Toward Precise Long-Range Underwater Acoustic Geo-Positioning: Utilizing Vehicle Data And Deepening The Gnss Analogy Through Uncertainty Modeling, Isaac B. Salazar

Open Access Master's Theses

Electromagnetic signals, such as those used by Global Navigation Satellite Systems (GNSS), attenuate dramatically underwater, but acoustic signals can travel hundreds of kilometers, and can be used for positioning in much the same way. Concepts from GNSS can be applied to the subsurface context, as at a basic level, the principles of geo-positioning are identical. Key challenges in translating satellite positioning models to the underwater acoustic domain include differences in signal type as well as instrumentation and propagation environment. Acoustic signals travel at much slower speeds and are subject to significant environmental variability due to complex ocean dynamics. Here, the …

Optical-Link-Aware Online Waypoint Planner For Asv-Auv Systems, Ansel R. Austin

Open Access Master's Theses

The growing demand for ocean mapping and survey missions has increased interest in reliable AUV-ASV platforms. In such systems, reliable communication between the AUV and ASV is critical for monitoring the AUV's status and offloading large data products such as multi-beam sonar point clouds. While the range of acoustic telemetry can span several kilometers, its bandwidth is inadequate for transmitting high-volume data streams (such as images and point clouds). Underwater optical communication modems, in contrast, provide a relatively high bandwidth but are hindered by rapid attenuation in turbid water and a narrow field of view. This thesis introduces an online, …

Exploring Area And Performance Benefits Of Programmable Logic Integrated Cpu Core, Jonathan Pollard

Open Access Master's Theses

This work proposes replacing fully static ASIC functional units with programmable functional units that leverage tightly integrated programmable logic within CPU cores. The programmable units can be configured to match the execution behavior of a specific workload while still allowing the CPU to remain general-purpose across all workloads. This approach reduces the total area required for functional units without sacrificing performance. We evaluate two configurations: an Ideal implementation, where programmable and ASIC functional units have equal area, and an Area-Larger implementation, where programmable units occupy twice the area of their ASIC counterparts. To establish feasibility, we first conduct binary instrumentation …

Addressing this imbalance requires data-driven tools that capture the realities of fleet operation and translate complex telemetry into actionable insight.

This dissertation introduces a unified machine-learning framework that operates exclusively on high resolution time-series data collected from fifty-nine diesel trucks deployed across Southern California. It begins by constructing a multi-modal feature space that blends statistical summaries of key engine signals, static vehicle descriptors, and Mel-Frequency Cepstral Coefficients, thereby …

Deep Target Recognition: Semi-Supervised Annotation, Sensor Fusion And Super-Resolution, Shoaib Meraj Sami

Graduate Theses, Dissertations, and Problem Reports (ETD)

Despite the recent expansion of machine learning algorithms to cover a wide range of disciplines, several areas of automatic target recognition (ATR) remain underexplored. This dissertation presents tools developed to improve performance in three significant aspects of ATR: semi-supervised annotation, sensor fusion, and image super-resolution. The aim of the semi-supervised methods is to automatically annotate targets in scenarios where labeled data are scarce in the target domain but available in the source domain. Secondly, to address the limitations of individual image sensors and enhance robustness under different environmental conditions and man-made constraints, a sensor fusion algorithm was developed to improve …
