Download or read book Finite Elements for Electrical Engineers written by P. P. Silvester and published by Cambridge University Press. This book was released on 1990-03-01 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: This third edition of the principal text on the finite element method for electrical engineers and electronics specialists presents the method in a mathematically undemanding style, accessible to undergraduates who may be encountering it for the first time. Like the earlier editions, it begins by deriving finite elements for the simplest familiar potential fields, and then formulates finite elements for a wide range of applied electromagnetics problems. These include wave propagation, diffusion, and static fields; open-boundary problems and nonlinear materials; axisymmetric, planar and fully three-dimensional geometries; and scalar and vector fields. A wide selection of demonstration programs allows the reader to follow the practical use of the methods. Besides providing all that is needed for the beginning undergraduate student, this textbook is also a valuable reference text for professional engineers and research students.

Download or read book Electrical Machine Analysis Using Finite Elements written by Nicola Bianchi and published by CRC Press. This book was released on 2017-12-19 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the fan motor in your PC to precision control of aircraft, electrical machines of all sizes, varieties, and levels of complexity permeate our world. Some are very simple, while others require exacting and application-specific design. Electrical Machine Analysis Using Finite Elements provides the tools necessary for the analysis and design of any type of electrical machine by integrating mathematical/numerical techniques with analytical and design methodologies. Building successively from simple to complex analyses, this book leads you step-by-step through the procedures and illustrates their implementation with examples of both traditional and innovative machines. Although the examples are of specific devices, they demonstrate how the procedures apply to any type of electrical machine, introducing a preliminary theory followed by various considerations for the unique circumstance. The author presents the mathematical background underlying the analysis, but emphasizes application of the techniques, common strategies, and obtained results. He also supplies codes for simple algorithms and reveals analytical methodologies that universally apply to any software program. With step-by-step coverage of the fundamentals and common procedures, Electrical Machine Analysis Using Finite Elements offers a superior analytical framework that allows you to adapt to any electrical machine, to any software platform, and to any specific requirements that you may encounter.

Download or read book Public Opinion written by Walter Lippmann and published by . This book was released on 2018-09-04 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: Walter Lippmann wrote his "Public Opinion" at a time when something like the 'mass media' was coming into existence. Prior to the age of electronic communication, the only mechanism for reaching large numbers of individuals was the newspapers. In World War I, he saw how opportunistic nations used the newspapers to serve their often nefarious aims. Lippmann, however, believed that in the hands of super-intelligent, disinterested, omni-benevelont 'experts, ' the 'mass media' could bring about world peace. The school system, the advent of radio, and of course, the television, were arriving or coming along shortly. Each allowed a small group of people the ability to manage a much larger group, inspiring optimism among liberals and progressives that with the right forumula, the horrors seen in World War I would never occur again. Lippmann wrote "Public Opinion" in 1922, shortly after World War I. In 1924, a certain Adolf Hitler would be spending time in jail. If this merited any mention in any newspaper, it is doubtful that no expert paid it any mind. 1939 was, after all, a long way off.

Download or read book Numerical Techniques in Electromagnetics Second Edition written by Matthew N.O. Sadiku and published by CRC Press. This book was released on 2000-07-12 with total page 764 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the availability of powerful computer resources has grown over the last three decades, the art of computation of electromagnetic (EM) problems has also grown - exponentially. Despite this dramatic growth, however, the EM community lacked a comprehensive text on the computational techniques used to solve EM problems. The first edition of Numerical Techniques in Electromagnetics filled that gap and became the reference of choice for thousands of engineers, researchers, and students. The Second Edition of this bestselling text reflects the continuing increase in awareness and use of numerical techniques and incorporates advances and refinements made in recent years. Most notable among these are the improvements made to the standard algorithm for the finite difference time domain (FDTD) method and treatment of absorbing boundary conditions in FDTD, finite element, and transmission-line-matrix methods. The author also added a chapter on the method of lines. Numerical Techniques in Electromagnetics continues to teach readers how to pose, numerically analyze, and solve EM problems, give them the ability to expand their problem-solving skills using a variety of methods, and prepare them for research in electromagnetism. Now the Second Edition goes even further toward providing a comprehensive resource that addresses all of the most useful computation methods for EM problems.

Available in PDF, EPUB and Kindle. Book excerpt: VI SOCRATES: I think that we ought to stress that we will write only about things that we have first hand experience in, in a coherent way that will be useful to engineers and other scientists and stressing the formulation without being too mathematical. We should write with integrity and honesty, giving reference to other authors where reference is due, but avoiding mentioning everybody just to be certain that our book is widely advertised. Above all, the book should be clear and useful. PLATO: I think we should include a good discussion of fundamental ideas, of how integral equations are formed, pointing out that they are like two dimensional shadows of three dimensional objects, ... SOCRATES: Stop there! Remember you are not 'the' Plato! PLATO: Sorry, I was carried away. ARISTOTLE: I think that the book should have many applications so that the reader can learn by looking at them how to use the method. SOCRATES: I agree. But we should be careful. It is easy to include many illustra tions and examples in a book in order to disguise its meagre contents. All examples should be relevant. ARISTOTLE: And we should also include a full computer program to give the reader if so he wishes, a working experience of the technique.
