In mobility service environments, recognizing the user condition and driving status is critical in safety experiences. While speech emotion recognition one of possible features to predict driver status, current models have a fundamental limitation: they target classify only single classes, not multi-classes. It prevents comprehensive understanding driver’s intention during driving. addition, devices inherently generate noises that might affect performances service. Considering we investigate...

Nanocrystals (NCs) of CsPbX3 , X = Cl, Br, or I, have excellent photoluminescent properties: high quantum yield, tunable emission wavelengths (410-700 nm), and narrow band widths. CsPbBr3 NCs show promise as a green-emitting material for use in wide color gamut displays. have, however, not been commercialized because they are sensitive to moisture heat. To avoid these problems, this work attempts introduce into five zeolites. The zeolite product, Pb,Br,H,Cs,Na-X, shows superior stability...
