This work analyzes regions of interest (ROI) on cardiac maps obtained from the regularity analysis of VF records, providing information about signal regularity at each time instant and its spatial distribution. Cardiac registers were obtained using a 240-electrodes matrix located on left ventricle of isolated rabbit heart.

The technique will be very useful for the implementation of higher order numerical and asymptotical methods in computational electromagnetics. In this paper we show the 2D case (for curves). We will present a generalization for surfaces in the oral session during the symposium.

This work investigates the influence of sleep arousal on heart rate changes. 586 arousals from seven polysomnographic recordings were analysed, and the mean frequency of the RR series was obtained every 5 " from 20" before to 20" after the arousal. Results show that

Multiple feeding has been employed in order to generate dual polarisation. The theory of characteristic modes is used to explain the behaviour of the antenna.

The paper presents simulations of absolute and differential reconstructions of bodies within the Born approximation and of stronger diffracting objects. In addition a preliminary experiment is presented.
