In this paper, we propose a postclustering process that robustly computes cluster regions at different levels of granularity through the complete Order-k Voronoi diagrams. The robustness and flexibility of the proposed method overcome the application-dependency and rigidity of traditional approaches. The proposed cluster tessellation method robustly models monotonic and nonmonotonic cluster growth,...
As witnessed in many recent disastrous events, what-if emergency response is becoming more and more important to prevent hazards, to plan for actions, to quickly respond to minimize losses, and to recover from damages. In this chapter, we propose a complete set of higher order Voronoi diagram-based emergency response system for what-if analysis which is particularly useful in highly dynamic environments...
