Chinas Support for North Vietnam in the Vietnam War

Introduction One of the major wars waged after the Second World War was the Vietnam War (1965-1968). The two major antagonists in this war were China which backed North Vietnam and the US which backed South Vietnam. This war was in actual sense a front from which an ideological war between China and America was waged.Advertising We will write a custom research paper sample on China’s Support for North Vietnam in the Vietnam War specifically for you for only $16.05 $11/page Learn More China was keen on spreading communism while the US was equally keen on advancing capitalism or at least curbing the spread of communism. The then US president Lyndon Johnson adopted a policy favorable to South Vietnam. Therefore, the US extended its commitment to preserve the independence of South Vietnam from the communist threat that North Vietnam posed. On the other hand, there existed a close relationship between North Vietnam and China. Evidence of this is presen t in the assurance from Chinese Leader Mao Zedong to the North Vietnamese that â€Å"your business is my business; my business is your business, we together will unconditionally fight America† (Bradley 9). China therefore vowed to support the north to whatever extents were needed. This paper shall analyze the specific manners in which China supported Vietnam in the course of the Vietnam conflict. Reasons for Chinese Involvement and Support A major result of World War two was the emergence of two Super Powers, The USA and the Soviet Union, both of which favored different political ideologies. While the US favored capitalism, the Soviet Union was pro communism and aimed to spread this ideology to its spheres of influence. One of the biggest allies of the Soviet Union was China which advocated for an even more radical implementation of communism. China was committed to the idea of a communism which emphasized violent revolution and Vietnam presented a perfect ground from which C hina could propagate its ideology. In addition to this, China was even more determined that Moscow to spread the communism ideology everywhere. Aiding North Vietnam presented an immediate means through which China could oppose the US and as such, undermine capitalism. Vietnam was the arena for China’s support for â€Å"wars of national liberation† and china encouraged North Vietnam to take on an aggressive course in the fight to unify the north and the south. As of the time of the war, the capital city of South Vietnam was Saigon while that of the North was Hanoi. US defense of South Vietnam was an expression of greater commitment to battle against Communism in Southeast Asia. Another reason for the increased Chinese support of Vietnam was the deteriorating relationship between the Soviet Union and China. These Sino-Soviet tensions were brought about by ideological and political issues between the two communist states. This split between the Soviets and Chinese resulte d in public criticism of each other’s policy and each party aimed to establish itself as the major communist power. For China, supporting Vietnam would reinforce its power and influence among the communist countries.Advertising Looking for research paper on asian? Let's see if we can help you!

