Custom Test Point Insertion For Improved Rom Test Coverage, Krunal Siddhapathak, Ankit Garg

Defensive Publications Series

Read-only memories (ROM) incorporate a scan chain to assist in detecting manufacturing defects. This scan chain can share a single flip-flop across multiple ROM outputs. However, sharing of scan flip-flops across ROM outputs can create a controllability issue for the ROM fan-out logic. Testing ROM fan-out becomes challenging, as a single control element drives four outputs, each with potentially different requirements for fault excitation and detection. This disclosure describes techniques that insert custom test points to improve the controllability and observability of the fan-out and fan-in logic cones of read-only memories (ROMs). By placing test points at the ROM outputs, …

Between Shelter & Ash: A Design Policy Atlas For Wildfire-Resiliency, Daisy Elizabeth Morales-Zaragoza

McNair Summer Research Program

Architectural design holds a powerful potential in the face of wildfire threats, yet remains underutilized in fire resilience strategies. This study will explore how design, at the level of the house, street, and community, can move beyond code compliance toward holistic protection. Through analysis of principal fire codes such as IWUIC, CBC Chapter 7A, and NFPA 1144, visual diagrams, precedent case studies, and original architecture proposals, the paper proposes a multiscale design framework that expands our understanding of resilience. It argues that while fire codes establish critical baselines, spatial planning, form, and materials must work in concert with social and …

Chemically Mediated Communication In Mound-Building Termites, Sree Subha Ramaswamy

Theses and Dissertations

Nest-building in social insects requires layered communication to coordinate complex, functional structures for housing, protection, storage, and homeostasis. This is especially striking in mound-building termites, which construct and repair large mounds collectively despite lacking image-forming eyes. This thesis investigates how Odontotermes obesus achieves such coordination through chemical communication embedded in soil.

Using controlled two-choice assays with manipulated soils, I separated airborne volatile signals from contact non-volatile signals by baking to remove volatiles, a mesh assay that presented volatile cues without contact, and solvent extraction with reapplication of contact cues. I quantified responses in major-only, minor-only, and mixed groups at two …

Investigating Techniques To Optimise The Layout Of Turbines In A Windfarm Using A Quantum Computer, James Hancock, Matthew Craven, Craig Mcneile, Davide Vadacchino

School of Engineering, Computing and Mathematics

This paper investigates Windfarm Layout Optimization (WFLO), where we formulate turbine placement considering wake effects as a Quadratic Unconstrained Binary Optimization (QUBO) problem. Wind energy plays a critical role in the transition toward sustainable power systems, but the optimal placement of turbines remains a challenging combinatorial problem due to complex wake interactions. With recent advances in quantum computing, there is growing interest in exploring whether hybrid quantum-classical methods can provide advantages for such computationally intensive tasks. We investigate solving the resulting QUBO problem using the Variational Quantum Eigensolver (VQE) implemented on Qiskit’s quantum computer simulator, employing a quantum noise-free, gate-based …

Theses

The accumulation of anthropogenic debris (AD) in the Great Lakes is a growing issue with largely unknown consequences for ecological and human health. To better constrain estimates of debris loading into Lake Ontario and elucidate the fate of AD accumulating upstream, an incubation experiment of the most commonly identified littered products was conducted in different stormwater infrastructure within the Lake Ontario Watershed. Chip bags, cigarette filters, and shopping bags were placed into storm drains, stormwater retention ponds, and along riparian zones of tributaries in December of 2022 and July of 2023 to test the spatial (type of stormwater infrastructure [SWI]) …

An Rna Modification Prevents Extended Codon-Anticodon Interactions From Facilitating +1 Frameshifting, Evelyn M. Kimbrough, Ha An Nguyen, Haixing Li, Jacob M. Mattingly, Nevette A. Bailey, Wei Ning, Howard Gamper, Ya-Ming Hou, Ruben L. Gonzalez, Christine M. Dunham

Department of Biochemistry and Molecular Biology Faculty Papers

RNA post-transcriptional modifications act by stabilizing the functional conformations of RNA. While their role in messenger RNA (mRNA) decoding is well established, it is less clear how transfer RNA (tRNA) modifications outside the anticodon contribute to tRNA stability and accurate protein synthesis. Absence of such modifications causes translation errors, including mRNA frameshifting. By integrating single-molecule fluorescence resonance energy transfer and cryogenic electron microscopy, we demonstrate that the N1-methylguanosine (m1G) modification at position 37 of Escherichia coli tRNAProL is necessary and sufficient for modulating the conformational energy of this tRNA on the ribosome so as to suppress +1 frameshifting otherwise induced …

Civil and Environmental Engineering Faculty Publications

Colorado River users are now discussing dividing river flow on a percentage basis (Fleck, 2025; Hager, 2025, Winslow, 2025). This is an important step to managing a declining and more volatile supply. In our prior May 2025 post, we shared a strategy we have worked on for several years— division of river flow—as one of 13 reasons why we have hope for consensus on Colorado River management. In this post, we address the question: How extreme low river flow and reservoir storage should we plan for going forward (Figure 1)? We also share our insights from numerically stabilizing and recovering …

High Temperature In Potato: Plant Responses And Adaptive Cultivation Strategies To Increase Production, Siska Rahmayani Gultom, Jajang Sauman Hamdani, Kusumiyati

