Show moreIn this thesis, an e cient approach for topology optimization of three-dimensional (3D) problems has been proposed where the density representation is based on B-splines. Compared with the usual density representation and ltering in topology optimization, the new B-spline based approach is advantageous in both memory usage and CPU time. This is achieved through the use of tensor product representation of density distribution. As such, the storage of ltered density variables is linear with respect to the e ective lter size instead of the cubic order in the usual density lter. Numerical examples of 3D topology optimization of minimal compliance and heat conduction problems are demonstrated. We also show that our B-spline based density representation is especially bene cial to topology optimization methods such as the multiple density per element scheme where the storage of ltered density variables is a challenge. We show that the B-spline approach is also applicable to the multi-resolution scheme.

Show moreElectrochemical energy conversion and storage systems are set to play a major role in the scheme of providing clean and renewable energy to the growing energy demands, both in the nearby and long-term future. PEM fuel cells are the widely tested energy conversion devices with hydrogen as fuel and air as oxidant. Li-ion batteries are commercialized for short and medium range energy demands. But for fulfilling the long range energy demands, research in some new technologies such as Li-air, Magnesium and Sodium batteries are in progress. Magnesium batteries have huge potential to be a high energy density battery suitable for long range electric vehicles and electrical grid energy storage. In PEM fuel cells, Oxygen reduction reaction is the performance limiting factor due to the sluggish reaction kinetics and expensive, but relatively stable Pt catalyst. In the present study, combined DFT modeling and experimental annealing procedure is being employed to improve the ORR activity of Pd by alloying with transition metal elements such as Ni, Cu and Fe. In Li-ion battery, LiFePO4 is the widely commercialized cathode material, but it suffers its limitation of possessing poor electronic conductivity, which affects the cell performance at high discharge rates. A simple isothermal, one-dimensional John Newman Li-ion battery model is being employed to study the effects of changes in LiFePO4, carbon and binder composition towards changes in electrode porosity, electrical conductivity and cell capacity. With the help of modeling results, an optimum composition zone is located for optimizing the high rate performance. In Magnesium batteries, a modified isothermal, one-dimensional John Newman battery model was employed to study the characteristics of the Mg intercalation reactions, predict the performance of the Bi anode electrode and also understand the underlying phenomena and properties that dictate the characteristics of the Mg intercalation in Bi electrode.

Show moreThis study examined perceived social support as moderator between of the relationship between rumination (brooding) and students’ adjustment to university, it also explored rumination (brooding) as a mediator between the relationship of gender and student adjustment to university. Participants included 71 first year undergraduate, graduate, and transfer students. The interaction between perceived social support and brooding was not significant.. Likewise, brooding as a mediator between gender and student adjustment was not significant. Thus, neither the amount of social support students perceived nor whether students were male or female added to the understanding of the relationship between brooding and adjustment to university.

Show moreAssessing impairment in daily functioning is an important part of a mental health evaluation and of monitoring progress in treatment. The Seasonality Assessment Form (SAF; Young, et al., 2014) included a measure to assess the degree of impairment in daily functioning associated with these symptoms. The 5 yes/no impairment items were written to reflect the ways that patients intuitively describe their levels of impairment. However, the items are not mutually exclusive and are not summative so that impairment severity is represented by the configural pattern of responses. This paper examined the nature of response patterns and how to use them to generate an impairment severity score.

Show moreThe purpose of this study was to gain a better understanding of the roles of gender, body mass index (BMI), and rumination in the relation of negative affect (NA) and emotional eating (EE). The following associations were proposed: (1) NA is positively associated with EE, (2) rumination both moderates and (3) mediates the association between NA and EE, (4) gender moderates the association between NA and emotional eating, and (5) EE mediates the association between NA and BMI. Participants consisted of average, overweight, and obese, males (n = 140) and females (n = 152) from both community and university settings. Participants completed self-report questionnaires, including the Binge Eating Questionnaire, Positive and Negative Affect Scale, Dutch Eating Behavior Questionnaire, and Ruminative Response Questionnaire. Results agreed with previous findings that NA positively correlated NA was positively associated with EE. Results indicated that rumination moderated the association between NA and EE; however rather than greater rumination strengthening this association, it led to a weaker association between NA and EE. Rumination mediated the association between NA and EE, and EE mediated the association between NA and BMI. Lastly, gender did not moderate the association between NA and EE. Results indicate the importance of rumination in those with a tendency to emotionally eat. They also point to the impact of EE on BMI, and suggest further studies should examine whether an association exists between EE and weight gain. In addition, results indicate similarities between men and women in regard to emotionally eating in response to NA.

Show moreThis thesis is a continuation of a line of research into the application of multidimensional computerized adaptive testing (MCAT) to the measurement of personality. Using archival data from the 16PF Fifth Edition, a multidimensional item response model (MIRT) was approximated allowing for nonzero item cross-loadings in order to utilize MCAT methodology, which leverages collateral information to administer items more efficiently than unidimensional CAT. Trait estimates obtained from 500 simulated MCAT administrations using actual response data were correlated with traditional CTT trait scores. Results suggest that reductions in test length of up to 50% provide estimates of personality that correlate strongly (from .70 to .86) with conventionally scored results of a full form. Previous research, possible explanations, and implications for item exposure are discussed.
