...1 The Pit and the Pendulum By Edgar Allan Poe I WAS sick—sick unto death with that long agony; and when they at length unbound me, and I was permitted to sit, I felt that my senses were leaving me. The sentence—the dread sentence of death—was the last of distinct accentuation which reached my ears. After that, the sound of the inquisitorial voices seemed merged in one dreamy indeterminate hum. It conveyed to my soul the idea of revolution—perhaps from its association in fancy with the burr of a mill-wheel. This only for a brief period, for presently I heard no more. Yet, for a while, I saw—but with how terrible an exaggeration! I saw the lips of the black- robed judges. They appeared to me white—whiter than the sheet upon which I trace these words—and thin even to grotesqueness; thin with the intensity of their expression of firmness—of immovable resolution—of stern contempt of human torture. I saw that the decrees of what to me was Fate were still issuing from those lips. I saw them writhe with a deadly locution. I saw them fashion the syllables of my name; and I shuddered because no sound succeeded. I saw, too, for a few moments of delirious horror, the soft and nearly imperceptible waving of the sable draperies which enwrapped the walls of the apartment. And then my vision fell upon the seven tall candles upon the table. At first they wore the aspect of charity, and seemed white slender angels who would save me; but then, all at once, there came a most deadly nausea over...

...Ron Ramos Art History/ Prof. Baum November 12, 2013 Midterm Follow-Up Assignment The Descent Into Hell by Duccio is significant as a painting because it shows the symbolic power of Christ over Satan as he sets his forefathers free from Limbo. Being in Purgatory, the souls in this place are sinned cannot move into Heaven, but Christ’s frees them and cleanses them. The technical characteristics of the painting would categorize it as Early Italian Renaissance, but has traces of Byzantine art as seen by the gold shine on Christ's robe. Above Christ’s head is a clear definition of a golden halo and represents his holiness as the son of God. The people painted in the image have shape and proportion underneath the draped clothing giving it a sense of scale and proportion. This is a characteristic that the Southern Italian artists uses due to their interest in the human anatomy. The perspective of the image is flipped up which is an attempt to giving dimension to the figures, but instead the illusion is indicated by stacked figures. Although, the doorway that Christ busted down shows the inner curves which gives the impression of the door’s dimension. By opening the cave, it allows for more space in the painting. The Moneylender and his Wife by Massys depicts a scene of a man occupied on weighing pearls, jewels, and coins on the table in front of him and this action is distracting his wife from reading a book. The two figures are symmetrically framed in the painting focusing...

...MOD 3 LOB 4: Interpret performance speeds and performance specifications for various aircrafts. Link: http://www.pilotfriend.com/aircraft%20performance/acft_list.htm When I started searching for a website I wanted to find one that had a large database of base with a good amount of specifications on each of them. The first site I had found was risingup.com but then I saw that somebody had already used that. So I continued my search and that brought me to pilotfriend. Their database of companies has 72 planes within it and when you click on each manufacturer it brings up all the models that they have specifications on. You can explore all the different models from each manufacturer. When you click on a specific company it comes up with a brief history on them and how the company got started. When you click on a specific model of plane they also give you a brief history on the plane and how it originated. They also include a few color photos, both inside and outside the plane. The performance specifications that they give all include horsepower, top speed, cruising speed, stall speed, gross weight, empty weight, fuel capacity and range. They also include ground rolls both normal and over a 50ft obstacle for both takeoff and landing. The information also includes the rate of climb and the ceiling for the aircraft. The one thing that I didn’t really like about this website is that it is mostly privately flown aircraft and not commercial liners. Other than that...

...The film the descent uses a range of shots, sound, editing and symbolisation to create an ominous atmosphere; in effect this makes the horror aspect in the film really stand out as it leaves the viewer deciding what happens in specific parts of the film, which all ties in with the films ending. This all makes the film very subjective and leaves much of the opening scenes open to interpretation which is very enticing for a horror movie. The films opening sequence contains many things which symbolise the events in the movie and starts to define what genre the movie is, because the music is fairly ambient and deep suggesting danger which implies it’s a horror or a thriller movie. When the opening credits appear light effects illuminate the names in a circle like manner, only showing only parts of the credits. The part of the view is cut because it cleverly foreshadows the events to come in the film; the illuminating light implies the flash lights the crew hold and the cut of view of the credits suggest that they wont be able to see everything down in the caves. The opening shot is a long shot of the trees and the sky to show the isolation as well as being a clear representation of Mise-en-scène because everything in the shot is well thought out and crafted; you can see more things than what the obvious may just suggest, because there is a contrast between light and dark (sky and the trees) which symbolises a barrier between good and bad (binary opposites). The trees also foreshadow...

