An elementary account on the chaoticity of galactic world-lines in an open universe is given. A new type of cosmic evolution by global metrical deformations, unpredicted by Einstein’s equations, is pointed out. Physical effects of this evolution are backscattering of electromagnetic fields and particle creation in quantum fields. We review in an untechnical way how global metrical deformations ...

This paper is dedicated to the study of metrical properties of a collection of 2D thinning algorithms that we have proposed. Here, we characterize their underlying metrics and use it to reduce the classical metrical biases that affect thinning algorithms in the square grid. We show that some algorithms from the collection lead to skeletons based on a particular geometry, corresponding to the (4...

Objective measures of musical tempo are linked to a particular metrical pulse, and this is most likely true for subjective tempo as well. Therefore, tapping along with a rhythm should be predictive of relative tempo judgments. The difficulty of such judgments may lie in the choice of a particular metrical level as the referent. Multiple levels may compete and create ambiguity. Analogies are dra...

The article by Daelemans et al. bears on an important question about the adequacy of the "Principles and Parameters" framework as the basis of a process account of language learning (exemplified, for instance, by the work of Dresher and Kaye 1990). As Gupta and Touretzky (1991, 1994) have pointed out, a learning system based on a particular linguistic description (of metrical phenomena, for exa...

One of the problems that must be addressed by a textto-speech system is the derivation of pitch accent, marking the distinction between "given" and "new" information in an ut terance. This paper discusses a languageindependent approach to this problem, which is based on focus-accent theory (e.g. Ladd 1978, Gussenhoven 1984, t3aart t987), and implemented in my program P R o s a . This program ha...

We present a finite state technology based system capable of performing metrical scansion of verse written in English. Scansion is the traditional task of analyzing the lines of a poem, marking the stressed and non-stressed elements, and dividing the line into metrical feet. The system’s workflow is composed of several subtasks designed around finite state machines that analyze verse by perform...

This paper presents the prosodic component of a French text-to-speech synthesis system based on a metrical model of rhythm and intonation in which the prosodic well-formedness of utterances is governed by a set of rhythmic and morphosyntactic constraints. We first set out the theoretic basis of the generation of prosodic levels that correspond to the metrical and tonal structure of utterances. ...
