This article is about intellectualization of the software of processing spatial data. Solution of this problem based on using the ontology approach. Next tasks were solved to achieve the goal: to consider the analysis of the subject area, to create the ontology of considered subject area, to develop an algorithm of creating and integrating the ontology to the software of processing spatial data. This algorithm is allows to integrate spatial data from different storages. Also the structure of the ontology is considered in this article: what components are included in the ontology and how could we create it. The software Protégé is chosen from existing editors to create and edit the ontology.

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.

This article considers the influence of a structuring additive on the physical and mechanical properties of aerated concrete. As a structuring additive, a by-product was introduced into the composition of the aerated concrete mixture by cutting the top layer of the "gorbuschka" in an amount of 10 to 30%. Comparative analysis of the results of physical and mechanical tests of aerated concrete samples with different amount of structuring additive showed that its introduction increases the compressive strength, while simultaneously increasing the density of aerated concrete. At the same time, the value of the constructive quality factor in GB4 (with 20% of the "gorbuschka") is 20.4% higher than in GB2 (with 30% of the "gorbuschka") and 31% higher than for the aerated concrete base composition GB1 (control) that allowed us to take him for the optimal composition in further research.

Modelling and experimental research of filter onhalf-wave resonators with quarter-wavelength links was made. The following experimental result were received: - center frequency was 3.7 GHz; - passband width was 230 MHz; - losses in the passband were not more than 4 dB; - bkocking at tuning ± 200 MHz was not less than 40 dB. It is recommended to use the filter in a microwave receiver input circuit.

In the article the results of reinforcement of monolithic reinforced concrete slab bezbalochnyh, different parameters of a finite element mesh, under other equal characteristics. Of course cell model was created by means of PC SAPPHIRE with subsequent transfer of analytical model in LIRA-CAD when creating analytical models used three variants of triangulation, namely: rectangular, triangular and adaptive step triangulation ranged over a wide range-from 1/6 up to 1/30 span. Bearing slabs at columns was carried out on two variants : using an absolutely rigid body and without it. The subject analysis of selected area of the upper longitudinal bearing fittings. During the analysis process was investigated the influence of automatic finite element mesh triangulation on anchor square fittings. Found that in all cases an increase in triangulation step reduces the required for calculating the square top of the longitudinal reinforcement. This reduction may reach 85%, and in case of insufficient quality control finite element mesh is going to cause a serious error in the calculation. When automatically generating a mesh leaf size can significantly exceed step triangulation. All meshes with the zone of transition from AGT to the plate in the form of triangles effect is observed the increase required for calculating reinforcement as you go further away from the brink of columns, that in our view it is illogical. Practical value as the most simple way, has the option of split slabs into rectangular finite elements with a size equal to or slightly greater than the section of the column. without the use of absolute hard bodies.

Issues related to the safe operation of the transport system as a whole. The article touches upon the questions on how to repair the car in Volgograd. In the city, this guide is the only link in the area. Long-term operation of the overpass led to the accumulation of a large number of defects and damages that prevented it from being fully used. Accounting for all aspects of the safe use of the way to ensure its sustainable functioning. The measures ensuring the safe operation of transport facilities include: increasing the dimensions of the roadway of the overpass, strengthening structures to increase the carrying capacity to normative work, processing and storing seismic precipitation on the span, installing a video camera for rapid response in case of traffic accidents and illegal actions. To increase the load-bearing structures, the new beams should be replaced with new beams, designed for high loads, and also use composite reinforcement with carbon fiber.

The general equations of the moment theory of a circular cylindrical shell with creep are considered: static, geometric and physical. We solve the problem of determining the stress-strain state of a shell rigidly clamped in the base when an internal hydrostatic pressure acts on it. The problem has reduced to a linear nonhomogeneous differential equation of the fourth order with respect to deflection. The solution was performed numerically by the finite difference method in the Matlab software package. As a law of connection between creep strains and stresses, the generalized nonlinear Maxwell-Gurevich equation was used. To determine the creep strains, a linear approximation of the first time derivative was used. The shell was made from secondary PVC, and as a result, it was found that in the process of creep in the shell, the circumferential stresses increase by 15%.
