![]() ![]() The parallel multiprocessor systems should be so designed The two major issues in the formulation andĭesign of parallel multiprocessor systems are algorithm design and architecture design. Power of sequential uniprocessor systems have lead to the development of parallel multiprocessor systems. Inherent limitations on the computational In order to convert data to knowledge, it is necessary to search (+process) data sets that are on the order of zettabytes in size (Big Data).Ĭonventional computers (uniprocessor systems) are unable to process Big Data in a timely manner. Then, several solutions at the various layers will be presented, which include application, RTP/UDP and RTP/TCP, MAC, and physical layers.įinally, the talk will conclude with open research issues and future directions. This talk first introduces the basic concepts of WHDVT, which include characteristics of 802.11 networks, H.264 video compression, and video streaming protocols. These include lossy and delay prone nature of wireless media, unequal importance of video packets, and user mobility. Will need to be supported on the same network. However, significant challenges exist in delivering smooth playback of HD content as WHDVT becomes more pervasive and multiple streams Wireless High Definition Video Transmission (WHDVT) over 802.11-based networks is an important enabling technology for home networks, viewing videos on the move,Īnd N-screen environments. Wireless HD Video Transmission Technology: Challenges and Future Applications Reflecting on the past 15 years, I will also point to a set of continuing challengesĪnd opportunities for interdisciplinary study that is founded on the integration of the information sciences, an increasingly ubiquitous technological substrate, and the broad and ambiguous implications of human individualsĪnd organizations situated in real world activities. Illustrated throughout with examples drawn from education and research activities at Penn State and other iSchools. In this talk, I will give a brief history of how and why this new realm of academic pursuits has emerged, The Pennsylvania State University was one the first iSchools, launched in 1998 to meet the needs for workforce development of students who have the skills of information technologyīut also to research topics in real world interdisciplinary computing. The emergence of iSchools has been much discussed, with respect to an interdisciplinary vision for both research and education of undergraduate and graduate students. The iSchool Vision for Interdisciplinary University Research and Education Or help seekers who need more assistance.Ĭollege of Information Sciences and Technology Mediators or facilitating just-in-time adaptation to discussants' needs, such as identifying unresolved issues The analysis results are used for assisting discussion In particular, we present a computational workflow (big data) framework that enables efficientĪnd robust integration and analyses of diverse datasets. ![]() In the latter part of the presentation, we show how such analyses can be a powerful tool for dialogue mediatorsĪnd participants. Such role information can be used for promoting interactions among potential peer collaborators. We show how the role information can be combined with linguisticĪnd temporal features for developing a predictive model of discussant performance. We also identify user intent in the discussion as an Such as question, answer or acknowledgement. We present a model for capturing information seeking or information providing roles of messages, We first analyze how messages and individual discussants contribute to Q&A discussions. This talk present our work on online discussion modeling and intelligent tools for assisting discussion Support and promote effective interactions and participation. Within online communication and collaboration environments, and develop computational tools that In various fields, including science, politics, and education. Social software such as online forums, Wikis, and social networking sites, plays an important role ![]()
