Probabilistic Learning of Torque Controllers from Kinematic and Force Constraints

Sylvain Calinon

When learning skills from demonstrations, one is often required to think in advance about the appropriate task representation (usually in either operational or configuration spaces). We here propose a probabilistic approach for simultaneously learning and ...

Characterization and Compact Modeling of Nanometer CMOS Transistors at Deep-Cryogenic Temperatures

Edoardo Charbon, Harald Arjan Robert Homulle, Fabio Sebastiano

Cryogenic characterization and modeling of two nanometer bulk CMOS technologies (0.16-μm and 40-nm) are presented in this paper. Several devices from both technologies were extensively characterized at temperatures of 4 K and below. Based on a detailed und ...

High Power Electronics Innovation Perspectives for Pumped Storage Power Plants

Drazen Dujic, Pedro Camilo de Oliveira e Silva, Miodrag Basic

The current framework of high penetration of intermittent energy sources requires variable-speed pumped hydro storage power plants (PHSPs) to provide grid support functions, which are, in this case, achieved through two technologies: doubly-fed induction m ...

Imaging neural activity in the ventral nerve cord of behaving adult Drosophila

Michaël Unser, Pavan P Ramdya, Florian Aymanns, Denis Fortun, Chin-Lin Chen, Laura Joan Hermans

To understand neural circuits that control limbs, one must measure their activity during behavior. Until now this goal has been challenging, because limb premotor and motor circuits have been largely inaccessible for large-scale recordings in intact, movin ...

Allocation of Frequency Control Reserve from Aggregated Resources of Active Distribution Systems

Fabrizio Sossan, Mokhtar Bozorg, Mohsen Kalantar Neyestanaki

This paper addresses the allocation of frequency control services (FCSs) from aggregated resources of active distribution systems (ARADSs) for balancing the transmission system while considering credible contingencies as well as forecast error of loads and ...

Rotating air-water ring in the vaneless gap of a pump-turbine operating in condenser mode

François Avellan, Elena Vagnoni, Loïc Andolfatto, Pierre Leroy

The rotating air-water ring, featuring a bubbly flow, in the vaneless gap of a reduced scale physical model of a pump-turbine operating in dewatered condition is investigated. High speed visualizations are performed together with pressure fluctuation measu ...
