Book Description
An accessible illustrated introducton to the networks we use every day, from Facebook and Google to WiFi and the Internet What makes WiFi faster at home than at a coffee shop? How does Google order search results? Is it really true that everyone on Facebook is connected by six steps or less? The Power of Networks answers questions like these for the first time in a way that all of us can understand. Using simple language, analogies, stories, hundreds of illustrations, and no more math than simple addition and multiplication, Christopher Brinton and Mung Chiang provide a smart and accessible introduction to the handful of big ideas that drive the computer networks we use every day. The Power of Networks unifies these ideas through six fundamental principles of networking. These principles explain the difficulties in sharing network resources efficiently, how crowds can be wise or not so wise depending on the nature of their connections, why there are many layers in a network, and more. Along the way, the authors also talk with and share the special insights of renowned experts such as Google’s Eric Schmidt, former Verizon Wireless CEO Dennis Strigl, and “fathers of the Internet” Vint Cerf and Bob Kahn.

Book Description
Celebrated scientists Nicholas Christakis and James Fowler explain the amazing power of social networks and our profound influence on one another's lives. Your colleague's husband's sister can make you fat, even if you don't know her. A happy neighbor has more impact on your happiness than a happy spouse. These startling revelations of how much we truly influence one another are revealed in the studies of Dr. Christakis and Fowler, which have repeatedly made front-page news nationwide. In Connected, the authors explain why emotions are contagious, how health behaviors spread, why the rich get richer, even how we find and choose our partners. Intriguing and entertaining, Connected overturns the notion of the individual and provides a revolutionary paradigm-that social networks influence our ideas, emotions, health, relationships, behavior, politics, and much more. It will change the way we think about every aspect of our lives.

Book Description
Something new and important is afoot. Nonprofit and philanthropic organizations are under increasing pressure to do more and to do better to increase and improve productivity with fewer resources. Social entrepreneurs, community-minded leaders, nonprofit organizations, and philanthropists now recognize that to achieve greater impact they must adopt a network-centric approach to solving difficult problems. Building networks of like-minded organizations and people offers them a way to weave together and create strong alliances that get better leverage, performance, and results than any single organization is able to do. While the advantages of such networks are clear, there are few resources that offer easily understandable, field-tested information on how to form and manage social-impact networks. Drawn from the authors’ deep experience with more than thirty successful network projects, Connecting to Change the World provides the frameworks, practical advice, case studies, and expert knowledge needed to build better performing networks. Readers will gain greater confidence and ability to anticipate challenges and opportunities. Easily understandable and full of actionable advice, Connecting to Change the World is an informative guide to creating collaborative solutions to tackle the most difficult challenges society faces.

Book Description
The power engineering domain is facing huge challenges, with an increasing interest in intermittent renewable energies which are imposing major technical limitations. Operating ever closer to their limits, the industry-standard AC power grids are subject to instabilities. This book presents an insight into DC grid systems, offering interesting issues to well controlled power grids, in contrast to current AC systems which provide the simplest and most economic connection method for short distances.

Book Description
The work in this thesis proposes the innovative use of modern technologies and mathematical techniques to analyse and control future power systems. It exploits new enabling technologies such as Voltage Source Converter High Voltage Direct Current (VSC-HVDC) lines, both single and multi-terminal, and Wide Area Measurement Systems (WAMS) to reduce the risks of instability associated with greater utilisation of modern power systems. New control systems for these technologies have been analysed, and subsequently designed, using advanced probabilistic analysis techniques to ensure that they are robust to the variable and turbulent conditions expected in the future. The advanced probabilistic techniques used in the thesis for both system analysis and controller design represent one of the first such applications in open literature.

Book Description
When the five Central Asian republics gained independence from the Soviet Union in 1991, expectations of violent conflict were widespread. Indeed, the country of Tajikistan suffered a five-year civil war from 1992 to 1997. The factors that the literature on civil wars in general and on the Tajikistan civil war in particular cites as the causes of war were also present in Uzbekistan – but this country had a peaceful transition. Examining this empirical puzzle by isolating the crucial factors that caused war to break out in Tajikistan but not Uzbekistan, this book applies a powerful comparative approach to the broader question of why civil wars occur. Based on fieldwork in both countries, it challenges many common explanations of civil war both generally and in Tajikistan in particular. This includes highlighting the importance of elites’ power perceptions, which have their origins in the interaction of structural-, process-, and network-related variables. Without examining these interactions, macro-structural explanations alone cannot explain the occurrence of civil war in one country and its absence in another. Applying the insights of bargaining theories of war from the literature on international relations to the civil war in Tajikistan, this book will be of interest to students of violent conflict, civil wars, Central Asia and Asian Politics.

Book Description
Repairable flow networks are a new area of research, which analyzes the repair and flow disruption caused by failures of components in static flow networks. This book addresses a gap in current network research by developing the theory, algorithms and applications related to repairable flow networks and networks with disturbed flows. The theoretical results presented in the book lay the foundations of a new generation of ultra-fast algorithms for optimizing the flow in networks after failures or congestion, and the high computational speed creates the powerful possibility of optimal control of very large and complex networks in real time. Furthermore, the possibility for re-optimizing the network flows in real time increases significantly the yield from real production networks and reduces to a minimum the flow disruption caused by failures. The potential application of repairable flow networks reaches across many large and complex systems, including active power networks, telecommunication networks, oil and gas production networks, transportation networks, water supply networks, emergency evacuation networks, and supply networks. The book reveals a fundamental flaw in classical algorithms for maximising the throughput flow in networks, published since the creation of the theory of flow networks in 1956. Despite the years of intensive research, the classical algorithms for maximising the throughput flow leave highly undesirable directed loops of flow in the optimised networks. These flow loops are associated with wastage of energy and resources and increased levels of congestion in the optimised networks. - Includes theory and practical examples to build a deep understanding of the issues - Written by the leading scholar and researcher in this emerging field - Features powerful software tools for analysis, optimization and control of repairable flow networks
