A historical running state database-aided stealth attacks (SAs) mitigation approach, aiming to secure distribution grid that relied on nonlinear state estimation model, is proposed. By checking the consistency between traditional nonlinear state estimation outputs and the most likely running states extracted by adaptive neuro-fuzzy inference system (ANFIS) from historical running state database, the...
The explosive growth in both the volume and density of geospatial data, which has resulted in the difficulty of geospatial data mining and knowledge discovery, emphasizes the need for advancing the query, analysis and computation capacity of geospatial database. In addition, distributing applications based on Internet requires geospatial database and data model to accomplish the perpetually increasing...
Compressing the set of frequent sequential patterns is a method in order to address the problem of explosive number of output sequential patterns. In order to get high-quality compression, it first clusters frequent sequential patterns, and then select and output only a representative sequential pattern for each cluster such that the number of these representative sequential patterns is minimized...
