Acid solution absorption of extruded polyethylene foam

Description: Water and acid absorption tests of samples of a proposed replacement to current polyethylene foam used as fill material on the FB-Line cation columns have been completed. Water and nitric acid solution absorption of up to 4 volume percent was observed over approximately a 4 month period of time. Because of the nuclear safety implications, liquid absorption of a replacement fill material must be low. EthafoaM[trademark] 220 extruded polyethylene, a product available from Dow Chemical Company appears to be a good candidate material for replacement of the existing fill material. Establishment of 5 volume percent solution absorption specification appears to be both reasonable and achievable for a replacement foam, provided it is acceptable to nuclear safety personnel.

Field shape measurements of prototype Main Injector dipole endpacks

Description: Measurements of the transverse dependence of the flux on the symmetry plane were obtained on a series of endpacks mounted on a Main Injector prototype dipole. From these flux measurements, we determined the endfield shape, expressed in terms of normal harmonics, up to 14-pole. We describe the measurement and analysis procedure, and present the results for all endpacks that were tested. The final endpack (number 10) has a sextupole, normalized to the body, of +0.167 {plus_minus} .072 units, and the relative field shape deviates by {lt} 1.2 units relative to the on-axis field strength over the range {vert_bar}x{vert_bar} {lt} 2.0{double_prime}. These measurements indicate that Endpack 10 meets the requirements for the Main Injector dipole.

These measurements indicate that Endpack 10 meets the requirements for the Main Injector dipole.

Assessing impacts of climate change on forests: The state of biological modeling

Description: Models that address the impacts to forests of climate change are reviewed by four levels of biological organization: global, regional or landscape, community, and tree. The models are compared as to their ability to assess changes in greenhouse gas flux, land use, maps of forest type or species composition, forest resource productivity, forest health, biodiversity, and wildlife habitat. No one model can address all of these impacts, but landscape transition models and regional vegetation and land-use models consider the largest number of impacts. Developing landscape vegetation dynamics models of functional groups is suggested as a means to integrate the theory of both landscape ecology and individual tree responses to climate change. Risk assessment methodologies can be adapted to deal with the impacts of climate change at various spatial and temporal scales. Four areas of research development are identified: (1) linking socioeconomic and ecologic models, (2) interfacing forest models at different scales, (3) obtaining data on susceptibility of trees and forest to changes in climate and disturbance regimes, and (4) relating information from different scales.

Flow volumes for interactive vector field visualization

Description: Flow volumes are the volumetric equivalent of stream lines. They provide more information about the vector field being visualized than do stream lines or ribbons. Presented is an efficient method for producing flow volumes, composed of transparently rendered tetrahedra, for use in an interactive system. The problems of rendering, subdivision, sorting, rendering artifacts, and user interaction are dealt with.

Texture splats for 3D vector and scalar field visualization

Description: Volume Visualization is becoming an important tool for understanding large 3D datasets. A popular technique for volume rendering is known as splatting. With new hardware architectures offering substantial improvements in the performance of rendering texture mapped objects, we present textured splats. An ideal reconstruction function for 3D signals is developed which can be used as a texture map for a splat. Extensions to the basic splatting technique are then developed to additionally represent vector fields.
