Proposed new structure of the patented DSP-audiometr, and developed its new Simulink-based model, which is provided and playback keys (in the range from 125 Hz to 16 kHz), broadband and narrowband test stimulus, and the implementation of a number of above-threshold procedures (tests Fowler, Lusher, SISI and Stenger).
The influence of the kinetic parameters of the process of directional solidification from the melt and directional sintering in the dispersed state, crystal chemistry and diffusion properties of the initial components, energy parameters of elastic waves, the nature of alloying components on the structural and geometric characteristics of the phase components of ceramic composite materials are investigated.
The method of determination of parameters of clinical focus of presbiopic eye is based on the analysis of three-dimensional distribution of luminosity in the zone of geometrical back focus of the optical system of eye.
In theory obgruntuvani possibilities of complex satiation of staley and alloys by titan, chrome, vanadium, nitrogen, carbon, set conformities to law and features of forming on-the-spot of wares of multi-layered coverages with a heterogeneous structure on the basis of carbides, nitridiv, oxides of transitional metals, aluminium, with the high complex of physical, mechanical and chemical properties for the increase of production indexes of details of machines, instruments, rigging.
The main scientific and technical idea of work consists in complex use of the combined temperature elastic deformed method of devulcanization by compression of the crushed rubber waste with simultaneous shift and deleting at separate temperatures, and also development of the advanced patento-protected design of the equipment for realization to the process of devulcanization of the crushed worn-out tires and rubber products and receiving high-quality powder and a crumb which could be used in its pure form to the process re-vulcanized rubber as a supplement to, and for receiving other composi
Created an electrochemical gas sensor NTUU "KPI" for determining hydrogen sulfide, which endowed of high resolution and selectivity and can be use for manufacturing automation, quality control, safety, security and anticorrosive protection of the environment. Made a set of theoretical and experimental studies to determine the kinetic parameters of the redox reactions and mass transfer in electrochemical systems is based on solid and electrolyte matrix to enhance the selectivity and resolution and cost savings generated by sensors.
Existing models and techniques of calculations of process of cooling of one- and multi-layered polymeric pipes of different function are analysed, the major factors influencing stability of process and quality of finished goods are considered. It is established that existing models and techniques concern only single-layered smooth pipes.
Analyzed the causes of abnormal and dangerous situation in the operation of unmanned aircraft and general purpose aircraft, manned by a single pilot. It is possible to determine the number of events that will lead to a decrease in dangerous situations during the flight of the aircraft: carrying out timely maintenance and monitoring of the physical and psychological integrity of the pilot at his control of the aircraft, correct and timely assessment of the weather conditions, applying for aircraft auxiliary / reserving devices and systems.
The essence of development is that for the first time in spot welding of dissimilar materials to enhance quality connections and guaranteed their support for a given level of applied external electromagnetic action. Their essence is that during the welding process each point in the working area generated transverse inter-symmetric magnetic field. In their interaction with the welding current in the melt volume arising ponderomotive force that it intensively stirred. Thus there is some positive effects.
The process of forming the corrugation with different geometrical parameters is investigated. The analysis of the indicators formability and the ability of polymeric material for welding is executed. The dependence of the wall thickness of the corrugated pipe for sloping walls, for vertical walls, for high and low profile, for different shapes set at different angles of the walls forms, for different width and height corrugation, for different sizes of products is determined. The technology of forming a two-layer corrugated tube of thermoplastic material is developed.
