  • 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.  

    Keywords: double-gap cavity, electrodynamic parameters, mathematical simulation, resonance frequency, characteristic impedance, method of planned experiment

  • The vibrations of multilayered half plane with relatively much sunken cavity of arbitrary shape

    The solution of vibration problem for multilayered half plane with cavity of arbitrary shape is constructed using boundary element method. For the case of relatively much sunken cavity an asymptotic representations for fundamental solutions is used. The results of problem simulation for displacement and stress fields close to cavity surface are given using boundary element method

    Keywords: multilayered environment, cavity of arbitrary shape, asymptotic analysis, boundary element method

  • The interconnected control system of heating and ventilation installations in the protected ground

    Consider the use of management system of heating and ventilation plants in greenhouses, uniform distribution of heat and humidity in the area of biological objects, the use of an improved system of management regimes of the microclimate in the protected ground on the basis of programmable smart relays

    Keywords: power consumption, temperature-humidity conditions, microclimate

  • Research of process of wettability of pulverulent potassium chloride containing the admixtures of flotoreagents

    The express-method of estimate of the rate of wetting  of pulverulent powder of KCl is developed. The wettability of potassium chloride powder containing the admixtures of flotoreagents by solutions of different binders is studied.

  • Principles of metrology information-measuring systems for analytical measurements in biomedicine

      Regarding the structural evaluation of the instrumental error of bio MIS tool software package was developed that allows to take into account the error in the analysis of clinical diagnostic measurement in hematology research. It allows to analyze the results of hematological measurements with the measurement error and issue you with a message that characterizes getting results within normal or unreliability. Nanoparticles in biomedical analytical measurements are used as contrast agents, since, being immobilized specific proteins with adhesion to the diseased cells and bacteria. Register ultrasonic signal produced when the laser blood flow to the entered nanoparticles allows the detection and enumeration of diseased cells. The block diagram of analytical studies was designed to prove its basic metrological characteristics. Research is conducted in the centers for collective use of the Southern Federal University "Nanotechnology" and "Laser Technology", equipped with modern and unique nanotechnology research equipment.

    Keywords: Bio MIS, nanoparticles, hematological measurements

  • Diagnosis of psychophysiological and emotional state of the human operator

      Various non-invasive assessment of psycho-physiological and emotional state were analyzed: the fractal estimation of speech signals, the analysis of rhythmic EEG patterns and computer stabilometry. The results allowing  prediction of the transition of the individual in a particular state, were obtained and objective criteria for determining the individual personality as a specialist were identified.

    Keywords: Emotuonal speech, EEG pattern, attractor, suggestibility

  • Cognitive approach to the research of geopolitical processes in world regions and cognitive modeling of their development (On the example of the Black – Caspian Region)

      The article is devoted to the problem of the research of geopolitical processes on the world regions’ scale under present-day conditions. The article substantiates the necessity of their analysis with the help of the cognitive approach as an effective means of cognition of the interconnections and interrelationships within the complicated systems. With that aim in view the specifics and the stages of the cognitive modeling are given thorough analysis in the article. This type of modeling is adapted to the analysis of geopolitical dynamics on the regional/sub regional level taking into consideration its aptitudes to make prognostic scenarios of the development of the situation. The possibilities of the cognitive modeling of geopolitical processes are illustrated on the example of the situation in three sub regions constituting one (big) the Black Sea – Caspian region.

    Keywords: World regions, geopolitical processes, modeling of the complicated systems, modeling of the geopolitical processes, cognitive modeling, the program’s system of the cognitive modeling, the Black Sea – Caspian Region, the Black Sea sub region, the Caucasus

  • The formation and evaluation of development of the market of real estate services and real estate in the region

    In the article in detail the analysis of processes of formation and development of the market of real estate services and real estate in the region. Using methods of statistical analysis and methods of logical-functional approach was built factor functional model defines the dependence of prices at the market of residential real estate from the regional peculiarities and the level of welfare of the population, as well as the performance of the construction industry, which allowed us to forecast of the price of the status of the real estate market of the Stavropol region in the medium term and to strengthen routine component in the activity of the real estate organizations.
