A nonlinear-noise filtering method for image processing, based on the entropy concept is developed and compared to the well-known median filter and to the center weighted median filter (CWM). The performance of the proposed method is evaluated through subjective and objective criteria. It is shown that this method performs better than the classical median(More)
Designing an effective criterion and learning algorithm for find the best structure is a major problem in the control design process. In this paper, the fuzzy optimal control methodology is applied to the design of the feedback loops of an Exothermic Continuous Stirred Tank Reactor system. The objective of design process is to find an optimal(More)
As the choice of the communications protocol for a given application represents one of the most significant tasks in the development of information technical solutions, this article focuses on the high level open protocol of SCADA systems: PUR 2.4, as well as its implementation and the design of a RTU TESTER and the conception of a RTU.
