3d Reconstruction Using Multi-View Imaging System, Conglin Huang
3d Reconstruction Using Multi-View Imaging System, Conglin Huang
University of Kentucky Master's Theses
This thesis presents a new system that reconstructs the 3D representation of dental casts. To maintain the integrity of the 3D representation, a standard model is built to cover the blind spots that the camera cannot reach. The standard model is obtained by scanning a real human mouth model with a laser scanner. Then the model is simplified by an algorithm which is based on iterative contraction of vertex pairs. The simplified standard model uses a local parametrization method to obtain the curvature information. The system uses a digital camera and a square tube mirror in front of the camera …
Use Of Surface Geophysical Techniques To Locate A Karst Conduit In The Cane Run - Royal Spring Basin, Kentucky, Ganesh N. Tripathi
Use Of Surface Geophysical Techniques To Locate A Karst Conduit In The Cane Run - Royal Spring Basin, Kentucky, Ganesh N. Tripathi
University of Kentucky Master's Theses
Groundwater flow in karst terrains is difficult to map because it can be concentrated through conduits that do not necessarily coincide with the surface features. We applied electrical resistivity (ER) and self-potential (SP) techniques at three sites to locate an inferred trunk conduit feeding a major spring in the Inner Bluegrass region of Kentucky. Royal Spring is the primary water supply for the city of Georgetown; the upper part of its basin coincides with the Cane Run watershed. ER and SP profiles were perpendicular to the inferred trunk conduit orientation. ER profiles (972 m total length) were measured using a …
Bedrock Mapping Of The Winchendon (1:25,000) Quadrangle (Ma-Nh): Evidence For Discontinous Deformation Along The Bronson Hill-Central Maine Boundary Zone, Timothy M. O'Brien
Bedrock Mapping Of The Winchendon (1:25,000) Quadrangle (Ma-Nh): Evidence For Discontinous Deformation Along The Bronson Hill-Central Maine Boundary Zone, Timothy M. O'Brien
University of Kentucky Master's Theses
Bedrock geology of the Winchendon quadrangle is divided into two zones based on structures and lithology. The eastern zone consists of tightly folded Silurian Rangeley and Paxton metasediments and pegmatites. Planar, NNE-SSW striking, W dipping foliations are characterized by alternating phyllosilicate-rich and leucosome layers. Fold axes of tight to isoclinal upright and recumbent folding are parallel to SSW-NNE shallowly plunging sillimanite, quartz and muscovite lineations. In the western zone Rangeley schists were intruded by Devonian Hardwick and Coys Hill and Fitzwilliam plutons. Planar NNE-SSW striking foliations dip shallowly to steeply west. Fold axes of tight-to-isoclinal asymmetric to recumbent folds plunge …
Structural Geology Of The Transylvania Fault Zone In Bedford County, Pennsylvania, Elizabeth Lauren Dodson
Structural Geology Of The Transylvania Fault Zone In Bedford County, Pennsylvania, Elizabeth Lauren Dodson
University of Kentucky Master's Theses
Transverse zones cross strike of thrust-belt structures as large-scale alignments of cross-strike structures. The Transylvania fault zone is a set of discontinuous right-lateral transverse faults striking at about 270º across Appalachian thrust-belt structures along 40º N latitude in Pennsylvania. Near Everett, Pennsylvania, the Breezewood fault terminates with the Ashcom thrust fault. The Everett Gap fault terminates westward with the Hartley thrust fault. Farther west, the Bedford fault extends westward to terminate against the Wills Mountain thrust fault. The rocks, deformed during the Alleghanian orogeny, are semi-independently deformed on opposite sides of the transverse fault, indicating fault movement during folding and …
Matrix Geochemistry And Phytophthora Occurrence On Reforested Mine Lands In Appalachia, Kathryn M. Ward
Matrix Geochemistry And Phytophthora Occurrence On Reforested Mine Lands In Appalachia, Kathryn M. Ward
University of Kentucky Master's Theses
At the Bent Mountain surface mine, Pike County, Kentucky, a study has been ongoing since 2005 to assess the influence of various types of loose-graded mine spoils on water quality and forest establishment. Six research plots consist of two replicates of brown weathered sandstone, gray unweathered sandstone, and mixed brown sandstone, gray sandstone, and shale that were emplaced according to Forestry Reclamation Approach criteria. A series of analyses was initiated in 2007 to examine influence of spoil matrix composition on sulfate and carbonate geochemistry of infiltrated waters, as well as to investigate the occurrence of Phytophthora, a group of …
Variation In C/P Ratios In Devonian-Mississippian Marine Shales: Testing The Productivity-Anoxia Feedback Model, Brian T. Scott
Variation In C/P Ratios In Devonian-Mississippian Marine Shales: Testing The Productivity-Anoxia Feedback Model, Brian T. Scott
University of Kentucky Master's Theses
Carbon/phosphorus ratios for late Devonian-early Mississippian marine black shales along a transect from the Illinois Basin, across the Cumberland Saddle, and into the Appalachian Basin were evaluated to assess the role of productivity in organic carbon accumulation. Phosphorus is a key limiting nutrient for biological productivity in marine environments and may be regenerated preferentially relative to organic carbon, the amount of regeneration possibly being related to bottom-water anoxia. A positive feed-back mechanism (more specifically, productivity-anoxia feedback or PAF) has been proposed between water-column anoxia, high benthic regeneration of phosphorus, and marine productivity. This regeneration of phosphorus under anoxic conditions and …
