It is well known that residual stresses and accumulated deformations during drawing processes can influence mechanical properties of the resulting products. This paper proposes the use of machine learning methods, such as artificial neural networks (ANN) and polynomial regression, to gain insight into the nature of these distributions across the cross-section of round wires. The ...

The effects of isothermal multidirectional forging (IMF) on the grain structure, second-phase particles of solidification origin, and dispersoids in the Al–4.9Mg–0.9Ni–0.9Fe–0.2Zr–0.1Sc alloy have been
investigated. The strain distribution over the sample volume during forging in a closed die has been analyzed
using a finite-element simulation. A method of considering the friction effect and changes in strain rate ...

For interpretation of electroencephalography (EEG) and magnetoencephalography (MEG) data, multiple solutions of the respective forward problems are needed. In this paper, we assess performance of the mixed-hybrid finite element method (MHFEM) applied to EEG and MEG modeling. The method provides an approximate potential and induced currents and results in a system with a positive semi-definite ...

Последние наблюдения, такие, как уменьшение напряженности магнитного поля, смещение магнитных полюсов и увеличение Южно-Атлантической аномалии, могут свидетельствовать о начале инверсии магнитного поля Земли. Согласно модели геомагнитного динамо, дипольная составляющая магнитного поля в момент инверсии обнулится и квадрупольная станет доминирующей. Для оценки возникновения радиационной опасности на поверхности Земли и в околоземном пространстве в момент инверсии магнитного ...

It is believed that microscopic life may exist in the subglacial ocean of Europa, a moon of Jupiter. However, the radiation belts of Jupiter complicate the possibility of its exposure on the surface or at shallow depths. Using numerical simulations, we investigated the influence of the tilt of the Jupiter magnetic dipole, the Alwen wings, ...

Tensile testing is widely used for the mechanical characterization of materials subjected to superplastic deformation. At the same time, it is known that the obtained flow data are affected by specimen geometry. Thus, they characterize the specimen rather than the material. This work provides the numerical analysis aimed to study how the material flow behavior ...

Objective: This paper develops a novel approach for fast and reliable reconstruction of EEG sources in MRI-based head models. Methods: The inverse EEG problem is reduced to the Cauchy problem for an elliptic partial-derivative equation. The problem is transformed into a regularized minimax problem, which is directly approximated in a finite-element space. The resulting numerical method is efficient and easy ...

Superplastic Forming is an industrial process to produce thin-walled products of complex shape. At the same time this process allows one to obtain the products with close to uniform thickness distribution. The process exploits the abilities of some polycrystalline materials to large elongations before failure. The best formability can be achieved only under very specific ...

Настоящая работа посвящена построению и первичному исследованию варианта модели «власть-общество» на основе стохастического клеточного автомата, описывающего динамику распределения власти в иерархии. Сформулированы лежащие в основе модели положения, проведена алгоритмизация и построена имитационная система, позволяющая проводить вычислительные эксперименты с моделью. Показано, что большая часть свойств детерминированной модели, имеющей вид системы дифференциальных уравнений, сохраняется в клеточно-автоматном варианте. ...

Free bulging process is an experimental technique which can be used to characterize a sheet material in conditions of biaxial tension during hot forming. Analytical and semi-analytical models of this process are usually based on the hypothesis offering certain relations between the geometrical characteristics of a bulge during forming. The paper presents an original relation ...
