Identification of recloser and fuse operations is an important task in a distribution system to help evaluate overcurrent coordination, detect incorrect relay settings, and estimate fault location. The main purpose of this paper is to develop rule-ba

Capacitor banks are commonly connected to the power system to enhance its reliability by providing voltage support, improving power factor, and increasing the system capacity. They are usually switched in and out of the system according to the amount

Previously, we have reported on high-density photon-gated spectral hole burning in europium-doped alkaline earth sulfides. Enhanced inhomogeneous broadening of the zero phonon line (ZPL) has been achieved by embedding MgS : Eu 2+ and CaS : Eu 2+ in P

We present the case of photoionization-induced holeburning in rare-earth-doped II–VI compounds for high-density persistent holeburning. In this case, the photoproduct of holeburning is distributed across the entire zero-phonon line. This maximizes

In this paper we report optical hole-burning in nano- particles of MgS doped with Eu. Nano-particles have been produced by quench condensing the laser-ablated vapors from a solid target. Particle size has been controlled by the pressure of the ambien

In the form of micro-particles europium doped alkaline earth sulfides have been shown to exhibit high density of permanent spectral holes. The photon-gated spectral holeburning (PGHB) in these systems provided the most promising characteristics of an

For frequency domain storage rare earth doped sulfide show the most promising characteristics of any spectral holeburning material known. They provide the desired density of storage with a remarkable stability of memory against storage, read- out, an

We present the case of photoionization-induced persistent spectral holeburning in rare earth doped II-VI compounds for high density memory storage. Experimental data on photon-gated holeburning has been presented for different sulfide hosts (MgS, CaS

The mechanism for highly efficient photoionization spectral hole burning in the 4f7–4f65d1 transition of Eu2+ in MgS host is investigated in detail. The time and power dependencies of the hole depth and its photoerasure are analyzed assuming that a
