Overcoming structural uncertainty in computer models
Philadelphia, PA (SPX) Apr 03, 2014 -
A computer model is a representation of the functional relationship between one set of parameters, which forms the model input, and a corresponding set of target parameters, which forms the model output. A true model for a particular problem can rarely be defined with certainty. The most we can do to mitigate error is to quantify the uncertainty in the model.
In a recent paper published in ...

Video shows apparent meteor whiz by skydiver
Oslo, Norway (UPI) Apr 4, 2013 -
The chance of being hit by a meteorite is one in 20 trillion. But in 2012, one skydiver got closer than most.
In a newly released video - captured by the helmet cam of Norwegian skydiver Anders Helstrup - what appears to be a stone can bee seen hurtling past Helstrup just as he opens his chute.
Some skeptics have theorized that the object is actually a pebble that got wrapped u ...
