Available in PDF, EPUB and Kindle. Book excerpt: UNMANNED AIRCRAF T SYSTEMS UNMANNED AIRCRAF T SYSTEMS An unmanned aircraft system (UAS), sometimes called a drone, is an aircraft without a human pilot on board ??? instead, the UAS can be controlled by an operator station on the ground or may be autonomous in operation. UAS are capable of addressing a broad range of applications in diverse, complex environments. Traditionally employed in mainly military applications, recent regulatory changes around the world are leading to an explosion of interest and wide-ranging new applications for UAS in civil airspace. Covering the design, development, operation, and mission profiles of unmanned aircraft systems, this single, comprehensive volume forms a complete, stand-alone reference on the topic. The volume integrates with the online Wiley Encyclopedia of Aerospace Engineering, providing many new and updated articles for existing subscribers to that work. The chapters cover the following items: Airframe configurations and design (launch systems, power generation, propulsion) Operations (missions, integration issues, and airspace access) Coordination (multivehicle cooperation and human oversight) With contributions from leading experts, this volume is intended to be a valuable addition, and a useful resource, for aerospace manufacturers and suppliers, governmental and industrial aerospace research establishments, airline and aviation industries, university engineering and science departments, and industry analysts, consultants, and researchers.

Book excerpt: Cet ouvrage s'adresse aux élèves d'écoles d'ingénieurs et aux étudiants suivant des formations universitaires de niveau similaire, mais aussi aux étudiants en BTS électrotechnique ou en IUT génie électrique. Il peut également intéresser les ingénieurs et techniciens utilisateurs de moteurs électriques. Cette nouvelle édition se propose de faire une synthèse des connaissances actuelles sur les moteurs électriques utilisés en conversion d'énergie. Il expose les principes de base et les lois physiques régissant leur fonctionnement, puis décrit en détail les différents types de moteurs existants, suivant leur degré d'utilisation actuel : le moteur asynchrone, le plus répandu de tous ; le moteur synchrone, dans ses deux versions : bobinée pour les fortes puissances et à aimant pour les entraînements à hautes performances ; le moteur à réluctance variable, dispositif prometteur et encore en développement ; le moteur à courant continu, obsolète pour les applications nouvelles, mais toujours présent dans les systèmes déjà installés.

Download or read book Touching for Knowing written by Yvette Hatwell and published by John Benjamins Publishing. This book was released on 2003-01-01 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dominance of vision is so strong in sighted people that touch is sometimes considered as a minor perceptual modality. However, touch is a powerful tool which contributes significantly to our knowledge of space and objects. Its intensive use by blind persons allows them to reach the same levels of knowledge and cognition as their sighted peers.In this book, specialized researchers present the recent state of knowledge about the cognitive functioning of touch. After an analysis of the neurophysiology and neuropsychology of touch, exploratory manual behaviors, intramodal haptic (tactual-kinesthetic) abilities and cross-modal visual-tactual coordination are examined in infants, children and adults, and in non-human primates. These studies concern both sighted and blind persons in order to know whether early visual deprivation modifies the modes of processing space and objects. The last section is devoted to the technical devices favoring the school and social integration of the young blind: Braille reading, use of raised maps and drawings, sensory substitution displays, and new technologies of communication adapted for the blind.

Available in PDF, EPUB and Kindle. Book excerpt: 'This work will be of immense value to those who are undertaking a significant post-graduate research study in Education. The array of impressive contributors writes in an accessible and clear manner, and brings the attention of the reader to both technical and conceptual terms. This book certainly will be an addition to my own reference library' - Susan Groundwater-Smith, Faculty of Education and Social Work, University of Sydney This straightforward and jargon-free book will provide students with the theoretical understandings, practical knowledge and skills they need to carry out independent research. The international contributors identify key research methodologies, data collection tools and analysis methods, and focus on the direct comparisons between them. Each chapter sets out the strengths and weaknesses of a key research method by: identifying specific research designs presenting a series of relevant data collection tools highlighting which analytical methods which can be used. The chapters cover the full range of methods and methodologies, including internet research, mixed methods research and the various modes of ethnographic research. Additional online materials are also available including links to useful journal articles enabling further reading and exploration of each chapter.

Download or read book Language Culture and Community in Teacher Education written by Maria Estela Brisk and published by Routledge. This book was released on 2013-09-13 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published by Routledge for the American Association of Colleges for Teacher Education This volume addresses the pressing reality in teacher education that all teachers need to be prepared to work effectively with linguistically and culturally diverse student populations. Every classroom in the country is already, or will soon be, deeply affected by the changing demographics of America’s students. Marilyn Cochran-Smith’s Foreword and Donaldo Macedo’s Introductory Essay set the context with respect to teacher education and student demographics, followed by a series of chapters presented in three sections: knowledge, practice, and policy. The literature on language education has typically been discussed in relation to preparing ESL or bilingual teachers. Typically, needs of culturally and linguistically diverse students, including immigrants, refugees, language minority populations, African Americans, and deaf students, have been addressed separately. This volume emphasizes that these children have both common educational needs and needs that are culturally and linguistically specific. It is directed to the preparation of ALL teachers who work with culturally and linguistically diverse students. It not only focuses on how teachers need to change but how faculty and curriculum need to be transformed, and how to better train teacher education candidates to understand and work efficaciously with the communities in which culturally and linguistically diverse students tend to be predominant. The American Association of Colleges for Teacher Education (AACTE) is a national, voluntary association of higher education institutions and related organizations. Our mission is to promote the learning of all PK-12 students through high-quality, evidence-based preparation and continuing education for all school personnel.
