Today, air-to-surface vessel (ASV) radars, or more generally airborne maritime surveillance radars, are installed on maritime reconnaissance aircraft for long-range detection, tracking and classification of surface ships (ASuW--anti-surface warfare) and for hunting submarines (ASW--anti-submarine warfare). Such radars were first developed in the UK during WWII as part of the response to the threat to shipping from German U boats. This book describes the ASV radars developed in the UK and used by RAF Coastal Command during WWII for long-range maritime surveillance.

This book introduces sonar system and acoustic channel model, average energy channel, coherent multipath channel, the theoretical basis for the stochastic time-varying space-variant channel, slowly time-varying coherent multipath channel, and reverberation channel. Based on the basic theory of underwater acoustic channels and the various characteristics of the marine acoustic environment factor, this textbook aims to help students understand the impact of the marine acoustic channel on the sonar system. It helps students to grasp underwater acoustic signal processing principles and obtain the ability to solve practical problems in underwater acoustic channel engineering. Finally, it aims at laying a foundation for the further sonar system design. This textbook is recommended for graduate or undergraduate students in the field of sonar signal processing, underwater acoustic engineering, as well as some related subjects of marine technology.

Several evolutionary algorithms (EAs) have emerged in recent decades that mimic the behaviour and evolution of biological entities. EAs are widely used to solve single and multi-objective optimization engineering problems. EAs have also been applied to a variety of microwave components, antenna design, radar design, and wireless communications problems. These techniques, among others, include genetic algorithms (GAs), evolution strategies (ES), particle swarm optimization (PSO), differential evolution (DE), and ant colony optimization (ACO). In addition, new innovative algorithms that are not only biology-based but also physics-based or music-based are also emerging, as are hybrid combinations of EAs. The use of evolutionary algorithms is having an increasing impact on antenna design and wireless communications problems. EAs combined with numerical methods in electromagnetics have obtained significant and successful results. This book aims to present some of the emerging EAs and their variants. Chapter 1 introduces the optimization methods in general and the evolutionary algorithms. Chapter 2 presents briefly some of the most popular evolutionary algorithms, such as particle swarm optimization (PSO), differential evolution (DE), and ant colony optimization (ACO) as well as some emerging ones. Chapter 3 focuses on antenna array synthesis, which constitutes a wide range of antenna design problems. Chapter 4 gives an overview of patch antenna design using evolutionary algorithms. Chapter 5 presents design cases from different microwave structure cases. Chapter 6 discusses on various representative design problems in wireless communications. Chapter 7 deals with design cases for 5G and beyond.

Internet of Things (IoT) enabled technology is evolving healthcare from conventional hub-based systems to more personalized eHealth systems, enabling faster and safer preventive care, lower overall cost, improved patient-centric practice and enhanced sustainability. Efficient IoT-enabled eHealth systems can be realized by providing highly customized access to rich medical information and efficient clinical decisions to each individual with unobtrusive monitoring. Wireless medical sensor networks (WMSNs) are at the heart of this concept, and their development is a key issue if such a concept is to achieve its potential. This book addresses the major challenges in realizing WMSNs in forthcoming IoT-based eHealth systems. Challenges vary from cost and energy efficiency to security and service quality, and to tackle such challenges WMSNs must meet certain expectations and requirements such as size constraints, manufacturing costs and resistance to environmental factors existing at deployment locations. Reflecting this the book focuses on both design and implementation aspects. Topics covered include the impact of medical sensor networks in smart-cities; an evaluation of mobile patient monitoring technologies; overview of wireless sensor devices in medical applications; cyber security issues in WMSNs and eHealth; smart hospital rooms and automated systems; medical sensor capabilities in smart cloud networks; swarm intelligence based medical diagnosis systems; and smart systems and device for the blind.

The International Communications Satellite Systems Conference (ICSSC) is one of the most influential technical conferences in the field. The 36th edition was held in October 2018 in Niagara Falls, Canada. These proceedings present a broad spectrum of space communications topics from the conference, from the evolution of GEO from traditional area coverage to Ultra High Throughput Satellites (UHTS), the growing number of mega constellations expected to enter service in the next decade, navigation applications such as vehicle autonomy, wideband data backhaul from scientific and remote sensing payloads in LEO, and the extension of the 5G network to near earth, lunar and deep space environments in support of human exploration.

By 2007, electricity demand in Namibia, Southern Africa, outstripped the supply capacity in the region. Namibia relies on other sources to provide 53 percent of its local electricity needs. This disparity necessitated either the introduction of new generation capacity or load management to supply the shortfall in electricity demand, with a subsequent rise in electricity costs.

In Electricity Use in Namibia, author Dr. Godwin Norense Osarumwense Asemota explores load management methodologies vital to the effective, efficient, and successful operation of any power utility-in order to reduce electricity demand peaks, lower utility production cost, reduce consumer cost, match consumer loads with supply constraints, and improve availability.

Asemota provides the background of the study, discusses the historical perspective of Namibian Utility, presents a literature review, details the research methodology, shares the results of the questionnaire through figures and tables, provides thorough analyses, and offers a conclusion and recommendations. Electricity Use in Namibia communicates the steps necessary to strengthen Namibia's electricity backbone in order to facilitate a stable future for the country.
