Cryptography using evolutionary computing
(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
(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
(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 ...
Active and collaborative learning items on the Irish Survey of Student Engagement (ISSE); Interpretations of, and responses to by students and staff of the Department of Science at LYIT
(2016-08-31)
This study focusses specifically on questions on collaborative learning within the area of ‘Active learning’ in the Irish Survey of Student Engagement (ISSE) which was piloted in Ireland in 2013 and was rolled out in full ...
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 ...
Access/Preparatory Studies Programmes at LYIT – Students’ Perspectives
(2016-08)
There is little available research about the opinions and experiences of students who undertake Access/Preparatory Studies programmes in Ireland. This is an exploratory project which attempts to address this lack of ...
Biological control of pyrenophora teres
(2005)
Pyrenophora teres the causal organism of barley net blotch disease is responsible for
substantial loss in crop yield with yield losses as high as 40% under favourable
conditions. Current control measures are achieved ...
Error-free authentication watermarking based on prediction-error-expansion reversible technique
(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
(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
(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 ...
