Download or read book Planification de trajectoire et commande pour les robots mobiles non holonomes written by Yingchong Ma and published by . This book was released on 2013 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ce travail propose de nouvelles stratégies pour la planification et le contrôle des robots mobiles non-holonomes, de nouveaux algorithmes sont proposés. Tout d'abord, l'identification des différents modèles cinématiques de robot mobiles est discutée, et le problème est formulé comme l'identification en temps réel du signal de commutation d'un système singulier non-linéaire et à commutation. Deuxièmement, sur la base du modèle identifié, un algorithme de planification locale est proposé, et le contour irrégulier de l' obstacle est représenté par des segments. La trajectoire est obtenue en résolvant un problème de commande optimale avec contraintes. Troisièmement, nous appliquons un contrôleur i-PID pour contrôler le robot mobile non-holonome avec la perturbation dans les mesures. Un paramètre de commutation [alpha] est proposé en raison de la particularité du système non-holonome. En plus de notre algorithme de planification proposé, une autre approche de planification en utilisant de champs de potentiels est proposée. La nouvelle fonction de champ de potentiel est en mesure de résoudre les problèmes de minima locaux et de produire des forces lisses pour éviter les oscillations. Enfin, une approche de planification coopérative entre robots est proposée en utilisant les informations locales partagées par chaque robot. Le graphe de visibilité est utilisé pour générer une série d'objectifs intermédiaires qui assureront aux robots d'atteindre l'objectif final, et un algorithme est proposé pour étendre les obstacles et fusionner les obstacles lorsque deux obstacles s'entrecroisent.
Download or read book Planification de Trajectoire Et Navigation Des Robots Mobiles written by Nouara Achour and published by Omniscriptum. This book was released on 2011-04 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les robots mobiles autonomes sont un sujet de recherche et de préoccupation dans de nombreux domaines comme les manufactures et l'exploration spatiale. La planification de trajectoire est l'une des problématiques essentielles de l'autonomie des robots mobiles, elle a pour but de générer une trajectoire libre de collisions entre une configuration initiale et une configuration finale d'un robot. Dans cet ouvrage nous avons traité le problème de la planification de trajectoire sous trois aspects; un environnement entièrement connu, partiellement connu et complètement inconnu. Pour les environnements statiques et entièrement connus, une alternative à la méthode de Lozano Perez est proposée pour déterminer l'espace de configuration d'un robot. La méthode proposée a le mérite d'ètre simple et permet d'optimiser l'espace libre du robot. Nous abordons également le problème de la navigation réactive dans des environnements dynamiques ainsi que la construction de cartes d'environnements. Nous proposons une approche hybride qui intègre la représentation de la logique floue d'une base de connaissance intelligente avec la capacité d'apprentissage des réseaux de neurones.

Download or read book Social Media in Industrial China written by Xinyuan Wang and published by UCL Press. This book was released on 2016-09-13 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Life outside the mobile phone is unbearable.’ Lily, 19, factory worker. Described as the biggest migration in human history, an estimated 250 million Chinese people have left their villages in recent decades to live and work in urban areas. Xinyuan Wang spent 15 months living among a community of these migrants in a small factory town in southeast China to track their use of social media. It was here she witnessed a second migration taking place: a movement from offline to online. As Wang argues, this is not simply a convenient analogy but represents the convergence of two phenomena as profound and consequential as each other, where the online world now provides a home for the migrant workers who feel otherwise ‘homeless’. Wang’s fascinating study explores the full range of preconceptions commonly held about Chinese people – their relationship with education, with family, with politics, with ‘home’ – and argues why, for this vast population, it is time to reassess what we think we know about contemporary China and the evolving role of social media.
Download or read book Signal Processing for Communications written by Paolo Prandoni and published by Collection Savoir suisse. This book was released on 2008-06-17 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: With a novel, less classical approach to the subject, the authors have written a book with the conviction that signal processing should be taught to be fun. The treatment is therefore less focused on the mathematics and more on the conceptual aspects, the idea being to allow the readers to think about the subject at a higher conceptual level, thus building the foundations for more advanced topics. The book remains an engineering text, with the goal of helping students solve real-world problems. In this vein, the last chapter pulls together the individual topics as discussed throughout the book into an in-depth look at the development of an end-to-end communication system, namely, a modem for communicating digital information over an analog channel.
Download or read book Cambridge Handbook of Engineering Education Research written by Aditya Johri and published by Cambridge University Press. This book was released on 2014-02-10 with total page 1124 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Cambridge Handbook of Engineering Education Research is the critical reference source for the growing field of engineering education research, featuring the work of world luminaries writing to define and inform this emerging field. The Handbook draws extensively on contemporary research in the learning sciences, examining how technology affects learners and learning environments, and the role of social context in learning. Since a landmark issue of the Journal of Engineering Education (2005), in which senior scholars argued for a stronger theoretical and empirically driven agenda, engineering education has quickly emerged as a research-driven field increasing in both theoretical and empirical work drawing on many social science disciplines, disciplinary engineering knowledge, and computing. The Handbook is based on the research agenda from a series of interdisciplinary colloquia funded by the US National Science Foundation and published in the Journal of Engineering Education in October 2006.

