Impact Of Camera And Lighting Position On Video Detection Precision, Avery Rhodes, Kristofer Jennings, Darcy M. Bullock

JTRP Technical Reports

On well-illuminated approaches, vehicle headlight reflections on the pavement were observed to cause video detection units to activate early. This early activation results in a dramatic increase in the length of the effective vehicle detection zone. This observed variation in the effective length of the vehicle detection zone that varies by ambient lighting condition and camera placement presents a very serious impediment for traffic engineers to design vehicle extension intervals that operate correctly during day, night and transition periods. Furthermore, the stochastic variation in the length of the vehicle detection zone length has the potential to create driver expectancy issues. …

Landscapes Of Imagination: A Critical Analysis Of Art Textbooks, Lynda C. Kerr

College of Graduate Studies: Theses & Dissertations

Author's abstract: This qualitative study examined imagination in secondary art textbooks, both historically and in the current educational climate. An arts-based inquiry, as described by Barone & Eisner (Jaeger, 1988), investigated how imagination is manifested in some art books, how the standards movement has tended to limit imagination in art textbooks, and how art textbooks could expand students' imaginations. Using a framework based on the theories of Dewey (1934/1980), Greene (2001), and Eisner (2002), four art textbooks were analyzed for their qualities which expand students' imaginations. The study described a design for an imaginative art textbook. Analysis focused on the …

Thermal Stress In Concrete Slabs Under Different Constraints, Dhananjay Rao Hejamadi

Graduate Theses, Dissertations, and Problem Reports (ETD)

Previous research has shown that thermal stresses developed in concrete pavements due to daily and seasonal temperature variations may be larger than those induced due to traffic loading. Dowel bars that are used for load transfer at the transverse joints of concrete pavements introduce high stresses at their interfaces with concrete leading to various forms of transverse joint distress. To solve this problem, Shoukry et al. (2001) developed an alternative design of dowel bars called "Shok Bar" that was installed by Shoukry and his team in a concrete pavement section placed at the parking lot of WVDOT Maintenance Shop at …
