This paper presents a drowsiness detection model that is capable of sensing the entire range of stages of drowsiness, from weak to strong. The key assumption underlying our approach is that the sitting posture-related index can indicate weak drowsine

This study proposed a robust estimation of thermal sensation for vehicle occupants using seat-belt-type sensors and thermal cameras. The estimation of thermal sensation of a vehicle faces challenges, including the difficulty in measuring the clothing

We studied the optical creation and modulation of magnetic flux quanta in a YBa/sub 2/Cu/sub 3/O/sub 7-/spl delta// thin film loop by observing terahertz emission excited with femtosecond laser pulses. The magnetic flux is created and modulated in th

YBCO films are exposed to Ar ion beams in order to obtain flat surfaces and they are characterized by the time-resolved reflection pump-probe method excited with femtosecond optical pulses. The amplitudes of the reflectivity change of the ion-beam pr

We characterize the YBa2Cu3O7-δ (YBCO) thin film surfaces flattened by ion beam exposure by means of atomic force microscopy (AFM), a femtosecond time-resolved pump-probe method, optical spectra, and Raman spectra. It is revealed that lower energy i
