(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2013)The work presented in this thesis is an investigation into the variables that are considered by consumers when selecting low carbon technologies (LCT) and the barriers that are encountered by implementers when deploying ... -
Active strategies with TMDs for control of wind turbine vibrations
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2012)This thesis investigates the use of active structural control techniques for the mitigation of the dynamic response of wind turbines with particular emphasis on reducing the in-plane (edgewise) vibrations in wind turbine ... -
An 'Urban Spacebook' : re-mapping the city with mobility practices and experiences
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2014)This thesis argues that urban sustainability cannot be reached without city inhabitants becoming more connected and engaged with their city and participating (inter)actively in planning their environments. It acknowledges ... -
An analysis of cycling safety perceptions and development of a bicycle trip assignment methodology
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2015)This thesis reports the outcome of research on the development of an alternative method to modelling the assignment of bicycle trips in multi-modal networks. The proposed methodology considers the effects of safety (or ... -
An assessment of the performance of willow evapotranspiration systems for the treatment of on-site wastewater in Ireland
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2014)In Ireland, domestic wastewater from approximately 400,000 dwellings is treated by on-site systems which are all designed to distribute the treated effluent to groundwater via the subsoil on the site. Low permeability ... -
An experimental study of the physical properties of lime mortar and their effect on lime-mortar masonary
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2013)The objective of this research is to provide new data in respect to the mechanical behaviour of lime mortar and masonry traditionally used in Ireland, especially the effect of water content and curing time and curing ... -
An investigation into the optimisation of a solar photocatalytic continuous flow disinfection system
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2010)Solar photocatalytic disinfection is thought to be a safe, effective, low-cost method of drinking water treatment and would be applicable, for example, to village-scale systems in developing countries. In this thesis, an ... -
