Technical Note: Convergence analysis of a polyenergetic SART algorithm

Creator:: Humphries, T.
Abstract:: PURPOSE: We analyze a recently proposed polyenergetic version of the simultaneous algebraic reconstruction technique (SART). This algorithm, denoted pSART, replaces the monoenergetic forward projection operation used by SART with a post-log, polyenergetic forward projection, while leaving the rest of the algorithm unchanged. While the proposed algorithm provides good results empirically,...

Examination of moisture content variation within an operational wet deck

Creator:: Schimleck, Laurence, Love-Myers, Kim, Sanders, Joe, Raybon, Heath, Daniels, Richard, Andrews, Edward, and Schilling, Erik
Abstract:: Many forest products companies in the southeastern United States store large volumes of round-wood under wet storage. Log quality depends on maintaining a high and constant wood moisture content; however, limited knowledge exists regarding moisture variation within individual logs, and within wet decks as a whole, making it impossible to...

Technical note: Time lag correction of aquatic eddy covariance data measured in the presence of waves

Creator:: Berg, P., Reimers, Clare E., Rosman, J. H., Huettel, M., Delgard, M. L., Reidenbach, M. A., and Özkan-Haller, H. Tuba
Abstract:: Extracting benthic oxygen fluxes from eddy covariance time series measured in the presence of surface gravity waves requires careful consideration of the temporal alignment of the vertical velocity and the oxygen concentration. Using a model based on linear wave theory and measured eddy covariance data, we show that a substantial...

Relationship Between Wildfire, Salvage Logging, and Occupancy of Nesting Territories by Northern Spotted Owls

Creator:: Clark, Darren A., Anthony, Robert G., and Andrews, Lawrence S.
Abstract:: The northern spotted owl (Strix occidentalis caurina) is one of the most intensively studied raptors in the world; however, little is known about the impacts of wildfire on the subspecies and how they use recently burned areas. Three large-scale wildfires in southwest Oregon provided an opportunity to investigate the short-term...

Technical change and pollution abatement costs

Creator:: Färe, Rolf, Grosskopf, Shawna, and Pasurka, Carl
Abstract:: There is continuing interest in the trend of costs associated with pollution abatement activities. We specify an environmental production technology to model the joint production of good and bad outputs. The joint production model calculates pollution abatement costs and identifies changes in these costs associated with: (1) technical change, (2)...

Hexagonal global parameterization of arbitrary surfaces

Creator:: Nieser, Matthias, Palacios, Jonathan, Polthier, Konrad, and Zhang, Eugene
Abstract:: In this paper we introduce hexagonal global parameterizations, a new type of parameterization in which parameter lines respect six-fold rotational symmetries (6-RoSy). Such parameterizations enable the tiling of surfaces with regular hexagonal texture and geometry patterns and can be used to generate high-quality triangular remeshing. To construct a hexagonal parameterization...

ARK: Aggregation of Reads by K-Means for Estimation of Bacterial Community Composition

Creator:: Koslicki, David, Chatterjee, Saikat, Shahrivar, Damon, Walker, Alan W., Francis, Suzanna C., Fraser, Louise J., Vehkaperä, Mikko, Lan, Yueheng, and Corander, Jukka
Abstract:: Motivation: Estimation of bacterial community composition from high-throughput sequenced 16S rRNA gene amplicons is a key task in microbial ecology. Since the sequence data from each sample typically consist of a large number of reads and are adversely impacted by different levels of biological and technical noise, accurate analysis of...
