A theoretical study of the quality and the validity range of different numerical and analytical methods of calculating of the frequency shift in measurement using microcromechanical sensor is presented. This work considered a calculating method for natural frequency in comparison with experimentally measured oscillation frequencies of microcromechanical sensor immersed in air and/or viscous medium. The numerical methods for solving the equation of resonance oscillation of the console fixed on one side are considered for calculating the natural oscillation frequencies of standard AFM cantilevers.

A novel numerical model is proposed for modelling two-dimensional planar gas flows in granular phase change material (PCM). The mentioned model consists of system of equations based on the classical methods of mechanics of heterogeneous media which is solved by original finite-difference algorithm. Effect of heat transfer with ambient medium on mushy zone propagation in the bed of granular PCM is investigated by means of numerical experiment. It is shown that phase transition speed can decrease significantly near the side walls of the bed in relation to the central region which provides curvature of the mushy zone boundaries and nonuniform melting of the PCM in the bed. Kind of curvature of these boundaries can change in dependence of heat conductivity coefficient of the PCM.

The problem of evaluating soft sensors for plants with irregular output measurement time is considered. In order to find the relationship between inputs and output, the wavelet-transformed inputs are integrated into the regression model framework. A suitable procedure for wavelet type selection is discussed. An example is provided to illustrate successful application of the proposed approach and an industrial case study is given for soft sensor evaluation of a reactive distillation process.

The recently found (Tl,Au)/Si(100)c(2×2) two-dimensional compound which possesses spin-split surface states with peculiar spin texture and strong band anisotropy was examined using low-temperature scanning tunneling microscopy and scanning tunneling spectroscopy observations and in situ four-probe transport measurements. Two types of the one-dimensional incommensurate Friedel oscillations were found to develop near the surface defects with the wavelengths corresponding to the nesting vectors of the (Tl,Au)/Si(100)c(2×2) Fermi surface. In transport measurements, samples show strong localization behavior when density of defects is sufficiently high. With low density of defects, the system demonstrates a metallic behavior with fingerprints of superconducting transition at estimated Tc=1.33K. Thus, the (Tl,Au)/Si(100)c(2×2) system hosts a combination of fascinating properties and effects, including one-dimensional Friedel oscillations, superconductivity, and a spin-split anisotropic Fermi surface, that opens an avenue for prospective investigations of the interplay of collective electronic phenomena in atomic layer material.
