As to problem of time varying delay existing in NCSs, a time-varying model including certain system and uncertain system are constructed firstly, and then stability and stabilization of these systems are discussed based on time-delay system theory, cone convex optimization theory and free weighting matrices approach. Conditions of time-dependent stability and stabilization with less conservative are given in the form of linear matrix inequalities.

This paper mainly discusses a novel non probabilistic convex set method used to estimate the eigenvalue bounds of structures with uncertain parameters.

讨论了在不确定参数的影响下估算结构特征值变化界限的一种新型非概率凸集合方法。

In this paper, interval models in the convex models are used to describe the parameters having uncertain but boundary limits such as stress and load. The shortest distance from coordinate origin to failure surface in the expand space of standardized interval variables is chosen as the non－ probabilistic reliability index.

将具有不确定且有边界限制的应力、载荷等用凸模型中的区间模型来描述，取在标准化区间变量的扩展空间中，从坐标原点到失效面的最短距离作为非概率可靠性指标。

我不愿购物（这可能是源于我不确定的审美判断），但从原则上来说，我喜欢这个国家在商业上的繁荣。

In addition,a negotiation-enabled solution is proposed for the verification with uncertain and incomplete model based on the counter example guided abstract refinement method.

造成不确定的因素，有可能是设计人员缺乏对系统细节的足够了解而无法给出精确的信息，也可能是系统中一些无法预计的行为造成的
