This book explores the mechanisms and applications of acoustic metasurfaces in the hypersonic transition control area. It begins with an introduction of the concepts of acoustic metasurface and hypersonic boundary-layer stabilization, which also provides a full scene of the research progress in the past two decades. This book then discusses the modeling methods of various acoustic metasurfaces, including the regular and irregular ones, and describes how the models are to be used in theoretical analysis and numerical calculations. The design strategies and optimization methods are presented to promote the applications in the engineering community. The possible stabilization mechanisms are explored, and the proposed analysis methods are used to clarify other flow instabilities. This book delivers valuable insight for aerospace engineers, postgraduate students, and researchers.

This book focuses on cellular Vehicle-to-Everything (C-V2X), currently the most promising wireless communication technology for Vehicle-to-Vehicle (V2V), Vehicle-to-Infrastructure (V2I), Vehicle-to-Pedestrian (V2P), Vehicle-to-Network (V2N) and Vehicle-to-Cloud (V2C) communications. Because of its low latency and high reliability, C-V2X has become an essential enabling technology for Intelligent Transportation Systems (ITSs) and autonomous driving. This book begins by introducing readers to the research background and status quo of global development. Then, after analyzing the performance requirements of various V2X applications, the system architecture and technical standards are presented. The two evolving stages of C-V2X, i.e., LTE-V2X and NR-V2X, are introduced in detail. In addition, related technologies such as mobile edge computing, network slicing and high-precision positioning, C-V2X security, C-V2X spectrum requirements and planning, and industrial development andapplications are introduced. In closing, the book discusses future applications of and technical challenges for C-V2X. This book is the first monograph dedicated to C-V2X, offering experts, researchers and engineers from the areas of IT/CT, intelligent transportation, intelligent and connected vehicles (ICVs) an in-depth understanding of C-V2X technology and standards, while also outlining related interdisciplinary research. The book can also be used as a reference resource for both undergraduate and graduate studies.

This book applies multi-criteria decision-making (MCDM) approaches to facilitate sustainable consumption and production. Sustainable consumption and production not only focuses on the economic prosperity but also pays great attention to environmental protection and social justice, in order to promote sustainable development. In such context, most ‘material’ can be deemed as ‘hazardous’ at any stage of their lifecycle, i.e., from extraction to final disposal, because of its quantity, concentration, or physical, chemical, or infectious characteristics, may cause, or pose a substantial or potential hazard to human health or the environment. Through the application of system theory, game theory, optimization theory, as well as various computational approaches, this book helps engineers/ policy makers to identify solutions or mitigation strategies to reduce environmental impact associated with consumption and production. It is essential reading for students, researchers, policy makers as well as those with a wider interest in environmental science and sustainable development.

This book focuses on the behavioral interactions among possible stakeholders in carbon labeling practice, brings the attentions of stakeholders’ interests to explore the opportunities, and challenges related to carbon labeling practice, thus to provide insight into low-carbon consumption and production. It is essential reading for students, researchers, and policy makers as well as those with a wider interest in environmental science and sustainable development.

Motif ist eine Software-Umgebung zur Implementierung grafischer Benutzungsoberfl{chen. Mit Motif erstellte Applikationen enthalten alle Elemente, die eine moderne Benutzungsoberfl{che auszeichnen, wie }berlappende Windows, Dialogboxen und Men}s. Motif ist f}r UNIX und VMS erh{ltlich und hat gute Chancen, Standard f}r diese Betriebssysteme zu werden. Motif besteht aus einem Toolkit, einer Beschreibungssprache, einem Window Manager und einem Style Guide. In diesem Buch wird die Programmierung von Applikationen mit Hilfe des Motif-Toolkits beschrieben. Das Motif-Toolkit stellt Grundbausteine f}r grafische Benutzungsoberfl{chen zur Verf}gung, die sogenannten Widgets. Es baut dabei auf dem X-Window-System und den X-Toolkit-Intrinsics des MIT auf. Das Toolkit deckt aber nicht alle Aspekte einer Applikation ab. Daher werden auch die notwendigen Kenntnisse }ber X und die Intrinsics vermittelt, ohne die eine erfolgreiche Motif-Applikation nicht realisiert werden kann. Das auf die Praxis zugeschnittene Buch wendet sich an all diejenigen, die Applikationen mit grafischen Benutzungsoberfl{chen entwickeln wollen. Die Konzepte des Toolkits werden anhand realistischer Beispiele vorgestellt. Dabei werden Grund-Schemata entwickelt, die auch auf andere Motif-Applikationen anwendbar sind.
