The article presents the results of theoretical and experimental studies aimed at the determination of optimum conditions of the ultrasonic action (geometry of the technological volume) for the cavitation treatment of high-viscous and non-Newtonian liquids. Developed model of the generation of the cavitation area lets determine distribution of the cavitation zone in the technological volumes of various sizes and forms. Carried out experimental studies allow prove adequacy of the proposed model and possibility to increase the volume of developed cavitation zones by the optimization of the conditions of ultrasonic action.

Article briefly describes results of works on identification of fire factors, characteristic for burning substances which are most often used in everyday life. Most common factors of combustion substances classes “A”, “B”, “C” and their subclasses were identified. Analysis of the acquired data may be used to identify the burning substances. Fire detection methods which will be used in the combined fire detector are also chosen: temperature, smoke electro-optical and gas-analytical.

Processes of thin sulfide layers on HgCdTe surface formation by anodic sulfdization were investigated in this work. 0.1M Na2S in ethylene glycol solution was used as an electrolyte. Potentiodynamic curves obtained do not correspond with expected ones from literature [1], but qualitatively represent electrochemical processes occurring - formation of cadmium, tellurium and mercury sulfides. Galvanostatic dependencies verify formation of non-insulating films a composition of which depends on anodization duration. Analysis of the surface chemical composition by XPS has shown that the main components of sulfide films formed are cadmium and mercury sulfides, with tellurium sulfide nearly absenting. The model of sulfide layer formation based on experimental data obtained has been proposed. Voltage-current (I-V) characteristics of Au-native sulfide-HgCdTe structures being rectifying were obtained and analyzed.

In this article the new modified topology of quasi-Z-source inverter (qZSI) is proposed. Modified qZSI allows a stand-alone power system to operate in idle mode without need connect a ballasting resistor. Time diagrams of voltages and currents of proposed topology simulation are presented. The comparison of characteristics of new topology with characteristics of conventional qZSI was conducted.

High-speed (no more than 5 ms) fame detectors with the reduction of optical noise are required. Flame detectors are required which are possible to unite into a system.
