Thermodynamic Model and Initial Experimental Investigation of Air Dehumidification through Electrically Charged Vapor Capturing Electrostatic Droplets
(2022-04-18)
The removal of water vapor from the air to reduce relative humidity is a well known indoor environmental comfort requirement. Common dehumidification approaches require a substantial amount of energy and usually involve ...
Design, Fabrication and Testing of Novel Medical Facemasks to Prevent COVID-19
(2022-04-28)
The nation is going through an unprecedented time due to the Coronavirus pandemic. One of the most effective ways to prevent viral spread is to use face masks and respirators. Available reusable face masks are often not ...
Investigation into MEMS Gyroscope Response in a High Frequency Environment
(2022-04-29)
Microelectromechanical system (MEMS) gyroscopes first emerged in 1991 as an alternative to the heavy, power hungry spinning mass gyroscopes. These devices opened new
frontiers for the ability to sense and control with ...
Observability-Informed Measurement Validation for Visual-Inertial Navigation
(2022-05-04)
This thesis presents a measurement validation method for visual-inertial navigation and an
implementation of a visual-inertial estimator which makes use of it. Many autonomous plat-
forms, especially flying ones, rely ...
Prognostics and Remaining Useful Life Estimation of Electronic Assemblies under Shock and Combined Temperature-Vibration Experiments
(2022-05-04)
The electronics components experience different high-stress loading environments such as drop, shock, and vibration at various life-cycle stages, i.e., manufacturing, transportation, and deployment in the field. In this ...
Measurement and Modeling of Damage in Mechanically Cycled Lead Free Solders
(2022-06-29)
Solder joints in electronic packages often experience fatigue failures due to cyclic mechanical stresses and strains in fluctuating temperature environments. This cyclic loading of the solder is induced by mismatches in ...
Experimental and numerical study of sooting tendency of IBE in a laminar diffusion flame
(2022-07-15)
Recent advancements in metabolic engineering have demonstrated that through cost-effective batch fermentation processes, isopropanol-butanol-ethanol (IBE) can be produced at sufficient quantities from switchgrass biomass. ...
Investigating the Process-Structure-Property Relationships of Additively Manufactured 17-4 Precipitation Hardening Stainless Steel
(2022-07-28)
The present work aims to investigate the process-structure-property relationships for the additively manufactured 17-4 PH stainless steel to improve its mechanical performance. To this end, a multidisciplinary (i.e., ...
Nonlinear Measures for Biomechanical Assessment of Movement Health and Postural Complexity
(2022-07-28)
The focus of this dissertation is on using nonlinear dynamics to analyze traditional biomechanical movements. The benefit of this approach is that nonlinear dynamics may be used in the future to help athletes avoid injury ...
