ACME algorithms for contact in a multiphysics environment API version 2.2.

Description: An effort is underway at Sandia National Laboratories to develop a library of algorithms to search for potential interactions between surfaces represented by analytic and discretized topological entities. This effort is also developing algorithms to determine forces due to these interactions for transient dynamics applications. This document describes the Application Programming Interface (API) for the ACME (Algorithms for Contact in a Multiphysics Environment) library.

An analytically solvable eigenvalue problem for the linear elasticity equations.

Description: Analytic solutions are useful for code verification. Structural vibration codes approximate solutions to the eigenvalue problem for the linear elasticity equations (Navier's equations). Unfortunately the verification method of 'manufactured solutions' does not apply to vibration problems. Verification books (for example [2]) tabulate a few of the lowest modes, but are not useful for computations of large numbers of modes. A closed form solution is presented here for all the eigenvalues and eige… more

Automated infrasound signal detection algorithms implemented in MatSeis - Infra Tool.

Description: MatSeis's infrasound analysis tool, Infra Tool, uses frequency slowness processing to deconstruct the array data into three outputs per processing step: correlation, azimuth and slowness. Until now, an experienced analyst trained to recognize a pattern observed in outputs from signal processing manually accomplished infrasound signal detection. Our goal was to automate the process of infrasound signal detection. The critical aspect of infrasound signal detection is to identify consecutive proce… more

BigHorn Home Improvement Center: Proof that a Retail Building Can Be a Low Energy Building: Preprint

Description: The BigHorn Home Improvement Center in Silverthorne, Colorado was one of the first commercial buildings in the United States to integrate extensive high-performance design into a retail space. After monitoring and evaluation by NREL, the BigHorn Center was found to consume 54% less source energy and have 53% lower energy costs than typical retail buildings of similar size. The extensive use of daylighting to replace electric lighting reduced lighting energy requirements by 80% and significantly… more

Carbon Dioxide Capture From Flue Gas Using Dry Regenerable Sorbents Quarterly Technical Progress Report: April-June 2004

Description: This report describes research conducted between April 1, 2004 and June 30, 2004 on the preparation and use of dry regenerable sorbents for removal of carbon dioxide from flue gas. Support materials and supported sorbents were prepared by spray drying. Sorbents consisting of 20 to 50% sodium carbonate on a ceramic support were prepared by spray drying in batches of approximately 300 grams. The supported sorbents exhibited greater carbon dioxide capture rates than unsupported calcined sodium bic… more

Carbon Sequestration in Reclaimed Mined Soils of Ohio

Description: This research project is aimed at assessing the soil organic carbon (SOC) sequestration potential of reclaimed minesoils (RMS). The experimental sites, owned and maintained by the American Electrical Power, are located in Guernsey, Morgan, Noble, and Muskingum Counties of Ohio. These sites, characterized by age chronosequences, were reclaimed with and without topsoil application and are under continuous grass or forest cover. During this quarter, bulk and core soil samples were collected from a… more

Coherent infrared radiation from the ALS generated via femtosecond laser modulation of the electron beam

Description: Interaction of an electron beam with a femtosecond laser pulse co-propagating through a wiggler at the ALS produces large modulation of the electron energies within a short {approx}100 fs slice of the electron bunch. Propagating around the storage ring, this bunch develops a longitudinal density perturbation due to the dispersion of electron trajectories. The length of the perturbation evolves with a distance from the wiggler but is much shorter than the electron bunch length. This perturbation… more

Comparative Analysis of Homebuyer Response to New Zero-Energy Homes: Preprint

Description: In 2004, mail questionnaires were sent to 271 homebuyers in a highly energy-efficient community and 98 homebuyers living in an adjacent conventional community. People surveyed had to have lived in their homes for at least 6 months. The questionnaires addressed perceptions and preferences relative to the new home purchases, and the role, if any, that energy efficiency and solar features might have played in these purchases. Also investigated was the willingness to pay for energy features; prefer… more

Compressing bitmap indices by data reorganization

Description: Many scientific applications generate massive volumes of data through observations or computer simulations, bringing up the need for effective indexing methods for efficient storage and retrieval of scientific data. Unlike conventional databases, scientific data is mostly read-only and its volume can reach to the order of petabytes, making a compact index structure vital. Bit map indexing has been successfully applied to scientific databases by exploiting the fact that scientific data are enume… more
