SMART MATERIALS FOR SCIENCE AND ENGINEERING Smart materials, also known as advanced or creative materials, are described as advanced materials that react intuitively to environmental changes or as materials that can return to their original shape in response to certain stimuli. Smart materials are classified as either active or passive based on their characteristics. There are two types of active materials. The first kind cannot change its characteristics when subjected to outside stimuli, for example photochromatic spectacles that only alter their color when exposed to sunlight. The other, which includes piezoelectric materials, can change one sort of energy (thermal, electrical, chemical, mechanical, or optical) into another. When subjected to external pressure, it can generate an electric charge. As an example, optical fibers can transmit electromagnetic waves. In contrast, passive smart materials can transmit a specific sort of energy. They have some amazing qualities that set them apart from other materials, such as transiency, meaning they can react to different kinds of external stimuli immediately, self-actuation or the capacity to change their appearance and shape, selectivity where the response is divided and expected, directness when the response is limited to the activating event, shape-changing where the material can change its shape to external stimuli, their ability to determine their own health, also known as self-diagnosis, and their ability to self-heal. The ability to synthesize novel materials has substantially progressed thanks to science and technology over the past 20 years. They fall mostly into the following four categories: polymers, ceramics, metals, and smart materials. Among these, smart materials are gaining popularity since they have more uses than conventional materials. Smart materials are unusual substances that have the ability to alter their properties, such as those that can immediately change their phase when placed near a magnet or their shape simply by applying heat. Humanity will be significantly impacted by this new era of smart materials. For instance, some of them can adapt their properties to the environment, some have sensory capabilities, some can repair themselves automatically, and some can degrade themselves. These extraordinary properties of smart materials will have an effect on all facets of civilization. There are many different types of intelligent materials, including magnetorheological materials, electro-rheostat materials, shape memory alloys, piezoelectric materials, and more. This book describes many forms of smart materials and their possible uses in various fields. A literature survey discusses the different types of smart materials, such as based ceramics, polymers, and organic compounds and their needs, advantages, disadvantages, and applications will be comprehensively discussed. A discussion of well-established smart materials including piezoelectric, magnetostrictive, shape memory alloy, electro-rheological fluid, and magnetorheological fluid materials will be discussed with their present prospects.

The concepts of the Electron Statistics (ES) and the ES dependent electronic properties are basic pillars in semiconductor electronics and this first-of-its-kind book deals with the said concepts in doping superlattices (SLs), quantum well, quantum wire and quantum dot SLs, effective mass SLs, SLs with graded interfaces and Fibonacci SLs under different physical conditions respectively. The influences of intense radiation and strong electric fields under said concepts have been considered together with the heavily doped SLs in this context on the basis of newly formulated the electron energy spectra in all the cases. We have suggested experimental determinations of the Einstein relation for the Diffusivity-Mobility ratio, the Debye screening length, Elastic Constants and the content of this book finds 25 different applications in the arena of nanoscience and nanotechnology.This book contains hundred open research problems which form the integral part of the text and are useful for both PhD aspirants and researchers. It is written for post graduate students of various departments of different academic organizations, engineers and professionals in the fields of solid state electronics, materials science, solid state sciences, nano-science, nanotechnology and nano materials in general.

This book constitutes selected revised and extended papers from the 10th International Conference on High-Performance Computing Systems and Technologies in Scientific Research, Automation of Control and Production, HPCST 2020, Barnaul, Russia, in May 2020. Due to the COVID-19 pancemic the conference was partly held in virtual mode. The 14 full papers presented in this volume were thoroughly reviewed and selected form 51 submissions. The papers are organized in topical sections on hardware for high-performance computing and its applications; information technologies and computer simulation of physical phenomena.

Modern power and energy systems are characterized by the wide integration of distributed generation, storage and electric vehicles, adoption of ICT solutions, and interconnection of different energy carriers and consumer engagement, posing new challenges and creating new opportunities. Advanced testing and validation methods are needed to efficiently validate power equipment and controls in the contemporary complex environment and support the transition to a cleaner and sustainable energy system. Real-time hardware-in-the-loop (HIL) simulation has proven to be an effective method for validating and de-risking power system equipment in highly realistic, flexible, and repeatable conditions. Controller hardware-in-the-loop (CHIL) and power hardware-in-the-loop (PHIL) are the two main HIL simulation methods used in industry and academia that contribute to system-level testing enhancement by exploiting the flexibility of digital simulations in testing actual controllers and power equipment. This book addresses recent advances in real-time HIL simulation in several domains (also in new and promising areas), including technique improvements to promote its wider use. It is composed of 14 papers dealing with advances in HIL testing of power electronic converters, power system protection, modeling for real-time digital simulation, co-simulation, geographically distributed HIL, and multiphysics HIL, among other topics.

This book addresses the rapidly developing class of solar cell materials and designed to provide much needed information on the fundamental principles of these materials, together with how these are employed in photovoltaic applications. A special emphasize have been given for the space applications through study of radiation tolerant solar cells. This book present a comprehensive research outlining progress on the synthesis, fabrication and application of solar cells from fundamental to device technology and is helpful for graduate students, researchers, and technologists engaged in research and development of materials.
