A flow sensing model for mesenchymal stromal cells using morphogen dynamics

Dominique Pioletti, Alexandre Terrier, Miguel Gortchacow

The differentiation of mesenchymal stromal cells has been shown to be af- fected by many parameters such as morphogens, flow rate, medium viscosity, and shear stress when exposed to fluid flow. The mechanism by which these cells sense their environment is ...

Numerical approximation of the unsteady Navier-Stokes equations with an application to the flow past a square cylinder

Francesco Casalegno

The goal of this project is to numerically solve the Navier-Stokes equations by using different numerical methods with particular emphasis on solving the problem of the flow past a square cylinder. In particular, we use the finite element method based on P ...

Experimental investigation on the aerodynamic loads and wake flow features of a low aspect-ratio circular cylinder

Giacomo Valerio Iungo

An experimental investigation on the flow features of the wake generated from a circular cylinder with finite height and placed vertically on a plane is presented. Through force measurements the mean drag coefficient is found to be roughly invariant by var ...

Discussion “Experimental study of velocity fields in rectangular shallow reservoirs”, Reply by the authors

Anton Schleiss, Erica Camnasio

The authors present the results of a new experimental study to improve the flow classification in rectangular shallow reservoirs. Although previous papers have paved the way for the classification (Dewals et al. 2008, Dufresne et al. 2010), the authors are ...

IMPROVING ACOUSTIC BASED KEYWORD SPOTTING USING LVCSR LATTICES

Petr Motlicek, Fabio Valente

This paper investigates detection of English keywords in a conversational scenario using a combination of acoustic and LVCSR based keyword spotting systems. Acoustic KWS systems search predefined words in parameterized spoken data. Corresponding confidence ...

Internal dynamics of Newtonian and viscoplastic fluid avalanches down a sloping bed

Christophe Ancey, Nicolas Andreini, Gaël Epely Chauvin

We experimentally investigated the spreading of fluid avalanches (i.e., fixed volumes of fluid) down an inclined flume. Emphasis was given to the velocity field within the head. Using specific imaging techniques, we were able to measure velocity profiles w ...

How oblique trailing edge of a hydrofoil reduces the vortex-induced vibration

François Avellan, Mohamed Farhat, Philippe Ausoni, Amirreza Zobeiri

The effect of hydrofoil trailing edge shape on the wake dynamic and flow induced vibration is investigated at high Reynolds number, Re = 0.5 x 10(6)-2.9 x 10(6). Two NACA 0009 hydrofoils with blunt and oblique trailing edges are tested. The velocity field ...

Patient specific numerical shoulder model based on medical imaging

Christoph Anselm Engelhardt

The shoulder is often described as the most complex human joint because of its anatomy and the high number of muscles participating in arm movements. The anatomy and the development of muscles depend on personal characteristics and the style of living. The ...

Modeling of Unsteady Friction and Viscoelastic Damping in Piping Systems

François Avellan, Christophe Nicolet, Christian Landry, Andres Müller

In real systems, the phenomena, such as pipe-wall viscoelasticity, unsteady friction or fluid structure interaction induce additional damping and dispersion of transient pressure waves than that defined by classical waterhammer. In this paper, unsteady fri ...
