Adaptive Steering Actuator Delay Compensation for a Vehicle Lateral Control System
(2023-05-01)
This thesis presents an adaptive control algorithm for steering actuator delay compensation in a ground vehicle lateral control system. Unknown and time-varying actuator delay values are considered. Many active safety ...
Mechanical and Microstructural Behavior Evolution of Lead Free Solder Materials Under Different Thermal Exposures
(2023-05-01)
With the growth of electronic packaging industries, ranging from automobile to hand-held products, reliability is a major concern. Also, to keep pace with the increasing demand of end users for integration, miniaturization, ...
Study of onset of frost and crystals growth on hydrophilic and hydrophobic flat surfaces
(2023-05-02)
Air-source heat pump systems extract heat directly from the cold outdoor ambient and reject heat to the warm indoor environments of residential and commercial buildings. During their winter operation, the outdoor coil often ...
Spray Evaporation on Enhanced-Surface Tube Bundles with Low-GWP Refrigerants
(2023-05-04)
With the development of new low-GWP HFO refrigerants and increasingly stringent regulation of existing HVAC&R systems, the heat transfer performance of these refrigerants and the effects of various enhancement techniques ...
A Multi-Antenna Vector Tracking Beamsteering GPS Receiver for Robust Positioning
(2022-05-17)
This thesis proposes the coupling of a Global Positioning System (GPS) L1 C/A vector tracking software-defined receiver with controlled reception pattern array array (CRPA) satellite constrained beamsteering, i.e. a ...
Additive Manufacturing of Engineered Polymeric Flexible Structures
(2023-05-15)
Polymer-based additive manufacturing (AM) processes allow the flexibility, rapid, and low-cost fabrication of complex geometries. In recent years, fused filament fabrication (FFF), also known as fused deposition modeling ...

(2023-07-18)
This thesis has been redacted.
Experimental Characterization of Battery Performance under Non-Uniform Temperature Gradient
(2023-07-27)
In order to ensure optimal performance of the batteries, a thermal management system (TMS) is suited in electric vehicles for the temperature control. However, due to the non-uniform heat generation of the large format ...
A Loosely Coupled GNSS/PDR Integration Approach for Pedestrian Navigation
(2023-07-28)
Pedestrian navigation systems embody small, lightweight hardware, techniques, and biomechanical information to provide positioning information in an architecture that substitutes, or supplements, traditional systems such ...
A ROUGH SURFACE MIXED LUBRICATION MODEL OF MACHINE COMPONENT INTERFACES WITH AN EXPERIEMENTAL EVALUATION
(2023-05-02)
This work develops a numerical methodology for predicting the performance of
an automotive piston ring system by considering contact and lubrication mechanics. The
rough surface contact mechanics and lubrication occurs ...
