Optimization Of Acid Production In Food Waste Via Anaerobic Respiration, Charles Daniels, Raymond Red Corn, Abigail S. Engelberth Phd.
Optimization Of Acid Production In Food Waste Via Anaerobic Respiration, Charles Daniels, Raymond Red Corn, Abigail S. Engelberth Phd.
The Summer Undergraduate Research Fellowship (SURF) Symposium
According to the Food and Agriculture Organization of the United Nations, one third of all food produced in world is wasted; 1.63 * 109 metric tons of nutrition is lost to transportation, contamination, or neglect every year (FAO 2013). This wasted food, however, could be repurposed as a substrate for microbial conversion into useful chemicals. This research is aimed at finding the optimal conditions for bacterial colonies to generate volatile fatty acids (VFAs): resources that are used as solvents, medicines, and chemical intermediates usually generated from petroleum based resources (Drumright et al., 2000) (Roscher 2000) (Kolt et al., 2007). …
Modeling Preventive Maintenance In Complex Systems, Jessica Rivas
Modeling Preventive Maintenance In Complex Systems, Jessica Rivas
Open Access Theses
This thesis presents an explicit consideration of the impacts of modeling decisions on the resulting maintenance planning. Incomplete data is common in maintenance planning, but is rarely considered explicitly. Robust optimization aims to minimize the impact of uncertainty--here, in contrast, I show how its impact can be explicitly quantified. Doing so allows decision makers to determine whether it is worthwhile to invest in reducing uncertainty about the system or the effect of maintenance. The thesis consists of two parts. Part I uses a case study to show how incomplete data arises and how the data can be used to derive …
