Thromboelastometry is a method of assessment of system of a hemostasis based on continuous graphic recording of clots stability in time of their formation and the subsequent fibrinolysis. An algorithm for differential diagnosis of hemostasis disorders was developed based on thromboelastometry data, which served as the basis for the development of mobile applications to assist in the development of an algorithm for analysis and interpretation of thromboelastometry results.

The article presents nonlinear theory and calculating efficiency of the new type electronic device - frequency non-magnetic doubler-klystron with a transverse modulation and a strip relativistic electron beam. In contrast to the known design of a frequency doubler-klystron with using transverse modulation authors apply an electrostatic lens for electronic grouping. The latter allows the use of cryogenic superconducting electrodynamic systems, which is very important for high-power devices of the terahertz range. Moreover, there isn't necessary for additional energy consumption in the present construction due to the electromagnetic lens absence.

An achievement of maximum accuracy characteristics of aircraft area navigation is possible only using the optimal pair of navigational aids.

A generalized method for the automated design of technological processes for the production of MEMS accelerometers is developed. This method is based on two methods: the method of selecting a standard technological processes and the method of searching for analogues of individual subsystems and elements of MEMS accelerometers, which will increase the efficiency of design work by reducing the cost and time of manufacture. Within the framework of the method, decision-making model to select the type of MEMS accelerometer for its functionally constructive parameters, model for searching analogues of individual subsystems and MEMS accelerometer elements, as well as a model for selecting equipment that, based on 4 indicators: productivity, energy efficiency, equipment price, service have been developed.
