In order to recommend the combined e-learning resources to a learner according to his objective and knowledge background automatically and dynamically, an e-learning process model was presented. The directed-hyper graph was used to model the process which connected the learner, the knowledge and the learning resources. The structure of an e-learning process, the personalized resource requirement corresponding...
According to the surrounding rock stability type determined through fuzzy comprehensive evaluation, bolt and cable support parameters for thick soft coal roadway were selected based on the engineering analogy method. Considering two conditions that the roadway was arranged along the roof and along the floor, the activity law of the roadway surrounding rock was simulated through Fast Lagrangian Analysis...
In order to solve the modern logistics problem of vehicle distribution, a particle swarm optimization (PSO) algorithm based on clustering analysis is proposed in this paper. This algorithm clusters the target points in need of distribution primarily by DBSCAN algorithm, and then weighted k-means algorithm is used to cluster the target points finally based on the primary clustering. Corresponding vehicles...
In order to provide a transaction environment of more security for e-commerce system, a novel intrusion detection system (IDS) based on the system call sequences is proposed in this paper. Firstly, this system improves the basic short sequence matching model combined with consistency principle of process initialization to emphasize on detecting system call sequences when process is initializing. Secondly,...
