Statement of the problem and purpose of the work. The technology of machining hard-to-machine materials, which undoubtedly include high-alloy steels and chromium and nickel-based alloys, has some advantages over traditional abrasive machining methods. Among the most significant advantages, researchers note greater flexibility, faster changeover to other types of parts, the ability to combine several operations into one due to the versatility of the forming motion of the blade tool compared to the abrasive, higher productivity, and relatively low technological cost.

The article presents modern schemes for the organization of wind-solar power supply systems. Available approaches to managing the energy-dynamic process of operation of wind power plants as part of hybrid power supply systems are given, and modern research on this topic is given. The results of the development of a mathematical model of the energy-dynamic processes of the hybrid wind-solar power supply system, which includes wind power plants, solar panels, and a battery energy storage system. The universal structural diagram of such a system is substantiated.

Research results, using which the method of minimization of public transport delay is improved at intersections with the system of coordinated motion control, are given in this paper. Such transport research was carried out with simultaneous application of field measurements of the study of traffic flow indicators and computer simulation in PTV VISSIM to check the level of efficiency of coordinated control and the reliability of the results.

The method and results of transport research, carried out by field research method, on the determination of the main indicators of traffic flows with significant unevenness of the movement on the arterial street in conditions of coordinated control is reviewed in the paper. Time parameters of traffic light control for which a reduction in traffic delay is achieved in direct and opposite traffic flow by the change of permissive signal depending on traffic intensity are determined using the simulation method.

Досліджено вплив інтегральної нелінійності функції перетворення інтеграторів сигма-дельта модулятора другого порядку на інтегральну нелінійність функції перетворення модулятора загалом. За результатами досліджень визначено вигляд функції нелінійності модулятора та коефіцієнти впливу кожного інтегратора.
