  • Zone electrophoresis. Numerical-analytical method for solving of applied problems in partial derivatives of first order

    Numerical-analytical solution of the problem of multicomponent mixture fractionation under action an electric field is constructed. This problem is known as the problem of zonal electrophoresis which extensively used in chemistry, medicine, and biology. Problem is reduced to study of the Cauchy problem for systems of hyperbolic type quasilinear equations in partial derivatives of first order. The proposed method is based on a generalized hodograph method, which allows obtaining an analytical solution of the problem in implicit form. Explicit form of the solution is recovered using the transformation of the Cauchy problem for system of quasilinear hyperbolic equations to the Cauchy problem for a system of ordinary differential equations that are solved numerically.

  • Construction of a physical model of the process of air pollution for cement plants

    The article analyzes the state of urban air. It proved the impact of cement industry on air quality. The article also analyzed the technological process of cement production. As a result, built carrying circuit material flows. Carrying circuit material flows determined that dust is highly polluting air environment, because the dust is released at each stage of production. Analysis of the cement production process has allowed to identify the main objects that are involved in the process of air pollution, as well as to establish their relationship. The result is a physical model of the process of air pollution. Further, on the basis of a physical model of the process of pollution, it is possible to construct a physical model of the process of reduction of air pollution.

  • Method of the statistical analysis of characteristics entrance streams of inquiries in systems of information processing

    Receiving adequate mathematical model requires studying of streams of inquiries into the information system which are described as random variables. The purpose of the analysis is definition of density function of distribution of random variables - time intervals between inquiries of users. The offered method contains stages at which check of independence and similarity of distribution of random variables is carried out, stationarities of a stream and the law of distribution of intervals of time between events is defined. For check of independence and similarity of distribution of random variables the criterias based on selective coefficients of correlation and the criteria which are based on the spectral density of intervals are used. For the analysis of stationarity of a stream of inquiries the standard methods of the smallest square regression and methods based on the analysis of special mathematical models are used. For example, Poisson's stream which parameter changes under some law is supposed. Sequences of the events displaced by casual influences are presented as the events happening according to the schedule with delays in the form of the independent and equally distributed random variables. For comparison of intensity of streams of inquiries from various users of information system the criterion based on the relation of function of maximum similarity and an index of dispersion is used. The offered technique is focused on using of the modern computer programs, for example, MatLab, Statistika.
