Le Sacre du Big Red

Red light for red-light cameras? A meta-analysis of the effects of red-light cameras on crashes.

A meta-analysis has been conducted on the effects of red-light cameras (RLCs) on intersection crashes. The size and direction of results reported from studies included in the meta-analysis are strongly affected by study methodology. The studies that have controlled for most confounding factors yield the least favourable results. Based on these studies, installation of RLCs leads to an overall i...

RED in a Different Light

Packet networks require queues (buffers) to absorb short term arrival rate fluctuations. Yet network implementors have always observed that queues at bottlenecks tend to fill and stay filled, which contributes extra delay and removes the ability to absorb bursts. In [1] Floyd and Jacobson proposed the RED (Random Early Detection) active queue management algorithm. RED is simple, robust and quit...

Update on Red-Light Sensing The Red Side of Photomorphogenesis

The importance of light to normal plant growth and development cannot be overstated. As sessile photoautotrophs, plants depend on efficient light capture to compete and reproduce successfully within a relatively restricted geographical realm. For this purpose, these organisms have evolved very sophisticated sensory networks for monitoring the status of several important features of their illumi...
