The workshop will consider the ways in which authority is distributed throughout the design process, what kind of authority inheres in design, and also the ways that we design authority into processes and materials. W...

Google has recently released the video compression format VP8 to the open source community. This new compression format competes against the existing H.264 video standard developed by the ITU-T Video Coding Experts Group (VCEG) in collaboration with the ISO/IEC Moving Picture Experts Group (MPEG). This paper compares these two video coding standards in terms of video bit rate-distortion (quality) performance and the video network traffic variability with different long video sequences. We find that VP8 presently does not fulfill its promise to achieve twice the quality at half the bandwidth compared to H.264. The rate-distortion (RD) performance of VP8 is rather slightly below the RD performance of H.264. On the positive side, in contrast to H.264, VP8 has no license fees.
In this paper we present an environment composed of two solutions offering a flexible combination of general public personalised e-Care Services according to user's preference or available ICT media, and at a seco...

Modern machine learning techniques have encouraged interest in the development of vehicle health monitoring systems that ensure secure and reliable operations of rail vehicles. In an earlier study, an energy-efficient data acquisition method was investigated to develop a monitoring system for railway applications using modern machine learning techniques, more specific classification algorithms. A suitable classifier was proposed for railway monitoring based on relative weighted performance metrics. To improve the performance of the existing approach, a rule-based learning method using statistical analysis has been proposed in this paper to select a unique classifier for the same application. This selected algorithm works more efficiently and improves the overall performance of the railway monitoring systems. This study has been conducted using six classifiers, namely REPTree, J48, Decision Stump, IBK, PART and OneR, with twenty-five datasets. The Waikato Environment for Knowledge Analysis (WEKA) learning tool has been used in this study to develop the prediction models.
This paper presents two approaches to achieve attentiveness of a virtual quiz agent in the interactions with multiple users at the same time. One attempts to improve the agent with an utterance strategy to determine w...

Mobile technology is becoming increasingly widespread in museums and cultural heritage sites, and many institutions have already developed applications that can be downloaded on mobile phones. Amongst these, iPhone Applications are certainly the most popular. The research briefly presented here describes the phases of the development of an iPhone application to interactively present the story of the people and places depicted on the Summer War of Osaka byo̅bu (traditional Japanese wooden folding screens) currently displayed at Osaka Castle Museum, Osaka City, Japan. The iPhone application will also be integrated with the Tiled Display Wall system of the Knowledge Creating Communication Research Center of NICT (Kyoto) to test various interaction functionalities.
