  • Connu pour être un des grands polémistes du XVIIIe siècle et héritier du libertinage érudit, le marquis Boyer d'Argens (1704-1771) l'est moins en revanche pour ses Lettres chinoises. À l'époque, les Lettres persanes de Montesquieu ont imposé un procédé littéraire cher aux philosophes des Lumières, qui consiste, selon Roger Caillois, à se feindre étranger à la société où l'on vit " pour mieux la critiquer. Montesquieu conte ainsi les surprises de deux Persans visitant l'Europe, spécialement la France. Ici, l'on présente un choix des Lettres chinoises du marquis d'Argens, analogues par plus d'un trait à cette démarche. Avec une différence notable cependant, à savoir que l'auteur met en valeur la civilisation même de ses voyageurs, Chinois, en s'appuyant sur l'information diffusée en Europe par les jésuites alors établis en Chine. On ne peut donc manquer de se demander : quelle est la Chine des Lettres chinoises ? Et quelle est l'authenticité de cette Chine ? Cette ouverture à une autre culture mérite en tous cas le détour.".

  • Through a harrowing first-person account of an eruption and its aftermath, SURVIVING GALERAS reveals the fascinating, high-risk realm of volcanology and explores the profound impact volcanoes have had on the earth's landscapes and civilizations.
    In 1993, Stanley Williams, an eminent volcanologist, was standing on top of a Colombian volcano called Galeras when it erupted, killing six of his colleagues instantly. As Williams tried to escape the blast, he was pelted with white-hot projectiles traveling faster than bullets. Within seconds he was cut down, his skull fractured, his right leg almost severed, his backpack aflame. Williams lay helpless and near death on Galeras's flank until two brave women -- friends and fellow volcanologists -- mounted an astonishing rescue effort to carry him safely off the mountain.
    The tale of how Williams survived Galeras is the framework for a groundbreaking book about volcanoes, their physical and cultural impact, and the tiny cadre of scientists who risk their own lives to gain knowledge that might one day save many others' lives.
    Volcanoes unleash supremely powerful, unpredictable forces, and we have paid dearly for our understanding of their behavior. Even with ever more sensitive measuring tools and protective equipment, at least one volcanologist, on average, dies each year. Yet Williams and his fellow scientist-adventurers continue to unveil the enigmatic and miraculous workings of volcanoes and to piece together methods for predicting their actions. Volcanologists often put themselves in peril, not only because the discipline attracts risk-takers but because they know that volcanoes threaten as many as 500 million people worldwide. For Seattle, Tokyo, Mexico City, Naples -- and for volcanologists -- the clock is ticking.

  • « Oui, nous avons compté douze morts - comme par hasard, de cancer et d'amiante - depuis que l'usine est fermée. Ce nombre incalculable d'hommes et de femmes qui ont travaillé à Amisol pendant ses soixante-cinq ans d'existence et qui, aujourd'hui, dans la région clermontoise, toussent, souffrent et meurent de l'usine du 35, rue du Pré-de-la-Reine, à Clermont-Ferrand. Lorsque, le 13 décembre 1974, l'assemblée générale des travailleurs décida de ratifier la proposition du syndicat CGT d'occuper l'usine, qui aurait pu penser qu'une page aussi noire de l'histoire de la classe ouvrière commençait à s'écrire ? » (extrait de l'avant-propos).

  • This book presents detailed descriptions of chaos for continuous-time systems. It is the first-ever book to consider chaos as an input for differential and hybrid equations. Chaotic sets and chaotic functions are used as inputs for systems with attractors: equilibrium points, cycles and tori. The findings strongly suggest that chaos theory can proceed from the theory of differential equations to a higher level than previously thought. The approach selected is conducive to the in-depth analysis of different types of chaos. The appearance of deterministic chaos in neural networks, economics and mechanical systems is discussed theoretically and supported by simulations. As such, the book offers a valuable resource for mathematicians, physicists, engineers and economists studying nonlinear chaotic dynamics.

