  • The practice of database formation for live monitoring university's development activity indices and it's rating growth

    We examine database formation that reflects university's development activity indices and it's rating improvement - for this we use the system developed for the Southern Federal University. The task of choosing a multiparametric DBMS is described. Entity-relationship model as a tool for database conceptual design is built. The database of formation and processing process is also modelled, for this we use the UML notation activity diagram.

    Keywords: development activity indices, rating impovement, DBMS (database management system), Entity-relationship model, UML, activity diagram

  • Biomonitoring of environmental genotoxicity of Rostov-on-Don with Pylaisia ​​polyantha

    To assess the genotoxicity of environmental urban ecosystems appropriate to use indicators geno-and cytotoxic extract pilezii Multiflora. Geno-and cytotoxicity of the extract can be assessed by the level of chromosomal aberrations, as well as indicators of the mitotic index in the root meristem of pea, germinated on an extract pilezii Multiflora. When using indicators geno-and cytotoxicity in urban ecosystems should talk about the genotoxicity of the environment in the case of a statistically significant difference from the control of these parameters.

  • Experimental research of silicon detector current pulse processing electronic module

    Measurement results of basic characteristics of electronic module based on two specialized analog integrated circuits depending on different square area silicon detectors using source of 239Pu alpha particles is given. Processing of current pulses typically consists to convert them into a voltage by charge sensitive amplifiers and reduce noise by bandpass filters. Earlier for work with avalanche photodiode we have developed, constructed and tested two electronic modules "CRP-MDL-1" and "CRP-MDL-2". During the measurements was investigated spectrometric channel response on exposure to ionizing radiation from a source of alpha particles 239Pu and test input signals, thus we determined basic technical characteristics including energy resolution and noise characteristics. As a result, research found, that the output signal has the following timings: rise time - 1 us (levels of 0.1-0.9), peak time - 1.4 us, fall time - 1.8 us pulse width - 3.5 us. The conversion factor of module working with silicon detector (area of ​​1000 mm2 and a capacity 500 pF) consists about 10.6 mV / fC, or 0.47 V / MeV. Integral nonlinearity of spectrometer path is not worse 0.4% in the range from about 0.1 to 3.2 V. The energy resolution was 89.1 keV line of 5157 keV. The experimental studies revealed that using an external low-noise transistors developed module can be used in the construction of standard radiometric paths. It is appropriate to use the developed design-circuit solutions for implementing 4-channel chip for multi-channel radiometric and spectrometric systems.

  • On about the features of UAV control systems with flapping wing

    In the article a number of approaches to a flapping wing pilotless vehicle control system synthesis are analyzed. Referred type of pilotless vehicles is possessed of a number of advantages compared to the traditional schemes, but requires a special approach to control system creation because of strong nonlinearity and multicoupling of a controlling object mathematical model. As a result of a control system synthesis approaches analysis a synergetic approach was marked out as the most adequate for the mentioned above type of controlling objects. An idea of prognostics application for the goal of reaching of adaptive control is also set forth. In this case parameters of an object of control and parameters of ambient both are to be forecasted whereby an adaptive behavior of an object of control is expected to be achieved.

  • The loosely coupled algorithm of integrated INS-GPS navigation system of the vehicle

    The existing approaches to the integration of relatively cheap strapdown inertial navigation system (SINS) based on MEMS-based technology and satellite navigation systems (SNS) are ineffective in relation to motor vehicles. We consider the iterative algorithm for the loosely coupled mode of integration of heterogeneous navigation systems do not intend to use the optimal estimation. The solution is obtained on the basis of the fully nonlinear model of the navigation system of the vehicle and the, therefore, is valid for arbitrary and unknown in advance nature of his movements, and, in the most general assumptions about the level of disturbances acting upon him.

  • Simulation of failures and their elimination on financial markets with the events flow generated by a binary tree

    A financial market on a stochastic basis with a filtration generated by the binary tree is considered. A plugin simulating failures on this market is constructed. We mean by a failure the following situation on the financial market: when passing from a time moment  to the next one new events arise but discounted price of the fixed type stock does not change. A failure generates the incompleteness of the market (the set of martingale measures of this market is infinite). By modelling of a weak deformation it is possible to reduce the set of martingale measures to a unique measure. Thereby the price of every contingent claim is uniquely determined. This price may be considered as "fair price".

    Keywords: Stochastic basis, probability measure, financial market, binary tree, arbitrage free, completeness, weak deformation, martingale measure, plugin.

  • Modeling of electrodynamic parameters of a multi-mode double-gap cavity for using in miniaturized multi-beam klystron’s devices

    For miniaturized vacuum klystron type devices utilization of a double- gap strip-line cavity with suspended ceramic substrate is very promising. 
    The two-mode operating mode of such cavities practically isn't studied enough; so there is the great scientific and practical interest for research of electrodynamic characteristics of cavities during multi-mode operation that correspond to simultaneous excitement of anti-phase and co-phase modes in a double gap.  
    In this article results of the 3-D numerical modeling by means of the Ansoft HFSS code are presented, and also the experimental results of the electrodynamic properties of the half-wave double- gap cavity with the suspended ceramic substrate are submitted. Optimum parameters of this design, allowing to carry out simultaneous excitement at multiple frequencies with frequency rate (K=2) are determined.
    In such cavity high values of unloaded Q factors isn’t need because dielectric losses and conductor losses can be compensated at the expense of  the negative electronic conductivity that brought by modulated electronic beam. The operating mode with frequency rate   can be used for increasing of efficiency of generating and amplifying micro devices with filament cathode and matrix field emission cathodes.

  • The algorithm for constructing the trajectories of moving objects in a video based on optical flow

    At present, the development of algorithms is particularly relevant high-level analysis of video sequences, including tracking of objects in a video stream and their implementation in information and communication systems. In the proposed approach the pretreatment step uses optical flow calculation for each frame video sequence, as well as low-level features (such as a representation of each pixel in the color space YIU). For moving objects optical flow is more important than for a stationary background and allows you to find the foreground objects in video sequences and adjust the weighting function in determining the histogram similar to the adjacent frames, taking into account the motion of objects.
