This work describes some methods of controlling and planning the path for mobile robots on a area with disturbers. It refers about constants standing, and also about disturbers that are changing position.
The article presents the approach to use thermographic measurements to evaluate steam boiler's pipes degradation. A current process of measuring steam boiler's pipes thickness was shown. The problem of analysis and correction of thermographic images in order to acquire information about pipes' thickness was described.
Optimum choice location and type of switching devices related to increase safety and continuity power supply. Increasing usage of radio-controlled switching devices decrease time of break in MV networks crack up. This increases in their economics, as well as considerable decreases in cost.
The paper describes problem of feature selection. It refers to tumor cells recognition in bladder cancer. Two methods were presented. The first is analysis of the correlation matrix of attribute values and the second is example of the rough set theory.
In the paper, the Apriori algorithm implemented in Oracle Date Mining, has been used for searching association rules to fuzzy modelling of time series.
List of pretreatment process and picture analisys methods for mobile robots visual system. Recognition of objects undergoing distortion due to robot motion.
The energy-consumption of a pump-set depends on the efficiency of individual pumps however huge meaning has the way of steering and control of the whole set. The paper describes a control expert system for optimization of efficiency coefficient of a constant pressure inverter driven pump-set used in water supply.
The paper concerns information about growing needs for energy connected with renewable energy sources (RES). The paper concerns also a draft of the multienergy enterprise model. Computer implementation of that model could help in finance optimalization of the multienergy enterprise.
The paper describes economic methods which may be used for economic and financial analysis of technical solution of various schemes of distribution power networks.
The paper presents the analysis of eddy current brake. Power dissi-pated in the solid conductor (eddy currents losses) creates braking torque. The three dimensional finite element method was used in the analysis. Calculations for different rotor speeds and the power supply currents were carried out.
The paper presents the method of reconstruction of anatomical objects. Magnetic Resonance Imaging (MRI) is one of the most common imaging modalities in which internal body structure is viewed non-invasively. For rendering of MR images, we took an approach that was introduced by Cline in 1987 called the Marching Cubes 3D.
This article describes periodic research into the problem of electro-insulating oil. There is an overall description of the construction of optical sensors. An idea is proposed for using optical fibres and FC/PC mechanical connections in order to diagnose the age of the insulating liquid. Examples of the results of research are shown, which can form the basis for future research.
In the paper the performance of the modular reluctance motor (Transverse Flux Motor) with an outer rotor is presented. The calculation of the magnetic filed and electromagnetic torque were performed using Flux3d package based on the finite element method. The calculation results are in good agreement with experimental data obtained from the prototype motor. The calculations presented enable to determine...
The latest approach to the model order reduction and its previous achievements are considered in this paper. There is a comparison of most commonly used methods as well as a brief description of nonlinear model reduction via trajectory piecewise linearization.
In this paper author describes some ideas of speeding up a computer cluster used in a specific machine vision approach. He explains some ideas of minimization of communication time and other methods of speeding up the algorithm.
This article is regarding rational energy managment and influence of that for environment. It gives economic factors and law regulations forcing rational management of energy resources. It points out factors which have influence on rational energy management (investments, monitoring and managing), which causes reduction of energy usage. It unveils problem regarding to large, as well as small industries...
The light intensity and emitted light spectra of sonoluminescence depends mainly on the fluid and dissolved gases properties. These features indicate the possibility of estimating the amount of dissolved chemical compounds in liquids. The use of sonoluminescence for aging properties diagnostic of insulation oils was proposed.
This paper reviews fundamental problems of constrained optimization and generally describes methods for linear and nonlinear constrained optimization. A job scheduling example of nonlinear integer constrained optimization is shown to illustrate the considerations.
The paper presents possibilities of communication and theoretical analysis of communication problems for two-level cluster architecture. It describes also a typical architecture of cluster computer and how to make use of it to improve the performance of parallel algorithms, basis of simple Hockney's model.
The paper shows that on the basic of current spectroanalysis the quality of squirrel cage of induction motor can be established. Later the use of such a spectrum was suggested for training data for artificial neural network. Neural network, in the study process is able to detect damages in squirrel cage.
