Topologies of Power amounts to a radical departure in the way that power and space have been understood. It calls into question the very idea that power is simply extended across a given territory or network, and argues that power today has a new found ‘reach’. Topological shifts have subtly altered the reach of power, enabling governments, corporations and NGOs alike to register their presence through quieter, less brash forms of power than domination or overt control. In a world in which proximity and distance increasingly play across one another, topology offers an insight into how power remains continuous under transformation: the same but different in its ability to shape peoples’ lives. Drawing upon a range of political, economic and cultural illustrations, the book sets out a clear and accessible account of the topological workings of power in the contemporary moment. It will be invaluable for both students and academics in human geography, politics, sociology, and cultural studies.

This thesis proposes new power converter topologies suitable for aircraft systems. It also proposes both AC-DC and DC-DC types of converters for different electrical loads to improve the performance these systems. To increase fuel efficiency and reduce environmental impacts, less efficient non-electrical aircraft systems are being replaced by electrical systems. However, more electrical systems requires more electrical power to be generated in the aircraft. The increased consumption of electrical power in both civil and military aircrafts has necessitated the use of more efficient electrical power conversion technologies. This book presents acomprehensive mathematical analysis and the design and digital simulation of the power converters. Subsequently it discusses the construction of the hardware prototypes of each converter and the experimental tests carried out to verify the benefits of the proposed solutions in comparison to the existing solutions.

Effective software teams are essential for any organization to deliver value continuously and sustainably. But how do you build the best team organization for your specific goals, culture, and needs? Team Topologies is a practical, step-by-step, adaptive model for organizational design and team interaction based on four fundamental team types and three team interaction patterns. It is a model that treats teams as the fundamental means of delivery, where team structures and communication pathways are able to evolve with technological and organizational maturity. In Team Topologies, IT consultants Matthew Skelton and Manuel Pais share secrets of successful team patterns and interactions to help readers choose and evolve the right team patterns for their organization, making sure to keep the software healthy and optimize value streams. Team Topologies is a major step forward in organizational design for software, presenting a well-defined way for teams to interact and interrelate that helps make the resulting software architecture clearer and more sustainable, turning inter-team problems into valuable signals for the self-steering organization.

While most books approach power electronics and renewable energy as two separate subjects, Power Electronics for Renewable and Distributed Energy Systems takes an integrative approach; discussing power electronic converters topologies, controls and integration that are specific to the renewable and distributed energy system applications. An overview of power electronic technologies is followed by the introduction of various renewable and distributed energy resources that includes photovoltaics, wind, small hydroelectric, fuel cells, microturbines and variable speed generation. Energy storage systems such as battery and fast response storage systems are discussed along with application-specific examples. After setting forth the fundamentals, the chapters focus on more complex topics such as modular power electronics, microgrids and smart grids for integrating renewable and distributed energy. Emerging topics such as advanced electric vehicles and distributed control paradigm for power system control are discussed in the last two chapters. With contributions from subject matter experts, the diagrams and detailed examples provided in each chapter make Power Electronics for Renewable and Distributed Energy Systems a sourcebook for electrical engineers and consultants working to deploy various renewable and distributed energy systems and can serve as a comprehensive guide for the upper-level undergraduates and graduate students across the globe.

Power Electronics: Modelling, Analysis and Measurements This volume 2 provides papers published by Caltech Power Electronics Group It summarizes the development of modelling and analysis methods culminating in the formulation of the general State-Space Averaging Method as well as accompanying measurement techniques. The Cuk converter covered in all four volumes was the key motivation owing to its floating capacitor and respective capacitive energy transfer requiring additional charge-balance on capacitors. This was missing from the buck and boost converters which required volt-second balance on inductors only. The key insight of the new State-Space Averaging Method was that the DC and AC models could be formulated in general without resort to any particular connection of the switches, inductors, capacitors and transformers. The accompanying measurement techniques describe how the loop-gain frequency response could be measured without breaking the feedback loop. A number of practical design examples of application of modelling and measurement techniques is used to illustrate both methods.

Multilevel Inverters: Topologies, Control Methods, and Applications investigates modern device topologies, control methods, and application areas for the rapidly developing conversion technology. The device topologies section begins with conventional two-level inverter topologies to provide a background on the DC-AC power conversion process and required circuit configurations. Thereafter, multilevel topologies originating from neutral point clamped topologies are presented in detail. The improved and inherited regular multilevel topologies such as flying capacitor and conventional H-bridge topology are presented to illustrate the multilevel concept. Emerging topologies are introduced regarding application areas such as renewable energy sources, electric vehicles, and power systems. The book goes on to discuss fundamental operational principles of inverters using the conventional pulse width modulated control method. Current and voltage based closed loop control methods such as repetitive control, space vector modulation, proportional resonant control and other recent methods are developed. Core modern applications including wind energy, photovoltaics, microgrids, hybrid microgrids, electric vehicles, active filters, and static VAR compensators are investigated in depth. Multilevel Inverters for Emergent Topologies and Advanced Power Electronics Applications is a valuable resource for electrical engineering specialists, smart grid specialists, researchers on electrical, power systems, and electronics engineering, energy and computer engineers. Reviews mathematical modeling and step-by-step simulation examples, straddling both basic and advanced topologies Assesses how to systematically deploy and control multilevel power inverters in application scenarios Reviews key applications across wind energy, photovoltaics, microgrids, hybrid microgrids, electric vehicles, active filters, static VAR compensators

The Soviet Union created a unique form of urban modernity, developing institutions of social provisioning for hundreds of millions of people in small and medium-sized industrial cities spread across a vast territory. After the collapse of socialism these institutions were profoundly shaken--casualties, in the eyes of many observers, of market-oriented reforms associated with neoliberalism and the Washington Consensus. In Post-Soviet Social, Stephen Collier examines reform in Russia beyond the Washington Consensus. He turns attention from the noisy battles over stabilization and privatization during the 1990s to subsequent reforms that grapple with the mundane details of pipes, wires, bureaucratic routines, and budgetary formulas that made up the Soviet social state. Drawing on Michel Foucault's lectures from the late 1970s, Post-Soviet Social uses the Russian case to examine neoliberalism as a central form of political rationality in contemporary societies. The book's basic finding--that neoliberal reforms provide a justification for redistribution and social welfare, and may work to preserve the norms and forms of social modernity--lays the groundwork for a critical revision of conventional understandings of these topics.
