Adaptive node techniques for Maxwell's equations

Description: The computational mesh in numerical simulation provides a framework on which to monitor the spatial dependence of function and their derivatives. Spatial mesh is therefore essential to the ability to integrate systems in time without loss of fidelity. Several philosophies have emerged to provide such fidelity (Eulerian, Lagrangian, Arbitrary Lagrangian Eulerian ALE, Adaptive Mesh Refinement AMR, and adaptive node generation/deletion). Regardless of the type of mesh, a major difficulty is in set… more

ADVANCED FLUE GAS CONDITIONING AS A RETROFIT UPGRADE TO ENHANCE PM COLLECTION FROM COAL-FIRED ELECTRIC UTILITY BOILERS

Description: The U.S. Department of Energy and ADA Environmental Solutions has begun a project to develop commercial flue gas conditioning additives. The objective is to develop conditioning agents that can help improve particulate control performance of smaller or under-sized electrostatic precipitators on utility coal-fired boilers. The new chemicals will be used to control both the electrical resistivity and the adhesion or cohesivity of the flyash. There is a need to provide cost-effective and safer alt… more

Calculation of 239pu(n,n') cross sections to 5 MeV

Description: Calculations of the {sup 239}Pu(n,n') cross section and other relevant cross sections for incident neutron energies of up to 5 MeV are presented. Two components of the {sup 239}Pu(n,n') cross section are included. The direct contribution to the {sup 239}Pu(n,n') cross section is computed by the coupled-channel optical model. The compound component is calculated by a Hauser-Feshbach statistical treatment. Fission and {gamma}-cascade processes are considered as competing channels in the compound-… more

CHARACTERIZATION OF PROPANE MONOOXYGENASE: INITIAL MECHANISTIC STUDIES

Description: Extensive industrial and DOE use of chlorinated hydrocarbons has resulted in widespread soil and ground-water contamination. Bioremediation is a potential remedy because various bacterial strains degrade chlorinated compounds, including trichloroethylene (TCE). Previous reports indicated that the propane monooxygenase (PMO) enzyme from Mycobacterium vaccae degraded TCE. These reports included additional substrates and resulting products that were inconsistent with PMO forming an epoxide interme… more

Characterization of Si nanostructures using internal quantum efficiency measurements

Description: Hemispherical reflectance and internal quantum efficiency measurements have been employed to evaluate the response of Si nanostructured surfaces formed by using random and periodic reactive ion etching techniques. Random RIE-textured surfaces have demonstrated solar weighted reflectance of {approx} 3% over 300--1,200-nm spectral range even without the benefit of anti-reflection films. Random RIE-texturing has been found to be applicable over large areas ({approximately} 180 cm{sup 2}) of both s… more

Cle Elum Lake Anadromous Salmon Restoration Feasibility Study: Summary of Research, 1986-1999 Progress Report.

Description: The focus of this research was to study the feasibility for anadromous salmonids to recolonize the habitat above reservoirs in the Yakima River without disruption to irrigation withdrawals. A primary concern was whether anadromous fish could successfully exit reservoirs and survive downstream passage through the Yakima and Columbia Rivers to the ocean.

Computational methods for coupling microstructural and micromechanical materials response simulations

Description: Computational materials simulations have traditionally focused on individual phenomena: grain growth, crack propagation, plastic flow, etc. However, real materials behavior results from a complex interplay between phenomena. In this project, the authors explored methods for coupling mesoscale simulations of microstructural evolution and micromechanical response. In one case, massively parallel (MP) simulations for grain evolution and microcracking in alumina stronglink materials were dynamicall… more
