    • 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 ...

    • 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 ...

    • Improved stereo instrumental track recovery using median nearest-neighbour inpainting 

      Jaiswal, R.; Fitzgerald, D. (Signals and Systems Conference (ISSC 2013), 24th IET Irish, 2013-06)
      Several algorithms have been proposed for vocal removal which operate by finding the position of the vocals in the stereo field and removing the time-frequency bins associated with that position. However, in many cases, ...

    • 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 ...

    • 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 ...

    • Error-free authentication watermarking based on prediction-error-expansion reversible technique 

      Rongrong Ni; Cheng, H.D.; Yao Zhao.; Yu Hou. (Signals and Systems Conference (ISSC 2013), 24th IET Irish, 2013-06)
      Watermarking technology is an efficient method to protect multimedia content. In this paper, an error-free authentication watermarking is proposed based on prediction-error-expansion reversible technique. A binary image ...

    • Ghostbusters: A parts-based NMF algorithm 

      de Frein, R. (Signals and Systems Conference (ISSC 2013), 24th IET Irish, 2013-06)
      An exact nonnegative matrix decomposition algorithm is proposed. This is achieved by 1) Taking a nonlinear approximation of a sparse real-valued dataset at a given tolerance-to-error constraint, c; Choosing an arbitrary ...

    • 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 ...

    • Extraction of reliability indicators from large-scale, highly variable timing data of MEMS switches 

      Kosla, C.; Hill, M. (Signals and Systems Conference (ISSC 2013), 24th IET Irish, 2013-06)
      In this paper we present a method for monitoring and processing large-scale highly variable and nonlinear reliability data for MEMS RF Switches. The data is generated by measuring the switch actuation dynamics and a ...

    • Motion-onset visual evoked potentials for gaming: A pilot study 

      Marshall, D.; Coyle, D.; Wilson, S. (Signals and Systems Conference (ISSC 2013), 24th IET Irish, 2013-06)
      This paper details a pilot study for a motion onset Visual Evoked Potential (mVEP) based Brain Computer Interface (BCI) controlled game. mVEP is a type of VEP that uses visual responses from the dorsal pathway of the visual ...

    • Detection and characterization of acoustic signals from a granulation process
