The wide-spreading handheld devices with various free and easily downloadable applications make multimedia streaming services provided everywhere. Multimedia streaming data like video are compressed such that successive frames may have different sizes, and then each frame transmission is a burst with a different size. The service of delivering video is then classified as of variable bit rate (VBR). It is not easy for traffic control on VBR services. The resource utilization may be reduced if too much resource is reserved for a video stream, or video playing may be paused due to improper or less resource reservation. For these reasons, there has been some related work that makes video-on-demand (VOD) streams transmitted in constant bit rates (CBR). It will then reduce some overhead in traffic control and provide better quality of services. Besides designing suitable signaling protocols for resource reservation in LTE/LTE-A, accurate estimation of resource that should be reserved is another important topic for CBR-based transmission. In this paper, a feasible computation for minimal resource requirements is proposed for CBR multimedia streaming services in QoS enhanced LTE/LTE-A networks.","PeriodicalId":174849,"journal":{"name":"2014 7th International Conference on Ubi-Media Computing and Workshops","volume":"403 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126878689","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}

It utilizes information such as the best mode and the rate value of the RD cost function, which are all pre-calculated. These values are calculated in the corresponding macro block (MB) of the previous frame and the neighbouring MBs of the current frame in order to develop an intra skip decision rule. Our experimental results demonstrated that without the additional time-consuming computation, the proposed algorithm reduces encoding time by approximately 50% compared with the time needed for an exhaustive search and it significantly increases the time saving by 17%-30% compared with the existing algorithms. In addition, our experimental results showed that the differences in peak signal-to-noise ratio degradation are negligible and the bit rate increment is minimal.","PeriodicalId":174849,"journal":{"name":"2014 7th International Conference on Ubi-Media Computing and Workshops","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121900213","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}

Kinect, the 3D sensing device introduced by Microsoft which allows developers to use depth data for research. Recently, there are several mature libraries such as NITE and Kinect SDK which provide functions of Human skeleton tracking. Therefore, users may find that these applications only work with big joints of human body. When it comes to the tracking of fingers, devices such as Leap Motion will be mentioned because it provides APIs and games, which users can communicate with the computer by their fingers. Although Leap Motion Provides functions of finger tracking, the operating distance is short and users need to sit in a fixed position. Here, in this paper, authors' experimental efforts on detailed hand tracking including fingers based on Microsoft Kinect.

This negates opportunities which exist when ICT are deployed along the supply chain to provide feedback to the strategic layers for optimisations that improve efficiencies and reduce costs. The wood supply chain is largely based in the \"environment\": forests, roads, or mills and there is much to be gained by integrating ICT within these areas. Our experience working within the Cooperative Research Centre for Forestry (CRCF) has been that ICT systems have been developed with limited for sight around their long term sustainability: lack of consideration around the system in its context of use, placing the onus on the user to learn to adapt their work practises for system usage. This paper proposes applying design approaches found within ubiquitous computing to avoid the above shortcomings. Here the Smart Device Environment Integration (DEI) Model is applied to conceptually explore the benefits of applying a systematic approach to forestry systems design. One outcome is the design process is made easier, another is a more complete understanding of system robustness and the limitation for system acceptance from user-centric points of view.","PeriodicalId":174849,"journal":{"name":"2014 7th International Conference on Ubi-Media Computing and Workshops","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124699693","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}

This mechanism provides some advantages for general data analysis. With the same concept Apache Sqoop separates each table into four parts and randomly distributes them on data nodes. However, there is still a database performance concern with this data placement mechanism. This paper proposes a Correlation Aware method on Sqoop (CA_Sqoop) to improve the data placement. By gathering related data as closer as it could be to reduce the data transformation cost on the network and improve the performance in terms of database usage. The CA_Sqoop also considers the table correlation and size for better data locality and query efficiency. Simulation results show that data locality of CA_Sqoop is two times better than that of original Apache Sqoop.","PeriodicalId":174849,"journal":{"name":"2014 7th International Conference on Ubi-Media Computing and Workshops","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123146500","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}
