Research Balfour Beatty plc - Essay Example In the year 2002,civil engineering accounted for almost 38%, building services 35,and rail engineering 27% of the total profits acquired by the organization. (Corporate Watch, 2006) Balfour Beatty, founded by George Balfour and Andrew Beatty, mechanical engineer and a charted accountant by professions respectively was initially into making streetcar lines. However, the world war –II brought the construction of streetcar lines to a halt and brought about a stalemate situation in the company. A landmark decision was taken at that point of time to expand into the civil construction arena. Balfour Beatty also played an instrumental role in the early 1920s in managing various power corporations across Great Britain into construction of a common â€Å"grid† in Britain. Balfour Beatty was acquired by BICC, a cabling company in the year 1969.Balfour Beatty was a subsidiary and accounted for more than half of BICC’s revenues. In 1999, BICC’s cabling operations were at a sagging low and the company decided to divest their cable operations. In the year 2000, BICC changed its name to Balfour Beatty plc.

Non Equillibrium Green’s Function Technique

Non Equillibrium Green’s Function Technique NON EQUILLIBRIUM GREEN’S FUNCTION TECHNIQUE USED FOR THE METAL-INSULATOR-METAL DIODES ANSHUMAN Electronics and Communication Dept. NIT Kurukshetra Abstract – In this paper theoretical analysis of NEGF method, including the transport equation and Poisson equation, is done followed by the derivation of an analytical model using NEGF tunnelling probability through any number of insulating layers. Numerical NEGF simulator are shown matching with the AF-TMM simulator results. INTRODUCTION THE STUDY OF tunnelling phenomena in Metal Insulator Metal (MIM) is an important topic for the aim of the development of rectennas for energy harvesting and infrared detectors applications. Although the interest in Metal-Insulator-Metal (MIM) diodes dates back to 1950s [1]–[4], but they attracted the attention again in the last few years due to its applications, energy harvesting [5]–[8] and infrared/terahertz detectors [9]–[11]. Earlier, various analytical expressions for the tunnelling transmission probability through MIM diodes were developed based on WKB approximation [2]–[4]. However, the WKB does not take into consideration the wave function reflections at the interface between different layers [14]. Therefore, there came the need for other models to simulate the tunnelling probability. Non Equilibrium Green Function (NEGF) [12] numerical method is one of the methods used to calculate the tunnelling transmission probability [15]–[18]. It is an accurate numerical method, but it needs long time of calculations on a PC in comparison to other analytical models. Any program used for the simulation of a device performs a solution of transport equation and â€Å"Poisson† equation [19].The transport equation gives the electron density, n(r) and the current, I for a known potential profile U(r), while Poisson equation gives the effective U(r), felt by an electron due to the presence of other electron in its vicinity. Here, in this paper the Quantum transport, Green’s functions and its various equations under non equilibrium condition are discussed and a detailed quantum mechanical modeling of the tunnelling current through MIM diodes is presented. An analytical expression for the tunnelling transmission probability is presented using the NEGF equations for any number of insulator layers between the two metals. Fig.1. Transport of electrons for single energy level device The paper is organized as follows: in Section II, the transport equations are discussed. In section III NEGF equations for MIM Diode is described in detail. The governing equations and numerical implementation of it is outlined. The material parameters used in the simulation are also summarized. GENERAL TRANSPORT EQUATION Let’s consider the model for a single device sandwiched between two metals 1and 2ION THE METAL-INSULATOR.ce of other electron in its vicinity.port and 111111111111111111111111111111111111111111, as shown in fig. 1.The device is assumed to be having a single energy level, Ô . Our first aim is to find the number of electrons, N in the device. Let Ef be the Fermi level set by the work function of the two metal contacts under the equilibrium condition. On applying the bias voltage, Vb between metal 1 and 2, the Fermi- energies of two metals gets modified to  µ1 and  µ2 respectively and given as [19]: (1) This difference in Fermi-energy gives rise to a non-equilibrium condition and hence two different Fermi-functions for the two contacts. If device is in equilibrium with metal 1, then number of electrons will be f ­1 but if it is in equilibrium with metal 2, number of electrons will be f ­2, where (2) Let and be the rate of escape of electron from device into metal 1 and metal 2 respectively. Therefore the currents I1 and I2 crossing metal1 and 2 interfaces are