Khaled A . Harfoush

INTERESTS My main research interest is to develop end-to-end network diagnosis techniques to uncover dynamic network properties (e.g. congestion information, bottleneck equivalence, loss rates, topology, etc.) in a near real-time fashion. This information can be used to characterize the Internet dynamics and to dynamically adapt the control strategies of massively accessed Web servers (e.g. con...

Algorithm for Modulo Addition KHALED

When designing elliptic-function filters there is usually some margin in performance to be distributed over the defining parameters. A recent paper offered some comparatively complicated formulas for use in this stage of the design. However, a simpler method, originally due to Darlington, is available and i s described briefly. passband ripple is again given by (2). ‘The cd function is the same...
