Evaluating A Dual-Beacon Hartmann Turbulence Profiling Technique Using Wave Optics Simulations, Benjamin C. Wilson, Matthew Kalensky, Santasri Bose-Pillai, Jack E. Mccrae Aug 2026

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 …

Tracing Caribbean Narratives At The Intersection Of Language, Identity, And Social Media, Juan-Carlos M.E. Goilo Aug 2026

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 …

Infrastructure Of Lack: Defining Caribbean Vernacular Networks, Luis Rivera Jiménez Aug 2026

Infrastructure Of Lack: Defining Caribbean Vernacular Networks, Luis Rivera Jiménez

archipelagos: a journal of Caribbean digital praxis

This article offers a theoretical reflection on the forms and meanings of networks in the Caribbean, moving beyond traditional definitions rooted in computation and formal infrastructure. By turning to vernacular, improvised, and culturally embedded modes of exchange—such as in "Club Nintendo" culture and BlackBerry Messenger (BBM) in the Dominican Republic, the DIY internet practices of Cuban users, and the ubiquity of memes and WhatsApp threads across diasporic communities—this piece reframes the concept of the “network” through a Caribbean lens. Rather than seeing the Caribbean as disconnected or technologically incipient, this approach understands the region as a space of creative, strategic, …

Evaluating Biochar Composites For 3d Printing Wetland Restoration Media, Lily Boyer, Melody Ngaaso Aug 2026

Evaluating Biochar Composites For 3d Printing Wetland Restoration Media, Lily Boyer, Melody Ngaaso

OneUSF Summer Undergraduate Research Symposium

Nutrient pollution from urban stormwater and agricultural runoff drives eutrophication in coastal wetlands, threatening the ecological function of ecosystems that communities depend on for water quality, flood resilience, and habitat. Floating treatment wetlands offer a nature-based intervention, but conventional planting media provide limited nutrient adsorption capacity and little opportunity for design optimization at scale. This study investigates whether biochar, a porous, high-surface-area carbon material, can be incorporated into extrudable biocomposites to enhance ammonium, nitrate, and phosphate adsorption in floating wetland applications, while remaining safe for sustained contact with wetland plant roots. Four biochar composite recipes were fabricated as standardized cylindrical …

Chemical Effects Of Microplastics On Photochemistry In A Coral-Associated Zooxanthella, Meghan A. Hennings, Matz Indergard, John E. Parkinson

OneUSF Summer Undergraduate Research Symposium

Coral bleaching is the process by which corals lose their symbiotic microalgae in response to stressful conditions. These photosymbionts, known as zooxanthellae, give corals their color and sustain host growth through mutualistic nutritional exchange. Bleaching events are becoming more common and severe, driving research into coral conservation and the resilience of each partner in the symbiosis. Yet it is unknown how certain pollutants, such as microplastics, may affect bleaching outcomes. Previous research in our laboratory has demonstrated that the presence of polyvinyl chloride (PVC) microplastics inhibits bleaching recovery in sea anemones (a coral model), but it remains unclear whether the …
