Book Synopsis Conception d'un système de communication ultra large bande appliqué aux transports by : Fouzia El Bahhar
Download or read book Conception d'un système de communication ultra large bande appliqué aux transports written by Fouzia El Bahhar and published by . This book was released on 2003 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'objectif de ce travail est d'explorer une des composantes des systèmes de transport intelligent : la communication inter véhicules. Dans ce cadre, plusieurs études théoriques ont été effectuées pour évaluer les performances d'un système de communication basé sur une nouvelle technologie dite Ultra Large Bande (ULB). D'autres études théoriques ont été effectuées pour tester la possibilité d'obtenir un système ULB à accès multiple en utilisant des fonctions orthogonales. Après l'étape de simulation, une maquette a été réalisée pour procéder aux premiers tests qui visent à évaluer les performances de notre système en fonction de la forme d'onde, du type de modulation, de la portée entre l'émetteur et le récepteur et de l'antenne utilisée. Afin de conforter l'étude théorique présentée, des tests supplémentaires utilisant un prototype d'un système ULB basé sur l'impulsion monocycle et la modulation antipodale ont démontré la faisabilité de la technique pour une communication inter véhicules.
Book Synopsis Conception et modèlisattion d'un système de communication multi-utilisateurs basé sur la technique Ultra Large Bande by : Abdellah Lamari
Download or read book Conception et modèlisattion d'un système de communication multi-utilisateurs basé sur la technique Ultra Large Bande written by Abdellah Lamari and published by . This book was released on 2007 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: La technologie Ultra Large Bande est une technique de modulation radio basée sur l'émission d’impulsions de très courte durée assurant une transmission (sans porteuse) robuste dans un canal multi trajets dense avec un débit important et une bonne résolution. Elle offre une bonne et unique opportunité pour hybrider les fonctionnalités de localisation et de communications numériques sans fil. Les technologies de transmission et de localisation actuellement mises en œuvre ne permettent d’atteindre ni une précision de localisation suffisante, ni de réaliser une communication à débit moyen avec une portée importante. L’objectif du travail est d’explorer une technique basée sur des nouvelles formes d’ondes de Gegenbauer modifiées (MGF), assurant l’accès multiple pour des applications de détection d’obstacles (radar), de positionnement (dans les zones non couverte par le GPS) et de transmission de données pour les transports terrestres. Le système multi-bandes ultra large bande proposé dans cette thèse doit exploiter efficacement le gabarit de puissance imposé par les organismes internationaux comme la FCC et l’ETSI.

Book Synopsis Psychoanalysis of Technoscience by : Hub Zwart
Download or read book Psychoanalysis of Technoscience written by Hub Zwart and published by LIT Verlag Münster. This book was released on 2019 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a psychoanalysis of technoscience. Basic concepts and methods developed by Freud, Jung, Bachelard and Lacan are applied to case histories (palaeoanthropology, classical conditioning, virology). Rather than by disinterested curiosity, technoscience is driven by desire, resistance and the will to control. Moreover, psychoanalysis focusses on primal scenes (Dubois' quest for the missing link, Pavlov's discovery of the conditioned reflex) and opts for triangulation: comparing technoscience to "different scenes" provided by novels, so that Dubois's work is compared to missing link novels by Verne and London and Pavlov's experiments with Skinner's Walden Two, while virology is studied through the lens of viral fiction.

Download or read book Vulnerable written by Colleen M. Flood and published by University of Ottawa Press. This book was released on 2020-07-14 with total page 850 pages. Available in PDF, EPUB and Kindle. Book excerpt: The novel coronavirus SARS-CoV-2, which causes the disease known as COVID-19, has infected people in 212 countries so far and on every continent except Antarctica. Vast changes to our home lives, social interactions, government functioning and relations between countries have swept the world in a few months and are difficult to hold in one’s mind at one time. That is why a collaborative effort such as this edited, multidisciplinary collection is needed. This book confronts the vulnerabilities and interconnectedness made visible by the pandemic and its consequences, along with the legal, ethical and policy responses. These include vulnerabilities for people who have been harmed or will be harmed by the virus directly and those harmed by measures taken to slow its relentless march; vulnerabilities exposed in our institutions, governance and legal structures; and vulnerabilities in other countries and at the global level where persistent injustices harm us all. Hopefully, COVID-19 will forces us to deeply reflect on how we govern and our policy priorities; to focus preparedness, precaution, and recovery to include all, not just some. Published in English with some chapters in French.

Author :Paul Valéry Publisher :Peter Lang Gmbh, Internationaler Verlag Der Wissenschaften ISBN 13 : Total Pages :606 pages Book Rating :4.F/5 ( download)
Download or read book Notebooks written by Paul Valéry and published by Peter Lang Gmbh, Internationaler Verlag Der Wissenschaften. This book was released on 2000 with total page 606 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Cahiers/Notebooks of Paul Valéry are a unique form of writing. They reveal Valéry as one of the most radical and creative minds of the twentieth century, encompassing a wide range of investigation into all spheres of human activity. His work explores the arts, the sciences, philosophy, history and politics, investigating linguistic, psychological and social issues, all linked to the central questions, relentlessly posed: 'what is the human mind and how does it work?', 'what is the potential of thought and what are its limits?' But we encounter here too, Valéry the writer: exploratory, fragmentary texts undermine the boundaries between analysis and creativity, between theory and practice. Neither journal nor diary, eluding the traditional genres of writing, the Notebooks offer lyrical passages, writing of extreme beauty, prose poems of extraordinary descriptive power alongside theoretical considerations of poetics, ironic aphorisms and the most abstract kind of analysis. The concerns and the insights that occupied Valéry's inner voyages over more than 50 years remain as relevant as ever for the contemporary reader: for the Self that is his principal subject is at once singular and universal.
Book Synopsis Building Wireless Community Networks by : Rob Flickenger
Download or read book Building Wireless Community Networks written by Rob Flickenger and published by "O'Reilly Media, Inc.". This book was released on 2003 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: Building Wireless Community Networks is about getting people online using wireless network technology. The 802.11b standard (also known as WiFi) makes it possible to network towns, schools, neighborhoods, small business, and almost any kind of organization. All that's required is a willingness to cooperate and share resources. The first edition of this book helped thousands of people engage in community networking activities. At the time, it was impossible to predict how quickly and thoroughly WiFi would penetrate the marketplace. Today, with WiFi-enabled computers almost as common as Ethernet, it makes even more sense to take the next step and network your community using nothing but freely available radio spectrum. This book has showed many people how to make their network available, even from the park bench, how to extend high-speed Internet access into the many areas not served by DSL and cable providers, and how to build working communities and a shared though intangible network. All that's required to create an access point for high-speed Internet connection is a gateway or base station. Once that is set up, any computer with a wireless card can log onto the network and share its resources. Rob Flickenger built such a network in northern California, and continues to participate in network-building efforts. His nuts-and-bolts guide covers: Selecting the appropriate equipment Finding antenna sites, and building and installing antennas Protecting your network from inappropriate access New network monitoring tools and techniques (new) Regulations affecting wireless deployment (new) IP network administration, including DNS and IP Tunneling (new) His expertise, as well as his sense of humor and enthusiasm for the topic, makes Building Wireless Community Networks a very useful and readable book for anyone interested in wireless connectivity.
