Test organisms were subjected to varying amounts of sulfide, carbonate, chloride and sulfate salts of lead, zinc and cadmium mixed in hard, alkaline waters typical to this region. Median lethal concentrations were calculated using nominal versus measured metal concentrations. Measured metal concentrations included four different metal fractionation (extraction/filtration) techniques at different pH levels which included "dissolved", …

Evaluation Of Subdivision Methods Used In Octree Ray Tracing Algorithms, Scott Brown

Theses

The non-uniform spatial subdivision technique refined by Andrew Glassner [Glassner 1984] minimizes facet intersection tests (i) by automatically generating a density dependent spatial hierarchy of facet regions (called an octree) and (ii) by only testing facets in regions along the path of the ray. Past research has addressed optimization of the octree ray tracing process by separately improving both the octree traversal method and facet intersection algorithms. This author attempted to further improve the overall approach by attempting to identify new octree construction methods that would decrease the number of traversals required to render the scene. This research focused on …

The Feasibility Of Atm Operations Over High Frequency Radio And The Viability Of The Atm/Hf Architecture, Paul Giovanni

A Comparison Of Highly Efficient Iterative Linear Solvers, Akbar Chowdhury

Theses

A number of iterative techniques have recently been developed which are extremely efficient at solving systems of linear equations. Of these methods probably the most recognized is the Conjugate Gradient Method (CG). This is an extremely efficient solver and has been used successfully for a number of years now. A newer method proposed initially by Davidson [1] is studied in this paper. This method has proven itself in terms of efficiency by solving the same system (of order 2000) that was solved by the CG method. It converged in approximately 40 iterations, taking less than five minutes to do so[5], …

The ‘‘Foliage Is The Fruit’’ Hypothesis: Complex Adaptations In Buffalograss (Buchloe Dactyloides), John Ortmann, Walter H. Schacht, James L. Stubbendieck, Dennis R. Brink

Department of Agronomy and Horticulture: Faculty Publications

Buffalograss (Buchloe dactyloides) has been described as an excellent fit for Janzen’s ‘‘Foliage is the Fruit’’ (FF) hypothesis, which suggests that large grazing animals ingest and later disperse seeds of some herbs when consuming their foliage. We tested this hypothesis by feeding buffalograss burs and legume seeds to ruminally fistulated beef steers. Our objectives were to determine (1) rumen residence times of buffalograss burs, free buffalograss caryopses and legume seeds; (2) total tract residence times for the three types of propagules; (3) percentage propagule survival after passage and (4) germinability of fed and unfed burs and caryopses. Bur …

Error-Correcting Codes Associated With Generalized Hadamard Matrices Over Groups, Iem H. Heng

Mathematics & Statistics Theses & Dissertations

Classical Hadamard matrices are orthogonal matrices whose elements are ±1. It is well-known that error correcting codes having large minimum distance between codewords can be associated with these Hadamard matrices. Indeed, the success of early Mars deep-space probes was strongly dependent upon this communication technology.

The concept of Hadamard matrices with elements drawn from an Abelian group is a natural generalization of the concept. For the case in which the dimension of the matrix is q and the group consists of the p-th roots of unity, these generalized Hadamard matrices are called “Butson Hadamard Matrices BH(p, q)”, …

Book Review: Lessons From Reconstruction For Libertarians: Betrayal And Illusion In The Struggle For Real Equality No Easy Walk To Freedom: Reconstruction And The Ratification Of The Fourteenth Amendment By James E. Bond, Henry W. Mcgee, Jr.

Seattle University Law Review

With regard to the struggles of the newly freed slaves, Dean Bond's study of the Reconstruction legislatures endorses the views of contemporary historians. These historians do not blame the freedman for failure to forge lasting instruments of liberation, instruments that might have transformed the formal equality promised by emancipation into a social order free of the stigmatizing racial oppression upon which American slavery, segregation, and racial oppression has been premised. Diligently researched and written, the book is of significant interest because of the coincidence of the author's empathy with Afro-Americans and his unwavering and unequivocal affirmation of racial equality, principles …
