The problem of transmitting an image in a transmitter-receiver system over a noisy data transmission channel in JPEG 2000 and JPWL format under conditions of a previously unknown and varying intensity of noise is considered. This task is considered for the conditions of the IP network. The article aims to build methods for estimating the intensity of noise by the JPWL decoding results in the receiver and dynamically adapting the parameters of the JPWL transmitter to the current assessment of the noise intensity, ensuring the highest quality of the decoded image with the shortest length of the transmitted encoded stream. An experimental study of the relationship between the parameters of JPWL, the intensity of noise and the quality of the decoded image was carried out. It is shown that for any JPWL parameter there is a region of one-to-one correspondence between the percentage of fully recovered tiles and the probability of losing a network packet. A technique for estimating the intensity of noise by the decoding results of a single image is described. This technique can be expanded to use the results of decoding a series of images.

The article is devoted to the issue of improving the environmental safety of the construction industry by improving dust collectors of dust removal systems for the aspiration schemes of the construction industry/ It was proposed use additive-integrated dispersive analysis of variance of dust particles emissions throw out into the atmosphere by aspiration systems. The article proposes the improvement of complex analysis of variance using hydrodynamic criteria in output functions. Modified output data and additive-simplex allows getting approach to evaluate characteristics - equivalent sizes and speeds of sedimentation-soiling of dust particles with a higher degree of accuracy of the results. It makes possibility to determine the ranges of size’s and velocities’ changes with real ability. It is possible to obtain more reliable data of sedimentation rates and equivalent particle sizes for the studied dust samples of building materials using the distributions of the hydrodynamics criteria. Analytical approach to determining the density’ distribution of the numerical values of the hydrodynamics criteria in the output function allowed us to clarify the more real values of sedimentation rates and the equivalent particle sizes and the range of their changes both. This way analysis of variance of dispersed dust particles could call additive-complex or simplex approach. The obtained regressions in processing the research results were used in the development of devices for capturing dust of dispersed building materials from emissions. This way could significantly reduced dust leakage out from aspiration collectors of decreasing dust systems while purifying emissions at the building enterprises. This approach is one of the most effective ways to improve the environmental safety of the building industry.

The article describes the algorithm of recognition of schematic diagrams in the framework of structural design of complex technical objects. It is specified that at statement of a problem of development of the specialized vectorizer it is necessary to define: software subsystems of the simplest tracer; algorithms of the analysis of images; formats of representation of the end result; initial data (formats) for recognition. As a result, it was concluded that for structural and circuit design, during which the vertex of the final portrait of the graph of the projected system is replaced, obtained after optimization by the criterion of the set of the smallest external stability, it is necessary to recognize images of graphic elements. The proposed algorithm allows for adequate recognition of the elements of electronic circuits, which further makes it possible to automatically replenish the database of elements with new elements in a given format.

The compare the durability of the existing ball bearings (SHO) with the polymer homogeneous element with the durability of the modified supports, a cell model with the averaged placement of the modifier in SHO substrate and a model for bringing the multilayer sho body to the equivalent single-layer one are constructed; calculations of contact pressure, contact deformations and stresses are performed. The calculation takes into account the rheological and physico-chemical properties of the components of SHO substrate and modifier, the influence of the environment. As a result of calculations, it was found that at all points of the contour the material experiences a biaxial plane two-dimensional stress state, called pure shear with the presence of shear stresses. The most intense point of danger is the point lying in the center of the platform of contact of details.

The paper considers the main factors determining the quality of underground water deposits within the RO, done hydrochemical and geoecological assessment of groundwater RO. The entropy of the groundwater ecosystem is calculated. It was found that most of the deposits have an entropy of less than 30%. that is, the water is clean enough, not experienced external influences. However, the water quality has deviations in individual indicators from the requirements of SanPiN 2.1.4.1074-01, which can be eliminated by conventional methods of water treatment.

The aim of the work is to verify the accuracy of the solution of the traveling salesman problem by the method of branches and boundaries with a large difference in the length of the chords of the transport graph. It is considered an NP-hard task. It is proved that the Vig method can not give an optimal result in a transport graph with a large difference in the values of the elements in the cells of the original matrix, when its zero cells will have very different estimates. The reason for the inaccuracy of solving the travelling salesman problem is the inadequacy of the adopted model for the calculation of the original formulation of the problem. It consists in the injustice of the second hypothesis on the evaluation of the zero element in the evaluation matrix included in the optimal route. The hypothesis is accepted without strict proofs and has probabilistic character. The use of the minimum values of the row and column from the matrix is appropriate, as determined by the route of the smallest length. It is doubtful whether it is true that there is always a need to strike out at each stage the zero element with the maximum total score. The reason is that, firstly, it has a random character in General. Secondly, this assessment does not take into account all possible combinations of combinations of branches giving the optimal combination, since their recursion is not carried out. The technique of improving the method of branches and boundaries is proposed, which consists in additional verification of the obtained optimal route by removing the branch with an estimate one step below the maximum at each stage of branching. Numerical experiment is carried out.

In this article, we propose methods for designing fault-tolerant structures for Field Programmable Gate Arrays (FPGAs) by forming an internal structure of macro cells (LUTs), with the possibility of correcting single reversible faults in the circuit’s gates. To improve fault tolerance, the failure tolerance of a typical macro cell was assessed, the most vulnerable areas were identified and the most vulnerable parts of the macrocell were protected by means of triple modular redundancy methods. Depending on the expansion of the protected area, various versions of the built-in redundancy were obtained, and various options for minimizing the built-in redundancy were proposed. Experimental work was carried out to form fault-tolerant ISCAS'85 combinational circuit designs in the basis of fault-tolerant FPGAs.
