The right and left hand Motor Imagery (MI) analysis based on the electroencephalogram (EEG) signal can directly link the central nervous system to a computer or a device. This study aims to identify a set of robust and nonlinear effective brain connectivity features quantified by transfer entropy (TE) to characterize the relationship between brain regions from EEG signals and create a hierarchi...
in recent years, based on the growing importance of clean energy in comparison with conventional energy production from fossil fuels, dg systems are gradually becoming more popular all over the world. these resources solve many problem of system. however, these resources create some other problems too. one of the most problem of dgs is unwanted islanding. this paper addresses reliable passive i...
Sensory and motor noise limits the precision with which we can sense the world and act upon it. Recent research has begun to reveal computational principles by which the central nervous system reduces the sensory uncertainty and movement variability arising from this internal noise. Here we review the role of optimal estimation and sensory filtering in extracting the sensory information require...
Rotor slots in induction motor expand due to thermal imbalance and create magnetic stress. Magnetic stress is a force that develops on the laminated surface of rotor curving or stretching flux. Traditional fault detection methods never measure rotor; significant problem frequently arises motor. proportional slot size variations rotor. High lead more flux damage stator, reducing their efficiency...
The reversal of flagellar motion (switching) results from the interaction between a switch complex of the flagellar rotor and a torque-generating stationary unit, or stator (motor unit). To explain the steeply cooperative ligand-induced switching, present models propose allosteric interactions between subunits of the rotor, but do not address the possibility of a reaction that stimulates a bidi...
One of the important issues in designing a brain-computer interface system is to select the type of mental activity to be imagined. In some of these systems, mental activity varies with user intent and action that must be controlled by the brain-computer system, and in a number of other signals, the received signals contain the same activity-related mental activity that should be performed by t...
Induction motors are indispensable, robust, and reliable machines for industry; however, as with any machine, they susceptible to diverse faults. Among the faults that a motor can suffer, broken rotor bars (BRBs) have become one of most studied ones because under this fault condition continue operating apparent normality, yet severity quickly increase and, consequently, generate whole collapse ...
Background: Valproic acid (VPA) is used to be an effective anti-epileptic drug and mood stabilizer. It has recently been demonstrated that VPA could promote neurite outgrowth, activate the extracellular signal regulated kinase pathway, and increases bcl-2 and growth cone-associated protein 43 levels in spinal cord. In the present research we demonstrate the effect of VPA on peripheral nerve r...