given as[20]: And (3) For I1 = I2 = I, we get steady-state number of electrons N and current I as: (4a) (4b) Due to the applied bias voltage one of the reservoir keeps pumping the electron trying to increase the number while the other keeps emptying it trying to lower the number. Ultimately, there is a continuous flow of current, I (eq. 4b) in the external circuit. Assuming à °Ã‚ Ã…“†¡1 > à °Ã‚ Ã…“â‚ ¬ > ÃŽ ¼2 and the temperature is low enough that f1 (ÃŽ µ) ≠¡ f0 (ÃŽ µ − ÃŽ ¼1) ≈ 1 and f2 (ÃŽ µ) ≠¡ f0 (ÃŽ µ − ÃŽ ¼2) ≈ 0, the Eq. 4b simplifies to [21]: If = (5) Eq.5 suggests that we can flow an unlimited current through this one level device if we increase, i.e. by coupling the device more and strongly to the metal contacts. But the maximum conductance of a one-level device is equal to [20], so there must be some reduction factor. This reduction is due to the broadening of the discrete level that occurs because of increased coupling of the device with the two metals. This broadened discrete level can be described by the distribution: With line-width of ÃŽ ³ and shift of level from ÃŽ µ to ÃŽ µ+à ¢Ã‹â€ Ã¢â‚¬  , where. This broadening phenomena modifies the Eqs. (4a, b) to include an integral over all energies weighted by the distribution D(E) [13]: (6a) (6b) Using algebraic manipulation Eqs. (6a, b) becomes: (7a) (7b) Where (8) (9) Till now we have discussed device with single energy level ÃŽ µ. But in practical situation (i.e. for real devices) there exist multiple energy levels. Any device, in general, can be represented by a Hamiltonian matrix, whose eigenvalues tells about the allowed energy levels. For example if we describe the device using an effective mass Hamiltonian H = then it can be represented with a (NxN) matrix by choosing a discrete lattice with N point and applying methods of finite-differences [13]. This corresponds to using a discretized real space basis. Similarly, we define self-energy matrices [∑ ­1,2] which describe the broadening and shift of energy levels due to coupling with the two metals. The required NEGF equations now can be obtained from Eqs(7a, b) by replacing scalar quantities ÃŽ µ and ÏÆ' ­1,2 with the corresponding matrices [H] and [∑ ­1,2], and is given as: , (10) , (11) The number of electrons N, in the device is replaced with the density matrix, given by: {} (12) Current is still represented by Eq. (7b). The transmission can be given as the trace of the analogous matrix quantity: (13) TRANSMISSION EQUATION FOR MIM DIODE USING NEGF EQUATIONS The 1D time-independent single-particle Schrà ¶dinger equation is given by [13]: Where, is the reduced Plank constant, ψ(x) is the electron wave-function, m is the effective mass and U(x) is the potential energy. If it is assumed that the insulator layers are divided into M grid points having uniform spacing, a, then finite difference discretization on the 1D grid is applied to Schrà ¶dinger equation Eq. (1) at each node i as follows [14]: (2) Where, represents the interaction between the nearest neighbour grid points i and i+1, Ui ≠¡ U (xi), and mi is the electron effective mass between the nodes i and i + 1. The coupling of the potential barrier to the left and right metal electrodes is taken into consideration by rewriting Eq. (1) for i =1 and i = M with open boundary conditions expressed at Metal1/Insulator and Insulator/Metal2 interfaces. So, Schrà ¶dinger equation now takes the following form [13]: (3) Where, H is the M Ãâ€" M Hamiltonian matrix of the insulator potential, I is the M Ãâ€" M identity matrix, ψ is the wavefunction M Ãâ€" 1 vector and S is M Ãâ€" 1 vector. ∑L and ∑R are the M Ãâ€" M self-energies of the left and right contacts respectively. Fig. 1. Potential of a stack of N insulator materials under applied bias voltage, Vb. Each insulator layer is characterized by a barrier height (Uj), a thickness (d j), a dielectric constant ÃŽ µ j, and an effective mass (m j). Now, under a tri-diagonal form H can be rewritten as: ∑L and ∑R are given as: The solution of Eq. (1) can be given in the terms of retarded Green’s function as where is MÃâ€"M retarded Green’s function [13]: The rate of escape of electron to either left or right metal from a given state can be taken into consideration by defining two quantities, ΓL and ΓR [14]. Hence, the tunnelling probability can now be computed as [14]: COMPARISION OF NEGF MODEL WITH OTHER MODELS A model of MIIM diode was simulated using NEGF, AF-TMM and WKB Approximation for a comparative analysis of their transmission probability vs. electron transmission energy curve. The parameter spacing, a, for the NEGF calculation was assumed equal to the hundredth of the insulator layer thickness. This was found adequate for reasonable simulation time. The effective mass was assumed equal to the free mass of the electron throughout the MIM structure. Fig.3 below shows theof the simulated MIIM of Nb/Nb2O5 (2nm)-Ta2O5 (1nm)/Nb at 0.1V of bias voltage. A complete matching between AF-TMM and NEGF results is observed. Fig.3.

