Kate in all my sons free essay sample

?How does Miller use representations of speech and other dramatic techniques to present the character of Kate in this extract and in one other extract in the play? Section from the start of act 3 to the stage direction – â€Å"Jim exits to driveway† To beginact 3, Arthur Miller uses dramatic stage directions to set the scene. These stage directions present the character of Kate in a deranged way. It says that she is rocking â€Å"ceaselessly† in a chair. The use of the adverb â€Å"ceaselessly† suggests that her temperament is somewhat unstable. Following these stage directions, Miller begins the dialogue of the extract with an interrogative utterance from Jim – â€Å"any news? †, it is interesting that Jim comes straight in with a question and doesn’t form a phatic utterance to begin conversation with Kate. It makes the atmosphere feel more formal and dull. Kate’s response is extremely short which means she isn’t open to any other sort of conversation with Jim â€Å"no news†. We will write a custom essay sample on Kate in all my sons or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page This adjacency pair makes it clear that kate is not one for phatic conversation, this is known by Jim who doesn’t attempt any ‘chit chat’ with her. when Jim says –â€Å" you cant sit up all night, dear, why don’t you go back to bed? †, in brackets, it says that he speaks gently. This has the connotation that Kate is fragile and requires to be spoken to in a gentler manner. The character of Kate is displayed at depressed. Miller does this by the short and limited replies she gives Jim. An example to show this is when Jim says – â€Å"don’t be afraid, Kate, I know, I’ve always known† and all she says back is â€Å"how? †. This one – worded interrogative utterance tells us that she is disinterested in what Jim has to say and also that she has other burning issues on her mind. Also when Jim explains and describes to Kate in detail how chris is going to come back and he makes an effort to convince her and put her mind at ease. Regardless of his effort, kate still replies coldly with a short â€Å"just as long as he comes back†. It is almost as if she doesn’t recognise that Chris is trying to be kind to her. this shows the character of kate in a unfriendly light. the second extract is in act one when kate gives a speech which explains the dream she had about Larry.

Dr. Martin Luther King Jr. essays

Dr. Martin Luther King Jr. essays Martin Luther King Jr. was born in Atlanta, Georgia on January 15, 1929. He was the oldest son of the Rev. and Mrs. Martin Luther King. He was named Michael Luther after his father but he later change it to Martin Luther after the great church leader. Bad racial experiences made a long lasting impression on Martin. One day the parents of the boys Martin played with told him they could not play with him anymore because he was black and they were white. That broke his heart and he ran home and told his mother. His mother tried to explain to him why it happen,so she talk to him about racism and prejudice people. She told him that although blacks were no longer slaves, they were not really free. Martin grew up doing and liking what other kids like baseball, basketball and wrestling, but he liked reading most of all. He liked reading mostly about famous people in black historyand he liked to learn new words and use them. He also liked listing to his father and the other ministers use strong words when they preached. He wanted to follow in their footsteps. He made words his weapon for defense and offense. Martin once told his mother Im going to get me some big and strong words like the other preachers. When he was in high school, his skills to use words got him to win an oratorical contest. In September 1944, when he was only 15 years old, Martin entered Morehouse College in Atlanta, Georgia. It was an all black school, and his father and grandfather went there. He knew his father wanted him to become a minister, but Martin was not sure that that was what he wanted to do. At first, he was not sure what his course of study he was going to do, but his experiences at Morehouse shaped his direction for life. It was not until after the meeting with Dr. Benjamin E. Mays, the college president; and Professor George Kelsey, head of the religion department; that he made up his mind. Marti ...

South African Economy Essay Example | Topics and Well Written Essays - 1500 words

