We propose a new method, called closed multi-dimensional sequential pattern mining, for mining multidimensional sequential patterns. The new method is an integration of closed sequential pattern mining and closed itemset pattern mining. Based on this method, we show that (1) the number of complete closed multidimensional sequential patterns is not larger(More)
The use of multiple independent spanning trees (ISTs) for data broadcasting in networks provides a number of advantages , including the increase of fault-tolerance and bandwidth. Thus, the designs of multiple ISTs on several classes of networks have been widely investigated. Tang et al. studied the problem of constructing k ISTs on k-dimensional hypercube Q(More)
Design patterns are graceful solutions to specific software design problems. However, choosing proper design patterns for given software design problems might not be an easy task especially for novice developers. The design patterns searching tools are therefore needed to solve the problem. One major problem of the existing researches in this field is the(More)
Web Services have been widely adopted in business projects, and almost all Web Service developers agree that security factors are the principal components that must be taken into consideration. A large number of security metrics and measurements is available for specific business needs, and the best practice for different business demands is therefore(More)
This study investigated the use of Artificial Neural Network (ANN) and Genetic Algorithm (GA) for prediction of Thailand's SET50 index trend. ANN is a widely accepted machine learning method that uses past data to predict future trend, while GA is an algorithm that can find better subsets of input variables for importing into ANN, hence enabling more(More)