This opposition was as a result of the realities from the First Indochina War which ended in 1954 with a decisive victory for Hanoi against the French. Following this victory, China and the Soviet Union had failed to support North Vietnam in their ambition to reunify Vietnam under communist rule. This lack of support had resulted in North Vietnam failing in its unification attempts and Hanoi viewed this as a betrayal by their Communist comrades. With this historical backdrop, China was keen to ensure that North Vietnam did not lose out again since a loss would destroy Hanoi’s trust in China. Ways in which China Supported North Vietnam Even before the Vietnam War began, China had made it clear to the US that any military action against Hanoi would be considered as action against China and as such, China would give military support to North Vietnam. Actual Chinese support of North Vietnam began following the Gulf of Tonkin incident in which a US navy ship was engaged by North Vietnamese boats resulting in a sea battle. Following this incident, America undertook reprisal air strikes against North Vietnam. The air strike code-named â€Å"Rolling Thunder† commenced on March 2, 1965 and its aim was to pressure Hanoi and Beijing into stopping their aggression against Saigon. In response to this reprisal Beijing ordered Chinese air and naval units which were to the south of China to be ready for combat. In addition to this, a number of air divisions and anti-aircraft artil lery divisions were deployed near the North Vietnam border. Dinglie and Kongjun document that China â€Å"sent some MIG-15 and MIG-17 jets to Hanoi to deter further U.S. escalation of the war†(385). Weaponry plays a crucial role in all battle and the availability of surplus quality weapons often dictate which side emerges victorious. Under the terms of the 1954 Geneva Agreements, Hanoi was forbidden from increasing its military force. This meant that Hanoi had a limited supply of military forces and the international community was unwilling to supply Hanoi with military equipment. As a result of this, North Vietnam was ill equipped for battle against the American backed South which had superior weaponry. The Chinese helped to equal the battle ground by supplying the North with better weapons. China ignored the arms embargo imposed against Hanoi and continued to supply significant amount of arms to the Northern forces. Shaplen reveals that the basic weapons for the North were Chinese-manufactured 7.62 millimeter family which were better than the traditional Vietnam guns (98).Advertising We will write a custom research paper sample on China’s Support for North Vietnam in the Vietnam War specifically for you for only $16.05 $11/page Learn More In addition to this, China stepped up its efforts to train North Vietnamese soldiers into a professional modern force that could engage in combat with western forces (Zhang). This Chinese military hardware support to Vietnam was critical to Hanoi which had suffered from international isolation in the years leading up to the war. Chinese support also included building of new infrastructure in North Vietnam to streamline the war efforts. China helped in the construction of roads in North Vietnam and an improvement of the railways. The roads serve as infiltration routes that helped to move Hanoi troops to the south in a bid to match the US escalation. The railway lines were improved so as to handle the increasing flow of Chinese supplies to North Vietnam. Also, China undertook efforts to reinforce Hanoi’s defenses. In anticipation of a US amphibious assault, China engaged in the construction of defensive works in the northeast islands and the coast between Haiphong and Hon Gai (Shang, 748). The Vietnam War was characterized by heavy bombardment of North Vietnam targets by American forces. This ever-widening pattern of bombing which aimed at weakening the North greatly damaged infrastructure and property. The North undertook projects to repair this extensive bomb damages. China assisted and as of 1965, Shaplen records that over 100,000 Chinese volunteers were involved in the repairing of bomb damages in North Vietnam (95). In late 1965, Chinese troops were engaged in repairing a 554 kilometer stretch of railroad that had been damaged by US air attacks. Zhang highlights the effectiveness of Chinese repair efforts by revealing that while the rail complex at Kep was bombed nearly 50 times and was severely damaged from each strike, it was always quickly repaired and in fact remained operational for the entire duration of the air war (755). In recognition of the aerial threat that US posed, China dispatched a fighter regiment which consisted of 36 MIGs to North Vietnam. These aircrafts were based a few miles outside the capital city of Hanoi and they were aimed at ensuring air defense in case of US invasion (Zhang 741). In addition to this, China also sent a number of air force engineers to help with the upgrading of airfields which were meant to be used by jet fighters. Vietnamese pilots were also trained to operate the war planes in to enable them to wade of US aerial attacks. Zhang notes that while the presence of these Chinese-made MIGs would not pose any threat to the superior American air power in Vietnam, the fighter planes meant that any US air raids would carry with them a real risk of retaliatory attacks from North Vietnamese a ir force (741).Advertising Looking for research paper on asian? Let's see if we can help you! Get your first paper with 15% OFF Learn More Supply routes are a critical resource in any war since they are the bloodline of the war. In the Vietnam War, the supply routes used by the Northern forces were under continued attacks from American bombardment. The Chinese troops helped to maintain the vital supply route from China to Vietnam (Gilbert 85). Before 1965, most supplies to Hanoi were by sea route. These same routes could not be used during the war since the US Navy launched a number of sea operations that effectively closed off the sea route for Chinese shipments. Zhang documents that China build a special transport line that went to South Vietnam vie Cambodia for supplies to the Northern forces that were engaged in the region (749). When this route became inadequate due to the increased number of Northern forces in the South, China assisted Hanoi to improve the Ho Chi Minh Trail which traversed eastern Laos into South Vietnam (Rosenau). The American forces made use of their air force for a number of tasks including: r econnaissance, attacks and transporting military personnel. To get to North Vietnam, US warplanes at times intruded into Chinese air space through the Hainan Island. While the Chinese initially ignored this intrusion on their air space, they changed their stance as the war intensified and their support for Hanoi soared. As of April 1965, the Chinese military had requested for permission to engage US warplanes that flew over China’s air space (Zhang 744). Once this permission was granted, Chinese units extensively engaged US warplanes that got into China’s air space en route to North Vietnam. China asserted that these attacks on US warplanes were retaliatory action against an invasion of China’s air space and hence were to be viewed as China protective herself. However, this was not entirely true since the US had in numerous occasions assured China that it had no intention of invading China. As a matter of fact, the warplanes took care not to hit any Chinese targ et and tried to steer off Chinese air space. The attacks on US warplanes were therefore action in direct support of North Vietnam which China considered to be a Comrade. As US strikes against North Vietnam intensified, North Vietnamese leaders requested Beijing for a consignment of Chinese volunteer pilots and fighters in April 1965. Vietnam’s leader Le Duan’s stated that the presence of Chinese forces would not only assist in the defense of Hanoi from US air bombardment but it would also raise the morale of the Vietnamese people and therefore increase their likelihood of pushing on with their war efforts (Zhang 747). In response to this request, China mobilized some of its troops for deployment in Hanoi. Shang states that the first Chinese deployment to Hanoi consisted of three special division sized units that were designated as â€Å"the Corps of the Chinese Rear Services† (125). Chinese fighters served as a strategic reserve that was to be used in the event of an American led invasion by the South into Hanoi. These Chinese reserve forces were placed under the command of Hanoi greatly boasting the Northern military capacity. The deployment of Chinese troops had a number of positive implications for North Vietnam. To begin with, Chinese troops mitigated the escalation of the US war in Vietnam. In addition to this, Chinese forces took up the task of defending Hanoi and as such, Vietnamese troops were freed up to go to the South and engage in offensive action. Discussion and Conclusion Without a doubt, Chinese support to the North had huge implications on the War. To begin with, China’s support was unequivocal and even General Vinh who commanded the Northern Army acknowledge that â€Å"China gives us wholehearted support† (Shaplen 98). Duiker notes that the goal of North Vietnam in the war was not to defeat its enemy but rather to prevent the US from controlling South Vietnam (30). As of the 1960s, North Vietnam was one of th e world’s poorest nations lacking a modern army and without an arms plan, both of which were vital to the war effort. It is therefore inconceivable that Hanoi would have managed to achieve its objective without outside help. It was China’s large scale infusion of aid that enabled North Vietnam to survive the war and indeed achieve its objectives. The huge support received by Vietnam from the Chinese was a direct attempt by China to stop the perceived spread of American imperialism and challenge the Soviet’s leadership of the International Communism movement. In addition to this, China was committed to the success of the war of national liberation that it encouraged Hanoi to engage in. This paper set out to highlight how China supported North Vietnam in the Vietnam War. To this end, this paper has discussed the specific means through which China demonstrated its support for North Vietnam. China made a promise that she would regard Vietnam’s problems as her own and was throughout the war the major ally for Hanoi. From the arguments presented in this paper, it is clear that Chinese assistance was crucial to the success of North Vietnam in the war and it is inconceivable that Hanoi would have faired as well as it did without Chinese support.

