Book excerpt: NOUS INTERPRETONS LA DETECTION DE SYMBOLES PAR MAXIMUM DE VRAISEMBLANCE (DSMV) DANS UN CONTEXTE MULTIVOIE EN TERMES D'ANNULATION DES INTERFERENCES CO-CANAL. L'ASPECT MULTIVOIE PEUT APPARAITRE LORSQU'ON UTILISE PLUSIEURS ANTENNES A LA RECEPTION, OU EN SURECHANTILLONNANT LE SIGNAL RECU PAR RAPPORT A LA CADENCE DES SYMBOLES TRANSMIS, OU EN EXPLOITANT LES PARTIES EN PHASE ET EN QUADRATURE DANS LE CAS DE SYMBOLES REELS. NOUS DEMONTRONS GRACE A LA BORNE DU FILTRE ADAPTE QU'UNE AMELIORATION SIGNIFICATIVE DES PERFORMANCES PEUT RESULTER DE LA PRISE EN COMPTE DES CORRELATIONS SPATIO-TEMPORELLES DES INTERFERENCES DANS LA METRIQUE DE L'ALGORITHME DE VITERBI. NOUS INTERPRETONS LA DSMV, DANS LE CAS MULTIVOIE, COMME LA CASCADE DE DEUX OPERATIONS : LA REDUCTION DES INTERFERENCES ET L'EGALISATION D'UN CANAL MONOVOIE. NOUS DEMONTRONS QUE LA PREMIERE OPERATION EST UNE GENERALISATION AU CAS SPATIO-TEMPOREL D'UN RECEPTEUR SPATIAL BIEN CONNU EN TRAITEMENT D'ANTENNE ET QUE L'EGALISEUR OPTIMAL EST CELUI UTILISANT L'ALGORITHME DE VITERBI. DU MOMENT OU LA COMPLEXITE DE CE DERNIER DEVIENT PROHIBITIVE DANS LE CAS D'UNE LARGE CONSTELLATION, NOUS PROPOSONS D'EGALISER LES ZEROS DU CANAL MONOVOIE QUI SE TROUVENT ASSEZ LOIN DU CERCLE UNITE. SACHANT QUE LA REPONSE IMPULSIONNELLE D'UN CANAL RADIO EST LA CASCADE DU FILTRE DE TRANSMISSION (MODULATEUR), DU CANAL DE PROPAGATION ET DU FILTRE DE RECEPTION, ON PEUT ECRIRE LA VERSION ECHANTILLONNEE DE LA REPONSE IMPULSIONNELLE COMME LA CONVOLUTION D'UN FILTRE DE MISE EN FORME (MODULATEUR ET FILTRE DE RECEPTION) ECHANTILLONNE ET D'UNE VERSION ECHANTILLONNEE DU CANAL DE PROPAGATION FILTRE PAR UN FILTRE PASSE-BAS SI LA FREQUENCE D'ECHANTILLONNAGE SATISFAIT LE CRITERE DE NYQUIST. LE FILTRE DE MISE EN FORME, COMMUN A TOUS LES UTILISATEURS, EST ALORS EGALISE PARTIELLEMENT AFIN D'AMELIORER L'ESTIMATION DES QUANTITES NECESSAIRES A LA MISE EN UVRE DU RECEPTEUR. LA QUALITE D'ESTIMATION DE CES QUANTITES PEUT ETRE AMELIOREE SI UN ALGORITHME DE SAUT DE FREQUENCES CYCLIQUE EST UTILISE DANS UN SYSTEME MOBILE CELLULAIRE QUASI-SYNCHRONE. LA PERFORMANCE DE CETTE APPROCHE EST LIMITEE, ESSENTIELLEMENT, PAR L'EXCES EN LARGEUR DE BANDE DU FILTRE DE MISE EN FORME. NOUS DEMONTRONS QUE LE RECEPTEUR PROPOSE EST EQUIVALENT A UN FILTRE DE WIENER VECTORIEL SI L'EGALISEUR MONOVOIE EST UN EGALISEUR LINEAIRE MINIMISANT L'ERREUR QUADRATIQUE MOYENNE. NOUS AVONS EXPLOITE LE FAIT QUE CE RECEPTEUR PERMET UNE CERTAINE REDUCTION DES INTERFERENCES POUR AMELIORER LA QUALITE D'ESTIMATION DU CANAL D'UN UTILISATEUR DONNE. EN SUPPOSANT QUE LA SEQUENCE D'ENTREE EST GAUSSIENNE, NOUS AVONS PROPOSE DEUX CRITERES DE MOINDRES CARRES OPTIMALEMENT PONDERES POUR L'ESTIMATION DU CANAL DONT LES PERFORMANCES ATTEINTES EN PRATIQUE PEUVENT ETRE PROCHES DE CELLES CORRESPONDANT A UNE METHODE SEMI-AVEUGLE SI L'ESTIMATION DU SPECTRE DU SIGNAL RECU EST BONNE.

