Rubber-modified asphalt pavements have been used in Sweden and the United States since the 1970's. In these applications ground recycled tire particles (0.25 inch minus) are added to a gap-graded aggregate and then mixed with hot asphalt cement. The benefits of adding rubber to the mix include increased skid resistance...
The purpose of this study was to provide the USDA-Forest Service,
Bureau of Land Management (BLM), and other agencies or industries
that may deal with temporary and intermittent use roads with
the necessary background information for the identification, economic
evaluation, and selection of the alternate surfacing systems and to
determine...
The bioavailability of vitamin B-6 from four selected
foods was investigated in five men, aged 22 to 25 years,
who were receiving a pyridoxine supplement. The subjects
received a constant diet containing 1.34 mg of vitamin B-6
throughout this five-week study, except on Saturdays and
Sundays when they ate their...
The corrosion and passivity of iron (and carbon steel) in media with different alkalinity as well as iron depassivation have been studied extensively using electrochemical methods and nano-scale surface characterization studies. The electrochemical techniques provide valuable information about the average electrochemical behavior of relatively large metal surfaces, typically in centimeter-square...
Portable, high power efficiency communication devices is a growing market in the semiconductor industry. Analog-to-digital converters (ADC) are key interface that are used to digitize the sensed information. Recently, digital techniques have been proposed to improve analog building block power efficiency in sub-micron technologies. This research focuses on mixed signal...
In order to enable better visualization and understanding of the effect of the robot's geometry and inertia on the robot's trajectories, this dissertation proposes to use geometric mechanics to bridge the gap between the physical motion of a robot and its mathematical structure. The main focus of this research is...
A new modular loop architecture for distributed computer
systems has been developed and compared with three of the most
prominent loop architectures currently being used. The competitive
loops with which the new architecture has been compared
are the Newhall loop, the Pierce loop and the DLCN loop. The four
loop...
This study focuses on investigation of the RETRAN modeling
concepts in the analysis of a safety valve discharge transient.
Three safety valve tests conducted at the Combustion Engineering
test facility were chosen for evaluation with RETRAN. It was
essential to apply the critical flow boundary condition at the
downstream nodes...
