(Phys.org) —If you've been lucky enough to catch all the green lights as you drive down a busy street, you may have been benefiting from intentional synchronization called a "green wave." The green wave concept has been ...
(PhysOrg.com) -- In urban areas, there’s almost always more than one way to get somewhere, but often it’s difficult to predict which road will be fastest. In an attempt to improve traffic flow and decrease congestion, ...
(PhysOrg.com) -- As highway traffic increases, you'd probably expect a traffic jam, where vehicles slow down due to the high density. While traffic jams are a common occurrence on our highways, high density traffic has completely ...
(PhysOrg.com) -- Two studies have just been published that may help improve traffic flows. The first, presented as a Santa Fe Institute working paper for September, concluded that if traffic lights responded to measured traffic ...
In 1883, Osborne Reynolds injected ink into water in a short, clear pipe to observe its movement. His experiments showed that as the input water velocity increased, the flow went from laminar (smooth and predictable) to turbulent ...

On the highway of heat transfer, thermal energy is moved by way of quantum particles called phonons. But at the nanoscale of today's most cutting-edge semiconductors, those phonons don't remove enough heat. That's why Purdue ...
