Cunningham, H. J. (author), Higgins, C. (author), van den Bremer, T.S. (author)Recently, a number of authors have used global particle tracking simulations to identify the effect that different surface currents have on marine litter accumulation, including the role of surface waves through the Stokes drift. However, in the upper-ocean boundary layer and in the presence of the Coriolis force, a wave-driven Eulerian flow...journal article 2022

Mokhtar, Maizura (author), Robu, Valentin (author), Flynn, David (author), Higgins, Ciaran (author), Whyte, Jim (author), Loughran, Caroline (author), Fulton, Fiona (author)The energy landscape for the Low-Voltage (LV) networks is undergoing rapid changes. These changes are driven by the increased penetration of distributed Low Carbon Technologies, both on the generation side (i.e. adoption of micro-renewables) and demand side (i.e. electric vehicle charging). The previously passive ‘fit-and-forget’ approach to...journal article 2021

(author), Savenije, Hubert (author), van de Giesen, N.C. (author)Near-surface wind speed is typically only measured by point observations. The actively heated fiber-optic (AHFO) technique, however, has the potential to provide high-resolution distributed observations of wind speeds, allowing for better spatial characterization of fine-scale processes. Before AHFO can be widely used, its performance needs...journal article 2020

Frößler, Frank (author), Rukanova, B.D. (author), Klein, Stefan (author), Higgins, A. (author), Tan, Y. (author), Kelly, S (author)The Beer Living Lab was the first of a series of living labs established to analyse and improve complex cross-border trade and logistics challenges using innovative information technology. Unlike stable inter-firm networks where roles are formal and explicit, role taking and role assigning in the Beer Living Lab was highly dynamic. Although...book chapter 2018

(author)The presence in space of micrometeoroids and orbital debris, particularly in the lower earth orbit, presents a continuous hazard to orbiting satellites, spacecrafts and the international space station. Space debris includes all non-functional, man-made objects and fragments. As the population of debris continues to grow, the probability of...conference paper 2013

(author)A frequency tunable terahertz heterodyne spectrometer, based on a third-order distributed feedback quantum cascade laser as a local oscillator, has been demonstrated by measuring molecular spectral lines of methanol (CH3OH) gas at 3.5 THz. By varying the bias voltage of the laser, we achieved a tuning range of ? 1?GHz of the lasing frequency,...journal article 2011

(author), Kumar, S. (author), Hu, Q. (author), Reno, J.L. (author)A terahertz (THz) heterodyne spectrometer is demonstrated based on a quantum cascade laser (QCL) as a local oscillator (LO) and an NbN hot electron bolometer as a mixer, and it is used to measure high-resolution molecular spectral lines of methanol (CH3OH) between 2.913–2.918 THz. The spectral lines are taken from a gas cell containing methanol...journal article 2010
