Sharing A Landscape: The Construction Of Sense Of Place On The Maine Coast, Andrea Jane Ednie
Sharing A Landscape: The Construction Of Sense Of Place On The Maine Coast, Andrea Jane Ednie
Electronic Theses and Dissertations
Motivated by interest and concern over the changing coastline in Maine, this study uses the concept of sense of place to develop an understanding of how a range of users share the resource, and to explore how place meanings are associated with their social experiences and perceptions. The site for this study was the Stonington region archipelago, an area that has not yet experienced the same amount of development as seen on the southern Maine coast, yet one that has witnessed a boom in recreational use and an influx of people from other areas. Using a mixed methodology, two groups …
Combining Geospatial And Temporal Ontologies, Kripa Joshi
Combining Geospatial And Temporal Ontologies, Kripa Joshi
Electronic Theses and Dissertations
Publicly available ontologies are growing in number at present. These ontologies describe entities in a domain and the relations among these entities. This thesis describes a method to automatically combine a pair of orthogonal ontologies using cross products. A geospatial ontology and a temporal ontology are combined in this work. Computing the cross product of the geospatial and the temporal ontologies gives a complete set of pairwise combination of terms from the two ontologies. This method offers researchers the benefit of using ontologies that are already existing and available rather than building new ontologies for areas outside their scope of …
Advances In Fire Debris Analysis, Mary Williams
Advances In Fire Debris Analysis, Mary Williams
Electronic Theses and Dissertations
Fire incidents are a major contributor to the number of deaths and property losses within the United States each year. Fire investigations determine the cause of the fire resulting in an assignment of responsibility. Current methods of fire debris analysis are reviewed including the preservation, extraction, detection and characterization of ignitable liquids from fire debris. Leak rates were calculated for the three most common types of fire debris evidence containers. The consequences of leaking containers on the recovery and characterization of ignitable liquids were demonstrated. The interactions of hydrocarbons with activated carbon during the extraction of ignitable liquids from the …
Analysis Of Mitochondrial Dna Coding Region Snps By Pyrosequencing, Kyle Robert Carl Parker
Analysis Of Mitochondrial Dna Coding Region Snps By Pyrosequencing, Kyle Robert Carl Parker
Electronic Theses and Dissertations
To date, the use of mitochondrial DNA in forensic analysis has relied on the presence of variations in the control region to differentiate between samples. One problem that this analysis has shown is the occurrence of common Haplogroup H haplotypes or identical sequences. Thus, there is a need to enhance the distinguishing power of this type of analysis. One option has been to investigate the mitochondrial coding region for polymorphisms that could differentiate between samples with identical control region haplotypes. The goal of this study has been to identify polymorphic coding region sites for development in a Pyrosequencing assay that …
Forensic Analysis Of C-4 And Commercial Blasting Agents For Possible Discrimination, Katie Steele
Forensic Analysis Of C-4 And Commercial Blasting Agents For Possible Discrimination, Katie Steele
Electronic Theses and Dissertations
The criminal use of explosives has increased in recent years. Political instability and the wide spread access to the internet, filled with "homemade recipes," are two conjectures for the increase. C-4 is a plastic bonded explosive (PBX) comprised of 91% of the high explosive RDX, 1.6% processing oils, 5.3% plasticizer, and 2.1% polyisobutylene (PIB). C-4 is most commonly used for military purposes, but also has found use in commercial industry as well. Current methods for the forensic analysis of C-4 are limited to identification of the explosive; however, recent publications have suggested the plausibility of discrimination between C-4 samples based …
Maya Eclipses: Modern Data, The Triple Tritos And The Double Tzolkin, William Earl Beck
Maya Eclipses: Modern Data, The Triple Tritos And The Double Tzolkin, William Earl Beck
Electronic Theses and Dissertations
The Eclipse Table, on pages 51-58, of the Dresden Codex has long fascinated Maya scholars. Researchers use the mean-value method of 173.3 days to determine nodal passage that is the place where eclipses can occur. These studies rely on Oppolzer's Eclipse Canon and Schram's Moon Phase Tables to verify eclipse occurrences. The newer canons of Jean Meeus and Bao-Lin Liu use decimal accuracy. What would be the effect of modern astronomical data on the previous studies and the Maya Eclipse Table? The study utilizes a general view of eclipses that includes eclipses not visible to the Maya. Lunar eclipses are …
