Mathematical Modeling And Analytical Solutions Of Dissolved Oxygen And Biochemical Oxygen Demand Profiles Under Three-Dimensional, Unsteady-State Conditions, Uing Woong Kim
Dissertations
Mathematical models describing the temporal and spatial distribution of Dissolved Oxygen (DO) and Biochemical Oxygen Demand (BOD) for both pervious and impervious channel conditions in 3-dimensions have been constructed, and their analytical solutions were obtained. The solutions were implemented through the application of a digital computer, and their results are presented.
It has been found that there are significant differences in terms of DO and BOD distribution with respect to time and space in relatively deep and wide channels, thus necessitating the use of a 3-D, unsteady-state model.
Usage And Limitations Of Characteristic Vector Analysis Of Remote Sensing Multispectral Data For The Identification And Quantification Of Water Quality Parameters, Theodore A. Talay
Usage And Limitations Of Characteristic Vector Analysis Of Remote Sensing Multispectral Data For The Identification And Quantification Of Water Quality Parameters, Theodore A. Talay
Civil & Environmental Engineering Theses & Dissertations
Recent applications of the technique of characteristic vector analysis to remote-sensing water color data has met with varying degrees of success. It is apparent from these experiments that a more thorough understanding of the informational capability of characteristic vector analysis is needed.
Probable Causes Of Cracking In A Series Of Reinforced Concrete Box Girder Bridges, Steven Milton Bjordahl
Probable Causes Of Cracking In A Series Of Reinforced Concrete Box Girder Bridges, Steven Milton Bjordahl
Electronic Theses and Dissertations
This thesis is the result of a study undertaken at the request of the South Dakota Department of Transportation (SDDOT) to determine the probable cause of a specific type of cracking that was observed in a series of reinforced concrete box girder bridges. The cracking consists of horizontal cracks through the end diaphragms of the girder and horizontal cracking over the interior bents. Typical crack patterns obtained from information supplied by the SDDOT are shown in Figure 1.
Load And Resistance Factor Design Of Cold-Formed Steel Structural Members, Boonsong Supornsilaphachai
Load And Resistance Factor Design Of Cold-Formed Steel Structural Members, Boonsong Supornsilaphachai
Doctoral Dissertations
"In a traditional design, the Allowable Stress method has long been used for the design of cold-formed steel structures. In this design approach, the allowable stress is always used to prevent the possible structural failure by using an appropriate factor of safety selected primarily on the basis of engineering judgment and long-time experience.
Recently, the concepts of risk and reliability analysis have been successfully applied to many fields of engineering. By applying the theories of probability and statistics, the load and resistance design criteria for steel structures have been developed for the design of hot-rolled steel shapes and built-up members. …

Transverse Thermal Response Of A Composite Bridge, Michael J. Filla
Transverse Thermal Response Of A Composite Bridge, Michael J. Filla
Masters Theses
"A two-span, composite-design, test structure was subjected to thermal loading. The resultant longitudinal and transverse response was correlated with that calculated by a prior theoretical procedure. The theoretical procedure was reconfirmed for longitudinal stress, and indicated within reasonable probability for transverse stress. No measurable diaphragm influence was observed"--Abstract, page iii.
