A randomised controlled clinical trial and gait analysis of fixed- and mobile-bearing total knee replacements with a five-year follow-up

Kamiar Aminian, Brigitte Jolles-Haeberli, Hooman Dejnabadi

This study compared the outcome of total knee replacement (TKR) in adult patients with fixed- and mobile-bearing prostheses during the first post-operative year and at five years' follow-up, using gait parameters as a new objective measure. This double-bli ...

Discrete vs continuum level simulation of radiative transfer in semitransparent two-phase media

Sophia Haussener

The mathematical formulation of the continuum approach to radiative transfer modeling in two-phase semi-transparent media is numerically validated by comparing radiative fluxes computed by (i) direct, discrete-scale and (ii) continuum-scale approaches. The ...

Implementing global Abelian symmetries in projected entangled-pair state algorithms

Due to the unfavorable scaling of tensor-network methods with the refinement parameter M, new approaches are necessary to improve the efficiency of numerical simulations based on such states, in particular for gapless, strongly entangled systems. In one-di ...

Cost-efficient and Differentiated Data Availability Guarantees in Data Clouds

Karl Aberer, Nicolas Bonvin

Failures of any type are common in current datacenters. As data scales up, its availability becomes more complex, while different availability levels per application or per data item may be required. In this paper, we propose a self- managed key-value stor ...

Predicting Usefulness of Measuring Structures during Load Tests

Ian Smith, James-Alexandre Goulet

This paper presents an approach for model identifiability that builds upon recent research into measurement data interpretation. The objective of this approach is to determine probabilistically to what degree the number of models able to explain a measured ...

Carbon outclasses wood in racket paddles: Ratings of expert and intermediate tennis players

Michael Herzog, Olaf Blanke, Véronique Michaud, Christian Fischer

Wooden racket paddles were modified with rubber and carbon fibre laminates and their differences tested in terms of flexural, damping, and coefficient of restitution properties. Four rackets types were designed: a wood reference, wood with rubber, carbon f ...

Knowledge interdependence with the partner, accuracy of mutual knowledge model and computer-supported collaborative learning

Pierre Dillenbourg, Mirweis Sangin, Gaëlle Molinari

The present study is part of a project aiming at empirically investigating the process of modeling the partner’s knowledge (Mutual Knowledge Modeling or MKM) in Computer-Supported Collaborative Learning (CSCL) settings. In this study, a macro-collaborative ...

A Full-Scale Particle Image Velocimetry Investigation of “Young” Rotor Blade Tip Vortices

Karen Ann J Mulleners, Kolja Kindler

The blade tip vortex of a full-scale MBB Bo 105 Helicopter is investigated experimentally under simulated hover flight conditions in ground effect by means of stereoscopic Particle Image Velocimetry. Based on the three-component velocity field of azimuthal ...

Quasi-static cyclic tests and plastic hinge analysis of RC structural walls

Katrin Beyer, Alessandro Dazio

This paper presents the results of quasi-static cyclic tests on six reinforced concrete (RC) walls performed at the ETH Zurich. These large-scale tests investigate the effect of different vertical reinforcement contents and different reinforcement ductilit ...

Dynamic models for the subgrid-scale mixing of reactants in atmospheric turbulent reacting flows

Fernando Porté Agel

The effects of the subgrid scales on chemical transformations in large-eddy simulations of the convective atmospheric boundary layer (CBL) are investigated. Dynamic similarity subgrid-scale models are formulated and used to calculate the subgrid-scale cova ...
