Book Description
Tout réseau peut subir l’intermittence et l’instabilité de son efficacité. L’utilisation de la théorie des jeux dans ce domaine particulier contribue à une allocation efficace des ressources et par là-même à un meilleur équilibre du réseau. Après avoir présenté les notions introductives aux réseaux sans fil et leurs différentes caractéristiques, cet ouvrage développe le principe et les règles capitales de la théorie des jeux, notamment à travers l’approche existante au sein des télécommunications. Le jeu de codes utilisé permet ensuite de formaliser le comportement des noeuds pendant la transmission au sein des réseaux SALOHA et CSMA. Le modèle unique proposé dans Coopération dans les réseaux ad hoc par application de la théorie des jeuxdéveloppe l’utilisation aléatoire de la redondance d’un codeur à effacement afin de diminuer la collision et d’améliorer les performances du réseau en termes de débit et de délai de transmission. Les résultats obtenus et les simulations effectuées convergent vers une solution pure et stable qui amène à une plus grande efficacité du réseau.

Book Description
"The merchants of the medieval Hanse monopolised trade in the Baltic and North Sea areas. The authors describe the structure of their trade system in terms of network organisation and attempts to explain, on the grounds of institutional economics, the coordination of the merchants' commercial exchange by reputation, trust and culture. The institutional economics approach also allows for a comprehensive analysis of coordination problems arising between merchants, towns and the 'Kontore.' Due to the simplicity and flexibility of network trade, the Hansards could bridge the huge gap in economic development between the West and the East. In the changing economic conditions around 1500, however, exactly these characteristics proved to be a serious limit to further retain their trade monopoly"--Provided by publisher.

Book Description
Information technology has been used in organisational settings and for organisational purposes such as accounting, for a half century, but IT is now increasingly being used for the purposes of mediating and regulating complex activities in which multiple professional users are involved, such as in factories, hospitals, architectural offices, and so on. The economic importance of such coordination systems is enormous but their design often inadequate. The problem is that our understanding of the coordinative practices for which these systems are developed is deficient, leaving systems developers and software engineers to base their designs on commonsensical requirements analyses. The research reflected in this book addresses these very problems. It is a collection of articles which establish a conceptual foundation for the research area of Computer-Supported Cooperative Work.

Book Description
This textbook presents the core of recent advances in design theory and its implications for design methods and design organization. Providing a unified perspective on different design methods and approaches, from the most classic (systematic design) to the most advanced (C-K theory), it offers a unique and integrated presentation of traditional and contemporary theories in the field. Examining the principles of each theory, this guide utilizes numerous real life industrial applications, with clear links to engineering design, industrial design, management, economics, psychology and creativity. Containing a section of exams with detailed answers, it is useful for courses in design theory, engineering design and advanced innovation management. "Students and professors, practitioners and researchers in diverse disciplines, interested in design, will find in this book a rich and vital source for studying fundamental design methods and tools as well as the most advanced design theories that work in practice". Professor Yoram Reich, Tel Aviv University, Editor-in-Chief, Research In Engineering Design. "Twenty years of research in design theory and engineering have shown that training in creative design is indeed possible and offers remarkably operational methods - this book is indispensable for all leaders and practitioners who wish to strengthen theinnovation capacity of their company."

Book Description
The globalization of threats and the complexity of international security issues represents a greater challenge for international policing in (re)shaping inter-agency interaction, and makes effective international police cooperation more necessary than ever before. This book sets out to analyse the key emerging issues and theory and practice of international police cooperation. Paying special attention to the factors that have contributed to the effective working of police cooperation in practice and the problems that are encountered, this book brings together original research that examines opportunities and initiatives undertaken by agencies (practices and processes introduced) as well as the impact of external legal, political, and economical pressures. Contributors explore emerging initiatives and new challenges in several contexts at both national and international levels. They adopt a diversity of approaches and theoretical frameworks to reach a broader understanding of current and future issues in police cooperation. Forms of police cooperation and trends in crime control are examined, drawing upon the following disciplines: criminology, ethics, organizational science, political science, and sociology.

Book Description
Since the Doi Moi policy of economic renovation was introduced in 1986, Vietnam has undergone deep transformations as a result of the transition to a socialist-oriented market economy. Social and urban transition has taken place in parallel, as urban dynamics were spurred on by Vietnamese public and private stakeholders, and by external agents such as international organizations and international solidarity organizations, experts, consultants and bilateral aid organizations.Here are the results of research carried out by French, Canadian and Vietnamese teams from the north and south of the country on the overarching theme of Vietnamese cities in transition. Some of this research deals with urban dynamics, some with the issues at stake within such dynamics, or with the strategies of the most significant stakeholders in urban transition: civil society, donors within the framework of official aid for development, consultants and international consultancy firms. These projects were carried out between 2001 and 2004 as part of the Urban Research Programme for Development (PRUD), and mainly focus on Hanoi and Ho Chi Minh City, or both in the case of comparative studies.Is there such a thing as a Vietnamese model of an Asian city? It seems that urban transition in Vietnam is not taking place in as radical and abrupt a manner as in China. The country's capacity for absorbing external models, the quest for a third way between state intervention and economic liberalism, and the fact that the country's architectural heritage is taken into account in urban planning, are just some of the reasons for its particularity. The issues addressed in each chapter, as well as the proposals for further research suggested by the contributors, should act as a catalyst for urban research in Vietnam.

Book Description
Bourdieu and Literature is a wide-ranging, rigorous and accessible introduction to the relationship between Pierre Bourdieu's work and literary studies. It provides a comprehensive overview and critical assessment of his contributions to literary theory and his thinking about authors and literary works. One of the foremost French intellectuals of the post-war era, Bourdieu has become a standard point of reference in the fields of anthropology, linguistics, art history, cultural studies, politics, and sociology, but his longstanding interest in literature has often been overlooked. This study explores the impact of literature on Bourdieu's intellectual itinerary, and how his literary understanding intersected with his sociological theory and thinking about cultural policy. This is the first full-length study of Bourdieu's work on literature in English, and it provides an invaluable resource for students and scholars of literary studies, cultural theory and sociology.

Book Description
This book provides glimpses into contemporary research in information systems & technology, learning, artificial intelligence (AI), machine learning, and security and how it applies to the real world, but the ideas presented also span the domains of telehealth, computer vision, the role and use of mobile devices, brain–computer interfaces, virtual reality, language and image processing and big data analytics and applications. Great research arises from asking pertinent research questions. This book reveals some of the authors’ “beautiful questions” and how they develop the subsequent “what if” and “how” questions, offering readers food for thought and whetting their appetite for further research by the same authors.
