Winter could pose solar farm 'ramping' snag for power grid

By adding utility-scale solar farms throughout New York state, summer electricity demand from conventional sources could be reduced by up to 9.6% in some places.

Church, couch, couple: Social psychological connections between people and physical space

Societies and people have reshaped the world many times over. From building cities and communities that live within them, to the smaller changes in a person's home or place of worship, people influence their space. Benjamin Meagher, a social psychologist at Hope College, argues that the space people shape, also shapes the individual, and that social psychology must take an "ecological" view of people in their environment.

Three convolutional neural network models for facial expression recognition in the wild

Two researchers at Shanghai University of Electric Power have recently developed and evaluated new neural network models for facial expression recognition (FER) in the wild. Their study, published in Elsevier's Neurocomputing journal, presents three models of convolutional neural networks (CNNs): a Light-CNN, a dual-branch CNN and a pre-trained CNN.

New organic flow battery brings decomposing molecules back to life

After years of making progress on an organic aqueous flow battery, Harvard University researchers ran into a problem: the organic anthraquinone molecules that powered their ground-breaking battery were slowly decomposing over time, reducing the long-term usefulness of the battery.

U.S. Postal Service mail, packages are headed to Dallas by self-driving truck

Before letters end up in your mailbox and packages land on your doorstep, many travel hundreds or thousands of miles in the back of a truck. Now, the United States Postal Service is testing what it would take to shuttle that cargo without a driver in the front seat.

Release of solar panel dataset helps cities make power grids more safe, reliable

Solar power researchers have traditionally only used the power measurements from single residential solar photovoltaic (PV) systems to estimate the power generated within a city. But one installation isn't a good representation of all the rooftops in the city, where the time of day, panel direction, and shade cast by trees and clouds affect power production.
