This approach was used in a series of space experiments conducted by specialists of Center for Robotics and Technical Cybernetics and SPbGPU. To describe the network infrastructure we propose to use a hierarchical approach which allows to distinguish three levels of information interaction processes between network objects, particularly onsurface robots and human operator. In the paper is proposed the second mesoscopic level that describes informational transmission processes associated with the formation of virtual connections with the desired level of quality of service, in particular the packet delay values to ensure the telepresence of operator in zone operations. 004.77 remote control network-centric principles transport network infrastructure dynamic adaptation force-torque feedback https://infocom.spbstu.ru/article/2013.36.2/ 2_zaborovsky.pdf

This model realizes communications between different economic agents and is based on the Leontyev’s static intersectoral balance. Communications appear to be the basis of economic and social systems. Starting with the set of modeled microprocesses (behavior of individual agents) we have an opportunity to observe the states of the macroprocess – the behavior of economic system in a whole. While experiments with the model valuable results were received. These results are connected with economic system behavior under the conditions of enough money funds and their lack. 004.94 modelling agent-based model communications Leontyev’s intersectoral balance NetLogo modelling framework statistical analysis https://infocom.spbstu.ru/article/2013.36.9/ 9_zvereva.pdf

The approach is based on the use of the Pugachev–Sveshnikov equation for the characteristic function and its reduction to the parametric Riemann Boundary Value Problem for bi-half planes. The Crandall's problem for the controlled dry friction, which is switched off when body's velocity is over a critical level, is solved as an instance of application of the derived theory. The asymptotic behavior of the displacement of a body, placed on a randomly oscillating foundation, and occupation time, while velocity is under the critical level, are explored. 519.217.4 continuous Markov process Pugachev–Sveshnikov equation Riemann boundary value problem for bi-half planes stochastic mechanics Crandall's problem Feller's problem dry friction https://infocom.spbstu.ru/article/2013.36.10/ 10_zayats.pdf

This is based on a joint digital processing of the input short pulse signal and a corresponding output. In order to measure the frequency response function, a short current pulse is applied to the shunt input; input and output signals of the shunt are recorded in a digital  scilloscope memory; then spectra of these two signals are computed. Amplitude and phase responses are determined by the arithmetic ratio of spectral components of the input and output signals at appropriate frequencies. 621.398.725:621.317.727.1 PULSE CURRENT SOURCE CURRENT SHUNT DYNAMIC BEHAVIOUR TESTING AUTOMATION https://infocom.spbstu.ru/article/2013.36.11/ 11_zarevich.pdf

We propose a multiagent genetic optimization method implementing different decision searching strategies, including a simulation module. The comparison of the different scheduling methods has shown: firstly, the unsuitability of the MS Project planning method to solve the formulated problem; and secondly, both the advantage of the multiagent genetic optimization method in terms of economic effect and disadvantage in terms of performance.
