In is paper investigated and confirmed the Deposit of bentonite clay on the studied road section of Osh-Isfana. Osh-Isfana road is an international meaning road. The road is located in the Nookatsky district of Osh region of Kyrgyz Republic and connects the two regions and gives access to the territory of neighboring States – Tajikistan and Uzbekistan. Overestimation of the roadbed with moisture is an extremely dangerous phenomenon, since the strength of the pavement and the stability of the slopes of the mounds and excavations are greatly reduced. When designing the basis of the road on collapsible soils are equally important inside the event with the aim of reducing the likelihood of soaking the soil. The recommendations on the use of local building material as a waterproofing layer of the road structure, interrupting the movement of moisture, while ensuring the removal of water from rain and snow melt.

Based on the results of theoretical and experimental studies at FGBAC FNAC VIM, we conducted a system analysis of the existing gravitational grain cleaning machines and developed a prototype of a gravity-pneumatic seed-seeding machine (VIM-3). His laboratory (preliminary) tests were carried out. The general view, constructive and techno logical scheme of the machine are presented. The prototype of a cleaning machine can purify wheat seeds up to 99.5% by feeding the processed material up to 2.5 t / h with an impurity content of more than 80%, which corresponds to the category of OS and ES of GOST R 52325-2005, as well as to international norms .

In this paper we consider the problem of constructing a precise passability model by point cloud obtained from stereo cameras. To solve this problem, we used a hierarchical elevation map. The criterion for dividing cells into smaller ones was extended to take into account the cell's completeness with a limited field of view. The passability model was also supplemented with an algorithm for detecting step obstacles. The accuracy and completeness of the detection of obstacles and a free surface was calculated experimentally on dataset taken in real conditions. The result of the experiment shows that the proposed approach increases the number of detected obstacles without significant loss of accuracy.

The article describes the chemical composition of groundwater in the Rostov area. On the basis of sanitary and environmental assessment of the chemical composition of groundwater from wells, one of the areas of the South-Eastern part of the Rostov area, which are sources of water of the Egorlykskaya station, it was found that the concentration of hydrogen sulfide exceeds the MPC by about 1000 times. Analysis of methods of water purification from hydrogen sulfide, the main of which include: oxidation with molecular chlorine, sodium hypochlorite, hydrogen peroxide, showed the advantage of using the hydrogen peroxide. A new reactor design is proposed, which allows to increase the contact time of the treated water with the oxidant by hydrogen peroxide without increasing the size of the structure. This allows the maximum transfer of dissolved hydrogen sulfide in the solid phase.

The complexity and high cost of multiplexing optical fiber sensors is still the main limitation for the widespread introduction of sensory systems, both distributed and quasi-distributed, and point-like. The article proposes a new multiplexing method that takes advantage of both broadband and two-frequency radio-photon multiplexing systems. The simplest broadband radiator is taken from the first, but a complicated and expensive system of spectrometry is not used to determine the central wavelength of fiber Bragg gratings. From the second, a recording system is used at the beat frequency between two components, but an expensive system for generating two- and polyharmonic probing systems is not used. The multiplexing parameter is determined by the frequency of separation between the transparency windows of a fiber Bragg grating, for example, with two phase π-shifts, which differs by a certain value for each of the sensors. The mechanism of modeling of gratings of the specified type is given, in principle the possibility of multiplexing of various number of sensors is shown. When using sensor networks built on the basis of passive optical, the number of multiplexed sensors can reach 256, with all sensors having the same Bragg wave of the wave, and can be combined into tree, bus and other topologies.

Theoretical studies of the temperature distribution during laser heating of the TiO2 precursor film on the FTO/glass substrate have been carried out. The simulation was performed on the basis of a numerical solution of the heat equation in the Matlab program to determine the energy density of the laser radiation necessary for crystallization of TiO2. It was shown that on the surface of the TiO2 precursor the temperature reaches a maximum value at a time point of 133 ns with the Gaussian temporal form of the laser pulse. The optimum energy density for crystallization of the TiO2 precursor film with the nanosecond pulse duration is 1.3-1.6 J/cm2, when the film thickness temperature corresponds to 400-500 °C. The obtained results of the simulation are consistent with experimental studies.

The article considers the aspects of parametric modeling, his key features, and the question of the relevance of this direction in the design of unique buildings and structures. Are presented surfaces that have not yet acquired the mass character of design and erection, or have not been built anywhere else, but have a high potential to become in the future a great adornment of urban development. In construction, a very limited number of thin-walled structures are used: cylindrical, spherical, shallow transfer shells, conical, shells of rotation. This is only a small fraction of the existing variety of geometric shapes developed by geometers, so the parametric architecture has a great potential for application. The finite element method allows modeling objects of a parametric architecture, approximating buildings and structures with rod, plate and shell elements. The parametric architecture expands the scope of the finite element method and allows the creation of unique high-altitude and long-span buildings and structures. However, the finite element library of the software complex requires modernization and expansion to design unique surfaces of the parametric architecture.

In the paper, we give a brief overview of the main developments made personally and under the direct supervision of the professor, academician RANS andIAELPS P. Kudryavtsev. These developments are devoted to the use of sol-gel processes in various branches of science and technology. Using this process, new composite heat-resistant materials, highly disperse materials and thin filmswere created. These developments have made it possible to create new efficient catalysts and highly selective inorganic ion-exchange materials. Based on inorganic ion-exchange materials, a technology was developed to extract lithium from natural brines, which are poor in lithium content. On the basis of sol-gel technology, new composite matrix-isolated flocculants-coagulants were created. These reagents are designed for the treatment of natural and wastewater in order to remove impurities of oil products and heavy metals.