Download or read book Principles of European Contract Law and Italian Law written by Luisa Antoniolli and published by Kluwer Law International B.V.. This book was released on 2005-01-01 with total page 522 pages. Available in PDF, EPUB and Kindle. Book excerpt: To provide valuable legal service to persons in today's Europe, practitioners must be conversant in both national and transnational law. At the European level, the Principles of European Contract Law (PECL) are an increasingly important element of contract law, together with national contract law, as contained in Civil Codes and various national statute. Accordingly, Kluwer Law International has initiated a series of volumes, under the direction of prof. Hondius of the University of Utrecht, comparing PECL with the most important European legal systems. This volume on Italian law is the second in the series. Using a straightforward comparative method, the editors¿ analysis not only reveals a significant area of convergence between the PECL and Italian contract law, but also highlights the main differences between the two bodies of rules. The reasons for these differences, both legal and non-legal (such as historical, social, economic), are clearly set forth. The book provides complete texts, with annotations, of the PECL and the corresponding Italian rules. The presentation proceeds as follows: general provisions (scope of application, general duties, terminology)formation of contracts (general provisions, offer and acceptance, liability for negotiations)authority of agents (general provisions, direct and indirect representation)validityinterpretationcontents and effectsperformancenon-performance and remedies in generalparticular remedies for non-performance (right to performance, withholding performance, termination of the contract, price reduction, damages and interest) The editors commentary includes extensive reference to case law and legal doctrine at all essential points. In this way they provide a comprehensive description of the law in action as well as its evolving trends. In addition, incisive essays by two leading experts in the field of comparative law, prof. Rodolfo Sacco and prof. Michael Joachim Bonell, analyse the relationship of the PECL and Italian law and its wider framework in the harmonisation of private law at the European and international levels. The book is a valuable handbook and guide for both foreign and Italian lawyers. For non-Italian lawyers, be they practitioners or academics, it provides a concise but complete and up-to-date outline of current Italian contract law, organized on the basis of a system (PECL) with which many European lawyers are familiar. For Italian lawyers, it offers a clearer insight into a wider European legal contract system whose importance in the evolution of a common European private law is growing rapidly.

Download or read book The Physics of Information Technology written by Neil Gershenfeld and published by Cambridge University Press. This book was released on 2000-10-16 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Physics of Information Technology explores the familiar devices that we use to collect, transform, transmit, and interact with electronic information. Many such devices operate surprisingly close to very many fundamental physical limits. Understanding how such devices work, and how they can (and cannot) be improved, requires deep insight into the character of physical law as well as engineering practice. The book starts with an introduction to units, forces, and the probabilistic foundations of noise and signalling, then progresses through the electromagnetics of wired and wireless communications, and the quantum mechanics of electronic, optical, and magnetic materials, to discussions of mechanisms for computation, storage, sensing, and display. This self-contained volume will help both physical scientists and computer scientists see beyond the conventional division between hardware and software to understand the implications of physical theory for information manipulation.

This book was released on 2006-06-15 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quantum information and computation is a rapidly expanding and cross-disciplinary subject. This book, first published in 2006, gives a self-contained introduction to the field for physicists, mathematicians and computer scientists who want to know more about this exciting subject. After a step-by-step introduction to the quantum bit (qubit) and its main properties, the author presents the necessary background in quantum mechanics. The core of the subject, quantum computation, is illustrated by a detailed treatment of three quantum algorithms: Deutsch, Grover and Shor. The final chapters are devoted to the physical implementation of quantum computers, including the most recent aspects, such as superconducting qubits and quantum dots, and to a short account of quantum information. Written at a level suitable for undergraduates in physical sciences, no previous knowledge of quantum mechanics is assumed, and only elementary notions of physics are required. The book includes many short exercises, with solutions available to instructors through [email protected].
Download or read book Digital Transformation in Financial Services written by Claudio Scardovi and published by Springer. This book was released on 2017-09-04 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book analyzes the set of forces driving the global financial system toward a period of radical transformation and explores the transformational challenges that lie ahead for global and regional or local banks and other financial intermediaries. It is explained how these challenges derive from the newly emerging post-crisis structure of the market and from shadow and digital players across all banking operations. Detailed attention is focused on the impacts of digitalization on the main functions of the financial system, and particularly the banking sector. The author elaborates how an alternative model of banking will enable banks to predict, understand, navigate, and change the external ecosystem in which they compete. The five critical components of this model are data and information mastering; effective use of applied analytics; interconnectivity and “junction playing”; development of new business solutions; and trust and credibility assurance. The analysis is supported by a number of informative case studies. The book will be of interest especially to top and middle managers and employees of banks and financial institutions but also to FinTech players and their advisers and others.

Download or read book Unpacking IKEA written by Pauline Garvey and published by Routledge. This book was released on 2017-11-23 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book represents the first anthropological ethnography of Ikea consumption and goes to the heart of understanding the unique and at times frantic popularity of this one iconic transnational store. Based on a year of participant observation in Stockholm’s Kungens Kurva store – the largest in the world - this book places the retailer squarely within the realm of the home-building efforts of individuals in Stockholm and to a lesser degree in Dublin. Ikea, the world’s largest retailer and one of its most interesting, is the focus of intense popular fascination internationally, yet is rarely subject to in-depth anthropological inquiry. In Unpacking Ikea, Garvey explores why Ikea is never ‘just a store’ for its customers, and questions why it is described in terms of a cultural package, as everyday and classless. Using in-depth interviews with householders over several years, this ethnographic study follows the furniture from the Ikea store outwards to probe what people actually take home with them.
