Context-Aware Monitoring of Hand Motor Primitives in Daily Life Activities: A Pathway to Objectively Assess Rehabilitation of Patients with Upper-Limb Neurological Impairment
The hands, our silent performers in daily life, face overwhelming challenges when neurological impairments disrupt the simple tasks that compose our daily symphony. This thesis unveils a comprehensive framework for the objective monitoring of upper-limb re ...
EPFL2024Damping of flexure blades based on bi-material additive manufacturing
Simon Nessim Henein, Florent Cosandier, Nicolas Blondiaux, Loïc Benoît Tissot-Daguette, Elias Sebastian Klauser, Florent Alexandre Boudoire, Nikola Kalentics, Lisa Salamin
Flexure-based mechanisms have become state-of-the-art solutions for the design of high-precision mechanisms, free from friction wear, backlash, and lubrication. These properties which are necessary for applications in ultraclean or harsh environments, neve ...
2023Experimental investigation of surface roughness effect on a free-flight sphere in a Ludwieg tube
Understanding the aerodynamic coefficients of meteoroid fragments, deorbiting space debris, or launch vehicle stages through atmospheric reentry is essential for ground risk assessments. In high enthalpy flow, surface roughness is a crucial factor affectin ...
KOREAN SOC MECHANICAL ENGINEERS2022Mechanical design of the optical unit and structural subsystem for a lunar camera
The project was initiated by the Moon Village Association (MVA). It is a non-governmental association which regulates the exploration program of lunar missions. The MVA also works on the development of space technologies: the Payload1 project is a part of ...
2022Euclid: Searching for pair-instability supernovae with the Deep Survey
Frédéric Courbin, Georges Meylan, Giovanni Longo, Yi Wang, Richard Massey
Pair-instability supernovae are theorized supernovae that have not yet been observationally confirmed. They are predicted to exist in low-metallicity environments. Because overall metallicity becomes lower at higher redshifts, deep near-infrared transient ...
EDP SCIENCES S A2022Nondestructive Prediction of the Buckling Load of Imperfect Shells
Tobias Schneider, Emmanuel Georges Albert Virot, Emilio José Lozano Vazquez
From soda cans to space rockets, thin-walled cylindrical shells are abundant, offering exceptional load carrying capacity at relatively low weight. However, the actual load at which any shell buckles and collapses is very sensitive to imperceptible defects ...
AMER PHYSICAL SOC2020High-Power Testing of Guided-Wave Components for the ITER ECH Upper Launcher at the FALCON Test Facility
Timothy Goodman, René Chavan, Matteo Vagnoni
Each of the four ITER electron cyclotron heating (ECH) upper launchers (ULs) features eight transmission lines (TLs) made of guided-wave components used to inject 170-GHz microwave power into the plasma at a level of up to 1.31 MW per line, at the TL diamo ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2020Structural pre-conceptual design studies for an EU DEMO equatorial EC port plug and its port integration
For the EU DEMO Tokamak, Electron Cyclotron (EC) launching systems for plasma heating and stabilization are under development. Various concepts for the optical system are currently studied of which the Mid Steering Antenna (MSA) with a steering mirror at a ...
Elsevier2020Antennas for CubeSat Communication
CubeSats are a type of small satellites (< 500 kg) that weigh several kilograms and consist of multiple Units (U) measuring 100 × 100 × 113.5 mm3. CubeSats emerged as a low-cost alternative to conventional large satellites, and have since demonstrated capa ...
EPFL2020Nearing final design of the ITER EC H&CD Upper Launcher
Olivier Sauter, Timothy Goodman, René Chavan, Jean-Daniel Landis, Robert Bertizzolo, Matteo Vagnoni, Florian Ramseyer, Emanuele Poli
The ITER ECRH system consists of 24 gyrotrons with up to 24 MW installed millimeter wave heating power at 170 GHz, power supplies, control system, transmission lines, one Equatorial and the four Upper Launchers. With its high frequency and small beam focus ...
