Electronic Data Collection For Rockfall Hazard Evaluation, Derrick Ladon Bellamy

Masters Theses

Rockfall field data collection traditionally has used conventional stationery tools, i.e. pencil and paper, for data collection. Traditional methodologies are being revisited with the advent of PDA’s (Personal Digital Assistants) or penbased computers. With the utilization of such technology, field data can be collected electronically. An electronic data collection system using PDA’s was developed for this thesis. The advantages of the PDA approach over pencil and paper data collection include automatic error and data integrity checks during data input, and the elimination of manual data entry. The PDA’s also allow automatic branching to solicit data input based on previous data …

Interface Behavior Of Water Saturated Limestone Rock Joints Using Hollow Cylinder Testing And A Case History Regarding Mine Roof Stability: Fort Hartford Mine Superfund Site, Roger W. Cecil

Masters Theses

Presented herein is a multi-part thesis prepared to partially meet the requirements for the Master of Science degree in Civil Engineering at the University of Tennessee. Part I provides a brief introduction to the two primary thesis topics that are presented in Parts II and III, respectively.

Part II presents findings from a series of tests performed with a hollow cylinder combined axial-torsional testing apparatus to study the effects of confining fluid pressure on the shear strength of artificial rock joints for Holston Limestone. Tests were performed for confining fluid pressures of 0.14 MPa to 0.55 MPa and effective joint …

Development Of A Model To Assess The Effect Of Ozone On Public Health Using Models-3/Cmaq, Pedro Alex Sanhueza H.

Doctoral Dissertations

According to the Clean Air Act, the establishment of priorities in air pollution control should be based on benefits to public health and welfare. Given this mandate, EPA has incorporated the health effect evaluation in the regulatory impact analysis of its rulemaking, such as Tier2 sulfur gasoline reduction and HDE diesel emission reduction. The Tennessee Department of Environment and Conservation (TDEC) has identified ozone as the primary pollutant of concern. All these antecedents provided the basis for developing a decision-making tool that helps to evaluate the various regulatory options in controlling the emission of ozone precursors from a health-effects point …

An Evaluation Of The Impact Of Lane Use Restrictions For Large Trucks Along I-40 Near Knoxville, Vasin Kiattikomol

Masters Theses

This thesis is concerned with studies on an effectiveness and impact of lane restriction for large trucks from a left lane on Interstate 40 near Knoxville. The data collection was conducted in July to August 2001 and March to April 2002. The restriction was implemented on August 13, 2001. The lane distribution and individual speed of large trucks in each lane were then gathered to obtain patterns and characteristics of large trucks ‘before’ and ‘after’ the implementation. A database was developed, a data comparison was conducted, and a statistical test was applied. The findings reveal several significant changes of lane …
