This thesis examines forest history of a portion of the Douglas-fir Region: Soap Creek Valley, a 15,000 acre sub-basin of the Luckiamute River in northern Benton County, Oregon. The primary reasons for the research were to test oral history methodology, document sub-basin scale forest cover pattern changes, and determine basic...
Crops were grown at the experimental farms using accepted cultural practices (within the limits of experimentation) or trials were conducted on growers' fields. Most experiments were designed as randomized complete blocks with three to five replications. Herbicide treatments were applied uniformly with precision plot sprayers. Unless otherwise indicated, preplant herbicide...
Many performance tuning tools for parallel software use visual representations of trace data to guide a developer towards code improvements. Most widely used visualization schemes, however, either omit useful information about time dependence of processor use, or include that information but do not scale well to long run times or...

Little Smalltalk is a small, reasonably fast, easy-to-understand, easy-to-modify Smalltalk system. The system was originally developed in 1984 as a part of an implementation project to develop a minimal Smalltalk system, closely resembling Smalltalk-80. The system was developed in C. The current project is an experiment to port the Little...

As part of the Willamette Basin Geographic Initiative Program, the Environmental Protection Agency (EPA) funded The Nature Conservancy of Oregon to inventory, classify, and map native wetland and riparian plant communities and their threatened biota in the Willamette Valley. Between October 1994 and September 1996, we evaluated 172 wetland and...
Data structures are essential for any programming task. Most of modem programming languages have a library of reusable data structures. In this project, Smalltalk-like collection classes have been implemented as a Java package. This package, collections, contains several useful data structures such as binary tree, B-Tree, bag, list, hash table...
The conventional way of debugging is to examine the program's state at various points during execution. With the addition of message passing as a means of communication and synchronization in message passing programs, the state of pending message operations also needs to be examined. Current parallel debuggers or analysis tools...
Various ecological and hydrological models require estimates of the amount and spatial distribution of monthly and annual precipitation. PRISM is an analytical model that distributes point measurements of monthly, seasonal and annual precipitation to a geographic grid. In order to use this model effectively, good graphical user interfaces were needed....

We have investigated a second-order phase transition of the vortex lattice in thin-film Nd₁.₈₅Ce₀.₁₅CuO[subscript 4-y] from 1 mT to 1 T applied magnetic fields. The dc resistivity-current density data for each field exhibit critical scaling consistent with a second-order vortex-liquid to vortex-solid phase transition. The high-field data support the vortex-glass...
Fires set by Native Americans were important in shaping and maintaining Willamette Valley prairie plant communities. With fire exclusion after Euro-American settlement in the 1840's, composition of the remaining prairies shifted toward shrub and tree dominance with a concomitant decline in endemic prairie plant populations. I hypothesize that by restoring...
