å"Mantan Show† idea, Sloan feels strongly against it. However, she is the one who has to research and come up with historical portfolios for the show. She tries to educat...

King David- A short outline essay of his life Essay

â€Å"A man after God’s own heart† is what David is called in I Samuel 13:14. So, it is very helpful to discover that he is not sinless but a man of great passions and driven by great desires. He has a violent temper and is a vicious, cruel killer. However, when the Lord puts the finger on him, he is also completely repentant. He has the whole spectrum of emotions that you and I have, yet God calls him a â€Å"man after His own heart,† because, even though he fails God many times, he loves God wholeheartedly. David’s Rise: God Chooses David to be King- King Saul, though a talented king, had stopped obeying God early in his career, and had begun turning selfish and evil. So God told the prophet Samuel he would remove Saul from being king, and replace him with â€Å"a man after his own heart†. The Battle with Goliath- David approached Goliath on the run, sling in hand. His first shot penetrated the giant’s forehead, and he fell facedown, dead. Saul Turns on David- Saul threw his spear, and David narrowly dodged the spear. Fearing for his life, David finally decides he isn’t safe and left town that night. David in Exile- David wandered the wilderness, living in caves. Many other fugitives sought him out, and soon he had a community of 400 families in his care. David Spares King Saul- David passed up a chanced to kill Saul, out of respect for the LORD, and he displayed the hem of Saul’s robe as evidence. He furthermore promised he would never harm the king the LORD had chosen. King Saul Dies in Battle- Saul was mortally wounded, and fearing that hisenemies would capture and torture him, he takes his own life. David, King of Judah- under David’s powerful leadership, Judah grew stronger and stronger. Under Ishbosheth’s incompetence, Israel grew weaker and weaker. David, King of Israel- David’s military prowess became legendary. He converted many nearby nations from aggressors into subdued enemies. By the end of his life, his empire was so powerful that there was peace, and his son Solomon never had to fight a war. The Ark of the Covenant- Instead of carrying the Ark as prescribed; they followed the example of the Philistines, placing it on a cart. Then at one climactic moment, the oxen stumbled, the cart was upset, and the Ark was in danger of falling to the ground. One of the Levites, named Uzzah, reached out to steady the Ark, ignoring the prohibition against touching it. For this offense, the LORD instantly struck him dead. Preparations for the Temple -The LORD had different plans. He told Nathan to go back to David and tell him he was not the one to build a temple. Instead, after David’s death his son would be king in his place, and he would build the temple. David’s Decline: Scandal- David sends one of his commanders to die in battle after falling for his wife and getting her pregnant. Later this son dies and God continue to curse him by turning his family against him. Amnon’s Crime- The prince rapes his sister and King David handling of this crime shows his loss of good judgment since his own similar crime. Absalom’s Crime- Another one of David’s Sons and the full brother of Tamar, swears revenge and ends up having his brother killed and then becomes exiled to prevent his own death. Absalom’s Rebellion- Almost as soon as Absalom returned to Jerusalem, he began conspiring to overthrow his father King David and take his throne. Absalom died under Joab’s sword. Sheba’s Rebellion- One of the leaders in the bickering over the land left by king Absalom, a man named Sheba, declared himself king of Israel, exclusive of Judah. He raised an army, and civil war began once again. Adonijah’s Rebellion- When King David was old; he lost awareness of much that happened around him. God had chosen Solomon, and David had privately promised that Solomon would succeed him as king. But in his feeble condition he was losing control of his kingdom, and his ability to control who succeeded him was in doubt. At this moment David’s son Adonijah decided to make himself king. When Bathsheba, Solomon’s mother heard this she went to David and reminded him that God had chosen Solomon as the new king of Israel. David finally had a clear moment and made sure that Solomon took over the Kingdom. As Solomon took over as king he sent Adonijah home with the warning that if he ever showed the slightest sign of treason again, he would die. Later, Adonijah schemed to obtain one of now-dead David’s assistant girls for his wife. This seemed innocent enough, but it reminded Solomon vividly of similar schemes Adonijah’s brother Absalom had used in his treasonous bid for the throne. Solomon interpreted this as the first step in Adonijah’s renewed effort to overthrow Solomon, and ordered him put to death, along with some of the top people in Adonijah’s original conspiracy.

Red Dragon essays

Red Dragon essays I chose the book Red Dragon because I really enjoy all the movies that have been made about Hannibal Lecter, The Silence of the Lambs, Hannibal and not to mention Red Dragon. This 351 pages long book was written by the author Thomas Harris in 1981 but he was also the author of another of my favorites Silence of the Lambs. There have been made motion pictures after both those books. Thomas, a native of Mississippi, began his writing career covering crime in the United States and Mexico, and was a reporter and editor for the Associated Press in New York City. His first novel, Black Sunday, was published in 1975, followed by Red Dragon in 1981, The Silence of the Lambs in 1988 and Hannibal in 1999. The story is about a former detective, Will Graham.

Game Play Project Essay Example | Topics and Well Written Essays - 500 words

Game Play Project - Essay Example Markers or crayons, yarn, buttons, and glue-sticks are materials that are cheap and are a great way to decorate the puppets without creating a mess. There are many available designs that workers can teach the young patients which can be viewed on Enhantedlearning.com. After designing the puppets, the worker and the children can develop a dialogue about their specific puppet such as their name and basic characteristics. Workers can prompt the children with questions such as â€Å"What’s your puppets name? What’s the puppet’s favorite food, activity, etc? Does the puppet have any brothers and sisters?† Finally, the children can create a story whether through improvisation or writing out a scene and act out the story using their puppets. This activity does not have any major safety risks that need to be addressed. As long as the adult/worker has prepared the yarn before hand, there is no need to bring scissors or any other risky material into the patient†™s environment. The puppet activity can be modified for children as young as four or five and as old as nine or ten.

Classroom observation Essay Example | Topics and Well Written Essays - 250 words

Classroom observation - Essay Example Classroom observations raise the level of teachers’ consciousness and anxiety no matter how casually a director may perform them, because the teachers know that their capabilities are being assessed and their performance is being critically analyzed. The acquired consciousness is quite likely to sap a teacher’s ability to demonstrate the best he/she has. On the other hand, owing to the great significance of classroom observations in the improvement strategies of the educational setup, their importance can not be denied and they can not altogether be eliminated. Therefore, there is need to devise ways in which classroom observations can be conducted with least inconvenience to the teachers. (Monarch) identifies ways in which the activity can be performed in the most meaningful and supportive manner. Classroom observations can be improved by pre-observation discussions, and providing the teacher with an opportunity to express his/her concerns about the class. It is advisa ble for the teacher and director to mutually select a focus of observation prior to conducting it. Data can be collected on pre-formatted layouts. Finally, feedback strategies should be well managed and the teacher’s perspective should be appreciated (Murdoch 2).
