Progress of microwave and millimeter-wave technologies has made possible advanced diagnostics for application to various fields, such as, plasma diagnostics, radio astronomy, alien substance detection, airborne and spaceborne imaging radars called as synthetic aperture radars, living body measurements, and automobile radars for collision avoidance and adaptive cruise control. Transmission, reflection, scattering, and radiation processes of electromagnetic waves are utilized as diagnostic tools which are classified to active and passive diagnostic systems. In the active system, microwave/millimeter-wave reflectometry (radar) is thought to be essential and most prospective, since it has higher perception accuracy and robustness under the conditions of rain, fog, and snow than conventional technique using laser radar devices. In this report we focus on the technology advances in microwave/millimeter-wave region and the application results of diagnostic systems, specifically by use of imaging technique and ultra-wide band radar technique.","PeriodicalId":259577,"journal":{"name":"2008 11th IEEE International Conference on Communication Technology","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126284915","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}

Most previous works focusing on composite service execution are based on the centralized architecture while the decentralized architecture can avoid the large amount of round-trip messages thus significantly reduces the transmitting costs in the network. However, to implement the decentralized service execution architecture, the existing Web service choreography languages are not adaptable. In this paper, we first present the decentralized execution architecture for composite service with the analysis of its advantages. Then, we propose an extension for the service choreography language to support the decentralized service execution architecture. The prototype system is presented to show the practicability of our approach.","PeriodicalId":259577,"journal":{"name":"2008 11th IEEE International Conference on Communication Technology","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125714921","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}

Solid-state spatial power combiner is issued to replace traveling wave tube amplifier (TWTA) in space communication systems. To comply with space requirements a new compact Ka-band spatial power combining architecture is proposed using a double-faced tray. To match the 2 times 2 combining structure, double antipodal finline is designed to achieve power distributing/combining and transition between waveguide and microstrip. A 29~30 GHz spatial power combiner is designed following this architecture.

If this phonetic information in his/her speech data can be suppressed, a robust TI speaker identification system will be realized by using speech features having less phonetic information. In this paper, we propose a TI speaker identification method that suppresses the phonetic information by a subspace method, under the assumption that a subspace with large variance in the speech feature space is a ldquophoneme-dependent subspacerdquo and a complementary subspace of it is a ldquophoneme-independent subspacerdquo. Principal Component Analysis (PCA) is utilized to construct these subspaces. We carried out GMM-based speaker identification experiments using both a new feature vector of the proposed method and the conventional MFCC. As a result, the proposed method reduced the identification error rate by 21% compared with the conventional MFCC.","PeriodicalId":259577,"journal":{"name":"2008 11th IEEE International Conference on Communication Technology","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133882581","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}
