This book provides a new understanding of the large amount of experimental results gained in solid state physics during the last seven decades. For more than 160 different materials, data analyses shown in terms of atomistic models (Hamiltonians) have not provided a quantitatively satisfactory description of either excitation spectra or dynamic properties. Instead, the experimental evidences have elaborated that field theories are necessary. However, most experimentalists are not familiar with field theories, and realistic field theories of magnetism are absent.The book illustrates in an empirical way the elements of future field theories of solid state physics with special emphasis on magnetic materials. In contrast to the many available textbooks on quantum field theories that emphasize more on algorithmic formalities rather than referring to the experimental facts, the approach in this book is pragmatic instead of abstract theoretic. This methodical concept considerably facilitates experimentalists to get acquainted with the basic ideas of field theories, even if a ready field theory is not provided by this experimental study._,

I was curious about black holes and the jets and searched for information. This is my version of how black holes creates jets and it is the same mechanism that produces sunspots on the Sun. The jets are powered by the rotation and that energizes the magnetic forces of the black hole and of the Sun. I provide simple calculations for these forces. It is not based on theories but standard physics available in high school and college books._,

Surface ship and submarine magnetic field signatures have been exploited for over 80 years by naval influence mines, and both underwater and airborne surveillance systems. The generating mechanism of the four major shipboard sources of magnetic fields is explained, along with a detailed description of the induced and permanent ferromagnetic signature characteristics. A brief historical summary of magnetic naval mine development during World War II is followed by a discussion of important improvements found in modern weapons, including an explanation of the damage mechanism for non-contact explosions. A strategy for selecting an optimum mine actuation threshold is given. A multi-layered defensive strategy against naval mines is outlined, with graphical explanations of the relationships between ship signature reduction and minefield clearing effectiveness. In addition to a brief historical discussion of underwater and airborne submarine surveillance systems and magnetic field sensing principles, mathematical formulations are presented for computing the expected target signal strengths and noise levels for several barrier types. Besides the sensor self-noise, equations for estimating geomagnetic, ocean surface wave, platform, and vector sensor motion noises will be given along with simple algorithms for their reduction._,

This book provides a systematic and self-consistent introduction to the nonlinear continuum mechanics of solids, from the main axioms to comprehensive aspects of the theory. The objective is to expose the most intriguing aspects of elasticity and viscoelasticity with finite strains in such a way as to ensure mathematical correctness, on the one hand, and to demonstrate a wide spectrum of physical phenomena typical only of nonlinear mechanics, on the other.A novel aspect of the book is that it contains a number of examples illustrating surprising behaviour in materials with finite strains, as well as comparisons between theoretical predictions and experimental data for rubber-like polymers and elastomers.The book aims to fill a gap between mathematicians specializing in nonlinear continuum mechanics, and physicists and engineers who apply the methods of solid mechanics to a wide range of problems in civil and mechanical engineering, materials science, and polymer physics. The book has been developed from a graduate course in applied mathematics which the author has given for a number of years._,

This book introduces the finite element and boundary element methods (FEM & BEM) for applications to quantum mechanical systems. A discretization of the action integral with finite elements, followed by application of variational principles, brings a very general approach to the solution of Schroedingers equation for physical systems in arbitrary geometries with complex mixed boundary conditions. The variational approach is a common thread through the book andis used for the improvement of solutions to spectroscopic accuracy, to adaptively improve finite element meshs, to develop a time-dependent theory, and also to generate the solution of large sparse matrix eigenvalue problems. A thorough introduction to BEM is given using the modelling of surface plasmons,quantum electron waveguides, and quantum scattering as illustrative examples. The book should be useful to graduate students and researchers in basic quantum theory, quantum semiconductor modeling, computational physics, mathematics and chemistry.

This book is a must read for everyone interested in the future role and direction of science. It begins with the description of the new discoveries made at the turn of the previous century, which have culminated in the scientific knowledge we have today.The book then discusses the fundamental constants of Nature and how they inter-relate and how they may have come to be what they are. This second book compliments and adds a vast new tranche of knowledge to Book I of the series, but is at the same time entirely readable in its own right. As it chronicles the development of modern science it opens a new window on our undestanding of science at the most fundamental level of knowledge._,

This volume is a compilation of new results and surveys on the current state of some aspects of the foliation theory presented during the conference &ldquo,FOLIATIONS 2012&rdquo,. It contains

El uso de modelos lineales para resolver problemas de optimización en diversos campos científicos e industriales es una práctica habitual desde hace muchos años. Podemos ver aplicaciones de ello, por ejemplo, en casos como la expansion de una empresa en una nueva region y la decision de la ubicacion de sus nuevos almacenes con los costes adecuados, el diseño optimo de las rutas de unos camiones de reparto, la estimacion de la cantidad de productos que debemos fabricar segun la demanda y los recursos disponibles, o la elaboracion del horario de clases en un centro educativo sin solapamientos de aulas o examenes. Este libro ofrece una vision practica del proceso de formulacion de modelos lineales, desde los pasos iniciales con los modelos mas sencillos a modelos mas complejos: Se indican los pasos que deben seguirse para formular un modelo. Se discuten en profundidad los modelos clasicos, el uso de variables binarias, los modelos estocasticos, y la optimizacion multiobjetivo. Se comentan las mejores practicas. Incluye 71 ejercicios originales, todos con soluciones comentadas, para reforzar los conceptos desarrollados, asi como otros 39 ejercicios complementarios de caracter mas avanzado. Se presenta en detalle el uso de distinto software de optimizacion de acceso libre, con el fin de facilitar al lector la resolucion de los modelos formulados.
