Adaptive Hybrid Active Power Filters (Power Systems)
by Lei Wang Man-Chung Wong Chi-Seng LamThis book introduces advanced thyristor-based shunt hybrid active power filters (HAPFs) for power quality improvement in power grids, which are characterized by a low dc-link operating voltage and a wide compensation range. This means they can overcome the high dc-link voltage requirement of conventional active power filters and the narrow compensation range problem of LC-coupling hybrid active power filters. Consisting of 10 chapters, the book discusses the principle, design, control and hardware implementation of thyristor-based hybrid active power filters. It covers 1) V-I characteristics, cost analysis, power loss and reliability studies of different power filters; 2) mitigation of the harmonic injection technique for thyristor-controlled parts; 3) nonlinear pulse width modulation (PWM) control; 4) parameter design methods; 5) minimum inverter capacity design; 6) adaptive dc-link voltage control; 7) unbalanced control strategy; 8) selective compensation techniques; and 9) the hardware prototype design of thyristor-based HAPFs, verified by simulation and experimental results. It enables readers to gain an understanding of the basic power electronics techniques applied in power systems as well as the advanced techniques for controlling, implementing and designing advanced thyristor-based HAPFs.
Adaptive Hybrid Control of Quadrotor Drones (Studies in Systems, Decision and Control #461)
by Nihal Dalwadi Dipankar Deb Stepan OzanaThis book discusses the dynamics of a tail-sitter quadrotor and biplane quadrotor-type hybrid unmanned aerial vehicles (UAVs) and, based on it, various nonlinear controllers design like backstepping control (BSC), ITSMC (Integral Terminal Sliding Mode Control), and hybrid controller (BSC + ITSMC). It discusses single and multiple observer-based control strategies to handle external disturbances like wind gusts and estimate states. It covers the dynamics of slung load with a biplane quadrotor and a control architecture to handle the effect of partial rotor failure with wind gusts acting on it. An anti-swing control to prevent damage to the slung load and a deflecting surface-based total rotor failure compensation strategy to prevent damage to the biplane quadrotor are also discussed in this book. The monograph will be helpful for undergraduate and post-graduate students as well as researchers in their advanced studies.
Adaptive Identification of Acoustic Multichannel Systems Using Sparse Representations (T-Labs Series in Telecommunication Services)
by Karim HelwaniThis book treats the topic of extending the adaptive filtering theory in the context of massive multichannel systems by taking into account a priori knowledge of the underlying system or signal. The starting point is exploiting the sparseness in acoustic multichannel system in order to solve the non-uniqueness problem with an efficient algorithm for adaptive filtering that does not require any modification of the loudspeaker signals. The book discusses in detail the derivation of general sparse representations of acoustic MIMO systems in signal or system dependent transform domains. Efficient adaptive filtering algorithms in the transform domains are presented and the relation between the signal- and the system-based sparse representations is emphasized. Furthermore, the book presents a novel approach to spatially preprocess the loudspeaker signals in a full-duplex communication system. The idea of the preprocessing is to prevent the echoes from being captured by the microphone array in order to support the AEC system. The preprocessing stage is given as an exemplarily application of a novel unified framework for the synthesis of sound figures. Finally, a multichannel system for the acoustic echo suppression is presented that can be used as a postprocessing stage for removing residual echoes. As first of its kind, it extracts the near-end signal from the microphone signal with a distortionless constraint and without requiring a double-talk detector.

The Adaptive Military: Armed Forces in a Turbulent World
by Peter Jordan Caroline LloydWhen the cold war ended, many hoped it signified enhanced prospects for a more stable world. However, despite favorable political developments, the post-cold war period has been marked by turbulence, uncertainty, and challenge. The actions of rogue states such as Iraq and North Korea have made nuclear proliferation more unpredictable. Violence in Somalia and Bosnia has cast doubt on the viability of international peacekeeping arrangements. Hopes for expanding democratization have been dimmed by assertions that the values of liberal democracy and human rights are incompatible with non-Western cultures. The Adaptive Military describes how military security policies and practices have adapted to these new times and explains why such changes are necessary.The central argument is that current conflicts have been shaped by long-term trends, which increased the number and complexity of threats that the developed world is supposed to meet, and correspondingly decreased the stock of social and political options available to meet them.Although the authors differ in their assessments about the current prospects for peace and ways to maintain security, the issues they address are as critical as they were at the end of the Cold War. Mobilizing resources and political support for remote and difficult enterprises will always remain contentious, but if we recognize the hazard of letting violence run unopposed throughout the world, then we bear some responsibility to consider how it might be checked. This volume is an exercise of that responsibility. It will be of great interest to experts in military studies and international relations.

Adaptive On- and Off-Earth Environments (Springer Series in Adaptive Environments)
by Henriette Bier Angelo Cervone Advenit MakayaThis volume investigates the challenges and opportunities for designing, manufacturing and operating off-Earth infrastructures in order to establish adaptive human habitats. The adaptive aspects are considered with respect to the development of adequate infrastructures designed to support human activities. Given the limitations in bringing materials from Earth, utilisation of in-situ resources is crucial for establishing and maintaining these infrastructures.Adaptive on-and off-Earth Environments focuses, among other aspects, on the design, production, and operation processes required to build and maintain such off-Earth infrastructures, while heavily relying on In-Situ Resource Utilisation (ISRU). Such design, production, and operation processes integrate cyber-physical approaches developed and tested on Earth. The challenge is to adapt on-Earth approaches to off-Earth applications aiming at technology advancement and ultimately transfer from on- to off-Earth research. Thischallenge is addressed with contributions from various disciplines ranging from power generation to architecture, construction, and materials engineering involving ISRU for manufacturing processes. All chapters, related to these disciplines, are structured with an emphasis on computing and adaptivity of on-Earth technology to off-Earth applications and vice versa to serve society at large.