Free Essays - A Lesson Before Dying :: Lesson Before Dying Essays

Ganes, Earnest J. A Lesson Before Dying. New York: Vintage Books   1993. Genre: Novel 256 pages Setting: The story is set in a small Cajun Louisiana town in the 1940’s. The setting in this story is significant because, the whole story is about how a young black boy is treated unfairly and sentenced to death because of something he did not do. It also deals with the emotions that this black boy faces because he has been treated unfairly by the white people. Major Characters: Jefferson, black boy who is accused of a crime and sentenced to death; Grant Wiggons, teacher sent to help Jefferson. After he went and obtained a college degree, Grant Wiggins goes back to live with his grandmother. Being that he is a very educated person, Grant was elected by his grandmother to try and get Jefferson to realize that he was a man and not an animal like the white people had led him to believe. Throughout the entire novel, Grant is battling this idea in his head because he doesn’t feel that even he knows what it is to be a man. He doesn’t believe that he is the right person to talk to Jefferson. But by the end of the novel, he figures out what it is to be a man. Minor Characters: Miss Emma is Jefferson’s grandmother. She is the one who had the whole idea of Grant going up to the jail and talking to Jefferson, showing him that he is a man. Tante Lou is Grant’s aunt. She is the person who raised Grant to be the good, kind person that he is. She is also the one who talked Grant into talking to Jefferson. Vivian is Grant’s girlfriend; she is Grant’s encouragement. Whatever problems he has, he always talks to her about them and she makes him feel better, and helps him through them. Summary: This story is about racism in the south and how it affects the people it concerns. It starts out with Jefferson being sentenced to death for a crime that he did not commit. He was in the wrong place, at the wrong time, and because he was black, they assumed he did it. Grant Wiggins is told to go up to the jail and convince Jefferson that he is a man. At first he doesn’t know how to make Jefferson see that he is a man, but through visiting Jefferson, talking to Vivian and witnessing things around the community, he is able to reach Jefferson, convince him that he was a man.

Tropicana Drops Package Redesign Essay -- Business Analysis

This article discusses how Tropicana redesigned their packaging and how it plans to bring back the previous version. This change was made in order to attract more customers to buy the product. Introduction The source for this article was found on New York Times online. Stuart Elliott. â€Å"Tropicana Discovers Some Buyers Are Passionate About Pacakaging†. Retrived Feburary 23, 2009. http://www.nvtimes.com/2009/02/23/business/media/23adocl.html? Why Change? Tropicana has decided to return to its orginal packaging and symbol of one of the most favorite bands of organge juice. The PepsiCo Americas Beverage division is changing their flagship product of Tropicana Pure Premium organge juice because some of the customers did not like the new design of the product. One of the worst things about the Tropicana redesign was the lost of the famous orange and straw. They described the new packaging as being† ugly†, and â€Å"resembling a generic brand†. When I first saw the Tropicana juice pacakaging, I thought that it was a store brand. Therefore I did not purchase the product because I assumed that it would not taste the same. The new design made it more difficult to distingush among the varities of Tropicana juices. A lot of the customers missed the old design which consisted of an organge with a straw in the middle. According to our text, â€Å"a firm’s external envionment consists of all the conditions and forces that affect its strategic options and define its competitive situation†. (Pearce & Robinson. 2009, pg. 12). The customers who used Tropicana felt better buying the orginal tropicana because they said that† the organge symbol meant to evoke fresh taste†. When you change the packaging of the product, most feel as though the conte... ...ny more ways to come up with new products for them to try. If customers are dissatified, it gives the company an opportunity to allow customer feedback and be able to change what they do not like about the product and to improve it. Tropicana has been around for a long time and some customers are use to drinking this kind of organge juice. I know the customers did the right thing by voicing their opinion because if they didn’t the company would think that customers were pleased with this new design when apparently they didn’t like it at all.

