Currently used reliability calculation model is not very suitable for networking environment with many-to-many type of communication. In this paper we propose a novel method to quantify service availability in datacommunication networks. The proposed method reflects the multipoint-to-multipoint nature of datacommunication. The main idea of the proposed method is utilization of a special class of mathematical operations called t-norms.","PeriodicalId":341695,"journal":{"name":"2011 34th International Conference on Telecommunications and Signal Processing (TSP)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121354418","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}

By optimizing the architecture of the encoder, three kinds of dependences are eliminated or weakened, including the context dependence, the memory accessing dependence, and the control dependence. We divide the execution of CAVLC into three stages: two scans, component-oriented coding, and lag packing. For each stage, data of a frame can be processed synchronously. Experimental results show that the proposed parallel CAVLC encoder can achieve more than 30 times speedup when compared with the CPU version, and a real-time process for 720p @ 30p can be achieved. The throughput of the presented CAVLC encoder is 11.17 to 6.29 times higher than that of the published software encoders on DSP and multi-core platforms.","PeriodicalId":341695,"journal":{"name":"2011 34th International Conference on Telecommunications and Signal Processing (TSP)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129221338","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}

As application example using the presented new active building block a novel voltage-mode first-order all-pass filter is proposed, where instead of floating resistor the electronically controllable intrinsic resistance of the Y terminal is used. Hence, the circuit is resistorless and it shows low sensitivity performance. The behavior of the all-pass filter is verified by SPICE simulations and the TSMC 0.35 μm level 3 CMOS process parameters are used to confirm the theoretical analysis.","PeriodicalId":341695,"journal":{"name":"2011 34th International Conference on Telecommunications and Signal Processing (TSP)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128612457","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}

LDA is a popular feature extraction technique for face recognition. Likewise, the CCA as a novel method is applied to image processing and biometrics too. CCA is a powerful multivariate analysis method and for that case it was applied on faces recognition. In the paper, a proposed methodology for face recognition based on information theory approach of coding and decoding the face image is presented. Developed algorithm has been tested on 20 subjects from FERET database. Test results gave a recognition rate for LDA method quite the good recognition rate 100% respectively 83% for a small number of input subjects 5 respectively 10. For a large number of inputs images is recognition rate very poor about 40% For our proposed CCA method is average recognition rate about 99% for FERET face database.","PeriodicalId":341695,"journal":{"name":"2011 34th International Conference on Telecommunications and Signal Processing (TSP)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115633470","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}

Unfortunately, the world is rapidly aging, and aging degrades vision performance. In order to create future home/campus environments, we clarify the basic attributes of visibility that are needed to support low vision, or vision-impaired people. In an experiment, 30 subjects wear goggles simulating visual disturbances (constriction of the visual field and wall-eye) to determine the maximum distance that permitted successful recognition between the subject and a sign. The signs used here have 5 different patterns, from a simple humanoid to a humanoid plus blinking bricks. Subjects' comments on visibility are also gathered after the distance experiment. The result implies the size of sign needed for vision impaired people in home/campus environments.","PeriodicalId":341695,"journal":{"name":"2011 34th International Conference on Telecommunications and Signal Processing (TSP)","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127146226","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 segmentation method combines spatial continuity of individual slices and a genetic algorithm. Using the genetic algorithm a threshold is set for the selection of video segments. The MRI technique is one of the non-invasive imaging methods especially for the soft tissues of the human body, which include the temporomandibular disc. After segmentation, a 3D (three-dimensional) model was realized using the marching cube method, and was subsequently smoothed using the Laplace smoothing algorithm.","PeriodicalId":341695,"journal":{"name":"2011 34th International Conference on Telecommunications and Signal Processing (TSP)","volume":"C-28 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121001494","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}
