The following work is concentrated on the analysis of dynamic pressure distribution of a brake pad by using ANSYS software. A non-linear contact analysis of brake disc has been performed using Finite Element Method. The finite element model of disc and pads have been developed, and followed by an inclusive simulation of the contact analysis of disc brake system using ANSYS software. A detailed finite element model of a disc brake assembly was developed. Contact analysis was done to determine the pressure distribution, interfacial contact area and normal contact forces under both frictionless (μ=0) and frictional braking conditions. The influence of varying friction coefficients and the brake hydraulic pressure on squeal occurrence is examined. The results illustrated that the contact pressure distribution and the magnitude of normal contact pressures are far greater towards the leading edge of the pads comparing to the trailing edge.

The analysis of the influence of heating on the depth of polymerization of composite materials of light curing is carried out. An electronic micrometer was used to measure the polymerization depth. The greatest difference in the depth of polymerization before and after heating was obtained from Filtek ULTIMATE "3M ESPE" composite material. The smallest difference in the depth of polymerization before and after heating of Nexcomp "MetabioMEDCo". After heating, the plastic and flow properties of the materials are improved, which improves the adaptation to the walls of the cavity during the restoration.

In this paper, an analysis of the problems and tasks arising from the design of situational awareness tools has been carried out. As a result, it has been established that the approaches in this area do not satisfy the requirements for modern intelligent tools for operational decision support for the reasons for the lack of methods and tools reflecting the dynamics of information processes and a distributed information processing architecture with weakly structured properties. The methods of operating and extracting knowledge from semistructured dynamic information are proposed.

The analysis of reliability of systems of an electricity transmission during which the main causes of the power outage in the consumer were identified. With the help of computer simulation, the results of operation of autonomous inverters are obtained with different number of voltage levels. The prospects of using the devices for balancing the incomplete-phase regimes on the basis of multilevel voltage inverters, which improve the reliability of power supply to consumers, are considered.

The modern schemes of phase shifters used in radio receivers, antenna systems, synchronous detectors are limited in a wide frequency range to dependence of phase shift at the release of the scheme from the frequency of an entrance signal. In this work the new scheme of the programmable phase shifter which allows to use the phase shifter in the wide frequenciest range irrespective of the frequency of an entrance signal and also to carry out a phase displacement with a high precision is offered.

Every year, the problem of recycling industrial waste in the construction sector is becoming increasingly important. Recycling and recycling of waste is an important way to reduce environmental damage. For more than one decade, developing technological processes and installations for the processing of concrete and reinforced concrete. Annually in Moscow, about 11.5 million tons of construction waste are generated, and in the near future the increase in the volume of concrete scrap in the demolition of buildings, reconstruction, overhaul and accumulation of substandard structures will reach 13-15 million tons per year.
