Cavitation Bubble Dynamics inside Liquid Drops in Microgravity

Mohamed Farhat, Nicolas Dorsaz, Claude Nicollier, Danail Obreschkow, Philipp Kobel, Aurèle De Bosset

We report a fundamental study of single cavitation bubbles inside quasi-spherical water drops produced in microgravity (42nd ESA parabolic flight campaign, 8th ESA student parabolic flight campaign). High-speed imaging revealed implications of isolated, fi ...

A physical interpretation of the equal area rule

Marcos Rubinstein, Abraham Rubinstein

This paper presents a derivation and a physical interpretation of the equal area rule (EAR) for wire-grid simulation of surfaces. We propose a new procedure that leads to a formulation for obtaining the radii for an arbitrarily meshed surface. A simple com ...

The Concepts of IEC 61346 Applied to a Software Architecture for Automation

Esther Gelle

The IEC 61346 standard establishes general principles for structuring the information of technical systems. The present document discusses the ideas shown in the standard, emphasizing the fact that some parts of it are ambiguous and can lead to different i ...

Nonlocal plasticity models for localized failure

Simon Rolshoven

In quasi-brittle materials such as concrete, failure is preceded by highly localized deformation patterns. Localized failure is caused by strain softening, which cannot be described by classical local models, because they lack a length scale. Mathematicall ...

Numerical study of transitions in Taylor-Couette flow

This thesis is divided into two parts. In the first one the creation of a complete numerical tool, from the mesh generation to the data treatment, is presented. However time consuming this part has been, this is not the most important one. The second and m ...

Aspects of D-brane dynamics on orbifolds

Claudio Scrucca

We discuss D-brane dynamics in orbifold compactifications of type II superstring theory. We compute the interaction potential between two D-branes moving with constant velocities and give a field theory interpretation of it in the large distance limit. ...

Steady-State Solidification Of Reinforced Binary-Alloys

Andreas Mortensen

This paper provides a review of theoretical and experimental research to date on the constrained steady state solidification of dilute binary alloy matrix composites. Steady state solidification can be experimentally observed in composites which contain a ...

An alternative interpretation of the spectroscopy and internal dynamics of excited Cl2 molecules trapped in an argon matrix

Majed Chergui

Recent work on the spectroscopic and photophys. properties of the excited states of Cl2 trapped in an Ar matrix is compared with independent gas-phase results on Cl2 + rare gas as well as with other matrix studies. An alternative interpretation of the resu ...

Equilibre mécanique et de forme de petits cristaux

The gibbsian model for surfaces is reformulated in order to account for stress and strain within quasi-ideal crystals and on their surface. Tensor calculus, extensively used, leads to an invariant formalism. The symbols appearing therein are given a physic ...
