This paper documents the development of a model which determines multiple stump anchor system displacement as a response to skyline load for four anchor rigging configurations: 1. Series multiple, 2. Tieback, 3. Elevated tieback, and 4. Equalizer block. It also documents the field testing of four two stump anchors rigged...
With rising fuel costs and enhanced environmental concerns, the use of renewable energy has been steadily considered and widely expounded as a solution to the challenges of global energy security and climate change. The use of woody biomass, in particular, has received considerable attention for energy production due to the...
Augered cast-in-place piles, also known as ACIP piles, have been used for more than
seven decades in the United States and have gained in popularity due to their relatively
quick installation and cost-effectiveness. Owing to the reduced impact on the neighboring
environment as compared to some other deep foundation installation...
Woody biomass transportation costs and market values/costs are strongly correlated with the woody biomass moisture content. Properly managing moisture content can potentially lead to economic and environmental advantages in biomass energy markets. Good management requires accurate moisture content measurements. Therefore, availability of accurate, precise, reliable, and efficient tools to assess...
This research addresses fleet-sizing for reusable containers that are used for
protection, transportation, and storage of parts between a component plant and
assembly plant. These reusable containers are often expensive and occupy a
large amount of storage space when empty and full. Having a large container
fleet comes with higher...
Gap acceptance behavior is critical to the safety and operational performance of unsignalized intersections. The complex nature of the human behavior and its dependence on various socioeconomic and environmental parameters makes it challenging for transportation professionals to assess the performance of such intersections. To investigate the behavioral patterns of drivers...
Mechanical design is often based on formal methodologies such as Quality Function Deployment. Techniques to quantitatively account for attractability, sensory perception, and affective design have been successfully incorporated into these methods and are receiving growing acceptance across many industries. Although the adoption of these methods marks a large improvement for...
This dissertation consists of two essays that address code-sharing alliances in the U.S. domestic airline industry.
The first essay examines the economic impact of code-sharing using data from the complementary code-sharing agreement between Southwest and ATA Airlines. This code-share agreement is found to decrease air fares and increase passenger volumes...
A computer program called SAPWOOD which possesses the
capability of performing linear or nonlinear, static or
dynamic response including seismic excitation for wood-framed
buildings with semirigid connection systems is
presented in this study. Program SAPWOOD is a modification
of the program NONSAP by adding new elements such as a
linkage...
