Nowadays, more and more databases are distributed in networks. To produce knowledge with the databases, traditional data mining technology should be developed in model, algorithm, strategy, etc. The popular distributed data mining (DDM) systems are introduced and classified into three classes: DDM systems based on parallel data mining agents, DDM systems based on meta-learning, and DDM systems based...
The existing empirical study of Internet shopping in literature, mostly concerned about the interaction relationship of retailer and customer, few scholars study the process of transactions between customers and other services suppliers, by assaying the main body as a system. This paper establishes Internet shopping stakeholders' transaction model through the entire transaction process analysis. The...
A new method of constructing customer satisfaction (CS) analysis model is proposed in detail. Based on statistical analysis, reliability analysis, validity analysis and factor analysis of sample data, the hierarchical model of customer satisfaction analysis is designed using the theory of hierarchical rule structure. In such model, the customer satisfaction analysis system is partitioned into seven...
Failure modes and effects analysis (FMEA) and fault tree analysis (FTA) are two effective fault analysis technologies and the integration of them is also applied widely in many industry domains. But when they are used for fault diagnosis, the ability of inference is not very enough and especially they are not suitable to use the fault related symptoms to do some posterior inference. To solve this...
How to improve the reusability of testing environment is a key problem to be solved in embedded software testing field. In this paper, the framework technology is introduced into the construction of embedded software testing environment firstly. And then, the micro-core plug-in framework is used as the design basis of embedded software testing development environment framework (ESTDEF). Furthermore,...
In order to suppress the torsional vibration of rotary machine, a PI controller was analytically derived based on stability of the closed-loop system and Hinfin mixed sensitivity function. This novel design procedure is adapted to some unstable and critically stable systems, and a single parameter T1 is included in the controller, which can be determined by the disturbance rejection capability and...
A triangular mesh model matching method by combination of principle component analysis (PCA) and ICP algorithm is presented. Firstly, two 3D models are initially located by using PCA method. Secondly, ICP algorithm is applied to do fine adjustment and calibration. Finally, quantitatively evaluate the similarity between two models by using difference sum of squares function. This kind of two-stage...
For solving measurement problem of spanless points of complex rotary mechanical drive system, a new torsional vibration measuring model of spanless points was proposed by using continuous shaft segment model. The measuring model could calculate torsional vibration parameter values of spanless points utilizing testing data of measurable points. The correctness of theory was verified by torque testing...
