In order to detect the indoor wandering of demented elders living alone in real time, this paper proposes a light-weight wandering detection system named LWDS. Specifically, the LWDS system first collects the location information with timestamp using a pair of pyroelectric infrared sensors mounted on the doors of each room, and then classifies the ongoing trajectory consisting of a series of locations into different wandering locomotion patterns according to an established wandering model. After a trajectory has been detected as containing wandering behavior, the developed system will send an alert to their carers for necessary treatment. The non-intrusive and easy-to-deploy properties ensure the proposed LWDS system can find wandering behaviors in a cost-effective and energy-efficient manner around the clock. An experimental evaluation conducted on a group of real data collected from two elders showed that the LWDS is effective in detecting indoor wandering when they moved across different rooms and obtained a detection ratio of more than 90.03% for the wandering patterns.","PeriodicalId":343641,"journal":{"name":"2014 International Conference on Orange Technologies","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129144576","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}

Image/video SR is currently a very active area of research because it is used in various applications. The basic idea of the proposed scheme is based on the concepts of pattern redundancy and parallel computing. Global and local motions of pixels are well estimated by exploiting the repeated and structured patterns existing in the most nature images. The value of a missing pixel in the desired high resolution image is obtained by calculating the weighted average of the selected pixels according to the estimated motions, which is able to preserve the intrinsic geometric structure of the original low resolution image/video stream. After that, the estimated pixels' values will be re-corrected by using iterative back projection (IBP) approach in which auxiliary high frequency information embedded. The proposed scheme is mainly implemented in parallel programming strategy based on Compute Unified Device Architecture (CUDA), to reconstruct desired high resolution image/video steam from its low resolution counterparts. Experimental results show that the proposed method has high performance on both the visual quality and real time processing speed.","PeriodicalId":343641,"journal":{"name":"2014 International Conference on Orange Technologies","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131293959","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}

In line with Telehelath, Home Area Network (HAN) has also seen broad deployments and has expanded conventional households to support latest electronic devices that are equipped with network connectivity. Telehealth applications are starting to be designed to take advantages of the HAN environment and are providing healthcare at the patients home, i.e., facilitates hospital at home via video-consultation-call (VCC). However, some of these Telehealth applications are highly delay sensitive and require higher bandwidth priority and a network load-balancing system in order to produce best quality of service (QoS). We observed that typical HAN is established without bandwidth priority and network-load-balancing systems. This lack of management causes HAN to produce unacceptable QoS for Telehealth applications. In this scenario, we propose a scheme to enhance HAN while providing better quality of VCC to support Telehealth services. Our scheme controls the Internet traffic within the HAN network infrastructure environment. In our experimental setting, we implemented a real network test-bed based on HAN where two-way Skype VCC was established and the quality of packet-loss was measured. Skype was chosen for its wide availability and support on all types of computing devices (PC, mobile, laptop etc.). Our results indicate that packet-loss fluctuates between ~5-16% when user datagram protocol (UDP) traffic is utilised concurrently by other devices in HAN. It also demonstrated that our scheme could enhance HAN performance for VCC as it reduced packet-loss down to ~0.3 %.","PeriodicalId":343641,"journal":{"name":"2014 International Conference on Orange Technologies","volume":"160 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120936552","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}

In clinical applications, thirty-four aneurysm patients have through the dynamic volume scan with wide detection platform by TOSHIBA 320 Slice CT and obtained fine single-pass imaging results all of which had no phase artifacts. The quality of scanning images were evaluated and compared with computed tomography angiography (CTA) and convention cerebral vascular DSA angiography.
