One of the problems with exploitation of log trucks is damage to equipment during the process of transportation of wood material and during loading-unloading operations. The authors of the paper suggest equipping a log truck with an innovative protective butting device in order to increase reliability and work efficiency of the hydraulic manipulator. This device will allow aligning the sawn wood ends of wood products, and thus it will allow excluding a chance of protruding of sawn wood ends at an inadmissible scale which prevents forming a neighboring pack of wood products. The device will also allow excluding mechanical damages of a hydraulic manipulator by sawn wood ends of wood products being laid on a load platform. This will increase its reliability and will reduce the expenses on repair works.

There is developed a method for automating the process of finding reference lines and angles on the medical X-ray images. It is required to find the values of these characteristics between the distal femur and proximal tibia, for which task it is necessary to determine the joint line of each bone and anatomical line. The paper presents a scheme of the automated determining of boundaries of areas and constructing reference angles and lines. Automatic construction of the lines permits to estimate the state of the patient with the help of a number of known parameters characterizing angles. This makes it possible to significantly reduce the time spent on the analysis of the X-ray image, and make its estimate in the case when the radiologist cannot make the exact diagnosis. The created software product has demonstrated high efficiency of the proposed scheme of analysis.

An algorithm for the synthesis of the amplitude-phase distribution in quasi-circular antenna array for a given amplitude-phase radiation pattern is considered in the article. Selection of amplitude-phase radiation pattern as the set is due to the ability to use the most simple method of amplitude-phase synthesis of amplitude-phase radiation pattern. The predetermined amplitude-phase radiation pattern parameters (width of main lobe, level of side-lobes) are selected on the basis of physically realizable amplitude-phase pattern. The amplitude-phase radiation pattern may be formed using an circular or linear antenna. The solution is reduced to the formation of an overdetermined system of linear algebraic equations for the unknown complex amplitudes of the excitation currents in quasi-circular antenna array. The coefficients of the unknowns in the system of equations are amplitude-phase radiation pattern each of emitters for certain number of angular. The number of lines exceeds the number of emitters in a part of the antenna. The question of the possibility of saving the amplitude-phase radiation pattern parameters in the transition from the ring to the quasi-circular antenna array are discussed. Achieved mean square difference between the ring and the amplitude-phase distribution pattern quasi-circular antennas does not exceed 0,001.

The simulation of the magnetic field distribution in magnetic conductors of electrotechnical devices for the purpose of assessment of their characteristics in the operation modes is considered. The task has a form of the boundary value problem for the elliptic type equation in the ferromagnetic environment with nonlinear characteristics. We suggest using block elements in the form of arbitrary configured multipolar networks in the combination with nonlinear multangulars. The veber-ampere characteristics of the multipolar network are the result of a single solution of the boundary value problems for the multangulars forming block elements. The boundary value problems are solved using a complex finite element method, which provides direct solution for equations of constraints between magnetic strains and multipole fluxes. The nonlinearity of the characteristics is taken into account as a result of calculating the field distribution at the boundary of the multipoles by correcting the magnetic permeabilities of the block elements, which is performed iteratively.

At present, field programmable gate arrays are in high demand at design of automation and control devices. The basis of field programmable gate array logic element is the generator of functions of N variables, which is often called Look-up Table (LUT). LUT is based on a multiplexer and constructed as a tree of elementary multiplexers 2:1. LUT tuning is realizing by loading the constants to the inputs of static random access memory. At the article the simplest LUT with one variable is analyzed in detail. But the existing logical element has a deficiency. It is that M LUTs are required to implement M logic functions. In the CMOS transistors used in the LUT, drain nodes and sources are equivalent which allows reversing the signals. Based on this, there is proposed the LUT decoder (DC-LUT). A detailed description of the DC-LUT is provided at the article. The implementation of DC-LUT with a large number of variables is also considered. The proposed structure of DC-LUT allows implementing a system of logical functions that depend on conjunctions of a perfect disjunctive normal form more effective, in contrast with the existing solution.

This paper presents use metasystem approach to creation of complex system model. An opportunity to synthesize quantitative and qualitative models of separate subsystems in the form of a metamodel of complex system is distinctive feature of metasystem approach. Such approach gives the chance to develop and correct both the purposes of functioning of system, and a way of their achievement.

The results of the pilot survey conducted in late 2016 are presented. The purpose of the measurement was identifying deprivation of students as a characteristic indicator of political tension among the youth. The cognitive component of the perception of their relative deprivation was determined by direct survey. Using the obtained results the distribution function of these parameters according respondents was constructed. In the whole group it was received a fairly low declared level of deprivation. The sub-group with low and average level is 92% and only 8% of respondents noted the high level of this indicator. Interpretation of survey data was conducted using the early developed psychosemantic phenomenological stochastic model. In the model the relationship of level of emotional perception with the received data was determined stochastic integral-differential equation. It had a Monte Carlo in the multi-agent simulation package AnyLogic. In the end, the statistical characteristics such as the distribution function for affective perception of the relative deprivation according respondents were determined. In the whole group affective component is higher than the declared cognitive one. It is suggesting the need for assessments of deprivation using not only the cognitive measure, but also affective measure. In particular, the proportion of respondents with high deprivation according to this estimation higher than that obtained by direct survey and is 12%. This part of respondents is a subgroup of the risk opportunities for the development of the protest.
