Implicit time stepping methods are useful for the simulation of large scale PDE systems because they avoid the time step limitations imposed by explicit stability conditions. To alleviate the challenges posed by computational and memory constraints, many applications solve the resulting linear systems by...
stable-diffusion-webui在安装时会克隆k-diffusion,放置到repositories目录下,如下图所示。同样的还会克隆stable-diffusion原始实现stable-diffusion-stability-ai,模型结构相关内容就会在这个库里。不同的采样器会使用不同的实现,euler a使用了kdiffusion库,而ddim和plms算法就使用stable-diffusion-stability-ai(位于该源码...
In this paper we propose convergence and stability properties of Euler method for solving fuzzy stochastic differential equations under generalized differentiability concept. It is used to find the analytical solution of method for some fuzzy stochastic differential equations (FSDEs). The related theorems...
The results show that the WENO scheme has high accuracy and good stability. And WENO scheme coupled with low dissipation E- CUSP algorithm is applied to the numerical solution of one- dimensional Euler equation. 5、 It has strong ability to capture contact discontinuities and shock waves, ...

Improvments of Euler-Chebyshev methods for solving roots of nonlinear equation are given.Their convergence properties are proved.They are at least seventh-order convergence and nineth-order convergence near simple root.In the end,numerical tests are given and compared with other known high order root...
Thus the stability behaviors of the thermoacoustic eigenmodes in the choked combustor are predicted. 1.4.3.1 Linearize Euler equation method In Ref. [78] the expression of choked outlet is validated in comparison with the numerical results of linear Euler equations. Here a linearized Euler equation...
entropy solution and corresponding approximate strong shock-fronts emanating from the vertex to the strong shock-front of the entropy solution. The regularity of strong shock-fronts emanating from the wedge vertex and the asymptotic stability of entropy solutions in the flow direction are also ...
The open questions that need to be addressed are the stability conditions, sensitivity to initial conditions, existence of periodicity in system orbits, etc. In this paper, we will first study the stability issue of SOSM under Euler’s discretization. We will show that for all values of ...
A generalized form of an N-step RK method is derived. With this generalized form, the criteria are derived for the three and four-step RK methods to be third and fourth-order time accurate for the non-linear equations, e.g., flow equations. These criteria are then applied to commonly ...
