IGS: an IsoGeometric approach for Smoothing on surfaces

Pierre Wilhelm, Luca Dede', Matthieu Wilhelm

We propose a novel approach for smoothing on surfaces. More precisely, we aim at estimating functions lying on a surface, starting from noisy and discrete measurements. The surface is represented by NURBS, which are geometrical representations commonly use ...

Relevance of the Drag Force during Controlled Translocation of a DNA–Protein Complex through a Glass Nanocapillary

Aleksandra Radenovic, Sanjin Marion, Roman Bulushev

Combination of glass nanocapillaries with optical tweezers allowed us to detect DNA-protein complexes in physiological conditions. In this system, a protein bound to DNA is characterized by a simultaneous change of the force and ionic current signals from ...

Adjustment of Turbulent Boundary-Layer Flow to Idealized Urban Surfaces: A Large-Eddy Simulation Study

Fernando Porté Agel, Wai Chi Cheng

Large-eddy simulations (LES) are performed to simulate the atmospheric boundary-layer (ABL) flow through idealized urban canopies represented by uniform arrays of cubes in order to better understand atmospheric flow over rural-to-urban surface transitions. ...

Small scale variability of snow density on Antarctic sea ice

Michael Lehning, Katherine Colby Leonard, Nander Wever

Snow on sea ice plays an important role in air-ice-sea interactions, as snow accumulation may for example increase the albedo. Snow is also able to smooth the ice surface, while at the same time it may generate roughness elements by interactions with the w ...

Measurement of the dynamics in ski jumping using a wearable inertial sensor-based system

Kamiar Aminian, Julien Favre, Julien Chardonnens

Dynamics is a central aspect of ski jumping, particularly during take-off and stable flight. Currently, measurement systems able to measure ski jumping dynamics (e.g., 3D cameras, force plates) are complex and only available in few research centres worldwi ...

Sensitivity of aerodynamic forces in laminar and turbulent flow past a square cylinder

François Gallaire, Edouard Boujo, Philippe Meliga

We use adjoint-based gradients to analyze the sensitivity of the drag force on a square cylinder. At Re = 40, the flow settles down to a steady state. The quantity of interest in the adjoint formulation is the steady asymptotic value of drag reached after ...

Vertical take-off and landing aerial vehicle

Dario Floreano, Jean-Christophe Zufferey, Adrien Briod, Adam Klaptocz, Przemyslaw Mariusz Kornatowski, Ludovic Daler, Arnaud Garnier

A VTOL (vertical take-off and landing) aerial flying vehicle comprising an inner frame, a gimbal system and an outer frame, the inner frame comprising a propulsion system and a control system, the propulsion system being able to generate a lift force. The ...

A linearized approach for the control of aerodynamic forces in flow past a square cylinder

François Gallaire, Edouard Boujo, Philippe Meliga

The analysis of Strykowski & Sreenivasan (JFM, 1990) provides experimental evidence that a small control cylinder suitably positioned in the wake of a main cylinder can alter vortex shedding close to the instability threshold. This problem was addressed fr ...
