The Linear New City -- A Pattern For New Cities Based On Efficiency Of Transportation, Public Services, And Land Use, Elbridge Wesley Bartley Iii

Masters Theses

"The linear new city is defined as a city consisting of some arrangement of relatively narrow, high-density strips, served by various mass transportation systems. Such a new city would be ideally suited to the implementation of the latest technology. The concentration of development along the transportation route would allow certain economies in the supply of utilities and services, as well as insuring that open space would be readily available around and throughout the city. The provisions for transportation, housing, and governmental control should combine to produce a better quality of life for the inhabitants of the linear new city"--Abstract, page …

A Highway Rest Area Design Based On A Use Study In Outstate Missouri, Dimitris Peter Perandakos

Masters Theses

"The limited number of rest areas in the State of Missouri does create a major problem for the motorist travelling in this state.

The author became more aware of this problem from personal experience and decided to investigate it. For that he interviewed over one thousand motorists on the only rest area that is located on 1-44, near the city of Stanton. He also took traffic counts to determine the average daily traffic volumes of Highway 1-44 and of the rest area stated above.

The data collected from the above steps was used for the design of a new rest …

The Evaluation Of An Activated Sludge Process At Elevated Temperatures, Peter J. Dawson

Masters Theses

"The feasibility of utilizing the thermal energy from an electric power plant to operate an activated sludge process at elevated temperatures (above 40°C) was assessed.

The practicality of using this heat was determined from a heat transfer analysis and the operation of the activated sludge process was evaluated from laboratory studies of a batch process treating domestic and synthetic sewage.

The tank size for a thermophilic activated sludge chamber could be reduced by 40 to 50% as compared to ambient temperatures. For thermophilic processes a temperature of 55°C is recommended because the transition phase between mesophiles and thermophiles is around …

Chemical And Ultrasonic Conditioning Of Water Treatment Plant Coagulant Sludges, Stanley Louis Klemetson

Masters Theses

"The objective of this investigation was to evaluate the use of ultrasonic energy, pH adjustment, and addition of polyelectrolytes in dewatering coagulant sludges. Emphasis was placed on the effects of the ultrasonic power output level and period of conditioning, the chemical conditioning of the sludge, and the type and origin of the sludge. Dewatering is thought to be the most practical approach for reducing the volume of coagulant sludges and efforts are being made to improve their dewatering characteristics.

An experimental system consisting of a magnetically stirred sludge reservoir, sonifier and reaction chamber, polymer feeder, and collection cylinder was developed …

Attitude Scaling As A Public Involvement Tool In The Lower Mississippi River Region Comprehensive Study, William A. Lee

Masters Theses

"The planner is under considerable pressure to involve the public in water resource planning. The public, however, often lacks sufficient knowledge to offer useful comments or suggestions. The use of a Likert Type Attitude Scale in the public involvement effort of the Lower Mississippi Region Comprehensive Study demonstrates the usefulness of attitude scaling techniques in obtaining public input to the planning process. The measurement of an individual's attitude, or his thoughts, feelings and disposition to act toward some aspect of his environment with some degree of consistency, gives an indication of the goals and objectives toward which a plan acceptable …

Marshall Properties Of Asphaltic Concrete Containing Glass-Rich Fractions, James Joseph Schneider

Masters Theses

"The use of crushed waste glass as an aggregate in asphaltic concrete has been suggested as a means for re-using glass separated from municipal refuse. Laboratory studies and field installations have generally utilized clean glass obtained by hand sorting bottles from the other refuse and crushing them to produce a desired gradation. For this type of asphalt to be economical though, the glass fraction must be separated mechanically. For mechanically separated materials, the glass-rich fraction also contains such items as metal, bone, rubber and other non-glass materials.

The objective of the study was to determine the effects upon Marshall properties …

Driver-Vehicle-Roadway Interaction Model, Mark E. Jaeger

Masters Theses

"A non-trivial simulation model has been developed which combines driver and vehicle dynamics with the roadway into one system. The model was successfully simulated on a portion of an existing roadway with the dynamic response and performance of the simulator being subjectively realistic. By implementing the idea of the interaction of variables, a much more detailed and representative response is obtained as compared to previous models based solely upon a single-factor-effect approach. By analyzing a simulated vehicle's velocity and trajectory, it is felt that an increase in driver "look ahead" distance or a decrease in vehicle velocity tends to improve …

A Comparison Of Three Urban Hydrology Models, Richard F. Astrack

Masters Theses

"Three models, the British Road Research Laboratory Hydrograph Method, the Hydrocomp Simulation Program, and the HEC-1 Flood Hydrograph Package, are applied to the Boneyard Creek basin. Comparing the ability of these models to reproduce the observed peak discharge, time of the peak, and the first runoff volume determines the accuracy of these models"--Abstract, page iii.
