Eyes-off/hands-off means that the driver can stop monitoring the system, leaving the system in full control. Eyes-off requires that no errors be reproducible (not triggered by exotic transitory conditions) or frequent, that speeds are contextually appropriate (e.g., 80 mph on limited-access roads), and that the system handle typical maneuvers ...
The great apes (Hominidae) show some cognitive and empathic abilities. Chimpanzees can make tools and use them to acquire foods and for social displays; they have mildly complex hunting strategies requiring cooperation, influence and rank; they are status conscious, manipulative and capable of deception; they can learn to use symbols and understand aspects of human language including some ...
An Australian sculptor has created a model of what the human body would have to look like to survive a car crash -- and it's the stuff of nightmares. The artist, Melbourne-based Patricia Piccinini ...
The flicker fusion threshold, also known as critical flicker frequency or flicker fusion rate, is the frequency at which a flickering light appears steady to the average human observer. It is a concept studied in vision science, more specifically in the psychophysics of visual perception. A traditional term for "flicker fusion" is "persistence ...
Researchers have found that molecules and microorganisms both inside and outside our bodies are going through dramatic changes, first at about age 44 and then again when we hit 60. Those ...
When you’re not up to getting too physical, there are other ways to give your hand-eye coordination a boost. Here are some options: Bouncing a ball. Playing catch. Playing video games. Learning ...
Another quantum effect that predicts the occurrence of faster-than-light speeds is called the Hartman effect: under certain conditions the time needed for a virtual particle to tunnel through a barrier is constant, regardless of the thickness of the barrier. [50] [51] This could result in a virtual particle crossing a large gap faster than ...
The two ages with the largest molecule and microbe changes, scientists found, occur when a person is in their mid-40s and early 60s. “We expected the changes in the 60s because this is when ...
