Prediction and Comparison of low-Reynolds Airfoil Performance

Vincent François-Charles Rolin, Eric Sauvageat

This semester project is aiming to compare different airfoils in order to select the most promising one as blade shape for scaled the straight-bladed giromills used in wind tunnel experiments. For this matter, a large amount of steady-state CFD-simulations ...

Influence of boundary conditions on the out-of-plane response of brick masonry walls in buildings with RC slabs

Katrin Beyer, Marco Tondelli

In modern unreinforced masonry buildings with stiff RC slabs, walls of the top ﬂoor are most susceptible to out-of-plane failure. The out-of-plane response depends not only on the acceleration demand and wall geom-etry but also on the static and kinematic ...

Force-based higher-order beam element with flexural-shear-torsional interaction in 3D frames. Part II: Applications

João Saraiva Esteves Pacheco de Almeida

The specific features of the proposed force-based formulation derived in the companion paper, which is applied for the first time to higher-order beam theories, are herein thoroughly validated. Introductory numerical examples illustrate the influence of me ...

Parallel imaging with phase scrambling

Rolf Gruetter, Daniel Gallichan

PURPOSE: Most existing methods for accelerated parallel imaging in MRI require additional data, which are used to derive information about the sensitivity profile of each radiofrequency (RF) channel. In this work, a method is presented to avoid the acquisi ...

Mind The Gap

Matthieu Dreyer

The tip leakage vortex (TLV), which develops in the clearance between the blade tip and the casing of axial turbomachines, appears in many industrial applications, such as air transportation, space rockets and hydraulic machines. In the latter, cavitation ...

Optimisation of industrial production of low-force sensors – adhesive bonding of force-centring ball

Peter Ryser, Thomas Maeder, Caroline Jacq, Maxime Blot

This work addresses the issue of attaching the force-centring part (a round ball) to the load cell of a force sensor, a piezoresistive thick-film Wheatstone bridge deposited onto a ceramic cantilever. As the current soldering process requires expensive met ...

Maximizing the displacement of compact planar dielectric elastomer actuators

Herbert Shea, Samuel Rosset

We present a model and its experimental validation for the optimization of the in-plane displacement of a rigid platform mounted on a compact dielectric elastomer actuator. Unlike the situation in which the mechanical prestretch of the membrane is maintain ...

Carbon Nanotubes

Jaap Kroes

This thesis studies carbon nanotubes using state-of-the-art computational methods. Using large-scale quantum-mechanical calculations, based on density-functional-theory, we investigate several important aspects of the physics and chemistry of single-walled ...

Characterizing and Understanding Divalent Adsorbates on Carbon Nanotubes with Ab Initio and Classical Approaches: Size, Chirality, and Coverage Effects

Wanda Andreoni, Fabio Pietrucci, Alessandro Curioni

The study of oxygen chemisorption on single-walled carbon nanotubes generally relies on simple atomistic models and hence hampers the possibility to understand whether nanotube size or adduct concentration have a role in determining the surface adsorbate i ...

Breaking Size-Segregation Waves in Granular Avalanches

Christophe Ancey, Kasper van der Vaart

We experimentally prove the existence of the theoretically predicted breaking size-segregation wave within a binary granular avalanche. This complex structure involves the recirculation of particles through a pattern of shocks and rarefaction waves, and ca ...
