Electromagnetics is the foundation of our electric technology. It describes the fundamental principles upon which electricity is generated and used. This includes electric machines, high voltage transmission, telecommunication, radar, and recording and digital computing. Numerical Methods in Electromagnetism will serve both as an introductory text for graduate students and as a reference book for professional engineers and researchers. This book leads the uninitiated into the realm of numerical methods for solving electromagnetic field problems by examples and illustrations. Detailed descriptions of advanced techniques are also included for the benefit of working engineers and research students. Comprehensive descriptions of numerical methods In-depth introduction to finite differences, finite elements, and integral equations Illustrations and applications of linear and nonlinear solutions for multi-dimensional analysis Numerical examples to facilitate understanding of the methods Appendices for quick reference of mathematical and numerical methods employed

Positioning itself at the common boundaries of several disciplines, this work provides new perspectives on modern nanoscale problems where fundamental science meets technology and computer modeling. In addition to well-known computational techniques such as finite-difference schemes and Ewald summation, the book presents a new finite-difference calculus of Flexible Local Approximation Methods (FLAME) that qualitatively improves the numerical accuracy in a variety of problems.
The only one-stop reference to design, analysis, and manufacturing concepts for power devices utilizing HTS. High temperature superconductors (HTS) have been used for building many devices for electric grids worldwide and for large ship propulsion motors for the U.S. Navy. And yet, there has been no single source discussing theory and design issues relating to power applications of HTS—until now. This book provides design and analysis for various devices and includes examples of devices built over the last decade. Starting with a complete overview of HTS, the subsequent chapters are dedicated to specific devices: cooling and thermal insulation systems; rotating AC and DC machines; transfor...
This book explores the growing phenomenon of online news from a variety of perspectives, identifying trends in online news and presenting a collection of original research investigations about the newest medium of mass communication.
This book comprehensively examines the relationship between literature and sculpture in the work of W. B. Yeats, drawing on extensive archival research to offer revelatory new readings of the poet. The book traces Yeats's literary and critical engagement with Celtic Revival statuary, publicmonuments in Dublin, the coin designs of the Irish Free State, abstract sculpture by the Vorticists and modernists, and a variety of carvings, decorative sculptures, and objets d'art. By charting Yeats's early art school education in Dublin, his attempts to raise funds for public monuments in thecity, and to secure commissions for his favourite sculptors, the book documents a lifelong interest in the plastic arts. New and original readings of Yeats's poetry, drama, and prose criticism emerge from this concertedly inter-arts and interdisciplinary study.
John Sheppard lived in Maryland probably by the late 1600s. He may have been the son of John Sheppard and grandson of Robert Sheapheard (ca. 1645-1686) of the Barbados. His grandson, John Sheppard (1737-1827), son of John Sheppard (b. ca. 1700) was probably born at Fredericktown, Cecil County, Maryland. He married Mary Ann Hudson, ca. 1773. They had twelve children, 1775-1804, all born in Fredericktown. The family migrated to Belmont County, Ohio, in 1812. Descendants lived in Ohio, Illinois, Iowa, Missosuri, Nebraska, Colorado, California and elsewhere.

In Finite Element Analysis of Electrical Machines the author covers two-dimensional analysis, emphasizing the use of finite elements to perform the most common calculations required of machine designers and analysts. The book explains what is inside a finite element program, and how the finite element method can be used to determine the behavior of electrical machines. The material is tutorial and includes several completely worked out examples. The main illustrative examples are synchronous and induction machines. The methods described have been used successfully in the design and analysis of most types of rotating and linear machines. Audience: A valuable reference source for academic researchers, practitioners and designers of electrical machinery.
