  • Advances in networked Media - Theory and practice
    2003 IEEE International Conference on Acoustics Speech and Signal Processing 2003. Proceedings. (ICASSP '03)., 2003
    Co-Authors: Ya-qin Zhang
    Abstract:

    Summary form only given. We have witnessed the increasing convergence of digital Media, wireless and networking technologies in the past decade. This has profoundly transformed the way Media is being represented, processed, delivered, and presented. For over half a century, Shannon's rate-distortion (R-D) Theory has been the theoretical foundation for information representation. With the emergence of new Media, devices and applications in networked environment, the conventional R-D Theory needs to be extended to enable more effective representation and processing of connected Media. This article summarizes our attempt to develop a 'networked R-D Theory' as well as some initial applications. In particular, it addresses the following research initiatives currently undertaken by Microsoft Research Asia: (a) new sampling and rendering structure for computer graphics and digital ink; (b) Media delivery over a network with errors, congestion, retransmission, and multi-user interaction; (c) and Media summarization where maximum information could be extracted for a given time boundary. Some of these technologies have already been transferred into Microsoft's mainstream products, which will help enable a plethora of applications such as high-quality Media streaming, intelligent note-taking, networked games, and home audio/photo/video editing.

  • Porous Media Theory: A survey
    Zamm-zeitschrift Fur Angewandte Mathematik Und Mechanik, 2020
    Co-Authors: R. De Boer
    Abstract:

    Recently some important new findings in the porous Media Theory have been worked out and partly published, which has led to a widely consistent Theory. Thus, the time seems to be ripe to give a survey of the current state of the porous Media Theory.

  • Introduction to the Porous Media Theory
    Solid Mechanics and Its Applications, 2020
    Co-Authors: R. De Boer
    Abstract:

    In this paper the current state of the macroscopic porous Media Theory has been stated along with the citation of numerous contributions. The investigations concerning the fundamentals of the Theory of porous Media have revealed that in the last decade a consistent Theory has been derived, consistent with the basic principles of continuum mechanics, in particular, the dissipation principles.

  • The volume fraction concept in the porous Media Theory
    Zamm-zeitschrift Fur Angewandte Mathematik Und Mechanik, 1997
    Co-Authors: Joachim Bluhm, R. De Boer
    Abstract:

    In this paper the volume fraction concept in the porous Media Theory is considered. First, the historical development of this important concept is traced. Thereupon, the concept of volume fractions is formulated and the transport theorems, which govern the transformations of volume elements from one placement to another, are derived. An essential feature is the incorporation of the effect of incompressibility into the transport theorems. This is only possible by the introductions of a new multiplicative decomposition of the deformation gradients of the constituents into parts describing the deformations of the realistic (true) materials and parts including the changes of the poles.

  • Mind the Gap: On Actor-Network Theory and German Media Theory
    Advances in Media Entertainment and the Arts, 2020
    Co-Authors: Veronika Pöhnl
    Abstract:

    This chapter discusses similarities of and differences between the epistemological premises of ANT and “German Media Theory”. The applicability of ANT for Media investigations and the compatibility of ANT concepts in Media Studies have been discussed intensively for several years now. The profound similarities as well as the critical differences in the study of the material conditions of human culture have also stimulated current reconsiderations and reformulations in “Cultural Media Studies,” as German Media Theory is most commonly called in Germany. The following article gives a brief overview on most recently published approaches to cultural techniques and intersections of Media and techno-philosophy that are increasingly being translated into English and therefore also internationally accessible, alongside with the discussion concerning their compatibility with ANT.

  • Transportation, Transformation, and Metaphoricity: Concepts of Transmission in ANT and German Media Theory
    Advances in Human and Social Aspects of Technology, 2020
    Co-Authors: Veronika Pöhnl
    Abstract:

    This chapter discusses similarities of and differences between the epistemological premises of ANT and German Media Theory concerning concepts of transmission. The applicability of ANT for Media investigations and the compatibility of ANT concepts in Media studies have been discussed intensively for several years now. The profound similarities as well as the critical differences in the study of the material conditions of human culture have also stimulated current reconsiderations and reformulations in cultural Media studies, as German Media Theory is most commonly called in Germany. The chapter gives a brief overview of recently published approaches to cultural techniques and intersections of Media and techno-philosophy that are increasingly being translated into English and therefore also internationally accessible, alongside with the discussion concerning their compatibility with ANT in respect of cultural transmission.
