Dynamic Ordering of Firewall Rules Using a Novel Swapping Window-based Paradigm
(Peer reviewed; Chapter, 2016)Designing and implementing efficient firewall strategies in the age of the Internet of Things (IoT) is far from trivial. This is because, as time proceeds, an increasing number of devices will be connected, accessed and ... -
The Dynamical Landscape of Reservoir Computing with Elementary Cellular Automata
(Conference object, 2021)Reservoir Computing with Cellular Automata (ReCA) is a promising concept by virtue of its potential for efficient hardware implementation and theoretical understanding of Cellular Auotmata (CA). However, ReCA has so far ... -
Early functional changes associated with alpha-synuclein proteinopathy in engineered human neural networks
(American Journal of Physiology - Cell Physiology;, Peer reviewed; Journal article, 2021-06-18)A patterned spread of proteinopathy represents a common characteristic of many neurodegenerative diseases. In Parkinson’s disease (PD), misfolded forms of alpha-synuclein proteins accumulate in hallmark pathological ... -
Early Labour App: Developing a practice-based mobile health application for digital early labour support
(Peer reviewed; Journal article, 2023)Background: Pregnant women in early labour have felt excluded from professional care, and their partners have been restricted from being involved in the birthing process. Expectant parents must be better prepared to deal ... -
Edge information based image fusion metrics using fractional order differentiation and sigmoidal functions
(IEEE Access;Volume: 8, Journal article; Peer reviewed, 2020)In recent years, the number of image fusion schemes presented by the research community has increased significantly. Measuring the performance of these schemes is an important issue. In this work, we introduce three ... -
EEG-based affect classification with machine learning algorithms
(Chapter, 2023)In this paper, we aim to study the EEG-based emotion recognition problem. First, we use clustering algorithm to determine the target class of emotions and perform binary classification of emotion along its arousal and ... -
