An experimental validation of partial discharge localization using electromagnetic time reversal

Marcos Rubinstein, Mohammad Azadifar, Hamidreza Karami

The localization of partial discharge (PD) sources is of importance for the monitoring and maintenance of power transformers. Time difference of arrival (TDoA) based methods are widely adopted in the literature for the localization of PDs. Recently, time r ...

Design and dynamic analysis of soft pneumatic systems for wearable robots

Sagar Dattatray Joshi

There are many challenges in the development of pneumatically powered soft robots due to the non-linearities of the materials used, non-linear pneumatic flow, complex non-standard designs, and high compliance that leads to loading-specific mechanical behav ...

Novel Optimized Shape and Topology for Slotless Windings in BLDC Machines

Yves Perriard, Douglas Martins Araujo, Adrien Jean-Michel Thabuis, Guillaume Paul-André Burnand

Slotless windings are commonly used in small size high-speed electrical brushless dc machines. Unlike slotted windings, forced to follow the direction of slots, slotless windings can be freely arranged in the airgap. This represents several opportunities f ...

Design and development of the efficient anguilliform swimming robot- MAR

Auke Ijspeert, Peter Eckert, Anouk Looijestijn

Propulsion of swimming robots at the surface and underwater is largely dominated by rotary propellers due to high thrust, but at the cost of low efficiency. Due to their inherently high speed turning motion, sharp propeller blades and generated noise, they ...

Small scale very high speed slotless permanent magnet motors

Guillaume Paul-André Burnand

This research work has been triggered by an industrial project aimed at modelling and manufacturing a small-scale very high speed motor. Very high speed electrical motors offer the main advantage of reducing the size of a system. Indeed, at constant output ...

Partial Discharge Localization Using Time Reversal: Application to Power Transformers

Marcos Rubinstein, Mohammad Azadifar, Amirhossein Mostajabi, Hamidreza Karami

In this work, we present a novel technique to locate partial discharge (PD) sources based on the concept of time reversal. The localization of the PD sources is of interest for numerous applications, including the monitoring of power transformers, Gas Insu ...

Motor improvement estimation and task adaptation for personalized robot-aided therapy: a feasibility study

Silvestro Micera, Elvira Pirondini, Jenifer Cléa Miehlbradt, Nawal Noëlle Kinany, Martina Coscia, Christian Giang, Camilla Pierella

Background In the past years, robotic systems have become increasingly popular in upper limb rehabilitation. Nevertheless, clinical studies have so far not been able to confirm superior efficacy of robotic therapy over conventional methods. The personaliza ...

Protection Coordination in Marine DC Power Distribution Networks

Seongil Kim

The increasing penetration of renewable energy sources, energy storage systems (ESSs), and DC loads has opened the door to DC technology to pave its way into future grids. The shift has been more obvious in the marine domain supported by track records of i ...

Amplified engagement of prefrontal cortex during control of voluntary action in Tourette syndrome

Sophie Jacqueline Andrée Betka

Tourette syndrome is characterized by 'unvoluntary' tics, which are compulsive, yet often temporarily suppressible. The inferior frontal gyms is implicated in motor control, including inhibition of pre-potent actions through influences on downstream subcor ...
