The quality and availability of positional information (location, orientation) is a key resource that strongly influences the way in which ambient services can be provided to nomadic users. In this article, we propose a number of mechanisms that tackle resource restrictions related to positional information on two levels, the application level and the positioning level. We introduce a generic m...

In F-logic and RIF, objects (frames) are de ned entirely separately from function and predicate applications. In POSL and RuleML, these fundamental notions are integrated by permitting applications with optional object identi ers and, orthogonally, arguments that are positional or slotted. The resulting positional-slotted, object-applicative (psoa) terms are given a novel formalization, reducin...

Different voting systems can lead to different election outcomes even when voter preferences are held constant. Using the 1992 election as an example, it is shown how the outcome of every positional vote system can be found. Similarly, every possible cumulative and approval vote outcome is shown. Multiple vote systems, like approval and cumulative voting, have disturbing properties. Using the 1...

benign paroxysmal positional vertigo (bppv) is a condition that indicates a benign inner ear disorder. it is generally believed that bppv is due to the dislodged otoconial particles from otolith organs and unusual collection of them within any of semicircular canals or even in all three semicircular canals. although the typical features of nystagmus in bppv have been well-studied, very few stud...

We study positional voting rules when candidates and voters are embedded in a common metric space, and cardinal preferences are naturally given by distances in the metric space. In a positional voting rule, each candidate receives a score from each ballot based on the ballot’s rank order; the candidate with the highest total score wins the election. The cost of a candidate is his sum of distanc...