...Steepest Descent Direction in Optimization - Application and Algorithm Hemanand. T Department of Chemical Engineering, St. Joseph’s College of Engineering, Chennai – 600 119 Abstract: An analytical solution to identify the minimum value of a function used for optimization based on steepest descent technique was extensively discussed with applications in a process. The properties of gradient vector, the oscillation of function values and overshoot were analyzed in a function for the search of minimum. The best step size in each iteration was found by conducting a one-D optimization in the steepest descent direction. The five steps in the algorithm for steepest descent direction were done for the effective search for the minimum included (i) estimate of a starting design and set the iteration counter, (ii) selection of a convergence parameter, calculation of the gradient of function f(x) at the point, (iii) then stop the iteration process at the minimum point, otherwise, search for minimum by next iteration, (iv) calculation of step size to minimize and (v) updation of the design with the new values which yield minimization of an optimization process. Keywords: Gradient Vector, Overshoot, One-D optimization, Convergence Parameter, Oscillation. 1. Introduction: In mathematics, optimization, or mathematical programming, refers to choosing the best element from some set of available alternatives. In the simplest case, this means solving problems in which one...

...Angela Bacon Reflection Questions 3 August 22, 2012 ANTH 103 Bilateral Kinship and unilineal descent groups are two different types of kinship forms used across the world. They can be similar in a lot of ways but they have a few major differences. Bilateral kinship does not have a descending family chain. Instead they start with "ego" which is the person who's life the perspective is taken. This is where the group starts in this type of kinship. This is extremely useful when you are living with a nuclear mobile family, and usually includes neolocal residence. The group then continues upward(backwards) to create a family tree, thus creating a family kindred group. On the other hand there is descent groups. Which start with one person who is usually no longer living and descends downward(forward) in time to whomever is biologically connected to the starting person. It is usually unilineal which means it only includes one side of the family to form the group instead of both. It is either matrilineal or patrilineal depending on the society you are living in. Descent groups have 2 distinct laws. The first is that it has to be a public or recognized social entity and it requires a direct lineal descent from a specified ancestor. All members of the group must always be related to the specified person. It can be either a lineage descent group, it can't go back further than 10 generations. Or it can be a Clan. Where several linked lineages gather to...

...Kinship is a culture’s way of establishing and recognizing the relationships between a family or group of people. It can define their roles, obligations, interactions between each other, and the rights among the group. According to Chegg.com, “Kinship and family ties may be defined through genetic relationships, adoption, or other ritualized behavior such as marriage and household economies. Kinship systems range in size from a single, nuclear-family to tribal or intertribal relationships” (2014). There are many different varieties of kinship and how they are addressed within many cultures. There are six different types of kinship in anthropology (Schwimmer, 2001). The two cultures being addressed in this essay are the Crow kinship and the Iroquois kinship. The Crow, also called the Absaroka or Apsaalooke, are a tribe of Native Americans who historically lived in the Yellowstone river valley. Women within these tribes have a highly significant role (Crystallinks.com, 2012). The Crow people are of a matrilineal line. They are a matriarchal tribe and in marriage the husbands moving in with the wife’s family. Following the matrilineal line, Crow kinship further addresses the women within the family. Relatives in the kinship diagram on the mother’s side have descriptive terms whereas the father’s side has more classificatory terms. A relatively distinctive note in the Crow kinship that is different from other kinship disgrams is that they do not distinguish between generations...

...A project reported submitted in partial fulfillment of the requirements of the course EEL6503: Spread Spectrum and CDMA, Fall 2001 Submitted by Arun Avudainaygam LINEAR AND ADAPTIVE LINEAR MULTIUSER DETECTION IN CDMA SYSTEMS Project Website: http://arun-10.tripod.com/mud/mud.html SECTION 0 Introduction Multiuser detection is a technology that spawned in the early 80’s. It has now developed into an important, full-fledged field in multi-access communications. Multiuser Detection (MUD) is the intelligent estimation/demodulation of transmitted bits in the presence of Multiple Access Interference (MAI). MAI occurs in multi-access communication systems (CDMA/ TDMA/ FDMA) where simultaneously occurring digital streams of information interfere with each other. Conventional detectors based on the matched filter just treat the MAI as additive white gaussian noise (AWGN). However, unlike AWGN, MAI has a nice correlative structure that is quantified by the cross-correlation matrix of the signature sequences. Hence, detectors that take into account this correlation would perform better than the conventional matched filter-bank. MUD is basically the design of signal processing algorithms that run in the black box shown in figure 0.1. These algorithms take into account the correlative structure of the MAI. 0.1 Overview of the project This project investigates a couple of different approaches to linear multiuser detection in CDMA systems. Linear MUDs are detectors that...

