HALOGENATED CHEMICALS: Role of Photolysis in Migration Studied.: As scientists, environmentalists and regulators continue to assess the risk posed by decabromodiphenyl ether (deca-BDE) flame retardant, primary research questions concern to what degree, if any, the compound is breaking down into less-brominated congeners in the environment, and what mechanisms may facilitate such a decomposition. Scientists at the...; Tags: decomposition, migration, NIST, polymer, radiation, scientist; Research articles 2004-07-01
Applying RUSLE 2.0 on burned-forest lands: an appraisal.: Forestlands disturbed by wildfire commonly constitute major and long-lasting sources of sediment that degrade water quality and cause siltation. Postfire restoration of the resistance to erosion of the forest soil is largely controlled by the rate of regrowth of vegetation and may take several years to return to prefire levels,...; Tags: appraisal, Databases, decomposition, HARDWARE, SOFTWARE, soil, Storage, U.S. Department of Agriculture; Research articles 2004-01-01

Application of symmetric orthogonal multiwavelets and prefilter technique for image compression: ABSTRACT Multiwavelets are new addition to the body of wavelet theory. There are many types of symmetric multiwavelets such as Geronimo-Hardin-Massopust GHM and Chui-Lian CL multiwavelets. However, the matrix filter generating the GHM system multiwavelets does not satisfy the symmetric property. For this reason, this paper presents a new...; Tags: ASCII, coefficient, decomposition, IEEE, Image, matrix, technique; Research articles 2003-04-01

Identification of shared components in large ensembles of time series using dimension reduction.: In this article we present a framework for parsimonious modeling of large ensembles of time series. The idea is to identify a small number of stochastic time series components such that each series in the ensemble is a weighted sum of series-specific realizations of the components. We present an estimation...; Tags: decomposition, G., Sec; Research articles 2002-09-01
Time-Parallel Algorithms for Solving PDEs: Tune-Parallel Algorithms for Solving PDEs A report presents additional details about a class of massively parallel algorithms for finite-difference numerical solution of time-dependent partial differential equations PDEs.

Credit effects in the monetary mechanism. (Session 3: Financial Markets and Institutions).: INTRODUCTION Monetary transmission is one of the great mysteries in economics. Namely, how can purchases or sales of just a few billion dollars in securities in the overnight reserve market have such large, persistent effects on overall spending? The traditional monetary transmission mechanism--a...; Tags: bank, decomposition, Federal Reserve Board, financial, Friedman, Morgan, Quality, Standards, standards; Research articles 2002-05-01
Vii. Productivity And Firm Dynamics: Evidence From Microdata - Review: Introduction and summary Chapters in the two previous issues of the OECD Economic Outlook (Nos. 67 and 68) discussed growth patterns in the OECD countries at the macroeconomic and sectoral levels. But growth of output and productivity takes place in individual firms, whose behaviour and decisions are influenced not...; Tags: decomposition, incumbent, manufacturing, OECD, productivity, Strategy, U.S.; Research articles 2001-06-01
Down on the Body Farm: The air smells sickeningly sweet, with honeysuckle and death. The Body Farm--the only place in the world where corpses rot in the open air to advance human knowledge--sits on a wooded hillside an easy three-minute stroll from the University of Tennessee Medical Center in Knoxville. Not everyone comes here voluntarily....; Tags: decomposition, Farm, FBI, Government; Research articles 2000-10-23
Discrete wavelet analysis of signals: ABSTRACT A discrete wavelet transform based on Daubechies coefficients is used to decompose a signal into levels. The method discussed is applicable to any signal of length 2^sup N^. Where the length is less than 2^sup N^ it is zero-padded to obtain the required length. A program written in MATLAB...; Tags: analysis, decomposition, IEEE; Research articles 1999-07-01
Keeping diesel fuel fresh - more important than you may think.: The improper storage of diesel fuel could have detrimental effects on vehicle performance and fuel efficiency. Diesel fuel that have been kept too long can cause filter and line clogging within the vehicle's engine and induce blisters and leaks in seals, hoses, pumps and injectors. It can also damage instrument...; Tags: decomposition, Diesel, emission, HARDWARE, molecule, Storage, U.S. Environmental Protection Agency; Research articles 1993-11-01
Static Efficiency Decompositions And Capacity Utilisation: Integrating Economic And Technical Capacity Notions: Starting from existing static decompositions of overall economic efficiency on non-parametric production and cost frontiers, this paper proposes more comprehensive decompositions including several cost-based notions of capacity utilisation. Furthermore, in case prices are lacking, additional decompositions of overall technical efficiency integrating a technical concept of capacity utilization were developed. These...; Tags: Decomposition, University Of Antwerp, Capacity Utilisation; White papers 2007-03-01
