Book excerpt: Les réseaux de capteurs sans-fil sont une nouvelle technologie qui permet de déployer des capteurs hétérogènes et de les faire communiquer sans fil et de façon autonome. Cette capacité nouvelle à surveiller ou instrumenter le monde qui nous entoure ouvre la voie à de nouvelles applications innovantes ou à une évolution majeure d'applications déjà existantes.D'une dizaine de nœuds à plusieurs milliers, les réseaux de capteurs sans fil commencent à conquérir le monde industriel et notre vie quotidienne. Leurs besoins en communications, gestion, génération et stockage de l'énergie, miniaturisation et réduction des coûts ne nécessitent pas seulement de perfectionner les technologies actuelles mais bien d'en inventer de nouvelles. Parmi toutes les applications révolutionnaires des réseaux de capteurs sans fil comme dans la santé, l'environnement, l'industrie et le militaire, l'une des applications les plus transformatrices est la surveillance de structure. La surveillance de structure est l'art de surveiller tout ce qui peut s'abimer, s'user ou tomber en panne. Elle est particulièrement importante dans les domaines des transports et du bâtiment, étant donné que la sécurité des personnes est en jeu. En plaçant aux endroits stratégiques des capteurs sans-fil, il sera possible de prévoir et de prévenir la défaillance d'un pont, l'usure d'un avion ou d'un train ou la déformation d'un bâtiment. La surveillance de structure permet de prévenir les pannes et les défaillances, de réduire les coûts de maintenance et d'améliorer les performances. C'est un processus complexe qui implique plusieurs technologies : des capteurs, la transmission de l'information et l'analyse des données. La nature (accéléromètre, gyroscope, jauge de contrainte, température, pression, fuite, givre, etc. . .), la position ainsi que le nombre de capteurs sont dictés et dépendants des besoins de l'analyse de la structure qui doit être effectuée. De ce fait, les contraintes imposées au système de transmission de données sans fil, afin d'offrir une couverture suffisante de la structure de l'appareil avec plusieurs centaines voire plusieurs milliers de capteurs que leur localisation rendra difficile d'accès, nécessitent des nouvelles innovations en matière d'efficacité énergétique et de performance de communication. Ce travail s'intéresse à la conception et l'implémentation d'un système de transmission de données dans un réseau de capteurs sans-fil. Après une présentation des exigences du système de surveillance de structure aéronautique, l'architecture générale du système de surveillance est décrite. Une couche physique spécifique à haute efficacité énergétique basée sur l'Impulse-Radio UltraWide Band a été conçue. Les designs complets de l'émetteur et du récepteur IR-UWB sont présentés ainsi que l'optimisation du codage canal par rapport à la consommation énergétique. Une couche MAC spécifique permettant un nombre important de nœuds et une efficacité énergétique élevée basée sur du TDMA reconfigurable a été conçue. Plusieurs prototypes ont été implémentés pour valider la conception et démontrer les performances. Ces implémentation utilise des techniques avancées d'optimisation de la consommation énergétique et de reconfigurabilité afin de répondre aux exigences des réseaux de capteurs sans-fil. Des simulations ASIC permettent également de prévoir que ce système permettra de supporter des débits applicatifs de plusieurs centaines de mégabits par seconde, tout en permettant à plusieurs dizaines de nœuds de communiquer. Les performances énergétiques de ce système de communication sont aujourd'hui à l'état de l'art. Enfin, cette technologie de communication sans-fil a été intégrée dans un système complet de deux nœuds capteurs et d'un routeur dans un démonstrateur FPGA.

Book excerpt: Late in 2017, the global significance of the conversation about artificial intelligence (AI) changed forever. China put the world on alert when it released a plan to dominate all aspects of AI across the planet. Only weeks later, Vladimir Putin raised a Russian red flag in response by declaring AI the future for all humankind, and proclaiming that, "Whoever becomes the leader in this sphere will become the ruler of the world." The race was on. Consistent with their unique national agendas, countries throughout the world began plotting their paths and hurrying their pace. Now, not long after, the race has become a sprint. Despite everything at stake, to most of us AI remains shrouded by a cloud of mystery and misunderstanding. Hidden behind complicated and technical jargon and confused by fantastical depictions of science fiction, the modern realities of AI and its profound implications are hard to decipher, but crucial to recognize. In T-Minus AI: Humanity's Countdown to Artificial Intelligence and the New Pursuit of Global Power, author Michael Kanaan explains AI from a human-oriented perspective we can all finally understand. A recognized national expert and the U.S. Air Force's first Chairperson for Artificial Intelligence, Kanaan weaves a compelling new view on our history of innovation and technology to masterfully explain what each of us should know about modern computing, AI, and machine learning. Kanaan also dives into the global implications of AI by illuminating the cultural and national vulnerabilities already exposed and the pressing issues now squarely on the table. AI has already become China's all-purpose tool to impose its authoritarian influence around the world. Russia, playing catch up, is weaponizing AI through its military systems and now infamous, aggressive efforts to disrupt democracy by whatever disinformation means possible. America and like-minded nations are awakening to these new realities—and the paths they're electing to follow echo loudly the political foundations and, in most cases, the moral imperatives upon which they were formed. As we march toward a future far different than ever imagined, T-Minus AI is fascinating and crucially well-timed. It leaves the fiction behind, paints the alarming implications of AI for what they actually are, and calls for unified action to protect fundamental human rights and dignities for all.