Andregernic blocking drugs Essay

Andregernic blocking drugs Essay Andregernic blocking drugs Essay Adrenergic blocking drugs General Principals (Class) Beta adrenergic blocking agents prevent stimulation of the beta adrenergic receptors at the nerve endings of the sympathetic nervous system and therefore decrease the activity of the heart. They block sympathetic stimulation of the heart and reduce systolic pressure, heart rate, cardiac contractility and output, so decrease myocardial oxygen demand and increase exercise tolerance (agents, 2013) Indications Adrenergic blocking agents are used to treat angina, control abnormal heart rhythms and to reduce high blood pressure (agents, 2013). They are also used to treat a variety of other conditions including benign prostatic hyperplasia and Reynaud’s disease (Blockers, 2013). Cautions Adrenergic blocking drugs are typically not used on people with asthma because they may trigger severe asthma attacks. Also with people who have diabetes, adrenergic blocking drugs may block signs of low blood sugar, such as rapid heartbeat (Blockers, 2013). Mechanism of Action To interrupt the stimulation of the SNS at the alpha 1- adrenergic receptors. Alpha blockers work to bind and antagonize receptors by blocking norepinephrine making it non responsive called a competitive blockade. A covalent bond makes receptors less responsive but responsive in a small amount to norepinephrine called a noncompetitive blockade. Adverse Effects Sudden drop in blood pressure after the first dose called the first-dose phenomenon, causing the patient to pass out. Cardiovascular palpitations, tachycardia, edema and angina. Nausea and vomiting, diarrhea, constipation, dry mouth and abdominal Toxic Effects In the case of an overdose, activated charcoal is the standard choice of med because after administered it binds to the drug and is removes it from the stomach and the circulation. Supportive measures include vitals, fluids, and anticonvulsants such as diazepam for the control of seizures. Route of Administration Alpha1 Blockers Mostly administered orally(PO) Except for phentolamine, administration routes are intravenous(IV), intramuscular(IM), and subcutaneously(subcut) Phentolamine can be used for extravasation of vasoconstricting drugs(e.g., norepinephrine, epinephrine, and dopamine) subcutaneously(subcut) in a circular fashion around the extravasation site to increase blood flow to the ischemic tissue and thus prevent permanent damage. Beta Blockers Nonselective Mostly administered PO Labetalol(Normodyne, Trandate) and propranolol(Inderal) are administered PO and IV Timolol PO, IV, and ophthalmic for glaucoma (Skidmore-Roth, 2013) Cardioselective Mostly administered PO Metoprolol (Lopressor, Toprol-XL), PO and IV Esmolol (Brevbloc) IV only (Lilly Lane, Rainforth Collins, & Snyder, 2014) Common Drug Interactions Antacids (aluminum hydroxide type) Decrease absorption resulting in decreased beta blocker activity Antimuscarinics and Anticholinergics Antagonism resulting in reduction of beta blocker effects Digoxin Additive effect, enhancing bradycardic effects of digoxin Diuretics, cardiovascular drugs, alcohol Additive effect resulting with additive hypotensive effects Neuromuscular blocking drugs Additive effect by prolonging neuromuscular blockade Oral hypoglycemic drugs and Insulin Mask signs of hypoglycemia and delay recovery from hypoglycemia (Lilly Lane, Rainforth Collins, & Snyder, 2014) Nursing implications for patients taking Adrenergic Blocking Drugs include: Patient teaching (Lilly, Collins, Synder, 2014, Pg 319-322) Wear a medical alert bracelet or necklace Carrying around a list of medications and specific diagnosis around with them at all times Take medication exactly as prescribed and never to stop the medication abruptly Avoid caffeine and other CNS stimulants Avoid consuming any alcohol Contact your doctor immediately if and when you experience any of the following: Palpitations, chest pain, confusion, weight gain of 2

Week 4 reflection paper ZHA Assignment Example | Topics and Well Written Essays - 250 words

Week 4 reflection paper ZHA - Assignment Example Thomas observes that diseases do not develop as a consequence of carelessness in the prevention of health, rather diseases are a result of blind accidents which we do not have control over most of the times(41). Additionally, he observes that germs are everywhere; therefore, we employ all manner of chemical prevention methods such as disinfectants. However, he poses that it is our body‘s reaction that is a threat to our lives, not the bacterial invasion (Thomas). I find this an interesting perception. It is relatively true because extreme body reactions to foreign bodies such as in the case of hypersensitivity reactions in Steven Johnson’s syndrome result in extensive burn-like lesions. Philmus and Hughes opine that a living thing is a complete realization of birth possibilities, and it is sometimes confused with theological predestination (2). They note that although we may modify and recast the human body, the changes would in no way change the offspring (Philmus and H ughes). Mistelli posits that the arrangement of genes and their movement profoundly influence the body functioning in health and disease (68). In a video exposition, medical illustrator David Bolinsky explains that the body is in constant functioning at the cellular level (Bolinsky). Indeed, the body and its interaction with disease-causing agents is a fascinating discovery. Though we may not know even a percent of it, once we figure it out we would have more control of our

Please agree with him Mr. J. and write 3 pages cite sources. Cite sources.(Dhibba Shan) - Article Example Borrowed nursing theory is a theory which was originally designed to suite in another discipline, but later adapted also to fit in the nursing profession. However, it is worth understanding that the nursing perspective guides the reconceptualization of existing theories. Synthesis of the borrowed theory with the nursing perspective is essential; otherwise the focus of nursing will continue to remain within other disciplines. Consequently, nursing problems will either not be addressed at all or addressed haphazardly. Therefore, theories from other disciplines must be incorporated into both the nursing milieu and to the nursing image of a human being to be meaningful to nursing (McEwen and Evelyn, 2007). Nurses heavily borrow theories from physical, biological and behavioral science disciplines and adapt them to nursing situations. As a result, a nursing theory emerges though tracing its origin on the original discipline. A theory that is applicable in two or more different disciplines is referred to as shared theory. Examples of borrowed theories include the Von Bartlaffny’s general systems theory and Maslow’s Hierarchy of Human Needs. In a case scenario, nurses can apply the Maslow’s theory to predict the needs that patients have not expressed clearly so that appropriate actions can be undertaken (Fawcett, 2005). For example, when a patient is admitted in the hospital, it is the duty of the nurses to organize a familiarization program for the patient, which helps them relieve anxiety and feel comfortable in the hospital environment. Existence of borrowed theories certainly implies that unique theories also exist. These are theories which were specifically designed to guide nurses’ decisions, goals and actions that relate to their profession. While formulating these theories, the theorists base their opinions and assertions on experiences and researches that directly relate to

