A New Approximation for the Null Distribution of the Likelihood Ratio Test Statistics for k Outliers in a Normal Sample

Usually when performing a statistical test or estimation procedure, we assume the data are all observations of i.i.d. random variables, often from a normal distribution. Sometimes, however, we notice in a sample one or more observations that stand out from the crowd. These observation(s) are commonly called outlier(s). Outlier tests are more formal procedures which have been developed for detec...

The dust distribution in edge-on galaxies Radiative transfer fits of V and K’-band images

Aims. I have analyzed a sample of seven nearby edge-on galaxies observed in the V and K’-band, in order to infer the properties of the dust distribution. Methods. A radiative transfer model, including scattering, have been used to decompose each image into a stellar disk, a bulge, and a dust disk. The parameters describing the distributions have been obtained through standard χ2 minimization te...

Spectral Modeling of Radiative Heat Transfer in Carbonaceous Atmospheres Using New k-Distribution Models and Databases

Multi-scale correlated-k distribution models are presented for the red and violet bands of CN for applications relevant to entry into the atmospheres of Titan, Mars, Venus and flows over an ablating heat shield. In the multi-scale model spectral lines are separated into different scales to improve correlation among absorption coefficients. The methodology for scaling absorption coefficients int...

A Narrow Band-Based Multiscale Multigroup Full-Spectrum k-Distribution Method for Radiative Transfer in Nonhomogeneous Gas-Soot Mixtures

The full-spectrum k-distribution (FSK) approach has become a promising method for radiative heat transfer calculations in strongly nongray participating media, due to its ability to achieve high accuracy at a tiny fraction of the line-by-line (LBL) computational cost. However, inhomogeneities in temperature, total pressure, and component mole fractions severely challenge the accuracy of the FSK...
