Purdue Air Sense: A Methodology For Improving The Accuracy Of Ambient Aerosol Mass Concentration And Size Distribution Measurement With Low-Cost Optical Sensing Techniques, Rishabh Ramsisaria, Satya Sundar Patra, Brandon Emil Boor

The Summer Undergraduate Research Fellowship (SURF) Symposium

There is a global lack of a means for monitoring air pollutant levels at a local level due to expensive and bulky instrument requirements. It is important to monitor toxic gas levels, as well as particulate matter levels, in the atmosphere to study their effects on human health and to further develop city- and community-level air pollution solutions. In this study, with the means of a Raspberry Pi, low-cost Alphasense Optical Particle Counter and gas sensors, and methodical calibration techniques, we built a portable 3-D printed module powered by clean electricity generated by an on-board Voltaic solar cell that measures …

Indoor Premise Plumbing: The Relationship Between Water Stagnation, Chlorine Decay, And Total Organic Carbon Levels, Emerson M. Ringger, Andrew J. Whelton, Tolulope Odimayomi, Maryam Salehi

The Summer Undergraduate Research Fellowship (SURF) Symposium

Drinking water safety is critical to the health of populations worldwide, and modern plumbing infrastructure can influence drinking water chemical characteristics. Inside residential and commercial buildings however, water use and contact with different plumbing components can vary. For example, water can endure lengthy stagnation periods and residual disinfectant agents like chlorine can decay, leaving the water vulnerable to microbial growth. Plastic cross-linked polyethylene (PEX) pipes have become popular and have shown to influence water quality. While several studies have been carried out on chemical leaching from PEX piping, none were found that examined the role of pipe diameter in relation …

My Catalyst, Gabrielle Gambino Lyon

Celebration of Learning

Over the course of my internship and shadow program with Pepper Lawson Construction and Ziegler Cooper Architects, I was able to explore the various career paths involved in the design, construction, and civil engineering fields. My work on the construction site of a high-rise apartment building located in the heart of Houston, TX allowed me first-hand experience working and learning alongside project engineers, contractors, building developers, and the construction team.

This project was the perfect confluence of my main areas of interest: structural, mechanical, civil, and environmental engineering, as well as architecture. My daily work consisted of on-site walk throughs, …

Introduction To Infrastructure - The Influence Of Natural Disasters On Infrastructure, Tri Tam Nguyen, Sean M. Raday, Daniel Leverick

STEM Student Research Symposium Posters

In this paper, three major hurricanes in 2017 were examined to determine the damage these hurricanes have done to the infrastructure. Infrastructure has an important role in the nation’s sustained economic development. Infrastructure consists of two main types which are “hard” infrastructure and “soft” infrastructure. Hard infrastructure is the physical networks which include transportation, power, etc. while soft infrastructure is institutions and human capital. Inadequate and inefficient performance of “hard” or “soft” infrastructure would prevent economy from achieving full growth. In the past decades, a significant increase in the number of natural disasters has had great impact on infrastructure systems. …
