Understanding Of Aerosol Transmission Of Covid 19 In Indoor Environments, Adama Barro, Cathal O'Toole, Jacob S. Lopez, Matthew Quinones, Sherene Moore

Publications and Research

Our reason for discussing severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) or 2019 novel corona virus (Covid-19), is to understand its aerosol transmission characteristics in indoor spaces and to mitigate further spread of this disease by designing a new HVAC system. The problem that we are tackling is the spread of covid-19 droplets through aerosol transmission by looking at potential engineering solutions to the existing HVAC systems. The purpose is to eradicate the spread of the COVID-19 by testing indoor spaces in an effort to understand the effectiveness of ventilation controls. We believe that scientists and engineers have not …

Developing A Portable, Smartphone-Based Schlieren Imaging System, Grace Riermann, Keith R. Stein

Honors Student Works

Schlieren imaging is a technique for visualizing fluid flows that are characterized by spatial variations in density or refractive index. Because schlieren imaging is commonly performed with expensive equipment in a lab setting, we sought cost efficiency, accessibility, and ease of fabrication by designing a portable, smartphone-based system.

Surface Geometry And Heat Flux Effect On Thin Wire Nucleate Pool Boiling Of Subcooled Water In Microgravity, Troy Munro, Andrew Fassman

Presentations

The motivation of this nucleate boiling research is to understand the effects of surface geometry and heat flux as applied to a thin wire heater. This will further the understanding of the fundamental behaviors of boiling onset, steady state heat transfer, and bubble dynamics with respect to nucleate boiling with the goal of creating efficient thermal management systems for future space applications. Using three different thin platinum wire geometries and five different power levels, subcooled water was boiled over a period of approximately 30 seconds for 15 parabolic arcs to simulate microgravity. To represent the trends in bubbles behavior across …

Institute Overview, Morton Sternheim

STEM Digital

Digital cameras and computers are widely available for students and teachers. However, they are mainly used for documentation: creating PPT presentations, handouts, posters, etc. STEM DIGITAL shows how digital image analysis can be applied to environmental (and other) research in STEM courses. Application to studies of air quality, water quality, arsenic contamination, climate change, diffusion, etc.

Measuring Albedo With Adi - An Intensity Application, Morton Sternheim

STEM Digital

Why are Polar Regions more affected by global warming than other parts of the globe? One reason (there are others) is that as sea ice melts and more open water appears, more energy is absorbed, and warming accelerates. This is a form of positive feedback and it makes the polar climate change faster than the climate in temperate areas. Increasing vegetation on land also has a similar positive feedback effect. This effect is a change in the albedo – the fraction of the incident sunlight that is reflected back to space.

Using Adi To Quantify A Color Change In Crayfish, Jennifer Welborn

STEM Digital

Do Crayfish Change Color If Their Environment Changes? A Guided Inquiry Lab for 7th grade Life Science

Background: There is anecdotal evidence from bass fisherman that crayfish are able to change color depending on their surroundings. A (cursory) literature review of this phenomenon showed that no formal research has been done in this area. Students had an additional informal lesson about research funding (or lack thereof) because of this finding.

Students designed and conducted a controlled experiment to see the effect of changing environment color on crayfish color.

ADI was used to quantify a color change.

Human Variation In Skin Color And Race As A Social Construct, Jennifer Welborn

STEM Digital

This lesson is part of evolution unit which follows heredity and genetics

The lesson is interdisciplinary in nature in that I discuss the concept of race as a social construct and the idea that there are “black, white, red, yellow” skinned people is something that people developed. It is not based on biology. Race groupings are human-made groups.

Students first learn about mixing light and how to determine black and white from an ADI analysis. They learn that red and green = yellow, etc.

They then photograph each other’s forearms and analyze the images using ADI.

We then discuss skin …
