Thermal Pressurization and Onset of Melting in Fault Zones
(American Geophysical Union, 2006)
We examine how frictional heating drives the evolution of temperature, strength, and fracture energy during earthquake slip. For small slip distances, heat and pore fluid are unable to escape the shearing fault core, and ...
Does Shear Heating of Pore Fluid Contribute to Earthquake Nucleation?
(American Geophysical Union, 2006)
Earthquake nucleation requires reduction of frictional strength \(\tau = \mu (\sigma - p) \) with slip or slip rate, where \(\mu, \sigma_n\), and \(p\) are the friction coefficient, normal stress, and fluid pressure, ...
A Multi-Site Analysis of Random Error in Tower-Based Measurements of Carbon and Energy Fluxes
(Elsevier, 2006)
Measured surface-atmosphere fluxes of energy (sensible heat, <i>H</i>, and latent heat, LE) and CO2 (<i>F</i>CO2) represent the "true" flux plus or minus potential random and systematic measurement errors. Here, we use data ...
Advanced Forensic Format: An Open, Extensible Format for Disk Imaging
(International Federation for Information Processing, 2006)
This paper describes the Advanced Forensic Format (AFF), which is designed as an alternative to current proprietary disk image formats. AFF offers two significant benefits. First, it is more flexible because it allows ...
Simpler TAG semantics through synchronization
(Center for the Study of Language and Information, 2006)
In recent years Laura Kallmeyer, Maribel Romero, and their collaborators
have led research on TAG semantics through a series of papers refining a system of TAG semantics computation. Kallmeyer and Romero bring together ...
Referring-expression generation using a transformation-based learning approach
(Assocation for the Advancement of Artifical Intelligence, 2006)
A natural language generation system must generate expressions that allow a reader to identify the entities to which they refer. This paper describes the creation of referring-expression (RE) generation models developed ...
Formaldehyde Distribution over North America: Implications for Satellite Retrievals of Formaldehyde Columns and Isoprene Emission
(American Geophysical Union, 2006)
Formaldehyde (HCHO) columns measured from space provide constraints on emissions of volatile organic compounds (VOCs). Quantitative interpretation requires characterization of errors in HCHO column retrievals and relating ...
Transpacific Transport of Asian Anthropogenic Aerosols and its Impact on Surface Air Quality in the United States
(American Geophysical Union, 2006)
We use satellite (MODIS) observations of aerosol optical depths (AODs) over the North Pacific, together with surface aerosol measurements at a network of remote U.S. sites (IMPROVE), to improve understanding of the ...
Using CO2:CO Correlations to Improve Inverse Analyses of Carbon Fluxes
(American Geophysical Union, 2006)
Observed correlations between atmospheric concentrations of CO2 and CO represent potentially powerful information for improving CO2 surface flux estimates through coupled CO2-CO inverse analyses. We explore the value of ...
Inverse Shade Trees for Non-Parametric Material Representation and Editing
(Association for Computing Machinery, 2006)
Recent progress in the measurement of surface reflectance has created a demand for non-parametric appearance representations that are accurate, compact, and easy to use for rendering. Another crucial goal, which has so far ...
