State of the art resource covering key technologies and related theories of inter-satellite links Inter-Satellite Links Technology explores satellite networking as a growing topic in the field of communication technology, introducing the definition, types, and working frequency bands of inter-satellite links, discussing the number of orbital elements of the spacecraft motion state under two-body motion and their conversion relationship, and establishing the basic demand model for inter-satellite link network, chain topology model, and transmission protocol model. The book focuses on the analysis and introduction of the principles and error sources of microwave and laser inter-satellite ranging, including the basic composition, workflow, and constraints of the laser inter-satellite link, and related design principles of the inter-satellite laser transmitter and receivers. Later chapters also discuss theories and methods of acquisition, alignment, and tracking, the impact of alignment errors on performance, and inter-satellite link modulation and its implementation. Specific sample topics covered in Inter-Satellite Links Technology include: Pulse position modulation (PPM), Differential Pulse Position Modulation (DPPM), Digital Pulse Interval Modulation (DPIM), and Double-head pulse interval modulation (DH-PIM) Basic demand model of inter-satellite link network application, including basic configuration of constellations and inter-satellite transmission networks Inter-satellite ranging accuracy, principles of microwave inter-satellite ranging, and analysis of microwave ranging error sources Effect of tracking error on the beam distribution at the receiving end and influence of tracking and pointing error on communication error rate Inter-Satellite Links Technology serves a completely comprehensive resource on the subject and is a must-have reference for experts and scholars in aerospace, along with graduates and senior undergraduates in related programs of study.

On December 13, 1937, the Japanese army captured Nanjing and we nt on to wantonlymassacre disarmed Chinese soldiers and defenseless civilians in flagrant violation ofinternational conventions. The Nanjing Massacre forms one of the darkest chapters in20th-century world history.Researching this major historical event requires scholars worldwide to collect a variety ofprimary source material in different languages. Compiled by a group of historians fromabout ten universities and research institutions based in China and abroad, Human Memory:Solid Evidence of the Nanjing Massacre represents a major effort in this regard. Consistingof textual and pictorial evidence reproduced from major archives and libraries aroundthe world, the book falls into four parts—Chinese, Japanese, English, and other Westernlanguages. The book covers material created by victims, perpetrators, and important thirdparties in a diversity of formats: diaries, petitions, investig ation reports, news articles,tribunal documents, and photographs. To help readers to better understand the widerange of evidence, the editors have provided very useful annotations for each document orphotograph. Without a doubt, this publication holds some of the most vivid and soberingscenes in humanity’s collective memory.

How can cognition, a concept traditionally associated with the human brain, be applied to satellite systems? For the first time, cognitive system meanings and models are applied to the uncertain environmental processes of satellite systems. The authors of this book go beyond defining 'cognitive satellite systems' to design a cognitive satellite communication system architecture with satellite-to-ground coordination, which has uses in emergency response spacecraft and prediction technology.In this book, the optimal utilization of cognitive satellite system resources is discussed in four aspects:

Build and Deploy Mobile Business Apps That Smoothly Integrate with Enterprise IT For today’s enterprises, mobile apps can have a truly transformational impact. However, to maximize their value, you can’t build them in isolation. Your new mobile apps must reflect the revolutionary mobile paradigm and delight today’s mobile users--but they must also integrate smoothly with existing systems and leverage previous generations of IT investment. In this guide, a team of IBM’s leading experts show how to meet all these goals. Drawing on extensive experience with pioneering enterprise clients, they cover every facet of planning, building, integrating, and deploying mobile apps in large-scale production environments. You’ll find proven advice and best practices for architecture, cloud integration, security, user experience, coding, testing, and much more. Each chapter can stand alone to help you solve specific real-world problems. Together, they help you establish a flow of DevOps activities and lifecycle processes fully optimized for enterprise mobility.
