In the proposed array 64.3% impedance bandwidth is achieved along with the good radiation characteristic throughout the band of interest.

RDF is the de-facto standard for data representation on the Semantic Web. The universal adoption of this standard can be attributed to the fact that it has a flexible model. Due to the widespread adoption of Semantic web, a sudden steep increase in the amount of RDF data has been witnessed. This massive volume of RDF data can't be handled by the traditional Centralized RDF management systems. Thus comes into the picture the need for Distributed RDF data management systems which can distribute this RDF data on a cluster of nodes. So, the bottlenecks of the Centralized RDF systems regarding volume and efficient querying can be overcome. This paper presents a detailed description and comparison of the different Centralized and Distributed RDF data management systems.","PeriodicalId":340007,"journal":{"name":"2016 International Conference on Emerging Trends in Communication Technologies (ETCT)","volume":"266 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123107366","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 major problem in life sign detection is the reflection due to wall which amounts for substantial loss of energy. The remaining energy signal pass through wall and propagated towards human being as target. Finally the weak reflected signal from target reach to the receiving antenna after passing through wall again. To improve the signal strength of the target and hence detection, clutter reduction technique is proposed. It is observed that after application of clutter reduction technique, the microwave radar system can detect human life sign. The performance of Singular Value Decomposition (SVD) based clutter reduction technique is compared with moving average clutter reduction technique. It is observed that SVD technique outperforms moving average technique in removing clutter.","PeriodicalId":340007,"journal":{"name":"2016 International Conference on Emerging Trends in Communication Technologies (ETCT)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125669220","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}

These configurations are also termed as planar and staggered-OTFT configurations, respectively. On the basis of result analysis, it is found that BGBC configuration have lower drive current in comparison to bottom gate top contact configuration because of larger barrier heights. Subsequently, it is also analyze that BGBC configuration has more impact on their performance parameters in comparison to BGTC configuration with variation in electrode thickness.
