Unbalanced Multiple-Description Video Coding with Rate-Distortion Optimization
EURASIP Journal on Advances in Signal Processing, 2003 We propose to use multiple-description coding (MDC) to protect video information against packet losses and delay, while also ensuring that it can be decoded using a standard decoder.

Advanced Functional Materials, EarlyView.Forming‐free epitaxial Pt/La0.5Sr0.5CoOx (LSCO)/La0.5Sr0.5MnO3 (LSMO) memristors exhibit heterogeneous and partially reversible topotactic switching involving brownmillerite (BM)‐, Grenier (GN)‐like‐, and perovskite (PV)‐like configurations. Atomic‐resolution scanning transmission electron microscopy and in situ transmission electron microscopy resolve

Linked Data based video annotation and browsing for distance learning [PDF]
, 2010 We present a pair of prototype tools that enable users to mark up video with annotations and later explore related materials using Semantic Web and Linked Data approaches. The first tool helps academics preparing Open University course materials to mark

Distributed Temporal Multiple Description Coding for Robust Video Transmission
EURASIP Journal on Wireless Communications and Networking, 2008 The problem of multimedia communications over best-effort networks is addressed here with multiple description coding (MDC) in a distributed framework. In this paper, we first compare four video MDC schemes based on different time splitting patterns and ...

Magneto‐Ionic Devices With Polymer‐Based Electrolytes
Advanced Functional Materials, EarlyView.Polymer electrolytes are introduced for magneto‐ionic devices based on hydroxide and hydrogen ions. The magneto‐ionic effect results in a pronounced voltage‐controlled variation of coercivity in both devices. The switching speed is in the range of 100 ms.
