Spectral characteristics of the recorded vibration signals are then analyzed statistically, and compared visually and numerically. In the paper the set of representative parameters for a comprehensive assessment of the surface texture status after slide burnishing has been proposed.
Short-circuit current represents a danger for the kocurrk of the power transformer. Then, the results are classified by the Self-Organizing Map method in order to create different levels of safety or danger concerning the magnetic field to which tablet computer users are exposed.

It was caused by degradation of the image contrast by scattered radiation. In the vacuum thermoforming process, the product deviations depend on several parameters of the system, which make the analysis, the computational modeling, and the optimization of errors a multi-variable process with conflicting objectives. However, the crowns of teeth are not visible in standard MRI scans. The concrete, however, exhibits such characteristics only on the condition that the steel fibers in the final, hardened composite have been distributed evenly.

By means of the statistical simulation methods, the practical interference immunity of the introduced demodulator, together with the influence of phase locking errors have been tested. We have developed an optoelectronic sensor system to determine the mass of deposited dust and the resuspension rate. Low-field MR scanners, usually with an open design, are suitable for claustrophobic and obese patients, as well as for children, who may be fearful in closed MR scanners.
