Matching and evaluation of disjunctive predicates for data stream sharing
New optimization techniques, e. g., in data stream management systems (DSMSs), make the treatment of disjunctive predicates a necessity. In this paper, we introduce and compare me...

Sketch Map Analysis Using GIS Buffer Operation
We developed a method to analyze sketch maps by GIS, and applied it to an actual case study. We found that analysis using buffer operation was more effective for sketch map analyse...