South African Economy - Essay Example 4Governor Tito Mboweni signaled repeatedly in the past month that lending rates were set to rise again as underlying inflation become "more generalized", while stricter lending rules had so far failed to dent robust consumer spending and credit demand. 5 For the current business cycle, however, the hikes that were made to the country's interest rates recently are generally being considered to be the last. The causes of high inflation in South Africa primarily are two external causes; "The current price drivers are rising oil and international food prices, simply because demand outstrips supply in the international market for these products. The two are linked because the immediate effect of increased fuel prices is that it becomes more expensive to produce food, but this on its own does not necessarily lead to a general price rise." 6 Besides the policies of the South African government are not above contempt, and in fact these populist policies to appease some sections of the countrymen without concern or acknowledging the external causes in plunging the economy into despair. "Increased interest rates will have a direct effect on tax collections and therefore a direct effect on subsidizing the poor. This will lead to a rapid depletion of budget surplus, and to fill this gap the government has no option but to print money to fill in the gap." 7 This is leading South Africa towards hy perinflation. Impact of high oil prices on South African economy The high oil prices have severely affected oil importing countries like South Africa, whose capacity to generate electricity has been affected and which has "forced them to ration electricity". 8 Adding further, "The high price of oil impacts directly on firms, consumers and the government. First, it increases the domestic price of petroleum products, raises the cost of many immediate inputs, and as a result leads to higher production costs. Consequently firms may reduce their labor demand, investment and output. Second, as the short-run demand for oil is highly inelastic, consumers are forced to reduce their consumption of other goods and services to pay for higher energy bills." 9 Moreover, the rising oil prices will also affect South Africa's balance of payments, as exchange rates will work against them in international trade, this will reduce their level of economic activity since the amount of affordable oil that South Africa will be able to purchase shall be dramatically reduced under present conditions. "Consumers and firms could decide to reduce their oil consumption but since the demand for oil is highly inelastic in the short-term, they may be compelled to reduce their consumption of other imported goods. Doing so could undermine economic growth especially if capital goods imports are affected." 10. Poverty is another issue facing the South African economy, since the current policy will lead to more widespread poverty as lack of adequate fuel will drive up the cost, with the cost of transportation of goods and

How We Live and Die Assignment Example | Topics and Well Written Essays - 500 words

How We Live and Die - Assignment Example 1. Artificial haemoglobin is a critical innovation, because it will solve blood supply problems and help save lives in the future. Its production, however, remains on the works, which means that in the meantime, we have to still rely on blood donations as one of the ways of giving and receiving blood. 2. Knowledge of the role of the circulatory system is crucial in understanding exhalation, because it affects the human heart rate. A good heart can exhale the bad air out and exhaling properly should also be emphasises in breathing exercises. 3. The formula for blood pressure will be important in understanding how to have a healthy heart, because it defines the factors that affect it. Knowing these factors for each person will help them understand possible underlying circulatory problems. 1. I changed my mind that breathing is a simple matter, because it involves interdependent relationships among the respiratory, circulatory and nervous systems. If the brain is not working, the heart and lungs will not work properly too. At the same time, people with circulatory and respiratory problems can also affect how their brain works, especially when the brain needs 20% of total body oxygen consumption. 3. I now believe that second-hand smoke truly kills, since breathing involves numerous bodily systems, so if we breathe smoky air from others, this poisonous air pollutes too many important body organs and tissues. 2. I want to read on devices that can help people breathe better, when they have lung, brain, or circulatory issues, because I want to know how far technology has come to replicate or support human

