On-the-fly erasure coding for real-time video applications
... In the presence of VBR sources as video, this behavior is furthermore confirmed as FEC schemes lack adaptability compared to Tetrys. Indeed, recovering from a given number of losses means waiting for the reception of (at ...

Hecke algebras with unequal parameters and Vogan's left cell invariants
... Abstract. In 1979, Vogan introduced a generalised τ -invariant for charac- terising primitive ideals in enveloping algebras. Via a known dictionary this translates to an invariant of left cells in the sense of Kazhdan ...
