The On-Line Electric Vehicle (OLEV) is an innovative electricity-powered transportation system which remotely picks up electricity from power transmitters buried underground. Selected as one of “the 50 Best Innovations of 2010” by TIME Magazine, the OLEV is considered as a potential solution for the next generation electric-powered public bus system in Seoul. The prototype of the OLEV based bus...

This paper proposes a mathematical model of electric and magnetic fields caused by high voltage conductors of electric power transmission systems by using a set of second-order partial differential equations. This study has considered the effect of conductor phase-sequence orientation on electromagnetic fields emitted around a double-circuit, extra high-voltage, power transmission line. Five ty...

In this paper principles of extended Kalman filtering theory is developed and applied to simulated on-line electric power systems state estimation in order to trace the operating condition changes through the redundant and noisy measurements. Test results on IEEE 14 - bus test system are included. Three case systems are tried; through the comparing of their results, it is concluded that the pro...

This study aims at investigation of stimulation by using intra-spinal signals decoded from electrocorticography (ECoG) assessments to restore the movements of the leg in an animal model of spinal cord injury (SCI). The present work comprised of three steps. First, ECoG signals and the associated leg joint changes (hip, knee, and ankle) in sedated healthy rabbits were recorded in different trial...

This research is concerned with the anti-plane strain problems of polarized ceramics with both the couple stress and electric field gradient effects. This theory possesses two characteristic lengths l1 and l2 which are determined explicitly. In addition the two characteristic lengths can be either positive real or complex conjugate with positive real part. We first investigate the electroelasti...

this paper proposes a new method for transmission loss allocation. the share of each bus in the transmission line losses is determined using transmission line loss equations with respect to bus-injected currents. then, it is applied to the total network transmission lines. in the proposed method, comparing with other methods, a solution to remove the negative loss allocation has been introduced...

Atmospheric pressure plasma produced by a slot antenna with a pulsed microwave excitation was investigated to understand an electric field influence on hydrogen Balmer- (H) spectral profile using spaceand time-resolved optical emission spectroscopy. Paralleland perpendicular-polarized H emission line profiles with respect to the microwave electric field direction were measured by a polarizat...
