Dans cet article, nous proposons d’étudier un estimateur du paramètre de Hurst pour des trajectoires browniennes fractionnaires échantillonnées irrégulièrement. Les trajectoires sont simulées à partir de l’algorithme de Cholesky et l’estimation du paramètre de Hurst est obtenue par maximum de vraisemblance, ces deux techniques étant coûteuses en temps de calcul mais bien adaptées pour ce type de données. Nous présentons des tableaux contenant l’estimation de l’indice d’autosimilarité en fonction...
Among several alternative viewpoints for building software quality metrics, evaluating the consistency between different models in a software specification or implementation appears to be fruitful. An obvious difficulty is that different models are usually expressed by means of different concepts, and then, confronting heterogeneous representations is not straightforward. In this paper, we propose a solution for measuring the consistency between the architecture and the communication models. After...
