They are characterized by special stress upon the falling tone used at the beginning of a sentence to initiate a tone,or contrastively used with the level tone so as to achieve the effect of a flowing rhythm.

There are mainly two types of markers: the initial voiced consonant and the falling tone.

This paper has made a research on rhythms between the falling tone and the entering tone in the rhythm prose from the Qin Dynasty to the Southern and Northern Dynasties,and then made use of the theory of the falling tone coming from-s ending to analyze the reasons for rhythm between the falling tone and the entering tone and the phonetic system and era when-s ending wholly lost.

The paper describes the study of combination of denoising and edge detection based on wavelet transform with design of treatment planning in radiotherapy.

Taking the advantage that the local linear projective algorithm (LLPA) does not have to know the dynamics of chaotic signals in advance, it uses this algorithm in the receiver end of Chaotic Shift Keying (CSK) system for the noise reduction.

Wavelet Analysis and Its Application in Denoising the Spectrum of Hyperspectral Image

A denoising and baseline correction method based on wavelet transform and their parameters choosing method were developed to remove noise and correct baseline in the spectrum effectively.
