This paper aims to develop a decision rule-based model of household car ownership by using household travel survey data. The rough set approach as one of data mining techniques provides an effective tool to model the presented data set with decision rule sets. In this paper, the outputted “if-then” rules show the significant relationships between car ownership type and household characteristics. The...
The foot is a complex structure, and thus it is difficult to analyse the joint movements in the foot. Few commercial software and models consider the foot as a simple rigid segment and are not adequate to interpret the foot kinematics and kinetics. This study aimed to develop and validate a multi-segment foot model to calculate the joint kinetic and kinematic parameters in the foot during normal gait...
A tuning method for decentralized PI/PID with set-point weighting or 2DOF PI/PID controller is proposed in this paper. The tuning method is based on frequency domain analysis of a decentralized robust controller. In this method, desired dynamic equation (DDE) is designed firstly to meet the control specifications, and then the relation between desired dynamic equation parameters and controller parameters...
In order to extract simple and certain diagnostic rules for wear pattern recognition of diesel engine from incomplete data, a method is proposed to directly extract decision rules for fault diagnosis. After defining the discernibility matrix primitive, the definition of object-oriented discernibility matrix in incomplete decision table for fault diagnosis is also proposed. Using these concepts, the...
