An experimental study of the resolving power of the rank detector of single pulses was carried out. Experimental dependences of the probability of detection- resolution of two pulses on the time position from the delay between the pulse fronts-are obtained. It is shown that the probability of correct detection - resolution reaches the value P101 = 0.5 with a signal-to-noise ratio = 2 for a delay between fronts of about 9,7 μs, and for a signal-to-noise ratio of 4 with a delay between fronts of about 9,1 μs.

Background: The quality of electricity is one of the main problems necessary for the normal functioning of responsible technological processes in which a slight distortion of the supply voltage can lead to a violation of the normal operation of enterprises. There are several solutions to this problem: uninterruptible power systems, fast automatic power reserve technology (FAPR), dynamic voltage distortion compensator (DVDC). The most interesting solution is the application of dynamic voltage distortion. Material and methods: The principles of constructing a dynamic voltage distortion compensator with multilevel voltage inverters are investigated. An imitation model constructed under the following assumptions is proposed: an ideal case of the main circuit system (without higher harmonics) is considered, the nonlinearity of the transformer is not taken into account, short-circuit currents are absent, only constant load power is used. Assumptions are justified by the fact that in practice their error is no more than 3-5%, which is permissible. The results are obtained by modeling the system in the MatLab 2016b package. Results: A fundamentally new structural and functional scheme of a dynamic voltage distortion compensator with a multilevel system is developed. The requirements for the dynamic compensator of voltage distortion, load, LC-filters, current-voltage transformers and a converter are determined. Simulation of the simulation model has shown that the system works and corresponds to the expected results. Conclusions: The proposed voltage compensation system will solve the problem of the normal functioning of technological processes. The simulation results showed that the declared functional of the DVDC provides compensation of the voltage level in a given range of voltage dips. The obtained results can be used to stabilize the power supply: in the power supply systems of medical institutions, electric transport, critical energy facilities of a high category.

The problem of formalizing the elastic line of a thin steel strip of great flexibility arose in the process of creating elastic elements with a nonlinear characteristic for use in various kinds of damping devices. Such elastic rods experience large displacements when the material operates within the elastic range, in particular when axial loading in the supercritical region, when the axial load exceeds the Euler force, but in the subcritical region the movements are not significant enough to obtain a regressive-progressive characteristic.The paper investigates the possibilities of softening the elastic characteristics under axial loading in the initial period by applying a rigid cantilever arm mounted on the end of the elastic rod with a vertical load applied to it. Simultaneously, the influence of the vertical force on the elastic characteristic of the circular trajectory is investigated. To formalize the stress-strain state of a thin steel plate of great flexibility, the method of elliptic parameters is applied. The resulting elastic characteristic actually has a regressive-progressive character. The results obtained using the ANSYS computation complex for a system with given geometric parameters correlate quite well with the theoretical dependences derived. It follows from the diagram that the eccentric compression of the elastic element forms a regressive part of the elastic characteristic, and the circular trajectory of the point of application of the vertical force forms a progressive section.

The work is devoted to research of influence of laser visual stimuli on the functional activity of man. The analysis of changes in the tempo of psychomotor activities in promoting human dynamic images of laser graphics. Stress is a state of severe and prolonged psychological stress, which occurs in a person when his nervous system gets emotional overload. Stress is an integral and constant companion of our life because the phenomenon of stress is inherent in every organism. The main objective is the minimization reasons, namely the negative impact of stress on the psychophysiology of the person, and therefore his health and functional activity, and the consequence - the effectiveness of his work, and therefore factors as personal performance of the employee and of the organization as a whole. Alternative to conventional drug and non-drug methods of preventing and dealing with stress, is audio-visual stimulation, which is based on the fact that music and color can have a strong influence on the brain.

A manganese-vanadium concentrate precipitate containing V2O5 and MnO2 is formed on the stage of wastewater ozone treatment in sodium technology of vanadium-containing converter metallurgical slag processing. Vanadium content of the slag changes between 4 and 15 % wt and manganese content changes between 62 and 75,5 % wt. The article examines influence of concentrate with 14,33 % wt V2O5 and 65,44 MnO2 % addition in slag-with-soda furnace feed to determine positive effect on the result of roasting. Vanadium content of the slag is 22,34 % wt expressed as V2O5. Roasting temperature is 850 °C, Na2O/V2O5 molar ratio is 0,5:1, the concentrate is added as 0,25; 0,5; 1,0 mass ratio on the content of soda in starting furnace feed. Degree of vanadium conversion in water- and acid-soluble compounds is increased. The most effect is provided on the process of interaction between vanadium oxides and spinels with sodium compounds with formation of water-soluble vanadium forms. The optimal addition of concentrate is 0,25-0,5 mass ratio on the content of soda. Increasing of concentrate content is not effective. Both manganese and vanadium contained in concentrate give positive effect. Concentrate addition can be recommended for existing industry regardless of type of alkali addition on the stage of roasting.
