Use of a probabilistic neural network to reduce costs of selecting construction rock
Donald A. Singer, James D. Bliss
2003, Natural Resources Research (12) 135-140
Rocks used as construction aggregate in temperate climates deteriorate to differing degrees because of repeated freezing and thawing. The magnitude of the deterioration depends on the rock's properties. Aggregate, including crushed carbonate rock, is required to have minimum geotechnical qualities before it can be used in asphalt and concrete. In...
Uncertainty in spatially explicit animal dispersal models
Wolf M. Mooij, Donald L. DeAngelis
2003, Ecological Applications (13) 794-805
Uncertainty in estimates of survival of dispersing animals is a vexing difficulty in conservation biology. The current notion is that this uncertainty decreases the usefulness of spatially explicit population models in particular. We examined this problem by comparing dispersal models of three levels of complexity: (1) an event-based binomial model...

Java Programs for Using Newmark's Method and Simplified Decoupled Analysis to Model Slope Performance During Earthquakes
Randall W. Jibson, Matthew W. Jibson
2003, Open-File Report 2003-5
Landslides typically cause a large proportion of earthquake damage, and the ability to predict slope performance during earthquakes is important for many types of seismic-hazard analysis and for the design of engineered slopes. Newmark's method for modeling a landslide as a rigid-plastic block sliding on an inclined plane provides a...
