Using Data Loss and Duplication Maps to study data use associated with nearest-neighbor resampling

Creator:: Perigny, Mathew
Abstract:: Nearest-neighbor resampling is a common procedure used by cartographers to reproject raster data sets. This type of resampling is useful because it retains the data from the original raster data set. However, during nearest-neighbor resampling some of the original data will be lost as it is reprojected, while other data...

Locating villages in the floods : the use of RADARSAT imagery in the flood hazard management in Bangladesh

Creator:: Petry, Heather N.
Abstract:: Bangladesh lies almost entirely on the delta of three major rivers: the Padma (the Ganges), the Jamuna (the Brahmaputra), and the Meghna. A considerable portion of Bangladesh has been repeatedly devastated by floods associated with cyclonic storm surges along its coastal islands and riverine flooding along the rivers traversing the...

Discrete compression web bracing design for light-frame wood trusses

Creator:: Waltz, Miles E.
Abstract:: As part of a roof framing system, light-frame wood trusses often require lateral bracing to reduce the effective length for flexural buckling of compression web members. This observational research investigates the design requirements for discrete compression web bracing intended to provide such lateral support. Four simple brace analysis methods based...

Measurement of the rates of reductive dechlorination of chlorinated phenols

Creator:: Nicholson, David K.
Abstract:: Knowledge of a compound's degradation pathway is crucial to the assessment of risk at contaminated sites. Pentachlorophenol and its metabolic products can serve as model compounds to study the fate and transport of halogenated aromatic compounds in the environment. Acclimation of anaerobic sewage sludge to pentachlorophenol produced a microbial consortium...

Evaluation of different monitoring strategies for public health protection : harmful algal bloom surveillance at Devils Lake, Lincoln City, OR

Creator:: Hitchko, Kara L.
Abstract:: Cyanobacteria are photosynthetic bacteria capable of producing toxins, including complex cyclic peptides called microcystins. Hazardous cyanobacterial blooms are an emerging public health concern and are monitored throughout Oregon in various recreational and drinking water bodies. Oregon has been proactive and responsive to the problems associated with toxic cyanobacterial blooms, but...

Broadening the scope of the modified-Julia reaction : a mild and stereoselective method for the synthesis of (Z)-configurated α,β-unsaturated lactones

Creator:: Giesbrecht, Heath Eugene
Abstract:: An intramolecular variant of the modified-Julia olefination was demonstrated by the synthesis of α,β-unsaturated lactones in a mild and (Z)-selective fashion. The lynchpin reagent (benzothiazol-2-sulfonyl) acetic acid was synthesized in a straightforward fashion in 86% overall yield from commercially available 2-mercaptobenzothiazole via conversion to ethyl (benzothiazol-2-ylthio)acetate by base mediated alkylation...

Total synthesis of sparteine alkaloids from a common tetraoxobispidine intermediate

Creator:: Melbardis, John
Abstract:: In previous work (Blakemore et al. Org. Lett. 2005, 7, 4721; Heterocycles 2006, 70, 609), successful elaborations of the lupine alkaloids (±)-α-isosparteine (dl-2) and (±)-β-isosparteine (dl-3) were realized from a common tetraoxobispidine precursor, 3,7-diallyl -2,4,6,8-tetraoxo-3,7-diazabicyclo[3.3.1]nonane (93). Herein, the tetraoxobispidine approach to lupine alkaloids was extended to a total synthesis of...

The Effects of Temperature on Electrical Resistivity Measurements of Concrete

Creator:: Coyle, Alex T.
Abstract:: Measuring resistivity as a method to calculate formation factor is becoming a popular way to evaluate transport properties of concrete. Resistivity measurements are dependent on multiple factors including the resistivity of the pore solution, leaching effects, the degree of saturation of the specimen, the age of the specimen (degree of...

Passive source tracking from spatially correlated angle-of-arrival data

Creator:: Haisch, Hansjoerg
Abstract:: This thesis presents a simulation technique for the post-detection of a point-source trajectory in an isotropic, stationary random medium. The two-dimensional source location is estimated from spatially correlated angle-of-arrival data which are collected simultaneously at two sensor positions. We assume that the data are collected at discrete, constant time intervals...
