Power shift: University of Toronto researcher applies AI to monitor city's electrical grid
July 21, 2017 08:12 AM - University of Toronto

From indoor lighting to outdoor street lamps, our world is made brighter by artificial light. But the light that we perceive to be constant, actually fluctuates.

A University of Toronto computer scientist and researchers from the Technion-Israel Institute of Technology are studying electrical grids for cities, creating a camera that records the city's lights at a slower speed to get more accurate readings of changing voltages at particular locations.

Scientists Uncover Biogeochemical Controls on Occurrence and Distribution of PACs in Coals
July 21, 2017 09:56 AM - University of Science and Technology of China

The organic matter in coal contains polycyclic aromatic compounds (PACs) of varying quantities in diverse soluble and insoluble forms. PACs in coal are of special interest for organic geochemical studies as they have been successfully used as biological marker compounds (biomarkers) and indicators of thermal maturity.

However, challenges exist when applying PACs in understanding the organic geochemistry of coal. For example, what are the sources of PACs in coals? How do they transform during the long-term coal-formation history? Is there any regular relationship between the PAC and macro-molecular structural changes?
