Two-moment scheme for general-relativistic radiation hydrodynamics: a systematic description and new applications [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT We provide a systematic description of the steps necessary – and of the potential pitfalls to be encountered – when implementing a two-moment scheme within an implicit–explicit (IMEX) scheme to include radiative-transfer contributions in numerical simulations of general-relativistic (magneto-)hydrodynamics (GRMHD).

Comparing macroscopic continuum models for rarefied gas dynamics : a new test method [PDF]
, 2006 We propose a new test method for investigating which macroscopic continuum models, among the many existing models, give the best description of rarefied gas flows over a range of Knudsen numbers.

On Moving Object Reconstruction By Moments [PDF]
, 2002 Recent research using statistical moments to describe moving shapes through an image sequence has led to an interest in reconstructing moving shapes from their moment description. This paper discusses how the moment description through a series of frames

An aerosol transport model based on a two‐moment microphysical parameterization in the Venus middle atmosphere: Model description and preliminary experiments [PDF]
Journal of Geophysical Research: Planets, 2006 On Venus, the upper haze layer (70–90 km) is observed above the cloud layer (48–70 km). An aerosol transport model using a two‐moment microphysical parameterization for the cloud and upper haze is developed and is applied to a wide height range of 24–94 km. The latitudinal dependence of the SO2 oxidation mainly leads to the equator‐pole contrast of the

Continued fractions which correspond to two series expansions and the strong Hamburger moment problem [PDF]
, 2012 Just as the denominator polynomials of a J-fraction are orthogonal polynomials with respect to some moment functional, the denominator polynomials of an M-fraction are shown to satisfy a skew orthogonality relation with respect to a stronger moment ...

Interactive effects of joint angle, contraction state and method on estimates of achilles tendon moment arms [PDF]
, 2013 Copyright @ 2013 Human Kinetics, IncThe muscle-tendon moment arm is an important input parameter for musculoskeletal models. Moment arms change as a function of joint angle and contraction state and depend on the method being employed.

Open Markov Chains: Cumulant Dynamics, Fluctuations and Correlations
Entropy, 2021 In this work we propose a model for open Markov chains that can be interpreted as a system of non-interacting particles evolving according to the rules of a Markov chain.

Form at its Limits: Edward Said, Marxism, and the Valences of Critique
Open Library of Humanities, 2018 In his 1936 essay ‘Narrate or Describe’, György Lukács writes: ‘when a writer attempts as an observer and describer to achieve a comprehensive description, he must either reject any principle of selection, undertake an inexhaustible labour of Sisyphus or

Physical Review Research, 2023 While optics and mechanics are two distinct branches of physics, they are connected. It is well known that the geometrical/ray treatment of light has direct analogies to mechanical descriptions of particle motion.
