Shear resistance of lightweight concrete core of FRP-concrete sandwich structure

Thomas Keller, Till Vallée, Erika Schaumann

This paper presents a model to predict the shear resistance of the unreinforced lightweight concrete core of a recently developed hybrid sandwich concept for bridge decks. The sandwich skins consist of a fiber-reinforced polymer (FRP) composite sheet for t ...

Quantification of the body sway using 3D inertial sensors

Jonathan Bernard

Balance impairment is one of the major contributors to fall, frequently amenable to surgical intervention. Repeated falls can lead to bad injuries which can decrease or even stop the professional and social activities. The study of the static equilibrium i ...

Decay mechanisms of excited electrons in quantum-well states of ultrathin Pb islands grown on Si(111): Scanning tunneling spectroscopy and theory

Wolf-Dieter Schneider, François Patthey, I-Po Hong

Using low-temperature scanning tunneling spectroscopy at 5 and 50 K, we studied the linewidth of unoccupied quantum-well states in ultrathin Pb islands, grown on Si(111) on two different Pb/Si interfaces. A quantitative analysis of the differential conduct ...

Determination of the viscosity of the ionic liquids [bmim][PF6] and [bmim][TF2N] under high CO2 gas pressure using sapphire NMR tubes

Paul Joseph Dyson, Gabor Laurenczy

The viscosities of the ionic liqs. [bmim][PF6] and [bmim][TF2N] (bmim = 1-methyl-3-butylimidazolium, TF2N = bis(trifluoromethylsulfonyl)imide) have been detd. under CO2 pressure at 298 K. The viscosity decreases from 381 to 23 cP for [bmim][PF6] without CO ...

Scaling of capillary, gravity and viscous forces affecting flow morphology in unsaturated porous media

Dani Or

Interplay between capillary, gravity and viscous forces in unsaturated porous media gives rise to a range of complex flow phenomena affecting morphology, stability and dynamics of wetting and drainage fronts. Similar average phase contents may result in si ...

Simulating Viscoplastic Avalanches.

Christophe Ancey, Martin Rentschler

We present a comparison between experiment and numerical results for the dam-break problem involving viscoplastic fluids. The laboratory experiment consists in releasing a fine volume of a viscoplastic fluid down inclined plane and tracking the evolution o ...

Nanomechanical properties of biopolymers

Camilo Guzman

This thesis presents, develops and applies new methodologies that can quantitatively probe the mechanical and viscoelastic properties of biomaterials at the nanoscale. Elastic and viscous properties are important characteristics of materials, such as many ...

Subfilter-scale fluxes over a surface roughness transition. Part II: Evaluation of large-eddy simulation models

Fernando Porté Agel

The ability of subfilter-scale (SFS) models to reproduce the statistical properties of SFS stresses and energy transfers over heterogeneous surface roughness is key to improving the accuracy of large-eddy simulations of the atmospheric boundary layer. In t ...

Subfilter-scale fluxes over a surface roughness transition. Part I: Measured fluxes and energy transfer rates

Fernando Porté Agel

A wind-tunnel experiment was designed and carried out to study the effect of a surface roughness transition on subfilter-scale (SFS) physics in a turbulent boundary layer. Specifically, subfilter-scale stresses are evaluated that require parameterizations ...
