Comparative investigations based on volcanic morphology suffer from the lack of a large terrestrial baseline for comparison. To fill this gap, the Lava Flow Morphology Database (LAMDA) was proposed as a GIS based central clearinghouse for remote and field investigations of volcanic morphology. This study presents an analysis of LAMDA’S...
For building robust software applications, it is important for the software engineer to make efficient use of the available building blocks. Learning the basic language constructs is only the first step in this process. It is becoming increasingly important for software engineers, especially students, to get acquainted with the available...
Dimensionality reduction (DR) is an efficient approach to reduce the size of
data by capturing the informative intrinsic features and discarding the noise. DR
methods can be grouped through a variety of categories, e.g. supervised/ unsupervised,
linear/non-linear or parametric/non-parametric. Objective function based
methods can be grouped into convex and non...
Beaversource provides both code-hosting tools and social networking in one place. Students and faculty at Oregon State University have been using Beaversource to host their projects, both for classwork and research. Several usability problems were reported in a survey conducted on Beaversource last year. Some of these issues were severe...
Declines or extinctions of the native intertidal estuary blue mud shrimp, Upogebia pugettensis, have been observed or are suspected in all of its populations over the species’ range. These declines are associated with the introduced Asian bopyrid isopod parasite, Orthione griffenis, which effectively castrates females. Baseline estimates of population abundances...
Application Programming Interfaces (APIs) enable software developers to utilize and create functionality that would otherwise take a lot of time and effort to build from scratch. Consequently, an essential part of software engineering training is for students to learn how to use APIs effectively. The existing jTutors system enables an...
This project addresses the problems of manually placing facial landmarks on a portrait and finding a fast way to warp the annotated image of a face. While there are many approaches to automatically find facial landmarks, most of them provide insufficient results in uncontrolled environments. Thus I introduce a method...
This project presents a new, and more versatile, method for performing Relief Mapping (also known as Parallax Occlusion Mapping), utilizing rates of change in texture coordinates across a polygon surface to calculate the texture sampling offsets used in the ray-tracing portion of the Relief Mapping algorithm. This new technique relies...
American Indians presently face health risks posed by exposure to environmental pollutants through different exposure routes including: inhalation (e.g., air particles), ingestion (e.g., fish, water), and dermal contact (e.g., contact with water, soil). Geographic Information Systems (GIS) are increasingly being used in the Environmental Health arena as a tool for...
The seafood industry in Alaska produces about 4.4 billion pounds of fish every year and approximately 2.2 billion pounds of fish waste. Product recovery rates in the seafood industry have increased in the last decade, but still a large portion of all harvested fish is unused and often discharged into...
