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.

Part of IOP Series in Sensors and Sensor Systems. Cognitive sensors have become essential parts of a number of Internet of Things (IoT) devices and modern gadgets. In fact, the sensors which behave and act smartly in all modern applications are cognitive sensors. Sensors that have the ability to understand and interpret the data they sense, with the help of signal processing and Machine Learning techniques, are known as cognitive sensors. Cognitive sensors are heavily used in healthcare applications, smart city smart transport, smart manufacturing, smart automobiles, and a number of other such applications in which automation is achieved using sensor-based data and the analysis of sensor-based data using Artificial Intelligence (AI)-based approaches.

This book is about developing apps for Android compatible mobile devices using the MIT App Inventor online development environment. MIT App Inventor projects can be in either standalone mode or use an external processor. In standalone mode, the developed application runs only on the mobile device. In external processor-based applications, the mobile device communicates with an external microcontroller-based processor, such as Raspberry Pi, Arduino, ESP8266, ESP32, etc. In this book, many tested and fully working projects are given both in standalone mode and using an external processor. Full design steps, block programs, circuit diagrams, QR codes and full program listings are given for all projects. All projects presented in this book have been developed using the MIT App Inventor visual programming language. MIT App Inventor is GUI based and is similar to Scratch and StarLogo, where developers drag and drop and join visual blocks to create an application.

This book explores new methods, architectures, tools, and algorithms for Artificial Intelligence Hardware Accelerators. The authors have structured the material to simplify readers’ journey toward understanding the aspects of designing hardware accelerators, complex AI algorithms, and their computational requirements, along with the multifaceted applications. Coverage focuses broadly on the hardware aspects of training, inference, mobile devices, and autonomous vehicles (AVs) based AI accelerators. Smart technologies and an intelligent society are the demand of this era. Artificial Intelligence (AI) and Deep Learning (DL) algorithms are playing a vital role to cater these demands to meet the expectations of the smart world and intelligent systems. Increased computing power, sensor data, and improved AI algorithms are driving the trend toward Machine Learning (ML) in cloud-based and edge-based intelligence. Both are applicable through intelligent devices, wearable electronics, smartphones, automobiles, robots, drones, etc. However, efficient hardware can solely accomplish the required performance of implementing these algorithms. Therefore, AI accelerators are the state-of-the-art research area for circuits and systems designers and academicians. AI accelerators are needed to cater to the insatiable demands of compute-intensive AI applications.
