Topological Equivalence And Similarity In Multi-Representation Geographic Databases, Joao Argemiro De Carvalho Paiva
Topological Equivalence And Similarity In Multi-Representation Geographic Databases, Joao Argemiro De Carvalho Paiva
Electronic Theses and Dissertations
Geographic databases contain collections of spatial data representing the variety of views for the real world at a specific time. Depending on the resolution or scale of the spatial data, spatial objects may have different spatial dimensions, and they may be represented by point, linear, or polygonal features, or combination of them. The diversity of data that are collected over the same area, often from different sources, imposes a question of how to integrate and to keep them consistent in order to provide correct answers for spatial queries. This thesis is concerned with the development of a tool to check …
An Implementation Of The El Gamal Elliptic Curve Cryptosystem Over A Finite Field Of Characteristic P, Samuel Thomas Arslanian
An Implementation Of The El Gamal Elliptic Curve Cryptosystem Over A Finite Field Of Characteristic P, Samuel Thomas Arslanian
Electronic Theses and Dissertations
Since the earliest times, individuals and groups of individuals have been interested in communicating sensitive information in a manner which would guarantee that such information could not be arbitrarily received. Further, such information was to be received by select recipients and this required that a means of secure information transmission be found and employed. To these ends, methods of information encryption have ever since been sought and employed. The entire study and practice of this activity, cryptology, the science of message encryption and decryption, provides a framework for this thesis. In particular, the development of cryptology has been influenced by …
Teen Pregnancy: What Brings Teens To Family Planning Clinics For Pregnancy Tests, Norma Reynolds Allen
Teen Pregnancy: What Brings Teens To Family Planning Clinics For Pregnancy Tests, Norma Reynolds Allen
Electronic Theses and Dissertations
The purpose of this study was to explore the factors that bring teenage girls to family planning clinics for pregnancy tests. This study focused on those teens requesting pregnancy tests to investigate the circumstances surrounding their concern that they may be pregnant. A total of 116 teenage girls, between the ages of 13 and 19 completed the 21 item questionnaire. While the results of this study did support previous research showing that teens are using birth control, results found correct and consistent use to be a problem. While most teenage girls reported that they use condoms (73%), over half did …
Wetpreg Reinforcement Of Glulam Beams, Andrew R. Jordan
Wetpreg Reinforcement Of Glulam Beams, Andrew R. Jordan
Electronic Theses and Dissertations
Glued-laminated timber (glulam) is an engineered wood product made by adhering dimension lumber together to form a larger structural member. By combining fiber reinforced polymer (FRP) technology with glulam, it is possible to dramatically increase glulam strength and stiffness, to negate the need for high quality tension laminations, to reduce beam size, to decrease strength variability, to increase ductility, and possibly to reduce glulam cost. A "wetpregn process was used to form the FRP, by impregnating E-glass fabric with a phenolic resin. Following impregnation, the wetpreg FRP was applied to glulam made from eastern hemlock timber. Strength and durability were …
