All rubrics
Release: 2016-2 (14)
Keywords: integral transforms, operator, bilinear system of integral equations, uniqueness theorems
Annotation: 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
On the cubature formula with the involving derivatives
Release: 2016-2 (14)
Keywords: cubature formula, Sobolev function spaces
Annotation: The algorithm of replacing some other lattice nodes to minimize the error functional norm is developed under the concordance condition of the convergence order with lattice step and the smoothness of the function along the selected coordinate directions. The results obtained by the method tested in the control examples
Dynamics of fluid mixed layer penetration in 3d calculations
Release: 2016-2 (14)
Keywords: three-dimensional numerical simulation, turbulent closure, mixed layer penetration
Annotation: The wind-influenced deepening of the mixed layer in a stratified rectangular reservoir has been calculated using three-dimensional numerical model. A comparison of results has been made for various turbulence models
Simulation-based verification of logical descriptions with functional indeterminacy
Release: 2016-2 (14)
Keywords: automation of design, verification, simulation
Annotation: 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
Seasonal dynamics of Shira lake currents by field observations in 2014-2015 years
Release: 2016-2 (14)
Keywords: dynamics of wind current, spectral analysis
Annotation: In the article the variability of wind currents on the lake Shira was analyzed in period 2014-2015 years based on the data of field observations. The spectral analysis of internal waves, caused by variable wind, was carried out
