Finite-volume schemes developed in the meteorological community that permit long time steps are considered. These include Eulerian flux-form schemes as well as fully two-dimensional and cascade cellintegrated semi-Lagrangian (CISL) schemes. A oneand two-dimensional Von Neumann stability analysis of these finite-volume advection schemes is given. Contrary to previous analysis, no simplifications...

The acceleration statistics of sheared and rotating homogeneous turbulence are studied using direct numerical simulation results. The statistical properties of Lagrangian and Eulerian accelerations are considered together with the influence of the rotation to shear ratio, as well as the scale dependence of their statistics. The probability density functions (pdfs) of both Lagrangian and Euleria...

In this paper, we introduce the definitions of Eulerian pair and Hermite-Biehler pair. We also characterize a duality relation between recurrences recurrence systems. This generalizes unifies decompositions several enumerative polynomials, including up-down run polynomials for symmetric groups, alternating hyperoctahedral flag descent groups ascent-plateau Stirling permutations. derive some pro...

In this paper, a new general procedure is presented for modeling the effects of large displacements on the response of space frames subjected to conservative loading. An incremental definition of rotations is adopted based on an improved rotational transformation matrix, and a convected (Eulerian) system is employed for establishing the contribution of individual elements to the strain energy (...

A relativistic Eulerian Vlasov code is presented to simulate laser-plasma interactions. Eulerian Vlasov codes have a very low noise level and allow detailed analysis of lowdensity regions of phase-space. The code we present is 1D (one space dimension x and one momentum dimension px) with a fluid momentum py, and includes both ion and electron dynamics. The laser is incident from the left as a t...

A closed set of exact equations describing statistical theory of turbulent self-diffusion by multivariate-normal turbulent velocity field is derived. In doing so, we first suggest exact formulas for correlations 〈fi(p)fj(p ′)R[f ]〉, 〈g(p)R[f ]〉 and 〈g(p)fj(p ′)R[f ]〉 when the functional R[f ] is functional of functions fi’s having multivariate-normal distribution, g and fi’s have joint normal d...

This paper presents a new approach for the geometrically nonlinear analysis of thin-walled space frames. The proposed approach employs an Eulerian (convected) system for the definition of local element freedoms, and is capable of representing the effects of large displacements, finite rotations and cross-sectional warping. The use of the Eulerian system has been shown to be advantageous in the ...

By means of Monte Carlo simulations and a finite-size scaling analysis, we find a critical line of an n-component Eulerian face-cubic model on the square lattice and the simple cubic lattice in the region v>1, where v is the bond weight. The phase transition belongs to the Ising universality class independent of n. The critical properties of the phase transition can also be captured by the perc...

In this article, we generalize the concepts of Eulerian and Hamiltonian digraphs to directed hypergraphs. A dihypergraph H is a pair (V(H), E(H)), where V(H) is a non-empty set of elements, called vertices, and E(H) is a collection of ordered pairs of subsets of V(H), called hyperarcs. It is Eulerian (resp. Hamiltonian) if there is a dicycle containing each hyperarc (resp. each vertex) exactly ...
