Les progr s rapides de l'industrie a rospatiale ont impos des exigences accrues la science des mat riaux. Les alliages d'aluminium, en tant que mat riau structurel l ger important, ont fait l'objet d'une grande attention dans ce domaine. Pour r pondre aux conditions strictes de l'a rospatiale, des alliages d'aluminium Al-Cu-Mg et Al-Zn-Mg haute r sistance, haute t nacit , tr s r sistants la corrosion et faciles traiter sont principalement d velopp s. Ce livre vise tudier les applications des alliages d'aluminium Al-Cu-Mg typiques dans le domaine de l'a rospatiale, en discutant des propri t s des mat riaux, de la conception des alliages, des techniques de fabrication, de l' valuation des performances, tout en anticipant les perspectives de d veloppement des alliages d'aluminium dans le domaine de l'a rospatiale.Ce livre peut tre utilis comme manuel pour les tudiants de troisi me cycle en science et ing nierie des mat riaux, ainsi que pour les tudiants de premier cycle en science des mat riaux. Il peut galement servir d'ouvrage de r f rence pour le personnel technique et d'ing nierie.

The rapid advancement of the aerospace industry has imposed greater demands on materials science. Aluminum alloys, as an important lightweight structural material, have drawn wide attention in this field. To meet the strict conditions in aerospace, high-strength, high-toughness, highly corrosion-resistant, and easily processable Al-Cu-Mg and Al-Zn-Mg aluminum alloys are mainly developed. This book aims to investigate the application research of typical Al-Cu-Mg aluminum alloys in the field of aerospace, discussing material properties, alloy design, fabrication techniques, performance evaluation while also anticipating future development prospects for aluminum alloys in aerospace.The book can be used as a textbook for graduate students majoring in Materials Science and Engineering, as well as for undergraduate students majoring in Materials Science. It can also serve as a reference book for engineering and technical personnel.

This book includes 43 case studies showcasing the application of basic education informatization. It shares the experiences of 43 schools in the construction and application of educational informatization in various regions in China. It aims to promote the balanced development of education and expand the coverage of quality education resources. This book also highlights the achievements of these schools in constructing school-based resources, and changing teaching modes and optimizing classroom teaching. This collection of case studies not only reflects the current trend of informatization application moving from 'universal application' to 'integrated innovation' but also uncovers the potential of applying information technology to transform education processes, innovate education environment, and optimize education governance.

A RAND study analyzed Chinese and U.S. military capabilities in two scenarios (Taiwan and the Spratly Islands) from 1996 to 2017, finding that trends in most, but not all, areas run strongly against the United States. While U.S. aggregate power remains greater than China s, distance and geography affect outcomes. China is capable of challenging U.S. military dominance on its immediate periphery and its reach is likely to grow in the years ahead."

Signals and systems enjoy wide application in industry and daily life, and understanding basic concepts of the subject area is of importance to undergraduates majoring in engineering. With rigorous mathematical deduction, this introductory text book is helpful for students who study communications engineering, electrical and electronic engineering, and control engineering. Additionally, supplementary materials are provided for self-learners.

This book introduces the concepts and models of robust representation learning, and provides a set of solutions to deal with real-world data analytics tasks, such as clustering, classification, time series modeling, outlier detection, collaborative filtering, community detection, etc. Three types of robust feature representations are developed, which extend the understanding of graph, subspace, and dictionary.Leveraging the theory of low-rank and sparse modeling, the authors develop robust feature representations under various learning paradigms, including unsupervised learning, supervised learning, semi-supervised learning, multi-view learning, transfer learning, and deep learning. Robust Representations for Data Analytics covers a wide range of applications in the research fields of big data, human-centered computing, pattern recognition, digital marketing, web mining, and computer vision.

Silicon on Insulator is more than a technology, more than a job, and more than a venture in microelectronics; it is something different and refreshing in device physics. This book recalls the activity and enthu­ siasm of our SOl groups. Many contributing students have since then disappeared from the SOl horizon. Some of them believed that SOl was the great love of their scientific lives; others just considered SOl as a fantastic LEGO game for adults. We thank them all for kindly letting us imagine that we were guiding them. This book was very necessary to many people. SOl engineers will certainly be happy: indeed, if the performance of their SOl components is not always outstanding, they can now safely incriminate the relations given in the book rather than their process. Martine, Gunter, and Y. S. Chang can contemplate at last the amount of work they did with the figures. Our SOl accomplices already know how much we borrowed from their expertise and would find it indecent to have their detailed contri­ butions listed. Jean-Pierre and Dimitris incited the book, while sharing their experience in the reliability of floating bodies. Our families and friends now realize the SOl capability of dielectrically isolating us for about two years in a BOX. Our kids encouraged us to start writing. Our wives definitely gave us the courage to stop writing. They had a hard time fighting the symptoms of a rapidly developing SOl allergy.
