    [article]
    Summary

    Based of scaling of random walks a computer model of multistage processes of porous cluster formation in crystalline matrix was created. A package of computer programs was elaborated that simulate dynamical processes of cluster formation into the depth of crystals tacking into account the processes, that occur on a surface, applied external fields as well as chemical reactions, that accompany these processes. Morphological features of pores formed were compared with regularities that were connected with current-voltage characteristics shape for anodization process…

    Summary

    Mathematic model of spreading of blowing wave in straight linear processing of coal mine with considering spreading of combustion front by coal dust formed from the walls of mine by gas stream moving after the front of blow wave has been made. Carried out evaluations showed that combustion of coal dust can raise pressure on its front. Analysis of influence of local deposits of coal dust combustion on the pressure on front of blowing wave have been carried out.

    [article]
    Summary

    In work the results of computer modeling of heteroannihilation interactions in systems with cluster distribution of donor molecules and initial distribution of acceptor molecules are presented. In the course of conducted researches it is established that comparative temperature changes of kinetics of heteroannihilation at cluster distribution of donor molecules are described by simple linear dependence with quenching temperature coefficient k depending from topology of clusters formed on the surface and inversely proportional to cluster’s size.

    [article]
    Summary

    The growing field of sensor research has infused virtually all professional communities in science and engineering. The scope of applications encompassed by sensing technologies is extensive and spans from critical care through industrial process control to defense and homeland security. We propose to address several outstanding problems of chemical agent detection by means of a small-size optical sensor. The core of our approach is the development of a novel optical sensing technology to identify specific toxins by recognizing their spectral absorption characteristics. While the principle of operation of our sensor is based on interference refractometry used in other high-precision detection and measurement devices, two major innovations include the application of holography to compensate for any imperfections of inexpensive optics and make our device simpler and cheaper, and also targeting specific regions of the optical spectrum, where nonlinear resonant response indicates the presence of specific toxins. High sensitivity and selectivity can be assured by the physical nature of detection and by advanced processing of the optical data. In this paper, we discuss the approach and present a MATLAB simulation study.
