 Power beaming is the ability to move energy without moving or employing mass between an energy input and energy output. It is an emerging technology that could reshape how we generate and distribute energy and how our devices and autonomous systems are powered.This comprehensive compendium provides the foundation needed for researchers, technology developers, and end users to understand the promise and challenges for power beaming. By establishing a common nomenclature and conceptual approach to the analysis and assessment of power beaming systems, this unique reference text provides a true status of advancements in the field, and lays the groundwork for fruitful future research and applications.Contents: <ul><li>Introduction</li><li>History</li><li>Survey of Fundamentals and Conceptual Tools</li><li>Wavelength Selection, Beam Propagation, Safety, and Regulations</li><li>Components and Subsystems for Microwave Power Beaming</li><li>Components and Subsystems for Optical Power Beaming</li><li>Link Characterization</li><li>Power Beaming Applications</li></ul>Readership: Professionals, researchers, academics and graduate students in electrical & electronic engineering.

 'Sustainment' (as commonly defined by industry and government), is comprised of maintenance, support, and upgrade practices that sustain or improve the performance of a system and maximize the availability of goods and services while minimizing their cost and footprint or, more simply, the capacity of a system to endure. Sustainment is a multi-trillion-dollar enterprise for critical systems, in both government (infrastructure and defense) and industry (transportation, industrial controls, data centers, and energy generation).This book is a mix of engineering, operations research, and policy sciences intended to provide students with a thorough understanding of the concept of sustainability and sustainable product life-cycles, and an appreciation of the importance of sustaining critical systems. It starts from the key attributes for system sustainment that includes data analytics, engineering analysis and the public policy needed to support the development of technologies, processes, and frameworks required for the management of sustainable processes and practices. The specific topics covered include: acquisition of critical systems, reliability, maintenance, availability, readiness, inventory management, supply-chain management and risks, contracting for sustainment, and various analysis methodologies (discounted cash flow analysis, discrete-event simulation and Monte Carlo methods). Practice problems are included at the end of each chapter.Contents: <ul><li>Introduction to Sustainment</li><li>The Acquisition of Critical Systems</li><li>System Failure</li><li>Maintenance — Managing System Failure</li><li>Availability and Readiness</li><li>Sustainment Inventory Management</li><li>Supply-Chain Management</li><li>System Sustainment Enablers</li><li>Contracting for Sustainment</li><li>Epilogue — The Future of System Sustainment</li><li>Appendice A: Discounted Cash Flow (DCF) Analysis</li><li>Appendice B: Monte Carlo Analysis</li><li>Appendice C: Discrete-Event Simulation (DES)</li><li>Appendice D: Summary of Notation and Acronyms</li></ul>Readership: This book is intended to be a resource for advanced undergraduate and graduate students in engineering (aerospace, civil, electrical, mechanical, and engineering management), business, and public policy who want to understand the ramifications of, and processes for, system sustainment. It is also a useful reference for industry short courses provided to practicing professionals, whom in many cases, were not introduced to system sustainment during their education and are now thrust into the field with minimal preparation.Key Features:<ul><li>While there are many books that focus on system reliability, there are fewer treatments of the consequences of system unreliability</li><li>The book adopted a holistic view that systems are more than just hardware and software, in addition they are supply chains, workforces, contracts, business models, acquisition processes and governance, if any of these elements fail, might lead to failure of the entire system</li><li>As a result, this book is a mix of engineering, operations research, and policy sciences intended to provide students with an appreciation of the life-cycle costs, consequences, and risks of procuring and sustaining critical systems</li></ul></ul>

de Grazia Lamanna

~~105,64€~~ 95,08€ 10% IMEDIATO

DISPONIBILIDADE IMEDIATA

 This unique compendium revises the most recent thermodynamic theories of supercritical fluids, focusing on the dynamic crossover and the role of thermodynamic properties in controlling this crossover.The volume also critically discusses different transition criteria to predict the onset of single-phase (diffusive) mixing and applies them to transcritical droplets and jets. The book overviews the different types of disintegration regimes and the conditions under which phase separation made be observed, even for supercritical injection conditions.This useful reference text benefits professionals, researchers, academics and graduate students in the fields of aerospace engineering, applied physics, chemical engineering and energy studies.Contents: <ul><li>Introduction</li><li>Experimental Facilities and Diagnostic Methods</li><li>Current Perspectives on the Behavior of Supercritical Fluids</li><li>Two-Phase Flow at High Pressure: A Review</li><li>Droplet Evaporation at High-Pressure</li><li>High-Pressure Disintegration Regimes</li><li>Empirical Correlations Employed in the Young Model</li></ul>Readership: Researchers, professionals, academics, undergraduate and graduate students in aerospace engineering, applied physics and chemical engineering.
