Vertical Upflow Convective Boiling: Flow Regimes, Heat Transfer and EHD Augmentation
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2018)This work focuses on vertical upflow convective boiling in a tubular heat exchanger. The work is experimental and utilizes a novel transparent sapphire test section coated with a transparent film of ITO. This allows ... -
Very large fMRI study using the IMAGEN database: sensitivity - specificity and population effect modelling in relation to the underlying anatomy
(2012)In this paper we investigate the use of classical fMRI Random Effect (RFX) group statistics when analysing a very large cohort and the possible improvement brought from anatomical information. Using 1326 subjects from the ... -
Vibration control of offshore wind turbines using tuned liquid column dampers
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2008) -
Vibration control of spar-type floating offshore wind turbine towers using a tuned mass-damper-inerter
(2019)This paper investigates the use of a passive tuned mass‐damper‐inerter (TMDI) for vibration control of spar‐type floating offshore wind turbine towers. The TMDI is a relatively new concept as a passive vibration control ... -
Vibration control of structures using active and semi-active tuned mass dampers
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2006)This study addresses the vibration control of tall and flexible structures, such as wind turbine towers (WTTs). Investigations into the use of single and multiple tuned mass dampers (TMDs) with passive, active and semi-active ... -
Vibration control of wind turbines with variable rotor sped and grid faults
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2014)The aim of this thesis is to propose, design and analyze vibration mitigation systems in wind turbines. Formulations have been developed to include variations of the rotational speed of the blades. The control methodologies ... -
Vibration Control of Wind Turbines: Recent Advances and Emerging Trends
(2020)The wind energy sector globally is expanding and developing technically at a rapid pace. Demand for renewable energy is soaring and there is a need for increasing the efficiency and design life of wind turbine ... -
Video Matting Using Motion Extended GrabCut.
(IEEE, 2008)GrabCut is perhaps the most powerful semi-automatic algorithm for matting presented to date. In its existing form, it is not suitable for video object segmentation. This paper considers major extensions that make it ... -
Video object segmentation from long term trajectories
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2011) -
Virtual Historic Centers: Digital Representation of Archaeological Heritage
(Springer Nature, 2022)Digitization and virtual representation of archaeology and architectural heritage potentially connects tangible and intangible cultural assets allowing for recording, conserving, and documenting cultural heritage. Process ... -
Virtual Radios, Real Services: Enabling End-to-End Network Slicing through Radio Virtualisation
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2021)This work aims to resolve some resource management problems that arise due to changes in the mobile network market and business models, brought by recent trends in commercial mobile networks, such as the widening range of ... -
Viscoelastic properties of passive skeletal muscle in compression: cyclic behaviour
(2009)The compressive properties of skeletal muscle are important in impact biomechanics, rehabilitation engineering and surgical simulation. However, the mechanical behaviour of muscle tissue in compression remains poorly ... -
ViSQOL: an objective speech quality model
(2015)This paper presents an objective speech quality model, ViSQOL, the Virtual Speech Quality Objective Listener. It is a signal-based, full-reference, intrusive metric that models human speech quality perception using a ... -
ViSQOL: The Virtual Speech Quality Objective Listener
(2012)A model of human speech quality perception has been developed to provide an objective measure for predicting subjective quality assessments. The Virtual Speech Quality Objective Listener (ViSQOL) model is a signal based ... -
ViSQOLAudio: An objective audio quality metric for low bitrate codecs
(2015)Streaming services seek to optimise their use of bandwidthacross audio and visual channels to maximise the quality of experiencefor users. This letter evaluates whether objective quality metrics can pre-dict the audio ... -
A Viterbi tracker for local features
(SPIE, 2010)The long term tracking of sparse local features in an image is important for many applications including camera calibration for stereo applications, camera or global motion estimation and people surveillance. The majority ... -
Volume effects in glued laminated timber beams
(2023)This paper discusses several aspects related to volume effects on glued laminated timber (GLT) beams, with focus on the combined effects of height and length on the bending strength. Challenges related to the prediction ... -
Vortex shedding from a wind turbine blade section at high angles of attack
(2013)The unsteady flow around a stationary two-dimensional wind turbine blade section (NREL S809) has been simulated using unsteady RANS with the SST turbulence model at Re = 106 and high angles of attack. Vortex shedding ...
