The relevance of the correct approach to the verification of modern electronic engine control systems of the car with regard to structural complexity, as well as the possibility of timely use of various diagnostic equipment to prevent engine failure, due to the timely detection of malfunction and reduce the costs associated with the operation and maintenance of road transport. The technology of diagnostics involves the mandatory verification of data received from the diagnostic system by measuring the corresponding physical parameters. The fault may be in the wires connecting the sensor and the control unit, in the control unit itself, in the connectors. To detect a fault, it is necessary to make a certain number of measurements of voltages, currents, and resistances and to establish the fault location using special diagnostic devices. On the basis of the obtained results, malfunctions of individual systems, assemblies, and aggregates are identified, then, taking into account indirect performance indicators, their technical condition is analyzed. In the end, it is possible to reliably assess the technical condition of the car, to detect and eliminate the causes of deviations from the norm.

Development of technical lighting capabilities maked it possible for lighting designers to implement any ideas. Although the structure of the human eye as a biological receiver of radiation is still the same despite lighting equipment progression. Many urban lighting design solutions implemented in various cities all over the world leads to promptly considering the issue of lighting quality assessment. A comprehensive study of an urban environment supported by town planning analysis allows to draw conclusions about the rationality of expended energy resources and the quality of realized objects. The relevance of luminance distribution analysis in a night city environment increases every year, especially for cities with lighting strategies aimed at a quantitative increasing of illuminated objects without hierarchy of priorities. By the example of the central part of Tula city an integrated approach to the analysis of evening image of the city has been considered, the luminance ratios were estimated for the facades located on 11 central city streets. This quantitative luminance levels analysis allows to draw objectively conclusions about the quality of existing light environment of the city and to understand possible steps for its further development in a new way.

At present, modern information technologies are actively used in the design of complex equipment at various industrial enterprises – automated systems for end-to-end CAD/CAM/CAE class design, which provide complex execution of design work with a significant reduction in their execution time while improving the quality of work. When this is achieved the main objective which is the update of the nomenclature of products, reducing costs, improving reliability, efficiency, etc. In view of this, the task of constructing and visualizing solid-state models is relevant today. From the analysis of the literature, it was concluded that today there are not enough methodological techniques for building models, and the existing developments do not contain optimal algorithms for creating 3D models of parts of varying complexity. Therefore, to implement the above problem, an algorithm for constructing a 3D model with a cutout was proposed.

The subject of research is the problem of choosing the most efficient hardware architecture that implements the algorithm for deconvolution (recovery) of distorted images. The Wiener filter is taken as the deconvolution algorithm under consideration, due to its efficiency, both in terms of image restoration quality and due to acceptable time complexity. The object of study is the process of determining the time complexity of the considered algorithm for the recovery of damaged images when it is executed on a central processing unit (CPU) and a graphics processing unit (GPU). The main functions of blurring and defocusing of images are considered: Gaussian blur, Bokeh effect, Motion blur or motion blur. The research method is based on an experimental assessment of the dependencies of the algorithm operation time based on the Wiener filter, performed on the CPU and GPU, on the dimension of the image being restored. The results of a computational experiment conducted in order to compare the dependencies of the operating time of the Wiener filter, performed on the central processor and the graphic processor, on the size of the image being restored, are presented. Based on the presented results, it was found that when using images whose dimensions do not exceed 1920 * 1080, the Wiener filter is more expedient to implement on the CPU, and when restoring images that are larger than 1920 * 1080 - on the GPU.
