查询词典 interval algebra

In this paper, we discuss effect algebra and related topics. The main results are the following:1. Effect algebra is a commutative algebraic structure. To get a non-commutative algebraic structure.we introduced the concepts of left difference and right difference, and we also introduced the concept of the Bi-difference sets, the concept of pseudo-difference poset, and proved that pseudo-difference poset is equivalent to pseudo-effect algebra.

效应代数描述的是具有交换性的量子系统，我们借助于差运算的思想研究了不可交换的量子逻辑结构，建立了左差、右差、伪差偏序集、双差集等概念，证明了伪差偏序集与伪效应代数等价，并得到了双差集的幺半群表示定理。

In third part, I discussed R0 algebra in two different aspect:(1) Defined Boole element in R0 algebra. Gave the properties of Boole element and distributive rules of Boole element about finite R0 algebra. Study the filter and the stone filter of L are filters of M.

元的分布规律：研究了民代数M的滤子和民代数M作为有界分配格（记这个有界分配格为L（MO 的滤子之间的关系，得出结论：L的极小素滤子以及 L的 Stone滤子都是 M的滤子，但 L的滤子一般不必是M的滤子。

Uncertain temporal relations can be represented and reasoned by IA. IA has strong expressive ability in tense, and it can represent all natural temporal relations. At the same time, temporal relation represented by IA is highly visual and comprehensive. In additional, IA has been extended from one-dimension temporal area to two-dimension spatial area, that is to say, interval algebra can be developed to rectangle algebra for two-dimension reasoning.

用区间代数能表示不确定的时态关系，可以很方便地用于时态推理，表达能力强；时态关系的区间表示比较直观，可理解性强；同时区间代数可以进一步扩展到二维空间领域，即将区间代数拓展为矩阵代数，实现二维空间推理。

In the temporal reasoning, if interval algebra is combined with interval matrix, the computing efficiency is improved, and the temporal representation keeps visual and comprehensive as well.

在一维时态推理中，将时态的区间表示和矩阵表示相结合，在提高计算效率的同时，保持了形象直观的时态表示。

By describing trusty degree of information through membership function defined on the tuple, they broaden relation algebra of general meaning, add an attribute function to every tuple, define meaning of fuzzy attribute, express similar degree in the interval of fuzzy object and entity with semanteme distance in the interval of tuple, and also studys the fuzzy relation operating.

通过定义在元组上的隶属函数反映信息的可信度，对通常意义下的关系代数进行了扩展，每一元组都附一属性函数，定义了模糊属性的含义，用元组间的语义距离表示模糊对象和实体间的相似度，并对该意义下的关系操作进行了相应的研究和讨论。

Based on the modified interval algebra, an interval based temporal logic TL is constructed, its semantics is rigorously defined.

在扩充后的时区代数结构的基础上，构造一种基于时区的一阶时态逻辑语言TL，并为TL规定了语义。

In chapter four, by the concept of negative definite of symmetry interval matrix, methods of analysis of interval matrix and the method of Lyapunov function, the robust absolute stability of Lurie control system with multiple nonlinearities was investigated, and some algebraic sufficient conditions in the form of inequalities of interval matrix were obtained.

In this paper,we propose a concept called interval implicitization of rational bézier surfaces,that is ,finding an interval algebraic surface with lower degree which bounds a given parametric rational bézier surface such that some objective function involving the width and the tention term of the interval algebraic surface is minimized.

本文提出有理Bézier曲面的区间隐式化的概念，即找到一条较低次的区间代数曲面使得给出的有理Bézier曲面落在该区间代数曲面内，并使得一包含区间代数曲面的宽度和张量项的目标函数达到最小。

The interval estimation information given by estimators is classfied. The bargaining interval and bargaining value is also determined for each class information. Then, the information of the bargaining interval and bargaining value is integrated by utilizing the induced ordered weighted averaging operator. The problem to choice the weighted vector of the IOWA operator is also discussed.
