Cooperative information agents need mechanisms that enable them to work together eeectively while solving common problems. We investigate the use of commitment by agents to proposed actions as a mechanism that allow agents to work concurrently on interdependent problems. Judicious use of commitment can not only increase the throughput of cooperative information systems, but also allow them to d...

In this paper, we compare the performances of cooperative and distributed spectrum sensing in wireless sensor networks. After introducing the basic problem, we describe two strategies: 1) a cooperative sensing strategy, which takes advantage of cooperation diversity gain to increase probability of detection and 2) a distributed sensing strategy, which by passing the results in an inter-node man...

In order to decrease fading and at the same time maintain an acceptable spectral efficiency, different cooperative schemes have been proposed for multi-source multi-relay networks. These schemes usually use the channel state information (CSI) at the transmitter side to do channel selection or relay selection to avoid deeply faded channels. A short note on the Distributed Coding Strategy, follow...

every society has its own culture, values, and ideology. translations convey the meaning as well as cultural and ideological values, beliefs, ideas and norms from source culture to target culture. one type of translation which nowadays is popular among people, and can attract so many audiences in different ages is audiovisual translation (avt), particularly dubbing. if there is difference betwe...

In this paper, we investigate the performance of introducing competition in cooperative coevolutionary algorithms to solve large-scale fully-separable continuous optimization problems. It may seem that solving large-scale fully-separable functions is trivial by means of problem decomposition. In principle, due to lack of variable interaction in fullyseparable problems, any decomposition is viab...
