A cone can help you find your way in a Poisson Delaunay triangulation

Walking strategies are a standard tool for point location in a triangulation of size n. Although often claimed to be Θ( √ n ) under random distribution hypotheses, this conjecture has only been formally proved by Devroye, Lemaire, and Moreau [Comp Geom–Theor Appl, vol. 29, 2004], in the case of the so called straight walk which has the very specific property that deciding whether a given (Delau...

Can you Trust your Data?

A new program analysis is presented, and two compile time methods for this analysis are given. The analysis attempts to answer the question: “Given some trustworthy and some untrustworthy input, can we trust the value of a given variable after execution of some code”. The analyses are based on an abstract interpretation framework and a constraint generation framework respectively. The analyses ...

Can Social Tags Help You Find What You Want?

One of the uses of social tagging is to associate freely selected terms (tags) to resources for sharing resources among tag consumers. This enables tag consumers to locate new resources through the collective intelligence of other tag creators, and offers a new avenue for resource discovery. This paper investigates the effectiveness of tags as resource descriptors determined through the use of ...

Constraint Acquisition - You Can Chase but You Cannot Find

We identify established tableaux techniques as an invaluable tool for semantic knowledge acquisition in the design process of relational databases. Sample databases allow users and designers to judge, justify, convey and test their understanding of the semantics of the future database. In the case of integrity constraints such sample data can provide considerable assistance for deciding whether...
