System-level design techniques for energy-efficient embedded systems
System-Level Design Techniques for Energy-Efficient Embedded Systems addresses the development and validation of co-synthesis techniques that allow an effective design of embedded systems with low energy dissipation. The book provides an overview of a system-level co-design flow, illustrating through examples how system performance is influenced at various steps of the flow including allocation, mapping, and scheduling. The book places special emphasis upon system-level co-synthesis techniques for architectures that contain voltage scalable processors, which can dynamically trade off between computational performance and power consumption. Throughout the book, the introduced co-synthesis techniques, which target both single-mode systems and emerging multi-mode applications, are applied to numerous benchmarks and real-life examples including a realistic smart phone.
Sub-threshold Design for Ultra-Low Power Systems
Although energy dissipation has improved with each new technology node, because SoCs are integrating tens of million devices on-chip, the energy ex pended per operation has become a critical consideration in digital and ana log integrated circuits. The focus of this book is sub-threshold circuit design, which involves scaling voltages below the device thresholds.
Protection of future electricity systems
The electrical energy industry is undergoing dramatic changes: massive deployment of renewables, increasing share of DC networks at transmission and distribution levels, and at the same time, a continuing reduction in conventional synchronous generation, all contribute to a situation where a variety of technical and economic challenges emerge. As the society’s reliance on electrical power continues to increase as a result of international decarbonisation commitments, the need for secure and uninterrupted delivery of electrical energy to all customers has never been greater. Power system protection plays an important enabling role in future decarbonized energy systems. This book includes ten papers covering a wide range of topics related to protection system problems and solutions, such as adaptive protection, protection of HVDC and LVDC systems, unconventional or enhanced protection methods, protection of superconducting transmission cables, and high voltage lightning protection.
Power-Aware Computer Systems ; Vol.3471 : 4th International Workshop, PACS 2004, Portland, OR, USA, December 5, 2004, Revised Selected Papers
Welcome to the proceedings of the Power-Aware Computer Systems (PACS 2004) workshop held in conjunction with the 37th Annual International Sym- sium on Microarchitecture (MICRO-37). The continued increase of power and energy dissipation in computer systems has resulted in higher cost, lower re- ability, and reduced battery life in portable systems. Consequently, power and energy have become ?rst-class constraints at all layers of modern computer s- tems. PACS 2004 is the fourth workshop in its series to explore techniques to reduce power and energy at all levels of computer systems and brings together academic and industry researchers. The papers in these proceedings span a wide spectrum of areas in pow- aware systems. We have grouped the papers into the following categories: (1) microarchitecture- and circuit-level techniques, (2) power-aware memory and interconnect systems, and (3) frequency- and voltage-scaling techniques. The ?rst paper in the microarchitecture group proposes banking and wri- back ?ltering to reduce register ?le power. The second paper in this group - timizes both delay and power of the issue queue by packing two instructions in each issue queue entry and by memorizing upper-order bits of the wake-up tag. The third paper proposes bit slicing the datapath to exploit narrow width operations, and the last paper proposes to migrate application threads from one core to another in a multi-core chip to address thermal problems.
Power-Aware Computer Systems ; 3rd International Workshop, PACS 2003, San Diego, CA, USA, December 1, 2003, Revised Papers
Welcome to the proceedings of the 3rd Power-Aware Computer Systems (PACS 2003) Workshop held in conjunction with the 36th Annual International Symposium on Microarchitecture (MICRO-36). The increase in power and - ergy dissipation in computer systems has begun to limit performance and has also resulted in higher cost and lower reliability. The increase also implies - duced battery life in portable systems. Because of the magnitude of the problem, all levels of computer systems, including circuits, architectures, and software, are being employed to address power and energy issues. PACS 2003 was the third workshop in its series to explore power- and energy-awareness at all levels of computer systems and brought together experts from academia and industry. These proceedings include 14 research papers, selected from 43 submissions, spanning a wide spectrum of areas inpower-aware systems.We have grouped the papers into the following categories: (1) compilers, (2) embedded systems, (3) microarchitectures, and (4) cache and memory systems. The ?rst paper on compiler techniques proposes pointer reuse analysis that is biased by runtime information (i.e., the targets of pointers are determined based on the likelihood of their occurrence at runtime) to map accesses to ener- e?cient memory access paths (e.g., avoid tag match). Another paper proposes compiling multiple programs together so that disk accesses across the programs can be synchronized to achieve longer sleep times in disks than if the programs are optimized separately.

Ocean Waves Breaking and Marine Aerosol Fluxes
This book presents a comprehensive study on the breaking of surface waves induced by wind and the relationship of breaking rate with marine aerosol fluxes. The book draws attention to the theoretical and experimental achievements in the study of wave breaking phenomena in deep water seas. In particular, it deals with the important problems of energy dissipation and the estimation of energy loss due to wave breaking in deep waters. The rationale behind existing methods and practical outcomes for the estimation of whitecap coverage of the sea surface and energy dissipation rate are given in detail.The book also focuses on the fundamentals of marine aerosols and their generation. The text provides a comprehensive overview of the currently available experimental data on marine aerosol fluxes and presents theoretical methodology of the estimation of the intensity of sea aerosol production. The systematic analysis leads to a novel approach in the development of links between aerosol production with sea state parameters and its seasonal variation in deep water seas.

This book provides reference for designers and researchers in hydraulic engineering, environment engineering and fluid mechanics.

Energy dissipation in molecular systems
Energy Dissipation in Molecular Systems analyzes experimental data on the redistribution and dissipation of energy injected into molecular systems by radiation or charged particles. These processes, competing with such practically important relaxation channels as chemical reaction or stimulated emission (laser action), are the primary focus in this monograph. Among other topics, the book treats vibrational redistribution and electronic relaxation in isolated molecules and the effects of inter-molecular interactions (collisions, complex formation, solvent effects) on the relaxation paths. Primary photo-chemical processes (such as isomerization, proton or hydrogen-atom transfer, electron transfer and ionization) are also treated as particular cases of vibrational or electronic relaxation. Only a basic knowledge of quantum mechanics and spectroscopy is assumed and calculations are kept to a strict minimum, making the book more accessible to students.