Adaptive Participatory Environmental Governance in Japan: Local Experiences, Global Lessons
by Taisuke Miyauchi Mayumi FukunagaThis book contributes to the theoretical and practitioner literature in environmental governance and sustainability of natural resources by linking case studies of the roles of narratives to the three key practices in local environmental governance: socio-political legitimacy in participation; collaboratively creating stakeholder-ness, and cultivating social and ecological capabilities. It provides numerous theoretical insights on legitimacy, adaptability, narratives, process-oriented collaborative planning, and among others, using in-depth case studies from historical and contemporary environmental issues including conservation, wildlife management, nuclear and tsunami disasters, and thus community risk, recovery, and resiliency. The authors are all practitioner-oriented scientists and scholars who are involved as local stakeholders in these practices. The chapters highlight their action and participatory-action research that adds deeper insights and analyses to successes, failures, and struggles in how narratives contribute to these three dimensions of effective environmental governance. It also shows how stakeholders’ kinds of expertise, in a historical context, help to bridge expert and citizen legitimacy, as well as spatial and jurisdictional governance structures across scales of socio-political governanceOf particular interest, both within Japan and beyond, the book shares with readers how to design and manage practical governance methods with narratives. The detailed design methods include co-imagination of historical and current SESs, designing processes for collaborative productions of knowledge and perceptions, legitimacy and stakeholder-ness, contextualization of contested experiences among actors, and the creation of evaluation standards of what is effective and effective local environmental governance.The case studies and their findings reflect particular local contexts in Japan, but our experiences of multiple natural disasters, high economic growth and development, pollutions, the nuclear power plant accident, and rapidly aging society provide shared contexts of realities and provisional insights to other societies, especially to Asian societies.
Adaptive PHY-MAC Design for Broadband Wireless Systems (River Publishers Series In Communications Ser.)
by Ramjee Prasad Suvra Sekhar Das Muhammad Imadur RahmanThe next generation mobile communication networks (4G) have the challenging target of The next generation mobile communication networks (4G) have the challenging target of providing a peak data rate of 1 Gigabit per second local area and 100 Megabit per second wide area. The ability to offer such high data rates in 100MHz bandwidth requires overall a very high spectral efficiency, and hence the need for multi-antenna techniques (MIMO) with spatial multiplexing, fast dynamic link adaptation and packet scheduling, wideband access techniques, and most likely non-contention based spectrum sharing among multiple operators. Many of these required technology components and techniques are well researched and established. Adaptive PHY-MAC Design for Broadband Wireless Systems explains how one can integrate and optimise their use in providing the target cell data rates with high availability. The authors address the ability to cope with interference and enhanced physical layer processing, and simultaneously, the multifaceted system level design. Focus is also on the selection of technology components and techniques, which leads to the highest spectral efficiency and peak data rate availability with reasonable Quality of Service (QoS) support, such as improved outage scenario, reduced delay, guaranteed bit rate, etc.In short, this book will answer questions such as, how individual techniques relate to each other, how can we benefit the gains by suitable combinations of different technologies and how to choose different technological solutions in different scenarios, etc.The next generation mobile communication networks (4G) have the challenging target of The next generation mobile communication networks (4G) have the challenging target of providing a peak data rate of 1 Gigabit per second local area and 100 Megabit per second wide area.

Adaptive RF Front-Ends for Hand-held Applications (Analog Circuits and Signal Processing)
by Reza Mahmoudi Arthur H.M. van Roermund Andre Van BezooijenThe RF front-end - antenna combination is a vital part of a mobile phone because its performance is very relevant to the link quality between hand-set and cellular network base-stations. The RF front-end performance suffers from changes in operating environment, like hand-effects, that are often unpredictable. Adaptive RF Front-Ends for Hand-Held Applications presents an analysis on the impact of fluctuating environmental parameters. In order to overcome undesired behavior two different adaptive control methods are treated that make RF frond-ends more resilient: adaptive impedance control, and adaptive power control. Several adaptive impedance control techniques are discussed, using a priori knowledge on matching network properties, in order to simplify robust 2-dimensional control. A generic protection concept is presented, based on adaptive power control, which improves the ruggedness of a power amplifier or preserves its linearity under extremes. It comprises over-voltage, over-temperature, and under-voltage protection.
Adaptive Robust Control for Planar Snake Robots (Studies in Systems, Decision and Control #363)
by Joyjit Mukherjee Indra Narayan Kar Sudipto MukherjeeThis book shows how a conventional multi-layered approach can be used to control a snake robot on a desired path while moving on a flat surface. To achieve robustness to unknown variations in surface conditions, it explores various adaptive robust control methods.The authors propose a sliding-mode control approach designed to achieve robust maneuvering for bounded uncertainty with a known upper bound. The control is modified by addition of an adaptation law to alleviate the overestimation problem of the switching gain as well as to circumvent the requirement for knowledge regarding the bounds of uncertainty. The book works toward non-conservativeness, achieving efficient tracking in the presence of slowly varying uncertainties with a specially designed framework for time-delayed control. It shows readers how to extract superior performance from their snake robots with an approach that allows robustness toward bounded time-delayed estimation errors. The book also demonstrates how the multi-layered control framework can be simplified by employing differential flatness for such a system. Finally, the mathematical model of a snake robot moving inside a uniform channel using only side-wall contact is discussed. The model has further been employed to demonstrate adaptive robust control design for such a motion.Using numerous illustrations and tables, Adaptive Robust Control for Planar Snake Robots will interest researchers, practicing engineers and postgraduate students working in the field of robotics and control systems.
