Comparing Particulate Matter Exposures During Two Work Shifts In A Large University Dining Commons Kitchen, Shalom Emmanuel, Atin Adhikari

Journal of the Georgia Public Health Association

Objective: Cooking emits a huge concentration of indoor air pollutants, including particulate matter (PM). Exposure to PM can lead to long-term adverse respiratory effects among workers engaged in cooking. Only a few studies have measured cooking-related air pollutants in large school cafeterias where young student workers are frequently employed. The objective of this research was to compare stationary exposures to PM from cooking during two work shifts at a very large university dining commons kitchen.

Methods: Number concentrations of PM of varying aerodynamic sizes (1, 2.5, 5, and 10 µm) were measured at the back kitchen, DC grill, and …

For The Love Of Stories: Re-Examining Academia’S Responsibility In Presenting Literature In The 21st Century, April Trepagnier

Honors College Theses

Angus Fletcher, a neuroscientist who hung up his lab coat to earn a Ph.D. in literature from Yale, studies stories as, “a narrative-emotional technology that helped our ancestors cope with the psychological challenges posed by human biology...an invention for overcoming the doubt and the pain of just being us.” But students entering college are losing interest in this “technology.” A 2017 report by the American Academy of Arts and Science showed a “statistically significant decline” in the number of English graduates from 2011-2012 to 2016-2017. Peter Barry, Professor Emeritus of English at Aberystwyth University, may offer insight into this trend. …

Steam Gasification Of Biochar To Produce Hydrogen-Rich Syngas, Nnamdi Ofuani

Honors College Theses

A key greenhouse gas (GHG) emission contributing to climate change is carbon dioxide (CO₂) emission. This emission is largely due to the use of fossil fuel as a major energy source. Biomass is an alternative energy source. Biochar, a byproduct of the pyrolysis process (of biomass), could be gasified to produce syngas (a mixture of CO and H₂). This syngas can further be used to produce different kinds of fuels like biodiesel, bio-gasoline, bioethanol, etc. In the steam gasification of biochar, the quality and yield of syngas is dependent on parameters such as temperature, particle size, …

Achieving safely managed sanitation and resource recovery in areas that are rural, geographically challenged, or experiencing rapidly increasing population density may not be feasible with centralized facilities due to space requirements, site-specific concerns, and high costs of sewer installation. Nonsewered sanitation (NSS) systems have the potential to provide safely managed sanitation and achieve strict wastewater treatment standards. One such NSS treatment technology is the NEWgenerator, which includes an anaerobic membrane bioreactor (AnMBR), nutrient recovery via ion exchange, and electrochlorination. The system has been shown to achieve robust treatment of real waste for over 100 users, but the technology’s relative life …

Innovative Research For Phosphorus Recovery In Freshwater Sediments, An Experimental Framework, John D. Collins

Honors College Theses

Phosphorus, a finite element, is necessary for all living organisms and directly impacts biota growth as well as productivity in freshwaters. The demand for phosphorus is continually increasing, but the supply of phosphorus is continually decreasing. In response to depleting resources, phosphorus in surface water sediments is being explored as a sustainable solution to the forecasted phosphorus shortage. Phosphorus in sediments is generally bound to oxidized iron (Fe3+) forming iron phosphate complexes. This form of phosphorus is released when iron reduces to Fe2+ in anaerobic environments. Under such conditions, soluble phosphorus (i.e., orthophosphate) may then be recovered using compounds that …

A Proof-Of-Concept Study For An Elastohydrodynamic Seal Design, Cameron M. Stuart

Honors College Theses

Supercritical CO₂ (sCO₂) power cycles are superior to traditional water based, air-breathing, direct-fired, open Brayton cycles or indirect-fired, closed Rankine cycles in terms of efficiency and equipment size. They hold great potential in fossil fuel power plants, nuclear power production, solar power, geothermal power, and ship propulsion. To unlock the potential of sCO₂ power cycles, utilized technology must withstand 10–600 MWe and at sCO₂ temperatures and pressures of 350–700℃ and 20–35 MPa for nuclear industries. Amongst many challenges at the component level, the lack of suitable shaft seals for sCO₂ operating conditions needs to …

Drone Control Using Bci Technology, Jeremie Otniel Kamba Kalunga

Honors College Theses

A drone, also known as an unmanned aerial vehicle (UAV), is a type of aircraft that is operated remotely or autonomously. The utilization of drones increased because it is now possible to use them to perform tasks that would be too complicated for human beings to do. Electroencephalograms (EEG) are generated by the electrical activity of the brain and can be measured by placing electrodes on the scalp. The idea of controlling drones using EEG signals refers to the use of EEG technology to control the movement of a drone. EEG signals are used to determine the user's intention and …

Utilization Of Machine Learning To Investigate Material State, Ana B. Abadie

Honors College Theses

The ability to predict material behavior that undergoes various loading conditions is critical to the development of reliable and safe components. Thermal and mechanical fatigue loading can cause significant damage to materials, leading to failure and potential safety hazards. Machine learning algorithms have emerged as a promising tool for improving accuracy and efficiency of predicting material behavior under such loading conditions. This research provides a comprehensive overview of a machine learning algorithm that is able to analyze and predict material state independently of the loading sequence. Unidirectional carbon fiber reinforced polymer (UD CFRP) composite which has undergone two different loading …

Cycle Time Reduction In Additive Manufacturing Using Peltier Thermoelectric Cooling Devices, Trevor Carlton

Honors College Theses

Thermoelectric cooling and the Peltier effect were discovered in 1834, over 188 years ago. Additionally, the first iterations of additive manufacturing (i.e., 3D printing) began in the early 1980s, more than 40 years ago. Despite these technologies’ age and years of advancements, the application of Peltier cooling-based devices in additive manufacturing has not yet been realized. These devices can be used for the active thermal management of print beds in 3D printers. Developing a mechanism to heat and cool a print bed can reduce the cycle time to manufacture a part. In 3D printing, waiting for the heated bed to …

On Cox Proportional Hazards Model Performance Under Different Sampling Schemes, Hani Samawi, Lili Yu, Jingjing Yin

Biostatistics, Epidemiology & Environmental Health Sciences: Faculty Publications

Cox’s proportional hazards model (PH) is an acceptable model for survival data analysis. This work investigates PH models’ performance under different efficient sampling schemes for analyzing time to event data (survival data). We will compare a modified Extreme, and Double Extreme Ranked Set Sampling (ERSS, and DERSS) schemes with a simple random sampling scheme. Observations are assumed to be selected based on an easy-to-evaluate baseline available variable associated with the survival time. Through intensive simulations, we show that these modified approaches (ERSS and DERSS) provide more powerful testing procedures and more efficient estimates of hazard ratio than those based on …

Optimization Of A Simultaneous Localization And Mapping (Slam) System For An Autonomous Vehicle Using A 2-Dimensional Light Detection And Ranging Sensor (Lidar) By Sensor Fusion, Shaen Mehrzed

Honors College Theses

Fully autonomous vehicles must accurately estimate the extent of their environment as well as their relative location in their environment. A popular approach to organizing such information is creating a map of a given physical environment and defining a point in this map representing the vehicle’s location. Simultaneous Mapping and Localization (SLAM) is a computing algorithm that takes inputs from a Light Detection and Ranging (LiDAR) sensor to construct a map of the vehicle’s physical environment and determine its respective location in this map based on feature recognition simultaneously. Two fundamental requirements allow an accurate SLAM method: one being accurate …