Nonlinear Generalized Companding Transform

Nonlinear Generalized Companding Transform Nonlinear Generalized Companding Transform for  Peak-to-Average Power Ratio Reduction in OFDM Eashendra Singh Abstract  Ã¢â‚¬â€ One of the main drawback of Orthogonal Frequency Division Multiplexing (OFDM) system is its high Peak-to-Average Power Ratio (PAPR) of the OFDM signal. In this paper a novel non-linear generalized companding scheme called â€Å"Quadrilateral Companding Transform (QCT)† has been proposed to reduce the PAPR of OFDM signal. The proposed method provides additional degrees of freedom in comparison to existing trapezoidal companding, exponential companding and trapezium distribution based companding schemes. This allows more flexibility in designing the companding function, which is useful for the overall OFDM system to achieve low BER with good PAPR reduction capability. Keywords   Complementary cumulative distribution function  (CCDF), peak-to-average power ratio (PAPR), orthogonal frequency division multiplexing (OFDM), bit error rate (BER). INTRODUCTION The modern day phenomenon of increased thirst for more information and the explosive growth of new multimedia wireless applications have resulted in an increased demand for technologies that support very high speed transmission rates, mobility and efficiently utilize the available spectrum and network resources. OFDM is one of the best solutions to achieve this goal and it offers a promising choice for future high speed data rate systems [1], [2]. OFDM has been standardized as part of the IEEE 802.11a and IEEE 802.11g for high bit rate data transmission over wireless LANs [3]. It is incorporated in other applications and standards such as digital audio broadcasting (DAB), digital video broadcasting (DVB), the European HIPERLAN/2 and the Japanese multimedia mobile access communications (MMAC) [4], [5]. However, a major drawback of FDM systems is the high peak-to-average power ratio (PAPR) of the transmitted signals, resulting in the lower power efficiency, serious signal distortion an d out-of-band radiation when the high power amplifier (HPA) is utilized. Many companding schemes [17]-[23] have been proposed in the literature to reduce the PAPR of OFDM signal. The conventional ÃŽ ¼ law and A-law companding schemes can be used for PAPR reduction, by choosing the suitable value of the parameters ÃŽ ¼ or A, controlling the nonlinearity of the ÃŽ ¼ -law [17] or A -law companding function respectively. But the error performance of both the schemes degrades as both of them introduce high companding distortion in OFDM signal at higher values of ÃŽ ¼ or A. A nonlinear companding transform [18] has been proposed by Jiang et al. to effectively reduce the PAPR of the OFDM signal. In this scheme [18], the Gaussian distributed in-phase (I) and quadrature-phase (Q) components of discrete time complex OFDM signal are transformed into a quasi-uniform distribution. In this scheme, the companding function is separately applied to I and Q components of the OFDM signal. The large values of I or Q components of the OFDM signal are compressed, whereas thos e with small I and Q components are enlarged. The PAPR reduction capability and BER performance of this scheme [18], can be optimized by properly choosing the parameters of the companding function. Jiang et al. proposed â€Å"Exponential Companding (EC)† scheme [19] to transform Rayleigh distributed OFDM signal magnitude into uniform distribution. Exponential companding has the advantage of maintaining the constant average power level in the nonlinear companding operation. However, the distribution of large signals is increased by the uniform companding, which makes the PAPR reduction was very limited under the bit error rate (BER) performance degradation. In this paper proposed technique transform the Rayleigh distributed OFDM signal magnitude into Quadrilateral distribution function as shown in figure 2 to achieve an additional degree of freedom over TC [22]. The parameters of quadrilateral distribution are chosen in such a way that it produces least possible companding dis tortion to achieve low BER for a given PAPR. The remainder of this paper is organized as follows: In section II, the OFDM system model with quadrilateral companding. The proposed quadrilateral companding and decompanding functions are derived in section III. Mathematical analysis of the PAPR performance of proposed scheme is presented in section IV, simulation results for PAPR performances of the proposed scheme are presented and discussed in the same section and conclusion is summarized in section V. SYSTEM MODEL The block diagram of an OFDM system using companding scheme for PAPR reduction is shown in Fig. 1. Here, I have considered an OFDM system with N subcarriers, in which each of the subcarrier is each of the subcarrier is modulated by M-PSK or M-QAM. As shown in Figure 1.The input binary data sequence is first converted into N parallel data substreams and then these are mapped to the constellation points of M- PSK or M-QAM to achieve desired modulation on each of the subcarriers. After this, subcarrier modulation is performed using IFFT block to obtain the discrete time domain OFDM signal. Let be the N