Streamflow patterns are a result of the interaction of many factors, including climate, vegetation, geology, and topography. Analyses indicate that streamflow patterns have changed around the United States over the past century, raising questions about the possible role of climate variability as a driver of water yield. This thesis examines...
This work introduces a new methodology to design transportation fuels offering improved efficiency and reduced emissions, aimed to complement both traditional and emerging engine technologies. Many of these emerging technologies are centered around exploiting low temperature combustion (LTC) strategies that offer improved efficiency and reduced emissions. However, a standardized fuel...
A microchannel-based hemodialyzer offers a novel approach to hemodialysis practice and holds many promises for improving dialysis treatment efficiency and quality of life for kidney patients. The hollow fiber hemodialyzer, a conventional dialysis device, has certain limitations including non-uniformity of the dialysate flow path which necessitates the use of a...
In many regions of the world, a significant portion of the surface water originates in mountain headwaters where the timing and magnitude of streamflow is largely dictated by the seasonal storage of precipitation as snowpack and long-term storage as glaciers. Accumulation, persistence, and melt of snow and ice are functions...
The intent of this report is to provide a brief description of water quality issues in Nicaragua, Uganda and Bangladesh, and the technologies available to address these issues. The water quality parameters considered include: bacterial contamination, heavy metals and arsenic, pesticides and industrious chemicals, turbidity, radiological characteristics, and taste and...
The potential of red blood cell (RBC) and platelet damage was studied for a novel microfluidic hemoperfusion device currently in development at Oregon State University for use in treating sepsis. COMSOL 4.4's computational fluid dynamics (CFD) module was used to examine shear rate profiles in laminar, Newtonian blood flow throughout...
This thesis presents and discusses a method for comparing
the neutron flux of some calculational model with the actual
flux of a critical system. Both the theoretical and experimental
aspects of this method are investigated in this report.
Experiments were performed to find neutron energy dependent
data. These involved the...
The noise problem in air conditioning systems is receiving ever
increasing attention because of the importance of noise on a comfortable
human environment. Some work has been done on the solutions
to the noise problem by an investigation of a few system elements.
The acourstical characteristics of dampers become more...
The repetitious nature of air conditioning calculation leads to
arithmetic errors and a high cost of designing air conditioning systems.
Short cut calculations are employed to limit the calculation
and the chance of making errors.
Computers with their high speed of calculation and the ability
to make limited "logic's decisions...
