Shoulder Apprehension Impacts Large-Scale Functional Brain Networks

BACKROUND AND PURPOSE: Shoulder apprehension is defined as anxiety and resistance in patients with a history of anterior glenohumeral instability. It remains unclear whether shoulder apprehension is the result of true recurrent instability or a memorized s ...

Advanced Automotive System based on Modular Multilevel Converter

Rosa Martel Danoary Tsirinomeny

Battery packs in recent electric vehicles (EVs) have high energy and high power densities which exerts a strong thermal stress upon them. This means that the individual battery cells are more prone to decline away and eventually fail early because of an ex ...

Power Compensation Approach and Double Frame Control for Grid Connected Converters

Alfred Rufer, Daniel Siemaszko

The handling of weak networks with asymmetric disturbances implies the accurate handling of the second harmonic component appearing under unbalanced networks. This paper proposes a two-step approach using classic vector control for operating the current co ...

Brain-Controlled Wheelchairs: A Robotic Architecture

José del Rocio Millán Ruiz, Tom Edward Carlson

Independent mobility is core to being able to perform activities of daily living by oneself. However, powered wheelchairs are not an option for a large number of people who are unable to use conventional interfaces, due to severe motor–disabilities. Non-in ...

Dynamical Movement Primitives: Learning Attractor Models for Motor Behaviors

Auke Ijspeert

Nonlinear dynamical systems have been used in many disciplines to model complex behaviors, including biological motor control, robotics, perception, economics, traffic prediction, and neuroscience. While often the unexpected emergent behavior of nonlinear ...

First pulse technique for brushless DC motor standstill position detection based on iron B-H hysteresis

Yves Perriard, Miroslav Markovic, Omar Scaglione

This paper introduces a promising technique, called the first-pulse technique, for detecting the rotor position of a brushless DC motor at standstill. The technique is based on the B-H hysteresis characteristics of the stator iron. Depending on the rotor p ...

Transient Recovery Voltages in Vacuum Circuit Breakers Generated by the Interruption of Inrush Currents of Large Motors

Mario Paolone, Carlo Alberto Nucci

The switching of medium voltage electrical motors is typically realized by means of vacuum circuit breakers (VCBs) essentially in view of their elevated number of switching cycles. As known, switching of VCBs generates important transient recovery voltages ...

Impact of Inhomogeneities in HTS Coated Conductors for Resistive FCLs

Frédéric Sirois, Daniele Colangelo, Bertrand Dutoit

Several issues remain to be addressed for the commercial development of ResistiveFault Current Limiters based on superconducting technologies (RFCL). In particular, the inhomogeneity of high temperature superconducting coated conductors (HTS-CC) combined w ...

An Analytical Solution for the Torque and Power of a Solid-Rotor Induction Motor

Yves Perriard, Miroslav Markovic

An analytical solution for the torque and power of a solid-rotor two-pole three-phase slotless induction motor is presented. The field excitation is a current layer placed at the stator interior surface. The solution is based on an analytical solution of t ...

Current ripple in inverter-fed five-phase drives with space-vector PWM

Drazen Dujic

A number of PWM techniques have been developed in recent times for five-phase voltage source inverters (VSIs), which enable sinusoidal output voltage generation. Relatively little attention has been however paid to the current ripple caused by these PWM me ...
