The paper is devoted to improving the accuracy of determining the minimum resolvable temperature difference (MRTD) of thermal imagers by means of more sophisticated models of thermal images visual perception. An MRTD calculating algorithm, which is based on a more reliable approximation of the visual system modulation transfer function by Schultz, is considered. New expression for the bandwidth of Schultz's approximation, which does not depend on the angular size of the Foucault pattern bar, was obtained.

The new «scratch-tester» device for measurement of adhesion strength of coatings is presented. The device has a number of advantages as compared with known analogues – the expanded range of investigated sample sizes and more simple procedure of sample positioning, more precise measurement of scratching length, additional manner of registration of coating destruction or tearing off instant on the base of friction force. The device was used for investigation of Mo-Ti-N and Mo-Сu-N coatings on carbide cutting insert. It was found that Мо-Ti-N coatings have five times greater adhesion strength as compared with MoCu-N coatings.

There were investigated the capacity-voltage characteristics of the MOS transistors, fabricated by the similar process charts, with the identical applied technological materials), however at various time (appropriately further in the text series A and series B). It was shown, that the measurements of the capacityvoltage characteristics of the MOS structures make it possible to perform the quality diagnostics of the gate dielectric. The kind and shape of the measured characteristics are determined by the value of the additional positive charge in the dielectrics and density of the fast surface states on the Si-SiO2 interface, which correlate with the surface concentration of the technological impurities, adsorbed on the surface of the wafers in process of the devices fabrication, which makes it possible to make a conclusion about the quality of the applied materials and compliance of the manufacturing process. 

The method of thermally activated current spectroscopy was used for identification of two popular types of palm oils. The spectrum of thermally stimulated currents represents sufficiently intensive (up to 10-11 А) current peaks conditioned by differences in fatty-acid composition of oils. Introduction of representation on unstable associates, in which coordination bonds connect molecules of fat acid’s glycerides, allow interpret the experimental data about the current response at oil specimens heating. The current’s peaks location in a certain temperature range of TSC spectrum can be considered as an identify feature of investigated vegetable oils.
