Underwater Acoustic Modeling and Simulation examines the translation of our physical understanding of sound in the sea into mathematical models that can simulate acoustic propagation, noise and reverberation in the ocean. These models are used in a variety of research and operational applications to predict and diagnose the performance of complex sonar systems operating in the undersea environment. Previous editions of the book have provided invaluable guidance to sonar technologists, acoustical oceanographers and applied mathematicians in the selection and application of underwater acoustic models. Now that simulation is fast becoming an accurate, efficient and economical alternative to field-testing and at-sea training, this new edition will also provide useful guidance to systems engineers and operations analysts interested in simulating sonar performance. Guidelines for selecting and using available propagation, noise and reverberation models are highlighted. Specific examples of each type of model are discussed to illustrate model formulations, assumptions and algorithm efficiency. Instructive case studies demonstrate applications in sonar simulation.
This unique volume is not just an in-depth analysis of Professor Swaminathan's brilliant contributions to basic cytogenetics, radiation biology, mutagenesis and genomic affinities of cultivated potato and its wild derivatives, but also the application of the new knowledge gained to improve the productivity of agricultural crops, as also to enhance their resistance to a variety of biotic and abiotic stresses. No other earlier biographies of Professor Swaminathan bring out these salient dimensions of his scientific achievements made at the Wageningen University, The Netherlands, Cambridge University, UK, and Wisconsin University, USA as well as Indian Agricultural Research Institute (IARI), New Delhi. This biography is also unique for its revelation that Professor Swaminathan's contributions par excellence have been in contemporary areas of crop improvement for productivity and resistance to pests and diseases.This volume is also unique in bringing out that Professor Swaminathan, Father of India's Green Revolution, wanted to use this chemically intensified system only to gain 'breathing space' and went on to propose a 'systems approach' — based evergreen revolution in order to 'achieve productivity in perpetuity' through various pathways of ecoagriculture, and also integrated it with avenues for on-farm and non-farm livelihoods. Towards this goal, he made innovative uses of ecotechnologies in a 'biovillage' paradigm and modern information and communication technology (ICT) in Village Knowledge Centres (VKCs) to provide skill and knowledge empowerment respectively of the resource-poor rural women and men towards sustainable management of the natural resources for creating income-generating on-farm and non-farm livelihoods. This volume also brings out how Professor Swaminathan elegantly combined intellect and labour (hard work), and professional zeal with compassion for the poor. He is always open to new ideas, and new technologies without of course, compromising the values of traditional knowledge and ecological prudence of the rural and tribal people. This volume nicely captures how Professor Swaminathan with a deep and comprehensive understanding of the threats to the ecological foundations of agriculture and sustainable rural development, environmental degradation, social inequities and the climate change risks, has also harnessed science and technology to convert challenges into opportunities. This volume is written in a manner to serve also as a text book, going beyond the scope of just a biography. That should benefit generations of students on one hand, and sustain an interest in the book for many years on the other.

Quantum Mechanics will enthuse graduate students and researchers and equip them with effective methodologies for challenging applications in atomic, molecular, and optical sciences and in condensed matter and nuclear physics also. This book attempts to make fundamental principles intuitively appealing. It will assist readers in learning difficult methods. Exposition of fundamental principles includes a discussion on position-momentum and energy-time uncertainty, angular momentum algebra, parity, bound and unbound eigenstates of an atom, approximation methods, time-reversal symmetry in collisions, and on a measurable time delay in scattering. It also provides an early introduction to Feynman path integrals and to geometric phase. A novel Lambert-W method to solve quantum mechanical problems is also introduced. It seeks to enable readers gain confidence in applying methods of non-relativistic and relativistic quantum theory rigorously to problems on atomic structure and dynamics, spectroscopy and quantum collisions, and problems on introductory quantum information processing and computing.

In the last seven years, following the publication of the first edition of this book, the field of powder metallurgy has produced a number of advanced and useful technologies. In order to make the book relevant and useful to its target readership two new chapters have been added in its second edition. The chapter on Recent Advances in Micro- and Nano-fabrication through Powder Metallurgy deals with the fabrication of micro-grained bulk structure and for manufacturing of nano-sized components using metal and ceramic powders by recent techniques. The chapter on Additive Manufacturing (AM) discusses one of the most exciting innovations in the field of powder metallurgy in recent times. In the last three decades, a number of AM processes have been developed which use either laser sources or electron beams to fuse the metallic or ceramic or composite powders. The book covers most of the recent developments in powder metallurgy such as atomization, mechanical alloying, self-propagating high-temperature synthesis, metal injection moulding, and hot isostatic pressing. Model questions have been given at the end of each chapter. An appendix of relevant terms in powder metallurgy has also been included for ready reference. The book is primarily written for undergraduate and postgraduate students of Metallurgy, Material Science, Mechanical, and Production Engineering, as well as for practicing engineers in the field of powder metallurgy. TARGET AUDIENCE • UG and PG (Metallurgy, Material Science, Mechanical, and Production Engineering) • Practising Engineers in the field of Powder Metallurgy.
This book is a compendium of essays on various science related topics which are at the cutting edge of modern science and technology. Sixteen different science topics are discussed in the book, which include origin and evolution of the universe, the microscopic world of the atom, unification of the forces of nature, our planet earth and its neighbors, modern developments in synthetic biology, global warming, artificial intelligence and the explosive growth of information technology. The book exposes its readers having a modest science background to some of the most exciting developments in modern science. Keeping this in view the discussion is kept at a simple level without excessive use of mathematics and abstract concepts. While aiming at simplicity and coherence every effort is made not to compromise on accuracy. We are living in an era where scientists specializing in a particular area are hardly aware of the happenings in related disciplines. This book aims at bridging this gap. Finally there are sizable sections of science educated lay public who are curious to understand the how and the why of modern scientific developments at a very basic level. It is hoped that this book will be helpful in satisfying their curiosity.
Written in easily accessible language, the book provides a modern perspective of classical mechanics. Mathematical rigour is intertwined with lucid narration that will generate confidence in students to assimilate and apply fundamental principles of physics. The commonalities and differences of Newton's, Lagrange's and Hamilton's equations are explained in detail. Free, damped, driven oscillators and resonances are analysed systematically. The text extensively covers concepts of fluid mechanics, special theory of relativity, general theory of relativity and Lorentz transformations. The theories of gravitational field, fractals and chaos, Maxwell's laws of electrodynamics, and Einstein's theory of relativity are expanded from the first principle. The text is supported by practice problem sets to help students check their understanding of the concepts.
