Internal interfaces in a domain could exist as material defect or they can appear due to propagations of cracks. Discretization such geometries and solution the contact problem on internal be computationally challenging. We employ an unfitted Finite Element (FE) framework for discretization domains develop tailored, globally convergent, efficient multigrid method solving problems interfaces. In...

This thesis investigates the necessity for, feasibility and construction of non-visual user interfaces to improve computer access for the visually impaired. The senses of hearing and touch are both appropriate for non-visual human-computer interaction, and this report presents and analyses different ways to use these senses to access a modern graphical user interface. A set of guidelines for th...

The coherent edge interface structures of the relatively thin {111}Al ? plates have been analyzed in a peak-aged Al-Cu-Mg-Ag alloy by atomic-resolution scanning transmission electron microscopy (STEM). Analysis STEM images showed that these interfaces can deviate from their orthogonal orientations to broad plate surfaces. tilts correlate with shear components appearing along surfaces and changi...

This paper deals with the representation of the trace of iterative Schwarz solutions at the interfaces of domain decomposition to approximate adaptively the interface error operator. This allows to build a cost-effectively accelerating of the convergence of the iterative method by extending to the vectorial case the Aitken’s accelerating convergence technique. The first representation is based ...
