  • feed forward buffering and rate control based on scene change featureslll for mpeg video coder
    European Signal Processing Conference, 1996
    Co-Authors: Yoosok Saw, P M Grant, J M Hannah
    Abstract:

    Video traffic management has been a challenging task in the fields of network management and multi-Media Communication. Transmission buffering is widely used to smooth bursty traffic and maintain a steady traffic level by adapting the incoming source traffic to the buffer. This paper describes an efficient adaptive buffering scheme which is based on feed-forward control to adaptively handle the non-stationary nature of bursty video traffic. The performance of a series of quantisation scale mapping curves is presented in terms of occupancy and video quality.

The term "traffic" is used to indicate the time-varying nonstationary nature of the video bit stream, since the video can alter from still to moving pictures. In applications using transmission buffer, overflow and congestion may take place in bursty traffic or a low bit-rate CBR (constant bit rate) channel. While muc..

  • a learning collaboration between engineering and journalism undergraduate students prompts interdisciplinary behaviour
    Advances in engineering education, 2011
    Co-Authors: Lydia Kavanagh, John Cokley
    Abstract:

    Final-year university engineering and journalism undergraduate students collaborate in a multiMedia design and Communication project to test the hypothesis that design and Communication emphasis by engineering students can be enhanced by interdisciplinary collaboration with Media-equipped journalism students. Research was conducted by environmental manipulation, observation, administration of a survey, and qualitative and quantitative analysis of Media products. Participants reported increased Media Communication skills, an awareness of the necessity of communicating with other disciplines, and some change in their intended strategies for future projects. Evaluative instruments recorded a high level of student satisfaction with the collaboration. Evidence was obtained of a close relationship between engineering education and journalism education, leading to a level of interdisciplinarity among student participants.

  • toward a typology of government social Media Communication democratic goals symbolic acts and self presentation
    Government Information Quarterly, 2017
    Co-Authors: Nic Depaula, Ersin Dincelli, Teresa M Harrison
    Abstract:

    Abstract Social Media have provided new environments for both individuals and organizations to communicate. The literature on government use of social Media has noted that these platforms provide a variety of democratic functions for government institutions, in their ability to increase transparency and citizen participation. However, there is less recognition and understanding in this context about the symbolic and presentational content governments communicate on social Media. This is the case despite the fact that social Media are tools for self-presentation, the exchange of symbolic content, and marketing. We have conducted a literature review from diverse sources, including e-government, business, human-computer interaction, social psychology and human Communication to develop a typology of government Communication on social Media. We present a classification scheme with 12 specific categories and discuss the potential purposes of these various types of Communication. Via empirical content analysis, we code a total of 2893 Facebook posts of local governments across the U.S., in a pilot and in a confirmatory study. This analysis allows us to better understand the categories of Communication and the extent of their presence. Although we find that most content on local government Facebook pages falls into the category of democratic information provision, almost half of all messages refer to symbolic and presentational types of information exchanges. We illustrate our results with examples, and present a discussion of these findings with implications for practitioners and future research.
