Empirical verification of fine-motoion planning theories

Description: Successful robot systems must employ actions that are robust in the face of task uncertainty. Toward this end, Lozano-Perez, Mason, and Taylor developed a model of manipulation tasks that explicitly considers task uncertainty. In this paper we study the utility of this model applied to real-world tasks. We report the results of two experiments that highlight the strengths and weaknesses of the LMT approach. The first experiment showed that the LMT formalism can successfully plan solutions for a… more

Low-resolution gamma-ray measurements of uranium enrichment

Description: Facilities that process special nuclear material perform periodic inventories. In bulk facilities that process low-enriched uranium, these inventories and their audits are based primarily on weight and enrichment measurements. Enrichment measurements determine the {sup 211}U weight fraction of the uranium compound from the passive gamma-ray emissions of the sample. Both international inspectors and facility operators rely on the capability to make in-field gamma-ray measurements of uranium enri… more

National Uranium Resource Evaluation: Torrington Quadrangle, Wyoming and Nebraska

Description: From Purpose and Scope of Study: "The Torrington 1ºx2º Quadrangle in southeastern Wyoming and a small area of westernmost Nebraska was evaluated to determine areas favorable for the occurrence of uranium deposits. Geologic environments (areally or stratigraphically restricted parts of a geologic unit) were placed in categories of favorable, unfavorable, or unevaluated."
