Digital protection is based on the use of computers in power line relaying. Since the late 1960s, digital devices and techniques have been applied to almost all new protection schemes. Today the technology is moving towards standardised hardware platforms; at the software level, however, there remains a huge variety in approaches and protection algorithms.

This book provides a broad perspective of vacuum switchgear drawn from the author's many years of experience in this field. Allan Greenwood describes the development of the technology from the earliest beginnings to the most recent designs now on offer by leading companies around the world. The book starts with a solid foundation in the physics of the vacuum arc, in vacuum breakdown and in the fundamentals of current interruptions in vacuum.

Название: Energy Limits in Computation: A Review of Landauer’s Principle, Theory and Experiments

Год: 2018
Формат: EPUB, PDF
Размер: 21 Мб
Язык: английский / English

This book is a single-source reference to the issues involved in the Landauer principle, which has gained new prominence recently, due to the large amount of heat generated by today’s computers. If Landauer’s principle is correct, there may be ways to build computers that dissipate far less power (corresponding to heat generated) than today’s computers. This book brings together all sides of the discussions regarding Landauer’s principle, both theoretical and experimental, empowering readers to gain better understanding of dissipation in computation, and the limits if any to progress in computation related to energy dissipation. It represents the best and most thorough examination of the important issue of Landauer’s principle that is available in one volume.

Fundamentals of Structural Analysis introduces, engineering and architectural students, to the basic techniques for analyzing the most common structural elements, including: beams, trusses, frames, cables, and arches. The content in this textbook covers the classical methods of analysis for determinate and indeterminate structures, and provides an introduction to the matrix formulation on which computer analysis is based. Although it is assumed that readers have completed basic courses in statics and strength of materials, the basic techniques from these courses are briefly reviewed the first time they are mentioned.

Рассмотрены основные закономерности поведения открытых физико-химических систем при значительных отклонениях от равновесия. Большое внимание уделено вопросам неравновесной термодинамики, образованию диссипативных структур. Представлены основы математического описания процессов в неравновесных системах и анализа устойчивости конечных состояний нелинейных систем. Приведены примеры использования методов неравновесной термодинамики при решении задач, связанных с поведением гетерогенных металлических систем в различных внешних условиях.
