This paper is concerned with uniform measure attractors for non-autonomous stochastic evolution systems. We first introduce the concept of uniform measure attractor and then provide a sufficient criterion for existence and uniqueness of such attractors. As an application, we prove the existence and uniqueness of uniform measure attractors for the stochastic Navier-Stokes equations with deterministic almost-periodic forcing and nonlinear diffusion terms.

介绍了典型的信息物理融合系统(cyber-physical system,CPS)结构,该类系统将物理过程、嵌入式计算、网络融合于一体,具有异构、并发、状态随时间演化等特性,这些特性对系统的设计提出了很高的要求。基于模型的方法是设计CPS系统的有效途径,给出了CPS系统的典型结构,对单自由度系统的有阻尼自由振动、自动挡汽车换挡以及交通路口红绿灯控制3个系统的模型问题进行了分析,指出CPS中的连续动态行为可用基于时间的微分方程来建模,混合系统行为可用模态模式进行建模,对于一些状态比较复杂的系统则可通过对状态机的组合进行建模。在此基础上应用Ptolemy对以上3个系统进行了建模并给出了仿真结果,为CPS系统设计提供了基础。

把具有不同重要性的功能集成到一个共享平台上的混合关键级系统,是当前嵌入式系统发展的主要趋势之一.已有的混合关键级调度理论为了保证高关键级作业的完成,大多不支持关键级向下切换,在系统进入高关键级后直接放弃低关键级作业的执行,这对系统中作业集的整体完成率有负面影响.为了应对这一问题,把需求边界分析理论扩展到混合关键级作业系统中,提出了作业的动态需求边界函数,以矢量的形式记录系统在运行时需求边界函数的动态变化,并相应地提出了作业的混合关键级松弛时间与系统关键级松弛时间的概念.在此基础上,提出了一种基于动态需求边界的混合关键级作业调度算法CSDDB(criticality switch based on dynamical demand boundary).该算法选择具有最小松弛时间的关键级作为执行关键级,在保证高关键级作业可调度的情况下,充分利用系统资源,尽可能地满足低关键级作业的执行.应用随机生成的任务集进行仿真实验,结果表明,与已有算法相比,CSDDB在系统关键级的保证与作业集整体完成率方面比现有算法有10%以上的提升.
