Amorphous metal thin films lack the grain boundaries and dislocations present in
crystalline metal films. As a result, amorphous metal films can be more mechanically robust, atomically smooth, and more resistant to chemical attack than crystalline metals. However, amorphous metals are meta-stable and subject to crystallization upon heating, thus limiting...
This paper presents a production study of a modified hydraulic excavator used for yarding and loading logs. The machine utilized in this study is a Caterpillar 245. Approximately 3067 cunits (4053 pieces) of old growth Douglas fir were logged from a 29 acre setting in the Coast Range of southwestern...
This report summarizes the outcomes of a March 22-25, 2010, workshop in Seattle, Washington, on the environmental effects of tidal energy development. The workshop focused on building capabilities to evaluate the environmental effects of tidal energy from turbines placed in the water column throughout the United States. However, it did...
A reduced-order dynamic model is derived that captures the primary dynamics of a jet-in-crossflow. This is significant progress toward the end goal of reduced order model based closed-loop flow control. The reduced order model is a set of differential equations obtained through the use of snapshot based Proper Orthogonal Decomposition...
The problem considered is that of causing all the machines of an
array to turn on simultaneously in the least amount of time. Each
machine is a finite sequential machine that can communicate with a
limited number of prescribed neighbor machines.
A solution for a linear array of these machines,...
Despite advances in the understanding of rain-on-snow storms and their resulting peak flows, little is understood about the response of snowmelt to precipitation and the relative timing of the two at multiple temporal scales within such events. To address this issue, climate, snowmelt, and streamflow data were analyzed for 26...
This paper discusses the development of a computer simulation program for the operation of a log landing for the proposed Helistat airship. The first part of the paper describes the time study used to develop production rates for the chasers, buckers, front-end loaders, and skidders to be used on the...
Two approaches to improving wood treatability include the modification of pressure
schedules during conventional liquid treatments and the use of supercritical fluids (SCFs). In
both of these techniques, pressure differences are important for transporting materials into
wood. The level of pressure and its change during SCF treatments are also important...
Forest ecosystems are the most important terrestrial carbon (C) storage globally, and presently mitigate anthropogenic climate change by acting as a large and persistent sink for atmospheric CO₂. Yet, forest C density varies greatly in space, both globally and at stand and landscape levels. Understanding the multi-scale drivers of this...
Acute phase protein (APP) measurement can be used to characterize and rapidly detect inflammation. Serum amyloid A (SAA) and haptoglobin (HP) may be useful for diagnostic and prognostic purposes in horses presenting for colic and other inflammatory diseases. The objective of this thesis was to evaluate the use of SAA...
