High energy-density electrostatic actuators for soft robotics
This thesis reports high energy-density electrostatic actuators for use in soft robotics. This thesis has two main parts: a) a detailed study of electro-adhesion using microfabricated electrodes, and b) a flexi-ble fiber-shaped linear motor.Electro-adhesio ...
EPFL2024Re-design of EU DEMO with a low aspect ratio
The design point that had been chosen for EU DEMO in 2016 is reviewed here and a modification is proposed with a lower aspect ratio. Previously the same aspect ratio, A, was chosen for EU DEMO as in major tokamak experiments including ITER (A = 3.1), and, ...
2024A Review of Modeling, Design and Performance Assessment of Linear Electromagnetic Motors for High-Speed Transportation Systems
Mario Paolone, André Hodder, Lucien André Félicien Pierrejean, Simone Rametti
Linear electromagnetic motors (LEMs) have been proposed, developed and used to propel high-speed (i.e. speed > 100 m/s) levitating vehicles. However, few real implementations have demonstrated the feasibility of these machines at such speeds. Furthermore, ...
2024Modeling friction and wear using an adaptive discrete-continuum coupling
Manon Eugénie Voisin--Leprince
When two objects slide against each other, wear and friction occur at their interface. The accumulation of wear forms what is commonly referred to as a ``third-body''. Understanding third-body evolution has significant applications in industry, where contr ...
EPFL2024Performance Comparison of Cables With Partial Transposition
Pierluigi Bruzzone, Kamil Sedlák, Federica Demattè, Chiara Frittitta
The need of full transposition of the current carrying elements (strands) in large cables is frequently retained as top design criterion for conductors operating in pulsed mode. However, when the transposition error, i.e., the inductance difference among t ...
Piscataway2024Advanced control strategies to exploit the hydropower potential enhancing ancillary services provision to the power system
The European Union's Green Deal aims for a 55% reduction in greenhouse gas emissions by 2030. To reach this goal, a massive integration of Renewable Energy Sources (RES) into the power grid is necessary. As RES become a large part of the electricity genera ...
EPFL2024An aircraft assembly process formalism and verification method based on semantic modeling and MBSE
The aircraft assembly system is highly complex involving different stakeholders from multiple domains. The design of such a system requires comprehensive consideration of various industrial scenarios aiming to optimize key performance indicators. Tradition ...
Elsevier Sci Ltd2024Global fluid simulations of plasma turbulence in stellarators
António João Caeiro Heitor Coelho
In order to cope with the decarbonization challenge faced by many countries, fusion is one of the few alternatives to fossil fuels for the production of electricity. Two devices invented in the middle of the previous century have emerged as the most promis ...
EPFL2024'Fraternal-twin' ferroelectricity: competing polar states in hydrogen-doped samarium nickelate from first principles
In ferroelectric switching, an applied electric field switches the system between two polar symmetry-equivalent states. In this work, we use first-principles calculations to explore the polar states of hydrogen-doped samarium nickelate (SNO) at a concentra ...
Iop Publishing Ltd2024Alignment of ND3 molecules in dc-electric fields
Andreas Osterwalder, Viet Le Duc, Junwen Zou
The control of movement and orientation of gas-phase molecules has become the focus of many research areas in molecular physics. Here, ND3 molecules are polarized in a segmented, curved electrostatic guide and adiabatically aligned inside a rotatable mass ...
