...Metamorphoses in Dune Alexandru Maniu In Dune, people can be both men and animals. For purely artistic reasons, the coexistence of different life forms under the same mask is a constant in Ovid’s Metamorphoses. In Orphism, nothing is immutable and everything is subject to change. For Ovid, this postulate must have had some limits generated by the artistic process: “nor can the arts that cure others cure their lord”. Transformed characters – so punished for ill behavior or challenging the gods – eventually acquire immortality, just like the poet himself. Deities can be either anthropomorphic or theriomorphic, yet they can change according to their own will and they don’t lose their divinity in the process. Ovid’s metamorphoses are usually final and the poor misfortunate loses some of his humanity forever. By far the cruelest fate is for one to lose his power of speech or his free-speech, as in the case of Acteon, changed into a stag, Callisto, changed into a bear or Lycon, who becomes a wolf. On a more subtle level, the nymph Echo is left only with the power of speech, but her words are not her own, as she is forced to repeat whatever she hears. All these stories cover a more complex level of understanding that deals with religion and ritual, and should not be taken as mere parables of morality. The myth of Artemis and Acteon encapsulates the confrontation between crude human conscience and the mystery of life, epitomized by the maternal deity (Isis, Artemis, Diana), with...

...Relationships in Alias Grace The truth may not always be as black and white as it seems. In Margaret Atwood’s Alias Grace, the main character is immediately judged and harboured as a criminal. The book is about a woman, who, at the age of sixteen is tried in the court as an accomplice to a double murder. It is a true story that happened in Canada in the 1850`s. A lot of mystery surrounds the role she actually played in the murders because some of the facts do not add up. There are competing versions of the story, and Grace herself has no memory of the event. She confesses, but the story quickly reveals that her lawyer coerced her into giving the version of the story that he liked best. Meanwhile, Grace is prone to mental fits that no one understands, so countless doctors and clergymen examine her and come to differing conclusions; some are convinced that she is guilty, and others are convinced that she is innocent. One of the only things keeping Grace strong is her ability to connect with certain characters that are introduced into her life. The use of her qualities and strengths as a woman allows Grace the ability to hold onto certain relationships longer than others. Grace not only has the ability to draw people into her life, like Doctor Simon Jordan and Mary Whitney, but she is able to entice the reader in ways that others cannot and bring them in as her fascinated audience. To begin with, one of the main characters in Atwood’s novel, Alias Grace, is Doctor Simon...

...Arithmetic and geometric progressions mcTY-apgp-2009-1 This unit introduces sequences and series, and gives some simple examples of each. It also explores particular types of sequence known as arithmetic progressions (APs) and geometric progressions (GPs), and the corresponding series. In order to master the techniques explained here it is vital that you undertake plenty of practice exercises so that they become second nature. After reading this text, and/or viewing the video tutorial on this topic, you should be able to: • recognise the difference between a sequence and a series; • recognise an arithmetic progression; • find the n-th term of an arithmetic progression; • find the sum of an arithmetic series; • recognise a geometric progression; • find the n-th term of a geometric progression; • find the sum of a geometric series; • find the sum to infinity of a geometric series with common ratio |r| < 1.

...A Taylor series for the function arctan The integral If we invert y = arctan(x) to obtain x = tan y, then, by differentiating with respect to y, we find dx/dy = sec2 y = 1 + tan2 y = 1 + x2 . Thus we have (ignoring the constant of integration) y = arctan(x) = dx . 1 + x2 (1) If we now differentiate y = arctan(x/a) with respect to x, where a is a constant, we have, by the chain rule, y = 1 a 1 a = 2 . 1 + (x/a)2 x + a2 (2) Thus we obtain the indefinite integral 1 dx = arctan(x/a). x 2 + a2 a (3) The Taylor Series By expanding the integrand in (3) as a geometric series 1/(1 − r) = 1 + r + r 2 + . . ., |r| < 1, and then integrating, we can obtain a series to represent the function arctan(x/a). We use the dummy variable t for the integration on [0, x] and we first write x x arctan(x/a) = a 0 dt 1 = t2 + a 2 a 0 dt 1 + (t/a)2 (4) Substituting the geometric series with r = −(t/a)2 , we find 1 arctan(x/a) = a x ∞ (−t2 /a2 )n dt = 0 n=0 (−1)n x 2n + 1 a n=0 ∞ 2n+1 . (5) The radius of convergence of this series is the same as that of the original geometric series, namely R = 1, or, in terms of x, |x/a| < 1. The series is a convergent alternating series at the right-hand end point x = a; and it can be shown that sum equals the value of arctan(1) = π/4 (as we might hope). Thus we have the nice (but slowly converging) series for π given by π 1 1 1 = 1 − + − + .... (6) 4 3 5 7 By choosing partial sums of (5) we obtain a sequence of Taylor polynomial...

...1a) Assume that the total number of instructions = 100 Based on the information given in the question, there will be 3.6 instructions of store(1.0) and load(2.6) for every 100 instructions. As per the code sequence for calculating the effective address, there will be one ADD instruction with each and every LW instruction. In the new method of calculating effective address, we are modifying the given code sequence form in such a way that there will be only one instruction instead of two instructions(ADD and LW). This results in decrease in 3.6 in the instruction count. So, the instruction count new will be 100-3.6 = 96.4 So, the ratio of instruction count (enhanced MIPS) to the instruction count (original MIPS) is 96.4/100 = 0.964 1b) speedup = Told/Tnew Assume that the old clockcycle time is t According to the question the new clockcycle time is 1.05t Told = CPI x IC(original) x Clockcycle time Told = CPI x 100 x 1t Tnew = CPI x IC(enhanced) x Clockcycle time Tnew = CPI x 96.4 x 1.05t Speedup = Told/Tnew = 0.987 From the above speedup value we can say that the original system is 1.01 times faster than the enhanced system. 2a) The depth of the pipeline depends on the maximum CPI of executing a instruction. Here, the CPI of load/store is 6. So, the pipeline will have 6 stages. 2b) Average Instruction time = CPI x IC(original) x clockcycle time In the pipelined processor, the average CPI of a pipeline will be 1 Average execution time for 100 instructions = The first five cycles...

...Mathematics (from Greek μάθημα máthēma, “knowledge, study, learning”) is the study of topics such as quantity (numbers),[2] structure,[3] space,[2] and change.[4][5][6] There is a range of views among mathematicians and philosophers as to the exact scope and definition of mathematics.[7][8] If a sequence of values follows a pattern of adding a fixed amount from one term to the next, it is referred to as an arithmetic sequence. The number added to each term is constant (always the same). The fixed amount is called the common difference, d,referring to the fact that the difference between two successive terms yields the constant value that was added. To find the common difference, subtract the first term from the second term. 1. Find the common difference for this arithmetic sequence 5, 9, 13, 17 ... | 1.
