  • Polyphase Order Analysis Based on Convolutional Approach 

    Drutarovsky, M. (Společnost pro radioelektronické inženýrství, 1999-06)
    The condition of rotating machines can be determined by measuring of periodic frequency components in the vibration signal which are directly related to the (typically changing) rotational speed. Classical spectrum analysis ...
  • Interactive Progressive Image Transmission 

    Matus, E.; Levicky, D. (Společnost pro radioelektronické inženýrství, 1999-06)
    In progressive image transmission (PIT) the image is transmitted progressively i.e. the low detail image is transmitted as first followed by transmission of detail signals. In our contribution we consider interactivity in ...
  • The State Space Mystery with Negative Load in Multiple-Valued Logic 

    Galajda, P.; Guzan, M.; Spany, V. (Společnost pro radioelektronické inženýrství, 1999-06)
    Switching sequential circuits are an indispensable part of many modern electronic devices, such as memory cells, flip-flop sensors, and many others. Since the invention of flip-flop switching circuits, the study of their ...
  • Motion Analysis Based on Invertible Rapid Transform 

    Gamec, J.; Turan, J. (Společnost pro radioelektronické inženýrství, 1999-06)
    This paper presents the results of a study on the use of invertible rapid transform (IRT) for the motion estimation in a sequence of images. Motion estimation algorithms based on the analysis of the matrix of states (produced ...
  • Time-Frequency Analysis of Signals Generated by Rotating Machines 

    Kocur, D.; Zetik, R. (Společnost pro radioelektronické inženýrství, 1999-06)
    This contribution is devoted to the higher order time-frequency analyses of signals. Firstly, time-frequency representations of higher order (TFRHO) are defined. Then L-Wigner distribution (LWD) is given as a special case ...
  • Fuzzy Stack Filters for Image Processing 

    Marchevsky, S.; Stupak, Cs. (Společnost pro radioelektronické inženýrství, 1999-06)
    This paper is oriented to filtering by fuzzy stack filter of monochromatic images distorted with impulsive noise. Fuzzy stack filter is acquired by extension of stack filters by means of fuzzy logic. Adding some parameters ...
  • An Educational Application of Distributed Measurement Systems 

    Michaeli, L.; Saliga, J. (Společnost pro radioelektronické inženýrství, 1999-06)
    This paper describes an educational application of distributed measurement systems for the tutored and self-educational process that has been designed and applied at the Department of Electronics and Multimedial ...
  • Medium Access Control Protocols for Wireless ATM 

    Dobos, L.; Juhar, J.; Cizmar, A. (Společnost pro radioelektronické inženýrství, 1999-06)
    The most crucial issues in the conception of an efficient wireless ATM network are the design of the physical layer, data link layer. Medium Access Control (MAC) protocol and mobility management functions. In this article ...
