چکیده

RÉSUMÉ – Modélisation probabiliste de l’interface « forme ~ fonction » pour des phénomènes intonatifs Nous explorons l’application des méthodes hybrides, reposant à la fois sur des représentations symboliques (phonologiques) et probabilistes dans la modélisation de l’interface « forme ~ fonction » pour des phénomènes intonatifs. À partir d’une représentation symbolique ancrée dans l’acoustique du signal et en accord avec les principes de la phonologie intonative, deux modèles d’enchaînement des catégories tonales sont dérivées moyennant les méthodes de grammaires probabilistes. Deux modèles probabilistes sont testés : le modèle des bigrammes et le modèle des patrons ; leur performance est ensuite évaluée à l’aide de la mesure d’entropie. Ces modèles sont enfin testés en prédiction. MOTS-CLÉS – Entropie, Grammaires probabilistes, Interface “Forme ~ Fonction”, Modèle des patrons, Prosodie

An Acoustic Study of Emotivity-Prosody Interface in Persian Speech Using the Tilt Model

This paper aims to explore some acoustic properties (i.e. duration and pitch amplitude of speech) associated with three different emotions: anger, sadness and joy against neutrality as a reference point, all being intentionally expressed by six Persian speakers. The primary purpose of this study is to find out if there is any correspondence between the given emotions and prosody patterning in P...

A New Stability Approach using Probabilistic Profile along Direction of Excavation

Estimation of the possible instability that may be encountered in the excavation slope(s) during the planning and application steps of the rock excavation processes is an important issue in geoengineering. In this paper, a modelling method is presented for assessing the probability of wedge failure involving new permanent or temporary slope(s) along the planned excavation dir...

Determination of a Matrix Function in the Form of f(A)=g(q(A)) Where g(x) Is a Transcendental Function and q(x) Is a Polynomial Function of Large Degree Using the Minimal Polynomial

Matrix functions are used in many areas of linear algebra and arise in numerical applications in science and engineering. In this paper, we introduce an effective approach for determining matrix function f(A)=g(q(A)) of a square matrix A, where q is a polynomial function from a degree of m and also function g can be a transcendental function. Computing a matrix function f(A) will be time- consu...
