Libros de Electricidad, página 2 de 12

This revised edition provides patient guidance in its clear and organized presentation of problems. It is rich in variety, large in number and provides very careful treatment of relativity. One outstanding feature is the inclusion of simple, standard examples demonstrated in different methods that will allow students to enhance and understand their calculating abilities. There are over 145 worked examples; virtually all of the standard problems are included.

Estos problemas de Electricidad están dirigidos a los estudiantes del primer ciclo científico de las Universidades y a la preparación para las Escuelas Superiores de Ingeniería. En vez de coleccionar un gran numero de problemas, se han elegido los mas caracteristicos desarrollando en detalle las soluciones. Estos problemas se han resuelto con todas las explicaciones necesarias, como debe hacer un estudiante en un examen, o en un concurso... lo que no se improvisa en un dia, sino que debe aprenderse junto con la materia estudiada.

Based on the latest progress in superconductivity research, the authors form a conventional theory of superconductivity and express BCS paring theory at a higher level. They especially emphasis the importance of the long-range phase coherence for the superconductivity. They also point out some misunderstandings of basic concepts about superconductivity in present textbooks and monographs. They illustrate the correct theory of the high-Tc superconductivity and the application of the high-Tc superconductors to establish a correct and detailed theory regarding this mechanism in different systems.

Este manual está dirigido especialmente a estudiantes universitarios de primer ciclo de facultades de ciencias experimentales y de escuelas técnicas, que cursen asignaturas de introducción al alectromagnetismo, pues su contenido se ajusta a la mayoria de

Muchas partes de las ciencias y la ingenier¡a (electromagnetismo, mec nica de fluidos, resistencia de materiales, etc.?) tienes grandes cosas en com£n, una de ellas es que las ecuaciones que expresan algunas de sus leyes b sicas son desde un punto de vista formal id‚nticas. Esto invita a estudiar a fondo la metodolog¡a m s adecuada para su resoluci¢n y por tanto a que los estudiantes de ciencias e ingenier¡a tengan una forma de abordar la resoluci¢n de estas ecuaciones. Es por ello que el texto que aqu¡ se presenta va claramente destinado a estudiantes de ciencias e ingenier¡a que quieren aprender a resolver problemas b sicos de electromagnetismo e incluso de otras disciplinas cuyos comportamientos matem ticos nos lleven a ecuaciones diferenciales en derivadas parciales de tipo el¡ptico. Este tipo de ecuaciones tiene una generalidad y un protagonismo suficiente como para que le dediquemos un texto como este.

Esta dirigido a los alumnos de primero de cualquiera de las titulaciones de Ingeniería Técnica Industrial y afines. Está elaborado como manual de teoría, donde se expone el programa de Electricidad y

Esta obra pretende servir de apoyo a la docencia en materias relacionadas con las vibraciones mecánicas. Se abordan diversos modelos de sistemas mecánicos desde los más simples, sistemas discretos de un solo grado de libertad, hasta otros mas complejos, sistemas continuos. Se incluyen procedimientos para la discretizacion de sistemas continuos y una introduccion al estudio de vibraciones aleatorias y medida de vibraciones.

Era opinión dominante entre los físicos de mediados del siglo XIX, claramente influenciados por el prestigio de Newton, que todo fenómeno natural era susceptible de una explicación mecanicista. La teoria electromagnetica, que culmino con los trabajos experimentales de Faraday y teoricos de Maxwell, puso en evidencia lo erroneo de tal afirmacion. Entre otras aportaciones fundamentales, surgio el concepto de campo, que juega un papel dominante en la teoria electromagnetica. Partiendo de la descripcion de los campos electrico y magnetico independientes del tiempo, que se muestran como entidades separadas, descubriremos la intima relacion existente entre ellos cuando presentan dependencia temporal. Esta relacion es tan profunda que, en realidad, podemos afirmar que son la manifestacion de una misma realidad fisica: el campo electromagnetico. Maxwell proporciono una vision global del campo electromagnetico mediante sus famosas ecuaciones y dedujo, a partir de ellas, la existencia de ondas electromagneticas.

In this work we discuss the propagation of the wave radiation focused by the axicon, and analyze optical discharges created by laser Besselian beam in gases, fluids and on solid surfaces. We consider formation processes of discharges, properties and structures of the plasma channels. Also, we describe the methods of research of Besselian beams, breakdowns, discharges and plasmas created by the beams.The optical discharge arisen under the action of the Bessel beam field Jn(r) of solid (n = 0) or tubular (n 0) configuration turns into the plasma solid or tubular cylinder (waveguide), thereof Rayleigh length being large, Zr = d2/ 1, at the diameter of the diffraction limit. While the heating pulse front is short, the breakdown wave propagates along the beam in a mode of running focus at a velocity exceeding the light speed. The channel plasma parameters at the initial stage depend on the Besselian beam intensity level and distribution. The radial expansion velocity of the plasma channel is approximately in general agreement with the theory of cylindrical strong explosion.The channel axial symmetry provides important advantage over the plasma of spherical symmetry, for it implies effective application of magnetic field. Besselian beams can be formed by electromagnetic radiation of any frequency range, as well as by wave radiation of any other nature, e.g. acoustic.The capability of the plasma parameter distribution and that of the channel structure to be varied are important for applications. Examples of beam and plasma channel applications are considered in the book.

For junior/senior-level electricity and magnetism courses.This book is known for its clear, concise, and accessible coverage of standard topics in a logical and pedagogically sound order. The highly polished Fourth Edition features a clear, easy-to-understand treatment of the fundamentals of electromagnetic theory, providing a sound platform for the exploration of related applications (AC circuits, antennas, transmission lines, plasmas, optics, etc.). Its lean and focused approach employs numerous new examples and problems. Features The book features a friendly, informal style.Focuses clearly on basic electromagnetic theory, providing a sound platform for future exploration of related applications (such as AC circuits, antennas, transmission lines, plasmas, optics, etc.). A large collection of problems includes short, highly-focused problems that are placed immediately following the relevant text section while longer/more broadly-based problems are at the end of the chapter. Features a more extensive coverage of radiation theory than most texts at this level. Zum Seitenanfang New to this Edition Edits to the entire text have clarified arguments and eliminated ambiguities. New problems and new worked examples appear throughout, while selected unsuccessful ones have been eliminated. All 450 figures have been reviewed for accuracy and updated where necessary. A new section on magnetic work helps to eliminate teachers misconception that magnetic forces do not work.The new section fully explores the actual mechanism in cases where magnetic forces are actually working. Erroneous passages have been corrected. In particular, misleading copy (specifically the treatment of hidden momentum) has been fixed. Citations of recent literature appear throughout for those who wish to pursue a particular topic in greater depth. This literature helps reinforce the point that electrodynamics is a vibrant and dynamic field, even after 150 years.
