The problem of scheduling strictly periodic tasks, that is tasks that have to be executed at constant time intervals over an infinite time horizon, naturally arises in real-time video signal… Expand
Flow-level modelling of TCP traffic using GPS queueing networks
- O. Brun, A. A. Sheikh, J. Garcia
- Computer Science
- 21st International Teletraffic Congress
- 30 October 2009
We develop flow-level models of TCP/IP networks. We first consider access network models in a very general framework where Internet subscribers can use several types of TCP-based applications and may… Expand

AN ADAPTIVE CONTROL FOR TIKHONOV REGULARIZATION ON UNSTRUCTURED GRID FOR A VARIATIONAL DENOISING PROBLEM
- Khuda bux Amur, Syed Fahad Allam Shah, Ahmad Al Sheikh
- Computer Science
- 15 September 2013
A local adaptive control of regularization for a denoising problem is proposed in this article. Our goal is to solve a linear variational denoising problem which is based on the idea of Tikhonov… Expand
