This book was released on 2011 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: Le domaine de l'instrumentation des capteurs est en constante évolution. Ce travail propose la conception des éléments clefs qui constituent les chaines d'instrumentations de capteurs d'aujourd'hui au travers de 3 applications concrètes. La première application est la mesure de vitesse et de position, par exemple dans un roulement. Nous présentons la conception et la réalisation d'un circuit analogique pour le conditionnement d'un capteur de type magnétorésistif. Ce capteur mesure le champ magnétique généré par les pôles magnétiques d'une roue codeuse. Le circuit est optimisé en bruit, en consommation et travaille sur une bande passante de plusieurs kHz. Pour compenser la dispersion des capteurs, le circuit permet des réglages d'offset et une calibration de gains. Il contient également une mémoire de type OTP (One Time Programmable Memory) qui sauvegarde les réglages associés au capteur. La deuxième application est la mesure de signaux de type EcoG afin d'interfacer le cerveau humain. Nous décrivons la conception et la réalisation d'un convertisseur Analogique/Numérique de type SAR. Il possède un convertisseur numérique analogique capacitif avec une capacité d'atténuation afin de réduire le nombre total de condensateur et ainsi la consommation. Le comparateur possède une entrée rail-to-rail et un système de préamplification avec auto zéro pour diminuer l'offset. Sa consommation est de 86μW pour une vitesse de 24Ks/S et 12bits de résolution. Enfin la troisième application est la mesure de pression stationnaire sur la voilure des avions afin d'en connaître les contraintes. Nous décrivons l'étude architecturale d'un convertisseur sigma-delta permettant d'atteindre une grande résolution pour des signaux de faible fréquence. Il sera de type incrémentale et répondra à des applications de type instrumentation de capteur. Sa résolution est de 16bits ENOB pour une fréquence maximale d'entrée de 100Hz et minimale de sortie d'1Ks/S. Le mode incrémental permettra d'obtenir une sortie en réponse à une requête de manière asynchrone. Une modélisation de chaque élément du système complet convertisseur plus capteur a été effectuée sous Matlab. L'étude de la partie filtrage numérique du convertisseur et l'optimisation de son implémentation numérique sont présentées. Cette étude architecturale complète aboutit au dimensionnement de chaque élément pour répondre au cahier des charges de l'application .
Book Synopsis Intuition in Science and Mathematics by : Efraim Fischbein
Download or read book Intuition in Science and Mathematics written by Efraim Fischbein and published by Springer Science & Business Media. This book was released on 2005-12-19 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: In writing the present book I have had in mind the following objectives: - To propose a theoretical, comprehensive view of the domain of intuition. - To identify and organize the experimental findings related to intuition scattered in a wide variety of research contexts. - To reveal the educational implications of the idea, developed for science and mathematics education. Most of the existing monographs in the field of intuition are mainly concerned with theoretical debates - definitions, philosophical attitudes, historical considerations. (See, especially the works of Wild (1938), of Bunge (1 962) and of Noddings and Shore (1 984).) A notable exception is the book by Westcott (1968), which combines theoretical analyses with the author’s own experimental studies. But, so far, no attempt has been made to identify systematically those findings, spread throughout the research literature, which could contribute to the deciphering of the mechanisms of intuition. Very often the relevant studies do not refer explicitly to intuition. Even when this term is used it occurs, usually, as a self-evident, common sense term.

Book Synopsis Agents of Repression by : Ward Churchill
Download or read book Agents of Repression written by Ward Churchill and published by South End Press. This book was released on 2002 with total page 550 pages. Available in PDF, EPUB and Kindle. Book excerpt: For those wondering how Bill Clinton could pardon white-collar fugitive Marc Rich but not Native American leader Leonard Peltier, important clues can be found in this classic study of the FBI's COINTELPRO (Counterintelligence Program). Agents of Repression includes an incisive historical account of the FBI siege of Wounded Knee, and reveals the viciousness of COINTELPRO campaigns targeting the Black Liberation movement. The authors' new introduction examines the legacies of the Panthers and AIM, and shows how the FBI still presents a threat to those committed to fundamental social change. Ward Churchill is author of From a Native Son. Jim Vander Wall is co-author of The COINTELPRO Papers: Documents from the FBI's Secret Wars Against Dissent in the United States, with Ward Churchill.
Download or read book Developing Teachers written by Chris Day and published by Routledge. This book was released on 2002-01-04 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Effective schools or improving schools are fashionable terms in the rhetoric of recent education movements, yet the heart of these movements is often more to do with teaching quality than with school practice. This book takes a holistic view of teacher development, examining the contexts and conditions of teaching: school leadership and culture; teachers' lives and histories; change; teacher learning, competence and expertise; and the moral purposes of teaching. Day looks at the conditions under which teacher development may be enhanced, and brings together research and other information, from the UK and overseas.

