    The question of increase of efficiency of the cooling process in the compression refrigerating machines and household refrigerating appliances. Describes a new original method of cooling of the condenser vapour-compression refrigeration machines, which is due to wet the surface of the capacitor with its further blow. Shows the complexity of the theoretical analysis of the proposed method of cooling and substantiated the necessity of experimental studies of the process of cooling of the refrigerant in the capacitor. 

    Keywords: compression refrigerator, evaporative a capacitor, a new method of cooling refrigerant, energy performance, the efficiency of the cooling

  • The reasons of occurrence of interval values in mathematical models of robust research the stability of control systems

    Examines the historical stages in the development  of the theory of systems research management of the uncertainties, the reasons for they arise in the mathematical  model, this is reflected in an interval values in the transfer  function of the object of control. It is proposed algorithm for obtaining experimentally the interval of values.

    Keywords: interval values, robust stability, the transfer function, parametric uncertainty, a mathematical model of the management system

  • Mathematical modeling of the process in Eshkakon storage reservoir and its practical significance

    The mathematical model of storage reservoir has been deduced. The deposition rate of particles in reservoir has been calculated. It is concluded that storage reservoir is a preliminary sedimentation tank.

  • Research of features of influence of transport factors on ekologo-economic safety of the country

    Article is devoted to justification of approaches to research of influence of transport factors on ekologo-economic safety of the country on an example of railway transport. A basis of research is the system approach. The environmental management system on railway transport is offered for considering as set of the objects of railway transport interconnected and mutually influencing at each other and environment elements. Approaches to development of strategy of development of system of environmental management on railway transport and the directions of protection and improvement of a state of environment for service conditions of objects of a regional subsystem of railway transport are proved.

    Keywords: ekologo-economic safety, railway transport, model, strategy, environment, system approach

      The article contains geometric and computer simulation of helical surface corner cutter. When the geometric modeling shows how to get the analytical dependences for determination of envelope surface collection features both display the hyper surface in the hyper plane. Shows the polygonal model envelope and one of the sections of hyper surface. Computer solid modeling process forming opportunity of obtaining models srezaemyh layers and their quality characteristics.

  • 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.

  • Modeling and analysis of the demand for new transport network improving objects

    When introducing a new facility to improve the transport network, there are appear many risks. The priority is the financial riskbecause core funding for these projects comes from private organizations. Careful calculation of demand is an integral part of the development project. For the effective analysis of the transport network since the project requires a conscientious approach to the latest technology.

  • 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.
