Abstract: A first apparatus obtains first information, where the first information includes information about a road and/or information about an object on the road, and the object on the road includes a vehicle and/or a pedestrian on the road. The first apparatus determines a driving behavior of the first apparatus based on the first information and a capability of the first apparatus. Even if the capability of the first apparatus cannot be used to process complete information of the first information, the first apparatus can still determine the driving behavior of the first apparatus based on a part of information in the first information. This resolves a problem that a capability of an apparatus cannot fully match road side information. According to the technical solution, apparatuses with different capabilities can cooperate with different roads with different capabilities, to improve travel efficiency and safety.

Abstract: A method for qualitative identification and quantitative determination of caffeine in a drug. In the method, terahertz absorption coefficient spectra of drugs with different concentrations of caffeine are measured, from which the frequency points, amplitudes and peak areas of characteristic peaks of the drugs with different concentrations of caffeine are obtained as characteristic quantities. Concentration gradients are established between the concentrations and the characteristic quantities, respectively. The characteristic quantities are imported to the SVR model to establish a training set and a test set. Finally, the qualitative identification and quantitative analysis of caffeine in unknown drugs are achieved.
