Individual blade pitch control strategies for spar-type floating offshore wind turbines
(Trinity College Dublin. School of Engineering. Disc of Civil Structural & Environmental Eng, 2020)The aim of this thesis is to study the dynamics of spar-type Floating Offshore Wind Turbines (FOWTs) and investigate the performance of the individual blade pitch control strategies proposed to improve dynamic response of ... -
Indoor/outdoor air quality relationship in urban commercial buildings
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2013)The United Nations urban environmental unit associates up to 1 million premature deaths annually to urban air pollution (United Nations Environment Programme, 2010). Much research on indoor environments has focused on ... -
Influence on spatial variability on whole life management of reinforced concrete bridges
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2009)The number of deteriorating bridges due to chloride-induced corrosion increases annually as does the cost of inspection, maintenance, repair and where necessary replacement. Meanwhile, budgets made available to bridge ... -
Infrared imaging analysis of hand skin temperature for thermal comfort assessment
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2015)Thermal comfort is a subjective sensation of the mind and body which expresses a level of satisfaction with the thermal environment. For years thermal comfort has been studied and external variables such as air temperature ... -
