On the application of two dimensional chirplets for resilient digital image watermarking
(Signals and Systems Conference (ISSC 2013), 24th IET Irish, 2013-06)
Chirplets (swept-frequency harmonic signals) find applications in several areas, including real and synthetic aperture radar, (Fresnel) optics and image processing. The robustness of chirplets to extreme (additive) noise ...
The quantification of wind turbulence by means of the fourier dimension
(Signals and Systems Conference (ISSC 2013), 24th IET Irish, 2013-06)
Signal Processing within the frequency domain has long been associated with electrical engineering as a means to quantify the characteristics of voltage/current waveforms. Historically, wind speed data (speed/direction) ...
Near-field radiation patterns for an Ultra-Wide-Band antenna
(Signals and Systems Conference (ISSC 2013), 24th IET Irish, 2013-06)
We present a three-dimensional time dependent model for simulating the electromagnetic radiation field patterns generated by Ultra-Wide-Band (UWB) antennas. UWB antennas are pulsed mode radiators used to communicate ...
Cryptography using evolutionary computing
(Signals and Systems Conference (ISSC 2013), 24th IET Irish, 2013-06)
We present a method of generating encryptors, in particular, Pseudo Random Number Generators (PRNG), using evolutionary computing. Working with a system called Eureqa, designed by the Cornell Creative Machines Lab, we seed ...