This book was released on 2001-11-30 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interest in computer applications has led to a new attitude to applied logic in which researchers tailor a logic in the same way they define a computer language. In response to this attitude, this text for undergraduate and graduate students discusses major algorithmic methodologies, and tableaux and resolution methods. The authors focus on first-order logic, the use of proof theory, and the computer application of automated searches for proofs of mathematical propositions.

Book Synopsis The Black Panther Party by : The Dr. Huey P. Newton Foundation
Download or read book The Black Panther Party written by The Dr. Huey P. Newton Foundation and published by UNM Press. This book was released on 2010-03-28 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Black Panther Party represents Black Panther Party members' coordinated responses over the last four decades to the failure of city, state, and federal bureaucrats to address the basic needs of their respective communities. The Party pioneered free social service programs that are now in the mainstream of American life. The Party's Sickle Cell Anemia Research Foundation, operated with Oakland's Children's Hospital, was among the nation's first such testing programs. Its Free Breakfast Program served as a model for national programs. Other initiatives included free clinics, grocery giveaways, school and education programs, senior programs, and legal aid programs. Published here for the first time in book form, The Black Panther Party makes the case that the programs' methods are viable models for addressing the persistent, basic social injustices and economic problems of today's American cities and suburbs.
Book Synopsis The Archaeology of Etruscan Society by : Vedia Izzet
Download or read book The Archaeology of Etruscan Society written by Vedia Izzet and published by Cambridge University Press. This book was released on 2007-12-13 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: The late sixth century was a period of considerable change in Etruria; this change is traditionally seen as the adoption of superior models from Greece. In a re-alignment of agency, this book examines a wide range of Etruscan material culture - mirrors, tombs, sanctuaries, houses and cities - in order to demonstrate the importance of local concerns in the formation of Etruscan material culture. Drawing on theoretical developments, the book emphasises the deliberate nature of the smallest of changes in material culture form, and develops the concept of surface as a unifying key to understanding the changes in the ways Etruscans represented themselves in life and death. This concept allows a uniquely holistic approach to the archaeology of Etruscan society and has the potential for other archaeological investigations. The book will interest all scholars and students of classical archaeology.

Book Synopsis Red Black and Green by : Alphonso Pinkney
Download or read book Red Black and Green written by Alphonso Pinkney and published by Cambridge University Press. This book was released on 1976-04-30 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the first slaves who rose up against their master in the early period of American history to the prominent modern figures such as Malcolm X, Elijah Muhammed, Eldridge Cleaver, Red, Black, and Green traces the origins, the struggles and the accomplishments of black nationalism. Its broad discussion of the ideology of black nationalism and of the conditions that gave rise to this ideology provides the foundation for a thorough account of the black nationalist movement in the peak years of its momentum, roughly the decade 1963 to 1973. The author deals both with specific milestones, such as Marcus Garvey's Universal Negro Improvement Association in the early twentieth century, and with the far-reaching implications of the movement for the black community and for the United States as a whole. He looks at the many facets of black nationalism - revolutionary nationalism, cultural nationalism, religious nationalism, and educational nationalism - analyses the relationship between this movement and liberation movements in general.
Book Synopsis Etruscan Civilization by : Sybille Haynes
Download or read book Etruscan Civilization written by Sybille Haynes and published by Getty Publications. This book was released on 2000 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive survey of Etruscan civilization, from its origin in the Villanovan Iron Age in the ninth century B.C. to its absorption by Rome in the first century B.C., combines well-known aspects of the Etruscan world with new discoveries and fresh insights into the role of women in Etruscan society. In addition, the Etruscans are contrasted to the Greeks, whom they often emulated, and to the Romans, who at once admired and disdained them. The result is a compelling and complete picture of a people and a culture. This in-depth examination of Etruria examines how differing access to mineral wealth, trade routes, and agricultural land led to distinct regional variations. Heavily illustrated with ancient Etruscan art and cultural objects, the text is organized both chronologically and thematically, interweaving archaeological evidence, analysis of social structure, descriptions of trade and burial customs, and an examination of pottery and works of art.
