Indexing moving objects is a fundamental issue in spatiotemporal databases. In this paper, we propose an adaptive Lazy-Update Grid-based index (LUGrid, for short) that minimizes th...
When monitoring spatial phenomena, which are often modeled as Gaussian Processes (GPs), choosing sensor locations is a fundamental task. A common strategy is to place sensors at t...
Bounded parameter Markov Decision Processes (BMDPs) address the issue of dealing with uncertainty in the parameters of a Markov Decision Process (MDP). Unlike the case of an MDP, t...
In computer security, many researches have tackled on the possibility of a unified model of access control, which could enforce any access control policies within a single unified...

A sharing community prospers when participation and contribution are both high. We suggest both, while being related decisions every peer makes, should be given separate rational ...
