Arbitrary Lagrangian–Eulerian formulation for fluid–rigid body interaction

Improved Formulation for Geometric Properties of Arbitrary Polyhedra

TECHNICALNOTES are shortmanuscripts describing new developments or important results of a preliminary nature. These Notes cannot exceed 6 manuscript pages and 3 Ž gures; a page of text may be substituted for a Ž gure and vice versa. After informal review by the editors, they may be published within a few months of the date of receipt. Style requirements are the same as for regular contributions...

Dynamic Fracture Analysis Using an Uncoupled Arbitrary Lagrangian Eulerian Finite Element Formulation

This paper deals with the implementation of an efficient Arbitrary Lagrangian Eulerian (ALE) formulation for the three dimensional finite element modeling of mode I self-similar dynamic fracture process. Contrary to the remeshing technique, the presented algorithm can continuously advance the crack with the one mesh topology. The uncoupled approach is employed to treat the equations. So, each t...

An Algebraic, Energy Conserving Formulation of Classical Molecular and Newtonian «body Interaction

Wigner formulation of optical processing with light of arbitrary coherence.

A unified mathematical formulation for designing and analyzing even the most general optical processor is presented. It exploits the Wigner distribution function to characterize the illumination, the input, the inherent filter, and the output results. To characterize the propagation of the light through the optical processor setup, we exploit the Wigner matrix formalism, which is appealing beca...

A Framework for Gaze-Driven Interaction in Arbitrary Environments

The excellence cluster CoTeSys – Cognition for Technical Systems – addresses most diverse scenarios with different kinds of interactions between humans and machines. For most of these scenarios, human gaze is a very important cue to get information concerning the user’s intentions, current mental state, etc. To get this data the framework consisting of a highly accurate head-mounted gaze tracke...
