2-[6-Thioxo-5-(2,4,6-trimethylÂphenÂyl)-1,3,5-thiaÂdiazinan-3-yl]acetic acid
In the molÂecule of the title compound, C14H18N2O2S2, the 1,3,5-thiaÂdiazinane-2-thione ring adopts an envelope conformation with one of the N atoms at the flap position. The plane throught the five co-planar atoms of the heterocycle is oriented at a dihedral angle of 80.59 (8)° with respect to the aromatic ring. In the crystal structure, weak interÂmolecular O—H⋯S interÂactions link the molÂecules into chains along the b axis
Driver’s Face Pose Estimation Using Fine-Grained Wi-Fi Signals for Next-Generation Internet of Vehicles
Driver’s behavior and gesture recognition are most significant in the emerging next-generation vehicular technology. Driver’s face
may provide important cues about his/her attention and fatigue behavior. Therefore, driver’s face pose is one of the key indicators
to be considered for automatic driver monitoring system in next-generation Internet of Vehicles (IoV) technology. Driver
behavior monitoring is most significant in order to reduce road accidents. This paper aims to address the problem of driver’s
attentiveness monitoring using face pose estimation in a nonintrusive manner. The proposed system is based on wireless
sensing, leveraging channel state information (CSI) of WiFi signals. In this paper, we present a novel classification algorithm
that is based on the combination of support vector machine (SVM) and K nearest neighbor (KNN) to enhance the
classification accuracy. Experimental results demonstrate that the proposed device-free wireless implementation can localize a
driver’s face very accurately with an average recognition rate of 91:8%
