Optimal image restoration with the fractional Fourier transform
(OSA - The Optical Society, 1998-04)The classical Wiener filter, which can be implemented in O(N log N) time, is suited best for space-invariant degradation models and space-invariant signal and noise characteristics. For space-varying degradations and ... -
PDE control of a rotating shear beam with boundary feedback
(IEEE, 2009-08)We consider a flexible structure modeled as a shear beam which is clamped to a rigid body at one end and is free at the other end. The whole structure is free to rotate on the horizontal plane. We first model the system ... -
A robust approach for the derivation of closed-form Green's functions
(Institute of Electrical and Electronics Engineers, 1996-05)Spatial-domain Green's functions for multilayer, planar geometries are cast into closed forms with two-level approximation of the spectral-domain representation of the Green's functions. This approach is very robust and ... -
Scattering and absorption performance of a microsize graphene-based parabolic reflector in the THz range illuminated by a complex line source
(IEEE, 2017)The scattering and absorption characteristics of a two- dimensional (2-D) parabolic reflector made of graphene and placed in the free space is simulated using the Method of Analytical Regularization (MAR) technique. Reflector ... -
Structured least squares with bounded data uncertainties
(IEEE, 2009)In many signal processing applications the core problem reduces to a linear system of equations. Coefficient matrix uncertainties create a significant challenge in obtaining reliable solutions. In this paper, we present a ... -
Switching resilient PI controllers for active queue management of TCP flows
(IEEE, 2007)Active Queue Management (AQM) is used in computer networks to increase link utilization with less queueing delays. The fluid flow model or TCP based on delay differential equations supplies the mathematical background for ...
