The effect of masking due to fluctuating sources on speech intelligibility is a phenomenon difficult to predict. Intelligibility scores vary with the efficiency of the energetic masking while the linguistic content of the message and listener’s cognitive performances add to the general incertitude that peaks for the case of masking speech. The present contribution proposes a signal-based assess...

This paper introduces an approach that allows swarm robots to maintain their individual and collective energetic homeostasis. The on-board recharging electronics and intelligent docking stations enable the robots to perform autonomous recharging from low energy states. The procedure of collective decisionmaking increases collective efficiency by preventing bottlenecks at docking stations and th...

As device dimensions are scaled down, single event transients (SET) are increasingly affecting the reliability of integrated circuits. An SET is a transient voltage perturbation caused by an energetic particle strike at the semiconductor. This work studies the applicability of bulk built in current sensors (bulk-BICS) for SET detection in deep-submicron technologies. The bulk-BICS detects the t...

The aim of this research was to develop a path-flow analysis model from age-group swimmer’s performance based on biomechanical and energetic parameters. Twenty two young male age-group swimmers with several competitive levels volunteered to serve as subjects. It was assessed swim velocity, stroke length, stroke frequency, stroke index, propulsive efficiency, critical velocity and 200 m freestyl...

OBJECTIVE The purpose of this study was to evaluate the hemodynamic changes in left ventricular function before and after patent ductus arteriosus ligation in premature infants with regard to the energetic efficiency of left ventricular pumping. METHODS Thirty-five premature infants who underwent patent ductus arteriosus ligation were enrolled in this study. Left ventricular efficiency was ev...
