This paper briefly describes the current implementation status of an intelligent information retrieval system, MARIE, that employs natural language processing techniques. Descriptive captions are used to identify photographic images concerning various military projects. The captions are parsed to produce a logical form from which nouns and verbs are extracted to form the primary keywords. User ...

Given n weighted records distributed evenly among a p-processor hypercube, p n, we present ee-cient parallel algorithms for solving the weighted selection and related problems in the coarse-grain weak-hypercube model. A special case of the weighted selection problem, in which all the weights are equal, is known as the (unweighted) selection or order statistics problem. Our algorithms seek to mi...

Nanocrystalline (nc) materials can be defined as solids with grain sizes in the range of 1–100 nm. Contrary to coarse-grained metals, which become more difficult to twin with decreasing grain size, nanocrystalline face-centered-cubic (fcc) metals become easier to twin with decreasing grain size, reaching a maximum twinning probability, and then become more difficult to twin when the grain size ...

A 2-year field experiment was conducted on maize (Zea mays L.) to explore effective ways to decrease soil CO2 emissions and increase grain yield. Treatments established were: (1) no mulching with urea, (2) no mulching with controlled release fertiliser (CRF), (3) transparent plastic-film mulching (PMt) with urea, (4) PMt with CRF, (5) black plastic-film mulching (PMb) with urea, and (6) PMb wit...

This paper proposes a 3-dimensional coarse grain model of microtubules and treats the tubulin monomer as a sphere of multiple patches, with parameters chosen to yield experimental values of bending and stretching stiffness. The model has demonstrated the ability to produce the bistability of tubulin sheets, elastic deformation near the tip, and cracking and peeling of protofilaments. This model...

In this paper we present top down and bottom up methods for generating coarse grain dataaow or mul-tithreaded code, and evaluate their eeectiveness. The top down technique generates clusters directly from the intermediate data dependence graph used for compiler optimizations. Bottom up techniques coalesce ne-grain dataaow code into clusters. We measure the resulting number of clusters executed,...
