Jellyfish benefit from many of the changes mankind is making to the ocean. Climate change, overfishing, nutrient runoff, the introduction of invasive species, and coastal development all promote these ancient, gelatinous creatures. Because of their familiarity to readers and affinity for degraded places in the ocean, jellyfish are used to...
Data from the southern Cascade Mountains of
Oregon has been collected for application in computer
analysis of snowfields. Vegetation type, canopy
cover, slope, aspect, insolation, and snowfield
ground truth delineation are given consideration.
In addition, a procedure for transferral of data
onto Landsat imagery was derived.
Maintaining variation in software is a difficult problem that poses serious challenges for the understanding and editing of software artifacts. Although the C preprocessor (CPP) is often the default tool used to introduce variability to software, because of its simplicity and flexibility, it is infamous for its obtrusive syntax and...
ArcView 3D Analyst is a powerful geospatial tool, and has proven very useful in
3D visualization and analysis. In most cases, 3D data models are temporally static,
representing only one instance in time. For many applications, the 'missing' time
dimension is of great significance, and there is a need to...
Advanced computer architectures are centered around the parallel computer systems. This project is focused on the experiment on two parallel computer architectures : Sequent Balance 21000 shared memory multiprocessor and Cogent XTM distributed system.
A set of benchmark programs are implemented using "C" language and Dynix parallel programming library on...
A project is described wherein a source code browser was implemented based upon tasks performed by software engineers looking for source code modules with only UNIX utilities. These tasks were discovered by observing the actions of software engineers looking for code modules in a library, The success of the implementation...
With sequential computing technology reaching its speed limits, parallel processing is emerging as the key to very-high-speed computation. However, developing a parallel program is by no means a simple task; neither is analyzing the performance of parallel programs.
C* is a high-level data-parallel language that hides explicit message passing and...
Stream channel stability for two tributaries of Rock Creek in the
Oregon Coast Range is evaluated by application of a Stream Reach Inventory.
Stability nomographs are constructed for graphical analysis of
erosion potential. Results indicate that channel stability can be
classified. One stream is rated as 'Poor' in resistance to...
The needs and markets for aerial photography have grown
steadily with the increasing demands for improved resource
management (Kodak, 1985, 2 & Simonett, 1983, 1). Aerial
photography within the Willamette Valley could provide researchers
and professionals with a broad range of data in disciplines such as
agriculture, forestry, geology, and...
"Collaborative filtering algorithms’ performances have been evaluated using a variety of metrics.
These metrics, such as Mean Absolute Error and Precision, have often ignored recommendations for
which they do not have data. Ignoring these recommendations has provided numbers which do not
accurately represent the user experience. Qualitatively we have seen...
