PMU-Embedded Analytics for Online Event Detection and Classification in Power Grids
The energy requirement of the world is increasing exponentially every year. With the power demand sites concentrated in the region with the highest population density, energy production sites must be located remotely. This isolation requires lengthy and complicated grids to be designed and manufactured to transmit power over long distances. Grid failures...

Hydrothermal Crystal Growth that Eliminates Spontaneous Emission
This hydrothermal approach to growing single crystal oxide hosts resolves the issues posed by amplified spontaneous emission (ASE). ASE is the result of unwanted internal reflection of photons at the lasing frequency within the laser crystal. The consequences of ASE include induced emission of ions from the excited state and unwanted internal lasing...
