The Effects Of Diet, Size, And Phylogeny On Primate Dental Proportions, Rudolph J. Wilkins
The Effects Of Diet, Size, And Phylogeny On Primate Dental Proportions, Rudolph J. Wilkins
Graduate Theses and Dissertations
It is generally appreciated that there is a relationship between the relative size of the incisors, mandible length, and diet in primates. More specifically, the differences in relative incisor size among primate species are believed to be evolutionary adaptations to their use during food processing and acquisition. While this satisfactorily explains relatively large incisors, it fails to address the relatively small incisor size seen in many taxa. One hypothesis is that there is a trade-off between molar size and incisor size in species with relatively short mandibles. The following study uses two-way ANOVA to evaluate the possibility that spatial constraint …

Capabilities Of Sintered Silver As A High Temperature Packaging Material, Bakhtiyar Mohammad Nafis
Graduate Theses and Dissertations
With electrification progressing across many sectors including industry, automotive and aerospace, the power density requirements are changing. The increased power density results in higher and higher ambient temperatures that electronics are exposed to. The response has been to move towards wide bandgap (WBG) semiconductor devices that can withstand much greater temperatures and can operate at much higher voltages than silicon. Additionally, these WBG devices deliver low drain-source on resistance (RDS_on) capabilities, enabling high current power modules that increase power density even further. This also requires the packaging to evolve in order to withstand the new requirements. As a result, researchers …

Development Of A Prototype Satellite-Tracking Telescope For Ground-Based Spectroscopy, Charles Smith
Development Of A Prototype Satellite-Tracking Telescope For Ground-Based Spectroscopy, Charles Smith
Graduate Theses and Dissertations
Spectroscopy is the practice of determining the chemical composition of a gas through analyzing the light that is filtered by the gas. Spectroscopy is commonly used by astronomers to deduce the atmospheric composition of planets. This process is done by initially measuring the spectrum of light from the star that the planet orbits, and then measuring it again once the planet is in between the observer and the star. The spectrum light that is filtered out is dependent on the chemical composition of the gas, and so this information can be used to determine the chemical composition of the atmosphere …

Deep Learning Frameworks For Accelerated Magnetic Resonance Image Reconstruction Without Ground Truths, Ibsa Kumara Jalata
Deep Learning Frameworks For Accelerated Magnetic Resonance Image Reconstruction Without Ground Truths, Ibsa Kumara Jalata
Graduate Theses and Dissertations
Magnetic Resonance Imaging (MRI) is typically a slow process because of its sequential data acquisition. To speed up this process, MR acquisition is often accelerated by undersampling k-space signals and solving an ill-posed problem through a constrained optimization process. Image reconstruction from under-sampled data is posed as an inverse problem in traditional model-based learning paradigms. While traditional methods use image priors as constraints, modern deep learning methods use supervised learning with ground truth images to learn image features and priors. However, in some cases, ground truth images are not available, making supervised learning impractical. Recent data-centric learning frameworks such as …
