Two schemes for computing moments of free-form objects are developed and analyzed. In the ®rst scheme, we assume that the boundary of the analyzed object is represented using parametric surfaces. In the second scheme, we represent the boundary of the object as a constant set of a trivariate function. These schemes rely on a pre-computation step which allows fast re-evaluation of the moments whe...

We first give an overview of Interactive Communication Management (ICM), and especially feedback, in humanhuman communication. We then select a limited range of ICM behaviour useful for dialogue systems, and show how these utterances and responses to them are managed in a dialogue system implementing a theory of issue-based dialogue management.

In this paper, we propose an interactive motion synthesis technique that synthesizes a continuous motion sequence from given elementary motions. A user can either specify the execution timings of motions, or execute motions in a sequence with automatically determined execution timings. Our method is based on a previous approach that determined the appropriate synthesis method and blending range...

Purpose – The purpose of this paper is to examine funding models for Open Access (OA) digital data repositories whose costs are not wholly core funded. Whilst such repositories are free to access, they are not without significant cost to build and maintain and the lack of both full core costs and a direct funding stream through payment-for-use poses a considerable financial challenge, placing t...

Various classes of algebraic surfaces have been examined as to their suitability for CAGD purposes. This paper contributes further to the study of a class of quartic surfaces recently investigated by Degen, having strong potential for use in blending, and possibly also in free-form surface design. These surfaces are here put in the context of a classi cation of quartic surfaces originally given...

We present an account of a process by which different conceptualisations of number can be blended together to form new conceptualisations via recognition of common features, and judicious combination of their distinctive features. The accounts of number are based on Lakoff and Núñez’s cognitively based grounding metaphors for arithmetic. The approach incorporates elements of analogical inferenc...

This paper presents a new interpretation of the general definition of the binary blending operator of implicit modeling. Instead of considering the operator as a composition of potential functions or as a function defined in the combined primitives metric, we propose to consider it as an implicit curve extruded in an implicit extrusion field. An implicit extrusion field is a 2D space for which ...

We present a computational framework for chord invention based on a cognitive-theoretic perspective on conceptual blending. The framework builds on algebraic specifications, and solves two musicological problems. It automatically finds transitions between chord progressions of different keys or idioms, and it substitutes chords in a chord progression by other chords of a similar function, as a ...

I briefly review the experimental observations concerning the charmed mesons D * sJ (2317), D sJ (2460) and survey on some of the interpretations proposed in order to understand their nature. I present an analysis of their decay modes in the hypothesis that they can be identified with the scalar and axial vector s P ℓ = 1 2 + states of c¯ s spectrum (D * s0 , D ′ s1). The method is based on hea...
