An Analysis Of The Passenger Vehicle Interface Of Street Transit Systems With Applications To Design Optimization, Walter H. Kraft

Dissertations

This research analyzes the Passenger Vehicle Interface of the street transit systems and presents applications for design optimization. The Passenger Vehicle Interface (PVI) is defined as the interaction between the passenger and vehicle elements of the street transit system.

Human observer and photographic studies were conducted in 17 cities in the United States and Canada to measure the time for queues of passengers to board various transit vehicles. The data were analyzed by considering seven factors that affect the Passenger Vehicle Interface: Human Factor, Modal Factor, Operating Practices, Operating Policies, Mobility, Climate and Weather, and Other System Elements. Those effects …

A Unit Hydrograph For The Missouri Ozark Region., Melvin G. Schaefer

Masters Theses

"Eleven small watersheds from the Missouri Ozark region are used in generating a synthetic unit hydrograph. The analysis is composed of three parts: First, a prediction equation is developed which correlates the time lag parameter with the physical features of the watershed. Second, an equation is developed which predicts the peak flow ordinate for 30-, 60- and 120-minute unit hydrographs. Third, an average dimensionless unit hydrograph is determined"-- Abstract, p. iii

A Study Of Trace Organics And Trace Organic-Bound Metals In Raw And Finished Waters., Robert Lee Stewart

Masters Theses

"The main objectives of this study were: (a) to prepare a comprehensive review and evaluation of the literature pertaining to trace substances, with emphasis on their status in water supplies, health effects, and fate in treatment; ( b) to establish the methodology needed for measuring trace metals in trace organic substances; and (c) to determine the metal content of organic extracts recovered from surface, subsurface, and finished waters.

Raw and finished water was obtained at the Sedalia, MO, water treatment plant, and 5 sources were sampled (3 surface, 1 well, 1 plant-treated). The 0-CA* and SEM procedures were employed to …

Wastewater Treatment With Activated Carbon., Chia-Soui Joseph Lu

Masters Theses

"The objectives of this study was to determine the capabilities of selected types of activated carbon as an adsorbent for the removal of organic materials from municipal wastewater and sludges. The organic sources included primary and secondary clarifier effluent, blended sludge, and digester supernatant. Two other organic sources, glucose and alanine, were also examined to determine their removal from aqueous solution by activated carbon adsorption.

The organic impurities, in terms of chemical oxygen demand (COD), were reduced from 68 mg/1 in the primary effluent and 35 mg/1 in the secondary clarifier effluent to approximately 15 mg/1 for both. However, the …

Ultrasonic Instrumentation And The Dynamic Evaluation Of Asphalt-Aggregate Mixtures., John Edward Hill

Masters Theses

"Ultrasonic probes have been constructed for use in the dynamic and nondestructive testing of asphaltic concrete specimens. The probe systems exhibited characteristics superior to the solitary ii use of their main components, the piezoelectric crystals. The probes have the advantages of the reduction of ringing time, the concentration of ultrasound in one direction, the elimination of "noise" due to unshielded connections and the increased durability of the probe system.

The probes constructed were used in a limited testing program. Compression and transverse wave velocities in the specimens tested were measured simultaneously. Sample conditions suitable for maximum wave velocity corresponded to …

Disposal Of Lead And Zinc Cationic Wastes On Soils., Stephen Melvin Linnemann

Masters Theses

"The sorption and desorption of lead and zinc on soil samples from the "New Lead Belt" of southeastern Missouri and from Springfield, Missouri, were investigated using both column and batch systems. These cations were selected for study because of the possible effects which soil pollution in the "New Lead Belt" mining region could have on shallow aquifers and because both metals are utilized in the electroplating industry.

It was found that soil has the ability to sorb lead and zinc; however, the cation-exchange capacity (C.E.C.) of the soils studied was not fully satisfied, though there was evidence that i f …

A Method Of Predicting The Economic Effects Of Highways In Undeveloped Countries., Mohamed Magzoub Abdallah

Masters Theses

"This paper reviews the findings of the socio-economic impact studies pertaining to land-use changes. An attempt is made to explain, through land-use studies, the relationship between the past and future development of the City of Rolla, Missouri, and the system of highways serving the city, The relationship between land-use changes, expressed in active units rather than areas, and the level of activity related to those changes, rep resented by 0-D traffic volumes, is studied for Rolla and the difference in the behavior of this relationship in undeveloped countries is discussed"-- Abstract, p. ii

Dynamic Testing Of Anchors Buried In Dry Sand., Jim Lee Hillhouse

Masters Theses

"The dynamic pullout resistance of anchors was investigated through the use of model testing under controlled conditions. The soil used for the model tests was a dry sand compacted to a uniform relative density of approximately 92 percent. The dynamic loading of the anchor-soil system was applied by a mechanical device, which applied a specific amplitude and frequency of dynamic load to the anchor-soil system.

The dynamic testing of the anchors consisted of two phases. First, an initial static load was applied to the anchor. Second, a dynamic load was superimposed over the initial static load. The load applied to …

A Study Of Trace Organic Emissions In Mining And Milling Wastewaters In The New Lead Belt Of Southeastern Missouri., Alan James Callier

Masters Theses

"The primary objective of this study was to evaluate the trace organic contributions by two lead and zinc mining and milling operations in Southeastern Missouri. A secondary objective was to evaluate a reverse osmosis-solvent extraction method for use in recovering trace organics.

Trace organics were recovered in the first phase of the study following procedures as outlined by the American Society of Testing and Materials (ASTM), with chloroform and benzene being used as the solvents. The data indicated that the milling waste contained a larger concentration of trace organics than the excess mine water. Furthermore, it was shown that recycling …

Denitrification Of A Synthetic Waste With A Submerged Filter, Dominic Joseph Grana

Masters Theses

"The facultative anaerobic submerged filter is a plug flow, packed bed, column type reactor in which the facultative microorganisms responsible for nitrate reduction are attached to the filter media. The objective of this study was to evaluate filter performance and the kinetic equations of the process under variable conditions of flow rate, nitrate nitrogen concentration, and organic loading.

Two 0.5 cu ft (14.25 1) laboratory filters were operated for 144 days at 35°C using a synthetic waste as the substrate. Filter media consisted of smooth quartzite stone, 1 to 1.5 in. (2.54-3.82 cm) in diameter. Each filter had a porosity …
