Low delay audio coding based on logarithmic spherical vector quantization
… and often contradictory constraints are a low algorithmic delay, a high perceived quality for speech as well as for audio signals at low bit rates and a low computational complexity. State-of-the-art standardized approaches for digital lossy source coding in general either have a high …

A Framework for Designing a Low-Loss, Low-Delay Internet
Finally, we present a simple Active Queue Management scheme that we call the Adaptive Virtual Queue (AVQ) algorithm and provide design rules for selecting its parameters. We also provide a simple implementation of the AVQ scheme using a token-bucket formulation, which can be implemented with a few …

Distributed optimization of traffic delay on a periodic switched grid network
… each unit (car or packet) accumulates some delay while traversing the network. This delay is undesirable but unavoidable, which makes minimizing the total average delay of the network given certain constraints, a desirable objective. In this work, we consider the case of periodic networks, …
