Phase Dependency of the Human Primary Motor Cortex and Cholinergic Inhibition Cancelation during Beta tACS [PDF]

open access: yes, 2016
The human motor cortex has a tendency to resonant activity at about 20 Hz so stimulation should more readily entrain neuronal populations at this frequency.

Comparative performance study of alternate fault-tolerant inverter configurations for direct torque control-based three-phase PM BLAC drives under single-phase open-circuit fault [PDF]

open access: yes, 2016
This paper presents a comparative performance study of three typical fault-tolerant control (FTC) topologies [split-capacitor (SC), extra-leg split-capacitor (ELSC), and extra-leg extraswitch (ELES)] for direct torque control (DTC)-based threephase ...

High Impedance Single-Phase Faults Diagnosis in Transmission Lines via Deep Reinforcement Learning of Transfer Functions

open access: yesIEEE Access, 2021
Accurate and fast fault detection in transmission lines is of high importance to maintain the reliability of power systems. Most of the existing methods suffer from false detection of high-impedance faults.
