PublicationРасчет изгибаемых плит на действие сосредоточенной силы;( 2019)Для расчета сосредоточенной силы при расчете изгибаемых плит используются обобщенные уравнения метода конечных разностей (MKP). Применение обобщенного уравнения МКР дает нам больше возможностей для учета разрыва искомой функции, а также ее первых двух производных. Обобщенные уравнения МКР является новым направлением исследований в области структурного анализа. Наряду с другими методами принесет много вариантов для инженеров, которые работают в области структурного проектирования и расчета.

PublicationDensity deconvolution from grouped data with additive errors( 2019)We study the problem of estimating a density based on grouped data with additive errors. We propose a consistent estimator for the density and compute upper bounds on convergence rate of L2-risk in some cases of error density.

PublicationMining Stock Market Time Series and Modeling Stock Price Crash Using a Pretopological Framework.( 2019)We introduce a computational framework, namely a pretopological construct, for mining time series of stock prices in a financial market in order to expand a set of stocks by adding outside stocks whose average correlations with the inside are above a threshold. The threshold is considered as a function of the set’s size to verify the effect of group impact in a financial crisis. The efficiency of this approach is tested by a consecutive expansion process started from a single stock of Merrill Lynch & Co., which had a large influence in the United State market during the studying time. We found that the ability to imitate the real diffusion process can be classified into three cases according to the value of \( \theta \) - a scaling constant of the threshold function. Finally, the process using pretopological framework is compared to a classical one, the minimum spanning tree of the corresponding stock network, showing its pertinence.

PublicationWeighted Lebesgue and Central Morrey Estimates for P adic Multilinear Hausdorff operators and Its Commutators( 2019)In this paper, we establish the sharp boundedness of p-adic multilinear Hausdorff operators on the product of Lebesgue and central Morrey spaces associated with both power weights andMuckenhoupt weights. Moreover, the boundedness for the commutators of p-adic multilinear Hausdorff operators on the such spaces with symbols in central BMO space is also obtained.
