Effects Of Microplastic On Freshwater Benthic Ecosystems: Toxicity And Impacts On Biogeochemical Cycling, Kristina Chomiak Jul 2021

Effects Of Microplastic On Freshwater Benthic Ecosystems: Toxicity And Impacts On Biogeochemical Cycling, Kristina Chomiak

Theses

The accumulation of plastic debris in waterways is an increasingly complex environmental problem due to the ubiquity and magnitude of plastic debris across freshwater ecosystems, along with the unknown impacts on ecosystems and public health. However, “plastic” is a catchall term for numerous polymers with unique physical and chemical properties. Further complicating the prediction of risk, plastic characteristics may change from environmental exposure, with changes in density, adsorption or leaching of toxins, and accumulation of biofilms that further influence material properties, fate and impact. Recent studies suggest that a substantial proportion of plastic entering freshwater systems is deposited in the …

We propose a novel system for communicating musical note pitch and sequence information to users within a virtual reality environment. Our approach utilizes ‘Blooms,’ objects that resemble flowers with various petal arrangements. These formations, when constructed in view of users, act as diegetic, user-parsable encodings of their inputs. Blooms exist within the virtual space as simulated physics objects that collectively serve the role of a user interface.

Designing Blended Experiences: Laugh Traders Design Fiction, Brian J. Okeefe Jul 2021

Designing Blended Experiences: Laugh Traders Design Fiction, Brian J. Okeefe

Frameless

The increasing ubiquity of interactions that involve complementary digital content, physical objects, and spaces, brings about new challenges for designers. There is a need to embed designs in legacy systems, whether those are existing physical structures or existing digital platforms. Traditional approaches to product design, interaction design, and user experience design often do not take this new context into account. Many systems do not consider how designers produce new digital and physical experiences that work harmoniously, while supporting new interactions and relationships with people (Imaz and Benyon 2007; Jetter, Geyer, Schwarz & Reiterer 2012).

Pandemic Transformation Of Teaching And Learning: Designing Pedagogy Using The Contents Of Instructors’ “Pedagogical Pantry,” Rather Than “Established Recipes.”, Sara Schley, Carol E. Marchetti

Articles

How can faculty successfully shift from a physical classroom environment to creating meaningful online learning experiences in the midst of a pandemic? Using a “kitchen pantry” metaphor, this essay suggests faculty use a “what’s in my pantry?” approach, rather than trying to replicate the in-class experience and following a previously identified “recipe.” Some faculty embrace new technology options with great gusto. Others are resistant; and still others wait until they’ve seen others use it first to consider incorporating it. This model allows for different entry points of interaction, and for different levels of experimentation, reflecting individual faculty’s strengths and capabilities. …

Effect Of Nanoparticle And Acoustic Assisted Spalling On Iii-V Thin Film Photovoltaic Device Characteristics, David Smith Jul 2021

Effect Of Nanoparticle And Acoustic Assisted Spalling On Iii-V Thin Film Photovoltaic Device Characteristics, David Smith

Theses

Thin film III-V photovoltaics (PV) are a high efficiency, low weight alternative to silicon. However, high costs make practical use cases limited to weight specific applications. These high costs are largely contained in material costs and especially thick substrates used as seed and handle layers for devices grown atop them. Removal and reuse of the substrates post device growth leads to a significant reduction in the material cost to make these devices. Acoustic assisted spalling (Sonic Wafering) is a low-cost substrate removal method that has the potential to significantly reduce costs related to the fabrication of III-V PVs. This thesis …

An Enhanced Statistical Phonon Transport Model For Nanoscale Thermal Transport And Design, Michael P. Medlar Jul 2021

An Enhanced Statistical Phonon Transport Model For Nanoscale Thermal Transport And Design, Michael P. Medlar

Theses

Managing thermal energy generation and transfer within the nanoscale devices (transistors) of modern microelectronics is important as it limits speed, carrier mobility, and affects reliability. Application of Fourier’s Law of Heat Conduction to the small length and times scales associated with transistor geometries and switching frequencies doesn’t give accurate results due to the breakdown of the continuum assumption and the assumption of local thermodynamic equilibrium. Heat conduction at these length and time scales occurs via phonon transport, including both classical and quantum effects. Traditional methods for phonon transport modeling are lacking in the combination of computational efficiency, physical accuracy, and …

Improvements And Analysis Of Challenging Numerical Simulations Of Binary Black Holes, Nicole Rosato

Theses

We explore different gauge choices in the moving puncture formulation in order to improve the accuracy of a linear momentum measure evaluated on the horizon of the remnant black hole produced by the merger of a binary. In particular, motivated by the study of gauges in which the damping term in the shift m eta takes on a constant value, we design a gauge via a variable shift parameter m eta(r(t)). This parameter takes a low value asymptotically, 1/m, and then takes on a value of approximately 2 at the final hole horizon. This eta then follows the remnant black …
