AnzMeador Analyses of the fragmentation (due to explosions and collisions) of spacecraft and rocket bodies in low Earth orbit (LEO) have been performed this year at NASA/JSC. The overall goals of this study have been to achieve a better understanding of the results of fr...

Increased access to very large astronomical databases, the use of large format detectors and other developments in observational astronomy have the potential to overwhelm the capacity of most astronomers to analyze data unless new approaches to data reduction are found. This paper reports the initial progress in creating an expert system to assist in the reduction of scientific data. This syste...

Generically, a probability distribution corresponds to a function p(x) which defines the likelihood for random variable x. The likelihood that for which the probability of the random variable falling in a small interval dx centered on the value x0 is p(x0)dx. The distribution describes the probability density which, when integrated, yields the probability of x falling between any two values: P ...
