    Notes: Abstract Computer image-processing techniques are often used in, for example, the analysis of thin sections of reservoir rock because of the large amounts of data contained in a single digitized section image. Erosion and dilation are operations frequently used in this type of work to iteratively smooth the pore perimeters and in estimating pore radii, volume, and roughness. Because of the size of each image, erosion and dilation of pore complex images is a time-consuming process. A recent method calledglobal erosion is much faster whether used on small, in-memory images or large images residing on a file. Use of this method should allow processing of larger images, or a greater number of small images, than do the standard methods.

    Description: A Miniaturized Pointing Mount (MPM) for Spacelab missions is defined and simulation results are described. This mount is proposed to complement the Spacelab Instrument Pointing System (IPS). It uses the same mount isolator concept as the Spacelab IPS but is much more efficient and economical for the accommodation of small shuttle payloads. The MPM is built from star tracker assemblies left over from the Apollo Telescope Mount program thereby assuring low cost and development risk. Simulation results indicate a high level of instrument stability can be expected. The short development time of the MPM would permit it to serve as a precursor to the Spacelab IPS for verifying critical new concepts such as the mount isolation and hold down mechanisms.
