  • Increase of system effectiveness of two - stage transportation: on an example of management of a solid municipal waste

    The model of increase of efficiency of the created system of transportation of a municipal waste is presented. Need for carrying out modeling and the actions connected with reorganization of system, because of possible increase in total expenses is proved at shift of positions of reloading stations of rather optimum points owing to local conditions of the territory of municipality.

    Keywords: a solid municipal waste, technological process of transportation, two - stage transportation

  • Use of an inversion multidimensional classification in conceptual design

      The article is devoted to the methodology of construction of fields of knowledge through the use of procedures inversion, allowing to most fully present the essence of the studied object, its inner content, expressed as a unity of diversity contradictory properties ensuring its integrity required for the generation of new knowledge as an increase to the number of criteria for the classification and, accordingly, the space of the classification.

  • Rheology salt massif with a spherical cavity

    This article is related to technological problems of cavities with kamufletnyh explosions, during which the temperature in the cavity greatly exceeds the initial temperature of the array. Often these cavities are created in an array of rock salt. Because the salt even at light loads demonstrate expressive flow properties, it is interesting solution to the problem of creep salt massif with a cavity under the action of a force (pressure inside the cavity and the pressure of the soil), and thermal loads.

  • Tools to support the modeling process, which is based on L-systems

    It is proposed software-technological complex for modeling, which uses L-systems (Lindenmayer Systems) as the tools of modeling and visualization. The main purpose is to construct models of processes and structures that have a fractal nature. The complex supports different types of L-systems: deterministic context-free L-systems, stochastic L-systems, parametric L-systems, context sensitive L-systems. The developed tools have been used to model and analyze the socio-economic processes.

  • About kinetics of heat irradiation in mixing and solidification of astringent

    Knowledge of the kinetics heat irradiation give more sources for understanding physico-chemical process connected with solidification astringent. On curves of heat irradiation you can traced three stage and then read the kinetic equations describing each of them.

    Keywords: kinetics, heat irradiation, speed, stages, astringent

  • Search of optimum location of stations of an overload solid municipal waste mathematical methods

    In article the technique of optimization of placement of waste reloading stations, allowing to define both location, and number of stations that allows to reduce both operational and capital expenditure for the organization and functioning of system of the address with a waste is offered.

    Keywords: technological process of transportation, a solid municipal waste, critical distance

  • Problems of education and a culture of student health

      Main areas of modern human life and society (education, work, leisure) require the application of complex human ¬ lovecheskih forces and capabilities - physical, psychological, emotional ¬ tional, intellectual, and spiritual. Difficult transition to a market economy in 90 years, affected the fitness and sports motion, ¬. Socio-economic factors and conditions were the prerequisite for the formation of unhealthy motivations some part of students and the students, and this has a negative impact on their health and physical fitness.

    Keywords: Education, training, rehabilitation, and social disease caused by the problem of professional personnel, college environment, culture, science, intellectual work and the result of labor

  • Anomalous electron emission in the soft X-ray irradiation of the surface of electrets

     Theoretical model of anomalous electron emission has built for an soft x-ray irradiation of  surface elektrets, explaining the different character of correlation between energy and emission intensity of ferroelectric  solid solution PbTiO3 - CaTiO3 and nonferroelectric  ceramics CaTiO3.  Shown that  due electret surface irradiation the  Schottky area is  depleted by nonequilibrium charge carriers.

    Keywords: Emission, electret, ferroelectricity, Schottky area

  • Mathematical representation of the characteristics of the interphase boundary surface of the transition layer

    It is shown that to describe the phenomena and processes in a transition interfacial layer having a certain thickness, it is useful to distinguish the boundary layer of the surface and boundary diffusion layer, which lies entirely in the less condensed phase related. In accordance with this energy and power characteristics of the transition layer should be attributed to the boundary surface of the interphase transition layer. The basic equation of electro capillary boundary of the surface layer, establishing the dependence of the surface tension of this layer on the chemical composition of the second phase, and bordering the jump of electric potential between them.

  • The passive wireless sensor on surface acoustic waves for measurement of gas and liquid environments parameters

    The sensor design on surface acoustic waves (SAW), representing the delay line with unidirectional inter-digital transducers (IDT) is considered. The factor of reflection of SAW from the unidirectional IDT loaded on impedance depending on value of resistance connected to it is investigated.
