The solid-state electrically tuning filters are main elements of different multifrequency communication systems with high reliability. New approach to designing electrically tuned band-pass filters that is based on use U-shaped microstrip resonators with several varactors connected to each resonator is proposed. This approach allows to creating prototypes which exceeds world level of varactor-tuned filters.
Technology and experimental equipment is developed for realization of processes of synthesis of biogas. The rational parameters of process are certain at the terms of processing of wastes of agricultural production and communal enterprises. On the basis of the conducted researches hydrodynamics is certain and and transmission of mass of description of processes of biosynthesis of, which take a place in an anaerobic farmantors from immobilisation on inert transmitters microorganism.
The analysis of the modern state of program and technical operative diagnostics facilities of the building objects stress-deformed state under difficult engineer-geological and seismic conditions is conducted. The theoretic-methodology ground of experimental methods of complex geophysical researches of the litodynamic earthly surface processes for industrial explosions on an iron-ore quarry the "South ore mining enterprise" is executed.
Autonomous storage plant of the new kind for domestic water heating by means of solar energy is the object of the development, and solar thermal collector of the new kind, which contains high-performance heat transfer devices – heat pipes as a core, is the subject of the development. For the first time in Ukraine operating mock-up of the plant, which functions without electric power consumption, has been manufactured; its working thermal efficiency value is within 0.5 – 0.65, and maximal obtainable temperature value of the heated water is 65 C deg.
