Dynamic Bandwidth Management in Distributed VoD based on the User Class Using Agents [PDF]

International Journal of Computer Science and Information Security, IJCSIS, July 2009, Volume 3. No.1, USA, 2009
This paper proposes a dynamic bandwidth management algorithm in which more bandwidth is allocated for higher class users and also higher priority is given to the videos with higher popularity within a class using agent technology. The popularity and weight profile of the videos which is used for efficiently allocating bandwidth is periodically updated ...

Ultrafast Room‐Temperature Nanofabrication via Ozone‐Based Gas‐Phase Metal‐Assisted Chemical Etching for High‐Performance Silicon Photodetectors

Advanced Functional Materials, EarlyView.
Ozone‐based gas‐phase metal‐assisted chemical etching enables unprecedented room‐temperature fabrication of high‐quality silicon nanowires. The superior oxidation potential of O3 drives rapid vertical etching (1 µm min−1) while maintaining exceptional structural integrity. The pristine nanowire surfaces enable high‐performance core‐shell photodetectors

Transient Stiffness Patterning in Hydrogels Driven by Dissipative Mechanochemical Coupling

Advanced Functional Materials, EarlyView.
Force‐induced disulfide bond rupture in a polymer‐based hydrogel, coupled with chemical or electrochemical reoxidation, leads to the transient modulation of the hydrogel's stiffness properties. High spatiotemporal control is achieved by this dissipative process, enabling the development of out‐of‐equilibrium stiffness patterns and transient, dose ...
