    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (148 KB) | HTML iconHTML

    Fuzzy defuzzification is one of the most important part of the fuzzy control. Several approaches exist. Mamdani uses the a-cuts and builds the union of the membership function. The resulted function is the starting point of the defuzzification process. In this article we define more natural way to get the membership function by using fuzzy arithmetics. The defuzzification is the optimum value of t... View full abstract»

    Summary form only given. Intelligent cooperation of agents/entities in autonomous robotics is a new and very exiting research field. If one plans/implements a cooperating robot system with intelligent behavior, not all scenarios appearing in the "life of robots" can be programmed in advance and thus effective, fast and compact communication is one of the most important cornerstones of the high-end...

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (101 KB)

    I have already proposed a paraconsistent annotated logic program called Extended Vector Annotated Logic Program with Strong Negation (EVALPSN), which can deal with conflict resolving and defensible deontic reasoning. These EVALPSN reasoning functions have been applied to various intelligent control and safety verification systems such as pipeline valve control, traffic signal control, railway inte...

    60 years ago the American mathematician and electrical engineer Claude Elwood Shannon (1916-2001) published "A Mathematical Theory of Communication" and nobody could survey this theory's enormous consequences for science and technology. Shannon's article appeared in two parts in the July and October 1948 editions of the Bell System Technical Journal. However, it is very probable that this article ... View full abstract»

    Publication Year: 2009, Page(s):11 - 12
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (49 KB)

    Summary form only given. Optimization problems arise in a wide variety of scientific and engineering applications. It is computationally challenging when optimization procedures have to be performed in real time to optimize the performance of dynamical systems. For such applications, classical optimization techniques may not be competent due to the problem dimensionality and stringent requirement ... View full abstract»

  • Probabilistic model for a distributed feature selection method

    Publication Year: 2009, Page(s):27 - 32
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (233 KB) | HTML iconHTML

    When building topic based document classifiers, feature selection is a key step: features not holding any information about the topic of a document introduce only unnecessary noise during the classification. In a distributed environment, when the nodes are interacting, the locally retrieved features and the their attributes must be shared to have at every node a more accurate estimation of the glo...

    The increasing sophistication of computer programs and communication systems requires the development of more efficient and interactive human-computer interfaces. One solution to this problem could be the brain-machine interfaces. The aim of this paper is to explore the possibilities of using context dependent interpretations of EEG signals, in addition to signal processing techniques. View full abstract»

    Cellular automata (CA) are used to simulate a various number of complex processes, based on simple rules applied to a large population of cells. Wear of turbine blades is also a very complex process which is analyzed in most cases using empirical data. The model described in this paper uses cellular automata obeying a set of rules and using values of initial state parameters which were computed by... View full abstract»

    The problem of identifying cosmic gamma ray events out of charged cosmic ray background in Cherenkov telescopes is one of the key problems in very high energy gamma ray astronomy. Separation between gamma-like and hadron-like events is performed by a Bayesian ensemble of neural networks and Markov chain Monte Carlo methods for model parameters optimization. The results are discussed in terms of th... View full abstract»

    The present work approaches some important issues from image processing such as object recognition and distance estimations of different objects from the environment. As we know image processing deals with endowing computers with visual functions. Until now the capabilities of similar systems were limited to object recognition and to avoid obstacles. We have tried to combine those two capabilities... View full abstract»

    Safety is a major concern in many complex robotized systems especially when the task implies collaboration between human and robot with the workspace sharing. In this research a theoretical representation of the integrated safety monitoring system is introduced. The monitoring system is modeled as a separated unit which decision making mechanism is based on the safety expert system (SES) data anal... View full abstract»

    The paper discusses a new hybrid method in sound diarization (the process of segmenting an audio file into chunks that represent unique sources and clustering the obtained segments into groups that represent the same item). The most recent results are focusing mainly on the identification of voices during the telephonic recordings. In the hybrid method proposed here, a clustering is applied first,...

    This paper addresses robust adaptive sliding mode control for MIMO nonlinear systems in the presence of uncertainties and external disturbances. To achieve stability and performance, we propose a sliding mode control scheme with the design of a gain, whose gain is not constant and need to be adaptively updated. Unlike some existing methods for sliding mode control, no knowledge on the bound of unc... View full abstract»

    The interpolative control structures, in fuzzy or other variants, don't achieve very good performances when the controlled plant contains dead times. In an interpolative adaptive controller is presented, named PSAIC, which for certain types of plants offers good performances regarding variations of the plant's parameters, and particulary for some small variations of the dead time.
