In the context of detecting ‘paralinguistic events’ with the aim to make classification of the speaker’s emotional state possible, a detector was developed for one of the most obvious ‘paralinguistic events’, namely laughter. Gaussian Mixture Models were trained with Perceptual Linear Prediction features, pitch&energy, pitch&voicing and modulation spectrum features to model laughter and speech....

The purpose of this study was to identify different types of occupational well-being based on the circumplex model (Russell, 1980; Warr, 1994), and to examine how these types are related to the Big Five personality profiles. The middle-aged participants were drawn from the Jyväskylä Longitudinal Study of Personality and Social Development (N = 183). Application of a person-oriented approach wit...

This paper deals with matrix representations of linear orders, mixtures of order matrices and the non-integral solutions of the linear systems defining them.

This paper describes a simulation model of nanoparticle assemblies formed by spray deposition. The simulation deposits nanoparticles via a semi-mechanistic process, which in spite of its simplicity generates morphologies of considerable complexity. The experiments reveal several relationships between nanoparticle parameters such as their relative proportions in mixtures, and resulting surface p...

Emotional content is a major component in music. It has long been a research topic of interest to discover the acoustic patterns in the music that carry that emotional information, and enable performers to communicate emotional messages to listeners. Previous works looked in the audio signal for local cues, most of which assume monophonic music, and their statistics over time. Here, we used gen...

In this paper we discuss a Bayesian approach for nding latent classes in the data. In our approach we use nite mixture models to describe the underlying structure in the data, and demonstrate that the possibility to use full joint probability models raises interesting new prospects for exploratory data analysis. The concepts and methods discussed are illustrated with a case study using a data s...
