Some work has considered the joints of the humanoid robot like an arborescent structure, other as closed or open joint chain. Modeling methods are also different: the method of Denavit Hartenberg, the notion of modeling (father-child) uses the equation of Rodrigues and the method of state space [1]. The work presented in this article, is interested in modeling of a humanoid robot with 18 degree of freedom (DOF), three DOF in each arm and six DOF per foot.","PeriodicalId":369113,"journal":{"name":"Second International Conference on the Innovative Computing Technology (INTECH 2012)","volume":"1940 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129301844","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}

Nevertheless, the design of all these protocols does not take into account that group members may be mobile. Indeed, with the arrival of Mobile IPv6 by IETF providing mobile users with continuous access, group members in the network are very dynamic affecting on the quality of both routing protocol scheme and multicast tree used. The key idea of this work is to make the handover of multicast members transparent and avoid the reconstruction of the entire multicast-based tree, by using an architecture MC-PIM-SM based in PIM-SM multicast routing protocol with Multiple Cores Shared Multicast Tree to hide the mobility of mobile multicast members from the main multicast delivery tree. Simulation results show that good performance is achieved in terms of handoff latency, end-to-end delay, tree construction delay and others metrics.","PeriodicalId":369113,"journal":{"name":"Second International Conference on the Innovative Computing Technology (INTECH 2012)","volume":"2014 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130150214","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 popularity scores are used to rank query results when presented to the user. PageRank assigns to a page a score proportional to the number of times a random surfer would visit that page, if it surfed indefinitely from page to page, following all outlinks from a page with equal probability. Thereupon, several algorithms are introduced to improve the last one. In this paper, we introduce a more intelligent surfer model based on combining ontology, web contents and PageRank. Firstly, we propose a relevance measure of a web page relative to a multiple-term query. Then, we develop our performed intelligent surfer model. Efficient execution of our algorithm in a local database is performed. Results show that our algorithm significantly outperforms the existing algorithms in the quality of the pages returned, while remaining efficient enough to be used in today's large search engines.","PeriodicalId":369113,"journal":{"name":"Second International Conference on the Innovative Computing Technology (INTECH 2012)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129196306","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}

We propose a two steps algorithm that does not impose any constraints on the scene. The purpose of the first step is the extraction of a convenient “Projective Reconstruction” using a simple method. Indeed, it firstly initializes the projective calibration of the scene and then refines it using non-linear optimization. The extracted reconstruction is then integrated in the second step consisting on the upgrade of the reconstruction to a metric one; this is done through the research of the camera intrinsic parameters necessary for the upgrade stage. A multi-stage auto-calibration algorithm is proposed to iteratively estimate each parameter alone and finally refines all of them at once. Once these parameters are obtained, the 3D Euclidean reconstruction of the scene is extracted using a publicly available Multi-View Stereo software.","PeriodicalId":369113,"journal":{"name":"Second International Conference on the Innovative Computing Technology (INTECH 2012)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115849846","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}

Burst retransmission is a reactive loss recovery mechanism that attempts to resolve contention by retransmitting the contended burst at the optical burst switching layer. Burst cloning is a proactive loss recovery mechanism that attempts to prevent burst loss by sending two copies of the same burst, if the first copy is lost, the second copy may still be able to reach the destination. Burst retransmission is better suited when the load is low, however burst cloning is better suited when the load is high. In this paper, we propose a hybrid scheme for star OBS networks that combines the advantages of burst retransmission at low load with the benefits of burst cloning at high load through a decision algorithm which aims to control the extra load due to the both loss recovery mechanisms. The results obtained from simulation confirm that our hybrid scheme through the decision algorithm can achieve better overall network performance than both burst retransmission scheme and burst cloning scheme.","PeriodicalId":369113,"journal":{"name":"Second International Conference on the Innovative Computing Technology (INTECH 2012)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116657287","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}

However, biometric systems based on the storage of user model in a database are vulnerable to attacks because the stored model can be stolen or illegitimately used by an attacker to impersonate the user. To protect the users templates from attacks, two broad categories of methods are proposed in the literature: Transformation Biometric Characteristics, and Biometric Cryptosystems. Although biometric cryptosystems are used in several applications (e.g. smart cards), their major challenge is the lack of a security analysis and the limitation of the work on attacks against this type of methods. Hence the aim of this paper is to present criteria for security analysis and to demonstrate the vulnerability of Fuzzy Vault method; a famous approach in biometric cryptosystems.","PeriodicalId":369113,"journal":{"name":"Second International Conference on the Innovative Computing Technology (INTECH 2012)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127206886","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}
