Both expert system and data mining belong to the Artificial Intelligence fields. Association rule is a method of datamining, whose typical application is analyzing the shopping basket in supermarket. The main task of expert system is ratiocination, while that of association rule is to find out the valuable relationship between each data item. By modifying the apriori arithmetic and the method of the making rules, we mine the decisive rule of database that could be applied in expert system, thereby find out the method of mining decisive rule using association rules.

The purpose of image fusion is to merge complementary information from multi-sensor data for visual perception so as to improve the visual perception of the image. This paper proposed an image fusion method based on B-spline gradient. It first divided the source images into the small blocks of size, calculated separately the B-spline gradient of the corresponding small block, added up the gradient module values, calculated the weighted value of each small block gradient module value, each small block multiplied with its respective weighted value, and finally obtained the fusion image small block. This paper finally produced the experiments and results show that, this proposed method is effective and seems to be a better performance than traditional principal component analysis, wavelet transform and Laplacian pyramid.

Firstly equivalence between Pi calculus and Artificial Neural Networks (ANN) is illustrated;furthermore a scheme for using Pi calculus to model ANN is presented. On the basis of them, then a classification based on Pi calculus, which uses the same basic principles of concurrent computation as neural networks, is discussed. Finally its superiority is also discussed.

Measuring post dialysis urea rebound (PDUR) requires a 30- or 60-minute post-dialysis sampling, which is inconvenient. This paper presents a novel technique for predicting equilibrated urea concentration and post dialysis urea rebound in the form of a Takagi-Sugeno-Kang fuzzy inference system. The advantage of this neuro-fuzzy hybrid approach is that it doesn't require 30-60-minute post-dialysis urea sample. Adaptive neuro-fuzzy inference system (ANFIS) was constructed to predict equilibrated urea (C eq ) taken at 60 min after the end of the hemodialysis (HD) session in order to predict PDUR. The accuracy of the ANFIS was prospectively compared with other traditional methods for predicting equilibrated urea (C eq ), PDUR and equilibrated dialysis dose (e q Kt/V). The results are highly promising, and a comparative analysis suggests that the proposed modeling approach outperforms artificial neural networks and other traditional urea kinetic models (UKM).

A concept of functional dependency in XML documents based on constraint-tree is proposed. The definition proposed in this paper captures the tree-structured characteristics of XML documents in structure and considers a more general situation of XML functional dependencies based on sub-trees with some constraint conditions in XML documents, which overcomes the shortcomings of related definitions of XML functional dependencies. The relationship between XML functional dependencies and XML keys are also discussed.

This paper describes an assignment to non-computerscience majors aimed at improving students' password selection and management practices. The study analyzes student passwords based on an anonymous questionnaire. Results indicate the majority of students either had changed or plan to change their passwords following the assignment to meet good password guidelines. The analysis revealed three guidelines that were not being followed that need additional emphasis when presenting good password guidelines: not using personal information in passwords, frequently changing to a new password, and using a mix of lower and upper case letters, numbers and special characters.

XML functional dependencies are very important semantic information of XML dataset. It is important to find the functional dependencies from the known functional dependencies in XML dataset. As in relational database, a set of inference rules of XML functional dependencies is needed to do such work. This paper proposes a set of inference rules of XML functional dependencies. The main contribution and difference with earlier related work is that we studies the problem based on a new concept of XML functional dependency, i.e. constraint-tree model is used in defining such XML functional dependency. It has the improvement over related definitions in the following aspects: (1) It captures the tree-structured characteristics of XML documents in structure. (2) It considers a more general situation of XML functional dependencies based on sub-trees with some constraint conditions in XML documents.
