Firstly, by solving Navier-Stokes equations, the velocity distributions in the vessels with various expansion degrees are calculated. Secondly, power spectral density (PSD) of the Doppler signals is estimated according to the relationship of velocity profiles and power spectral density. Finally, Doppler signals are generated using cosine-superposed methods. The results show that the spectra of Doppler signals are similar to those found in practice. Therefore, the proposed approach is useful for simulating the spectra of Doppler ultrasound signals.","PeriodicalId":393802,"journal":{"name":"2010 International Forum on Information Technology and Applications","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125281223","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 paper discusses the interpreting mechanism of natural spatial query language with spatial knowledge bases which include spatial dictionary, spatial query sentence pattern, grammar rule, spatial semantics, etc. The natural language in the paper especially refers to Chinese. Through the interpreting mechanism, a Chinese spatial query sentence will be transferred to one or several spatial operations and spatial information which queried by users will be supplied. The important components of the interpreting mechanism include spatial segmenting, parsing, semantics analysis, executing of spatial query functions, organizing and expressing of query results, ect.

By adopting Partially Blind Signature algorithm in the generation of AIK triples, PBS-based one provides absolute untraceability to user’s transactions because the public AIK is blinded while being signed by the PrivacyCA.

The method first extracted training templates using interactive video cutout technique, and automatically segmented the video into 3D spatial-temporal volumes using improved Mean Shift algorithm. Then we slide the template across the video and compute the matching distance. We complement our shape-based features with flow, and efficiently match the volumetric representation of an action against over-segmented spatial-temporal video volumes. Thresholding the correlation distance and finding the peaks give us locations of potential matches. The experiment results indicate that this method achieves human’s action detection robustly in crowded, dynamic environment.","PeriodicalId":393802,"journal":{"name":"2010 International Forum on Information Technology and Applications","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131794375","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}
