Evaluating late detection capability against diverse insider adversaries

Description: This paper describes a model for evaluating the late (after-the-fact) detection capability of material control and accountability (MCandA) systems against insider theft or diversion of special nuclear material. Potential insider cover-up strategies to defeat activities providing detection (e.g., inventories) are addressed by the model in a tractable manner. For each potential adversary and detection activity, two probabilities are assessed and used to fit the model. The model then computes the … more

Fuel Effects on a Low-Swirl Injector for Lean Premixed Gas Turbines

Description: Laboratory experiments have been conducted to investigate the fuel effects on the turbulent premixed flames produced by a gas turbine low-swirl injector (LSI). The lean-blow off limits and flame emissions for seven diluted and undiluted hydrocarbon and hydrogen fuels show that the LSI is capable of supporting stable flames that emit < 5 ppm NO{sub x} ({at} 15% O{sub 2}). Analysis of the velocity statistics shows that the non-reacting and reacting flowfields of the LSI exhibit similarity feat… more

Algorithm refinement for fluctuating hydrodynamics

Description: This paper introduces an adaptive mesh and algorithmrefinement method for fluctuating hydrodynamics. This particle-continuumhybrid simulates the dynamics of a compressible fluid with thermalfluctuations. The particle algorithm is direct simulation Monte Carlo(DSMC), a molecular-level scheme based on the Boltzmann equation. Thecontinuum algorithm is based on the Landau-Lifshitz Navier-Stokes (LLNS)equations, which incorporate thermal fluctuations into macroscopichydrodynamics by using stochastic… more

Selected Small Business Statistics

Description: This report gathers selected statistics on the role of small businesses in the national economy that Congress has frequently asked the Congressional Research Service (CRS) to provide. Most of the statistics are calculated by CRS from Census data. The report uses the widely accepted research definition that a small business has fewer than 500 employees.

Poverty in the United States: 2008

Description: This report examines poverty in the United States. In 2008, 39.8 million people were counted as poor in the United States - an increase of 2.6 million persons from 2007, and nearly the largest number of persons counted as poor since 1960. The poverty rate, or percent of the population considered poor under the official definition, was reported at 13.2%; this is up from 12.5% in 2007, and is the highest rate since 1997. The recent increase in poverty reflects the worsening of economic conditions… more

Mechanical Characterization of Nodular Ductile Iron

Description: The objective of this study is to characterize the strength and fracture response of nodular ductile iron (NDI) and its underlying ferritic matrix phase. Quasistatic and split Hopkinson pressure bar (SHPB) compression tests were performed on NDI and a model material for the NDI matrix phase (Fe-Si alloy). Smooth and notch round bar (NRB) samples were loaded in tension until fracture to determine strain-at-failure with varying stress triaxiality. Multiple tests were performed on each small and l… more

Proton Angular Distribution for 90 Mev Neutron-proton Scattering

Description: The angular distribution of the recoil protons in neutron-proton scattering at 90 Mev has been measured for angles between 5{sup o} and 65{sup o} from the direction of the neutron beam. The neutrons were produced by stripping 190 Mev deuterons in a 1/2 inch Be target in the 184-inch F.M. cyclotron. R. Serber has calculated the neutron energy distribution; it has a peak at 90 Mev and a half width of 27 Mev. This distributiQn has been checked experimentally for the neutrons by Wilson Powell and b… more

Mapping the Dark Matter From UV Light at High Redshift: An Empirical Approach to Understand Galaxy Statistics

Description: We present a simple formalism to interpret the observations of two galaxy statistics, the UV luminosity function (LF) and two-point correlation functions for star-forming galaxies at z {approx} 4, 5 and 6 in the context of {Lambda}CDM cosmology. Both statistics are the result of how star formation takes place in dark matter halos, and thus are used to constrain how UV light depends on halo properties, in particular halo mass. The two physical quantities we explore are the star formation duty cy… more

Unsupervised Group Discovery and LInk Prediction in Relational Datasets: a nonparametric Bayesian approach

Description: Clustering represents one of the most common statistical procedures and a standard tool for pattern discovery and dimension reduction. Most often the objects to be clustered are described by a set of measurements or observables e.g. the coordinates of the vectors, the attributes of people. In a lot of cases however the available observations appear in the form of links or connections (e.g. communication or transaction networks). This data contains valuable information that can in general be exp… more

Probing the Disk-Jet Connection of the Radio Galaxy 3C120 Observed With Suzaku

Description: Broad line radio galaxies (BLRGs) are a rare type of radio-loud AGN, in which the broad optical permitted emission lines have been detected in addition to the extended jet emission. Here we report on deep (40ksec x 4) observations of the bright BLRG 3C 120 using Suzaku. The observations were spaced a week apart, and sample a range of continuum fluxes. An excellent broadband spectrum was obtained over two decades of frequency (0.6 to 50 keV) within each 40 ksec exposure. We clearly resolved the … more
