Download or read book The J P Transformer Book written by A. C. Franklin and published by Elsevier. This book was released on 2016-10-12 with total page 831 pages. Available in PDF, EPUB and Kindle. Book excerpt: The J&P Transformer Book, 11th Edition deals with the design, installation, and maintenance of transformers. The book contains technical information, tables, calculations, diagrams, and illustrations based on information supplied by transformer manufacturers and related industries. It reviews fundamental transformer principles, the magnetic circuit, the characteristics of, and general types of transformers. The text contains tables showing the information that should be given to the transformer manufacturer to be used as a basis in preparing quotations. Transformer designs include three important distinct circuits to minimize losses: the electric, the magnetic, and the dielectric circuits. The book emphasizes that the maximum efficiency of any transformer occurs at the load at which the iron loss equals the copper loss. The text also discusses how the maximum overall operating economy of transformer substations, especially those with several transformers operating in parallel, can be effected by reducing the total transformation losses to a minimum under all loading conditions. The book is an essential reference for architects, system planners, or electrical engineers concerned with design, installation, and maintenance of transformers. It can also prove useful for electrical engineering students.

Download or read book A Course in Arithmetic written by J-P. Serre and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is divided into two parts. The first one is purely algebraic. Its objective is the classification of quadratic forms over the field of rational numbers (Hasse-Minkowski theorem). It is achieved in Chapter IV. The first three chapters contain some preliminaries: quadratic reciprocity law, p-adic fields, Hilbert symbols. Chapter V applies the preceding results to integral quadratic forms of discriminant ± I. These forms occur in various questions: modular functions, differential topology, finite groups. The second part (Chapters VI and VII) uses "analytic" methods (holomor phic functions). Chapter VI gives the proof of the "theorem on arithmetic progressions" due to Dirichlet; this theorem is used at a critical point in the first part (Chapter Ill, no. 2.2). Chapter VII deals with modular forms, and in particular, with theta functions. Some of the quadratic forms of Chapter V reappear here. The two parts correspond to lectures given in 1962 and 1964 to second year students at the Ecole Normale Superieure. A redaction of these lectures in the form of duplicated notes, was made by J.-J. Sansuc (Chapters I-IV) and J.-P. Ramis and G. Ruget (Chapters VI-VII). They were very useful to me; I extend here my gratitude to their authors.

Download or read book A Concise Course in Algebraic Topology written by J. P. May and published by University of Chicago Press. This book was released on 1999-09 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Algebraic topology is a basic part of modern mathematics, and some knowledge of this area is indispensable for any advanced work relating to geometry, including topology itself, differential geometry, algebraic geometry, and Lie groups. This book provides a detailed treatment of algebraic topology both for teachers of the subject and for advanced graduate students in mathematics either specializing in this area or continuing on to other fields. J. Peter May's approach reflects the enormous internal developments within algebraic topology over the past several decades, most of which are largely unknown to mathematicians in other fields. But he also retains the classical presentations of various topics where appropriate. Most chapters end with problems that further explore and refine the concepts presented. The final four chapters provide sketches of substantial areas of algebraic topology that are normally omitted from introductory texts, and the book concludes with a list of suggested readings for those interested in delving further into the field.

Download or read book Temple Boys written by Jamie Buxton and published by Roaring Brook Press. This book was released on 2015-02-10 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Jerusalem, year zero. Flea belongs to a gang of teenage vagrants living in the shadow of the Temple, with no family and no home, living on their wits and what they can beg or steal. The city is crowded with visitors for Passover and governed by an uneasy alliance between the Temple priests and the occupying Roman army, bringing talk of miracles and revolution. Flea and his comrades latch onto the newcomer in the hope that he'll offer them a secure home. As events accumulate and powerful forces gather around the Magician, Flea notices rumblings of discontent among his followers, and finds himself torn between one of them—the protective Jude, who employs Flea to run errands—and a brutal Roman spy determined to uncover the Magician's plans. Is the Magician the savior he claims to be, or a fraud? Does Flea hold the fate of the Magician—and possibly the world—in his hands, as he begins to believe? Temple Boys vividly conjures up ancient Jerusalem and the Biblical era and boldly re-imagines the western world's most famous story from the point of view of a teenage boy.
