Logic Sampling, Likelihood Weighting and AIS-BN are three variants of stochastic sampling, one class of approximate inference for Bayesian networks. We summarize the ideas underlying each algorithm and the relationship among them. The results from a set of empirical experiments comparing Logic Sampling, Likelihood Weighting and AIS-BN are presented. We...
In the context of forest products, a cutting order is a list of dimension parts along with demanded quantities. The cutting-order problem is to minimize the total cost of filling the cutting order from a given lumber grade (or grades). Lumber of a given grade is supplied to the production...
As ocean ecosystems continue to deteriorate in the face of human induced pressures, marine management professionals are increasingly being urged to predict the impacts of various activities on ocean ecosystems. Many ecosystem interactions are still not adequately understood, so managers often turn to scientists to provide data and analysis on...
Geospatial data analysis is a multifaceted discipline encompassing the collection, processing, and visualization of diverse datasets. It models and delineates the interactions of people, objects, and phenomena within geographical spaces and predicts patterns based on the relationships between different locations. Despite significant advancements in geospatial data engineering and analytics over...
Three library faculty at Oregon State University (OSU), a research intensive university, created the Data Sharing Wizard (the Wizard), a Scenario-Based, online, interactive learning tool that helps students learn about the sharing of research datasets with a focus on intellectual property and decision making. Using the Wizard, students are able...
Sequence alignments, phylogenetic trees, and associated information for Phylogenetic Estimation and Ancestral State Reconstruction of Rubus (Rosaceae) using Target Capture Sequencing
A flipped classroom provides students with course content in the form of videos, readings, and/or simulations that they complete during the time traditionally used for homework assignments while in-class time is devoted to hands-on group learning activities. Project BoxSand is gathering quantitative data on how students in a flipped classroom,...
A sampling criterion which provides a numerical relationship
between sampling rate and worst-case peak error for linear interpolation
of sample points is presented. The criterion, based upon the
second derivative of a waveform, is derived, its properties are observed
for a sine wave, and its applicability to complex signals is...
It is necessary to evaluate and compare the characteristics of
various methods of accessing data-files in order to utilize economically
both the hardware and the software (Space and Time) supported
by the digital on-line system. The purpose of this paper is to
describe and evaluate the structure and use of...
An advanced laboratory interfacing capability was developed
for the Real-Time Digital Computer Laboratory in the Chemical
Engineering Department. A stationary interfacing unit located
beside the computer mainframe and two small remote units were
designed, developed and thoroughly tested. These interfacing
units permit experiments with a wide variety of analog and...
