This thesis describes a strategy to predict steady aeroelastic response of an automobile hood at high speeds using coupled fluid dynamic and structural codes. The pursuit of improved fuel economy through weight reduction, reduced manufacturing costs, and improved crash safety can result in increased compliance in automobile structures. However, with compliance comes an increased susceptibility to aerodynamic and vibratory loads. The hood in particular withstands considerable aerodynamic force at highway speeds, creating the potential for significant aeroelastic response that may adversely impact customer satisfaction and perception of vehicle quality. The goal of this thesis is to develop and couple high fidelity fluid and structural computational models to improve the understanding of fluid-structure interactions between automobile hoods and the surrounding internal and external flow. Computational analysis is carried out using coupled CFD-FEM solvers with detailed models of the automobile topology and structural components. The experimental work consists of wind tunnel tests using a full-scale production vehicle. Comparisons between the numerical and experimental results yield important insights into required modeling fidelity, coupling, and challenges in validation for the aeroelastic response of automobile hoods. Three separate vehicle configurations are considered. The first configuration resembles an initial design model or “styling” model which neglects the internal flow through the front fascia and has a simplified underbody and wheels. The second configuration is a “complete” model including all vehicle components. The last configuration is an adaptation of the complete model employing a simplified engine compartment and underbody. One motive for the last configuration is the complete model was found to have inadequate mesh cell quality to implement into the coupled simulation framework, but a model with reduced complexity is satisfactory.

My thesis sought to explore the sizable sub-genre of fairy tale adaptations in contemporary literature with the intent to subvert a series of fairy tale tropes, themes, and motifs that appear both in the original tradition of the tale and in the contemporary retellings. The tradition itself establishes a firm matrilineal relationship across three generations within a singular family, maintains a sexist tone throughout Little Red's cautionary tale, and promotes the idea of a "knight in shining armor" via the Huntsman character. The contemporary retellings in young adult literature choose very similar avenues of translating the iconic components of the original fairy tale into a modern text, but continue to promote its sexist ideals in different ways. I set out to write a novel that adopts the quintessential themes of the Little Red Riding Hood fairy tale, but challenges the sexist undertones which perpetuate in all its adaptations. In the end, I have adapted the tale into a young adult text that highlights the importance of strong female bonds without glorifying the "male savior" trope or reducing the other female characters to mere plot devices.

Carol E. Briney is the founding executive director of Reentry Bridge Network, Inc. and Reentry Solutions, Inc. Briney believes that a systematic approach is required to reduce the likelihood of recidivisim. For nearly a decade, she has written and facilitated holistic pro-social programs inside prisons and in community forums. Her programs support bridging the gap between prison and community by focusing on human value, grief-impairment, daily literacy, reentry and job readiness, trauma-informed care, the healing arts, and understanding poverty. Briney's work is founded on her strong belief - If we can’t help people to realize their own universal value, how can we expect them to see the value in their victims or their environment? This is gained through asset building, not punitive action. It takes community to reduce recidivism.

Scouting for insect pests is the backbone of all Integrated Pest Management (IPM) programs. The success of IPM programs relies on the insect pest population estimates that scouting methods provide. Scouting methods can reduce the number of pesticide applications by 40 to 60% (Hollingsworth et al., 2000) and pesticide use by 30% (Cloyd et al., 2005). However, most of the scouting methods are unreliable, labor demanding and tedious. Therefore, this research effort recognized the need of the greenhouse industry for a system that is capable of covering a large greenhouse growing area while collecting samples consistently and time efficiently. Two greenhouse scouting methods were selected based on collection efficiency, labor requirements and mechanization feasibility. These methods were the vacuum approach and the sticky card. To allow automatic sampling of insects both scouting methods were prototyped and mounted on an overhead automatic irrigation system. The two prototypes were named: 1) the mobile insect vacuum, and 2) the mobile sticky card. To compare the collection efficiencies of the prototyped mobile methods and a traditional yellow sticky card, greenhouse tests were carried out. Tests were conducted to investigate the effects of two greenhouse air temperatures (13.5 and 28.5°C) and the use of an assisting air jet on the collection of adult whiteflies (Bemisia tabaci) from poinsettia (Euphorbia pulcherrima) cv. Freedom Red canopies. Results from these tests showed that the air assisted mobile insect vacuum had the highest mean collection efficiency (MCE= 3.0 ± 0.5 %). The method was capable of consistently collecting adult whiteflies from poinsettia plants at 13.5 and 28.5°C. Improvements in the air assisted mobile insect vacuum prototype collection efficiency were deemed desirable for more reliable insect detection. To aid in the design process of the proposed insect collection system, analytical and numerical models based on turbulent jet theory and computati (open full item for complete abstract)

In “Money and the Man: Economics and Identity in Late Medieval English Literature,” I explore the relationship between the profound economic changes of the late medieval period and shifting models of subjectivity. I argue that often-noted economic transformations, such as the expansion of the money economy, the commercialization of English society, and the general increase in personal wealth, had consequences far beyond the marketplace. Indeed, such changes had a significant impact on how people imagined themselves and others to be defined, causing a shift from societal models of birth and function to paradigms emphasizing economic activity and income. Increasingly, I suggest, being was related to having. Further, I posit that these changes were awkwardly embraced, generating widespread yet local anxieties among various groups, such as the gentry, the religious, and the merchant class. It is the work of this dissertation to explore a group of texts—romances, saint's lives, and ballads—which chronicle the struggle to formulate meaningful identities in a society in flux.

A total of 484 tests were performed on chemical laboratory Hoods (chemical hoods), using the ANSI/AIHA Z9.5-1992 (American National Standard Institute / American Industrial Hygiene Association, Laboratory Ventilation Standard) test method (ANSI-1992). Same numbers of the tests were performed on same chemical hoods, using the ANSI/ASHRAE 110-1995 (American National Standards Institute/American Society of Heating, Refrigerating, and Air Conditioning Engineers, Method of Testing Performance of Laboratory Fume Hoods) test method (ASHRAE 110). The three types of chemical hoods available for this study were Constant Air Volume (CAV), Variable Air Volume (VAV), and Low Flow. Overall, CAV hoods had the highest passing rate for the ASHRAE 110 (83%) followed by VAV hoods (82%) and low flow hoods (68%). The X2 test for homogeneity found a statistically significant difference between the test outcomes (pass/fail) of the ASHRAE 110 and the ANSI-1992 methods (X2 = 4.248, P=0.038) for VAV hoods only. Overall, 18% of the CAV and VAV chemical hoods tested in the 80-120 feet per minute (fpm) average face velocities, failed to meet the ASHRAE 110 test criteria. If the ANSI-1992 test method was performed alone, 18% of the chemical hoods would be certified while they were not able to meet the ASHRAE 110 criteria. Logistic regression analysis for VAV and CAV chemical hoods revealed that for VAV chemical hoods, the ASHRAE = Velocity model and for CAV chemical hoods, the multi variable regression model ASHRAE = ANSI + Velocity were appeared to be the best model for the ASHRAE 110 test outcome prediction.
