In this paper, the geosteering technology of drilling tool, relatively bottom of oil horizon in oil and gas reservoir was proposed. A theoretical model of borehole logging tool, transmitting and receiving ultra-wideband (UWB) electromagnetic pulses was proposed. The pulsed voltage at the output of the receiving antenna of borehole electromagnetic logging tool (BELT), located near the oil-water contact (OWC) was simulated, used experimentally tasted models of complex dielectric permittivity (CDP) of oil-saturated rock. The principal possibility of detecting the reflected pulse from transition layer which separates the oil-saturated rock from water-saturated rock and determine the distance to OWC was shown.

In this paper, we propose a subspace algorithm for the identification of linear-time-invariant discrete-time systems with more outputs than inputs from measured power spectrum data. The proposed identification algorithm is interpolatory and strongly consistent when the corruptions in the spectrum measurements have a bounded covariance function. Asymptotic performance of the proposed algorithm is illustrated by means of a numerical example.

Due to the randomness of the biochemical process at the molecular level, genetic regulatory networks are inherently noisy. They are also subjected to extrinsic noises which are external to the gene expression. In this paper, we consider genetic regulatory networks with non-vanishing additive noises and investigate stochastic asymptotic boundedness of them. By using itô's differential formula and Lyapunov-Krasovskii functional, we derive sufficient conditions so that system solution be bounded (in expectation) by a monotone function of the supremum of the covariance of the noise. All these conditions are presented in terms of linear matrix inequalities (LMIs). Finally, Numerical example illustrates the usefulness and applicability of the proposed conditions.

Thin films of gallium oxide have been deposited in vacuum on the GaAs substrates by thermal evaporation of powder Ga2O3. The capacity-voltage and siemens-voltage characteristic of Ga2O3-GaAs structures were investigated. It was shown that the greater the action time of high-temperature treatment in the flow of inactive gas (Ar), the lower the capacitance of the dielectric and thus lower permittivity (ε) of Ga2O3. This phenomenon can be explained by the change structure of Ga2O3 and its reconfiguration in the more conductive phase with a small quantity of the dielectric constant. The amount of surface-states density at the interface of annealed MOS structures decreases to 1·1012 cm−2 eV−1.

Arc antenna arrays for high frequency band are examined. The optimal length of log-periodic array elements is discussed. The expression for array dimensions are derived which ensure constant beam width within frequency range. It is shown by means of computational modeling that for keeping of constant beam width the length of element should be extended.

The work "Modeling and Simulation of Optimal Control Systems for Education and Training" discusses the investigation of the process of optimal control in real time with mathematical methods, their realization with modern systems of mathematical modeling and computer visualization of the results in multimedia form. An example when aircraft lunar landing at first by parabola and then vertically to the Moon surface is considered. The work presents the existing works, the design and determination of orientation and stabilization of which happen with aircraft flight characteristics. The simulation of aircraft motion becomes possible by means of special computer software. It is seen that the visualization of optimal and extreme problems of control in real time is the most complicate process from the considered investigation.
