The Summer Undergraduate Research Fellowship (SURF) Symposium

Tokamaks for fusion research are extremely complex and are still limited by inherent instabilities such as material erosion from plasma instabilities. Due to the lack of data and high demand of resources, simulations to portray Tokamaks are essential. A Particle-In-Cell (PIC) simulation for plasma erosion on materials within the Tokamak is to be benchmarked using the experimental data obtained in these experiments. The effects of an axial magnetic field (magnetic field lines are along the plasma propagation direction) on an expanding laser produced plasma plume are investigated. A Continuum Surelite Nd:YAG laser system at 1064 nm wavelength and 6 ns …

JTRP Technical Reports

An empirical model called the Traffic Air Quality Model (TAQ) was developed from meteorological and PM2.5 measurements adjacent to the Borman Expressway in Northwest Indiana to estimate PM2.5 road emissions. It concluded that on average a 74% improvement in air quality is expected (based on reduction of mass emitted per mile [g/mi]) when the average Borman speed range is improved from < 30 mph to >50 mph. An additional 39% (on average) improvement in the PM_2.5 emissions on the Borman Expressway was found when traffic flow speeds increased from 55 mi/h to 75 mi/h. The TAQ model was found to perform well when tested …

JTRP Technical Reports

This study is a continuation and the final phase of the SPR-2338 project that involves monitoring the ambient air quality levels adjacent to the Borman Expressway. The purpose of this phase was to classify the traffic conditions along the Borman Expressway in terms of ambient air quality levels. The duration of the phase was from April 1, 2002 to April 30, 2004. The study has shown that, in a close proximity to the Borman Expressway, air quality levels mirror the dynamic nature of traffic along the Borman, despite being surrounded by major industrial stationary sources. Therefore, a descriptive model was …

JTRP Technical Reports

Particulate Matter less than 2.5 μm in diameter (PM2.5), carbon monoxide (CO), and meteorological parameters were monitored at 10 second averaging intervals adjacent the Borman Expressway in Northwestern Indiana before and during the implementation of an Intelligent Transportation System. Traffic data was collected from sensors on the expressway. The high-resolution data permitted the expressway contribution to local air quality to be separated from background components of local air quality and significant correlations were made between pollutant flux and traffic flow and pollutant flux and highway occupancy. Traffic incidents (accidents / congestion) were shown to have a rapid impact on local …
