Exploring the origins of EEG motion artefacts during simultaneous fMRI acquisition: Implications for motion artefact correction
( Academic Press Inc. , 2018 , Article)Motion artefacts (MAs) are induced within EEG data collected simultaneously with fMRI when the subject's head rotates relative to the magnetic field. The effects of these artefacts have generally been ameliorated by removing ... -
Exposure assessment to WiFi access points by simulations and measurements
( IEEE , 2011 , Conference Paper)This paper discusses two different approaches to assess exposure to indoor WiFi access points at two different frequency bands: 2.4GHz and 5GHz. The first analyzes the electromagnetic propagation in almost empty environments ... -
Extended Kalman filter based sliding mode control of parallel-connected two five-phase PMSM drive system
( MDPI AG , 2018 , Article)This paper presents sliding mode control of sensor-less parallel-connected two five-phase permanent magnet synchronous machines (PMSMs) fed by a single five-leg inverter. For both machines, the rotor speeds and rotor ... -
Extended quantum cuts for unsupervised salient object extraction
( Springer New York LLC , 2017 , Article)In this manuscript, an unsupervised salient object extraction algorithm is proposed for RGB and RGB-Depth images. Saliency estimation is formulated as a foreground detection problem. To this end, Quantum-Cuts (QCUT), a ... -
Extracorporeal membrane oxygenation simulation-based training: methods, drawbacks and a novel solution
( SAGE Publications Ltd , 2019 , Article Review)Introduction: Patients under the error-prone and complication-burdened extracorporeal membrane oxygenation (ECMO) are looked after by a highly trained, multidisciplinary team. Simulation-based training (SBT) affords ECMO ... -