Second World War Essay -- American History Great Powers Essays

Second World War My generation has already witnessed a day of infamy, less than two short years ago (or so CNN tells us). My grandfather would remember a different day, a morning marked by another surprise attack on America. That ambush, said Japanese General Yamamoto, awakened a â€Å"sleeping giant.† Analysis of American foreign policy begs the question: what if the giant had spurned its peaceful slumber? Instead, the behemoth could have chosen to lumber about. Odds are that the footsteps would not have fallen lightly, the reverberations spreading across the globe- all this, only had Wilsonians been at the helm of American foreign policy. The Jacksonian tradition steered the United States to victory in the Second World War. Once lulled from the comfort of its isolationism, the Americans sealed the fate of the Axis powers. But had the Wilsonian tradition, a formidable current here at Swarthmore and among today’s democrats, directed American foreign policy leading up to and during the war, it seems likely that history would tell a different tale. As it stood in 1941, the United States was undoubtedly entrenched in the Jacksonian camp (here at Swarthmore, I can count their sympathizers on one hand). Jacksonian policies of the United States in the 1930s and 1940s proved decisive for the Allied victory, yet reflection on a reorientation of these policies toward the Wilsonian camp reveals that the Second World War could have been avoided. In this context, German domestic and foreign policy- a brutish, perverted mix of the Jacksonian and Wilsonian traditions- will then be discussed. An understanding of the Jacksonian doctrine clarifies the reasoning of the United States leading up to the war. This tradition was, and remains, stron... ...h: do we really want to provoke the Jacksonians of this world? Works Cited Bell, P.M.H. The Origins of the Second World War in Europe. 2nd edition.

