Modeling and computer simulation of physiological rhythms and behaviors at home for data fusion programs in a telecare system

This is the authors' abstract. We don't add key points for this paper.

The multivariate simulation is based on models of physiological and physical activities using Markov chains and Petri networks and is designed to produce the medical and behavioral data normally obtained from a patient living in the HIS/sup 2/. The HIS/sup 2/ is an experimental platform to develop and evaluate technologies that ensure high levels of safety and health care for residential treatment. It records a patient's vital signs, daily activities, and metrological conditions that are then interpreted and manipulated in the data fusion programs. The main goal of the computer simulation is to generate databases that allow us to assess the alarm triggering procedures and tools used in the data fusion analysis programs developed for the HIS/sup 2/. An example of data fusion program, the system for the automatic measurements of the circadian rhythms of activity, which uses these databases, is briefly presented.