Download or read book Infelicities written by Peter Mason and published by JHU Press. This book was released on 1998 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Infelicities Peter Mason explores the texts, paintings, drawings, photographs, and museum displays in which the exotic has been represented from the early modern period to the present. He describes the unique iconography that Europeans developed to convey the exotic and the means they employed to display it once artifacts were brought to Europe. In both instances, the exotic object is taken out of its original context and given a meaning and significance it never had; this new meaning and significance, Mason argues, are derived from the imposition of European cultural values and the need to recontextualize the object in a European setting.

Download or read book Cannibal Encounters written by Philip P. Boucher and published by JHU Press. This book was released on 2009-05-25 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: A history and analysis of European colonizers’ relationship with and literary depiction of the aborigines of the Lesser Antilles. Philip Boucher analyzes the images—and the realities—of European relations with the people known as Island Caribs during the first three centuries after Columbus. Based on literary sources, travelers’ observations, and missionary accounts, as well as on French and English colonial archives and administrative correspondence, Cannibal Encounters offers a vivid portrait of a troubled chapter in the history of European-Amerindian relations. Winner of the French Colonial Historical Society’s Alf Andrew Heggoy Book Prize “A strong contribution to our understanding of the interplay not only between France and Britain in the struggle for the Antilles but also between the colonizers and the indigenous people fighting to maintain their independence from both European powers.” —American Historical Review “Welcome evidence that historians are willing to rewrite the history of the colonial era in the Caribbean with a clearer eye to the part the indigenous population played.” —Peter Hulme, William and Mary Quarterly “Boucher’s research is thorough and his contribution to the historiography of the Caribbean and of colonialism is valuable.” —Ethan Casey, Magill Book Reviews “An intelligent, well-informed discussion of French and English contacts with Island Caribs in the West Indies from the pre-colonial era until the end of the Seven Years War.” —Kenneth Morgan, English Historical Review “A new and important contribution to the efforts of historians and anthropologists to understand the history of the Caribs.” —Jalil Sued-Badillo, Journal of American History “A lucid and terse examination of direct interactions between Island Caribs and Europeans in the Lesser Antilles, and the indirect influence of literary images of Island Caribs (and other Native Americans) on the emergence of Western philosophical traditions.” —William F. Keegan, Journal of Interdisciplinary History “No one has mined the French National Archives to this extent on this topic. Boucher renders valuable information accessible to English readers.” —Robert A. Myers, Alfred University

Download or read book Main Currents in Caribbean Thought written by Gordon K. Lewis and published by U of Nebraska Press. This book was released on 2004-01-01 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: Main Currents in Caribbean Thought probes deeply into the multicultural origins of Caribbean society, defining and tracing the evolution of the distinctive ideology that has arisen from the region’s unique historical mixture of peoples and beliefs. Among the topics that noted scholar Gordon K. Lewis covers are the sixteenth- and seventeenth-century beginnings of Caribbean thought, pro- and antislavery ideologies, the growth of Antillean nationalist and anticolonialist thought during the nineteenth century, and the development of the region’s characteristic secret religious cults from imported religions and European thought. Since its original publication in 1983, Main Currents in Caribbean Thought has remained one of the most ambitious works to date by a leader in modern Caribbean scholarship. By looking into the “Caribbean mind,” Lewis shows how European, African, and Asian ideas became creolized and Americanized, creating an entirely new ideology that continues to shape Caribbean thought and society today.

