Optimizing the superlens: manipulating geometry to enhance the resolution

Creator:: Podolskiy, Viktor A., Kuhta, Nicholas A., and Milton, Graeme W.
Abstract:: We analyze the performance of a planar lens based on realistic negative index material in a generalized geometry. We demonstrate that the conventional superlens design (where the lens is centered between the object and the image) is not optimal from the resolution point of view, develop an analytical expression for...

Correct abstraction in counter-planning : a knowledge compilation approach

Creator:: Flann, Nicholas S.
Abstract:: Knowledge compilation improves search-intensive problem-solvers that are easily specified but inefficient. One promising approach improves efficiency by constructing a database of problem-instance/best-action pairs that replace problem-solving search with efficient lookup. The database is constructed by reverse enumeration- expanding the complete search space backwards, from the terminal problem instances. This approach...

Abstract:: As people encroach increasingly on natural areas, one question is how this affects avian biodiversity. The answer to this is partly scale-dependent. At broad scales, human populations and biodiversity concentrate in the same areas and are positively associated, but at local scales people and biodiversity are negatively associated with biodiversity....

Prediction of Wood Fiber Attributes from LiDAR-Derived Forest Canopy Indicators

Creator:: Hilker, Thomas, Frazer, Gordon W., Coops, Nicholas C., Wulder, Michael A., Newnham, Glenn J., Stewart, James D., van Leeuwen, Martin, and Culvenor, Darius S.
Abstract:: We investigated the potential use of airborne light detection and ranging (LiDAR) data to predict key wood fiber properties from extrinsic indicators in lodgepole pine leading forest stands located in the foothills of central Alberta, Canada. Six wood fiber attributes (wood density, cell perimeter, cell coarseness, mature fiber length, microfibril...

Beached birds and physical forcing in the California Current System

Creator:: Parrish, Julia K., Bond, Nicholas, Nevins, Hannah, Mantua, Nathan, Loeffel, Robert, Peterson, William T., and Harvey, James T.
Abstract:: Seabirds have often been proposed as environmental indicators. Beached bird data may provide an additional data source and such data is efficacious because it can reliably be collected by volunteers. In addition to anthropogenic factors, such as oil spills, changes in the ocean-atmosphere can affect carcass beaching rate in 3...

Instrumenting Wildlife Water Developments to Collect Hydrometeorological Data in Remote Western U.S. Catchments

Creator:: Grant, Nicholas, Saito, Laurel, Weltz, Mark, Walker, Mark, Daly, Christopher, Stewart, Kelley, and Morris, Christo
Abstract:: In the arid western United States, wildlife water developments, or ‘‘guzzlers,’’ are important water sources for wildlife, and consist of impermeable roof structures designed to intercept precipitation and small tanks for storing water. Guzzlers are typically installed in remote mid- to high-elevation basins, where precipitation data are often scarce. In...

Abstract:: Dendritic ecological networks (DENs) are a unique form of ecological networks that exhibit a dendritic network topology (e.g. stream and cave networks or plant architecture). DENs have a dual spatial representation; as points within the network and as points in geographical space. Consequently, some analytical methods used to quantify relationships...