How Nafta has been framed since inception Research Paper

How Nafta has been framed since inception - Research Paper Example While discussing treaties and agreements, it is essential not to leave out the diverse types of agreements which are considered the most important and imperative. Some of these essential conformities include International Investment Agreement, International Taxation Agreements and most importantly Trade and Commerce Agreements. The most widespread term that we see when trade agreements are discussed, is â€Å"NAFTA†. The North American Free Trade Agreement (NAFTA) is one of the most important accords signed by the American government. This agreement has been shared with the governments of two most central bordering areas of the United States i.e. Mexico and Canada. This agreement came into power on January, 1994. The administrative centers of this agreement are in Mexico City, Ottawa, and Washington, D.C. NAFTA was signed between President George H. W. Bush of US, Prime Minister Brian Mulroney of Canada and Mexican President Carlos Salinas. Following were the advantages and motivations of the generation of this agreement: NAFTA was signed by the three countries to amplify the trade the trade process so that more and more items could be imported and exported to and from these countries. It was about time that the trio apprehend and grasped the magnitude of trade for their realms. As Tamarkin and Bayer have clarified that â€Å"The lifeblood of global connections is world trade. There is evidence of human trading from prehistoric times.† (288) and this specifies the importance of trade and dealing for countries. As far as the area of benefit is concerned when it comes to the state of Mexico, signing this agreement was important because the NAFTA agreement ostensibly eggs on superior colonization among the trio. The increased immigration from Mexico to the US has become even more of a flashpoint. Although this is not the case when it comes to the relationship between Canada

