Basic theory and algorithm for Inter-Belt analysis;

A new theory and the corresponding inter-belt model for phonon dispersion analysis of carbon nanotubes are developed for phonon dispersion analysis of carbon nanotubes based on the symplectic theory and algorithm established in applied mechanics in recent years.

An application-layer multicast routing algorithm based on bounds of interface bandwidth and delay constrain;

Input signals are divided into several subbands using filters with critical band,and then in each subband,adaptive processing is made respectively in the time domain according to the short-term SNR.

Based on spectral subtraction method,this paper uses the masking properties in critical bands of human ears to attenuate the musical noise introduced by spectral subtraction.

By studying the principle of hearing system in identification of sound signal,a method of feature extraction for passive sonar target based on critical band spectrum energy is proposed.
