Modelling, Control and Estimation Techniques For Micromachined Electrostatic Actuators Using Macro Magnetic Actuators
(2016-07-29)
Parallel plate actuators (PPAs) are fundamental devices in micro-electro-mechanical systems. PPAs' main drawback is their limited open loop stable traveling range which is caused by their nonlinear electrostatic force. ...
Synthesis, Processing and Dynamic Fracture Behavior of Particulate Epoxy Composites with Conventional and Hierarchical Micro-/Nano-fillers
(2016-12-09)
Polymer-based particulate composites have a wide range of engineering applications due to their mechanical, chemical, dielectric, and lightweight characteristics as well as simplicity of processing. The mechanical performance ...
Classification of Ego Platform Motion for Platform Independent Plug and Play Navigation
(2016-05-05)
This dissertation presents a method of using these kinematic constraints without requiring this apriori knowledge of the application platform. The method is termed ``joint navigation and classification'' (JNC), and involves ...
Magnetometer Aided Navigation Filters for Improved Observability and Estimation on Ground Vehicles
(2016-07-29)
Two modified extended Kalman filters, called the MGVA and MVVA filters, have been developed which combine the attitude determination capabilities of magnetometers with the standard extended Kalman filter. The standard ...
A Multiple-Antenna Software GPS Signal Simulator for Rapid Testing of Interference Mitigation Techniques
(2016-12-12)
This thesis details the design of a software GPS signal simulator and illustrates how it can be used to support rapid testing of GPS interference mitigation research. The MATLAB-based signal simulator is capable of generating ...
Managing the Effects of Heat, Dust, and Vibration on a GPS Receiver in a Desert Environment
(2016-04-22)
Applications for personal handheld electronic devices, such as GPS receivers, have significantly increased in recent years. It is now necessary for such devices to be able to operate in a wide variety of harsh environmental ...
Incorporation of a Foot-Mounted IMU for Multi-Sensor Pedestrian Navigation
(2016-04-29)
This thesis deals with pedestrian localization by way of multi-sensor fusion. A special focus is made on the use of a foot-mounted inertial measurement unit (IMU) and its incorporation into other pedestrian navigation ...
A Nonlinear Model Predictive Control Algorithm for an Unmanned Ground Vehicle on Variable Terrain
(2016-12-12)
This thesis presents a Nonlinear Model Predictive Controller (NMPC) for an Unmanned Ground Vehicle (UGV) capable of controlling the vehicle over both smooth and rough terrain using measurements from GPS and a Light Detection ...
Application of Low Melt Alloys as Compliant Thermal Interface Materials: A Study of Performance and Degradation under Thermal Duress
(2016-07-08)
Thermal interface materials (TIMs) are a crucial part of thermal management in micro-electronics and often can account for a significant portion of the overall thermal budget. Generally, materials with high thermal ...
Simultaneous Localization Auto-Calibration and Mapping of Ground Vehicles
(2016-06-17)
This dissertation advances the state of the art of sensor auto-calibration by presenting a generic solution and analysis to the 3D sensor auto-calibration problem, as well as to the 2D simultaneous localization and ...
