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 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 ...
Ecological observations on penaeid shrimp in Mobile Bay, Alabama
(1968)
Twelve stations in Mobile Bay were sampled monthly with an otter trawl for 27 consecutive months. Twelve shore and ten nearshore stations were sampled concurrently. All shrimp taken were measured. Water salinities and ...
Perturbation theory based on exactly localized states
(1968)
We investigate the usefulness of a perturbation theory which starts from exactly localized states. We find that for various single particle problems, the ground-state energy as a function of the effective coupling strength ...
Achievement of sixth-grade pupils in modern mathematics as related to their teachers' mathematics preparation
(1968)
Statement of Problem [line break] The purpose of this study was to determine whether a change in the mathematics preparation of sixth-grade teachers would affect a change in the arithmetic achievement of their pupils. ...
