This new explicit method increases stability of the original super-time-stepping whenever the skew-symmetric term is nonzero, which occurs in particular convection-diffusion problems and more generally when the iteration matrix represents a nonlinear operator. The new method is stable for skew ...
0 is a symmetric positive definite discontinuous (possibly anisotropic) full diffusion tensor, g is a source term, and n is the exterior normal vector. ... K Nikitin,K Terekhov,Y Vassilevski - 《Computational Geosciences》 被引量: 17发表: 2014年 Increase and saturation of the third order hy...
Recently, all semi-classical monic orthogonal polynomial sequences of class one satisfying a three-term recurrence relation with βn=(1)nβ0, n≥0, β0∈{0} have been determined (see [B. Bouras and A. Alaya, A large family of semi-classical polynomials of class one, Integral Transforms...
The left hand side of the second condition in (6) can be rewritten as Since y/m2 > mi, ^/rn^ > mi (as the nth power integral mean ^Jmn is an increasing function of n) the first term here is nonpositive the second is nonnegative (moreover positive, if the first condition of (...
The idea is to prescribe an Hi that activates the skew– symmetric term σi× of (20), generating couple stresses τ ji and therefore micro–rotations θi . These rotations are closely related to the existence of the microstructure, introduced in the FE model by the lb and lt scale ...
The former are the risk-return characteristics can be divided into symmetry, derivatives, and is mainly refers to long-term, futures and swaps, and options are non-symmetrical, derivatives, and their risk-return charac 翻译结果5复制译文编辑译文朗读译文返回顶部 Grows the tool to be possible to ...
{C}^n, \\\lVert \\\cdot Vert )^m$ up to a logarithmic term $(c \\\log n)^{m^2}$ can be estimated by the norm of $P$ on $ (\\\mathbb{C}^n, \\\lVert \\\cdot Vert )$; here $c \\\ge 1$ denotes a universal constant. Moreover, for the $\\\ell_p$"~norms $...
fails to be parabolic since it is missing the diffusive term \(\delta _x u\) , but it is easily seen to satisfy hörmander’s finite rank condition for the hypoellipticity. equivalently, one can verify that \(k(t)=\begin{pmatrix} i_n &{} t/2\ i_n\\ t/2\ i_n&{} t^2/...
In more detail, using an operator-theoretic approach, the uncertain non-symmetric backlash is described as a generalized Lipschitz operator and a bounded parasitic term. Since the generalized Lipschitz operator is unknown, a new robust condition using robust right coprime factorization is proposed to ...
It allows circumferential changes of the radius but takes advantage of the fact that it is only the second term in a Fourier series expansion that has a major influence on the dynamic behaviour of the rotor. The element allows transverse shear and moreover the mass is not distributed on the...
