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) ...
IEEE 802.15.4a UWB-IR ranging with bilateral transmitter power control methodology for multipath effects mitigation
(Signals and Systems Conference (ISSC 2013), 24th IET Irish, 2013-06)
IEEE 802.15.4a Ultra Wideband Impulse Radio (UWB-IR) measures the distance using the time-of-arrival (TOA) of the leading path signal. Multipath propagation in indoor environments can adversely affect the signal to noise ...
Impact of DFT properties on the inherent resolution of compressed sensing reconstructed images
(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 ...
Prototype test insertion co-processor for agile development in multi-threaded embedded environments
(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 ...
Ghostbusters: A parts-based NMF algorithm
(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 ...
Extraction of reliability indicators from large-scale, highly variable timing data of MEMS switches
(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 ...
Phase noise analysis of Colpitts and Hartley CMOS oscillators
(Signals and Systems Conference (ISSC 2013), 24th IET Irish, 2013-06)
This paper reports comparative analyses of the phase noise predictions through Cadence simulations for two LC oscillator topologies: Colpitts and Hartley oscillators. The oscillators have been designed and phase noise ...
Comparing and contrasting smartphone and non-smartphone usage
(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 ...
Wireless sensed environment for body area networks
(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 ...
Robust digital video watermarking using reversible data hiding and visual cryptography
(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 ...
