Structural and physical investigations of novel germanium compounds: Aryloxides, nanomaterials, and photolysis of oligogermanes
(2014-05)
The work described in this dissertation will explore the synthesis and characterization of novel germanium containing compounds in order to gain a better understanding of the organometallic chemistry of germanium. These ...
Role of cosmic rays in lightning initiation
(2014-07)
From electric field measurements, the maximum electric fields typically found within a thunderstorm are an order of magnitude too weak to initiate a lightning discharge. Relativistic electrons produced in galactic cosmic ...
Parenting Styles and Dimensions Questionnaire: a Reconceptualization and Validation
(Oklahoma State University, 2014-07-01)
The purpose of this study was to reconceptualize scales of the Parenting Styles and Dimensions Questionnaire (PSDQ) as a typology based on the parenting styles conceptual framework, so that all four parenting styles could ...
Structure-function relationships in the photoactive yellow protein family of photoreceptors
(2014-12)
The amino acid sequence of a protein determines its three-dimensional structure, which in turn determines its functional properties. An intensively studied but still partially unresolved question is how the structure of a ...
New approaches and a subjective database for video quality assessment
(2014-07)
Video quality assessment plays an important role in multimedia systems that process digital images/videos such as video codec, video streaming server. The use of video quality assessment algorithm helps optimize system ...
Using Primitive Pythagorean Triples and the Blom's Scheme in the 4-way Handshake Wireless Security Protocol
(Oklahoma State University, 2014-05-01)
The current standards for wireless security are WPA and its revised version WPA2 (IEEE 802.11i). At the basis of both of these is the WEP protocol that has been broken and automated software can crack it in under a minute. ...
Investigation into the validity of the quantity discrimination curriculum-based measure of early numeracy
(2014-05)
Children come to school with a number of informal math skills (Gersten et. al., 2005; National Mathematics Advisory Panel, 2008). These informal skills include counting, ability to identify numbers, ability to formulate ...
Role of Residual Stresses on Mechanical Properties of Obsidian: Naturally Occurring Glass
(Oklahoma State University, 2014-07-01)
Obsidian is a natural glass that is formed by the rapid cooling of viscous lava. Obsidian's mechanical properties in structure mechanics are visible in aspects such as fracture pattern, elastic modulus, hardness and fracture ...
Evaluation of Epa Levels I, Ii, and Iii Assessments and the Effects of Land Use on Wetland Communities
(Oklahoma State University, 2014-07-01)
Effective tools are needed to monitor and assess wetland ecosystems. The U.S. Environmental Protection Agency (EPA) proposed a three level framework that includes landscape assessments (Level I), rapid assessments (Level ...
