Object identification via a perceptual-demonstrative mode of presentation has been studied in cognitive science as a particularly direct and context-dependent means of identifying objects. Several recent works in cognitive science have attempted to clarify the relation between attention, demonstrative identification and context exploration. Assuming a distinction between ‘(language-based) demon...

The content of many communication services depends on the context, such as the user’s location. We describe a ’service’ URN that allows to identify context-dependent services that can be resolved in a distributed manner.

This paper presents part of an on-going project to integrate perception, attention, drives, emotions, behavior arbitration, and expressive acts for a robot designed to interact socially with humans. We present the design of a visual attention system based on a model of human visual search behavior from Wolfe (1994). The attention system integrates perceptions (motion detection, color saliency, ...

We address the problem of computing homotopic shortest paths in presence of obstacles in the plane. The problems on homotopy of the paths received attention very recently [3, 8]. We present two output-sensitive algorithms, for simple paths and non-simple paths. The algorithm for simple paths improves the previous algorithm [8]. The algorithm for non-simple paths achieves O(log n) time per outpu...

Nowadays, lots of service providers offer predictive services that show in advance a condition or occurrence about the future. As a consequence, it becomes necessary for service customers to select the predictive service that best satisfies their needs. The QuPreSS reference model provides a standard solution for the selection of predictive services based on the quality of their predictions. Qu...

Intelligent, context sensitive content assist (also known as code completion) plays an important role in the effectiveness of model editors. This is not only true for textual language notations, but also for graphical notations that often contain a significant amount of textual elements. This paper presents techniques to describe content assists for meta-model based textual model editors. We sh...

Based on an approach of AAentranger&Schneider we give an asymptotic formula for the expected number of k-faces of the orthogonal projection of a regular n-crosspolytope onto a randomly chosen isotopic subspace of xed dimension, as n tends to innnity. In particular , we present a precise asymptotic formula for the (spherical) volume of spherical regular simplices, which generalizes Daniel's form...

In a free recall experiment, divers learnt lists of words in two natural environments: on dry land and underwater, and recalled the words in either the environment of original learning, or in the alternative environment. Lists learnt underwater were best recalled underwater, and vice versa. A subsequent experiment shows that the disruption of moving from one environment to the other was unlikel...

A novel photonic crystal lattice is proposed for trapping a two-dimensional array of particles. The lattice is created by introducing a rectangular slot in each unit cell of the Suzuki-Phase lattice to enhance the light confinement of guided resonance modes. Large quality factors on the order of 10⁵ are predicted in the lattice. A significant decrease of the optical power required for optical t...
