Investigation of Computational Problem Area Detection on Earthen Spillways Across Varying Image Resolutions
(Oklahoma State University, 2010-07-01)
This thesis work investigates the ability of segmentation algorithms to segment vegetal problem areas in aerial images of earthen spillways. Four different segmentation algorithms were applied to aerial images of spillways ...
Development of Liquid Chromatography-tandem Mass Spectrometry (Lc-ms/Ms) Methods for Exploration of Currency Contamination with Controlled Substances
(Oklahoma State University, 2010-07-01)
The purpose of this research was to develop and validate a method for the quantitation of controlled substances on currency using liquid chromatography with tandem mass spectrometry (LC-MS/MS). The LC-MS/MS instrument was ...
Design of a High Gravity Distillation Unit for On-farm Ethanol Dewatering
(Oklahoma State University, 2010-12-01)
High gravity (Higee) distillation refers to separation of components in a rotating packed bed type contacting device. Rotating packed beds utilize centrifugal force to create artificial gravity up to 200 times greater in ...
Disaster Mitigation Programs in Tulsa, Oklahoma: An Examination of Organizational Survival
(Oklahoma State University, 2010-07-01)
This study uses qualitative analysis to examine how Tulsa Project Impact, a formalized emergent citizen group, survived a major external environmental change. Tulsa Project Impact was formed from FEMA Project Impact, a ...
Practical Application of Hydraulic Tools in Urban Stormwater Design
(Oklahoma State University, 2010-07-01)
The purpose of this study was to identify appropriate hydraulic modeling technologies to aid in the design of urban stormwater systems for small and medium sized communities. The unnamed channel used in this research is ...
Comparison of Electrical Penetration Graph Waveforms of Squash Bug Feeding on Watermelon and Its Relatives
(Oklahoma State University, 2010-07-01)
Cucurbit yellow vine disease is caused by the bacterium Serratia marcescens, which is transmitted by the squash bug, a serious pest of cucurbit. Watermelon is an economically important crop and serves as an alternate host ...
Influence of Post-cooking Holding Time on the Sensory Attributes of Traditional or Suspente(R) Enhanced Flat Iron Steaks
(Oklahoma State University, 2010-12-01)
The objective of the study was to evaluate the influence of post-cooking holding time on sensory attributes of flat iron steaks injected with one of two different enhancements or a control. Treatments consisted of a control ...
Proposed Unified Visual Programming Language
(Oklahoma State University, 2010-12-01)
Throughout time, computer scientists have edited their programs by keypunching, then typing and more recently by typing and `point-and-clicking'. The need for improving the editing of a computer program is driven mainly ...
Investigation on the Aerodynamic Performance of a Vertical Axis Wind Turbine
(Oklahoma State University, 2010-12-01)
The two dimensional unsteady flow around a vertical axis wind turbine (VAWT) comprising three rotating symmetric airfoils (NACA0018) was studied numerically with the consideration of the near wake. The simulations were set ...
Modeling of Turbulent Particulate Flow in the Recirculation Zone Downstream of a Backward Facing Step Preceding a Porous Medium
(Oklahoma State University, 2010-12-01)
The current study focuses on flow characteristics and particle motion in the recirculation zone downstream of a backward facing step preceding a porous medium. A two dimensional backward facing step is created in ICEM CFD ...
