![]() Free Download Spatial Optical-Fiber Coupling Technology in Optical-Wireless Communication (Optical Wireless Communication Theory and Technology) by Xizheng Ke English | July 3, 2023 | ISBN: 9819915244 | 236 pages | MOBI | 30 Mb This book analyzes the development of space light-fiber coupling research, highlights its importance, examines the underlying theory and key problems, and elaborates on methods to improve the space light-fiber coupling efficiency. Starting from the basic theory of electromagnetic field, the transmission characteristics of light in optical fibers are expounded, and the coupling characteristics of optical signals of different modes are investigated. The spatial light-fiber coupling techniques such as mode conversion method, lens coupling method, and wavefront distortion correction method are discussed in detail, and the key technologies involved are verified by experiments. This book is suitable for the vast majority of engineering and technical personnel and teachers in colleges and institutions who are engaged in wireless optical communication. It can also be used to train senior undergraduates and graduate students in relevant fields. ![]() Free Download Spanish For Dummies, 3rd Edition by Cecie Kraynak English | May 12th, 2025 | ISBN: 1394321325 | 387 pages | True PDF | 6.25 MB Learn to speak Latin American Spanish with confidence-the easy way ![]() Free Download Space-Air-Ground Integrated Network Security by Jianwei Liu, Lin Bai, Chunxiao Jiang English | June 20, 2023 | ISBN: 9819911249 | 438 pages | MOBI | 44 Mb This book focuses on security science and technology, data and information security, and mobile and network security for space-air-ground integrated networks (SAGINs). SAGIN are expected to play an increasingly important role in providing real-time, flexible, and integrated communication and data transmission services in an efficient manner. Today, SAGINs have been widely developed for a range of applications in navigation, environmental monitoring, traffic management, counter-terrorism, etc. However, security becomes a major concern, since the satellites, spacecrafts, and aircrafts are susceptible to a variety of traditional/specific network-based attacks, including eavesdropping, session hijacking, and illegal access. ![]() Free Download Soziale Ungleichheit By Thomas Schwinn 2015 | 166 Pages | ISBN: 3839405920 | PDF | 1 MB Die Theorie sozialer Ungleichheit hat seit den Klassikern der Soziologie keine großen Fortschritte zu verzeichnen. In den einschlägigen Studien dominiert eine auflistende Aneinanderreihung von einzelnen Ansätzen. Es fehlt bisher jedoch eine Theorie sozialer Ungleichheit, die auf der Höhe der aktuellen gesellschaftstheoretischen Diskussion ist.Diese Einführung arbeitet hierzu den Anschluss an die Theorie gesellschaftlicher Differenzierung heraus. Durch die konzeptionelle Integration der beiden makrosozialen Hauptachsen lassen sich viele Aspekte sozialer Ungleichheit angemessen erklären: strukturierte versus unstrukturierte soziale Ungleichheit; das Verhältnis von klassen-, ethnischer und geschlechtsspezifischer Ungleichheit; die Transnationalisierung sozialer Ungleichheit sowie soziale Ungleichheiten auf verschiedenen Aggregationsebenen (Interaktion, Organisation, Ordnung). ![]() Free Download Southeast Asian Studies: Debates and New Directions By Cynthia Chou (editor); Vincent Houben (editor) 2006 | 216 Pages | ISBN: 981230651X | PDF | 1 MB "What is the relevance of the area studies approach to Southeast Asia?" The current state and future directions of area studies, of which Southeast Asian studies are a part, is a central question not only to scientists working in the field but also those engaged in university politics. This collection of nine articles is written by specialists from different disciplinary backgrounds and working in institutions of higher learning all around the world. It provides an up-to-date insight into the current state of the study field, its strengths and weaknesses and seeks ways to reconfigure Southeast Asian studies in order to meet the challenges of a region that is caught up in profound transformation as a consequence of both globalization and localization. ![]() Free Download Sourdough Discord Recipes Cookbook: Tips, Techniques, and Recipes from the Sourdough Baker by Tammy Skeldon English | October 26, 2024 | ISBN: N/A | ASIN: B0DL4CVL4J | 83 pages | PDF | 1.02 Mb Sourdough Discord Recipes Cookbook ![]() Free Download Sounds of a New Generation: On Contemporary Jewish-American Literature By Deborah Wallrabenstein 2017 | 204 Pages | ISBN: 3839439868 | PDF | 1 MB This book offers insight into the approaches of a new generation of Jewish-American writers. Whether they reimagine their ancestors' "shtetl life" or invent their own kind of Jewishness, they have a common curiosity in what makes them Jewish. Is it because most of them are third-generation Americans who don't worry about assimilation as their parents' generation did? If so, how does the writing of recent Jewish immigrants from the former Soviet Union fit into the picture? Unlike Irving Howe predicted in 1977, Jewish-American literature did not fade after immigration. It always finds new paths, drawing from the vast scope of Jewish life in America. ![]() Free Download Some Tapas of Computer Algebra by Arjeh M. Cohen, Hans Cuypers, Hans Sterk English | PDF | 1999 | 365 Pages | ISBN : 3540634800 | 29.3 MB In the years 1994, 1995, two EIDMA mini courses on Computer Algebra were given at the Eindhoven University of Technology by, apart from ourselves, various invited lecturers. (EIDMA is the Research School 'Euler Institute for Discrete Mathematics and its Applications'.) The idea of the courses was to acquaint young mathematicians with algorithms and software for mathemat ical research and to enable them to incorporate algorithms in their research. A collection of lecture notes was used at these courses. When discussing these courses in comparison with other kinds of courses one might give in a week's time, Joachim Neubüser referred to our courses as 'tapas'. This denomination underlined that the courses consisted of appe tizers for various parts of algorithmic algebra; indeed, we covered such spicy topics as the link between Gröbner bases and integer programming, and the detection of algebraic solutions to differential equations. As a collection, the not es turned out to have some appeal of their own, which is the main reason why the idea came up of transforming them into book form. We feIt however, that the book should be distinguishable from a standard text book on computer algebra in that it retains its appetizing flavour by presenting a variety of topics at an accessible level with a view to recent developments. ![]() Free Download Somatic Exercises For Dummies by Kristin McGee English | May 6th, 2025 | ISBN: 1394298218 | 384 pages | True EPUB | 21.57 MB Reduce stress, relieve pain, and improve your overall health with somatic exercise ![]() Free Download Solving Differential Equations in R by Karline Soetaert English | EPUB | 2012 | 258 Pages | ISBN : 3642280692 | 271.7 MB Mathematics plays an important role in many scientific and engineering disciplines. This book deals with the numerical solution of differential equations, a very important branch of mathematics. Our aim is to give a practical and theoretical account of how to solve a large variety of differential equations, comprising ordinary differential equations, initial value problems and boundary value problems, differential algebraic equations, partial differential equations and delay differential equations. |
