But for drones with four propellers - also known as quadcopters - the failure of one motor is a bigger problem. With only three rotors working, the drone loses stability and inevitably crashes unless an emergency control strategy sets in. Researchers at the University of Zurich and the Delft University of Technology have now fo...

 E-Mail Skoltech researchers have found a way to use chemical sensors and computer vision to determine when grilled chicken is cooked just right. These tools can help restaurants monitor and automate cooking processes in their kitchens, and perhaps one day even end up in your 'smart' oven. The paper detailing this research results, supported by a Russian Science Foundation grant, was published in the journal Food Chemistry. How do you tell that chicken breast on your grill is ready for your plate? You probably look at it closely and smell it to make sure it is done the way you like it. Howe...

The equipment will be used in support of a grant he received in August from the Naval Surface War Center-Dahlgren Division (NSWC-DD) to study the high-voltage dielectric insulation properties of epoxy and additively manufactured materials. Dielectric materials can transmit electric force without condu...
