... variations of the frequencies because we want to track killer whale vocalizations. Moreover, tracking the frequency variations for extracting the killer whale vocalizations is possible because these ... is important to know the frequencies of the chirps rather than the value of the sampling frequency. The spectrogram is provided in Figure 2(B). The first step...

... the simple predicted sequence of the end effectors. The bits of the end effectors and the other general joints are sent to the decoder, respectively. For the bits of the general other joints, the ... de- quantization of the bits, we retrieve the position of the end ef- fector of each frame. Finally, the angle conversion of the end effectors is added to c...
