Coupling of Finite and Boundary Elements for Transient Eddy Current Problems
Advances in Electrical and Electronic Engineering, 2017 A symmetric coupling of methods of finite and boundary elements for numerical solution of transient eddy current problems is described. This is an essential step in modelling of electromagnetic forming of metalic sheets.

Microprocessor-based Finite Elements Solutions to Marine Aerosol Deposition Models
, 1994 Simple finite elements for an aerosol deposition model embryo are presented. The model is derived by studying concentration changes due to effects of relative humidity (rh), gravitational settling and eddy transport. Its uses a discretisation of particle

On the p-Elements of a Finite Group [PDF]
Proceedings of the American Mathematical Society, 1975 Let G be a finite group, p a prime, and x a p-element in G. An element g in G is called a witness of G if the subgroup generated by x and g is a p-group. The set of all witnesses of x in G is denoted by W(x). This paper shows that x belongs to a given Sylow p-subgroup P of G if one of the following holds: (1) G is p-solvable and W(x) Pfl n Ixgg E GI ...

A Q‐Learning Algorithm to Solve the Two‐Player Zero‐Sum Game Problem for Nonlinear Systems
International Journal of Adaptive Control and Signal Processing, Volume 39, Issue 3, Page 566-581, March 2025.A Q‐learning algorithm to solve the two‐player zero‐sum game problem for nonlinear systems. ABSTRACT This paper deals with the two‐player zero‐sum game problem, which is a bounded L2$$ {L}_2 $$‐gain robust control problem. Finding an analytical solution to the complex Hamilton‐Jacobi‐Issacs (HJI) equation is a challenging task.

Conforming finite element methods for the clamped plate problem
, 1975 Finite element methods for solving biharmonic boundary value problems are considered. The particular problem discussed is that of a clamped thin plate. This problem is reformulated in a weak, form in the Sobolev space Techniques for setting up conforming

The Trefftz finite elements modelling crack propagation
Computer Assisted Methods in Engineering and Science, 2022 Investigation of crack propagation can sometimes be a crucial stage of engineering analysis. The T–element method presented in this work is a convenient tool to deal with it.

Modelling in Science Education and Learning, 2013 The mathematical model's validity used in computer programs are based on a specific formula implemented leading commercial software. Since these programs use their own databases of materials sometimes the question arises of what the miscalculation in ...