Download or read book The Colonial Machine written by James Edward McClellan (III) and published by Brepols Publishers. This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rise of modern science and European colonial and imperial expansion are indisputably two defining elements of modern world history. James E. McClellan III and Francois Regourd explore these two world-historical forces and their interactions in this comprehensive and in-depth history of the French case in the Old Regime presented here for the first time. The case is key because no other state matched Old-Regime France as a center for organized science and because contemporary France closely rivaled Britain as a colonial power, as well as leading all other nations in commodity production and participating in the slave trade. Based on extensive archival research and vast primary and secondary literatures and sharply reframing the historiography of the field, this landmark volume traces the development and significance for early-modern history of the Colonial Machine of Old-Regime France, an unparalleled agglomeration of institutions geared to the success of the French colonial enterprise, including the Royal Navy, the Academie Royale des Sciences, the Jardin du Roi, and a host of related specialist institutions working together at home and overseas. Mainly supported by the French state, the Colonial Machine reveals itself through its actions from the time of Colbert and Louis XIV as it grappled with fundamental problems facing contemporary European colonialism: cartography and navigation; medical care of sailors, colonists, and slaves; and applied botany and commodity production. Historians of globalization and European overseas expansion, of Old-Regime France, and of science in the seventeenth and eighteenth centuries will henceforth take this stimulating volume as a necessary starting point for further reflection and research. Nominated for the Mary Alice and Philip Boucher Book Prize.

Download or read book Complexities written by John Law and published by Duke University Press. This book was released on 2002-06-10 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although much recent social science and humanities work has been a revolt against simplification, this volume explores the contrast between simplicity and complexity to reveal that this dichotomy, itself, is too simplistic. John Law and Annemarie Mol have gathered a distinguished panel of contributors to offer—particularly within the field of science studies—approaches to a theory of complexity, and at the same time a theoretical introduction to the topic. Indeed, they examine not only ways of relating to complexity but complexity in practice. Individual essays study complexity from a variety of perspectives, addressing market behavior, medical interventions, aeronautical design, the governing of supranational states, ecology, roadbuilding, meteorology, the science of complexity itself, and the psychology of childhood trauma. Other topics include complex wholes (holism) in the sciences, moral complexity in seemingly amoral endeavors, and issues relating to the protection of African elephants. With a focus on such concepts as multiplicity, partial connections, and ebbs and flows, the collection includes narratives from Kenya, Great Britain, Papua New Guinea, the Netherlands, France, and the meetings of the European Commission, written by anthropologists, economists, philosophers, psychologists, sociologists, and scholars of science, technology, and society. Contributors. Andrew Barry, Steven D. Brown, Michel Callon, Chunglin Kwa, John Law, Nick Lee, Annemarie Mol, Marilyn Strathern, Laurent Thévenot, Charis Thompson

Download or read book Building Theories of Organization written by Linda L. Putnam and published by Routledge. This book was released on 2009-01-13 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume explores the concept of communication as it applies to organizational theory. Bringing together multiple voices, it focuses on communication’s role in the constitution of organization. Editors Linda L. Putnam and Anne Maydan Nicotera have assembled an all-star cast of contributors, each providing a distinctive voice and perspective. The contents of this volume compare and contrast approaches to the notion that communication constitutes organization. Chapters also examine the ways that those processes produce patterns that endure over time and that constitute the organization as a whole. This collection bridges different disciplines and serves a vital role in developing dimensions, characteristics, and relationships among concepts that address how communication constitutes organization. It will appeal to scholars and researchers working in organizational communication, organizational studies, management, sociology, social collectives, and organizational psychology and behavior.

Download or read book Democracy Challenged written by Marina Ottaway and published by Carnegie Endowment. This book was released on 2013-01-25 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the 1990s, international democracy promotion efforts led to the establishment of numerous regimes that cannot be easily classified as either authoritarian or democratic. They display characteristics of each, in short they are semi-authoritarian regimes. These regimes pose a considerable challenge to U.S. policymakers because the superficial stability of many semi-authoritarian regimes usually masks severe problems that need to be solved lest they lead to a future crisis. Additionally, these regimes call into question some of the ideas about democratic transitions that underpin the democracy promotion strategies of the United States and other Western countries. Despite their growing importance, semi-authoritarian regimes have not received systematic attention. Marina Ottaway examines five countries (Egypt, Azerbaijan, Venezuela, Croatia, and Senegal) which highlight the distinctive features of semi-authoritarianism and the special challenge each poses to policymakers. She explains why the dominant approach to democracy promotion isn't effective in these countries and concludes by suggesting alternative policies. Marina Ottaway is senior associate and codirector of the Democracy and Rule of Law Project at the Carnegie Endowment.

