    • Design implementation and evaluation of a tablet-based student response system for an engineering classroom 

      McLoone, S.C.; O'Keeffe, S.; Villing, R. (Signals and Systems Conference (ISSC 2013), 24th IET Irish, 2013-06)
      Student response systems (SRSs) have generated significant debate and discussion in the educational research literature in the past decade. It is well known that they offer several important advantages including encouraging ...

    • Optimizing area power consumption in LTE type cells 

      Keenan, T.; Villing, R. (Signals and Systems Conference (ISSC 2013), 24th IET Irish, 2013-06)
      As wireless networks evolve to deal with increasing traffic demand and an increasing number of users, energy efficiency is becoming increasingly important. Area power consumption, defined as the ratio of total radio access ...

    • Comparing and contrasting smartphone and non-smartphone usage 

      Carolan, E.; McLoone, S.C.; Farrell, R. (Signals and Systems Conference (ISSC 2013), 24th IET Irish, 2013-06)
      This paper presents a large-scale network wide analysis of both user behaviour and network dynamics in a live nationwide 2G/3G network. The employed data set tracks over one million subscribers across upwards of ten thousand ...

    • 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 ...

    • Prototype test insertion co-processor for agile development in multi-threaded embedded environments 

      Dongcheng, Deng.; Smith, M.; Miller, J. (Signals and Systems Conference (ISSC 2013), 24th IET Irish, 2013-06)
      Agile methodologies have been shown useful in constructing Enterprise applications with a reduced level of defects in the released product. Movement of Agile processes into the embedded world is hindered by the lack of ...

    • Impact of DFT properties on the inherent resolution of compressed sensing reconstructed images 

      Smith, M.; Woehr, J.; Marasco, E.; MacDonald, M.E. (Signals and Systems Conference (ISSC 2013), 24th IET Irish, 2013-06)
      Compressed sensing (CS) algorithms exploit sparseness properties to reconstruct high spatial resolution magnetic resonance (MR) images from k-space data acquisitions significantly under sampled to reduce imaging times. CS ...

    • Control of open-loop unstable processes with time delay using PI/PID controllers specified using tuning rules: An outline survey 

      O'Dwyer, A. (Signals and Systems Conference (ISSC 2013), 24th IET Irish, 2013-06)
      The ability of PI and PID controllers to compensate many practical processes has led to their wide acceptance in industrial applications. The requirement to choose two or three controller parameters is conveniently done ...

    • 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) ...

    • 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 ...
