    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (641 KB) | HTML iconHTML

    Preference modelling is a fundamental part of several applied fields but at the same time it has its own interesting theoretical problems. There exists a well-known axiomatic approach to fuzzy preference structures. In this axiomatic framework, general constructions of strict preference, indifference and incomparability relations associated with a fuzzy large preference relation are established vi...

    The paper introduces neuro-fuzzy modeling to the problem of controlling interstate conflict. It is shown that a neuro-fuzzy model achieves a prediction accuracy similar to Bayesian trained neural networks. It is further illustrated that a neuro-fuzzy model can be used in a genetic algorithm (GA) based control scheme to avoid 100% of the detected conflict cases. The neuro-fuzzy model is then sugges...

  • A Model for Target Ranging in Shallow Water and Short Ranges

    Publication Year: 2006, Page(s):49 - 52
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2722 KB) | HTML iconHTML

    Measuring the target range (ranging) in shallow water and at short distance is always affected by two factors namely reflection and refraction at the surface and bottom. Also since the maximum range is low, the loss is not significant. Therefore, received amplitude of multipath is high and comparable to the received wave in the direct way. Moreover, due to low bit angle of the surface and bottom r... View full abstract»

  • Extending an OCL Compiler for Metamodeling and Model Transformation Systems: Unifying the Twofold Functionality

    Publication Year: 2006, Page(s):57 - 62
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (7045 KB) | HTML iconHTML

    Object constraint language (OCL) is used to extend the capabilities of Unified Modeling Language (UML) diagrams by defining constraints for the model items. Since OCL is based on, but not limited to UML diagrams, it can be used in generic metamodeling environments to validate the models as well. Also, OCL can be used in model transformation systems to specify additional constraints for the transfo... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (452 KB) | HTML iconHTML

    AC induction motors become very popular for motion control applications due to their simple and reliable construction. There are applications in which speed sensors should be omitted, to achieve cost reduction. In such a situation, we have to solve the task of state reconstruction only from voltage and currents measurements - design so called sensorless control algorithm. In the current paper, we ...

    Ontologies are today widely used in many different domains with the goal to clarify them and, with the development of semantic Web, to make them available across the Internet community. The legal domain has also been explored concerning ontologies, both on the general as on the sub-domain level. In this paper are explored problems of formal ontology development regarding areas in specific legislat... View full abstract»

    This paper presents an online time scaling concept for robotic manipulators. The task is to ensure the fastest possible motion along a trajectory with a given geometry in the robot workspace. The other requirement is tracking accuracy. Robots should move not only with high speed but with high precision as well. The speed of the motion cannot be arbitrary fast. It is delimited by the saturation of ... View full abstract»

    This paper presents novel algorithm for stator resistance identification. This algorithm operates online and requires no external excitation. The identification is realized from steady state operation. This partially limits the employment of proposed algorithm for drives which are designed to run mostly in steady state, it means for the applications where the load changes mostly slowly.

    Car body deformation modeling plays a very important role in crash accident analyses, as well as in safe car body design. The determination of the energy absorbed by the deformation and the corresponding energy equivalent speed can be of key importance, however their precise determination is a very difficult task. Although, using the results of crash tests, intelligent and soft methods offer an au... View full abstract»

    The basic question of our study is to present a possible model for handling uncertain information. This model is worked out in the framework of DATALOG. The concept of fuzzy knowledge-base is defined as a quadruple of any background knowledge; a deduction mechanism; a connecting algorithm, and a decoding set of the program, which help us to determine the uncertainty level of the results. We also s... View full abstract»

  • A Method to Represent Restricted Classes of Planar Graphs in the Enhanced Spatial Relational Model PLA, Based on Hahn Graphs

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (464 KB) | HTML iconHTML

    In this paper we enhance the PLA relational spatial model for storing a special type of planar graphs. The PLA-model is very handy to store 2-connected planar graphs, but it is not capable at all to store some other important classes of planar graphs: trees and, more generally, planar graphs with cut edges. In this paper we propose a method for their representation. The main idea is based on Halin... View full abstract»

    In this paper detailed dynamic analysis of a quantitative mathematical model of a polymerization process is presented. The process serves as an appropriate paradigm of multi-variable dynamic systems of strong non-linear coupling in the control of which the state propagation of various internal degrees of freedom cannot directly be controlled: the desired output is nonlinear function of these quant...

    In the early seventies, it was clear that primary amino acid sequence and its local solution environment hold most of the information necessary for protein folding. Since then, scientists have been trying to solve the bioinformatics problem by constructing the tertiary three-dimensional structure of protein from the primary amino acid sequences by using computational biology.
