  • Roundwood as a subject of labour in the process of group barkingRoundwood as a subject of labour in the process of group barking

    Research results of roundwood with the bark as a subject of labour in the process of barking are provided in the article. The numerical values of such physical and mechanical properties of the bark like conditional shear tensile strength of the bark at cambial layer are ascertained.

    Keywords: Woodwork, bark, timber, barking, physical and mechanical properties

  • Modifications of BM25 using a genetic algorithm

    The rapidly growing information space combined area networks creates new needs for management, reporting, and especially in the search for data. On the first place there is the criterion of relevance, which allows for its correct use to increase the efficiency of information retrieval. There is a fairly large number of schemes and models for solving search problems, one of which is the BM25.

    Keywords: genetic algorithm, information retrieval, modification BM25

  • Passive pressure sensor based on surface acoustic waves

      Proposed to use a sensor based on surface acoustic wave (SAW), which represents a delay line with unidirectional interdigital transducers (IDT) for measuring the pressure in the liquid. Reflective IDT loaded by series connected inductor and two capacities. One of these capacities - this trimmer, and another - a membrane capacitor whose capacitance depends on the pressure. When the pressure changes of the membrane capacitance capacitor, which changes the reflectivity of the reflective IDT. The magnitude of changes in this ratio determines the pressure applied to the membrane capacity.

  • Problem analysis of navigation in portable scientific data representation

      Article describes actual problems of personal navigation in portable scientific document set representation. Proposed algorithm for ranking document graph paths based on machine learning, described algorithm analysis and most probable navigation context parts.

    Keywords: Document set navigation, machine learning, navigation context, scientific data visualization

  • Research dimensional stability of base polymer materials for advanced printed circuit boards

    Considers and researches dimensional stability advanced base polyimide materials for high-density PCB.

  • Psychosemantical analysis of perception the political order in a stressful condition

    This paper focuses on defining the elements forming the political tension - on the emotional component of a group of political attitude. Baseline data were obtained by questionnaire. All were interviewed 66 patients. Respondents were asked to rate 20 attributes-antonyms two "ideal", positive and negative political orders. And two real order: in Region and in Russia as a whole. It is shown that the investigated audience is characterized by low political activity, and the activity of the emotional perception of the existing orders of magnitude higher than the perception of ideal constructs. An unexpected result of a negative perception of the political order in Russia in a whole, the local order in due permanent stressful situation for the given audience. People normally (or neutral) treat policy which always acts them through region policy. And of the troubles accuse (probably unconsciously) change of a political system which associates at them with center policy.

  • The integrated cognitive architectureof models of sicial systems

      The article deals with the scientific principles of modern cognitive modeling offered in foreign practice to combine already existing and new models in the future in the form of cognitive architectures. Our approach is based on the concept of a unified theory of cognition, described by Alan Newell, which offers the general provisions for cognitive models used in all areas. In the computer environment, the theory is realized in the form of cognitive architectures. Shown, cognitive architecture is a system integration of static and behavioral models, which provides a solid approach to modeling knowledge of social processes, from the empirical data to quantify the simulation  of results, from level of the neural description to system level, thus the cognitive model is scaled to higher level with preservation of qualitative properties, and as a platform for integration the storage of data serves. Formally described by the level of integration corresponds to the construction of integrated information environment that combines unified storage of data with appendices of analytics.

  • Infrastructure model of a cultural complex

      It is shown that the simulation as part of the cultural complex social simulation developed within the general methodological trends inherent in sociology as a whole. To study the possibilities and patterns of cultural complex of the Rostov region (for example cultural complex in Rostov-on-Don), as a complex socio-economic system is the most productive synthesis of systems analysis, simulation of socio-economic processes and mapping method. The model, built with the help of a simulation tool AnyLogic 6, there are two levels of sub-system: the level of the model with a high degree of abstraction to model the interaction of people and the cultural infrastructure of the region - for implementation using multi-agent approach and the level of the model with an average level of abstraction for simulations Queuing (cultural needs of the population) at cultural complex. Based on the data obtained in the course of the experiment the number of dissatisfied cultural infrastructure remains about the same - about 16-17% of the total number of residents who use the cultural complex.

  • Investigation of influence of adsorbtion of CO on characteristics of hold-up line on SAW with ZnO nanorods sensitive element

    Structure of  surface acoustic waves(SAW) of CO sensor was developed. SAW sensor include transceiving IDT and catoptric IDT, which is loaded on the impedance of ZnO nanorods. Peak of reflection SAW from IDT clearly observed as result Fourier transformation of time function of pulsed response. IDT loaded on resistance paralleled ZnO nanorods, which depends on the concentration of CO.
