Fabrication of metal-insulator-semiconductor photoelectrodes
Background Photoelectrochemical (PEC) water splitting is a promising technology for converting solar energy into clean and storable chemical energy. In PEC cells, semiconductors play a key role in absorbing photons from the light source to create mobile charge carriers. Various semiconductor materials have been studied for the high-performance PEC cells,...

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...

Exploring Personal Attributes from Publicly Available Interactions to Secure Users’ Privacy
As social networking becomes more popular, sensitive personal information seems to become much more readily available on the web. Although some social networks have privacy settings the user can change, some user-created data is simply unchangeable, and thus, remains public. Websites inadvertently store information such as links clicked on, liked, favorited,...

Leveraging Social Foci for Information Seeking in Social Media
People frequently use social media to find information that may not be readily available from search engines or to request input from their peers. However, the search technology built into conventional social media platforms is not designed for information retrieval purposes. Since content is not archived, it is difficult to find answers to similar...

Unsupervised Streaming Feature Selection in Social Media
The explosive and viral nature of social media creates massive amounts of high-dimensional data. Features such as hashtags, keywords, or slang words are created every day and quickly become popular within a short period of time. However, social media data is not fully structured and its features are usually not predefined. One way to resolve this problem...

CrossFire: Cross Media Joint Friend and Item Recommendations
Background Recommendations of user-to-user relationships (“friends”) and items (e.g., products, services) have become integral to the social media experience. When implemented effectively, both the user and the platform gain value. Unlike established sites however, newly launched social media sites lack the historical data typically necessary...

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...
