    Sammanfattning : With emerging technologies such as high-definition video, virtual reality, and cloud computing, bandwidth demand in the access networks is ever-increasing. Passive optical network (PON) has become a promising architecture thanks to its low cost and easy management. LÄS MER

  4. 3. High-speed stereo imaging for the characterization of anisotropic viscoelastic media

    Författare :Luca Manzari; Peter Göransson; Jacques Cuenca; Ines Lopez Arteaga; Mathieu Aucejo; KTH; []
    Nyckelord :Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : This thesis proposes an experimental method for observing and characterizing the viscoelastic properties of anisotropic media using high-speed white light stereo imaging. The method uses short-time video recordings of a specimen undergoing forced harmonic motion. LÄS MER

  5. 4. Live Mobile Video Interaction : Inventing and investigating technology, formats and applications

    Författare :Mudassar Ahmad Mughal; Oskar Juhlin; Gina Venolia; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; human computer interaction; liveness; live; ambient video; mobile webcasting; Computer and Systems Sciences; data- och systemvetenskap;

    Sammanfattning : The convergence of inexpensive video-enabled mobile phones, high-speed mobile data networks and ubiquitous sensing devices opens up a new design space called “live mobile video interaction”. It gives rise to a new genre of applications concerning live mobile video production, which can be seen as an instance of the said space. LÄS MER

  7. 5. Study of Six-Port Modulators and Demodulators for High-Speed Data Communications

    Författare :Joakim Östh; Shaofang Gong; Magnus Karlsson; Robert Weigel; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : There is an increasing demand for high-speed wireless data communications to support consumers’ need for, among other things, real time streaming of high definition video and fast file transfers. One radio architecture that has a potential to meet the increasing demand for high-speed data communications is a radio technique based on the six-port architecture. LÄS MER
