Applications of Unsupervised Clustering in Functional Magnetic Resonance Imaging

Zhao, Xinyu (2016-12-12)

Functional Magnetic resonance imaging (fMRI) is a noninvasive neuroimaging technique that measures brain activity by detecting changes associated with blood flow. This technique has been widely used in radiology, biomedical ...

Efficacy of Price Interventions for Mitigating Childhood Obesity by Promoting Healthy Food Choices: An fMRI Study in Parents with Low Socioeconomic Status

Zou, Hao (2016-12-07)

Childhood obesity has been a rising problem among rural and low income populations. Childhood obesity increases the risk of various diseases later in life. Government has tried several price interventions such as lowering ...

An Experimental Investigation of the Neural Correlates of the Acquired Capability for Suicide

Willis, John (2017-07-27)

The high rate of fatal suicide attempts in men is a pressing issue as highlighted in the public conscious. The interpersonal–psychological theory of suicide has offered an explanation for the difference in suicidal behavior ...

Fluctuating Asymmetry of White-Tailed Deer Antlers

deFreese, Rachel (2007-08-15)

Fluctuating asymmetry has been proposed as an indirect indicator of individual quality. Sexually selected traits, such as deer antlers, are expected to exhibit patterns of decreasing level of fluctuating asymmetry with ...

High Quality CT Image Reconstruction from Limited Projections Obtained from MiSpinner

Zhou, Huanyi (2016-05-05)

Computed tomography (CT) technology is widely used in the medical and industrial fields. However, a traditional CT machine costs too much for many researchers to afford it and prevents them from doing related research. To ...

Improving Sonar Reconstruction with Sparse Reconstruction Techniques

Lindmark, Brian (2016-12-09)

In many sonar applications, traditional processing can fail to provide adequate information to accomplish the respective goals, because the processed information is either strictly bandlimited to the transmit band, distorted ...

Interpretable Deep Learning for Diagnosis of Human Brain Disorders using Neuroimaging

Masood, Janzaib (2020-11-17)

Deep neural networks are increasingly being used in neuroimaging research for the diagnosis of brain disorders and understanding of human brain. They are complex data driven systems that work in a black-box fashion once ...

Investigating Brain Function using Functional MRI-based Meta-analysis and Diffusion Tensor Imaging

Baxi, Madhura (2015-05-04)

The investigation of structure and function in biological systems, specifically the brain, is paramount given the close relationship that they share with each other. Functional magnetic resonance imaging (fMRI) and Diffusion ...

Kalman Filter Based Tracking Algorithms For Software GPS Receivers

Lashley, Matthew (2006-12-15)

In this thesis several new Kalman filter based tracking algorithms for GPS software receivers are presented. Traditional receivers use Costas loops and Delay Lock Loops (DLL) to track the carrier and Pseudo-Random Noise ...

Layer-Specific Connectivity Analysis with High-Resolution Functional MRI in Human Brain

Wang, Yun (2016-12-09)

Functional magnetic resonance imaging (fMRI) has been increasingly used for understanding the human brain connectome. In this work, we utilized high-resolution fMRI to investigate the sensitivity of layer-specific connectivity ...

Motion Estimation from Tagged MR Images and Application to Cardiac Strain Evaluation and Functional Analysis of Ocular Tissues

Li, Ming (2015-09-23)

Tagged MRI is a magnetic resonance imaging technique that has been widely applied to tissue functional evaluation, especially the myocardium. Unlike traditional anatomical imaging methods, tagged MRI spatially encodes the ...

Noninvasive hepatic lipid quantification with magnetic resonance imaging and spectroscopy

Khan, Salaar (2019-04-18)

Excessive accumulation of intra-hepatocellular lipid (IHCL) can lead to one of the most common forms of chronic liver diseases in adults, the non-alcoholic fatty liver disease (NAFLD), that comprises a range of liver ...
