Multiple Secondary Risks Triggered By Rapid Rising Of Groundwater Level And Corresponding Tactics In The North China Plain, Yanjun Shen, Fubao Sun, Congqiang Liu, Fengchang Wu

Bulletin of Chinese Academy of Sciences (Chinese Version)

In recent years, following the implementation of the South-to-North Water Diversion Project and comprehensive control of groundwater over-exploitation, coupled with natural factors such as more frequent and intensified extreme rainstorms, the groundwater level at large extent of the North China Plain has stopped declining and even started rising, with gradual recovery of groundwater storage. Nevertheless, the rapid rise in groundwater levels has disrupted the long-standing hydrological-geological-ecological balance shaped by prolonged over-extraction, triggering multiple secondary risks. The rebounding water level markedly exacerbates potential seismic liquefaction hazards at construction sites and raises risks of water seepage, anti-float failure, and structural damage for …

Developing Field And Spaceflight Microscopy, Nikki Johnston

Dissertations and Theses

Designing for spaceflight favors the reduction of unnecessary features and cost-cutting, whether thisbe computation, hardware, or procedure. Resources are spent toward fortification and mission success over convenience. Such design goals paired with the relatively smaller budgets of academia lead us to do as much as we can in-house and use open-source as much as we can without compromising mission success. We also believe that thoroughly testing technology in extreme environments on earth is necessary for the success of a flight instrument. We focus on microscopy for life detection. I have spent my time here learning methods of hand-building microscopes to …

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Biobased lubricants with thermally responsive rheology are increasingly needed for high-efficiency mechanical systems. Graphene nanoplatelet (GnP) nanofluids in vegetable oils are promising candidates, yet their percolation-driven thermo-rheological transitions remain insufficiently understood. In particular, the coupled concentration–temperature landscape controlling network-mediated flow transitions has not previously been established. Here, surfactant-free GnP nanofluids were prepared in high-oleic soybean oil (HOSO) at concentrations of 0.025–2.15% v/v (ϕ), and their rheological response was mapped between 25°C and 80 °C under steady-shear and oscillatory conditions. Below the percolation threshold (ɸ ≤ 0.1% v/v), the nanofluids exhibit near-Newtonian behavior, moderate reversible viscosity enhancement, and classical Arrhenius-type temperature …

Evaluating A Dual-Beacon Hartmann Turbulence Profiling Technique Using Wave Optics Simulations, Benjamin C. Wilson, Matthew Kalensky, Santasri Bose-Pillai, Jack E. Mccrae

Faculty Publications

Resolving how optical turbulence varies along a propagation path remains a key challenge for designers of free-space optical propagation systems. Instruments such as scintillometers and differential image motion monitors are commonly used, but only provide path-integrated turbulence estimates. Point sensors provide localized estimates of turbulence strength and can be used to generate path-resolved profiles when an array of point sensors are distributed along the optical path. However, this approach can be costly and complex to deploy in certain environments. Alternatively, a single point sensor can be mounted on a mobile platform that collects data while traversing the optical path, although …

Workers Authoring Assessment: Play And Power In Early Childhood Education, Phoebe M. Gilpin

Theses and Dissertations

Researchers assert that play-based pedagogy is an effective approach to teaching young children, but there is less consensus on the specific methods of play-based teaching. This mixed-methodology exploratory case study investigated early childhood (EC) educators’ conceptualizations of play-based pedagogy in three phases: Phase 1’s quantitative measure testing found a mismatch between researchers’ conceptualization of play-based pedagogy and EC educators’ (n=183) understandings. In Phase 2, EC educators (n=3) articulated their perspectives about teaching through play and co-authored a new tool, the Teacher-Authored Play and Teaching Scale (TAPTS). Within Phase 3, EC educators (n=60) completed the TAPTS, which I interpreted through a …

Structured And Interpretable Representations For Ensemble And Dynamical Systems, Yuan-Hung Kuan

McKelvey School of Engineering Graduate Student Theses & Dissertations

Precise and robust manipulation of large populations of structurally identical dynamical systems with heterogeneous dynamics, known as ensemble systems, is a central challenge in many emerging applications. These systems are often difficult to analyze and control because of the inherent nonlinearities, high dimensionality, heterogeneity, and incomplete knowledge of the underlying dynamics. To address these challenges, this thesis develops structured and interpretable representations for the analysis, control, and learning of nonlinear ensemble systems. Its central objective is to transform complex heterogeneous dynamics into representations that preserve essential structural and dynamical properties while enabling tractable computation and effective control design.

