The permanent increasing of quality standards, world wide competition, as well as the legislation of regulation of the product responsibility, require not only a proper documentation of the measurement data of the production, but also the continuous supervision of measuring and test equipment. Especially in modern flexible and intelligent production environment, measuring devices are often connected directly with the manufacturing process. This causes direct or indirect influences on the quality level, therefore the supervision and management of measuring and test equipment is becoming a significant part of the quality management for the entire production.
The supervision of measuring equipment is an essential quality requirement for modern production especially at the higher demands of micro and nanotechnology. The efficiency of the confirmation can be increased and expenses can be reduced substantially through computer assistance with flexible checking intervals. A special method developed for this purpose allows increasing of the flexibility level and efficiency of a system for the intelligent management and supervision of measuring devices.

In this paper, a task-specific measuring capability criterion is described, applicable to select or validate measurement systems that provide data to set the process aim, when the techniques known as "sequence of values" or "difference chart" are used. The criterion is based on the estimation of the "uncertainty of the process mean", which characterizes the dispersion of the values that could reasonably be attributed to the process mean after the setting procedure. The proposed criterion is compared with the discrimination ratio and with the uncertainty per tolerance ratio, showing that the last one fails to predict the measuring capability for aim-setting operations.

Products with cylindrical surfaces are manufactured in many (e.g. paper, chemical, steel, heating or shipping) industries. It is required that regular estimations of cylindricity profiles be made during the production process. The reference methods can be used for measurement of cylindricity. The cylindricity deviation includes the roundness deviation in different cross-sections of an object, the relative change of its diameter and the noncentricity of profiles in relation to the nominal axis of the object. The reference measurement systems applied nowadays enable measurement of roundness profiles in relation to fixed points of support in different cross-sections of the measured object. Furthermore, it is possible to evaluate the relative difference of the diameters. However, in traditional reference measurement systems there is no possibility of measurement of the non-concentricity of profiles. That is why appropriate reference systems for measurement of cylindricity have had to be developed.

Stents and stentgrafts are used in last years very often, especially for treatment of stenosis and aneurisma of vessels. But there are some possible risks, when stents are applicated. The stent can migrate inside a vessel, it can be leaky or deformed.
To investigate interaction between stent and a wall of vessel we must have model of mechanical properties of the vessel and of the stent. As to the vessels a lot of models were designed but as to the stents, the situation is worse. So we have decided to try to develop our own model based on the knowledge of material parameters of nitinol, of the geometry of stent and of its segments.

Abstract – The effects of extremely low-frequency (ELF) electromagnetic fields (EMFs) on human beings, animals and plants have been the subject of debate and research for the last thirty years. The ELF EMFs are produced by power transmission and distribution lines and household appliances. The last ten years have also seen the wide use of mobile phones all around the world. The base stations that are needed for mobile communication have sprung all over the cities and neighborhood. They operate on the frequencies from 400 MHz to 1900 MHz. The instrumentation for generation of EMFs of both power frequency of 50 Hz and mobile phone frequencies are discussed in this paper. The instrumentation is used for experiments to learn how EMFs are affecting the plant physiology.
