Optical Quartz Crystal Microbalance (OQCM) for Dual-Mode Analysis
(2018)
Label-free biosensors allow for real-time measurements of the target molecule, providing valuable kinetic data about the unperturbed biological system. Yet, they generally rely on a single transduction mechanism that ...
Extensions of Retrospective Cost Adaptive Control: Nonsquare Plants, and Robustness Modifications.
(2013)
Controllers that have adjustable parameters, and an update law for adjusting these parameters,
are called ``adaptive controllers''. Adaptive controllers typically entail assumptions about
the dynamic order, relative degree ...
Probing Heat Transport and Energy Conversion at the Atomic and Single Molecule Scale
(2018)
The study of heat transport and energy conversion constitutes an important subject in modern physics and engineering research. The widely-applied Fourier’s and Planck’s laws have proven to be very useful to describe heat ...
Modeling and Improving Teleoperation Performance of Semi-Autonomous Wheeled Robots
(2017)
Robotics and unmanned vehicles have allowed us to interact with environments in ways that were impossible decades ago. As perception, decision making, and control improve, it becomes possible to automate more parts of robot ...
Machine Learning for Identification and Optimal Control of Advanced Automotive Engines.
(2013)
The complexity of automotive engines continues to increase to meet increasing performance requirements such as high fuel economy and low emissions. The increased sensing capabilities associated with such systems generate ...
High Performance Piezoelectric MEMS Microphones.
(2010)
Piezoelectric microphones have been designed, fabricated using MEMS techniques, and tested. These designs are aimed at minimizing the noise floor as this has limited the applicability of previously constructed piezoelectric ...
High-Throughput, Continuous Nanopatterning Technologies for Display and Energy Applications.
(2010)
The motivation of this work is to enable continuous patterning of nanostructures on flexible substrates to push nanoscale lithography to an entirely new level with drastically increased throughput.
The Roll-to-Roll ...
Verification and Anomaly Detection for Event-Based Control of Manufacturing Systems.
(2010)
Many important systems can be described as discrete event systems, including a manufacturing cell and patient flow in a clinic. Faults often occur in these systems and addressing these faults is important to ensure proper ...
Experiments and Modeling of PEM Fuel Cells for Dead-Ended Anode Operation.
(2010)
This thesis develops models for the design and control of Dead-Ended Anode (DEA) fuel cell systems. Fuel cell operation with a dead-ended systems anode reduces fuel cell system cost, weight, and volume because the anode ...
Recursive Parameter Estimation using Polynomial Chaos Theory Applied to Vehicle Mass Estimation for Rough Terrain.
(2011)
This dissertation uses polynomial chaos theory to address recursive parameter estimation in state space systems. It joins the recursive estimators with base excitation modeling concepts to determine the mass of off road ...
