A Socio-Economic Traffic Demand Prediction Model Based On A Lumped System Approach, John Edward Thompson
A Socio-Economic Traffic Demand Prediction Model Based On A Lumped System Approach, John Edward Thompson
Masters Theses
"The objective of this investigation was to devise a method for predicting transportation system demand based on socio-economic variables of certain physical areas. This pilot study was performed utilizing traffic flow, but minor mathematical alterations could change the transportation system to urban mass transit usage demand. An area of uniform socio-economic characteristics can be delineated and the socio-economic characteristics isolated. Each area will place a distinct demand on some existing transportation facility based on those characteristics. The physical demand can be approximated by a theoretical probability distribution. Once this internal flow generation has been approximated by the frequency distribution, it …

Multi-Stage Shear Testing Of A Cohesionless Soil, Robert Clyde Gullic
Multi-Stage Shear Testing Of A Cohesionless Soil, Robert Clyde Gullic
Masters Theses
"The multi-stage test is a procedure by which a soil's shear strength parameters can be evaluated by the use of a single sample of the material. The object of the investigation is to evaluate to what extent multi-stage testing can be used on a cohesionless material. Three types of tests, using conventional and multi-stage procedures are evaluated. They are: direct shear/consolidated drained, triaxial compression/consolidated drained and triaxial compression/consolidated undrained shear tests. It was found that multi-stage testing can easily be performed and the shear strength parameter thetaf obtained from these tests are in good agreement with those obtained from …

A Proposed Concept For The Rapid Field Design Of Protective Structures, John Ross Childress
A Proposed Concept For The Rapid Field Design Of Protective Structures, John Ross Childress
Masters Theses
"This investigation proposes a simplified concept for the rapid field design of protective structures, subject to attack by conventional artillery rounds, mortar rounds and small rockets. Parameters which should be considered during a rigorous design process are discussed. The number and complexity of these parameters make the rigorous design procedure too unwieldy to be efficiently used, in a limited time period, when materials are not available to comply with Standard Designs. Since the duration of an explosion pulse is very short and uncompacted soil is capable of absorbing explosive energy, this study investigates the theory that adequate protection can be …
