The Research of Mining the Mutative Knowledge With Extension Data Mining

Chen Wenwei

Strategic Study of CAE 2006, Volume 8, Issue 11, Pages 70-73

Abstract:

The thesis standardized the extension information and the extension knowledge, that is, basing onknowledge, the thesis extended the mutative information and knowledge, and nailed down the conceptions of extensiondata mining and extension reasoning.This thesis also attested two theorems of the extension data mining and the formula of the extensionThe author put forward the extension data mining which extended from mining the static knowledge to mining

Extension Controller Design via Sliding Mode Control

Chen Jenyang,Wong Chingchang

Strategic Study of CAE 2001, Volume 3, Issue 9, Pages 48-51

Abstract:

In this paper, a novel extension controller based on the scheme of sliding mode control is investigatedBy integrating the essential concept of extension set theory with the sliding mode control , the robustextension controller can be easily realized.In this study, a basic extension controller is organized first without any specific expert knowledgeActually, the proposed extension controller is stable in the sense of the Lyapunov.

Keywords： extension set extension control sliding mode control system stability

Correlation between tension softening relation and crack extension resistance in concrete

Xiufang ZHANG , Shilang XU ,

Frontiers of Structural and Civil Engineering 2009, Volume 3, Issue 3, Pages 323-329 doi: 10.1007/s11709-009-0041-2

Abstract: Changes of the material fracture energy consumption with crack propagation can be described by a crack extensionThe variation of the crack extension resistance is mainly associated with the energy consumption in theThe crack extension resistance is then a function of the softening curve, which is a basic mechanicalThe relationship between the softening curve and the crack extension resistance curve is then analyzedThe results indicate that the characteristic points of the crack extension resistance curve is closely

Adaptive Extension Controller Design for Nonlinear Systems

Wong Qingchang,Chen Zhenyuan

Strategic Study of CAE 2001, Volume 3, Issue 7, Pages 54-58

Abstract:

A design method for the extension controller is developed in this paper.The proposed adaptive extension control resulting from the direct adaptive approach is employed to directlyadapt the gain parameter of the extension controller.Unlike the fuzzy controller, only one linguistic — like level is needed in the extension controllerThe derivation shows that the proposed extension controller is stable in the sense of the Lyapunov.

Study on Incompatibility Problems SolvingBased on Extension Theory

Yang Chunyan

Strategic Study of CAE 2007, Volume 9, Issue 10, Pages 36-39

Abstract:

Based on the study of single-characteristic incompatibility problem and the transformation of solving it, the structure, judging methods and solving methods of multi-characteristic incompatibility problem are studied. The transformation for solving incompatibility problem is called solution transformation. Its applied value will be explained through its application in marketing. This study will provide new tools for the intelligent disposal of contradiction problem.
