Vortex shedding lock-in due to pitching oscillation of a wind turbine blade section at high angles of attack
(2019)The unsteady flow around a pitching two-dimensional airfoil section (NREL S809) has been simulated using unsteady RANS with the transition SST turbulence model. This geometry is chosen to represent a wind turbine blade in ... -
Vortex shedding lock-in of a 2-D wind turbine blade section at high angles of attack
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2015)The vortex shedding behaviour of a 2-D wind turbine blade section at high angles of attack (a = [35° —>145°]) has been investigated using unsteady RANS with the transition SST turbulence model. The Reynolds number is Re = ... -
Vowel Formant Profiles and Image Schemata and Auditory Display
(2018)This paper presents two evaluations intended to examine if listeners are more likely to associate certain vowel formant profiles with specific data types in an auditory display context. The data types and sounds chosen ... -
Vulnerabilities in Water Distribution Systems Using N-k Contingency Analysis
(2023)Adequate performance of water distribution systems is at the core of community resilience. Water distribution systems are vulnerable to a variety of hazards, as they are susceptible to direct physical damage (e.g., ... -
Vulnerability Assessment of Infrastructure Networks Following Earthquakes: The Fundamental Step to Assess Network Resilience and Functional Recovery
(2023)Disruptive events can result in devastating damage and interruptions in distributed infrastructure networks (e.g., Transportation network), affecting the lives and wellbeing of communities that rely on their functionality. ... -
Wastewater as a thermal resource: Exploitation strategies, design methodologies & prototype development
(Trinity College Dublin. School of Engineering. Disc of Civil Structural & Environmental Eng, 2020)The disruption of the climate was identified as one of nine planetary boundaries, and is one for which we are reaching the limits of safe operation on this planet. To that effect the European Commission launched the European ... -
Water content determinations for peat and other organic soils using the oven-drying method
(2014)There has been much debate in literature over the past 60 years regarding an appropriate oven-drying temperature for water content determinations on peat and other organic soils. For inorganic soils, the water content is ... -
Water droplet evaporation in varied gravity and electric fields
(2024)Sessile water droplet evaporation in varied gravity and electric fields has been experimentally studied. Specifically, the influences of gravity and electric fields are investigated in the context of the heat flux distribution ... -
Watermarking digital images for copyright protection
(IEE, 1996)A watermark is an invisible mark placed on an image that is designed to identify both the source of an image as well as its intended recipient. The authors present an overview of watermarking techniques and demonstrate a ... -
Watermarking digital images for copyright protection
(IEE, 1995)A watermark is all invisible mark placed on an image that can only be detected when the image is compared with the original. This mark is designed to identify both the source of a document as well as its intended recipient. ... -
Wavelet‐based individual blade pitch control for vibration control of wind turbine blades
(2019)This paper proposes a novel individual blade pitch control strategy with the objective of reducing blade vibration. A wavelet linear quadratic regulator (LQR) control algorithm, which is an advanced modification of the ... -
A wavelet-based Bayesian framework for 3D object segmentation in microscopy
(2012)In confocal microscopy, target objects are labeled with fluorescent markers in the living specimen, and usually appear with irregular brightness in the observed images. Also, due to the existence of out-of-focus objects ... -

Wavelet-Bayesian hierarchical stochastic model for short-term traffic flow at noncritical junctions
(2008)In ITS (Intelligent Transportation System) equipped urban transportation systems noncritical junctions are often ignored in short-term traffic condition prediction algorithms as the traffic data collection systems in ... -
Wear of grinding wheels - software for their selection
(2004)An existing model of the grinding process has been upgraded to predict grinding wheel wear as G ratios. It has been successfully benchmarked against experimental results for several combinations of coolant wheel and ... -
Weathering and consolidation trials on sandstones used in Irish Monuments.
(LNEC, Laboratorio Nacional de Engenharia Civil, Lisbon, 2008)The objective of this study was to assess the efficiency of consolidant treatments in improving the durability of Irish sandstones, particularly sandstones used in national monuments at Cashel, Clonfert and Clonmacnoise. ... -
What causes energy and transport poverty in Ireland? Analysing demographic, economic, and social dynamics and policy implications
(2022)Energy and transport poverty have been postulated as conditions linked by overlapping causal factors such as structural economic inequality or housing stock and affecting overlapping demographics such as family size or ...
