Examples in Context
- Objective To evaluate the influence of power, irradiation time, pulse energy and frequency of pulsed Ho ∶ YAG laser on its biological effects.
- By mapping a one dimensional function of time ( or frequency ), the time frequency representation can localize the signal energy in both the time and frequency directions.
- Through extracting time domain features, energy, entropy, energy entropy, sequential characteristic and correlation dimension of different frequency bands by wavelet decomposition and empirical mode decomposition, it constituted eleven feature libraries, and provide a data base for applied research of kernel function.
- Hilbert energy spectrum can clearly express the energy distribution with time and frequency in detail, and most energy are concentrated in a definitive range of time and frequency, but that of wavelet spectrum lines are distributed in a wider frequency range.
- The method of time frequency domain spherical divergency and absorption compensation can be used to compensate the excitation energy in time and frequency domain, so we can reach the aims of amplitude preservation and enhancing seismic resolution.
