Comparison of three buck topologies for wide output voltage applications
Anderson, Oisín; Barry, Brendan; Hogan, Diarmuid; Duffy, Maeve (IEEE, 2023-05-31)This paper investigates the suitability of three step-down dc-dc converter topologies as the final conversion stage in a wide output voltage modular ac-dc power supply. Single-phase, two-phase and three-level buck converters ... -
Computational modelling of the coupled electro-mechanical behaviour of neurons
Cinelli, Ilaria (NUI Galway, 2019-01-22)Recent experimental evidence has uncovered complex biophysical phenomena accompanying the electrical activity of nervous cells. Now emerging theories refer to the electric pulse, i.e. the Action Potential (AP), as an ... -
Effects of nerve bundle geometry on neurotrauma evaluation
Cinelli, Ilaria; Destrade, Michel; McHugh, Peter; Duffy, Maeve (Wiley, 2018-06-16)ObjectiveWe confirm that alteration of a neuron structure can induce abnormalities in signal propagation for nervous systems, as observed in brain damage. Here, we investigate the effects of geometrical changes and damage ... -
Electro-mechanical response of a 3D nerve bundle model to mechanical loads leading to axonal injury
Cinelli, Ilaria; Destrade, Michel; Duffy, Maeve; McHugh, Peter (Wiley, 2017-11-21)Traumatic brain injuries and damage are major causes of death and disability. We propose a 3D fully coupled electro-mechanical model of a nerve bundle to investigate the electrophysiological impairments due to trauma at ... -
Electrothermal equivalent three-dimensional finite-element model of a single neuron
Cinelli, Ilaria; Destrade, Michel; Duffy, Maeve; McHugh, Peter (Institute of Electrical and Electronics Engineers, 2017-09-14)Objective: We propose a novel approach for modelling the interdependence of electrical and mechanical phenomena in nervous cells, by using electrothermal equivalences in finite element (FE) analysis so that existing ... -
Enhancing the situational awareness of the active distribution network
Khan, Maman Ahmad (NUI Galway, 2022-06-21)Power distribution system operation has become increasingly complex with the large-scale integration of Distributed Energy Resources (DERs). This has led to a paradigm shift in the operation and planning of the power ... -
Head-to-nerve analysis of electromechanical impairments of diffuse axonal injury
Cinelli, Ilaria; Destrade, Michel; McHugh, Peter; Trotta, Antonia; Gilchrist, Michael; Duffy, Maeve (Springer, 2018-11-14)The aim was to investigate mechanical and functional failure of diffuse axonal injury (DAI) in nerve bundles following frontal head impacts, by finite element simulations. Anatomical changes following traumatic brain injury ... -