Tracing Caribbean Narratives At The Intersection Of Language, Identity, And Social Media, Juan-Carlos M.E. Goilo

archipelagos: a journal of Caribbean digital praxis

This article delves into how the creole language of Papiamentu navigates the complexities of cultural identity and decolonial praxis within the social media landscape. Drawing from literature reviews, digital ethnography, content analysis, and an interview with social media influencer Gerald Lijde, I explore Papiamentu’s deep-rooted colonial ambivalence—a legacy that shapes its contemporary online use. While digital platforms offer new avenues for celebrating and formalizing Papiamentu, they also risk commodifying its radical, anti-colonial roots into tourist-friendly narratives. By linking online content production to theories of agency and digital culture, the article illuminates Papiamentu’s enduring role as a vessel of resistance and …

Theoretical Model For A Poroelastic Membrane Under Uniform Load, Minh Duc Nguyen

OneUSF Summer Undergraduate Research Symposium

Flexible membrane wings appear throughout both natural and engineered flyers — parachutes, sails, birds, and bats — and are known to confer favorable aerodynamic characteristics through deformation in response to the surrounding flow. To date, flexibility and porosity have largely been studied in isolation, yet in a poroelastic membrane the two are coupled: as the membrane extends under load, its pores stretch with the surface. This study takes the first step toward analyzing that coupling by characterizing how the effective elasticity of the membrane depends on its porosity under uniform static pressure. Circular clamped membranes were simulated across a range …

Effects Of A Low-Dosage Bilingual Oral Language Intervention On Language Outcomes Among Dual Language Learners, Dana S. Melik

OneUSF Summer Undergraduate Research Symposium

Dual language learners (DLLs) represent one of the fastest-growing populations in the United States, and many continue to receive English-language instruction with limited bilingual language support (Lindholm-Leary, 2022). Because oral language development is associated with later academic outcomes (Spencer & Petersen, 2020), evidence-based bilingual oral language interventions are needed, particularly in underserved schools where staffing and resources are limited. The present study examined the effects of Story Champs Bilingual Edition 2.0 (SCBE2.0), a narrative-based Spanish-English oral language intervention, on language outcomes among Spanish-English DLLs when delivered by trained nonteacher personnel at a low dosage. English and Spanish oral language outcomes …

Open-Source Software For Computing Code Automorphisms, Mateo Fernandez-Tyson, Gianna Baker

OneUSF Summer Undergraduate Research Symposium

An error-correcting code is a mathematical structure that models the flow of information through a noisy communication channel and seeks to mitigate errors through redundancy. These codes have a wide range of uses spanning from satellite transmissions to cryptographically secure communication schemes. An automorphism of a code is a permutation of the coordinate positions that preserves the code, and these symmetries are useful in helping to answer questions of code equivalence, classification, and decoding. Our work focuses on implementing and testing algorithms for code automorphism computation using GAP and the GUAVA package. We present an efficient algorithm for generating all …

On Shrinkage Estimators For Pareto Ii Parameters For Right Censored Type Ii Data, Jubran Abdulameer Labban, Hadeel Alkutubi

Iraqi Journal for Computer Science and Mathematics

The aim of this study is to estimate the first two shrinkage estimators for the parameters of the Pareto II distribution with right-censored Type II data. The methods we used in this study are: maximum likelihood and Bayesian. In the Bayesian method, we use non-informative priority, which is Jeffries priority, and we use the squared error loss function. These estimators were compared through Monte Carlo simulation to indicate preference based on the mean square error criterion.
