Automatically predicting child engagement in dyadic interactions
… social development and a lack of engagement can signal delays, such as ASDs. We demonstrate the first methods capable of predicting the engagement of a child automatically. We apply computer vision techniques to predict child engagement during unscripted two-person interactions. We show that …

Atmospheric signal delay affecting GPS measurements made by space vehicles during launch, orbit and reentry
… present neutral atmosphere, ionosphere and total delays experienced by GPS signals traveling to space vehicles during launch, orbit and reentry. I calculate these delays for receivers at 0 km to 1700 km altitude by ray-tracing through the Global Reference Atmosphere Model (1999) and the …

Robust decentralized control of power systems through excitation systems and thyristor controlled series capacitors
… the second part, indices for control signal selection and mode effectiveness and interaction are developed. They are applied in Thyristor Controlled Series Capacitor damping control, which is to improve inter-area oscillation damping over a range of operating conditions, for evaluating …

Resolution of signal components of a resultant electromagnetic wave received in a multipath field of microwave frequencies
… propagation on radio links is associated with signal delays and signal level fades on which adversely influences the system performance.<br/><br/>For efficient frequency planning the knowledge of the multipath geometries involved is required. This knowledge can be obtained by resolving the …

Measurements and modelling of reflection and transmission from smooth and rough surfaces at 62 GHz
… propagation mode. This latter is associated with signal delays and signal level fades due to reflections, scatters, transmissions and diffractions by obstacles surrounding the environment. Indoor and outdoor building layout often influence the signal. In order to understand and mitigate the signal …

Efficient light emission from bismuth-doped rare earths compounds for Si microphotonics
… are required, thus leading to an increase of signal delays and to electromagnetic interferences that cause power dissipation and limit the total performances of a chip. A possible solution to this problem can be obtained by replacing the electrical interconnections with the optical ones by the …

Spatial Audio for Bat Biosonar
… echoes typically includes analysis of acoustic signals from microphones and/or microphone arrays, using time difference of arrival (TDOA) between array elements or the microphones to locate flying bats (azimuth and elevation). This has provided insight into transmission adaptations with respect …
