A step-by-step guide to parallelizing cem codes The future of computational electromagnetics is changing drastically as the new generation of computer chips evolves from single-core to multi-core. The burden now falls on software programmers to revamp existing codes and add new functionality to enable computational codes to run efficiently on this new generation of multi-core CPUs. In this book, you'll learn everything you need to know to deal with multi-core advances in chip design by employing highly efficient parallel electromagnetic code. Focusing only on the Method of Moments (MoM), the book covers: In-Core and Out-of-Core LU Factorization for Solving a Matrix Equation A Parallel MoM Code Using RWG Basis Functions and ScaLAPACK-Based In-Core and Out-of-Core Solvers A Parallel MoM Code Using Higher-Order Basis Functions and ScaLAPACK-Based In-Core and Out-of-Core Solvers Turning the Performance of a Parallel Integral Equation Solver Refinement of the Solution Using the Conjugate Gradient Method A Parallel MoM Code Using Higher-Order Basis Functions and Plapack-Based In-Core and Out-of-Core Solvers Applications of the Parallel Frequency Domain Integral Equation Solver Appendices are provided with detailed information on the various computer platforms used for computation; a demo shows you how to compile ScaLAPACK and PLAPACK on the Windows® operating system; and a demo parallel source code is available to solve the 2D electromagnetic scattering problems. Parallel Solution of Integral Equation-Based EM Problems in the Frequency Domain is indispensable reading for computational code designers, computational electromagnetics researchers, graduate students, and anyone working with CEM software.
The present issue of Structure and Bonding is dedicated to applied group 13 chemistry, particularly for the elements boron and aluminum, and to a lesser degree gallium and indium. Although boron is a trace element (0.01 g kg 1) in the earth's crust, it has been concentrated in a few locations by geochemical processes and is relatively easy to mine as borax. Aluminum, on the other hand, is the most abundant metal in the earth's crust (82 g kg 1) and dispersed widely throughout the globe. Thus, boron and aluminum are readily available and their associated products or compounds are usually inexpensive and thereby easy to commercialize. The chapters were chosen to encompass both applied and fundamental aspects of their subiects. The first chapter 'Borates in Industrial Use' provides a complete, and perhaps, quintessential, coverage of compounds containing boron oxygen bonds. In the chapter Schubert explains the close relationship between the basic properties of the boron compounds and their associated uses. The remaining four chapters focus, to some degree, on aluminum. Since a great deal of literature exists in this area, these chapters are more focused on areas of emerging utility, and contain a great deal of fundamental information. Uhl's contribution in Chapter 2 provides basic synthesis and structural information for aluminum and gallium hydrazides. These types of compounds are being explored as potential molecular precursors to metal nitrides such as the important blue green laser material gallium nitride.
Based upon empirical research this book explores the process of China's corporatization reform and investigates whether the reform has altered the process of strategy formulation and implementation of large Chinese SOEs. What processes of ownership restructuring are taking place in the large SOEs and what impact do these changes have?
This book provides a powerful diagnosis of why the global governance of science struggles in the face of emerging powers. Through unpacking critical events in China and India over the past twenty years, it demonstrates that the ‘subversiveness’ assumed in the two countries’ rise in the life sciences reflects many of the regulatory challenges that are shared worldwide. It points to a decolonial imperative for science governance to be responsive and effective in a cosmopolitan world. By highlighting epistemic injustice within contemporary science, the book extends theories of decolonisation.
This book is a reinterpretation of China's international relations since 1949. Employing the notion and theory of international society, it offers a systematic examination of China's unique relationship with the society of states from its alienation in the 1950s and the 1960s to its political socialisation and economic integration in the 1980s and the 1990s. It explores how such a unique relationship has shaped and is likely to shape Chinese foreign policy. This book provides an entirely new perspective for our understanding of forces influencing Chinese foreign policy behaviour.
China is well-known as the largest recipient of foreign direct investment among developing countries. Little is known so far of the fact that China has become (quietly) one of the most significant third world investors in the global economy. This book traces the evolutionary path of China's outward investment activities and examines the political economy of the rapid rise of China's global businesses in the context of the economic reforms since 1978. The analysis of changing policy regimes for China's outward investment is complemented by detailed investigations of the rise and operation of three pioneering Chinese multinationals to illustrate this new thrust of China's engagement with the global economy. China's global reach examined in this study explores issues concerning China's creative responses to globalisation and the processes through which China his becoming a globalised state. The first ever book-length study of China's global investment activities, this book fills a significant gap in the literature on China's economic transformation and the rise of multinational corporations from developing countries.
Numerical solutions of electromagnetic field problems is an area of paramount interest in academia, industry and government. This book provides a compendium of solution techniques dealing with integral equations arising in electromagnetic field problems in time and frequency domains. Written by leading researchers in the field, it documents the authors' unique space/time separation approach using Laguerre polynomials. Numerous examples that illustrate the various methodologies and user-friendly computer codes make this volume highly accessible for engineers, researchers, and scientists.
Asbestos have been used in many different environments, including industrial and home construction projects, vehicles, railroads and shipyards, to name a few. Asbestos have significantly affected many lives, particularly individuals and their families who have experienced substantial direct or indirect occupational exposure to asbestos as well as asbestos-containing products and equipment. Many diseases and conditions are reported to have a direct or indirect causal link to asbestos exposure. This book summarizes the historical background, current knowledge and advancements concerning asbestos and its related diseases in a simple, easy to understand and concise format. The first chapter covers asbestos mineralogy, industrial applications, occupational and environmental exposure as well as methods of fiber analysis. The second chapter focuses on asbestos pathogenesis, including asbestos levels in the environment and various worksites, the biological effects of asbestos fibers and factors determining its toxicity. The third chapter provides an overview of asbestos-related diseases such as asbestosis, pleural diseases, lung cancer and mesothelioma. Each section also includes a discussion of cause and causation, clinical presentation, pathology, diagnosis, treatment, prognosis and surveillance. The fourth chapter outlines the basic concepts of biostatistics and epidemiology, criteria in establishing the causal relationships, the occupational approach of environmental diseases and current standards and regulations. This book serves as an easy to read, quick reference presented in a bulleted format that allows readers to quickly and easily review the information. It is a useful resource for occupational medicine specialists, healthcare providers and environmental scientists who are interested in understanding asbestos and managing asbestos-related diseases.
