Abstract

In many problems of the system analysis a graph theory is widely used, which allows using the mathematical apparatus of analysis of binary matrices to obtain important information about the internal structure and properties of the simulated objects. In particular, algorithms for proper numbering directed graphs are used in problems of topological sorting acyclic graphs. The article deals with the universal topological sorting algorithm that allows for the correct numbering, including contour digraphs.

Method to improve accuracy mass measurement fluid in the tank
Solntseva A.V., Skvortsov B.V., Borminsky S.A.
Abstract

Considered two methods to improve the accuracy of measuring the mass of fluid in the tank based on the non-linear interpolation of the experimental calibration data. The first method is to find a transformation function mass and the total parameters of the fluid measured by monitoring with the help of the calibration model of the measurement process. The second method is based on the determination of an individual analytical dependence for the tank, connecting a lot of fluid, with its qualitative and quantitative parameters.

Theoretical basis of directed energy transmission pulses in stationary and moving media
Skvortsov B.V., Skvortsov D.B., Malysheva–Strojkova A.N.
Abstract

The work is described mathematically by an energy field created by emitting a pulse as it propagates in an inhomogeneous absorbing medium. We give a three-dimensional mathematical description of the algorithm and the propagation of pulse signals sent in inhomogeneous absorbing stationary and moving media. Determined by the pulse energy and the group velocity. Changing the amplitude and spectral composition of the pulse passing through the medium under investigation provides diagnostic information about the environment.
