produced by the induced voltage differences between parallel strands in a bar that cause high ohmic losses in high power synchronous generators. In this paper, three different cases are assumed for the armature end winding structure, and a 3-D finite element model is adopted to calculate the effectiveness and resultant losses of these cases. As mentioned later, by the use of an appropriate transposition in slot area, both main and leakage fluxes inside the machine are the same for all transposed strands
had come as close as possible to analyzing real world structures. Looking back I realize, I had learned great tools for structural analysis, but my "tool box" was still inadequate. I lacked a very important tool: finite element analysis. According to my professor, finite element analysis has revolutionized structural analysis. Although I liked my classes, my internship experiences really confirmed my interest in structural engineering. While working at Caltrans as a student volunteer, I

The Modeling of Salt Water Intrusion What is Salt Water Intrusion? Salt water intrusion, or encroachment, is defined by Freeze and Cherry (1979) as the migration of salt water into fresh water aquifers under the influence of groundwater development. Salt water intrusion becomes a problem in coastal areas where fresh water aquifers are hydraulically connected with seawater. When large amounts of fresh water are withdrawn from these aquifers, hydraulic gradients encourage the flow of seawater
4.1 INTRODUCTION Structural analysis is a process to analyze a structural system to predict its responses and behaviors by using physical laws and mathematical equations. The main objective of structural analysis is to determine internal forces, stresses and deformations of structures under various load effects. In this chapter, the structural plan is taken and it is designed in the sap2000 software by taking the center line diagram and firstly a basic ground level is designed and

I have a great urge towards pragmatic industrial work environment and therefore I wish to pursue graduation study. I pen down this statement of purpose to describe my educational background and career objectives that motivated me to pursue under graduate in Mechanical Engineering. Right from the age of 6years i.e. from my second standard, I have keen interest in mathematics
In the current project, the blade structure is analyzed mainly on the four following aspects mentioned below: Analysis of maximum strength Stability analysis(buckling) Deflection analysis( to prevent blades from striking the tower) Analysis with different cores to check the stiffness Besides, fatigue failure analysis is also included in the real field testing. The first process in designing the wind turbine involve the calculation of the various loads expected to act on the blade surface during
Introduction 1.1 History of Composite Materials There were three principal driving forces that led to the interest and investment in composite materials in the world such as the designer's demand for lower weight and higher rigidity for aerospace structures, electronics, and other applications. At the beginning the 20th century composite structure materials did give a potential to meet these structural requirements of these various applications. Although composite materials had been known in various

material properties, geometry and the desired output. here HFSS will automatically generate an efficient ,accurate and appropriate mesh to solve the problem using the proven finite element method. The core of the program HFSS is based on the finite element method (FEM) (its practical application often known as finite element analysis (FEA)) where it is a numerical technique for finding approximate solutions to partial differential equations (PDE) and their systems, as well as (less often) integral
Review Context Freeform surfaces prevail in contemporary architecture. Over the past two decades there has been a surge in the use of smooth, curved surfaces, which can be attributed to improvements in 3D modelling techniques and advances in finite element analysis. The complex geometries, examples of which can be seen in the Figure ? below, pose challenges in developing a feasible building envelope using conventional building materials such as steel and concrete. This has therefore created a need
Design and Manufacturing. Out of my strong conviction that knowledge of computers is a prerequisite in today’s research, I’ve gained a special predilection towards Computer-Aided Design. This opened up a realm of possibilities in the field of Finite Element Analysis that I never imagined in my life. These courses have helped me build a strong foundation in mechanical engineering and laid the necessary groundwork to pursue graduate studies. Right from the second year, I was preparing myself by working

I want to be a professional programmer. Although my major study was mainly focused on engineering and mathematics, I had developed a solid interdisciplinary background in the college. When I was solving a problem, I always tried to come up my solutions from different angles. Through coursework, club activity and research, I began realizing the significance of computer science. My broad interests gradually concentrated on algorithm design and robotics. I believe I can achieve the master degree and
should be extended to the concepts of element and set. The relationalization of the concepts of element and set means that in the final analysis the World exists as an indivisible whole, not as a set (of one or another kind of elements). Therefore, we have to describe quantum systems in terms of potentialities and probabilities: since quantum systems cannot be analyzed completely into sets of elements, we can speak only of the potentialities of isolating elements and sets within their structure.

roadside safety structures and other vehicles, deforming under the impact. The DYNA3D program uses a technique called the finite-element method where a grid is superimposed on the frame of a car dividing the car into a finite number of small pieces or elements. The grid is then entered into the program along with data describing the specifications of the materials making up each element such as density, elasticity, etc. While reading the effect of a head-on collision on the structure of the car, the data
Elliptic Curve Cryptology What and Why of ECC? Elliptic curve cryptography (ECC) is a public key cryptography technique by making use of elliptic curve properties and their algebraic structure of over finite fields. It is one of the efficient ways of providing encryption of cryptographic keys. Elliptic curves as algebraic/geometric entities have been studied extensively for the past 150 years, and from these studies has emerged a rich and deep theory.
