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 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.

A thin circular disk is considered, the material of which exhibits elastic and plastic properties under thermal and force influences. In the central part of the disk, the temperature field is uniform. At the boundary of the disk, pressure and a constant temperature are set. Approximation of a plane stress state is adopted. The additive form of the connection of full, elastic, plastic deformations and deformations under free thermal expansion is considered. Elastic deformations are expressed in terms of stresses according to Hooke's law. A linear approximation of the dependence of the plasticity limit on temperature is proposed. The possibility of neutral loading of the central region of the disk and its external boundary is shown. Especially distinguished is the condition for the plasticity of Tresca.

The steps of constructing an algorithm for calculating the stressed and strained state of a thin circular disk experiencing thermal and force effects are discussed. A homogeneous temperature field is created in the central part of the disk. Within the framework of the theory of the flow of an ideal elastoplastic body, conditions of general plasticity are considered. It is assumed that the plasticity limit for uniaxial tension is common for all plasticity conditions. Dependencies between the disk radius, the temperature of the central region of the disk and the external pressure, which determine the appearance of plastic regions, are established. For piecewise-linear plasticity conditions of general form, analogous dependences are defined, when singular plasticity regimes are realized at elastoplastic boundaries. For different values ​​of the input parameters of the problem, the stresses, equivalent stresses and the hodograph of the stress vector are given.
