Especially was discussed the method of artificial intelligence dedicated to the syntactic-based semantic inference of selected RTG visualizations with particular attention to the leg bones. The presented methodology makes possible to describe for each biological structure, its semantic characteristics, and allow to formulate a semantic meaning of pathological deformation. Presented approach proofed that cognitive informatics based on semantic formalisms can be used to develop a new classes of intelligent computer-aided diagnosis systems. Such systems authors called UBIAS (understanding based image analysis systems).","PeriodicalId":203066,"journal":{"name":"2008 International Conference on Multimedia and Ubiquitous Engineering (mue 2008)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123714520","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 central servers generate and distribute the keys in traditional wired networks, distributive key management systems are used in mobile ad hoc networks where central approaches will fail in such dynamic, high mobility networks. Threshold cryptography1 has been proposed to provide a reliable, distributive key management for networks. In an (n, t + 1) threshold system, there are n servers to provide key generation and distribution when needed for the whole network. From these n servers, any x servers (t < x les n) can co-operate and generate a key for any node. Until now, threshold cryptography has remained only a theory. No practical key management system has been proposed to use threshold cryptography that mentioned what kind of shares servers will have in common and the practical way of creating the key from these shares . In this paper, we will construct a practical (n, t + 1)-threshold key management system using maximum distance separable codes (MDS).","PeriodicalId":203066,"journal":{"name":"2008 International Conference on Multimedia and Ubiquitous Engineering (mue 2008)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126662206","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 many proposed algorithms assumed the shape of a polyp as a spherical cap, so the algorithms are not flexible when the polyps are irregular shapes. In this paper, we propose a mapping using regional unit sphere (MuRUS) method to overcome the problem caused by unexpected polyp shapes. The MuRUS has shape invariant and size invariant properties. Our method was applied to colon CT images from 3 7 patients each having a prone and supine scan. There are 45 colonscopically confirmed polyps. The results obtained by our algorithm were compared with those gold standards. 100% of polyps >= 10 mm in diameter were detected, 90% of polyps >= 6 mm in diameter were detected and 70% of polyps < 6 mm in diameter were detected at 7.0 FPs per patient.","PeriodicalId":203066,"journal":{"name":"2008 International Conference on Multimedia and Ubiquitous Engineering (mue 2008)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122177209","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 localization techniques nowadays apply ranging techniques to compute the location of the object wireless sensor network. Although the RSSI-based ranging technology is widely used and a cost-effective solution for localization in wireless sensor networks, a wireless ad hoc network is a fading signal environment that comprises noises. The noises cause RSSI to be unstable and lead to abrupt distance estimates. In this paper, we propose a verification-based localization method (VBLM) that determines whether a received signal is a noise. Our basic idea is that the unknown node uses another neighboring beacon to assist to verify the quality of received signal. The experimental results show that VBLM indeed reduces the localization error in the unstable radio sensor networks.","PeriodicalId":203066,"journal":{"name":"2008 International Conference on Multimedia and Ubiquitous Engineering (mue 2008)","volume":"206 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122613054","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}

Firstly, we divide a video into events based on target character's appearance and disappearance. Specifically, each event is an interval where the target character performs a certain action. And, it is characterized by a specific pattern of shots where the character appears and shots where he/she disappears. Then, we define a \"topic\" as an event where the target character performs an interesting action (e.g. fight, chase, kiss and so on). We extract such topics as events containing abnormal patterns, called \"bursts\". The experiments on different videos validate that character's appearance and disappearance are effective for obtaining semantically meaningful events. From these events, we could extract many interesting topics.","PeriodicalId":203066,"journal":{"name":"2008 International Conference on Multimedia and Ubiquitous Engineering (mue 2008)","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127962436","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}

Our proposed multimedia proxy system will cover the following concerns: (1) design a system architecture for the proposed multimedia proxy with MPEG-21 digital item adaptation, and (2) develop a cache and replacement policy for adapted MPEG-21 digital items. The proposed transcoding proxy adopts fine-grain cache and replacement algorithms for different multimedia objects and a cache scheme to smooth the delay variations of a cached object during subsequent playbacks.","PeriodicalId":203066,"journal":{"name":"2008 International Conference on Multimedia and Ubiquitous Engineering (mue 2008)","volume":"183 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124625800","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 order to address this problem, a relative stable P2P network architecture for live streaming media is presented. Our approach is that the architecture combines tree with clusters, and some super-peers are reserved in the clusters for peers' joining and departure, which is likely to be significant in a highly dynamic environment. In addition, the maximum accepted connection of each super- peer and its average disposing delay are adopted to select the optimal father peer. The experiment results show that the new architecture assures the improvement of real-time and live streaming media distribution in the large-scale P2P network, and at the same time, improves the scalability of the P2P network.","PeriodicalId":203066,"journal":{"name":"2008 International Conference on Multimedia and Ubiquitous Engineering (mue 2008)","volume":"78 3-4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120917067","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}

Using the proposed approach on 35 normal subjects and 10 arrhythmia patients, 100% verification rate was obtained for normal subjects and 81% verification rate for arrhythmia patients. Furthermore, the performance of the ECG verification system was evaluated by the false acceptance rate (FAR) and false rejection rate (FRR). The FAR was 0.83% and FRR was 0.86%for a database containing only 35 normal subjects. When 10 arrhythmia patients were added into the database, the FAR became 12.50% and the FRR 5.11%.

In order to provide ubiquitous services (u-Service) which deliver useful information to service users without human intervention, this paper implements a proactive information delivery system using Bluetooth technology. Bluetooth is a low- powered networking service that supports several protocol profiles, most importantly file transfer. Combined together, ubiquitous computing and Bluetooth have the potential to furnish ubiquitous solutions (u-Solutions) that are efficient, employ simplified design characteristics, and collaboratively perform functions they are otherwise not capable. Thus, this paper first addresses the current Bluetooth technology. Then, it suggests and develops the proactive information delivery system utilizing Bluetooth and ubiquitous computing network concepts.
