ARCHITECTURE OF A GRAPHICS ACCELERATOR VLSI WITH PARALLEL COMPUTING STANDARDS SUPPORT
Annotation: The article analyzes modern approaches and standards for describing general-purpose computing for graphics accelerators according to the GPGPU (General Purpose computing on Graphics Processing Unit) approach. The prospects for the implementation of an ultra-large integrated circuit oriented towards parallel computing in accordance with general-purpose tasks, while supporting the construction of the display of graphic images as an auxiliary function, are considered. Similar to the Nvidia Quadro GPU, such VLSI can be used for workstations that perform computational tasks such as CAD, solving systems of differential equations, spectral and wavelet analysis, statistical data processing, machine learning and similar classes of calculations running on a large number of parallel computing nodes. The presence of standard approaches to the description of general-purpose computing makes it possible to base the design process on existing high-level computing models, focusing on their hardware support. At the same time, performance in tasks that are typical only for the construction of threedimensional images can be reduced by increasing the efficiency of VLSI in general-purpose computing.
ALGORITHM OF AUTOMATED MONITORING OF THE TECHNICAL CONDITION OF POWER TRANSFORMERS OF POWER DISTRIBUTION SYSTEMS
Annotation: The service life of power transformers and the inter-regulatory periods specified in the regulatory and technical documentation are calculated based on certain regulatory conditions in which the transformer is operated. However, these conditions may differ from the regulatory ones, which affects the service life of transformers. Taking into account the intensities and current operating conditions, which can be implemented using the presented algorithm for automated monitoring of the technical condition of power transformers. The algorithm under consideration is based on the developed mathematical models of the actual actuated resource and operational reliability of transformers, which take into account the intensity of their operation. The presented algorithm can be used in the modernization of existing automated integrated systems of dispatching control of electric power networks, as well as in remote monitoring systems of electric power equipment. The developed algorithm of automated monitoring is an actual solution within the framework of the program «Digital economy of the Russian Federation».

SHARING A FREQUENCY ANALYZER WITH A CONCEPTUAL FRAMEWORK TO IMPROVE THE PERFORMANCE OF A DECISION SUPPORT SYSTEM
Annotation: Research in the field of the conceptual structure of the text allows you to more accurately determine the weight criterion of keywords and exclude from the list objects that less reflect the reliability of the information obtained from the document. Based on the data obtained, the system can be upgraded and receive constant support in the form of updates to the databases of relevance of search queries and calculation of criteria for weight characteristics. The designed decision support system can be implemented in large systems of Internet resources, used as an independent project supporting autonomous operation, through the introduction of dictionaries of words and rules with the possibility of updating, or for implementation in intelligent systems.

ASPECTS OF AUTOMATED INTERACTION BETWEEN DRONES AND UNIVERSAL PLATFORMS
Annotation: Research in the field of self-assembly platforms for drones is relevant, due to the growing interest in the application of UAV technologies in the human environment. The use of drones allows you to automate some of the work of a person, shifting his functions to various systems, the key element of which is an unmanned aerial vehicle. However, the UAV has a significant drawback, expressed in battery capacity, and the problem of size scaling, which also rests on it. In order to solve this problem, it is proposed to use self-assembled drone stations, which will act as autonomous points for launching and charging drones, and also be used as a communication channel between the drone and the server.Such a station takes over the job of establishing a stable signal around itself and broadcasts it to neighboring stations, due to which it is possible to achieve good coverage in places where there may be no connection at all. This development will be promising in hard-to-reach areas, in order to expand the range of operation of an unmanned aerial vehicle.

INFORMATION SYSTEM FOR RECORDING THE WAGES OF EMPLOYEES WITH ARTIFICIAL INTELLIGENCE MODULE
Annotation: The article discusses aspects of designing and implementing an information system for accounting for the wages of employees of an enterprise with the introduction of modules for analyzing and calculating the amount of labor to automate the business processes of an enterprise. As part of business decision support, mathematical features of building an analytical module based on machine learning using a linear regression algorithm are considered.
SOFTWARE IMPLEMENTATION OF METHODS FOR SOLVING CONFLICT PROBLEMS
Annotation: The article is devoted to the software implementation of numerical methods for finding solutions to conflict (gametheoretic) problems. The system of conflict equilibria developed by E.R. Smolyakov was chosen as the main tool for solving such problems. Algorithms for solving problems with utility functions of participants are given in the form of matrices and continuous functions. In order to increase the performance of the algorithms, they are adapted to the architecture of parallel computing nVidia CUDA.
