A techno-economic analysis (TEA) was performed to evaluate the technology, cost, and resource use for algal biofuel production based on today’s economics and technology. The basic goal of this study is to develop a model to calculate the mass and energy balances and costs to produce 10 million gal of...
Automation of Capacitor Discharge Welding (CDW) has not been investigated in
industry due to the limited understanding of the process. The US Department of Energy's Albany Research Center (ALRC) has done an extensive study of the process and reported applications of welds in the manufacture of electro-mechanical products such as...
Across the U.S. social activism is on the upsurge, offering possibilities for a revolution against capitalism. However, these possibilities are potentially undermined by entrenched factionalism amongst the left. At root, such in-fighting is fostered by the creation of false dualistic frameworks on the transition out of capitalism and into the...
The “fat-hunger paradox” is a relatively recent phenomenon in the United States in which people of low socioeconomic status are disproportionately overweight or obese, and yet frequently lack access to adequate food and nutrition. Research indicates additional disparities in the prevalence of overweight and obesity amongst most racial and ethnic...
Small and medium-sized enterprises that are characterized by high-mix, low-volume, and highly variable production operations often have unstructured material movement processes that are prone to material handling wastes. These sub-optimal material handling systems are oftentimes a result of small and medium-sized enterprise's limited resources. Current tools to assist organizations in...
This thesis consists of three studies to better understand the environmental sustainability potential for algal-based biofuels. Initially, a comparison of recent life cycle assessments (LCA) of theoretical full-scale algal biofuel facilities was developed. These studies include varying boundaries and scope, functional units, and technology maturity assumptions. The comparison converted results...
Hydrogen has been shown to be a promising replacement for fossil fuels for use in light duty vehicles because it is a clean, renewable and plentiful resource with a high gravimetric energy density. However, in order to obtain an acceptable volumetric energy density, densification of the hydrogen is required. Adsorptive...
Strong tidal currents experienced at Keystone Harbor, WA, have caused navigational hazards and disrupted ferry service in the area. This thesis presents details of the design, construction and implementation of a large scale physical model of Keystone Harbor used to evaluate the effectiveness of proposed jetty design alternatives to improve...
Hydrogel polymers are a novel class of hydrophilic materials that have large application areas in both the industrial and medical fields. Carboxymethyl cellulose (CMC) has received attention as a hydrogel polymer. Methods to modify the mechanical properties of gels and films made from CMC are of interest in our lab...
This research focused on the enhanced reductive dechlorination of trichloroethene (TCE) and its surrogate, trichlorofluoroethene (TCFE), using two bioremediation methods in anaerobic conditions. Two anaerobic bioremediation studies were conducted to investigate the effects of microbial communities in the presence of different electron acceptors and donors during anaerobic reductive dechlorination of...
