From the introduction: "The natural vegetation of the district Palamau is now facing a severe threat due to increasing urbanization. The 'Flora' may help in listing of several endangered, threatened and rare species. Moreover, it will create an awareness amongst the people as a whole to protect such species from extinction and to take necessary steps for conservation of our ecosystem and environment. Thus 'Flora' is an essential inventory in this respect and hence a necessity to wide range of users. "The district is floristically rich and was formerly a district of Chotanagpur division. The flora of the district is essentially tropophilous though in some parts there is a tendency to xerophily. One of the conspicuous topographical features of the district is the presence of Natarhat Hill (1126 m) which is situated on the border of Gumla and Palamau district and this hilly terrain subtends both temperate and tropical vegetation. From the botanical point of view this region is of high interest due to its affinity with the rich flora of Madhya Pradesh which lies in the border of Palamau. It usually gives rise to reddish 738 pp. …

Hardback. Condición: New. 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 SolversA Parallel MoM Code Using Higher-Order Basis Functions and ScaLAPACK-Based In-Core and Out-of-Core SolversTurning the Performance of a Parallel Integral Equation SolverRefinement of the Solution Using the Conjugate Gradient MethodA Parallel MoM Code Using Higher-Order Basis Functions and Plapack-Based In-Core and Out-of-Core SolversApplications 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.…

Hardback. Condición: New. Important new insights into how various components and systems evolved Premised on the idea that one cannot know a science without knowing its history, History of Wireless offers a lively new treatment that introduces previously unacknowledged pioneers and developments, setting a new standard for understanding the evolution of this important technology. Starting with the background-magnetism, electricity, light, and Maxwell's Electromagnetic Theory-this book offers new insights into the initial theory and experimental exploration of wireless. In addition to the well-known contributions of Maxwell, Hertz, and Marconi, it examines work done by Heaviside, Tesla, and passionate amateurs such as the Kentucky melon farmer Nathan Stubblefield and the unsung hero Antonio Meucci. Looking at the story from mathematical, physics, technical, and other perspectives, the clearly written text describes the development of wireless within a vivid scientific milieu. History of Wireless also goes into other key areas, including: The work of J. C. Bose and J. A. FlemingGerman, Japanese, and Soviet contributions to physics and applications of electromagnetic oscillations and wavesWireless telegraphic and telephonic development and attempts to achieve transatlantic wireless communicationsWireless telegraphy in South Africa in the early twentieth centuryAntenna development in Japan: past and presentSoviet quasi-optics at near-mm and sub-mm wavelengthsThe evolution of electromagnetic waveguidesThe history of phased array antennas Augmenting the typical, Marconi-centered approach, History of Wireless fills in the conventionally accepted story with attention to more specific, less-known discoveries and individuals, and challenges traditional assumptions about the origins and growth of wireless. This allows for a more comprehensive understanding of how various components and systems evolved. Written in a clear tone with a broad scientific audience in mind, this exciting and thorough treatment is sure to become a classic in the field. …
