Описание: For over five hundred years, Muslim dynasties ruled parts of northern and central India. Scholars have long drawn upon works written in Persian and Arabic about this epoch, yet they have neglected the many histories that India`s learned elite wrote about Indo-Muslim rule in Sanskrit. Audrey Truschke offers a groundbreaking analysis of these texts.
Описание: This book fills in details that are often left out of modern books on the theory of antennas. The starting point is a discussion of some general principles that apply to all electronic systems and to antennas in particular. Just as time domain functions can be expanded in terms of sine waves using Fourier transforms, spatial domain functions can be expanded in terms of plane waves also using Fourier transforms, and K-space gain is the spatial Fourier transform of the aperture weighting function. Other topics discussed include the Discrete Fourier Transform (DFT) formulation of antenna gain and what is missing in this formulation, the effect of sky temperature on the often specified G/T ratio of antennas, sidelobe control using conventional and novel techniques, and ESA digital beamforming versus adaptive processing to limit interference. Presents content the author derived when first asked to evaluate the performance of an electronically scanned array under design with manufacturing imperfections and design limitations;Enables readers to understand the firm theoretical foundation of antenna gain even when they must start from well-known formulations rather than first principles;Explains in a straightforward manner the relationship between antenna gain and aperture area;Discusses the relationship between sidelobe control algorithms and aperture shape, how to take advantage of it, and what the penalties are;Shows the equivalence of Minimum-Variance, Distortionless Response (MVDR) and Space-Time Adaptive Processing (STAP) and how these algorithms can be used with ESA subarrays to mitigate interference.
Описание: "[Contains] more lengthy mathematical derivations than most {comparable books] … for arrays, provides for a unique, stand-alone mathematical description that can be adopted by anyone trying to communicate the theoretical foundation for their array design…has insights from a practitioner that are unique. The MATLAB® scripts alone are worth the price." —Daniel C. Ross, Ph. D, Northrop Grumman Corporation Electronically Scanned Arrays: MATLAB® Modeling and Simulation is considered the first book to provide comprehensive modeling/simulation programs used to design and analyze Electronically Scanned Arrays (ESA), a key technology internationally in the scientific and engineering communities. Several books have been written about ESAs, but most cover only fundamental theory. Few, if any, provide the insightful, easy-to-use simulation tools found in this book. Obviously, MATLAB® is one of the greatest tools available for exploring and understanding science and engineering concepts, and we use MATLAB functions to easily and instantly calculate ESA patterns. However, to achieve a truly insightful and in-depth analysis of subarray architectures, conformal arrays, etc., it is imperative that users first develop a firm grasp of ESA fundamentals. Covers largely unexplored topics, such as reliability aspects and the application of ESAs in space This volume helps readers build that elemental understanding of how ESAs work. It also provides code to run as an aid, so that readers don’t have to start from scratch. The book expands on ESA principles and provides a modeling framework, using MATLAB to model applications of ESAs (i.e. pattern optimization, space-based applications, and reliability analysis). Presented code serves as an excellent vehicle to help readers master the analysis and simulation of ESAs. Exploring how difficult problems can be simplified with short, elegant solutions, this is an invaluable resource for students and others new to ESAs, as well as experienced practicing engineers who model ESAs at the systems level.

Описание: In The Four Ages of American Foreign Policy, the eminent authority on American foreign policy Michael Mandelbaum offers a new framework for understanding the history of the foreign policy of the United States. He divides that history into four distinct periods, each of them defined by the consistent increase in the power the country has had at its disposal in its relations with other countries.

Описание:
Electronic Scanned Array Design covers the fundamental principles of ESA antennas including basic design approaches and inherent design limitations. These insights enable better appreciation of existing and planned ESA systems including their application to earth observation. The material describes general design principles of aperture antennas applied to the specific case of ESA design.
System applications are discussed to set the framework for requirements allocation and flowdown. Specific examples are cited throughout to relate theory to practice. The book begins by introducing the concept of electronic scanned arrays, giving a brief history of the technology and outlining its scope and applications. Further chapters cover antenna principles; synthetic arrays; antenna figures of merit; mutual coupling effects; errors and tolerances; grating lobes; thinned arrays; beam width and sidelobes; beam shaping and spoiling; reflector applications; design practice; radiating elements; T/R modules; assembly, packaging, power and thermal management; technology base and cost; and ESAs in space. The final chapter offers a comparison between an ESA and a reflector, exploring their benefits, detriments and design trades.
The book will be invaluable for radar and antenna engineers and researchers, and advanced students studying ESA design.
Описание: This book examines the theoretical underpinning of the concept of personalised education and explores the question: What is personalised education in the contemporary higher education sector and how is it implemented?

Описание:
Although we live in an era in which we are surrounded by an ever-deepening fog of data, few of us truly understand how the data are created, where data are stored, or how to retrieve or destroy data--if that is indeed possible. This book is for all of you, whatever your need or interest.
Electronically Stored Information: The Complete Guide to Management, Understanding, Acquisition, Storage, Search, and Retrieval, Second Edition explains the reasons you need to know about electronic data. It also gets into great detail about the how, what, when, and where of what is known in legal circles as electronically stored information (ESI). With easy-to-understand explanations and guidelines, this book provides the practical understanding you need to effectively manage the complex world of ESI. Whether you are an attorney, judge, paralegal, business manager or owner, or just one of the ever-growing population of computer users, you will benefit from the information presented in this book.
