In the course of the work, the main loads affecting the VST were determined, the permissible stresses of the steel material and the weld were determined, and the analytical calculation of the stress-strain state of the VST was performed without the impact of defects in the welded joints of the receiving and distributing pipe and the tank wall.The creation of a three-dimensional model of the insertion zone of the receiving and distributing branch pipe into the wall of the VST was carried out, the numerical calculation of the stress-strain state of the model was performed without the impact of defects in welded joints and taking into account this impact. This effect on the stress-strain state of the tank is evaluated

This method has several advantages and allows recycling such material safely. The optimal composition for recycling in plasma was determined. Equilibrium compositions showed that in the process of plasma processing N[2], CO[2], H[2]O and also FeCl[3] ΠΈ Fe[2]O[3] in the condensed phase were formed. Lack of soot is an indicator that the recycling process is environmentally safe
Information system for monitoring, estimates and forecastes the main vital parameters of neonatal status
Certain categories of people, as well as newborn babies require constant monitoring signs of their life in hospitals or at home. The most common reason for this observation - apnea. Apnea - a condition accompanied by a lack of respiratory movements for more than 20 seconds. Caused by various factors such as the depletion of blood carbon dioxide caused by excessive ventilation, diseases such as bronchial asthma, various pulmonary diseases, snoring. This observation is particularly relevant for their newborn children. In the light of these provisions, the relevance of this work is evident and the need to address the information system for monitoring vital parameters, estimates and forecasts status of newborns as the problems of the complex. In order to observe these main basic parameters of life, we need a punctual device, which helps monitor newborns, on the one hand and, on the other hand to obtain a correct solution with respect to time in an emergency without the need for specialist or doctor. An artificial intelligence tool, which depends on machine learning, is the best modern method for this kind of information system

The purpose of this work is to study the synthesis of hydrocarbonate magnesia structures during hardening of a hydraulic magnesia binder in water conditions.
As a result of the research: the influence of the aquatic environment and the type of system (open and closed) on the processes of hydration and hardening of magnesia binder was established
Experimental researches of mechanoelectrical transformations in tashtagolsky iron-ore field rock
Physical modeling in lab is approach of definition of main mechanical transformations behaviours inrock massive for choice of electromagnetical signals optimum characteristics and parameters ofelectomagnetical emission for developed approach of crush burst estimate. It is support connection betweenmechanoelectrical transformations characteristics and stress strain state of researched object. Physical modelingof mechanoelectrical transformations in the lab was made under a press by axial quasistatic compression of rockspecimen up to destruction. During stressing applied injections of specimens using determined acoustic signals. For researches used model and real specimens of Tashtagolsky iron-ore field rock, such as ore and matrix rock
