This paper presents an approach based on cooperative selforganization for arti cial systems, in order to tackle openness and dynamics. We propose to use cooperation as a local criterion enabling parts of the system the cooperative agents to reorganize as to modify their interactions and then the global function. We underline the di culty of de ning cooperation and the means to reestablish a coo...

To develop a computer system to support cooperative learning among distributed students; developers should consider the foundations of cooperative learning. This article examines the basic elements that make cooperation work and proposes a framework for such computer supported cooperative learning (CSCL) systems. This framework consists of five main components to support cooperative group struc...

Over the last decade, Computer Supported Cooperative Work (CSCW) has emerged as an identifiable research area which focuses on the role of the computer in group work. CSCW is a generic term which combines the understanding of the nature of group working with the enabling technologies of computer networking, systems support and applications. This paper examines the classes of system which have e...

We are in the process of design of an intelligent cooperative system in a nuclear plant application. The system must cooperate with an operator who accomplishes a task of supervision of a real-world process. We point out in the paper that a cooperation between a cooperative system and an operator has two modes: a waking state and a participating state. During the waking state, the system observ...

This paper presents an approach based on cooperative self-organization for artificial systems, in order to tackle openness and dynamics. In this work, cooperation is used as a local criterion enabling parts of the system –the cooperative agents– to reorganize as to autonomously modify their interactions and then the global function. The difficulty in defining cooperation and the means to reesta...

In recent years, cooperative communications are widely studied. Cooperative communications can obtain the space diversity as multiple-input multiple-output (MIMO) systems. In cooperative communications, the relay method is important as decode-and-forward (DF) and decode-amplify-forward (DAF). The multi-relay cooperative communications can improve the system performance. In the multi-relay coope...

based on existing literature social capital is defined as a set of norms and rules and informal networks that provide association, trust and collective action to obtain the public good. the empowerment projects of world bank that has been implemented in many third world countries in the late 1980s followed by a non-reductionist non- physical approach integration of cultural and socio- economic ...

Cooperative communication is a novel class of wireless communication technique which wireless nodes help each other relay information to the intended destination. Orthogonal frequency division multiplexing (OFDM) has become a popular technique for the high data rate and performance. The integration of OFDM and cooperative communication in next generation wireless leads to the design of an effic...

This paper presents a cooperative perception system for multiple heterogeneous UAVs. It considers different kind of sensors: infrared and visual cameras and fire detectors. The system is based on a set of multipurpose low-level image-processing functions including segmentation, stabilization of sequences of images and geo-referencing, and it also involves data fusion algorithms for cooperative ...
