    • Cryptography using evolutionary computing 

      Blackledge, J.; Bezobrazov, S.; Tobin, P.; Zamora, F. (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 ...

    • Near-field radiation patterns for an Ultra-Wide-Band antenna 

      Blackledge, J.; Babajanov, B. (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 ...

    • On the application of two dimensional chirplets for resilient digital image watermarking 

      Blackledge, J.; Iakovenko, O. (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 

      Woolmington, T.; Sunderland, K.; Blackledge, J.; Conlon, M. (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) ...
