When these ... -
Investigating cortical encoding of auditory space & motion in humans using EEG
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2020)This work uses a novel linear regression-based framework together with scalp recorded electroencephalography (EEG) to study various aspects of spatial hearing in humans. In our first study, we showed that in an acoustic ... -
Investigating the Neural Correlates of Speech Processing & Selective Auditory Attention using EEG
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2020)Speech comprehension is a remarkable human ability. Most normal-hearing people are adept at attending to a speech stream even amidst a noisy multi-talker background and parsing the layers of information it contains in ... -
observation of an anomalous SmA-SmC-SmA phase sequence in a bent-core liquid crystal derived from 4-cyanoresorcinol
(2020)The physical properties and the phase transitions of a smectic liquid crystal material built from achiral bent-core molecules are investigated by electro-optics, polarizing microscopy, birefringence, and spontaneous ... -
Designing for the Future: A Complex Systems Approach to Communication Networks
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2020)The network size and the deployment density of wireless networks continue to increase from year to year. Additionally, networks are experiencing an operational shift that affects both: (1) the network architecture, and (2) ... -
Formation and development of nanometer-sized cybotactic clusters in bent-core nematic liquid crystalline compounds
(2018)Two homologue achiral bent-core liquid crystals (LCs), BCN66 and BCN84, in their nematic phases are studied by dielectric spectroscopy in the frequency range 10 Hz–10 MHz. In each of these compounds, two relaxation processes ... -
