Three-Dimensional Anti-Jamming Array Processing for GNSS-Based Navigational Aid Inspection
(2023-05-12)
Global Navigational Satellite System (GNSS) Radio Frequency (RF) links are susceptible to interference. In signal compromised environments, the capability to combat RF interference (such as jamming) is necessary. Techniques ...
Automatic picking and classification of acoustic emission event arrivals
(2010)
Accurate automatic classification and picking of arrival times of events from acoustic emission (AE) signals is of considerable importance for rapid identification and location of seismic events. Due to the large number ...
A study on diffusion probabilistic models for image generation
(2023-12-15)
Diffusion probabilistic models have emerged as powerful tools for image generation and synthesis tasks. This research delves into the intricate relationship between the hyperparameters of these models and the underlying ...
Highly Miniaturized VHF Helical Filters with Fully Reconfigurable Capabilities
(2019-05-10)
The demand for frequency reconfigurable bandpass and bandstop filters within the VHF-UHF frequencies continues to rise due to the increasingly crowded radio frequency (RF) spectrum. As a result, higher levels of isolation ...
Toolbox and Post-Processing Applications for Automotive Radar
(2021-12-17)
In recent years, companies have pushed the limits to offer partial and fully autonomous driving systems. All vehicles now have a wide array of sensors to aid in driving, ranging from lane assist to automated parallel ...
Traffic accident analysis and prediction using the NPMRDS
(2020-12)
Traffic accidents are incidents caused by collisions between road vehicles or a vehicle with road infrastructures or pedestrians. Traffic accidents are a common cause for non-recurring traffic bottlenecks that, in turn, ...
Creeping Wave Propagation On Cylindrical Radiating Structures
(2019-08-01)
Weather radar is a powerful tool for detecting hazardous weather that may impact
the lives of many. Most weather radars used by meteorologists today rely on a
mechanical sweep to obtain volumetric data. This mechanical ...
Analysis of the Nyquist Folding Receiver (NYFR)
(2018)
Increased utilization of the radio frequency spectrum motivates receivers with wide instantaneous bandwidth for applications such as signals intelligence, cognitive radio, and compliance testing. Traditional wideband ...
AI BASED FAULT DIAGNOSIS IN EMERGING CELLULAR NETWORKS
(2019-08)
Mobile cellular network operators spend nearly a quarter of their revenue on network management and maintenance. A significant portion of that budget, is spent on resolving faults diagnosed in the system that degrade or ...
A Novel Method for the Characterization of Anisotropic Materials
(2018-12-14)
This thesis details the successful conceptualization, development, and proof of concept testing of a novel system for the characterization of a material's electromagnetic properties. In particular, the proposed system was ...
