This proposed book focuses on the design and development of printed antennas along with modeling aspects for multifaceted applications. It further investigates imperfections in the manufacturing processes and assembly operation during the testing/characterization of printed antennas. There has been enormous growth in printed antenna technology for future-generation wireless communication and healthcare services, covering radio-frequency (RF) and microwave gametes. Efforts are already underway for extending the same technology to sub-THz (Terahertz) waves. THz technology is also knocking at the door of antenna engineers with tremendous potential in miniaturization and promising features for strategic applications. This book is a practical antenna design guide, covering various real-world applications for those who are plunging into this field. It blends proportionately insight theory and practical design issues of antenna engineering in a beautiful manner. It stems from the extensive experiences of the authors in the analysis, design, and development of various miniaturized printed antennas for future-generation wireless communication and biomedical applications. The profound knowledge of both authors on the subject makes this book an authoritative contribution in the field.

This book is designed for both the scientific audience, research and development engineers and the university students. The fundamentals of radio frequency antenna beam forming is explained in this book. The principles of beam focusing and beam steering in near field and far field are visualized with 2D and 3D simulations and compared with measurement results. Besides linear and planar antenna arrays, also conformal arrays, i.e. concave and convex antenna arrays, suitable for certain applications, are investigated and presented. Also related applications of radio frequency beam forming like open loop and closed loop large scale antenna arrays or massive MIMO, which is one of the break-through technologies for 5G and future 6G and involves an extremely large number of antenna elements for the multi-user beam forming, as well as thinned antenna arrays with electrically large distances between the antenna elements are discussed. This book has been written for students in Electrical and Electronics Engineering and Information Technology. It is also written for radio frequency (RF) engineers to give a technology oriented overview of phased array antennas, beam steering and beam forming. This may allow engineers and also project managers, involved in RF design, to develop visions and opportunities with their own applications.

A comprehensive introduction to the mathematical foundations of movement and actuation that apply equally to animals and machines. This textbook offers a computational framework for the sensorimotor stage of development as applied to robotics. Much work in developmental robotics is based on ad hoc examples, without a full computational basis. This book's comprehensive and complete treatment fills the gap, drawing on the principal mechanisms of development in the first year of life to introduce what is essentially an operating system for developing robots. The goal is to apply principles of development to robot systems that not only achieve new levels of performance but also provide evidence for scientific theories of human development. Robotics is a unique discipline in that it affords us the ability to study sophisticated machines and computation simultaneously in a platform where we can precisely control experimental studies of intelligence.

This is a book about computer organization and architecture. It focuses on the function and design of the various components necessary to process information digitally. Computing systems are presented as a series of layers, starting with low-level hardware and progressing to higher-level software, including assemblers and operating systems. These levels constitute a hierarchy of virtual machines. The study of computer organization focuses on this hierarchy and the issues involved with how to partition the levels and how each level is implemented. The study of computer architecture focuses on the interface between hardware and software, and emphasizes the structure and behavior of the system. The majority of information contained in this textbook is devoted to computer hardware, computer organization and architecture, and their relationship to software performance. There is a fundamental relationship between the computer hardware and the many aspects of programming and software components in computer systems. In order to write good software, it is very important to understand the computer system as a whole. Understanding hardware can help you explain the mysterious errors that sometimes creep into your programs, such as the infamous segmentation fault or bus error.

Most of the real-life signals are non-stationary in nature. The examples of such signals include biomedical signals, communication signals, speech, earthquake signals, vibration signals, etc. Time-frequency analysis plays an important role for extracting the meaningful information from these signals. The book presents time-frequency analysis methods together with their various applications. The basic concepts of signals and different ways of representing signals have been provided. The various time-frequency analysis techniques namely, short-time Fourier transform, wavelet transform, quadratic time-frequency transforms, advanced wavelet transforms, and adaptive time-frequency transforms have been explained. The fundamentals related to these methods are included. The various examples have been included in the book to explain the presented concepts effectively. The recently developed time-frequency analysis techniques such as, Fourier-Bessel series expansion-based methods, synchrosqueezed wavelet transform, tunable-Q wavelet transform, iterative eigenvalue decomposition of Hankel matrix, variational mode decomposition, Fourier decomposition method, etc. have been explained in the book. The numerous applications of time-frequency analysis techniques in various research areas have been demonstrated.