Jurnal Kultivasi

Climate change, with global temperatures rising by 1.09°C from 1850–1900 to 2011–2020, threatens potato production, a critical staple crop, by exceeding the optimal temperature range of 15–20°C. This review synthesizes over 45 peer-reviewed studies published between 2015 and 2025 from Google Scholar and ScienceDirect to evaluate the physiological, morphological, and tuber quality responses of potatoes to high temperatures and to identify adaptive cultivation strategies for sustainable production. High temperatures reduce photosynthetic efficiency through chlorophyll degradation and stomatal closure, increase respiration, and divert photosynthates to vegetative growth, leading to 18–32% yield losses globally by the 2050s. Heat-tolerant varieties, such as Atlantic …

Versatile Waveform Generation And Clocking Techniques For Rfsoc-Based Digital Designs, Michael David Jones

Theses and Dissertations

Within an ever-evolving radio-frequency (RF) environment, designers are required to adapt systems to increasingly constricted parameters. The available tools continually grow to match this need, but so does the complexity in using them. The radio-frequency system-on-chip (RFSoC) is an innovation that combines a field-programmable gate array (FPGA) with an integrated RF chain. Designing with an RFSoC allows for high-precision data transmission, sampling, and processing, but it can be difficult and time-consuming to develop specialized circuits. The open-source CASPER project aims to provide a library of abstracted block-design components to simplify the design process. An arbitrary waveform generator (AWG) is created …

Cmsi Translations #22: Implications Of The U.S. Navy's "Sea Base" Construction For Equipment Support In Cross-Sea Landing Operations, Tan Benhang

CMSI Translations

Cross-sea landing operations (跨海登陆作战) is one of the primary forms of warfare for which our military is preparing, both for the present and for a period into the future. How to provide timely, reliable, continuous, and efficient equipment support for cross-sea landing operations is a critical matter requiring urgent research. The U.S. military was the first to propose the operational concept of “seabasing” to enable sea-based logistics and equipment support for forward-deployed task forces, thereby providing critical sustainment for out-of-area military operations. This seabasing initiative has important implications and provides a valuable reference for enhancing our military's equipment support capabilities …

Accelerating Gnn Inference On Multi-Core Systems, Binglin Ji

McKelvey School of Engineering Graduate Student Theses & Dissertations

Graph Neural Networks (GNNs) are becoming increasingly popular, with their applications expanding across diverse domains. As the scale of graph data continues to grow, including larger numbers of nodes, edges, and higher embedding dimensions, standardized libraries such as DGL and PyG have been developed to facilitate GNN computation. However, with the rapid increase in the number of processor cores and the evolution of multi-core architectures, these libraries often show poor scalability and fail to execute GNN inference efficiently on the latest multi-core systems, particularly those with upwards of a hundred cores. To address this limitation, we present FGI, a Fast …

Multi-Objective Optimisation Of Floating Offshore Wind Farms Based On A Real-World Case Study, Pawel Manikowski, David Walker, Matthew Craven

School of Engineering, Computing and Mathematics

In this paper, we used real data to predict the position of the floating wind turbines due to three external forces: wind, wave and current. We analysed data provided by energy company Equinor and applied two machine-learning techniques: Multilayer Perceptron and Random Forest. After demonstrating that machine learning models failed, we used a simple linear regression model and optimisation approach to solve the multi-objective optimisation problem. We minimised the perimeter of the wind farm and maximised its power output by applying the multi-objective optimisation algorithm NSGA-II. We also investigated how changing the length of mooring lines affected the optimisation. We …

Enhancements And Improvements Of The Radiation Probe - Compact Radiation Probe (Crp), Yihsuan Chou, Loren Chang, Yichung Chiu, Tzuwei Hung, Sinyu Tsui

Small Satellite Conference

As space missions venture beyond Earth's magnetic field, spacecraft face elevated risks from solar energetic particles (SEPs) and galactic cosmic rays (GCRs). Taiwan's first lunar payload—the Deep Space Radiation Probe (DSRP)—was developed to measure radiation dose, dose rate, and SEU rates during Earth–Moon transit. However, flight data revealed limitations in SEU detection and system operation. To address these issues and support CubeSat-class missions, the Compact Radiation Probe (CRP) was developed for the upcoming COSPAR-1 mission.

It Shucks To Be Inbred: Effects Of Small Population Sizes On Genomic Diversity Of Hatchery Reared Olympia Oysters (Ostrea Lurida), Anna S. Heasley

Master's Theses

Olympia oysters (Ostrea lurida), critical members of estuarine ecosystems along the California Current Ecosystem (CCE), have faced significant population declines due to historical overfishing and habitat deterioration. Today, managers from multiple estuaries across the CCE are focusing on conservation aquaculture breeding efforts to aid in restoration; however, the genetic implications of these efforts remain unexplored. As with other Ostrea spp, Olympia oysters have a viviparous reproductive strategy that creates unique challenges for aquaculture-mediated restoration. This study evaluates the genetic impact of current captive breeding practices on Olympia oyster cohorts produced in three California estuaries: Elkhorn Slough (EHS), Morro Bay (MB), …

Environmental Science and Management Faculty Publications and Presentations

Understanding how water moves through a watershed is one of the most fundamental yet often complicated aspects of hydrology, especially in urban areas. Urban infrastructure and water management alter natural hydrological pathways in developed watersheds, which can violate assumptions of a watershed approach to ecosystem science. We focus on two aspects of urban landscapes that often create challenges to model watershed processes within and among urban areas: (1) accurate delineation of urban flow paths and (2) consistent characterisation of the urban landscape within and among cities. Here, we describe these challenges and identify how certain components of these challenges can …
