  • Methodology for increasing the efficiency of managing resource-intensive tasks in distributed computing systems

    Currently, the problem of increasing the efficiency of managing resource-intensive tasks in distributed computing systems is quite acute. Analysis of existing task dispatching algorithms for traditional computing systems showed the limitations of using these methods in heterogeneous systems, as a result of which significant delays can occur between task switching.A functional mathematical model for estimating the workload of distributed computing systems is proposed, based on determining the probability of downtime of the processing center as a criterion for assessing the system load. Using this model will provide increased efficiency in managing resource-intensive tasks in distributed computing systems.

    Keywords: mathematical model, distributed computing system, processing center, loading

  • Modeling biological structures using electrical equivalent equivalent circuits

    The article discusses several equivalent circuits constructed by sequentially connecting circuits for the membrane and protoplasm. The solution was made using the Cardano formula for cubic equations. The roots in the expression for the determination of resonant frequencies determined the resonant frequencies for the given parameters for the membrane and intercellular fluid; to obtain numerical values, values ​​were used within several permissible limits. In the course of the calculations, it was confirmed that most resonant frequencies are in the millimeter and submillimeter ranges. It is also shown that the cell vibration frequencies occupy the decimeter, centimeter, millimeter and submillimeter wavelengths. Obviously, it is the impact on biological systems of electromagnetic radiation in the indicated wavelength ranges that will be most effective and can lead to a maximum biological response (effect).

  • Investigation of micro-dimensional metal structures obtained by electric explosion of conductors (part 2)

    The article presents the results of experimental studies of the parameters of micro-sized metal particles and sprayed films obtained by the method of electric explosion of metallic conductors (EVP) and electro-explosive spraying (EVN), respectively. Copper (Cu) and aluminum (Al) metal wires were used as explosive conductors. Geometrical parameters and physicochemical analysis of the obtained microparticles and thin films were carried out by means of the universal two-beam electronic system Versa 3D. From the analysis of the obtained samples of sprayed thin films and fine particles, it follows that with a discharge current density J≈10 ^ 10 A / m ^ 2 millisecond, the film thickness and particle sizes can reach values ​​less than micron scale.
