Analysis of Pitot tube Airflow Velocity Sensor Behavior in Blockage Situations

Several airplanes crashes throughout the past decades are linked to the failure of the airplane flow velocity sensor known as pitot device or pitot tube. The study of its behavior in blockage, either due to human errors or due to environmental factors, cou ...

Time-Continuous Phosphorus Flows in the Indian Agri-Food Sector: Long-Term Drivers and Management Options

Claudia Rebeca Binder Signer

Phosphorus (P) is a major agricultural nutrient and, in its mineable form, a potentially scarce resource. Countries with limited physical access to P should hence develop an effective national P governance. This requires analyses of trends and variations i ...

Decoding the Grasping Intention from Electromyography during Reaching Motions

Aude Billard, Iason Batzianoulis, Nili Eliana Krausz

Background: Active upper-limb prostheses are used to restore important hand functionalities, such as grasping. In conventional approaches, a pattern recognition system is trained over a number of static grasping gestures. However, training a classifier in ...

Error performances of a model-based biplane fluoroscopic system for tracking knee prosthesis during treadmill gait task

Kamiar Aminian, Arnaud Barré

Roentgen stereophotogrammetry analysis technique allows an accurate measurement of knee joint prosthesis position and orientation using two X-ray images. Although this technique is used generally during static procedure, it is possible to use it with a bip ...

An Improved CFD Tool to Simulate Adiabatic and Diabatic Two-Phase Flows

Bogdan Alexandru Nichita

With increasing computer capabilities, numerical modeling of two-phase flows has developed significantly over the last few years. Although there are two main categories, namely 'one' fluid and 'two' fluid methods, the 'one' fluid methods are more commonly ...

A 10-gram Vision-based Flying Robot

Dario Floreano, Jean-Daniel Nicoud, Jean-Christophe Zufferey, Antoine Beyeler, Adam Klaptocz

We aim at developing ultralight autonomous microflyers capable of freely flying within houses or small built environments while avoiding collisions. Our latest prototype is a fixed-wing aircraft weighing a mere 10 g, flying around 1.5 m/s and carrying the ...

Hydrodynamics of the free surface flow in Pelton turbine buckets

Alexandre Perrig

The design of Pelton turbines has always been more difficult than that of reaction turbines, and their performances lower. Indeed, the Pelton turbines combine 4 types of flows: (i) confined, steady-state flow in the piping systems and injector, (ii) free w ...
