Emerging Technologies And Advanced Analyses For Non-Invasive Near-Surface Site Characterization, Aser Abbas
Emerging Technologies And Advanced Analyses For Non-Invasive Near-Surface Site Characterization, Aser Abbas
All Graduate Theses and Dissertations, Fall 2023 to Present
This dissertation introduces novel techniques for estimating the soil small-strain shear modulus (Gmax) and damping ratio (D), crucial for modeling soil behavior in various geotechnical engineering problems. For Gmax estimation, a machine learning approach is proposed, capable of generating two-dimensional (2D) images of the subsurface shear wave velocity, which is directly related to Gmax. The dissertation also presents a method for estimating frequency dependent attenuation coefficients from ambient vibrations collected using 2D arrays of seismic sensors deployed across the ground surface. These attenuation coefficients can then be used in an inversion process …

Flash Lab: A High-Speed Imaging Laboratory, Cody D. Hatch
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
To help students become better acquainted with high-speed instrumentation and measurement techniques, a high-speed imaging laboratory for the College of Engineering is equipped with a high-speed camera and schlieren imaging device. The laboratory will be used for labs in classes, such as Instrumentation, Thermal/Fluids Lab, Experimental Solids, and Mechanical Experiments. In addition, graduate students will use it for research purposes. The laboratory also has the potential to have a course associated with it that would include the image processing techniques for a variety of applications (e.g., a course on high-speed imaging). The scope of this project will be to create …

Molecular Sensing And Imaging Of Human Disease Cells And Their Responses To Biochemical Stimuli, Lifu Xiao
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Advancement in microscopic and spectroscopic techniques could significantly improve our ability in the study and diagnosis of diseases. Especially, being able to image and detect human diseases at the cellular and molecular level allows people to diagnose diseases at early stages and to study the molecular mechanisms behind various diseases. Currently, histopathological techniques are most widely used for prognosis and diagnosis of human diseases. However, conventional histopathology requires a complex process of sample preparation, which limits the diagnostic efficiency of this technique. More importantly, it requires fixation of tissue or cell sample, making it unsuitable for the study of dynamic …
