Simulation of rotating objects in fluids with the cumulant lattice Boltzmann model on sliding meshes
Computers and Mathematics with Applications, 2020 In this paper a rotating grid technique for the cumulant lattice Boltzmann model is presented. The rotating object is embedded in a rotating mesh that communicates with an enclosing stationary mesh via compact quadratic interpolation.

Convergence Characteristics of the Cumulant Expansion for Fourier Path Integrals [PDF]
, 2010 The cumulant representation of the Fourier path integral method is examined to determine the asymptotic convergence characteristics of the imaginary-time density matrix with respect to the number of path variables $N$ included. It is proved that when the

Highly Accurate Two-Dimensional Direction Finding Using Cumulant
IEEE Access, 2018 This paper proposes a new two-dimensional direction finding algorithm for estimating multiple non-Gaussian signals using cumulants. This new algorithm: 1) employs an array geometry consisting of a nine-element non-uniformly spaced cross-shaped sub-array ...

Cumulants, free cumulants and half-shuffles [PDF]
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2015 Free cumulants were introduced as the proper analogue of classical cumulants in the theory of free probability. There is a mix of similarities and differences, when one considers the two families of cumulants. Whereas the combinatorics of classical cumulants is well expressed in terms of set partitions, that of free cumulants is described and often ...

Mixed-Field Source Localization Based on the Non-Hermitian Matrix
Information, 2020 In this paper, an efficient high-order multiple signal classification (MUSIC)-like method is proposed for mixed-field source localization. Firstly, a non-Hermitian matrix is designed based on a high-order cumulant.