complex modulated data symbols to be transmitted over N subcarriers. The discrete time domain OFDM signal generated after taking IFFT of a block of N modulated data symbols. Discrete time domain OFDM signal is passed through the parallel to serial (S/P) converter and then applied to the compander for reducing the dynamic range or PAPR of the OFDM signal. The companded OFDM signal is appl ied to digital to analog (D/A) converter to get analog signal and then finally amplified using HPA. At the receiver, the received signal is first converted into digital signal using A/D converter. Data in Data out Figure 1. Block diagram of OFDM with companding The digital signal is then expanded by inverse companding function known as decomapnding function. After that subcarrier demodulation is performed by taking the FFT of OFDM signal obtained from expander. Finally, M-PSK or M-QAM decoder is used to decode the received data signal.      PROPOSED COMPANDING TECHNIQUE The quadrilateral companding function h(x) is a nonlinear companding function. It transforms the original probability distribution function of OFDM signal magnitude into a quadrilateral distribution as shown in Figure 2, and hence the name â€Å"Quadrilateral Companding Transform†.This may also be called nonlinear generalized companding transform. Figure 2. Quadrilateral distribution for proposed QCT The symbols notation used throughout this paper are listed in Table 1 for convenience. Table 1: List of symbols used in QCT kth modulated data symbol nth sample of discrete time domain OFDM Signal PDF of original OFDM signal (without companding) CDF of original OFDM signal (without companding) PDF of OFDM signal after companding CDF of OFDM signal after companding Upper-bound of the peak value of OFDM signal Quadrilateral Companding function Quadrilateral Decompanding function The pdf of quadrilateral trapezium distribution can be read from Figure 2 as where h1 , h2, l, a and b are the parameters of quadrilateral distribution as shown in the Figure 2.These parameters (h1 , h2, l, a and b) control the nonlinearity of the companding functions. The cumulative distribution function (CDF) of quadrilateral distribution function can be calculated using the following relationship (2) Using (1) and (2) we have Quadrilateral distribution function is bounded in the interval [0,l]. Like EC, TC and TDBC, in this scheme also average power of the OFDM signal before and after companding is kept same, therefore we have (3) As shown in Figure 2, the PDF of quadrilateral trapezium companded OFDM signal lies in the interval [0,l] , therefore, we have, (4) For given values of l, a and b, the parameters ( h1 , h2 ) of the companding function h(x) can be easily calculated using (3) and (4). Therefore, three parameters (l, a and b ) can be chosen independently to control the nonlinearity of companding function h(x) . Hence the proposed QCT has three degree of freedoms. The values of l, a and b should be chosen independently to provide low PAPR and BER. The expression of QCT function h(x) can be derived after equating the CDF of original and companded OFDM signal. Therefore, we have Where is the CDF of original OFDM signal given by following: (5) Therefore we have The output of the N-point Inverse Fast Fourier Transform (IFFT) of are the OFDM signal sample over one symbol interval, or mathematically, Where E [.] denotes the expectation operator. PERFORMANCE ANALYSIS In [22], the PAPR and BER performance of TC has been evaluated for (a = 0.4,b = 0.1 and l = 1.633) , (a = 0.2,b = 0.7 and l = 2.164) , (a = 0,b = 0 and l = 1.732) , (a = 0.9, b = 0.1 and l = 1.488) and (a = 0,b = 1 and l = 2.449) , here we refer to them as ‘TC-1’, ‘TC-2’, ‘EC’, ‘TC-3’ and ‘TC-4’ respectively. In [22], it has been shown that TC-3 provides the best PAPR reduction capability among all the cases under consideration, but its BER performance is very poor, on the other extreme TC-4 provides very less PAPR reduction. Therefore, we ignore these two cases (TC-3 and TC-4) and the remaining three cases i.e. (TC-1, TC-2 and EC), which offer reasonable PAPR are considered in my simulations for comparison with the proposed scheme. To show the outperformance of the proposed scheme (QCT), the PAPR and BER performances are evaluated for two sets of companding function parameters i.e. (a = 0.2,b = 0.7,l = 2.174, h1 = 0.8596 and h2 = 0.8275) and (a = 0.4,b = 0.1,l = 1.643, h1 = 0.8276 and h2 = 0.7874) . Here, we call them as ‘QCT-1’ and ‘QCT-2’. Figure 3. PAPR performance comparision of original and companded signal Figure 4. BER performance comparison of various  companding schemes CONCLUSION The QCT provides extra degrees of freedom to design the companding function and hence by choosing the suitable values of design parameters of the proposed companding function, a good trade-off between the PAPR reduction and the BER can be achieved. The proposed QCT provides better PAPR reduction and BER performance in comparison to TC, EC and TDBC. QCT can achieve a minimum PAPR of 0dB, whereas TC and EC can achieve a minimum PAPR of 3dB and 4.771dB respectively. QCT-2 has superior PAPR performance in comparison to QCT-1 but its BER performance is inferior in comparison to QCT-1. References L. J.
