Energy Autonomy of Batteryless and Wireless Embedded Systems covers the numerous new applications of embedded systems that are envisioned in the context of aeronautics, such as sensor deployment for flight tests or for structural health monitoring. However, the increasing burden of on-board cabling requires wireless solutions. Moreover, concerns such as safety or system lifetime preclude the use of electrochemical energy storage. Ambient energy capture, storage and management are therefore key topics. This book presents these concepts and illustrates them through actual implementations in airliners. With five years of experience within this specialist field, the authors present results from actual flight tests via a partnership with Airbus. Basic concepts are summarized, together with practical implementations in airliners, enriching the book through the very specific aspects related to embedded systems deployed in aircraft. This book will appeal to both students and practising engineers in the field. Features a complete study of the energy management architecture, from general concepts to specific applications Presents results from thorough studies on electrostatic energy storage Provides hands-on consideration of industrial implementations in airliners, specifically in harsh environments Includes actual results obtained from flight tests

4 zettabytes (4 billion terabytes) of data generated in 2013, 44 zettabytes predicted for 2020 and 185 zettabytes for 2025. These figures are staggering and perfectly illustrate this new era of data deluge. Data has become a major economic and social challenge. The speed of processing of these data is the weakest link in a computer system: the storage system. It is therefore crucial to optimize this operation. During the last decade, storage systems have experienced a major revolution: the advent of flash memory. Flash Memory Integration: Performance and Energy Issues contributes to a better understanding of these revolutions. The authors offer us an insight into the integration of flash memory in computer systems, their behavior in performance and in power consumption compared to traditional storage systems. The book also presents, in their entirety, various methods for measuring the performance and energy consumption of storage systems for embedded as well as desktop/server computer systems. We are invited on a journey to the memories of the future. Ideal for computer scientists, featuring low level details to concentrate on system issues Tackles flash memory aspects while spanning domains such as embedded systems and HPC Contains an exhaustive set of experimental results conducted in the Lab-STICC laboratory Provides details on methodologies to perform performance and energy measurements on flash storage systems

Failures caused by electrostatic discharges (ESD) constitute a major problem concerning the reliability and robustness of integrated circuits and electronic systems. This book summarizes the many diverse methodologies aimed at ESD protection and shows, through a number of concrete studies, that the best approach in terms of robustness and cost-effectiveness consists of implementing a global strategy of ESD protection. ESD Protection Methodologies begins by exploring the various normalized test techniques that are used to qualify ESD robustness as well as characterization and defect localization methods aimed at implementing corrective measures. Due to the increasing complexity of integrated circuits, it is important to be able to provide a simulation in which the implemented ESD protection strategy provides the desired protection, while not harming the performance levels of the circuit. Therefore, the main features and difficulties related to the different types of simulation, finite element, SPICE-type and behavioral, are then studied. To conclude, several case studies are presented which provide real-life examples of the approaches explained in the previous chapters and validate a number of the strategies from component to system level. Provides a global ESD protection approach from component to system, including both the proposal of investigation techniques and predictive simulation methodologies Addresses circuit and system designers as well as failure analysis engineers Provides the description of specifically developed investigation techniques and the application of the proposed methodologies to real case studies

This book describes an effective approach to the cooperative and coordinated control of multivehicle systems. This rigorous analytic approach guarantees the stability of coordinated and cooperating vehicles using distributed protocols and uses low-energy, event-triggered mechanisms for networked vehicle control. The text covers: design of a cooperative protocol to achieve consensus for multivehicle systems, allowing cooperation that is resistant to the effects of packet loss and/or adversarial attack; analysis and synthesis of an event-triggering mechanism for cooperative multivehicle systems over uncertain networks; and the problem of distributed leader-following consensus and methods for compelling multivehicle systems to reach consensus. Throughout the book, cooperation problems are transformed into stability problems. Lyapunov theory is used to guarantee cooperation among agents. The distributed approach is applied to triggering mechanisms, the cooperation process, and the impact of cyber-attacks. Discrete-time analysis shows how the event-based structure can be designed to match the performance of continuous-time counterparts. The book details applications and computer simulation with several practical examples. This book is of interest to a wide audience from the graduate student, through the academic researcher to the industrial practitioner, all of them sharing a common interest in the stability and security of multiagent systems.
