Exploring IMU Attitude and Position Estimation for Improved Location in Indoor Environments

Creator:: Zhang, Shengkai
Abstract:: Wearable sensors with an inertial measurement unit (IMU) are popular for indoor positioning and activity pattern detection. The IMUs can be connected to a wireless transmission module, allowing users to monitor and process motion-related parameters remotely. Because of the complexity and uncertainty of signals in indoor environments, a radio frequency...

Oxygenate Reactions over PdCu and PdAg Catalysts: Influence of Electronic and Geometric Effects

Creator:: Bathena, Tanmayi
Abstract:: Bimetallic catalysis is a promising way to tune the catalytic properties of heterogeneous catalysts. In particular, bimetallic catalysts are extensively used to enhance the selectivity of monometallic catalysts in a variety of contexts, from oxidation catalysis to oxygenate coupling. In this work, we investigate PdxCuy/SiO2 and PdxAgy/SiO2 catalysts in the...

Quantum dot plasmon coupling : Fundamental study and applications

Creator:: Kannegulla, Akash
Abstract:: The dissertation focuses on the engineering of light-matter interaction using plasmonic nanoparticles and metamaterials to achieve enhanced luminescence and based on which to improve the performance of biosensing and light-emitting technologies. We designed and fabricated a spectrum of nanostructures to exhibit particular dispersion relations capable of controlling the spontaneous emission...

The Influence of Fuel Characteristics on Smoldering Behavior through Porous Fuels

Creator:: Ross, Andrew H.
Abstract:: Smoldering can play a dangerous role in the ignition and spread of wildfires. Naturally occurring fuels consist of multiple layers of organic materials with varying particle sizes due to differences in decomposition stages with fuel depth, yet the influence of particle size on burning behavior is poorly understood. Previous research...

Characterization and theoretical analysis of the effect of geometry on electrical characteristics of flexible thin film transistors

Creator:: Chattopadhyay, Shirsopratim
Abstract:: Flexible Electronics is a fast developing technology that is set to revamp and revolutionize conventional electronics through the development of devices that are easily conformable to surfaces of any arbitrary geometry. Such devices would have vast applications in areas where the rigidity of traditional silicon based electronics is undesirable, such...

Machine Learning Applied to Non-periodic Event Detection – A Special Case in Structural Health Monitoring

Creator:: Hu, Congcong
Abstract:: Structural Health Monitoring (SHM) is known as the process of implementation of damage detection and characterization strategy. The method is widely used in modern critical equipment to minimize the risk of failures. While a significant effort has been devoted by researchers for the detection of faults in situations including periodic...

Signal Enhancement in Lateral Flow Tests for Infant HIV Diagnosis

Creator:: Rodriguez, Michael A.
Abstract:: Paper-based assays for HIV diagnosis are cheap, portable, and require little to no skilled training, electricity, or expensive equipment to perform successfully. However, there is a need for tests with lower limits of detection (LOD) for diagnosing infection at the earliest stages. Effective labeling to increase signal-to-noise ratio is critical...

Multi-Modal Biosensing with Diatom Photonic Crystal Biosilica

Creator:: Squire, Kenneth J.
Abstract:: The need to detect trace amounts of target molecules is great, particularly when it comes to biosensing. With the early detection of a disease, the odds of the successful treatment of an individual increases significantly. To enhance the capability of biomolecular detection, we have created an optical biosensor capable of...

High-performance Ring Amplifier based Analog-to-Digital Converters

Creator:: Hu, Hang
Abstract:: Ring Amplifier serves as a great candidate both for precision amplification and fast integration in the discrete time system. It can be utilized in high-performance analog-to-digital converters (ADCs). In high-speed ADC utilizing pipelined architectures with residue amplification, Successive-Approximation Register (SAR) ADCs as the sub-ADC and power efficient Ring Amplifier based...

Co-channel Blocker and Self-Interferer Tolerant Receiver Architectures for MIMO and Full-Duplex MIMO Receivers

Creator:: Jain, Sanket
Abstract:: This research focuses on receiver architectures which enable better spectral eciency by handling blockers in the same spectral range as the signal. The presence of such blockers, without the use of blocker cancelling/ltering techniques leads to gain compression and hence, consequent performance degradation of receivers leading to reduced spectrum...