Carrying out an open-loop step response on the process trainer pt326

Carrying out an open-loop step response on the process trainer pt326 INTRODUCTION: The control systems are based up on the behaviour of the dynamics systems and it is also a branch of the engineering and mathematical model of the process. The desired output of the system is called as reference. A controller is device which observes and outcome the changes in the output that are affected by the input variables. And it is also used to operate the input variables to a system to achieve the desired result on the output of the system. It is very simple and flexible to solve using the mathematical model. In control system design, we have a concept of feedback control system. The main concept of this feedback loop is to control the system performance and it is a negative feedback because the sensed value is subtracted from the desired value to produce the error signal which is amplified by the controller. To avoid the problem of the open-loop control system, the control system initiated the feedback loop. Where as in closed loop system, the control system uses the feedba ck to control the output of the process. One of the most widely used controllers in the design of continuous data control system is the PID controller, where PID stands for the proportional plus integral and derivative control. The PID controller is mostly used in the feedback control design. The controller is used for the operation of the error signal to produce the control signal. Proportional (P) control: This is the one type of action performed and used in the PID controllers is the proportional control. It is the simplest form of continuous control system that can be used in the closed loop system. Proportional control is used to minimize the fluctuation in the process, but it does not allow to bring back to the required set point. P-only controller provides the faster response than other controllers. The system first allows the P-only controller in order to get the system a few seconds/minutes faster. The main advantage of the P-only controller is the faster response time, it produces the deviation from the set point and this deviation is called offset. Mathematical Equations: P-only controller linearly correlates the controller output (actuating signal) to the error (difference between measured signal and set point). In the mathematical form, the p-controller is given below Y(t) = Kc e(t) + b Where Y(t)= controller output Kc = controller gain e(t)= error b= bias In the above equation the controller gain and bias are constant to each controller. The controller gain is the change in the controller output per change in the controller input. Bias is simply a controller output, when the error is zero. In the PID controller, when the signals are transmitted then the controller gain relates the changes in the output voltage to the changes in the input voltage. Thus, the gain ultimately changes in the input and output properties. If the controller output changes more than the input, Kc is greater than one. If the change in the input is greater the controller output, Kc is less than one. Ideally, Kc is equal to infinity then the error will be reduced to zero. Exact equalities cannot be achieved in the control logic. In this, the error will be allowed up to certain range of the system. Integral (I) Control: This is another type of action performed in the PID controllers is the integral control. Integral control is the second form of feedback control system. It is obtained used to remove the deviations that may exit. Thus the system moves to the steady state and original settings. A positive error will cause the signal to be increase and whereas a negative error will cause the signal to be decrease the system. However, I-only controller is much slower in response time than the P-controller. Thus, the slower response time will be reduced by combining with another form such as P or PD controller. It is often used to measure the required variables to remain within a narrow range and also require a fine tuning control. Mathematical Equations I-controller correlates the controller output to the integral of error. The integral of error is taken with respect to time within a specified interval. In the mathematical form, the I-controller equation can be represented as Where C(t)= controller output Ti = integral time e(t)= error c(t0)= controller output before integration. Derivative (D) Control: This is another type of action performed in the PID controllers is the derivative control. I-control and D-control are a form of a feed forward control. D-control anticipates the process conditions by analyzing the change in error. It main function is to minimize the change in error, thus keeping the system in a consistent setting. The main benefits of the D-controller is to resist change in system, the most important of these being is oscillations. PI-controllers: PI-controller is a combination of both proportional plus integral controller. This is the feedback controller which drives the process/plant to be controlled with sum of error and also the integral of that value. In PID controllers, we have not yet used the D-controller (D=kd=0). The basic block diagram of the PI controller is shown below, The controller output for the above closed loop system is Where ÃŽ is the error of actual measured value from the desired set point. ÃŽ = SP PV. The main advantage of the PI controller; the integral terms in the PI controller causes the steady state error to be zero for a ramp input. The main disadvantes of using with the PI controller is the phase lag. This means that the phase margin decreases. Required Apparatus: The report of this experiment is carried out on the Feedback Process Trainer, PT326. The design of the control system consist of a computer ,A/D and D/A converters, and a printer used to provide the copies of the response system. The networked PCs used to obtain the system design using the nyquist simulation method employing the design and simulation program CODAS. Explanation of PT326: According to the industrial situation, the PT326 process trainer model is commonly used. This situation appears when the temperature control is required in the presence of transport delay and