Numerical modeling of second order partial differential equations with variable coefficients governing the flow of fluids in heterogeneous media
(1968)
A numerical simulation model was developed for studying the effects of element injection upon fluid flow behavior in non-uniform underground reservoirs. The model has the capability of tracking up to three phases with ...
A review of the large species of Artibeus (Chiroptera: Phyllostomatidae) from western South America
(1961)
The fruit-eating bats of the genus Artibeus inhabit an extensive geographic area from northern Mexico to southern South America. Despite their importance in the ecology of the New World tropics and their relatively early ...
Simulation and statistical quality control for water pollution abatement
(1962)
Increasing water pollution problems and increasing public demands for high quality water make it imperative that regional water quality systems be properly managed. To manage the stochastic nature of a regional water quality ...
Solutions of the Lenard-Balescu equation for drifted plasmas
(1962)
The usefulness of one-dimensional plasma models is often questioned because of the absence of lateral effects that are considered to be important in three dimensions. However, one-dimensional models are much more tractable ...
The impact of changes in the money stock on the agricultural sectors of the economies of the United States and other selected countries
(1962)
This study gauges the impact of changes in the money stock on the income of the agricultural sector of the United States and its expenditure on capital equipment. Test equations which relate nominal money stock are derived ...
Equilibrium and catalytic studies of some cobalt (II) chelate oxygen carriers
(1962)
The cobalt (11) chelates of ethylenediamine, diethylenetriamine, triethylenetetraamine, and tetraethylenepentaamine in aqueous solution are studied by potentiometric pH and oxygen absorption measurements. The chelates ...
A prediction model for the variation of the thermal structure in the ocean surface layer
(1968)
A numerical model is developed for the simulation of changes of the vertical temperature distribution within the ocean surface layer as a function of time. For imposed meteorological conditions characteristic of winter and ...
On the endomorphism monoids of Boolean algebras and distributive lattices
(1967)
This work is concerned with some questions which arise in the study of endomorphism monoids of Boolean algebras and finite distributive lattices. It is a well known fact that the automorphism group does not characterize a ...
