Parka on Mimd-supercomputers
We have ported the SIMD Parka knowledge representation system to generic MIMD machines. The system has been recoded in C and supported using runtime optimization packages developed in the High Performance Systems Software Laboratory at the University of Maryland. New \scanning" algorithms have been developed for inheritance and recognition inferences. These algorithms have been tested with both...
متن کاملNew Bioactive Diterpenoid from Euphorbia decipiens
One new diterpene ester with a tricyclic lathyrane-or myrsinol-type skeleton has been isolated fromEuphorbia decipiensBoiss. &Buhse. In addition to one new, the known constituents -amyrin, -amyrin acetate, methyl (2,4-dihydroxy-3-formyl-6-methoxy) phenyl ketone (2), and 1,1-bis (2,6-dihydroxy-3-acetyl-4-methoxyphenyl)methane (3) have been isolated from the same source. The structure elucidation...
متن کاملPARKA: A System for Massively Parallel Knowledge Representation
PARKA is a frame-based knowledge representation system implemented on massively parallel hardware--the Connection Machine (CM-2). PARKA provides a representation language consisting of concept descriptions (frames) and binary relations on those descriptions (slots). The system is designed explicitly to provide extremely fast property inheritance inference capabilities. In particular, PARKA can ...
متن کاملForMAT and Parka: A Technology Integration Experiment and Beyond
This report describes a Technology Integration Experiment (TIE) between the University of Maryland and The MITRE Corporation which was undertaken as part of the (D)Arpa/Rome Laboratory Planning Initiative (ARPI). This work led to an integration of the UM Parka-DB tool into the MITRE ForMAT transportation planning tool.
متن کاملFirst natural urease inhibitor from Euphorbia decipiens.
Three new diterpene esters with a myrsinol-type skeleton have been isolated from Euphorbia decipiens BOISS. & BUHSE. The structure elucidation of the isolated compounds was based primarily on two-dimensional (2D)-NMR techniques including correlation spectroscopy (COSY), heteronuclear multiple quantum coherence (HMQC), heteronuclear multiple bond correlation (HMBC) and nuclear Overhauser effect ...
