GALENA: Tabular DCG Parsing for Natural Languages
We present a deenite clause based parsing environment for natural languages, whose operational model is the dynamic interpretation of logical push-down automata. We attempt to brieey explain our design decisions in terms of a set of properties that practical natural language processing systems should incorporate. The aim is to show both the advantages and the drawbacks of our approach.
متن کاملGalena Lead Isotope Model for Vancouver Island*
This paper demonstrates how a galena lead isotope model can be used to make decisions about the age and origin of ore deposits on Vancouver Island. To build this model we draw on the galena data of Table 1-9-1 (compare Andrew and Godwin, in press a, b, c and Godwin et al., 1988). Galena lead isotope data from Vancouver Island do not show a systematic evolution with time. Therefore they cannot b...
متن کاملEffects of Annealing on Deformation Textures in Galena
Experimental annealing of galena samples with known deformation histories shows that this mineral has the necessary properties to be a valuable source of information about low-grade deformational environments. Annealed galena displays recovery and/or recrystallization features dependent upon the type of texture inherited from the tectonic event, which in turn is closely linked to deformation te...
متن کاملHydrophobic Flocculation of Galena Fines in Aqueous Suspensions.
The hydrophobic flocculation of galena fines induced by potassium amyl xanthate (PAX) in aqueous suspensions has been studied using laser diffraction, electrophoretic light scattering, contact angle, and microflotation measurements. The measurements were performed on <2 µm, 2-5 µm, 5-10 µm, and <30 µm size galena by varying several parameters, including PAX concentration, pH, original particle ...
متن کاملINTERPRETATION OF GALENA LEAD ISOTOPES FROM TEXADA ISLAND* (92F) By Colin
Texada Island (Figure 2-5-1) is with.in Wrangellia. Calcalkaline plutonism of the Coast plutonic complex is superimposed on this terrane. The northern part of the island is made up mainly ct basaltic amygdaloidal flows and pillovr lavas of the ?exad1 Formation (Karmutsen Fbrmation) overlain by massibe grqi limestone and white marble of the Marble Bay Fonnatio I (Quatsino Formation). These Upper...
