Gal: A Stepwise Model For Automated Cloud Shadow Detection In Hico Oceanic Imagery Utilizing Guided Filter, Pixel Assignment, And Geometric Linking, Jennerpher Renee Meyers

Dissertations

Detection of cloud shadow pixels is an important step in image processing in several remote sensing ocean-color application domains, such as obtaining chlorophyll content. While shadow detection algorithms do exist, the vast majority are for over land which leaves few options for detection over water.

The detection of cloud shadow over water in HICO imagery is a unique problem. As its name implies, HICO (Hyperspectral Imager for the Coastal Ocean) imagery is produced for coastal and oceanic regions. Since land based algorithms remove water before processing, these approaches would not be applicable. The only currently published HICO shadow pixel detection …

Personality And Relational Aggression In College Students: The Role Of Social Anxiety And Rejection Sensitivity, Daniel Locke Deason

Master's Theses

Relational aggression involves the intentional infliction of harm via damaging one’s relationships or sense of belonging. Previous research suggests that relational aggression among children and early adolescents is correlated with social ostracism, poor psychological adjustment, anxiety, and depression in victims, and there is increasing evidence that many of these correlates apply to relational aggression among older adolescents and emerging adults. Efforts to identify predictors of relational aggression are underway; however, many variables which have been influential in understanding other forms of aggression have not yet been examined. The Five Factor Model (FFM) of personality is one example, as it has …

Material Coefficient Of Thermal Expansion Investigation For Use In Additive Manufacturing Fused Deposition Modeling For Composite Tooling, Daniel Joseph Miller

Master's Theses

Polymer matrix composites are being used to manufacture light weight, high stiffness aircraft structures. These structures are often manufactured from carbon fiber reinforced epoxy. When these structures are damaged, they must be repaired to restore strength to the component to avoid the cost and logistics of having replacements parts. Occasionally, these repairs require tooling in order to make a quality repair, however, tooling generally has a long lead time. Additive manufacturing could be used to manufacture rapid tooling to create tooling for composite repairs. The issue is that polymer printed tooling has a much higher coefficient of thermal expansion (CTE) …

Furthermore, group contingency interventions, such as the GBG, can be conceptualized as Tier I or Tier II interventions within a …

Humor Types: Replication Using Latent Profile Analysis And Associations With Maladaptive Personality Traits, Joseph Robert Finn

Master's Theses

Martin’s (2003) Humor Styles Questionnaire measures four distinct styles of humor usage. However, examining these humor styles individually fails to account for the combination with which they are used as well as how these combinations may affect the relationship between humor and personality. The present study examined relationships of the humor styles, both individually and in combination, with a broad array of maladaptive personality traits. The incremental validity of accounting for the combinations with which the humor styles are used was examined through the use of hierarchical multiple regressions. Results demonstrated that the humor styles, both individually and in combination, …

Perceived Attributes And Factors Influencing Instructors’ Using E-Textbooks In Higher Education, Sirui Wang

Psappha By Iannis Xenakis: Developing Multiple Percussion Literacy, Owen Phillip Rockwell

Dissertations

Psappha by Iannis Xenakis was written for a solo percussionist in 1975, and since then has been performed almost exclusively by elite musicians. The work suffers from broad neglect by students and professionals alike, because the structure and notation are difficult to access. Through Psappha, Xenakis created an alternative approach to serialist and chance compositional techniques that enabled him to communicate what he believed was rhythm in its purest form. The notation is unconventional and challenges the performer to approach Psappha in a similar manner. The main thrust of this project was to re-imagine the work in a more …
