Validation of Tissue Modelization and Classification Techniques in T1-Weighted MR Brain Images

Jean-Philippe Thiran, Meritxell Bach Cuadra, Torsten Butz, Bram Platel

We propose a deep study on tissue modelization and classification Techniques on T1-weighted MR images. Three approaches have been taken into account to perform this validation study. Two of them are based on Finite Gaussian Mixture (FGM) model. The first o ...

Markovian Term Structure Models in Discrete Time

Damir Filipovic

In this article we discuss Markovian term structure models in discrete time and with continuous state space. More precisely we are concerned with the structural properties of such models if one has the Markov property for a part of the forward curve. We in ...

Markov chain modeling of chaotic wandering in simple coupled chaotic circuits

Martin Hasler

In this study, chaotic wandering phenomenon observed in simple coupled chaotic circuits is modeled by Markov chains. As coupling parameter increases, the solution of the coupled chaotic circuits starts to wander chaotically over 6 different phase states wh ...

HMM2- A Novel Approach to HMM Emission Probability Estimation

Hervé Bourlard, Samy Bengio, Katrin Weber

In this paper, we discuss and investigate a new method to estimate local emission probabilities in the framework of hidden Markov models (HMM). Each feature vector is considered to be a sequence and is supposed to be modeled by yet another HMM. Therefore, ...

Speachreading using shape and intensity information

We describe a speechreading system that uses both, shape information from the lip contours and intensity information from the mouth area. Shape information is obtained by tracking and parameterising the inner and outer lip boundary in an image sequence. In ...

Stochastic model of inhabitant behavior in regard to ventilation

Jean-Louis Scartezzini, Claude-Alain Roulet

Airflow rates, hence energy consumption, are directly affected by the amount of open area and consequently by the inhabitant behavior with respect to window opening. This report describes stochastic models using Markov chains, and used to generate time ser ...

Compression of multi-year meteorological data

Jean-Louis Scartezzini

Dynamic simulation programes require hourly values of solar radiation and ambient temperature forming large files, which are usually difficult to handle with available personal computers (PC). This report describes stochastic models of these variables whic ...

Possibilities and limitations of Markovian stochastic models of passive solar buildings

Thomas Liebling

Dynamic simulation is an accurate but time-consuming way tu calculate energy and thermal comfort performances of passive solar buildings. Simplified methods, originally developed to evercome their disadvantage, unfortunately do not provide the same quantit ...

Electric circuit analysis

The contribution of Lausanne Polytechnic to the development of modern methods of analysis of power networks, in particular to the activities of a group of engineers constituting the `Electric Network Studies Centre', is described ...
