Development and research of heat dissipation means from high power transmission modules for antenna systems of perspective radars.

About 70 to 75% of the energy consumed by the elements of transmit modules (TM) for active phased antenna arrays (APAA) is converted into heat. This heat, if dissipated inefficiently, can cause the element base to overheat, thus reducing the reliability of the radar. The task of ensuring the normal thermal regime of TMs for APAAs is complicated by the large-scale integration of electronic components inside the TMs.

Dynamic models of energy flows of buildings are in the context of functioning of the engineering’s systems and business activity of users

Functionality of Smart Houme has certain limitations, among which is the inability to analyze the activity of the residents, determine its impact on energy consumption, identify the physical state of the user by his activities. There are no solutions that would be able to solve this
problem today. One approach is to use the activity analysis of binary motion sensors. The advantage of this approach is the low cost of implementation and privacy of the residents. The system functions in real time.
