Smart radome improves reflector antenna directivity
A numerical optimization procedure is applied to two dimensional model of cylindrical reflector antenna arbitrarily located inside a circular cylindrical dielectric radome. If the radome thickness has been optimized, then ...
Automatic multimedia cross-modal correlation discovery
Given an image (or video clip, or audio song), how do we automatically assign keywords to it? The general problem is to find correlations across the media in a collection of multimedia objects like video clips, with colors, ...
Block SOR for Kronecker structured representations
The Kronecker structure of a hierarchical Markovian model (HMM) induces nested block partitionings in the transition matrix of its underlying Markov chain. This paper shows how sparse real Schur factors of certain diagonal ...
Paraxial space - domain formulation for surface fields on large dielectric coated circular cylinders
A space-domain represention for the surface fields excited by an elementary current source was discussed. Green's function was used and an approximation was made using Fourier series (FS), where FS coefficients were ...
Capacity bounds for an ultra-wideband channel model
There is an ongoing effort by the IEEE 802.15.3a subcommittee to reach a UWB personal area network standard. We estimate the achievable rates for such networks using a channel model specified by the same group. The analysis ...
