The statistical properties embedded in visual stimuli from the surrounding environment guide and affect the evolutionary processes of human vision systems. There are strong statistical relationships between co-located luminance/chrominance and disparity bandpass coefficients in natural scenes. However, these statistical relationships have only been deeply developed to create point-wise statisti...

The software engineering tools historically used to examine faults can also be used to examine vulnerabilities and the rate at which they are discovered. I discuss the challenges of the collection process and compare two sets of vulnerability characterization criteria. I collected fifty-four months of vulnerability data for OpenBSD 2.2 and applied seven reliability growth models to the two data...
