The scope of maintenance functions in the Indian Air Force (IAF) is vast. The need for a very specialised professional conduct in each one of these is obvious from the width of deliberations in this book. Further, the reader can appreciate the virtues of an integrated approach to maintenance. The text is, therefore, as relevant to the aircrew as it is to the engineers, technicians and logisticians. The paradigm of maintenance has attained a unique character over the years in the IAF despite legacies from its British genesis. Maintenance philosophies have been adaptively developed to support ever growing air power dimensions and exclusive indigenous requirements. A maintenance engineer in the IAF gets involved with every engineering aspect of planning, design/development, acquisition and projects besides maintenance and logistics support to operations. Unlike most other air forces, the communications and Information Technology (IT) disciplines are also taken on by the maintenance man in the IAF. All activities within the maintenance arena have been dealt with ingeniously in this book. This book reviews diverse fields of engineering activities. Beginning with the need for an organisational fusion, an array of specialised functions has been presented to finally suggest an integrated maintenance approach. Quality discipline and goal alignment are prime factors - emphasis on these runs through all the discussions. Learning from nearly four decades of experience in the Air Force, a few mindsets have been highlighted, with suggestions for a paradigm shift. It is always fascinating to relive memories of leaders who shaped our destiny. These examples have the potential to send a surge of renewed motivation through every air warrior. The chapter on the work force is a tribute to the commitment of airmen and civilians. This book is a first in many ways. The need for transformational thinking with a systems' view has been advocated for all actions related to a subject as sedate as maintenance. Contributions from different variables viz. infrastructure, material, technology, processes and people, above all, have to be in sync to produce the desired air power outcome. The objective of this book is not to prescribe a solution but to provoke thinking about new paradigms for improvement.

This new and expanded monograph improves upon Mohan's earlier book, Residue Number Systems (Springer, 2002) with a state of the art treatment of the subject. Replete with detailed illustrations and helpful examples, this book covers a host of cutting edge topics such as the core function, the quotient function, new Chinese Remainder theorems, and large integer operations. It also features many significant applications to practical communication systems and cryptography such as FIR filters and elliptic curve cryptography. Starting with a comprehensive introduction to the basics and leading up to current research trends that are not yet widely distributed in other publications, this book will be of interest to both researchers and students alike.

A multi-faceted creative personality, Rabindranath Tagore is one of the greatest stalwarts of both English and Bengali literatures. He created a Renaissance in India, where people were awakened by the great corpus of creative work produced during the country's struggle for independence from the British. Tagore was undoubtedly a champion of this literary protest. He produced masterpieces in Bengali literature and later translated them into English. Gitanjali, his masterpiece collection of poems with a foreword by William Butler Yeats, is renowned for its rhythmic, optimistic, and lyrical nature. It won Tagore the Nobel Prize for Literature, the first awarded to an Asian writer, and a knighthood. In this landmark study, noted Indian scholar P. V. Laxmiprasad offers the most comprehensive critical study of Tagore's work to date.

This book discusses human-machine interactions, specifically focusing on making them as natural as human-human interaction. It is based on the premise that to get the right connect between human and machines, it is essential to understand not only the behavior of the person interacting with the machine, but also the limitations of the technology. Firstly, the authors review the evolution of language as a spontaneous, natural phenomenon in the overall scheme of the evolutionary development of living beings. They then go on to examine the possible approaches to understanding and representing the meaning and the common aspects of human-human and human-machine interactions, and introduce the keyconcept-keyword (also called minimal parsing) approach as a convenient and realistic way to implement usable human-machine interface (HMI) systems. For researchers looking for practical approaches, way beyond the realms of theory, this book is a must read.

Non-Destructive Evaluation (NDE) is now playing an increasing role in the modern global economy, in security-sensitive industries, for instance. The complexity of the inspection task and either large or limited lot runs now require more operator-assisted or fully automated signal processing. This book deals with both fields of expertise: NDE and signal processing. On the signal processing side, in the particular context of NDE applications, the following topics are discussed: sensor fusion, signal knowledge representation, artificial intelligence, fuzzy logic, computer vision, integration of numeric and non-numeric informations, parallel decomposition, noise processing and calibration of sensor devices as well as reliability of detection. Some hardware considerations are introduced as well, to discuss platforms on which processing is done. On the NDE side, applications include advances in holographic inteferometry, microwave resonance or shearography and also on more traditional NDE techniques such as ultrasonics, infrared techniques, X-ray, computed tomography and Eddy currents. Inverse problems are also discussed. This book is suitable for those who already have some experience in one or both fields (signal processing and/or NDE).

Great strides have been made in the development of analog filters over thepast few decades. The first book to treat these recent advancesin depth, "VLSI Analog Filters" provides a comprehensive guide for researchers and upper-level graduate students, whichfully preparesreaders for professional work. In particular, the work covers active R filters, OTA-C filters, and switched-capacitor filters, including topics such as differential output opamps, sensitivity analysis for passive components, multiple-feedback techniques, double-sampling, and N-path filters. Throughout the book, exercises are included to reinforce understanding of concepts, and simulations are used to enhance connections to practical applications.

This advanced textbook is suitable for engineeringgraduate students studying analog filter design, offering a full course that can feed seamlessly toemployment industry. At the same time, it serves asan extremely valuable referencefor researchers and engineerslooking to gain a deeper understanding of the field."

Current-mode design is of great interest to high-tech analog designers today, who are principally concerned with designing whole systems on a chip. This work focuses on the theory and methods of many important current-mode circuit design techniques making it a comprehensive technical overview that fills a gap in the current literature.
The purpose of the book is to compile all available information in the area of OTA-C filters, current conveyor and CFOA based filters, switched-current filters, and log-domain filters into one complete reference volume. Practical applications of current-mode design techniques for realizing practical VLSI systems such as disk drive read channel ICs and video filters are covered in detail. The background required for this book is an exposure to a first course in active RC filters, digital signal processing and optionally, some knowledge of switched capacitor filters.
