A new competitive technology has been developed for the molding of structural products from traditional and nanomodified polymer composite materials (PCM) based on the use of effective low-frequency ultrasonic (US) cavitation modes in liquid polymer media. Effective processing parameters were established for the basic technological operations of preparing nanosuspensions, preliminary ultrasonic treatment, disintegration and mixing in the preparation of liquid nanomodified polymer compositions
The basic part of the problem of combining physically heterogeneous components in the creation of executive modules of automated systems with programmable control is solved.
The results of the study of the features of the emergence and maintenance of the phenomenon of ultrasonic cavitation and the revealed patterns are the basis of the original design solutions of technological cavitation equipment, which allowed to increase the efficiency of many technological processes and the reliability and operational longevity of cavitation technological equipment
The use of slit high-frequency (HF) indirect cathode sources with indirect cooling of the target for the layer-by-layer deposition of the components on the substrate with their movement over the target surface is substantiated. Designs of sources for the deposition of ferroelectric film from zirconium-hafnium oxides and lead zirconate-titanate, focused on the use of targets with dimensions 68x30x5mm from powders of hafnium, zirconium, titanium, lead oxides, have been finalized.
Models for non-Markov SP networks that use several different S-blocks in one encryption round are built, and algorithms for calculating upper bounds for differential probabilities are specified. The criteria for the practical selection of ARX cryptographic primitives with certain properties based on the automatic evaluation of stability are developed. The cryptanalysis of the new blockchain encryption standard of Ukraine "Kalina" and separate units of the blockchain encryption standard of the Republic of Belarus STB 34.101.31-2011 "BeLT" has been carried out.
“Public information in the form of open data” is public information in a format that makes it possible to carry out its automated processing by electronic means, open and free access to it, as well as its further using. Information managers are required to provide public information in the form of open data upon request, to publish and regularly update it on a state open data web portal and on their websites. Such information is permitted for its further free copying, publication, use and distribution.
New information technologies have been created to support the design, operation management and development of critical IT infrastructures. Developed technologies provide a single platform which offer PaaS solutions for critical IT infrastructure implementation IaaS solutions for critical IT infrastructure deployment and production of appropriate IT management systems which performs big data processing. New models and methods have been created for integrateddevelopment, management, operation and
A new generation of non-invasive acoustic system has been developed for measuring critical physiological parameters of the brain and human inner ear snail, which includes: Dynamic, real-time, single-channel passive acoustic thermometer with focus, which records its own thermal acoustic radiation of the human body in the megahertz range, and is safe for it, and is intended for non-invasive determination of deep temperature of the human brain and snail of the inner ear of the human; Computer complex, with electroencephalograph and headsets, for determination of frequency and power of brain rhythms, and implementation of non-invasive acoustic method of therapy with the help of complex audio-signals.
The increasing complexity of modern information systems, including grid / cloud infrastructures, has led to the expansion of a modular approach to developing their software using standardized interfaces between parts, as foreseen by the Service Oriented Architecture (SOA) concept. This architecture is presented as a set of services and processes that can be combined, and modified over time according to changes in requirements with the help of workflow schedulers (workflows).
