Rescaling velocity methods have been widely used in the last years to solve numerically a large class of partial or even integro-differential equations exhibiting concentration or spreading,without the use of remeshing technique.

近年来大量调查结果和实验室研究表明环境中的内分泌干扰物(EDCs)对动物和人类的生殖与健康的危害具有不容忽视的作用[1-4].虽然环境地表水中的EDCs污染调查已较多[9-10,14],但研究人员通常习惯利用传统过滤(滤膜孔径通常为0.7μm 或0.45μm)将天然水体分离为水和悬浮颗粒物两类介质来进行分类研究,而往往忽略了纳米尺度的胶体物质,将它们与真溶液一起笼统归为"水相"或"溶解相".由于胶
疏水性有机化合物(HOCs)和表面活性剂往往共存于自然环境中,对生态环境产生潜在的风险,甚至会通过直接暴露或食物链的传递对人类健康产生危害.另外,共存的表面活性剂会吸附在水体、土壤和微生物等多介质微界面上,由于其具有亲水和亲油的特性,会在HOCs、表面活性剂和微生物之间产生复杂的相互作用.
Size-resolved effective density,mixing state,and hygroscopicity of submicrometer smoke particles from 5 major agricultural residues burning were characterized using an aerosol chamber system,including
We consider the approximation in the reaction-diffusion norm with continuous finite elements and prove that the best error is equivalent to a sum of local best errors on pairs of elements.
Sharp a posteriori error estimators for obstacle problems rely on an approximation of the Lagrange multiplier associated with the exact solution.
This talk considers the non-conforming Crouzeix-Raviart finite element method(NCFEM)for the discretisation of the obstacle problem.
We consider optimal control problem governed by PDEs with stochastic perturbation in its coefficients.The objective is to minimize the expectation of a cost functional with the constrained control.
An adaptive finite element algorithm for problems in elastoplasticity with hardening is of optimal convergence with respect to the notion of approximation classes.
The Monte Carlo(and Multi-level Monte Carlo)finite element method can be used to approximate observables of solutions to diffusion equations with lognormal distributed diffusion coefficients,e.g.
In this talk,I will present joint work with C.Hauck(ORNL)and M.Murillo(LANL)on velocity-dependent multi-species BGK models for dense plasmas.
