Comparison of HEVC coding schemes for tile-based viewport-adaptive streaming of omnidirectional video

Virtual reality applications make use of 360-degree panoramic or omnidirectional video with high resolution and high frame rate in order to create the immersive experience to the user. The user views only a portion of the captured 360-degree scene at each time instant, hence streaming the whole omnidirectional video in ...

  • Hu T.
  • Scott G.

We present low temperature transport measurements of C60-based single molecule transistors fabricated using ferromagnetic break junction devices with planar elliptical leads, revealing a gate-modulated single channel spin-1/2 Kondo effect. The shape anisotropy and dipole interaction of the source and drain electrodes allows for the relative alignment of their respective magnetic ...

Investigating activity zones on smartphones: An empirical study with older adults

This paper investigates and extends existing knowledge on older adults' (65+) gestural interaction with smartphones. Specifically, it looks at the effect touch targets location has on older adults' performance of tap and swipe gestures. Two separate experiments, each with 40 participants, showed older adults' performance for tap is best toward ...

Edge Computing in the ePC --- A Reality Check

  • Abe Y.
  • Hadzic I.
  • Woithe H.

Mobile Edge Computing (MEC) has received much attention from the research community in recent years. A significant part of the published work has studied the telecom-centric MEC architecture, which assumes that the computing resource is located at the edge of the mobile access network (e.g., the Evolved Packet Core), typically ...
