Advanced Clustering Methods and Applications for Data Visualization

Wu, Bo (2018-04-13)

Categorizing all sorts of data without any label information is one of the most important tasks in preprocessing raw data. To achieve that, an unsupervised learning technique, called clustering, is utilized. Generally, ...

Application of MEMS Inertial Sensors in Sensing Passive Eye Response as a Surrogate for Brain Response to Head Acceleration and Rotation for On-field Objective Assessment of Concussion

Meng, Yuan (2018-11-27)

The passive eye response (PER) may act as a surrogate for the brain response to head acceleration during a concussion causing impact. A novel eye movement sensor designed in this dissertation is used to verify this hypothesis ...

Automated microfluidic device development for metabolism, nutrient uptake, and hormone secretion analyses of primary endocrine tissues

Li, Xiangpeng (2017-07-25)

Pancreatic islets secret the dominant endocrine hormone, insulin, which controls the metabolic function fo nearly all other organ systems. Additionally, adipose tissue (fat) is now understood to be a complex, multicellular ...
