This paper is proposing a new approach of the RMT (Reconfigurable Machine Tool) programming. The approach is based on a new control architecture characterized by high level of reconfigurability. The programming consists in the building of two documents: i) machineprogram, concerning machine reconfiguration phase and ii) part-program, concerning the programming of the machine to process a specif...

Past applications of artificial intelligence techniques to shop floor control tasks arc reviewed. In the area of resource allocation in distributed manufacturing D’stems, the issue of resource reconfiguration is identified as a neglected problem. A game theoretic planning model suitable for use in a distributed shop floor control environment is introduced. Autonomous machine controllers consult...

This research paper deals with reconfigurable discrete-event control systems which are distributed on networked devices to execute control software tasks with shared resources. A reconfiguration scenario is also assumed to be any addition, removal or update of tasks and shared resources. Nevertheless, the addition of resources at run-time can bring the system to a blocking problem that is somet...

State estimation is used in power systems to estimate grid variables based on meter measurements. Unfortunately, power grids are vulnerable to cyber-attacks. Reducing cyber-attacks against state estimation is necessary to ensure power system safe and reliable operation. False data injection (FDI) is a type of cyber-attack that tampers with measurements. This paper proposes network reconfigurati...

We demonstrate how simple local sensing and control rules achieve useful emergent behaviors in modular self-reconfigurable (metamorphic) robots. Our biologically inspired approach grows structures with the desired functionality even though the final shapes have some unspecified, random variation. By contrast, other self-reconfiguration algorithms require an a-priori exact description of a targe...

This project presents two original implementations of improved accuracy current-mode multiplier and divider circuits. Besides the advantage of their simplicity, these original multiplier and divider structures present the advantage of very small linearity errors that can be obtained as a result of the proposed design techniques (0.9% and 0.75%, respectively, for an extended range of the input c...

in this paper, a multi-objective reconfiguration problem has been solved simultaneously by a modified ant colony optimization algorithm. two objective functions, real power loss and energy not supplied index (ens), were utilized. multi-objective modified ant colony optimization algorithm has been generated by adding non-dominated sorting technique and changing the pheromone updating rule of ori...

In this study we present an experiment investigating the reconfiguration process elicited by the task switching paradigm in synaesthesia. We study the time course of the operations involved in the activation of photisms. In the experimental Group, four digit-color synaesthetes alternated between an odd-even task and a color task (to indicate the photism elicited by each digit). In both tasks, t...

Abstract: In this paper a method for fault tolerant control in dynamic systems is presented. In an integrated design, the proposed approach is composed of two stages. The first step is the detection and isolation of the failed component while the second step is represented by the reconfiguration mechanism. It consists in the estimation of new control parameters after evaluation of the performan...

Abstract In this paper we present optical communication multibus system including: physical topology, logical topology, structure of central control unit (CCU). We describe the task of CCU: analyze the state of logical buses, topology reconfiguration, system structures clustering, unexpected events handling, statistic gathering, etc. In this paper we present synthesis of core system network bas...
