Cation Exchange In Glacial Till Subjected To Highway Deicing Agent Infiltration, Niki Kallergis

Environmental & Water Resources Engineering Masters Projects

The site studied in this research project is owned by the Massachusetts Highway Department and has been used as a storage facility since the 1960's. The area has been characterized as a drumlin of glacial till composition. Improper storage practices occulTed during two decades (1960's - 1980's) by stockpiling deicing agents outdoors. Previous investigations verify groundwater contamination due to brine infiltration and establish several properties of the soil and the aquifer hydraulics. The chloride ion is unreactive and transported with groundwater molecules; however, field data and theory suggest that dissolved sodium partakes in cation exchange with sorbed cations on clay …

The Use Of Numerical Modeling Techniques To Optimize Groundwater Withdrawls And Minimize Streamflow Depletion, Yamen Hoque

Environmental & Water Resources Engineering Masters Projects

Groundwater reserves can be a valuable resource in alleviating rising water demands worldwide. The groundwater is generally pumped out of surficial aquifers using withdrawal wells. However, unregulated groundwater withdrawals can impact the flow in nearby streams negatively, causing streamflow depletions. This can hinder the ecological balance of streams and endanger the aquatic life fonTIs that call such streams home. Therefore, groundwater withdrawals must be carried out using a well managed withdrawal strategy. Rhode Island has a growing annual water demand that has been projected to exceed current supply in parts of the state by 2020. As a result, several new …

Evaluation Of Nutrients Along The Blackstone River, Megan M. Patterson

Environmental & Water Resources Engineering Masters Projects

The University of Massachusetts Blackstone River Water Quality Study was conducted in August of 2005 through November of 2006. Water quality was monitored throughout two dry weather events and five wet weather events along the Blackstone at over 20 sites from the headwaters downstream to Woonsocket, Rhode Island. Special emphasis was placed on the analysis of the nutrient loadings crossing the Massachusetts/Rhode Island state border. Continuous nitrate and phosphate readings were collected at the state line using MicroLABs. The MicroLAB results required a high degree of data adjustment; duplicate samples are recommended to ensure future data quality. Data from events …

Treatment Of Domestic Wastewater Using An Anaerobic Membrane Bioreactor: Performance And Characterization, Joseph C. Fermanian

Environmental & Water Resources Engineering Masters Projects

Anaerobic wastewater treatment has many advantages over aerobic treatment, however, factors that limit its application are the relatively high concentration of soluble organic matter in the effluent and poor settling characteristics of anaerobic sludge. Membrane filtration provides exceptional solids removal and biomass retention that can improve the biological treatment process as has been seen with aerobic MBR. The application of anaerobic processes and anaerobic membrane bioreactors (AnMBR) has been limited primarily to industrial wastewaters. The use of AnMBR in treating domestic wastewater is of great interest; however, it has not been studied sufficiently to implement on a large scale commercial …

Evaluation And Optimization Of A Pcr Assay And Multiple Regression Model For The Detection Of Rhodococcus Corprophilus, Stephen Clark

Environmental & Water Resources Engineering Masters Projects

Rhodococcus coprophilus is an emerging tool in the microbial source tracking "tool-box". The actinomycete is a source specific indicator for grazing animal fecal contamination. Once thought of as less harmful to human health, concern over animal fecal contamination has increased with the greater understanding of zoonoses. Zoonotic organisms that have the ability to cause disease in both humans and animals. Major outbreaks from these pathogens have increased their awareness and created a need for better source water protection. The presence of Rhodococcus coprophilus has been shown to have the ability to indicate grazing animal fecal contamination but it's current detection …

Investigation Of Contact Pressure Distribution On Sheet Metal Stamping Tooling Interfaces: Surface Modeling, Simulations, And Experriments, Sripati Sah

Masters Theses 1911 - February 2014

In stamping operations, sheet metal is formed into a desired shape by pressing it in a hydraulic or mechanical press between suitably shaped dies. As a predominant manufacturing process, sheet metal forming has been widely used for the production of automobiles, aircraft, home appliances, beverage cans and many other industrial and commercial products. A major effort till date on stamping processes monitoring has been focused on investigating variations in the press force. Given that the press force itself is an integral of the contact pressure distribution over the die and binder contact interfaces, it is conceivable that defects may be …

Over the past decades, there have been worldwide efforts to synthesize new types of ordered porous materials for catalysis, separations, etc. Among those, mesoporous material with microporous walls are promising in a sense that while mesopores act as channels for the reactant transport with little diffusion limitation, micropores in the wall act as active sites for reactions or storage of the molecules. In this study, we focused on the SBA-15 material, which is a highly ordered mesoporous silica material with micropores present in the wall. We have studied the synthesis of the material by manipulating various factors that are known …

Power Amplifier Linearization Implementation Using A Field Programmable Gate Array, Abilash Menon

Masters Theses 1911 - February 2014

The emphasis on higher data rates, spectral efficiency and cost reduction has driven the field towards linear modulation techniques such as quadrature phase shift keying (QPSK), quadrature amplitude modulation (QAM), wideband code division multiple access (WCDMA), and orthogonal frequency division multiplexing (OFDM). The result is a complex signal with a non-constant envelope and a high peak-to-average power ratio. This characteristic makes these signals particularly sensitive to the intrinsic nonlinearity of the RF power amplifier (PA) in the transmitter. The nonlinearity will generate intermodulation (IMD) components, also referred to as out-of-band emission or spectral re-growth, which interfere with adjacent channels. Such …
