We sketch how to express typical features of agent communication protocols in a simple temporal logic and show that conformance verification at runtime reduces to a generalised f...
Given a set P of n points in convex position in the plane, we prove that there exists a point p ∈ P such that the number of distinct distances from p is at least (13n−6)/36 . ...
This paper studies security for data aggregation in sensor networks. Current aggregation schemes were designed without security in mind and there are easy attacks against them. We...
Abstract. This paper presents a general framework to segment curvilinear objects in 2D images. A pre-processing step relies on mathematical morphology to obtain a connected line wh...
—Motivated by the migration mechanisms of ecosystems, various extensions to biogeography-based optimization (BBO) are proposed. BBO is an original optimization method based on th...
