Science and computing
Article Abstract:
Computers continue to be of immense value to both the experimental-observational and theoretical sides of science, but the scientist must be aware that the degrees of complexity being resolved at supercomputer levels may result in unexpected and unbounded errors due to the inability to accurately discretize the models of many of the problems being studied. State-of-the art computers will continue to be used to solve basic problems in scientific fields, though computing's precise role will continue to be reassessed. One primary driving factor in the growing use of computers is the exponential increase in power and complementary decrease in cost, contrasted with slow growth in power and rapid growth in costs of other scientific instruments.

Computing local minima and maxima of digital images in pipeline image processing systems equipped with hardware comparators
Article Abstract:
An efficient technique for computing minima (maxima) values of gray levels of pixels within rectangular windows is described. The technique is appropriate for pipeline image processing systems having processor equipped with hardware comparators. Minima and-or maxima of gray levels within M x N windows requires log N + log M passes throughout the Digital Video Processor where X denotes the smallest integer larger than X.