Memoir

Pets in general are lovable. Of course, who doesn’t love a dog? Or a cat? A fish, maybe? But in my case, it’s different. Not because I dislike innocent animals but because I have this extreme within me since childhood. You may not believe it but what I do the love are one of the most â€Å"unloved† and feared living creatures in this world —snakes and reptiles. I don’t know what it is about these cold-blooded creatures that attracted me most but for as long as I can remember, I have always been passionate about them. Lizards arouse my curiosity while snakes give me a sense of mystery and excitement. Even as a grown up now, I can still vividly recall my first encounter with a rattlesnake which was one of the scariest experiences I ever had. It was one bright, sunny morning and we were playing in the woods. The summer heat was conducive for outdoor activities and our â€Å"gang† has gathered once again to welcome the long school break. Careless and jolly, I was only 10 then and I was chasing my ball after it was tossed away in a very secluded area. I could not even remember what game was that but I was running after the ball and as soon as I entered the isolated zone, I felt shivers in my nape which gave me the creeps. I had cold sweats just as the earth was cold and moist and there were dried, wrinkled leaves scattered all over. I moved quite slowly not knowing what’s in store in there. I looked everywhere for my ball using my telescopic vision. I was quite good in finding things and stuff. As soon as I found the ball behind a moss-filled rock, I heard this eerie hissing sound. Sensing that it might be a snake, I was agitated that I wondered where it could be hiding. I said to myself, â€Å"This is a chance of a lifetime!† I was thinking twice at first anticipating the danger it could do to me. Anti-venoms were difficult to find during those days. Nevertheless, I hesitated. Out of curiosity, I kicked the rock hard and there it was†¦a fat, healthy rattlesnake! I suppose it was taking a nap before I got there. But at that moment its eyes looked straight at mine, I knew that there was impending harm to come. My mind was flying somewhere. All I felt was fear and thrill. The rattlesnake I found was brown, about four feet long with a triangular head. The minute I saw it, I was shaking hard and I froze all over. Knowing that rattlesnakes only attacked humans when disturbed, I was reluctant to go near it. But thinking it was my only opportunity to explore and take a good look at a real one, I picked up a stick and went closer to it moving one step at a time. As soon as I was closest to it, it gave a sort of evil look at me as if it was about to bite me whole. Then I gathered all my nerves and began to strum its thick scales then lifted it up slowly. It irked! I felt great and brave. Right that moment, I thought I’d die a terrible death from a venomous snake. Then I struggled to gaze at it for a few minutes. What a beautiful sight! And that’s how I remember it. I returned it back to its place then I started moving away slowly to avoid provoking its untamed nature. When I returned to my â€Å"gang,† I proudly shared to them the wonderful yet terrifying experience with the first snake I have ever encountered. I never told my mom what I did because I knew she’d kill me for doing such a â€Å"stupid† thing as she might have called it. I never had any other close encounters with snakes after that. I actually never petted them long. I gave up my Gopher snakes soon enough after I kept them a few years ago. But being a unique pet lover, it is quite rewarding on my part especially when I hear people praise me for it. Even if only see snakes usually in cages or in the zoos now, I can always remember that one fateful day I met that rattlesnake in the wild. I will always remember how beautiful it was. My experiences with lizards were not as intense as that I’ve had with snakes probably because they are harmless and naà ¯ve. But my daily encounters with lizards were as memorable to me as that of snakes. Actually, it was quite a traumatic beginning for me. I was standing in our front porch one day when I saw this kid (I think he was younger than me at that time) playing with a lizard. It was about 4 inches long and brown in color so I assumed it was a fence lizard. It had a bluish belly though. At first, the kid was feeding it with small insects I could not identify then before I knew it, he was flipping the poor lizard up and down. I was about to approach him when the next thing I saw was he stepped on it and the lizard was squeezed like an orange fruit. There it was lying flat on the street not breathing anymore. It was a terrible event which I cannot erase from my long-term memory until now. From then on, I came to love lizards more and I collected not only fence lizards but alligator and whiptail lizards as well. When I stopped keeping snakes, my lizards remained. At present, I still have my lizards which I long to protect and care for in my own simple ways. To my mind, at least I am making a difference in the lives of these astonishing small creatures which are often neglected and unappreciated by people. It is so sad to note that in some countries which do not have strict animal rights, snakes and reptiles are ruthlessly killed even with just the sight of them, even if they did nothing to harm humans. We should realize that such acts are merely their naturally-occurring defense mechanisms. Some races made them into exotic dishes and sold at high prices. Even in zoos and animal sanctuaries, snakes and reptiles are given negative connotations which affect the impressions of people in general regarding these creatures. The media play a great role in influencing people’s opinions and generalizations about snakes and reptiles. Since time immemorial, I have never seen a film, TV show or any advertisements for that matter depicting snakes in a positive manner. Movies like â€Å"Anaconda,† â€Å"Anacondas,†   Ã¢â‚¬Å"Spasm,† â€Å"Venom,† â€Å"Snakes on the Plane,† â€Å"Rattled,† and many more all gave snakes bad images. Oftentimes, snakes are shown to represent evil and have been considered demonic symbols. How can people’s attitude towards snakes and reptiles be changed if what is being shown by entertainment is purely the dark side of these creations? It certainly takes time to alter people’s perceptions on snakes and reptiles. One of the most effective medium to begin with is education. We should be reminded that snakes and reptiles are also part of our wildlife, thus, they should be conserved and protected like any other endangered species. Children should be taught to love all animals through promoting media exposure and including conservation of wildlife in the school curriculum to instill in their minds the need to appreciate even the most dangerous creatures. This is not an easy task pursue since most learning of children are facilitated at home and most parents and guardians teach children to fear snakes and reptiles. This is the reason why massive media campaign should be done to alter our views about snakes and reptiles even at a slow pace. What is of the essence is that there should be efforts and attempts to correct the wrong impressions people have of these despised animals. While it may be true that snakes and reptiles are feared and â€Å"unloved† by most people, for me, they are wonderful creatures. Therefore, it is not true that they are feared and ‘unloved† because there are still people like me who can love them unconditionally. And I choose to remain as such as long as I have the capacity to do so.
