计算机科学 , 2009,
Abstract: By analyzing thoroughly the essential relation between two input variables of the normal two-dimensional fuzzy controller,this paper proved that the essential relation is just universal combinatorial relation in Universal Logic.So the simple universal combinatorial operation can be used instead of complex fuzzy reasoning process.As a result,a flexible logic control method was proposed to realize the accurate control for complex system.Finally,the experimental result of single inverted-pendulum physical syst...

Abstract: 基于线性特征测度的定义,本文详细地讨论了模糊推理中零级泛蕴涵满足信息有界性原则的条件,并得出结论:当命题间是相克相关,即其广义相关系数h∈0,0.5]时,零级泛蕴涵满足信息有界性原则。这一结论对于在实际控制应用中,如何给定命题间的广义相关系数h值具有重要的指导意义。

计算机科学 , 2009,
Abstract: In practical complex system,every factor is generally with unequal weight.But the existing universal combinatorial operation only discusses an ideal state that every factor is with equal weight.This paper gave two kinds of gene-ral weighted operators.Based on the operators given,an unequal weights universal combinatorial operation model was proposed.
Research on the Incompatible Factor of Fuzzy Reasoning

计算机科学 , 2004,
Abstract: The "incompatible factor" concept is introduced for the first time,and the Triple 1 method is improved with the thinking. The reason of why the new method should be more reasonable than the Triple I method is analyzed, then the new method is generalized by considering two different types of implication operations.
3-[(E)-1-(Benzyloxyimino)ethyl]-7-(3-methylbut-2-enyloxy)-2H-chromen-2-one
Hui Wang,Li-juan He,Wei-hua Zheng,Hua-can Song
Acta Crystallographica Section E , 2011, DOI: 10.1107/s1600536811019015
Abstract: In the title compound, C23H23NO4, the dihedral angle beween the chromen-2-one ring system and the benzene ring is 69.73 (10)° and the molecule adopts an E conformation with respect to the C=N double bond. In the crystal, inversion dimers linked by pairs of C—H...O hydrogen bonds occur, generating R22(12) loops.
Modeling Mental States of Social Agent
社会Agent的思维模型

计算机应用研究 , 2005,
Abstract: The research about sociality of Agents usually bases on two ideas: arguing the sociality on social level, or social mental model being joined in BDI. However, an Agent always bring into play his functions by taking on roles, and once he holds a role, he acts as the role by adopting role-based mental att ributes in the structure of social relationship of the role. Drawing this idea, the model of role-based social mentality is proposed and some social concepts including relationships, obligations and commitments are hold in the category o f roles.

控制理论与应用 , 2001,
Abstract: This paper proposes a new T-norm and S-norm, which can vary through Lukasiewicz operators, Probability operators, and Zadeh operators with a correlation coefficient \%h\% changing from -1 to 1.Then we present simplified operators for multi input AND and OR operators to be used in fuzzy logic controller, replacing the conventional MAX/MIN operators. We use genetic algorithm to decide the correlation coefficients. Simulation results show that our approach is better than the conventional fuzzy logic controller.

计算机科学 , 2006,
Abstract: As a typical nonlinear, multi-value, high-order, strong-coupling and naturally instable complicated system, multi-order inverted pendulum is always the ideal research platform. During half a century, many organizations have done lots of works and accumulated many materials. In this paper, the stable control research status of multi-order inverted pendulum is summarized, and the development trend is discussed. The main control methods include linear control, predictive control and intelligent control, and intelligent control which includes fuzzy control, human-imitating control, computing intelligent control and cloud-model control ete. and is the mainstream. The development trend is the research of all kinds of intelligent control methods and the applications of the combination of these methods. control

计算机科学 , 2005,
Abstract: The study of implication operator is important and difficult in the study of logic. In this paper, using the principle of the universal logics, generalized correlation is introduced into Interval-valued Logics, the intersection, u- nion and complement operation are redefined, and a new kind definition of the Interval-implication is given. The oper- ation models of the Interval-valued Logics are changeable continuity. Regularity and monotonicity of interval-implica- tion are proved, the property of adjoint pair of interval intersection and implication is also proved. The operation models of the Interval-Logics are firstly given for intersection, union and implication in the special points of h. It is very important to the further study of making Interval-Logics flexible.
