In this talk,we give some necessary conditions,presented as criteria of Kalmans type,for the approximate null controllability,the approximate synchronization and the approximate synchronization by groups respectively,for a coupled system of wave equations with Dirichlet boundary controls.

近年来,环境中存在的药物和个人护理产品(PPCPs) 残留在全世界范围内都受到了越来越多的关注[1].迄今为止,除了对少数手性农药的环境行为和毒理学开展了一些研究外,对人用手性药物的环境浓度和毒理学研究,尚未见报道.
阿散酸(p-ASA)因有促进动物生长、提高饲料效率、防治痢疾等作用而作为一种饲料添加剂应用于禽畜养殖业,如养猪场等[1].然而因p-ASA几乎不为消化道所吸收,故其经由动物体排出时基本保持不变[2].这表明p-ASA很容易释放到养殖业环境中,并最终进入污水系统.
随着现代工业的迅猛发展,采矿、冶金、染料、玻璃、蓄电池等工业废水携带大量的有毒有害重金属进入水体.重金属无法被生物降解和破坏,随食物链富集,造成了日益严重的水体重金属污染问题和生态破坏.目前常用治理方法中,吸附法因其高去除效率、经济便捷性被认为是最有效的技术之一.其中,无机纳米吸附剂由于其独特的物理化学性质而获得广泛研究.
电吸附脱盐,因其效率高、能耗低和吸附脱附性能优异等优势,已成为一种重要的水处理技术.它已逐渐成为21世纪在经济有效海水脱盐及废水循环再次利用等方面解决水资源短缺问题的重要策略之一 [1-3].
近年来,多溴联苯醚(PBDEs）已成为大气、水体、土壤和生物体等多环境介质中普遍检出且极具生态风险的有机污染物而备受环境科学工作者的广泛关注.为消除或阻控PBDEs的生态环境污染风险,开展高效微生物降解及其相关分子调控机制研究,具有重要的科学意义和实践指导价值.其中,好氧微生物降解具有其高效、快速且降解较为彻底等特点,目前围绕PBDEs的降解研究已有多篇文献报道.
An approximate method is proposed for the solution of a more general class of Cauchy type singular integral equation of the first kind.The present method is illustrated through several examples of sin
We present in this work a numerical study of the square-root formulation which is a stabilization method for computing highly elastic flows of viscoelastic fluids.
In this paper,we report three level implicit method of high accuracy schemes of O(k4+h8),O(k6+h8)and O(k6+h10)for the numerical solution of fourth order non-homogeneous parabolic partial differential
The control of diffusion models is very well developed for uniformly parabolic operators,much less so for degenerate problems.In the latter case,a general theory which covers controllability/observabi
This mini-symposium will present an overview of recent advances on the control of PDEs and stochastic PDEs,as well as their challenging applicative issues for the control of complex models in quantum
