The modified method window exponentiation elements of field GF(p), four algorithms implementing this method and software was proposed. The idea of the proposed method can be applied to the problem of scalar multiplication of points of an elliptic curve over an arbitrary finite field.
In the energy sector of Ukraine there are a significant number of different power boilers, furnaces, drying, gas turbines etc., which exhausted their service life. The experience in the operation of such systems has shown that one of the problems of their functioning is a significant discrepancy between the actual and the calculated distribution of the heat flow in the combustion chamber. This results in thermal distortions in the equipment elements occurrence stresses and lead to crash.
The main scientific results are the services processing technology with the integration of information resources in the request service systems, that will allow significantly increasing the efficiency of technical resources in the provision of services to communication subscribers, allow for distributed processing of requests for user services and their billing, allow improving the quality of customer service and increasing the intelligence of service process.
The vision system for the high dynamic range (HDR) video signals is developed. The system performs the HDR image compression to the signal with dynamic range of 48 dB without loss of sharpness in the light and dark areas and no artifacts, and has moderate hardware costs when it is implemented in FPGA. The Retinex compression algorithm based on the bilateral function is considered. A simplified HDR compression algorithm is proposed, that uses the intelligent image analysis of local characteristics instead of the bilateral function .