...superiority and dominance. This is also visible from the gossip and talking I was a part of in the first day of my fieldwork, when I helped in the kitchen. Women do not see their men superior to them, but are bound by social standards and relations to respect the social hierarchy that is embedded in their culture. When talking of Slava, the Serbs kept the tradition from patriarchal system, the patrilineal descent. Slava is passed on from father to son, and even though the rules of inviting people to Slava are free in practice, in theory they are quite strict. It is a rule that only male members of the clan can attend their, e.g. father’s Slava, because the women who married away, his daughters, no longer hold his last name, and therefore that Slava is no longer theirs to celebrate. Since, in this case, kinship is recognised through the father, every member of the lineage has kinship obligations towards a limited number of relatives, notably close male agents (Eriksen, 2010). Patrilineal systems are capable of concentrating all valuable resources in a single principle, through descent through the agnatic line: succession, inheritance, property rights, place of residence (Eriksen, 2010). In case of Slava, the son that continues to live in his parents’ house – place of residence and property rights as well as inheritance. This son also inherits his father’s Slava and the family patron, and with that the title of the head of the house and a higher place in kinship hierarchy, thus establishing...

...All societies across the universe have kinship. Some privileged cultural practices have been followed by these societies through ages regardless of the biological rules of sexual relations which ensure that the life span of these kinships is continuous through birth by human beings. (Robert Parkin 1997). Anthropology defines kinship as the connection that exists between human beings by either blood, through adoption or even by marriage. Anthropology does not view kinship in a biological manner but biology on the other hand studies it in the physical manner. The terms pater and mater are used to refer mother and father in anthropology studies whilst in biology the terms genitor and gentrix are used. Every newborn by is said to be recognized to have relations to at least one of his parent by the fact of his birth. Kinship is used to organize members of the society into different categories, roles and various social groups, based on either parentage, marriage or other types of relationship, (Schneider 2005). Inheritance rights are customarily based on how close kinship relationships are and thus, used to transmit property and status from one generation to another. In some cases kinship might be extended through relations not from the same bloodline in the kinship universe. This is what is termed as fictive kinship. The most common used example is where by you’ll get one has godparents who are not his real parents. Some will have aunts and uncles whom they call guardians and they...

With the steepest descent method, dk = − f (xk ). Assume Q = QT , so f (x) = Qx and f (x + y) = f (x) + xT Qy + f (y). Thus f (xk+1 ) = f (xk ) + αk (dk )T Qx + f (αk dk ) = f (xk ) − αk ||dk ||2 + (αk )2 f (dk ) [1] This allows us to rewrite the middle term of [GR] as follow: σ ≤ −1 + αk f (dk )/||dk ||2 ≤ 1 − σ. That is, σ − 1 ≤ −αk f (dk )/||dk ||2 ≤ −σ; so we can rewrite [GR] as σ||dk ||2 (1 − σ)||dk ||2 ≤ αk ≤ f (dk ) f (dk ) Since σ ≤ 1/2, we have σ(1 − σ) ≥ σ − σ 2 + 2σ − 1 = σ − (1 − σ)2 Since Q = QT obtain [3] [2] 0, we may appl the Kantorovich inequality (to dk ) and 16M m ||dk ||4 [(dk )T dk ]2 = ≥ k )f (xk ) 1 k T k 1 k T −1 k f (d (M + m)2 [(d ) Qd ] [(d ) Q d ] 2 2 Putting the numbered results together, [4] we have as we were to prove....

...Hamlet’s Unwilling Descent into Madness William Shakespeare’s Hamlet contains many instances when a problem of interpretation allows for different stances, but perhaps one of the most prominent questions is Hamlet’s descent into madness and to what degree he controls this madness or if it consumes him. This question is of great importance because it allows the reader to either justify or condemn Hamlet’s actions. In the 1990 Kevin Kline version of Hamlet, Hamlet’s interactions with others and his numerous soliloquies show that his madness is not an act; rather, he cracked under the extreme circumstances of his surroundings. Losing his father and seeing his mother marry his uncle within a few short months took an uncontrollable toll on Hamlet. His heightening emotions and increasing violence show that the film takes the stance that Hamlet cannot control his actions as he succumbs to insanity rather than someone in control of their action. Different versions of Hamlet take many stances on this issue from depicting Hamlet as a plotting mastermind to a man spiraling hopelessly out of control. This film is sympathetic to Hamlet’s plight as it shows his steady and unwilling descent into madness. The numerous violent incidences with his family and his dark soliloquies depict Hamlet as a man lost to his madness. By focusing on his relationships with others, the viewer can see that the interpretive stance does not place the blame on Hamlet but rather his circumstances. For example...