  • This SpringerBrief investigates and reviews the development and various applications of mobile crowd sensing (MCS). With the miniaturization of sensors and the popularity of smart mobile devices, MCS becomes a promising solution to efficiently collect different types of information, such as traffic conditions, air quality, temperature and more, which is covered in this brief. The features, novelty, and applications of MCS are elaborated in detail in this brief. In addition, the basic knowledge about auction theory and incentive mechanism design is introduced.Incentive mechanism design plays a key role in the success of MCS. With an efficient incentive mechanism, it is possible to attract enough mobile users to participate in a MCS system, thus enough high quality sensing data can be collected. Two types of incentive mechanisms with different system models are introduced in this brief. One is the reputation-aware incentive mechanism, and another is the social-aware incentive mechanism.This SpringerBrief  covers the significance and the impacts of both reputation and social relationship of smartphone users (SUs) in MCS and presents extensive simulation results to demonstrate the good performance of the proposed incentive mechanisms compared with some existing counterparts.The target audience for this SpringerBrief is researchers and engineers in the area of wireless communication and networking, especially those who are interested in the mobile crowd sensing or incentive mechanism design. Meanwhile, it is also intended as a reference guide for advanced level students in the area of wireless communications and computer networks.

  • The aim of this book is to provide a comprehensive overview of the most important movement disorders and describe the rehabilitation tools available for each disease. The management of movement disorders is challenging since most of these diseases are not curable and hardly treatable. Many of the disorders are chronic or degenerative diseases, therefore patients develop motor complications that could improve with rehabilitation interventions.  Movement Disorders Rehabilitation intends to serve as a practical guide on the field, attracting the interest of professionals and researchers on the fields of neurology, physical therapy, occupational therapy, speech therapy and other correlated therapies.

  • This thesis describes the controlled immobilization of molecules between two cuboidal metal nanoparticles by means of a self-assembly method to control the quantum plasmon resonances. It demonstrates that quantum-plasmonics is possible at length scales that are useful for real applications. Light can interact with certain metals and can be captured in the form of plasmons, which are collective, ultra-fast oscillations of electrons that can be manipulated at the nano-scale. Surface plasmons are considered as a promising phenomenon for potentially bridging the gap between fast-operating-speed optics and nano-scale electronics. Quantum tunneling has been predicted to occur across two closely separated plasmonic resonators at length scales (<0.3 nm) that are not accessible using present-day nanofabrication techniques.

    Unlike top-down nanofabrication, the molecules between the closely-spaced metal nanoparticles could control the gap sizes down to sub-nanometer scales and act as the frequency controllers in the terahertz regime, providing a new control parameter in the fabrication of electrical circuits facilitated by quantum plasmon tunneling.

  • This book offers various perspectives on the complex and crosscutting concepts of the science, technology, engineering, and mathematics (STEM) disciplines in the classroom context.  Presenting empirical studies, it reveals how researchers in the Asia-Pacific Region planned and implemented STEM education in the classroom. Further, it discusses the assessment of STEM learning to clarify what important elements should be included and how researchers and educators frame and design assessment tools. The book consists of four parts: potential and trends in STEM education; teachers' practical knowledge for STEM teaching; STEM teaching practices; and assessment of STEM learning. Providing evidence on developing curriculums, implementing instructional practices and educating classroom teachers, it is intended for readers wanting to explore STEM education from multiple perspectives.

  • The book is concerned with the concepts of chaos and fractals, which are within the scopes of dynamical systems, geometry, measure theory, topology, and numerical analysis during the last several decades. It is revealed that a special kind of Poisson stable point, which we call an unpredictable point, gives rise to the existence of chaos in the quasi-minimal set. This is the first time in the literature that the description of chaos is initiated from a single motion. Chaos is now placed on the line of oscillations, and therefore, it is a subject of study in the framework of the theories of dynamical systems and differential equations, as in this book. The techniques introduced in the book make it possible to develop continuous and discrete dynamics which admit fractals as points of trajectories as well as orbits themselves. To provide strong arguments for the genericity of chaos in the real and abstract universe, the concept of abstract similarity is suggested.
