Most of rate-control research focuses on inter-coded frames, instead of intra-coded frames which are more possible to cause the problem of buffer overflow. This letter presents a rate control algorithm for intra-frame coding. We propose a Taylor-series-based rate-QS model and a scene-change aware rate-QS model to determine quantization parameters for general intra-frames and scene-change frames, respectively...
Finite positions method is presented in this paper for complete balancing of shaking forces for planar and spatial mechanisms as well as the solutions to its equations. By using the method, only correctly formulated single-linked-chains (SOC) with proper connection and leaf components are needed to substitute into the equations to solve the parameters, which will be used to fully balance the shaking...
Background traffic has a significant impact on the behavior of network services and protocols. However, a detailed model of the background traffic can be extremely time consuming in simulation. In this paper, we extend our previous hybrid model that combines fluid and packet-oriented characterization of network traffic for a realistic representation of the background traffic on Internet. In particular,...
