    Return the one-dimensional problem with an unknown source
    Author: Schabanowa Galina Ivanovna
    Description:  Investigated the one-dimensional inverse problem with an unknown source and an unknown variable coefficient two known solutions at fixed points in the plane. Inverse problem using the method of integral transforms is reduced to inverse problem of Sturm-Liouville problem. The uniqueness theorems are proved

    Numerical modeling of two-phase flows in microchannels
    Author: Shebeleva Anna Andreevna / Minakov Andrey Viktorovich
    Description:  Results of testing methodology for calculating two-phase flows based on the method of fluid in the cells (VOF method), in the microchannel are considered in this work. Numerical results are compared with experimental data. It has been shown that the value of the contact angle plays a key role in the description of two-phase flow in microchannels
    Keywords:  VOF-method, two-phase flows, the contact angle

    Simulation-based verification of logical descriptions with functional indeterminacy
    Author: Cheremisinova Liudmila Dmitrievna
    Description:  The problem of verification of logical descriptions of combinational networks is considered for the case when the initial functional description of the network under design has indeterminacy. The proposed verification approach is based on simulation of еру network functionality for the general case when input stimuli are represented by ternary vectors

    A parallel semi-Lagragian algorithm for advection equation
    Author: Vyatkin Alexander Vladimirovich / Kuchunova Helen Vladimirovna
    Description:  We construct the algorithm of the family of semi-Lagrangian methods for an advection problem. The algorithm is based on the integral balance equation for the neighborhood of a grid node. This equation involves integrals over two neighboring time levels. We study the effectiveness of the parallel algorithm with OpenMP technology
