Since the stenosis transformation is gradual, the patients usually can't be aware of abnormality immediately. Therefore a convenient non-invasive examination method is needed to help the general public monitor the status of carotid artery stenosis. In this work we used electronic stethoscope to record the sound of blood flow, and extract the systolic fragments. The experimental results reveal the approximate entropy can be used as a preliminary feature to detect carotid stenosis (p <;0.01).","PeriodicalId":340402,"journal":{"name":"2015 IEEE International Conference on Consumer Electronics - Taiwan","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125925808","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 WRAN system uses the white spaces of the 50-860 MHz TV spectrum for increasing the spectrum efficiency. To cover such wideband operating range, we proposed a novel LO technique. This technique not only increases the operating range but also decreases the phase noise of the LO. Experimental results show that the proposed LO can achieves a wide operating range from 50 MHz to 1 GHz. The phase noise of the LO at 1 MHz offset frequency is as low as -131 and -132 dBc/Hz at 50 MHz and 1 GHz, respectively.","PeriodicalId":340402,"journal":{"name":"2015 IEEE International Conference on Consumer Electronics - Taiwan","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126953834","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}

But maximizing the parallelism of a pipeline and deepening pipeline cause more penalties so that branch predictor is more and more important. One of the efficient ways to improve its performance is generally to increase the size of the branch predictor. However, increasing the size of branch predictor necessarily involves the increase of memory indexing time and power consumption. Therefore, to improve the performance of branch predictor considering the mobile environment, we have studied the effect on performance improvement by changing the other factors while remaining the size of the memory fixed with 2-level branch predictor. We experimented to investigate the performance improvement by modifying the associativity of Branch Target Buffer (BTB) and the size of Branch History Register (BHR). The simulation was performed using SimpleScalar 3.0 based on ARM Cortex-A15 and benchmarks from SPEC CPU2000. As a result, in the 2-level branch predictor structure, when reducing the length of BHR in 8 bit, the increase of Instruction Per Cycle (IPC) is the highest as 0.599%. Therefore, we concluded that to modify the length of BHR of branch predictor is most effective way to improve the performance of the processor.","PeriodicalId":340402,"journal":{"name":"2015 IEEE International Conference on Consumer Electronics - Taiwan","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129879515","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}

While the smartphone receives the data from sensing module, the designed Android user interface APP will mark the position with abnormal road condition on Google Maps using the GPS of smartphone.
