Energy Stabilisation of Electrostatic Accelerators (Hardcover, New): J. Takacs Energy Stabilisation of Electrostatic Accelerators (Hardcover, New)
J. Takacs
R7,448 Discovery Miles 74 480 Ships in 18 - 22 working days

Electrostatic accelerators, such as the Van de Graaf generator, are among the most established and well--developed particle accelerators. One of the key issues in the maturation of these accelerators has been the development of methods used to stabilize the energies of the particles they produce. Energy Stabilization of Electrostatic Accelerators presents a comprehensive overview of the key methods of stabilizing the energy of ions produced by electrostatic accelerators. After giving comprehensive background information on the subject, it explains the basis of high voltage generation, covering both the Van de Graaf charge transfer and the Crockcroft Walton voltage multiplier principle. This is followed by a description of the various methods used to detect the fluctuation in the energy of the accelerated ions. The later chapters describe the various ways used to stabilize the energy of the ions, gradually leading the reader to models of more complicated multi--loop stabilizers, composed from the simple models derived in the previous chapters. Some of the information on the mathematical modeling of physical phenomena applied in the stabilization has not been published before. Also featured is a whole chapter devoted to the problem of modulating the energy of the ions to a predetermined way. Energy Stabilization of Electrostatic Accelerators has been written with the accelerator designer and user in mind, but will also prove extremely useful to researchers and graduate students engaged in accelerator--based research, both pure and applied, whose interests lie in improving accelerator performance. It assumes only a basic knowledge of feedback and control system theory and Laplace transformation, which makes it readily understandable for any readers with physics and electronic engineering backgrounds.

Modern Theory of Thermoelectricity (Hardcover): Veljko Zlatic, Rene Monnier Modern Theory of Thermoelectricity (Hardcover)
Veljko Zlatic, Rene Monnier
R2,963 Discovery Miles 29 630 Ships in 10 - 15 working days

In recent years, there have been important developments in the design and fabrication of new thermoelectrics. While a decade ago, progress was mainly empirical, recent advances in theoretical methods have led to a deeper understanding of the parameters that affect the performance of materials in thermoelectric devices. These have brought the goal of producing materials with the required characteristics for commercial application a significant step closer. A search for efficient materials requires a fully microscopic treatment of the charge and heat transport, and the aim of this book is to explain all thermoelectric phenomena from this modern quantum-mechanical perspective. In the first part on phenomenology, conjugate current densities and forces are derived from the condition that the rate of change of the entropy density of the system in the steady state is given by the scalar product between them. The corresponding transport coefficients are explicitly shown to satisfy Onsager's reciprocal relations. The transport equations are solved for a number of cases, and the coefficient of performance, the efficiency, and the figure of merit are computed. State-of-the-art methods for the solution of the transport equations in inhomogeneous thermoelectrics are presented. A brief account on how to include magnetization transport in the formalism is also given. In the second part, quantum mechanical expressions for the transport coefficients are derived, following the approach by Luttinger. These are shown to satisfy Onsager's relations by construction. Three lattice models, currently used to describe strongly correlated electron systems, are introduced: the Hubbard, the Falicov-Kimball, and the periodic Anderson model (PAM), and the relevant current density operators are derived for each of them. A proof of the Jonson-Mahan theorem, according to which all transport coefficients for these models can be obtained from the integral of a unique transport function multiplied by different powers of the frequency, is given. The third part compares theory and experiment. First for the thermoelectric properties of dilute magnetic alloys, where the theoretical results are obtained from poor man's scaling solutions to single impurity models. Then it is shown that the experimental data on heavy fermions and valence fluctuators are well reproduced by the transport coefficients computed for the PAM at low and high temperature. Finally, results obtained from first principles calculations are shown, after a short introduction to density functional theory and beyond. A number of useful appendices complete the book.

Maurice N. Amutabi
R1,779 Discovery Miles 17 790 Ships in 10 - 15 working days

The book breaks new ground in understanding the role of Non-Governmental Organizations (NGOs) in Africa. The book historicizes NGOs using the Rockefeller Foundation as a case study, looking at its tripartite paradoxical roles as an agent of colonialism, globalization and development/underdevelopment. It deploys interdisciplinary devices to show how the RF projects have engaged in marginalization, patronage and 'othering' of African values and customs and the ensuing controversies. Using globalization, postmodern and postcolonial theories the book deconstructs the long-held myths about NGO inviolability, and opens ground for understanding their strengths. It interrogates sites of contestation, apprehension and possibilities that the RF has produced. Using RF projects, it looks at structures of hegemony, race, power, class and gender that the RF has created. The book illustrates the extent to which the RF has been instrumental in spreading capitalism, imperialism in economic, political, cultural and social realms through globalization. It desists from the grand narrative approach that has dominated African history in the past but instead gives agency and voice to those that have previously been marginalized.

The groundbreaking book that details the fundamentals of reliability modeling and evaluation and introduces new and future technologies Electric Power Grid Reliability Evaluation deals with the effective evaluation of the electric power grid and explores the role that this process plays in the planning and designing of the expansion of the power grid. The book is a guide to the theoretical approaches and processes that underpin the electric power grid and reviews the most current and emerging technologies designed to ensure reliability. The authors--noted experts in the field--also present the algorithms that have been developed for analyzing the soundness of the power grid. A comprehensive resource, the book covers probability theory, stochastic processes, and a frequency-based approach in order to provide a theoretical foundation for reliability analysis. Throughout the book, the concepts presented are explained with illustrative examples that connect with power systems. The authors cover generation adequacy methods, and multi-node analysis which includes both multi-area as well as composite power system reliable evaluation. This important book: - Provides a guide to the basic methods of reliability modeling and evaluation - Contains a helpful review of the background of power system reliability evaluation - Includes information on new technology sources that have the potential to create a more reliable power grid - Addresses renewable energy sources and shows how they affect power outages and blackouts that pose new challenges to the power grid system Written for engineering students and professionals, Electric Power Grid Reliability Evaluation is an essential book that explores the processes and algorithms for creating a sound and reliable power grid.
