A hydrogeologic database for stochastic groundwater modeling with hydrogeologic environment-specific applications
(1989)
The development of a method to restrict the land disposal of hazardous waste is an area of great concern for the United States Environmental Protection Agency. A proposed method is to determine allowable concentrations, ...
Post audit modeling of remedial clean up of a chlorinated hydrocarbon plume
(1988)
In 1984, a computer modeling study of a groundwater recovery system was conducted on a trichloroethylene (TCE) plume at an industrial site, using the USGS Solute Transport model. Since that time, the recovery well system ...
The acquisition, signal processing and analysis of epicardial surface electrograms from rabbit heart
(1989)
The activation sequence on the epicardial surface of the in vivo rabbit ventricle has been recorded and analyzed under conditions of normal sinus rhythm and controlled hemodynamic load. Data for the analysis was gathered ...
Automatic mesh generation of two-dimensional objects
(1988)
An approach for the fully automatic generation of two-dimensional finite element meshes is presented. The method follows from the basic concept of the quadtree encoding technique with the specific modifications made to ...
A nonlinear isoparametric contour plotting and filling algorithm
(1988)
An interactive isoparametric contour plotting and filling program, ISOCON, is developed for use with finite element meshes using common two-dimensional triangular and quadrilateral elements. The program uses the local ...
Near-optimum guidance schemes for abort landing flight in a windshear
(1988)
In this thesis, near-optimum guidance schemes for abort landing trajectories in a windshear are investigated. These near-optimum guidance schemes are based on the properties of the optimum trajectories. The survival ...
Development of a strain softening constitutive model for rock
(1988)
A plasticity based constitutive model with two yield surfaces is developed to model the nonlinear axial and volumetric behavior observed for rocks in triaxial compression. The failure surface is allowed to soften at low ...
A correspondence between Scheme and the lambda(,upsilon)-CS-calculus
(1989)
We study the relationship between the programming language Scheme and the $\lambda\sb{v}$-CS-calculus. To this end, we define a correspondence between Scheme and $\Lambda\sb{CS}$-terms--the language of the calculus--where ...
