Although introduced30 years ago, the J-matrix method has witnessed a resurgence of interest in the last few years. In fact, the interest never ceased, as some authors have found in this method an effective way of handling the continuous spectrum of scattering operators, in addition to other operators. The motivation behind the introduction of the J-matrix method will be presented in brief. The introduction of fast computing machines enabled theorists to perform cal- lations, although approximate, in a conveniently short period of time. This made it possible to study varied scenarios and models, and the effects that different possible parameters have on the ?nal results of such calculations. The ?rst area of research that bene?ted from this opportunity was the structural calculation of atomic and nuclear systems. The Hamiltonian element of the system was set up as a matrix in a convenient, ?nite, bound-state-like basis. A matrix of larger size resulted in a better con?guration interaction matrix that was subsequently diagonalized. The discrete energy eigenvalues thus obtained approximated the spectrum of the system, while the eigenfunctions approximated the wave function of the resulting discrete state. Structural theorists were delighted because they were able to obtain very accurate values for the lowest energy states of interest.

Don't worry This friendly guide explains football rules, shows you how to approach coaching, and gives you practical pointers on improving team skills and encouraging good sportsmanship. It helps you: understand football rules; develop a coaching philosophy; teach football fundamentals; run great training sessions; lead your team during a game; and, communicate effectively with parents.

Breakthroughs in nanotechnology have been coming at a rapid pace over the past few years. This was fueled by significant worldwide investments by governments and industry. But if these promising young technologies cannot begin to show commercial viability soon, that funding is in danger of disappearing as investors lose their appetites and the economic and scientific promise of nanotechnology may not be realized. Scrutinizing the barriers to commercial scale-up of nanotechnologies, the Nanomanufacturing Handbook presents a broad survey of the research being done to bring nanotechnology out of the laboratory and into the factory. Current research into nanotechnology focuses on the underlying science, but as this forward-looking handbook points out, the immediate need is for research into scale-up, process robustness, and system integration issues. Taking that message to heart, this book collects cutting-edge research from top experts who examine such topics as surface-programmed assembly, fabrication and applications of single-walled carbon nanotubes (SWNTs) including nanoelectronics, manufacturing nanoelectrical contacts, room-temperature nanoimprint and nanocontact technologies, nanocontacts and switch reliability, defects and surface preparation, and other innovative, application-driven initiatives. In addition to these technical issues, the author provides a survey of the current state of nanomanufacturing in the United States-the first of its kind-and coverage also reaches into patenting nanotechnologies as well as regulatory and societal issues. With timely, authoritative coverage accompanied by numerous illustrations, the Nanomanufacturing Handbook clarifies the current challenges facing industrial-scale nanotechnologies and outlines advanced tools and strategies that will help overcome them.

This book is a sign of its times. Each one of the chapters - papers written by European authors of various backgrounds- illustrates a departure from the style of theorizing that has been prominent in the behavioral and social sciences for most of the century. Until very recently, models for behavioral phenomena were chi~fly based on numerical representations of the objects of concern, e. g. the subjects and the stimuli under study. This was due in large part to the influence of nineteenth century physics, which played the role of the successful older sister, the one that had to be imitated if one wished to be taken seriously in scientific circles. The mystical belief that there could be science only when the objects of concern were susceptible of measurement in the sense of physics was a credo that could not be violated without risks. Another, more honor able justification was that the numerical models were the only ones capable of feasible calculations. (In fact, these models were typically linear. ) An early example of such theorizing in psychology is factor analysis, which attempted to represent the results of mental tests in a real vector space of small dimen sionality, each subject being represented by a point in that space. A dimension WaGBP interpreted as a scale measuring some mental ability. The analysis was simple, and only required an electrical desk calculator (with spinning wheels), and a suitable amount of determination.

If the North Had Won the Civil War is two books in one. The modern story follows Stonewall Jackson "Jack" Sawyer, a history professor in the Twenty-First Century Confederate States of America. Jack writes an alternate history called If the North Had Won the Civil War in the CSA, where publication of his book is a criminal offense. The story depicts a nightmarish modern-day Confederacy where any person with a drop of black blood in his veins is denied basic human rights and confined to a "Preserve." Interwoven with the story of Jack is Jack's book. This alternate history of the Civil War is written with the painstaking historical authenticity and attention to detail that Andrew Heller's fans have come to expect from him. The characters in the book-within-a-book are all taken from history, and the military tactics and strategies are based on those of the actual war. The novel is followed by an lively and informative factual essay of the Civil War. Illustrated throughout with Civil War pictures.
