Target tracking performance is heavily dependent on a good blend of vision algorithm and control. Because of performance and computational complexity,...

Consistent Fuzzy Linguistic Preference Relations for Computer Integrated Manufactory Systems Selection

Tien-Chin Wang, Yueh-Hsiang Chen
Most decision-making and problem-solving tasks are too complex to be understood quantitatively. People perform such tasks using knowledge that is imprecise rather than precise. This study presents consistent fuzzy linguistic preference relations rather than fuzzy analytic hierarchy process (FAHP) to...

Fuzzy Logic for Developments and Applications of Unbalance Three-Phase Fuzzy Feeder Models

Shyi-Wen Wang
Based on the fuzzy set theory, this study introduces three novel three-phase fuzzy feeder models for fast distribution system calculations. These fuzzy models are formulated using three lumped individual phase loads to represent single-phase, three-phase unbalanced, and nonuniformly distributed loads...

High-Speed Fuzzy Inference Processor Using Active Rules Identification

Shih-Hsu Huang, Shi-Zhi Liu, Yi-Rung Chen, Jian-Yuan Lai
Once the input values are given, the active rules in a fuzzy inference execution have been determined. Based on the observation, our approach is to identify the active rules before fuzzy inference execution. To achieve this goal, our architecture provides the following two mechanisms: (1) a mechanism...

Application of Inverse Fuzzy Logical Inference to Breakdown Diagnosis

Jeng-Jong Lin
In this paper, we present a search model, which divide symptoms into two sets, i.e., the positive symptom set (J1) and the negative symptom set (J2), to eliminate the causes of low possibility in the cause set to more effectively find various possible breakdown causes occurred during spinning process....

Axiomatization of fuzzy attribute logic over complete residuated lattices

Radim Belohlavek, Vilem Vychodil
The paper deals with fuzzy attribute logic (FAL) and shows its completeness over all complete residuated lattices. FAL is a calculus for reasoning with if-then rules describing particular attribute dependencies in object-attribute data. Completeness is proved in two versions: classical-style completeness...

Pavelka-style fuzzy logic for attribute implications

Radim Belohlavek, Vilem Vychodil
We present Pavelka-style fuzzy logic for reasoning about attribute implications, i.e. formulas $A\Rightarrow B$. Fuzzy attribute implications allow for two different interpretations, namely, in data tables with graded (fuzzy) attributes and in data tables over domains with similarity relations. The axioms...

On Tensions and Causes for School Dropouts åÁV An Induced Linked Fuzzy Relational Mapping (ILFRM) Analysis

Joseph Arul, Nathan Pathi, Thirusangu K, Mary John
The teachers and the school authorities often call the parents in connection with a child’s ‘performance’ in school. The children have to face the wrath of both the parents and the teachers. This tension slowly builds up and the child decides to quit the school forever. This paper analyzes the causes...

Power Signal Predictions by Several Neural Models

Rey-Chue Hwang, Yu-Ju Chen, Shang-Jen Chuang, Hunag-Chu Huang, Chuo-Yean Chang
In this paper, a comparison study for the non-stationary power signal prediction by using several neural models is presented. A reliable and accurate neural forecasting model is trying to be found and concluded. This study is expected to provide some suggestions and could be treated as a reference for...
