The observed detection peak frequencies of the I-shaped and bowtie-shaped antennas possessing very long dipole arms indicate that the lowest limit of the frequency detected in a typical THz-TDS using a GaAs photoconductive antenna as emitter/detector is around 0.2 THz.
Fig. 1 Training goal and observed detection rate of each stage.
However, the detection rate is decreased as the stage proceeds in the cascade, and there is a large gap between the observed detection rate and the theoretical one.
The observed detection distances may be shorter than on a level roadway, but the results about the effects of lighting conditions are consistent.
As observed, detection efficiencies of the three algorithms decreased as the data size increased, while the detection efficiency of the proposed algorithm is lower than those of the other two algorithms.
The authors prepared serial dilutions of S. Typhi in blood and observed detection limits of 250 CFU/ml for their real-time assay and 25 CFU/ml for detection by blood culture.
