  • Methods of determining the quality of a comprehensive assessment of complex technical systems in motor vehicles and material handling equipment

    The article describes one of the possible approaches to the investigation of a technique of definition of quality indicators of vehicles and lifting-transport machines, examines the concept - combining numerical estimate of single and complex indices into a single composite index.
    The following algorithms: the algorithm of finding the functional quality systems, represented by the linear form, with varying competence of experts, the algorithm modified method, allowing to make the transition from бифакторного distribution to мультифакторному, which is important when processing expert information; algorithm modified method, characterized by greater commonality and expanding the use of standard computer programmes at the decision of problems of estimation of quality systems on a computer.  

    Keywords: The level of quality of complex technical systems, decomposition methods of technical requirements, functional quality, modified method,algorithm

  • Recovery of impulse signals in cable lines

    The most effective solutions for recovery of impulse signals in dispersing cable lines can be perfomed on the base of heterojunction SiGe BiCMOS technology and are based on combining in one IC high-frequensy analog blocks on heterojunction bipolar transistors and control unit and adaptive correction of parameters on the base of CMOS transistors. Equalizer chip with adaptive correction of parameters provides hidh quality of recovery of signals with smallest costs for tuning and adjustment of cable lines.

    Keywords: equalizer, recovery of signals, heterojunction bipolar transistors

  • On the development of the wave theory of viruses

      We propose a model describing the motion of the wave of viruses inside and outside of living matter. It is shown that the Schrodinger equation can be used in the analysis of movement of the virus, as a physical material object in physical space. We calculated the de Broglie wavelength of the virus. The mechanism of viral diseases is shown as an interaction of genetic apparatus of human cells with the field structure of viruses. The concept of information-wave virus is given. The results of studies on patients with the use of information-wave of viruses, generated by a special generator of digital codes, are given. It is shown that the reliability of the mechanism of cell damage by wave digital information and viruses on the basis of vegetative resonance test. The reliability of the mechanism of cell damage by information-wave digital viruses is shown with the use vegetative resonance test. The conclusion that the suppression of viruses can be realized with the use of radiation from a special generator of numerical codes has been made.

  • Geo-ecological consequences of drawdown- suffusion processes

    The research of the proluvial and eluvial-diluvial loess-like loams with wide distribution in the Kuban plain was conducted. In this work the properties of the collapsible loess soils, which developed the processes that lead deformation of the engineering structures, violation of planning fields, to their water logging, etc, was considered. The analysis of subsidence processes, their origins and causes activation is provided. The link between subsidence and suffusion processes was conditioned. It is proved that the subsidence processes significantly affect the safety and population’s comfort living. The issues about the regime observations of these processes are raised.

    Keywords: Drawdown, suffusion, soil, loess material, geodynamics, geo-ecology.

  • The theoretical model of the laser excitation of acoustic signals in a liquid medium with the presence of nano-sized objects

      Now nanotechnologies are one of perspective methods of diagnostics in medical practice. Nanoparticles can be used as contrast agents for medical ultrasonic introscopy due to their adhesion to tumor cells and bacteria. The mathematical model of the laser excitation of acoustic signals in a liquid medium with the presence of the nanotubes was developed and numerically studied. Increasing of the level of photo acoustic signal was shown.

  • Methods of estimating the adequacy of simulation results

    This paper describes application of different criteria for estimating parameters of traffic simulation. For comparison following methods were used: statistical methods for comparison of a flow and speed in control points of a network - analysis of variance (ANOVA), Theil's U-statistics; relationships between flow, density and speed; relationships between trip time and stop time with using two-fluid models of traffic flow. For this aim we also used concept of meta-model. In order to implement this method we need on the first step to create separately relationship between traffic flow parameters for observation and simulation data and then to estimate combined model. The paper included results of calculation

  • Nested metagraphs as models of complex objects

    "The concept of the nested metagraph as the model of a complex object with different levels of generalization is introduced. It is shown that the nested metagraphs reflect the general system concept for description of complex objects with synergistic effect. This approach enables moving from the set-theoretic description of complex objects to their algebraic-theoretic description, thus increasing the model adequacy to real-life objects. The application of the nested metagraphs, in particular to business-intelligence and semantic search is considered. "
