Energy-Efficient Driving of Road Vehicles: Toward Cooperative, Connected, and Automated Mobility (Lecture Notes in Intelligent Transportation and Infrastructure)
by Antonio Sciarretta Ardalan VahidiThis book elaborates the science and engineering basis for energy-efficient driving in conventional and autonomous cars. After covering the physics of energy-efficient motion in conventional, hybrid, and electric powertrains, the book chiefly focuses on the energy-saving potential of connected and automated vehicles. It reveals how being connected to other vehicles and the infrastructure enables the anticipation of upcoming driving-relevant factors, e.g. hills, curves, slow traffic, state of traffic signals, and movements of nearby vehicles. In turn, automation allows vehicles to adjust their motion more precisely in anticipation of upcoming events, and to save energy. Lastly, the energy-efficient motion of connected and automated vehicles could have a harmonizing effect on mixed traffic, leading to additional energy savings for neighboring vehicles. Building on classical methods of powertrain modeling, optimization, and optimal control, the book further develops the theory of energy-efficient driving. In addition, it presents numerous theoretical and applied case studies that highlight the real-world implications of the theory developed. The book is chiefly intended for undergraduate and graduate engineering students and industry practitioners with a background in mechanical, electrical, or automotive engineering, computer science or robotics.

Energy-Efficient Modular Exponential Techniques for Public-Key Cryptography: Efficient Modular Exponential Techniques
by Satyanarayana Vollala N. Ramasubramanian Utkarsh TiwariCryptographic applications, such as RSA algorithm, ElGamal cryptography, elliptic curve cryptography, Rabin cryptosystem, Diffie -Hellmann key exchange algorithm, and the Digital Signature Standard, use modular exponentiation extensively. The performance of all these applications strongly depends on the efficient implementation of modular exponentiation and modular multiplication. Since 1984, when Montgomery first introduced a method to evaluate modular multiplications, many algorithmic modifications have been done for improving the efficiency of modular multiplication, but very less work has been done on the modular exponentiation to improve the efficiency. This research monograph addresses the question- how can the performance of modular exponentiation, which is the crucial operation of many public-key cryptographic techniques, be improved? <P><P> The book focuses on Energy Efficient Modular Exponentiations for Cryptographic hardware. Spread across five chapters, this well-researched text focuses in detail on the Bit Forwarding Techniques and the corresponding hardware realizations. Readers will also discover advanced performance improvement techniques based on high radix multiplication and Cryptographic hardware based on multi-core architectures.

Energy Efficient Spectrum Resources Usage in WPANs: IEEE 82.15.4 MAC Sub-layer Protocols (River Publishers Series in Communications and Networking)
by Luís Miguel Borges Norberto Barroca Periklis Chatzimisios Fernando José VelezWireless Sensor Networks (WSNs) and the Internet of Things are facing tremendous advances both in terms of energy-efficiency as well as in the number of available applications. Consequently, there are challenges that need to be tackled for the future generation of WSNs. After giving an overview of the WSN protocols and IEEE 802.15.4 standard, this book proposes IEEE 802.15.4 Medium Access Control (MAC) sub-layer performance enhancements by employing not only RTS/CTS combined with packet concatenation but also scheduled channel poling (MC-SCP). Results have shown that the use of the RTS/CTS mechanism improves channel efficiency by decreasing the deferral time before transmitting a data packet. Furthermore, the Sensor Block Acknowledgment MAC (SBACK-MAC) protocol enables more efficiency as it allows the aggregation of several acknowledgement responses in one special Block Acknowledgment (BACK) Response packet. The throughput and delay performance have been mathematically derived under both ideal conditions (a channel environment with no transmission errors) and non-ideal conditions (with transmission errors). Simulation results successfully validate the proposed analytical models. This research reveals the importance of an appropriate design for the MAC sub-layer protocol for the desired WSN application. Depending on the mission of the WSN application, different protocols are required. Therefore, the overall performance of a WSN application certainly depends on the development and application of suitable e.g., MAC, network layer protocols.

by Philip MoserThis dissertation provides the first systematic analysis of the dynamic energy efficiency of vertical-cavity surface-emitting lasers (VCSELs) for optical interconnects, a key technology to address the pressing ecological and economic issues of the exponentially growing energy consumption in data centers. Energy-efficient data communication is one of the most important elds in "Green Photonics" enabling higher bit rates at signicantly reduced energy consumption per bit. In this thesis the static and dynamic properties of GaAs-based oxide-confined VCSELs emitting at 850 nm and 980 nm are analyzed and general rules for achieving energy-efficient data transmission using VCSELs at any wavelength are derived. These rules are verified in data transmission experiments leading to record energy-efficient data transmission across a wide range of multimode optical fiber distances and at high temperatures up to 85°C. Important trade-offs between energy efficiency, temperature stability, modulation bandwidth, low current-density operation and other VCSEL properties are revealed and discussed.

Energy, Environment, Natural Resources and Business Competitiveness: The Fragility of Interdependence
by Dimitris N. ChorafasEvery generation leaves both assets and liabilities to the next. Alert people can see we are going to leave our children and grandchildren with a nearly unsolvable test of energy supplies; waste polluting the air and water; and the appalling problem of a huge and uncontrollable explosion in world population. Energy, Environment, Natural Resources and Business Competitiveness addresses itself to those having a professional, academic or general interest in these issues: - Energy sources, their nature and contribution, - Environmental problems associated to power production and usage, - Financing and control of energy-related projects and processes, - Future direction of agriculture produce now used as energy, - Complex social and technical issues resulting from lack of family planning - and, therefore, of demands for energy, - Impact of energy and an exploding population on pollution, - Truth and hype about the most talked about environmental subjects. In this fourth book for Gower, Dimitris Chorafas reviews Europe, America and Asia's energy needs in the coming decade, pointing out that current policies are inadequate at best, and more likely disastrous for the economy. Governments persist in having their own agenda and priorities as well as plenty of constraints and taboos, yet when he critically examines the challenges Dr Chorafas concludes that no government can solve all current energy problems by acting alone. The book confronts current thinking, and its after-effect on policies and practices. Readers accustomed to mainstream books and articles which blame fossil fuels for a deteriorating world environment will find this a contrary opinion.

Energy Fables: Challenging Ideas in the Energy Sector
by Jenny Rinkinen Elizabeth Shove Jacopo TorritiEnergy Fables: Challenging Ideas in the Energy Sector takes a fresh look at key terms and concepts around which energy research and policy are organised. Drawing on recent research in energy and transport studies, and combining this with concepts from sociology, economics, social theory and technology studies, the chapters in this collection review and challenge different aspects of received wisdom. Brief but critical introductions to classic notions like those of ‘energy efficiency’, ‘elasticity’, ‘energy services’ and the ‘energy trilemma’, together with discussions and analyses of well-worn phrases about ‘low hanging fruit’ and ‘keeping the lights on’, articulate aspects of the energy debate that are often taken for granted. In re-working these established themes and adding twists to familiar tales, the authors develop a repertoire of new ideas about the fundamentals of energy demand and carbon reduction. This book presents a valuable and thought-provoking resource for students, researchers and policy-makers interested in energy demand, politics and policy.
