Sub-band average-energy and the variance of the wavelet coefficients are the common algorithms, the disadvantage of the former algorithm is the limitation of only suitable for Gaussian white noise environment, while the latter algorithm can't overcome the drawback in Time-consuming, bad real-time. According to these problems, this paper puts forward optimization algorithm combined with the two methods. It improves applicability in speech endpoint confirmation. The MATLAB simulation results show that the system using the optimization algorithm achieved optimal accuracy and quickness, and gained anticipative effect.","PeriodicalId":20466,"journal":{"name":"Proceedings of 2011 6th International Forum on Strategic Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88936506","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is shown that the SAXS profile is hardly constant with Porod's law showing a negative and positive slope, suggesting that an interfacial layer exists between the nanoparticles and PI matrix in films when content of more than 5%. This suggests that the inorganic nanoparticles linked to the PI matrix through covalent bond. However, the only positive deviation exists in the film of content 5%. The reason is that there is a fluctuation of electron density in hybrid system. This kind of material has also been proved to possess both surface and mass fractal structures.","PeriodicalId":20466,"journal":{"name":"Proceedings of 2011 6th International Forum on Strategic Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86049953","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The one dimensional and self-consistent fluid model of gas discharge was established which is composed by the electron and ion continuity and momentum transfer equations, and the nonlinear equations were solved by using the SG algorithm. The results showed that the short gap discharge of electrode coverage behaves the typical nonlinear characteristic such as Hopf bifurcation and Chaos. Two ways leading to Chaos have been found by changing discharge conditions, one is quasi-period and the other is double-period. Seemingly random discharge may reveal the hidden simple laws, through studying nonlinear phenomena of the short gap discharge of electrode coverage, especially the phenomena of Chaos to find out the common law, which is generally followed by complex issues.","PeriodicalId":20466,"journal":{"name":"Proceedings of 2011 6th International Forum on Strategic Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81005273","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
