    The main motto of rough sets is: "Let the data speak for themselves!". Rough sets are based on the theory of sets. The main applications of rough set theory are attribute reduction, rule generation and prediction. Many examples of applications of rough sets to process control, economics, medical diagnosis, biochemistry, environmental science, biology, chemistry psychology, conflict analysis and ot...

    Standard methodology for analysis of air pollution epidemiological time series expresses effects in terms of relative risk, i.e. increases in the number of events associated with a short term increase in air pollution. However, even large relative mortality rates may in fact reflect a very small effect in terms of person-years life loss. In Zagreb, mortality in 1995-1997 was significantly associat...

    We propose an end-to-end congestion control and bandwidth estimation algorithm for ABR traffic in high-speed ATM networks. The congestion control algorithm is derived using the Smith predictor and uses an estimation of the bottleneck queue level as feedback. The estimation allows the algorithm to be executed at the entry node of a high-speed ATM network without requiring any explicit feedback from... View full abstract»

    Flowshop scheduling deals with determining the optimum sequence of jobs to be processed on several machines so as to satisfy some scheduling criterion. It is NP-complete. Heuristic algorithms use problem-specific information to yield a good working solution. Genetic algorithms are stochastic, adaptive, general-purpose search heuristics based on concepts of natural evolution. We have developed a ne... View full abstract»

  • General object-oriented framework for iterative optimization algorithms

    Publication Year: 2001, Page(s):379 - 384 vol.1
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (424 KB) | HTML iconHTML

    It is usually impossible to exactly solve hard optimization problems. One is thus directed to iterative algorithms. In the implementation of these iterative algorithms, some common characteristics can be observed, which can be generalized in an object-oriented framework. This can significantly reduce the time needed for implementation of an iterative algorithm. This paper presents a class hierarch... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (660 KB) | HTML iconHTML

    VRML is one of the most popular languages for building virtual worlds, but it lacks support for the reception of streaming data. In our work this functionality was added by embedding a small Java application into the virtual environment. The application controls the transmission of streaming content (audio or video) from the content provider into the virtual world, real-time communication between ... View full abstract»

    An important problem in discriminant analysis that has received little attention in the literature, is the effect of outliers when variable selection is the first step in the analysis. We consider two methods of dealing with this problem: the classification performance of these methods, and the classification performance if possible outliers are ignored, are compared in a simulation study.

    Shows two methods for achieving organizational results. If an organization focuses only on the strategic side of the model, and if there is little congruence between the strategic and cultural side, the organization will stagnate and develop the characteristics of an entrenched bureaucracy. In contrast, if a company focuses only on the cultural side, the organization will quickly become a wonderfu... View full abstract»
