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...

Engineered Aquaculture Ecosystem for Managing Wastewater
This aquaculture ecosystem utilizes low RPM paddlewheels to control water flow rate and feed fish waste to algae to reduce eutrophication effects. For every ton of fish produced as much as 66 kilograms of nitrogen waste and 10.5 kilograms of phosphorus waste are produced. The waste feeds plankton and algae, and in excess can lead to blooms and then...

Distributed Feedback Fiber Laser Pumped by Multimode Diode Lasers
Researchers at the University of Arizona College of Optical Sciences and Canada's Carleton University recently succeeded in fabricating high reflectivity (>99%) Fiber Bragg Gratings (FBGs) into phosphate glass fibers using UV light and a phase mask technique. With this new manufacturing technique, fiber lasers can be created as single monolithic...

All-Fiber Multicore Fiber Laser Devices
Researchers at the University of Arizona have developed a compact, power-scalable, alignment-free fiber laser that takes a new approach to stabilizing phase-locked operation of multi-core fiber lasers by completely removing all free space optical components. This high-brightness, all-fiber laser package uses passive optical fiber spliced at both ends...

Cytotoxicity-Based Genetic Selection for Targeted Drug Screening
Applications Screening method for drug discovery and investigating protein-protein interactions. Technical Summary Drug discovery is typically dependant on screening methods that involve negative selection, or the death of cell cultures when exposed to a specific drug. This invention, a cytoxicity-based genetic selection method (TOXSEL), introduces...
