King Lear Essays (1437 words) - King Lear, Fool, Cordelia, Edmund

King Lear King Lear is a play written by William Shakespeare that focuses on the relationships of many characters, some good, some evil. This is a great tragedy that is full of injustice at the beginning and the restoring of justice towards the end. The good are misjudged as evil and the evil are accepted as good. It is not until the end of the play that the righteous people are recognized as such. There is great treachery and deceit involved in the hierarchy of English rule. The great mistake in this play was made by Lear when he decided to divide up his kingdom to his three daughters. In order to determine which share each should get, he had each of his daughters give testimonies of love for him. Cordelia, the youngest, refused to go overboard with her statement. When asked for her testimony, she simply replied, "Unhappy that I am, I cannot heave my heart into my mouth. I love your Majesty according to my bond, no more no less."(I,i, ln 91-93) Lear becomes enraged and casts her off saying, "Here I disclaim all my paternal care, propinquity and property of blood, and as a stranger to my heart and me hold this from thee for ever."(I,i, ln 113-116). Some think that Cordelia was prideful, or even a fool in her response, but I believe she was simply being honest and true. Another mistake that was made in the course of the play was by the Earl of Gloucester. After being tricked by his bastard son, Edmund, into believing that his other son, Edgar, was plotting to kill him, he put all his faith in Edmund, which would eventually lead to his demise. Besides believing that Cordelia was being true and honest to her father, I think that Lear and the Earl of Gloucester were fools, regarding the banishments of their righteous children. After reading this play, I found it hard to believe that Cordelia was being anything but true in her simple proclamation of love for her father. I can't believe that Shakespeare was trying to portray her as a spoiled, prideful child. I do not believe she was foolish in her decision to restrain from trying to persuade him into giving her a larger portion of his kingdom. I think it was apparent early that Cordelia was struggling with what she was going to say to her father. In her asides she says, "What shall Cordelia speak? Love, and be silent"(I,i, ln 62), and after Regan spoke, "Then poor Cordelia; And yet not so, since I am sure my love's more ponderous than my tongue."(I,i, ln 76-78). It is obvious that she loves her father, but she can't express it the way in which Lear wants her to. Because of this, she is disowned and sent away to France. The King even refers to her as, "Unfriended, new adopted to our hate, dow'red with our curse, and strangered with our oath."(I,i, ln 203-204). Cordelia's love for her father was shown further when she received the letters concerning Lear's mental state after being mistreated by his two other daughters. It was said that, "now and then an ample tear trilled down her delicate cheek."(IV,iii, ln 12-13). Cordelia then orders for some of the French soldiers to bring Lear to her so that she can look after him before the war between Britain and the French soldiers begins. Her love was further displayed when she says, "But love, dear love, and our aged father's right. Soon may I hear and see him!"(IV,iv, ln 28-29). Because of all of this, I firmly believe that Cordelia truly loved her father and was only being honest when she refused to profess her love for him in order to rule a portion of Britain. Besides believing that Cordelia was true in her response, I also think that Lear was acting as a fool when he disowned his only loving daughter. He made a monumental mistake when he handed over British rule to his two evil daughters, Regan and Goneril. This is what eventually led to his mental breakdown and the deaths of many of the heads of Britain. If he had only chose to keep control

buy custom Programmable Logic Controls essay History of Programmable Logic Controls With emergence of new technologies, control engineering has undergone drastic changes. In the ancient days, only human beings could control a system. The 19th and 20th century witnessed great deal of advancement in technology. Electricity based on relays has been adopted for control systems. More recently the development of Programmable Logic Control (PLC) has added up to the advancing manufacturing controls. PLC has been widely used in industrial automation. The advent helps control and regulates sequence in any production operations. Notably, most production process undergo a fixed a logical steps. PLC has gained popularity in most industries and is expected to become predominant even in the future. During early days of its inception, PLC was hard wired by use of logical units, timers and electronic relays. It restricted production time and it was hard for products to be changed. The system was not effective, and this forced engineers to invent a flexible PLCs system. The pursuit for an effective control system started in 1970s. This was facilitated by the advent of mini-computers which allowed easy change of input-output features of a manufacturing process. In 1980s, fast and reliable microprocessors came into being. In effect, this facilitated the emergence of the current PLCs. The instrument is robust and serve many functions. The system is available in small, medium and large sizes (Vernon 2010). Units of a Programmable Logic Control PLC has four distinct functional units. The system has a Programme Memory where the instructions and procedures for the logical steps of a manufacturing process are stored. The system has a Data Memory which carries interlocks, status of the switches and values of data. The output devices comprises of hardware and software drivers which are commonly used by the industrial process actuators which may include motors, valves and solenoid. The input device is another unit that has hardware and software drivers such as proximity detectors, switch status sensors and interlock setting. Other than the above mentioned units, Programmable Logic Control has a superior programming unit. In most cases, a PC may be connected to PLC to make a programming unit (Lewis 2008). The programming unit performs very crucial role during automated manufacturing process. It is used for building, testing and editing logical steps that to be followed during the manufacturing operations. PLCs are programmed diffe rently by different manufacturers using their own standards and definitions. The most programming languages used include Sequential Function Chart, IIEC 61131-3 standard and Function Block Diagrams. However, Ladder Logic is a programming language that has been well established and wiidely used by PLC programmers (Lewis 2008). Functions of PLC System tools The basic function of Programmable Logic System is to admit information from switches and sensors to control machines in a manufacturing process. It electronically rewires the established control panel thus facilitating relay of information. In the recent times, PLC roles have extended beyond mere relay of information in system circuits to food processing and environment control. The PLC communication tools, processing power and information treatment process have replaced desktop computer. Advantages of using PLC PLC has been widely used in most manufacturing industries because of its numerous advantages. Firstly, PLC is cost-effective for controlling sophisticated manufacturing processes and systems. Secondly, it is flexible hence can be used to control other complex systems easily. Thirdly, PLC has high computational abilities thus allowing a classy control of the manufacturing operations. PLC allows trouble shooting thus making programming easier. Due its reliable components, the system can operate for a long time without failure. Disadvantages of Programming Logic Controls The system is expensive to installed hence small companies would be able not utilize the invention. It requires technical expertise which might be lacking in most organizations. Buy custom Programmable Logic Controls essay
