非马尔科夫多值噪声驱动下系统的平均第一通过时间

本文把Weiss等发展的计算平均第一通过时间(简称MFPT)的新方法推广到由非马尔科夫多值噪声驱动的过程.为了简化,本文只限于研究矩形分布这一情形.通过一个重要实例,对MFPT进行了具体计算,并得到了显式解析表示.     

The time interval alignment (IA) policies,boundary and applications with multiple stream arrivals

This paper discusses a class of interval alignment (IA) scheduling policies, which are particularly effective for the systems that do not have Markovian structure. The numerical results show that IA policies effectively smooth part flows, improve performance and decrease average Work-in-Process (WIP) by adding intermediate delays to the system. The boundary of IA policy is proven and the applications of IA policy in the system with multiple stream arrivals have been discussed. With the combination of release policy, it is practical to implement IA to multiple stream arrival system.     

在光子带隙中原子的自发衰减（英文）

研究了一个二能级原子在具有双洛伦兹谱密度的光子带隙中激发态布居的自发衰减动力学行为.通过对比自发衰减动力学行为在马尔科夫近似条件下和非马尔科夫条件下的演化特性,发现了在这两种条件下演化动力学有着明显区别.非马尔科夫记忆效应使得流入环境中的部分信息回复至系统中来,从而导致了原子布居的震荡.另外,研究结果表明耦合强度与衰减率有着密切联系.
