A common basis is suggested for the optical flow estimation approaches of Nagel (1983), Haralick and Lee (1983) and Tretiak and Pastor (1984). Based on a discussion of these approaches, an exact solution for the system of partial differential equations proposed by Horn and Schunck (1981) is given at gray value corners and extrema. The insight gained by this solution results in a modification of...

The studies under review are new in that they come from a conference on Hooke that took place in 1987. Recency does not guarantee freshness, however, and, with a few exceptions, the studies only, though competently, add epicycles to the known world of Re...

Goodness of Fit (GOF) tests for non-location/scale families of distributions have not been studied extensively. Previous research has focused on the case where the distribution function is either completely specified or a member of a location/scale family. A new test statistic, which resembles a regression sum of squares, is developed and its properties investigated in this dissertation. This s...

The work simply could not have been done without them. We also wish to thank Jennifer Miller and two anonymous reviewers for helpful comments on earlier drafts of the manuscript, and Robert Lickliter for the invitat...

Though emotions are often morally appraised and judged in everyday life among individuals, within the moral responsibility community this comes in direct conflict with the commonly held belief that moral responsibility requires some form of volitional control. Angela Smith argues that volitional control is not a key factor in responsibility but depends upon an agent’s evaluat ive judgments. She...

In recent years, it has become increasingly fashionable to attribute a myriad 0f our economic and social difficulties to excessive government regulation. If we are to believe the rhetoric, government regulation is partly or largely to blame for soaring inflation, lagging growth in GNP, declining productivity growth, the decline in the value of the dollar, and even general reductions in the anim...
