This paper presents the current status of the research in the Higgins project and provides background for a demonstration of the spoken dialogue system implemented within the project. The project represents the latest development in the ongoing dialogue systems research at KTH. The practical goal of the project is to build collaborative conversational dialogue systems in which research issues s...

This paper gives a new method for image rectification, the process of resampling pairs of stereo images taken from widely differing viewpoints in order to produce a pair of “matched epipolar projections”. These are projections in which the epipolar lines run parallel with the x-axis and consequently, disparities between the images are in the x-direction only. The method is based on an examinati...

Adaptive phenotypic flexibility occurs in many traits in many different organisms and has profound evolutionary consequences (West-Eberhard 2006). Spider orb-web construction behavior exemplifies complex, highly stereotyped, relatively innate behavior whose details can nevertheless be adjusted to some extent to local conditions (Witt et al. 1968; Vollrath 1992; Heiling & Herberstein 2000), and ...

We use the n-globe with its skeletal filtration to define the fundamental globular ω–groupoid of a filtered space; the proofs use an analogous fundamental cubical ω–groupoid due to the author and Philip Higgins. This method also relates the construction to the fundamental crossed complex of a filtered space, and this relation allows the proof that the crossed complex associated to the free glob...

"Countries," nations, nation-states, and national economies are in fact collections of spaces (regions), each with its own society and its own economic, social, political and power structure. The degree to which these spaces are integrated into a unified national economic, social, political and administrative system varies a great deal from country to country, and these variations go a long way...