Book excerpt: The Cambridge Handbook of Engineering Education Research is the critical reference source for the growing field of engineering education research, featuring the work of world luminaries writing to define and inform this emerging field. The Handbook draws extensively on contemporary research in the learning sciences, examining how technology affects learners and learning environments, and the role of social context in learning. Since a landmark issue of the Journal of Engineering Education (2005), in which senior scholars argued for a stronger theoretical and empirically driven agenda, engineering education has quickly emerged as a research-driven field increasing in both theoretical and empirical work drawing on many social science disciplines, disciplinary engineering knowledge, and computing. The Handbook is based on the research agenda from a series of interdisciplinary colloquia funded by the US National Science Foundation and published in the Journal of Engineering Education in October 2006.

Book excerpt: International Conference on Artificial Intelligence in Renewable Energetic Systems, IC-AIRES2019, 26-28 November 2019, Taghit-Bechar, Algeria. The challenges of the energy transition in the medium term lead to numerous technological breakthroughs in the areas of production, optimal distribution and the rational use of energy and renewable energy (energy efficiency and optimization of consumption, massive electrification, monitoring and control energy systems, cogeneration and energy recovery processes, new and renewable energies, etc.). The fall in the cost of renewable energies and the desire for a local control of energy production are today calling for a profound change in the electricity system. Local authorities are at the center of energy developments by taking into account the local nature of certain energy systems, heat networks, geothermal energy, waste heat recovery, and electricity generation from household waste. On the other side, digital sciences are at the heart of connected objects and intelligent products that combine information processing and communication capabilities with their environment. Digital technology is at the center of new systems engineering approaches (3D modeling, virtualization, simulation, digital prototyping, etc.) for the design and development of intelligent systems. The book deals with various topics ranging from the design, development and maintenance of energy production systems, transport, distribution or storage of energy, optimization of energy efficiency, especially in the use of energy. innovation in the fields of energy production from renewable energies, management of energy networks: electricity, fluids, gas, district heating, energy storage modes: battery, super-capacitors , overseeing energy supply through supervision, control and diagnosis, risk management, as well as the design and management of smart grids: microgrid, smartgrid. This imposes the model of energy empowerment in the advent of smart cities. Empower the world’s most vulnerable energy-poor citizens and establish growing and vibrant socioeconomic communities, by academics, students in engineering and data computing from around the world who have chosen an academic path leading to an electric power and energy engineering and artificial intelligence to advancing technology for the advantage of humanity.

Available in PDF, EPUB and Kindle. Book excerpt: This book features cutting-edge research presented at the second international conference on Artificial Intelligence in Renewable Energetic Systems, IC-AIRES2018, held on 24–26 November 2018, at the High School of Commerce, ESC-Koléa in Tipaza, Algeria. Today, the fundamental challenge of integrating renewable energies into the design of smart cities is more relevant than ever. While based on the advent of big data and the use of information and communication technologies, smart cities must now respond to cross-cutting issues involving urban development, energy and environmental constraints; further, these cities must also explore how they can integrate more sustainable energies. Sustainable energies are a major determinant of smart cities’ longevity. From an environmental and technological standpoint, these energies offer an optimal power supply to the electric network while creating significantly less pollution. This requires flexibility, i.e., the availability of supply and demand. The end goal of any smart city is to improve the quality of life for all citizens (both in the city and in the countryside) in a way that is sustainable and respectful of the environment. This book encourages the reader to engage in the preservation of our environment, every moment, every day, so as to help build a clean and healthy future, and to think of the future generations who will one day inherit our planet. Further, it equips those whose work involves energy systems and those engaged in modelling artificial intelligence to combine their expertise for the benefit of the scientific community and humanity as a whole.
