This paper presents a dynamic voltage and frequency scaling methodology for long-term operation, using fault-tolerance to prevent failures. The DVFS methodology allows a dual-mode operation, targeting high performance or low-power operation modes, and using an on-line circuit monitoring with aging-aware fault-tolerance to prevent errors during a long-term operation. Fail-safe operation is achie...

This paper describes and illustrates the optimization of a safe mobile robot control process in collision situations using model multistep matrix game many participants form dual linear programming problem. The synthesis non-cooperative cooperative software was performed Matlab/Simulink to determine path when passing greater number other robots obstacles. operation motion algorithm is illustrat...

Measurements of the fast and precise movements of the eye-critical to many vision, oculomotor, and animal behavior studies-can be made non-invasively by video oculography. The protocol here describes the construction and operation of a research-grade video oculography system with ~0.1° precision over the full typical viewing range at over 450 Hz with tight synchronization with stimulus onset. T...

This paper presents an image-based cooperative driving system for telepresence robot, which allows safe operation in indoor environments and is meant to minimize the burden on novice users operating the robot. The paper focuses on one emerging telepresence robot, namely, mobile remote presence systems for social interaction. Such systems brings new opportunities for applications in healthcare a...

By performing the encoding operation on several message packets, rateless coding in cooperative networks has the potential risk of processing information already available to the receivers. In this paper, the intermediate packet decodability of rateless codes is exploited to mitigate such redundant packet processing at the cooperating nodes. The message packets that are already decoded at the r...

We discuss the impact of the separation of logic engines (independent logic processing units) and multi-threading on the design of coordination mechanisms for a Prolog based agent infrastructure. We advocate a combination of coroutining constructs with focus on expressiveness and a simplified, multi-threading API that ensures optimal use available parallelism. In this context, native multi-thre...

The maintenance became one of the strategic industrial functions. Far from being stabilized today, it progress by introducing the new management methods and the technological development of the production equipments, in particular in the measurement and the control operation. All these factors modify the organization modes of the maintenance function, which converges more and more towards a coo...

Relay assisted cooperative wireless communication has been shown to have significant performance gains over the legacy direct transmission scheme for Ad-hoc network. An efficient cooperative Medium Access Control Scheme (MAC) is needed to solve the difficulties induced by relaying and cooperative computing. Another challenging issue is the extension of network lifetime of an Ad-hoc network with...

PROFESSOR JEAN LEMAIRE: The two models I am going to present originate from game theory. They were devised as illustrations of game theoretical 'models to my operation research students. Game theory has not yet reached a point where it could be practically implemented in insurance companies. The first model I am going to describe is non-cooperative game theory. The second one uses utility theor...

We introduce a cooperative co{evolutionary system to facilitate the development of teams of heterogeneous agents. We believe that k different behavioral strategies for controlling the actions of a group of k agents can combine to form a cooperation strategy which eeciently achieves global goals. We both examine the on{line adaption of be-havioral strategies utilizing genetic programming and dem...
