    • 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) ...
    • Reliable system design with a high degree of diagnostic procedures for embedded systems 

      Schwarz, M.H.; Borcsok, J. (Signals and Systems Conference (ISSC 2013), 24th IET Irish, 2013-06)
      Maintenance starts with reliable diagnostics. Programming Logic Controllers (PLCs) are often equipped with a high degree of diagnostic procedures in order to ensure that the processing unit is functioning correctly. It is ...
    • Replicating reality: Driver assessment using dual-fidelity simulator 

      Kaneswaran, D.; Brogan, M.; Mulcahy, M.; Commins, S.; Deegan, C.; Markham, C. (Signals and Systems Conference (ISSC 2013), 24th IET Irish, 2013-06)
      This paper presents a driving simulator constructed for the purposes of allowing a direct comparison between two levels of fidelity in the driver interaction stream. The driving simulator itself is described, followed by ...
    • Robust digital video watermarking using reversible data hiding and visual cryptography 

      Kumar, M.; Hensman, A. (Signals and Systems Conference (ISSC 2013), 24th IET Irish, 2013-06)
      Watermarking is a major image processing application used to authenticate user documents by embedding and hiding some authenticated piece of information behind an image, audio or the video file. For example, copyright ...
    • A simplified approach to perceptual quality adaptation of multi-dimensional scalable video 

      Maddodi, G.; Lee, B.; Yuansong, Qiao. (Signals and Systems Conference (ISSC 2013), 24th IET Irish, 2013-06)
      Content Aware Networking (CAN) can enhance the distribution of media through awareness in the network of the content it is carrying. In this way functions such as content adaptation, content routing and resource allocation ...
    • Towards shifted NMF for improved monaural separation 

      Jaiswal, R.; Fitzgerald, D.; Coyle, E.; Rickard, S. (Signals and Systems Conference (ISSC 2013), 24th IET Irish, 2013-06)
      The ability of Non-negative Matrix Factorisation (NMF) to decompose magnitude spectrogram into meaningful entities has found use in many audio applications. NMF can be used to factorise audio spectrogram of a music signal ...
    • Vehicle speed estimation using GPS/RISS (Reduced Inertial Sensor System) 

      O'Kane, T.; Ringwood, J.V. (Signals and Systems Conference (ISSC 2013), 24th IET Irish, 2013-06)
      Land vehicle speed is usually measured by wheel speed or GPS. While these methods are adequate for some purposes, there are some drawbacks. Wheel speed may differ greatly from vehicle speed due to tyre slip. In addition, ...
    • Wireless communication using ultrasound in air with parallel OOK channels 

      Wentao, Jiang.; Wright, W.M.D. (Signals and Systems Conference (ISSC 2013), 24th IET Irish, 2013-06)
      The use of airborne ultrasonic transducers for wireless communication was demonstrated. The work used capacitive ultrasonic transducers to transmit coded binary signals through parallel air channels. On-Off Keying modulation ...
    • Wireless sensed environment for body area networks 

      McDaid, C.; Timmons, N.; Morrison, J. (Signals and Systems Conference (ISSC 2013), 24th IET Irish, 2013-06)
      In low power wireless body area networks it is envisaged that there will be communication between on-body devices and wireless nodes placed in the environment (sensed environment) to provide a range of applications including ...