transfer lags. In this PT 326 process trainer, the trainer involves air that is strained from the atmosphere through a centrifugal blower and it is heated and passed over the heater through duct before it is being heated. The objective of the control is to sustain the temperature of the air at the required level. The temperature control can be achieved by varying the electrical power supplied to the heater grid. By using the bead thermistor which is placed in the flow at any three position along the duct, the air temperature may be sensed. The process trainer introduces the transport delay in the system which is located between the thermistor and heat coil. By setting the opening of the throttle, the mass flow of the air can be adjusted through the duct. The temperature sensors can be placed at any three of the position in the duct, so that these sensors can acts as a detector. The variation in the resistance of the temperature sensor is converted to the voltage variation through the bridge circui t and is available at terminal Y. The output of the temperature sensor can be used as feedback for connecting the terminal X and Y. The required temperature can be indicated by adjusting the knob label set value. In additionally, the set value can change the step by using the command throwing the switch as internal. An external referrence input can also be provided using the label as external. The difference between referrence input set value and feedback signal is availabel at terminal B and can be supplied to the heater power supply so that the gain can be adjusted by using the prportional band. To select a continuous control, the signal at A can be send directly to the heater power supply by using the switch s. The switch s can be alternatively used as on-off controller as well as it is used to select the two step control. This on-off control command reponds to the maximum heater power when on and for the zero heater power it is off. The hysterisis is an on-off controller which can be adjusted by the knob label as overlap. The maximum heater supply can be adjusted using the knob label as max heater power. The process may be seen to comprise a simple blower in which air is drawn from the atmosphere, blown past a heater grid and along a tube having a provision for several temperature to pick up. The purpose of the control system is to maintain the temperature of the air flowing in the tubeat some required set point. The output of the process is a temperature which is measured by the use f the thermistor bead transducer and bridge circuit. Procedure: In the set of experiments of the PT326 process trainer, a personal computer acts as a contoller. Three controller are going to be investigated, a) Proportional control b) Integral control c) Proportional plus integral control. The final experiment make use of the analytical control system to show how the control theory can be used to calculate the behaviour of the control system. a) Proportional control: Using the computer program go into the controller setting menu. Set the controller to be a proportional only type i.e set the kp= 0.1, ki= 0, kd= 0. On the process trainer, adjust the throttle to 25o and place the sensor in the position away from the heater. Vary the proportional gain and plot the graph of the steady state error against the proportional gain. Choose the value of gain we think for the best response and obtain the screen dump to get a copy from the printer. Finally, indicate on graph the onset of instability. b) Integral control: Using the computer program go into the controller setting menu. Set the controller to be a integral only i.e set the kp= 0, ki=0.1, kd=0. On the process trainer leave the throttle at 25o and kep the sensor in the position away from the heater. Vary the integral gain and plot a graph of steady state error against the integral gain. Choose a value of gain that gives the best response of the system and obtain the screen dump. Finally, indicate on the graph the onset of instability. c) Proportional-plus-Integral control: Using the computer program go into the controller setting menu. Set the controller to be proportional-plus-integral type i.e set the kp=0.1, ki=0.1, kd=0. On the process trainer leave the throttle at 25o, and keep the sensor in the position away from the heater. Vary the proportional and integral gains until we get the best response from the system and obtain the screen dump. d) Open-loop step response: Using the computer program PRESS o this will put the system under the open loop control. The programme will then automatically carry out an open loop step response. Obtain a screen dump for the open loop step response. From the loop step response it is possible to calculate the transfer function of the process trainer. The tranfer function has the form: Where K is the open loop D.C gain of the system and Td is the pure time delay present in the system and Tp is the time constsnt for the system. It is possible to measure these values directly from the open loop step response. The steady state error for the control system can be derived as : Steady state error = V/(1+kp k) e) After obtaining the open loop step response values like K, Tp, Td, e and R from the graph. Place the values of K,Tp and Td in MATLAB simulink. To simulate the plant only in open loop in CODAS. Compare the time response with the actual plant open-loop response. f) Introduce the controller into the simulation and in frequency domain, adjust proportional gain to give the gain margin of 2 i.e., Nyquist plot (controller plus plant, open-loop) cuts the real axis at -0.5. observe the corresponding time response(controller plus plant, closed loop in time domain). g) Following the Nyquist method (f), introduce an integral control term and observe the time response. h) Keeping the proportional plus integral control established in (g), adjust the overall gain(k) to give gain margin of 4,2,1.333,1 and 0.8 (corrresponding to the Nyquist plot cutting the real axis at -0.25, -0.5, -0.75, -1.0 and -1.25 respectively). Comparing the corresponding time responses on the same graph. i) Now,changing the overall gain back to 1 and substituting the proportional and integral gains as calculated using the (i) ziegler-Nichols and (ii) cohen and coon formulas.

