Improving Magnetic Map-Based Navigation using Vehicle Motion Information
(2022-01-06)
This thesis utilizes the earth's main magnetic field as the signal for a map definition, implements a particle filter to synthesize a solution from likelihood information, and introduces vehicle motion information by means ...
Investigation of Precise Relative Positioning through Varying Equipment Grades
(2022-02-22)
In this thesis, three methodologies are investigated in order to provide precise relative positioning knowledge between two dynamic platforms as equipment grade is varied. Two methods are integrated into the real-time ...
Design and Calibration of Stress Sensors on 4H-SiC
(2022-03-07)
Stresses in electronic packages due to thermal and mechanical loadings can cause premature mechanical failures such as fracture of die, severing of connections, die bond failure, solder fatigue, and encapsulant cracking. ...
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. ...