Download or read book The Situated Organization written by James R. Taylor and published by Routledge. This book was released on 2010-09-13 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Situated Organization explores recent research in organizational communication, emphasizing the organization as constructed in and emerging out of communication practices. Working from the tradition of the Montreal School in its approach, it focuses not only on how an organization’s members understand the purposes of the organization through communication, but also on how they realize and recognize the organization itself as they work within it. The text breaks through with an alternative viewpoint to the currently popular idea of 'organization-as-network,' viewing organization instead as a configuration of agencies, and their fields of practice. It serves as an original, comprehensive, and well-written text, elaborated by case studies that make the theory come to life. The substantial ideas and insights are presented in a deep and meaningful way while remaining comprehensible for student readers. This text has been developed for students at all levels of study in organizational communication, who need a systematic introduction to conducting empirical field research. It will serve as an invaluable sourcebook in planning and conducting research.

Book excerpt: Blockbusting film GOLDA starring Helen Mirren is out now 'The gripping memoir of a remarkable woman who rose to the top in a man's world. A compelling political story of courage and struggle, power and leadership, war and crisis - and the making of Israel. A classic of 20th century history' Simon Sebag Montefiore, author of JERUSALEM: THE BIOGRAPHY 'A remarkable, almost incredible personal history ... stimulating and fascinating' IRISH TIMES 'A rare and wholly unforgettable work' SATURDAY REVIEW WITH A NEW INTRODUCTION BY JULIA NEUBERGER Golda Meir was without doubt one of the most incredible women of her - and any - time. Born in 1898 in Kyiv, she was the daughter of an impoverished carpenter - and became the first (and only) female Prime Minister of Israel. Meir's earliest memory is of her father boarding up the front door in response to rumours of an imminent pogrom. The family emigrated to the US and for a while Meir lived with her sister, where she was exposed to debates on Zionism, women's suffrage, literature and socialism. She became a teacher, and after her marriage emigrated again to Palestine, settling on a kibbutz. Always politically active, she became Israel's first envoy to Moscow; was promoted to Foreign Minister and ultimately elected as Prime Minister, leader of Israel. In her autobiography she wrote: 'To me, being Jewish means and has always meant being proud to be part of a people that has maintained its distinct identity for more than 2,000 years, with all the pain and torment that has been inflicted upon it'

Download or read book Urban Poverty in Developing Countries written by Ranvinder Singh Sandhu and published by . This book was released on 2009 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Urbanization got an impetus during 1980s and 1990s due to advances in transportation and telecommunicationand further momentum was provided by globalization. During this period many Asian Countries experienced both economic boom and population increase. UN HABITAT (2006) pointed out that Asia and Africa will host largest urban population in 21st century and cities will continue to be sites of extreme inequality. It is feared that Asian cities may not be able to cope with the ongoing urbanization and urbanization of poverty further adds to the challenges. This edited volume addresses to the challenges thrown by urban poverty for sustainable cities in developing countries and also presents some strategies adopted in these countries to deal with these challenges. The volume contains seventeen articles which are divided into three sections. Section-1, entitled 'Urban Poverty in Developing Countries: Some Issues', contains five articles dealing with urban poverty and delineates certain issues related to it. Section-II, entitled 'Urban Poverty in India: Empirical Reality', contains five articles which present the empirical situation of urban poverty in India. Section-III, entitled 'Urban poverty and Strategies for Sustainable Cities', anthologizes seven articles dealing with some strategies to grapple with the problem of urban poverty in developing countries and the outcome of these efforts. All these efforts to achieve sustainable cities are not producing desired results. Cities cannot be sustainable if rural areas, neighborhoods and communities are not sustainable. So focus must shift to these settlements as well.