The Extraordinary Family in Judith Guests novel, Ordinary People :: Judith Guest Ordinary People Essays

The Extraordinary Family in Judith Guest's novel, Ordinary People    Judith Guest's novel Ordinary People evinces some main principles of the modernist literary movement, such as the philosophy that modern man is beset by existential angst and alienation. According to Carl Marx, a renowned existentialist, alienation, as a result of the industrial revolution, has made modern man alienated from the product of his own labor, and has made him into a mechanical component in the system. Being a "cog in the wheel" prevents modern man from gaining a sense of internal satisfaction of intellectual and emotional pleasure. Further more, according to Sigmund Freud, there are two pleasures, work and love. Consequently, Freud would say that being disconnected from pleasure from work, half of the potential for psychological fulfillment would be lost. Modern man is suffering from alienation as a result of large institutions, and as individuals, modern man neither feels that they are part of them nor can understand them. Additionally, the existentialists say , man is shut out of history. Modern man no longer has a sense of having roots in a meaningful past nor sees himself as moving toward a meaningful future. The modern man also suffers from alienation in his relationships with other people. Since he lives life not authentically and not knowing who he is, he cannot relate to others authentically. Hence, there are no real relationships at work and there are no real relationships of love. Also, according to Sartre, modern man is absolutely not a victim of his environments, of his childhood, and the circumstances in his life. The events in life are only neutral and since modern man is free, he chooses the meanings of the facts of his life. Modern man lives in a constant state of existential angst, which is dread of the nothingness of human existence and the fact there is no underlying purpose to human existence or set of objective truths or morals by which to navigate life. According to Martin Heideggar, German existentialist philosopher, the unaware person tries to escape the reality of death by not living life to the fullest. However, death can be the most significant moment for the individual, his defining moment of personal potential, if accepted and confronted squarely will free the individual from anxiety of death.
