Magnetokalorischer Effekt in Heusler-Legierungen auf Ni-Mn-Basis
Die magnetische K hlung, die sich den magnetokalorischen Effekt zunutze macht, hat sich zu einer konkurrenzf higen Technologie auf dem Gebiet der K ltetechnik entwickelt. Es handelt sich um eine umweltfreundliche Technologie, da sie im Gegensatz zur herk mmlichen Dampfkompressions-/Expansions-K ltetechnik keine gasf rmigen Stoffe ben tigt. Die Leistung eines magnetischen K hlschranks h ngt haupts chlich von der magnetokalorischen Eigenschaft des Stoffes ab. F r die potenzielle Anwendung dieser Technologie besteht ein gro er Bedarf an kosteng nstigen und hocheffizienten magnetokalorischen Materialien als magnetische K ltemittel. Daher ist es notwendig geworden, Materialien zu finden, die einen gro en magnetokalorischen Effekt aufweisen. Heusler-Legierungen sind eine wichtige Materialklasse, die einen gro en magnetokalorischen Effekt aufweist und ihr Potenzial als magnetokalorische Materialien bewiesen hat. Dieses Buch bietet einen kurzen berblick ber den magnetokalorischen Effekt in Heusler-Legierungen auf Ni-Mn-Basis, der Forschern auf diesem Gebiet helfen kann. Die Grundlagen des magnetokalorischen Effekts und seine Messmethoden sowie die Probenvorbereitung werden ebenfalls in diesem Buch behandelt, was f r Anf nger auf diesem Gebiet n tzlich sein kann.

This volume links the concept of granular computing using deep learning and the Internet of Things to object tracking for video analysis. It describes how uncertainties, involved in the task of video processing, could be handled in rough set theoretic granular computing frameworks. Issues such as object tracking from videos in constrained situations, occlusion/overlapping handling, measuring of the reliability of tracking methods, object recognition and linguistic interpretation in video scenes, and event prediction from videos, are the addressed in this volume. The book also looks at ways to reduce data dependency in the context of unsupervised (without manual interaction/ labeled data/ prior information) training.This book may be used both as a textbook and reference book for graduate students and researchers in computer science, electrical engineering, system science, data science, and information technology, and is recommended for both students and practitioners working in computer vision, machine learning, video analytics, image analytics, artificial intelligence, system design, rough set theory, granular computing, and soft computing.

Introduction to Structural Analysis covers the principles of structural analysis without any requirement of prior knowledge of structures or equations. Beginning with basic principles of equilibrium of forces and moments, all other subsequent theories of structural analysis have been discussed logically. Divided into two major parts, this book discusses the basics of mechanics and principles of degrees of freedom upon which the entire paradigm rests, followed by analysis of determinate and indeterminate structures. The energy method of structural analysis is also included. Worked out examples are provided in each chapter to explain the concepts and solve real-life structural analysis problems along with a solutions manual. Aimed at undergraduate and senior undergraduate students in civil, structural, and construction engineering, this book:• Deals with the basic levels of structural analysis (i.e., types of structures and loads, materials and section properties up to the standard level, including analysis of determinate and indeterminate structures).• Focuses on generalized coordinate systems and Lagrangian and Hamiltonian mechanics as an alternative method of studying the subject.• Introduces structural indeterminacy and degrees of freedom with many worked out examples.• Covers fundamentals of matrix theory of structural analysis.• Reviews energy principles and their relationship for calculating structural deflections.• Covers plastic analysis of structures.

Biohydrogen Production: Fundamentals and Technology Advances covers the fundamentals of biohydrogen production technology, including microbiology, biochemistry, feedstock requirements, and molecular biology of the biological hydrogen production processes. It also gives insight into scale-up problems and limitations. In addition, the book discusses mathematical modeling of the various processes involved in biohydrogen production and the software required to model the processes. The book summarizes research advances that have been made in this field and discusses bottlenecks of the various processes, which presently limit the commercialization of this technology. The authors also focus on the process economy, policy, and environmental impact of this technology, since the future of biohydrogen production depends not only on research advances, but also on economic considerations (the cost of fossil fuels), social espousal, and the development of H2 energy systems. The book describes the fundamentals of this technology interwoven with more advanced research findings. Further reading is suggested at the end of each chapter.Since the beauty of any innovation is its applicability, socioeconomic impact, and cost energy analysis, the book examines each of these points to give you a holistic picture of this technology. Illustrative diagrams, flow charts, and comprehensive tables detailing the scientific advancements provide an opportunity to understand the process comprehensively and meticulously. Written in a lucid style, the book supplies a complete knowledge bank about biohydrogen production processes.

This cross-disciplinary field utilizes the strange effects of quantum mechanics to enable information processing and computing that would be impossible on traditional 'classical' computers. The field has developed rapidly over the last few years due in part to its tremendous technological potential. The theoretical foundations of the subject are clearly established and good textbooks are available. However, many experimental directions are under investigation and hardly any book describing them is available on the market. Quantum cryptography, for example, has already evolved to marketable devices. Most of the books on quantum information and/or quantum computing address the important aspect of optical implementation only briefly. This book solves that by focusing on all light-based approaches to quantum computing.
