Return the one-dimensional problem with an unknown source

Page:387-394

Release: 2016-2 (14)

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

Page:400-404

Release: 2016-2 (14)

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

Page:404-409

Release: 2016-2 (14)

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

Page:409-416

Release: 2016-2 (14)

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

Page:417-423

Release: 2016-2 (14)

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
