This paper studies the input design problem for system identification where time domain constraints have to be considered. A finite Markov chain is used to model the input of the system. This allows to directly include input amplitude constraints in the input model by properly choosing the state space of the Markov chain, which is defined so that the Markov chain generates a multi-level sequence....
It is of particular importance to detect and quantify obstructive pathological conditions in mechanically ventilated patients, especially in the presence of expiratory flow limitation (EFL), in order to help the clinicians in the choice of the most appropriate ventilation and pharmacological strategies. Aim of this work is to test by simulation a non invasive procedure for estimating the total apparent...
Expiratory flow limitation (EFL) is frequent in mechanically ventilated patients with obstructive pulmonary disease and its prompt detection is important to optimize respiratory assistance. The present study aims to compare by simulation two methods for the detection of flow limitation in intensive care unit: the negative expiratory pressure (NEP) method and the external resistance (/spl Delta/R)...
A mathematical model of solute kinetics oriented to the simulation of hemodialysis is presented. It includes a three-compartment model of body fluids (plasma, interstitial and intracellular), a two-compartment description of the main solutes K+,Na+,Cl- urea, HCO 3- ,H+), and acid-base equilibrium through two buffer systems (bicarbonate and noncarbonic buffers). Tentative values for the main model...
