This paper considers the stability of the fractional-order linear time-invariant systems with interval type uncertainties in both fractional orders and the relevant coefficients. It is an extension of our previous result on the robust stability analysis of the interval type uncertain fractional order LTI systems with crisply known fractional orders. We have proposed a stability check procedure for uncertain LTI systems with interval fractional orders and interval coefficients. The procedure is demonstrated with some simple examples

Feedback connection of (strict) passive systems with multiplicative disturbance on the input of one of systems is considered. Series of conditions are proposed, which provide (strict) passivity property for overall system. These conditions enlarge result from Hill, and Moylan (1977), where passivity property of such connection was established. Applications of proposed results to backstepping control and adaptive output control are investigated.

The theory of "codon-amino acid coevolution" was first proposed by Woese in 1967. It suggests that there is a stereochemical matching - that is, affinity - between amino acids and certain of the base triplet sequences that code for those amino acids. We have constructed a common periodic table of codons and amino acids, where the nucleic acid table showed perfect axial symmetry for codons and the corresponding amino acid table also displayed periodicity regarding the biochemical properties (charge and hydrophobicity) of the 20 amino acids and the position of the stop signals. The table indicates that the middle (2/sup nd/) amino acid in the codon has a prominent role in determining some of the structural features of the amino acids. The possibility that physical contact between codons and amino acids might exist was tested on restriction enzymes. Many recognition site-like sequences were found in the coding sequences of these enzymes and as many as 73 examples of codon-amino acid co-location were observed in the 7 known 3D structures (December 2003) of endonuclease-nucleic acid complexes. These results indicate that the smallest possible units of specific nucleic acid-protein interaction are indeed the stereochemically compatible codons and amino acids.

The paper is focused on the area of using multimedia in distributed systems (DS), its first part gives an introduction to the history of DS and multimedia. Its goal is to present basic terms and possibilities of implementation in this area where the big emphasis is given to integration and using multimedia and DS in still developing area of the internet. The report describes an experiment concerning on-line video transfer through the school network of VŠB-Ostrava where demonstrational projects have been developed (PC to PC, and connecting PC to the school network with various loads). These experiments were running using Microsoft and Real Network software, and the comparison of both systems has been done concerning the quality of the transfer.

Today many vendors covering the process control automation area offer a variety of products using a Linux operating system. These controllers, communication and visualisation resources meets customer requirements for easy and relatively low-cost integration with information systems for enterprise management, as they contain standardized communication and graphics components commonly used in the internet network. This article covers typical problems we meet when using Linux in control systems and gives typical examples of such devices.

This contribution describes improvement of soccer robot (class Mirosot) communication. 2.4 GHz band, half-duplex communication and more than 100 channels are some of several advantages of the system. Main advantage is wide range of communication modes and protocols which can be used on this hardware. It enables PC (Master) to robot, robot to robot communication as well as broadcast data for all robots. Main advantage is wide range of communication modes and protocols which can be used on this hardware. It enables PC (Master) to robot, robot to robot communication as well as broadcast data for all robots. This system (especial hardware part of system) rise effective bit-rate to order 100 kbit/s (before 19.2 kb/s), bi-directional communication and more channels for applying several channels in one time and safety communication protocol. Applications of distributed system, distributed AI as well as robot telemetry are now possible.

A new technique for correlated fault modelling in GTE redundant computer control systems is proposed. There are derived analytical expressions for the reliability evaluation and its Bayesian prediction. The developed model has been implemented in monitoring software, which generates the Bayesian predictive control charts and performs their neural network based analysis. The software has been carefully validated via a computer simulation and for real-life data.

In the last few decades many papers have written about the analysis of the infant cry. The acoustic analysis has a shorter history than emotional, physiological, etc. investigations. This paper deals with classical and new methods of acoustic analysis of the infant cry. The final goal is to detect hearing disorders according to the crying at the earliest possible moment. Classical acoustic methods were reproduced and compared with solutions, which were not available before. This paper most of all deals with the characteristics of the fundamental frequency of the cry in the time and in the frequency domain.

In order to support multimedia communication, it is necessary to develop routing algorithms that make decisions based on multiple Quality of Service (QoS) parameters. This is because new services such as video on demand and remote meeting systems have multiple QoS requirements. However, the problem of QoS routing is difficult because finding a feasible route with two independent path constraints is NP-complete problem. Also, QoS routing algorithms for broadband networks must be adaptive, flexible, and intelligent for efficient network management. In this paper, we propose a multi-purpose optimization method for QoS routing based on Genetic Algorithm (GA). The simulation results show that the proposed method has a good performance and therefore is a promising method for QoS routing.

The paper is devoted to the problem of modeling demand for inventory management of slow-moving items in the case of reporting errors. It is proposed a generalization of the beta-binomial demand model that takes into account possible reporting errors in the learning sample. For the new model, there are developed identification and forecasting algorithms that provide consistent estimators of the model parameters and mean square optimal forecasts. The efficiency of the proposed approach is illustrated by an application example for slow-moving car parts.
