The effects of very high pressures on various physical systems are of great scientific interest and experiments in this field are an increasingly important activity. Literature on high pressure methods is however scarce and largely out of date. This book is the first to present a broad and thorough coverage of methods and applications. It also provides a technological overview of high-pressure research in the Soviet Union much of which has never been presented in Western literature. This book is intended for graduate students specialising in high pressure experiments in physics, chemistry, and biology, and for scientists coming to high pressure experimentation for the first time as well as those already working in the field.

Fundamental to the control of mechatronic devices, the servomechanism applies feedback from the device in question to regulate its position, velocity, or some other physical attribute. Successful mastery of servo control requires an understanding of a wide range of engineering disciplines, making it difficult and time-consuming to master it all-and even harder to find an all-encompassing guide that shows you how. DC Servos: Application and Design with MATLAB (R) is designed and written with this problem in mind. It breaks down the practical knowledge required from the various branches of applied science-electrical and mechanical engineering, analog electronics, mechanics, control theory, digital electronics, embedded computing, and firmware design-into a cohesive and usable framework. Today, DC servos are working around the world in countless applications-CD players, ink-jet printers, robots, machining centers, vending machines, eyeglass manufacturing machines, home appliances, and automotive seat positioners, just to name a few. This book balances coverage of theoretical and practical aspects of application and design of DC servomechanisms. It also provides detailed coverage of feedback transducers, particularly the application of optical encoders to real systems. It covers how to use the MATLAB (R) Control System Toolbox specifically for servo design, to make the design process faster and more interactive. It also presents two complete, bench-tested reference designs that can be duplicated using readily available parts, so you can build your own servo and see it in action. Author Stephen M. Tobin is an expert in motion control and electro-optical instrumentation and a respected consultant in the medical device and manufacturing automation communities. In order to instill confidence in the engineers, scientists, students, and hobbyists designing the ever more complex machines of the 21st century, Tobin guides the reader on a short journey through "servo school," imparting his lifelong passion for motion control along the way.

This book deals with nonlinear dynamics of electronic circuits, which could be used in robot control, secure communications, sensors and synchronized networks. The genesis of the content is related to a course on complex adaptive systems that has been held at the University of Catania since 2005. The efforts are devoted in order to emulate with nonlinear electronic circuits nonlinear dynamics. Step-by-step methods show the essential concepts of complex systems by using the Varela diagrams and accompanying MATLAB (R) exercises to reinforce new information. Special attention has been devoted to chaotic systems and networks of chaotic circuits by exploring the fundamentals, such as synchronization and control. The aim of the book is to give to readers a comprehensive view of the main concepts of nonlinear dynamics to help them better understand complex systems and their control through the use of electronics devices.

Do you have a smartphone? Billions of people on the planet now navigate their daily lives with the kind of advanced Global Positioning System capabilities once reserved for the most secretive elements of America's military-industrial complex. But when so many people have access to the most powerful technologies humanity has ever devised for the precise determination of geographical coordinates, do we still need a specialized field of knowledge called geography?Just as big data and artificial intelligence promise to automate occupations ranging from customer service and truck driving to stock trading and financial analysis, our age of algorithmic efficiency seems to eliminate the need for humans who call themselves geographers-at the precise moment when engaging with information about the peoples, places, and environments of a diverse world is more popular than ever before. How did we get here? This book traces the recent history of geography, information, and technology through the biography of Edward A. Ackerman, an important but forgotten figure in geography's "quantitative revolution." It argues that Ackerman's work helped encode the hidden logics of a distorted philosophical heritage-a dangerous, cybernetic form of thought known as militant neo-Kantianism-into the network architectures of today's pervasive worlds of surveillance capitalism.

Impedance Spectroscopy is a powerful measurement method used in many application fields such as electrochemistry, material science, biology and medicine, semiconductor industry and sensors.

This book is the fifth in the series Lecture Notes on Impedance Spectroscopy (LNIS). The series covers new advances in the field of impedance spectroscopy including fundamentals, methods and applications. It releases scientific contributions as extended chapters including detailed information about recent scientific research results. This book is including proceedings of the International Workshop on Impedance Spectroscopy (IWIS) which has been launched already in June 2008 with the aim to serve as a platform for specialists in this field.

This book is interesting for graduated students, engineers, researchers and specialists dealing with impedance spectroscopy. It includes fundamentals of impedance spectroscopy as well as specific aspects form manifold applications in various fields.

Networked Control Systems (NCSs) are spatially distributed systems for which the communication between sensors, actuators and controllers is realized by a shared (wired or wireless) communication network. NCSs offer several advantages, such as reduced installation and maintenance costs, as well as greater flexibility, over conventional control systems in which parts of control loops exchange information via dedicated point-to-point connections. The principal goal of this book is to present a coherent and versatile framework applicable to various settings investigated by the authors over the last several years. This framework is applicable to nonlinear time-varying dynamic plants and controllers with delayed dynamics; a large class of static, dynamic, probabilistic and priority-oriented scheduling protocols; delayed, noisy, lossy and intermittent information exchange; decentralized control problems of heterogeneous agents with time-varying directed (not necessarily balanced) communication topologies; state- and output-feedback; off-line and on-line intermittent feedback; optimal intermittent feedback through Approximate Dynamic Programming (ADP) and Reinforcement Learning (RL); and control systems with exogenous disturbances and modeling uncertainties.
