可信计算环境证明方法研究

首先分析了可信计算环境下多远程证明实例执行的动态性、并发性、一致性等问题,提出了一个完整的可信计算环境多远程证明实例动态更新证明方案,以保证通信双方终端计算环境的可信.然后阐述了主要由计算环境组件度量算法、会话组件树计算算法和多远程证明实例证明协议组成可信计算环境证明方法.最后对该证明方法的安全性和效率进行分析,并构建原型系统论证证明方案的可行性和高性能.

好校长从哪里来

有人说,要办好一所学校,仅仅靠一把手是不够的,而要毁掉一所学校,仅仅靠一把手就够了。虽然此话有些偏激,但无数实例证明校长是一所学校灵魂一般的存在,具有至关重要的意义。好校长如此重要,那好校长从哪里来呢?笔者作为一个从事农村教育22年、有祖国西北和南方两地10多年校长经历的教育人,有自己切身的体会。

合作原则和礼貌原则的运用——以《十三邀》为例

文章介绍了合作原则和礼貌原则的内涵,以《十三邀》为例,分析了合作原则和礼貌原则在会话中的运用,遵循原则产生的效果和违背原则产生的效果以及合作原则和礼貌原则之间的关系。用实例证明,并非违背合作原则的同时都遵循了礼貌原则,并且提出一种假设,解释了合作原则和违背合作原则在人们头脑中的认识。

Similarity measure design on overlapped and non-overlapped data

Similarity measure design on non-overlapped data was carried out and compared with the case of overlapped data.Unconsistant feature of similarity on overlapped data to non-overlapped data was provided by example.By the artificial data illustration,it was proved that the conventional similarity measure was not proper to calculate the similarity measure of the non-overlapped case.To overcome the unbalance problem,similarity measure on non-overlapped data was obtained by considering neighbor information.Hence,different approaches to design similarity measure were proposed and proved by consideration of neighbor information.With the example of artificial data,similarity measure calculation was carried out.Similarity measure extension to intuitionistic fuzzy sets(IFSs)containing uncertainty named hesitance was also followed.

如果相互依存不可靠

重读Kenneth Waltz的《国际政治理论》。在这本40年前的结构现实主义经典中,他认为,经济全球化时代国家间相互依存度上升,并不会约束大国之间的权力竞争。其实,经济高度相互依存并不足以防止国家间冲突这件事本身,早有实例证明。
