A traveling wave decelerator for neutral polar molecules

Andreas Osterwalder

Recently, a decelerator for neutral polar molecules has been presented that operates on the basis of macroscopic, three-dimensional, traveling electrostatic traps [A. Osterwalder, S. A. Meek, G. Hammer, H. Haak, and G. Meijer, Phys. Rev. A 81, 051401 (2010 ...

Modelization of a self-opening peripheral neural interface: A feasibility study

Silvestro Micera

In this paper a self-opening intrafascicular neural interface (SELINE) has been modeled using both a theoretical approach and a Finite Element (FE) analysis. This innovative self opening interface has several potential advantages such as: higher selectivit ...

Numerical analysis of the Navier-Stokes/Darcy coupling

Alfio Quarteroni, Marco Discacciati

We consider a differential system based on the coupling of the Navier-Stokes and Darcy equations for modeling the interaction between surface and porous media flows. We formulate the problem as an interface equation, we analyze the associated (nonlinear) S ...

A self-learning algorithm for biased molecular dynamics

Michele Ceriotti, Gareth Aneurin Tribello, Michele Parrinello

A new self-learning algorithm for accelerated dynamics, reconnaissance metadynamics, is proposed that is able to work with a very large number of collective coordinates. Acceleration of the dynamics is achieved by constructing a bias potential in terms of ...

Buckled Bridges Using Film Stress for Three-Dimensional Structures: Effects of Lateral Designs on Vertical Profiles and Dynamic Characteristics

Nico de Rooij, Danick Briand

Bridges buckled by film stress call generate a vertical displacement resulting in three-dimensional structures. We have demonstrated a micromirror lifted by buckled bridges and a vertical comb drive actuator. The structures show rounded profiles in a stabl ...

AdS/QCD: the relevance of the geometry

Andrea Wulzer, Michele Redi, Diego Becciolini

We investigate the relevance of the metric and of the geometry in five-dimensional models of hadrons. Generically, the metric does not affect strongly the results and even flat space agrees reasonably well with the data. Nevertheless, we observe a preferen ...

Simulation numérique de phénomènes MHD

Gilles Steiner

The purpose of this thesis is the study, from the numerical simulation point of view, of the aluminum electrolysis process. Navier-Stokes equations for the computation of a two fluids flow with free interface are coupled with Maxwell equations describing t ...

Numerical Models for Differential Problems

Alfio Quarteroni

In this text, we introduce the basic concepts for the numerical modelling of partial differential equations. We consider the classical elliptic, parabolic and hyperbolic linear equations, but also the diffusion, transport, and Navier-Stokes equations, as w ...

A 1D Model For A Closed Rigid Filament In Stokes Flow

Philippe Caussignac

We adapt an existing asymptotic method to set up a one-dimensional model for the fall of a closed filament in an in finite fluid in the Stokes regime. Starting from the single-layer integral representation of the fluid velocity around the filament, we get, ...

Dynamics and Control of 2D SpiderCrane: A Lie-Bäcklund Approach

Dominique Bonvin, Philippe Müllhaupt

In this paper we present modeling and control of a multicable suspended mechanism called the ‘2D SpiderCrane’. The use of cables, and thus avoiding conventional heavy components, makes such a mechanism suitable for working at high transfer speeds. The init ...
