An objective framework for determination of the air-entry value from the soil?water characteristic curve
(2021)The air-entry value (AEV) suction, marking the transition between saturated and unsaturated soil mechanics, is arguably the most important parameter interpreted from the soil–water characteristic curve (SWCC); its accurate ... -
Offshore wind-turbine structures: a review
(2013)This paper reviews various issues related to wind-power generation, one of the more popular forms of renewable energy, including attractions and challenges of electric power generation through onshore and offshore resources. ... -
On the calculation of offshore wind turbine load spectra for fatigue design
(2018)The present work researches on the definition of the load spectra used for offshore wind turbine low SN slope materials’ fatigue design. Uncertainty in the sample sized used to scale fatigue life is analyzed for the tower ... -
On the geotechnical design and use of peat bunds in the conservation of bogs
(Sfax, Tunisie, 2008) -
On the Modeling of Spar-type Floating Offshore Wind Turbines
(2013-07)In this paper an overview about floating offshore wind turbines (FOWT) including operating conditions, property and applicability of the barge, tension-leg, and spar floating platforms is described. The spar-floating ... -
On the similarity between discrete harmonic wavelet and discrete orthonormal S transform
(2023)Two efficient transforms: discrete harmonic wavelet transform (DHWT) and discrete orthonormal S transform (DOST) were developed in the literature. They can be used to analyze, model, and simulate nonstationary signals. ... -
On the suitability of the Generalised Pareto to model extreme waves
(2018)Dealing with extreme events implies working with events that have low probability of occurrence. To characterize these, the peak-over-threshold method alongside the generalized Pareto distribution is commonly applied. ... -
On the Value of Information forecasting with multi-information systems
(2023)The deterioration of structural components together with the climate and mobility increasing demands undermine civil structuresﾒ safety and functionality performance. Planning of maintenance activities is necessary, along ... -
On-line monitoring of ambient hydrocarbon concentrations
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2001)The result of a comprehensive set of hydrocarbon measurements undertaken at an urban roadside, rural and industrial site in Ireland are presented. Very little reported data on ambient hydrocarbon measurements were ... -
Online Aleatory Uncertainty Quantification for Probabilistic Time Series Models
(2023)Engineering problems rely on probabilistic models for decision making tasks. One such approach are the state-space models used for time series forecasting which involve unknown parameters for not only modelling physical ... -
Optimal Control Algorithms for Wave Energy Conversion
(Trinity College Dublin. School of Engineering. Disc of Civil Structural & Environmental Eng, 2022)The aim of this thesis is to design control strategies with the objective of power maximization for point absorber (PA) type of wave energy converter (WEC) devices, considering non-linearities and physical limitations ... -
Optimal exploitation of sparsely localised traffic data for modelling traffic flow in road networks
(2023)Traffic flow data are generally collected using induction loops. Therefore, to capture traffic dynamics along road sections, a very fine mesh of induction loops is required. However, due to their higher cost of installation ... -
Optimal mechanical performance prediction of a sediment-based geopolymer road sub-layer
(2023)One of the major obstacles for the implementation of dredged sediment in the manufacture of concrete is its variable mineralogical properties. However, its use in the manufacture of geopolymer binder as proven to be an ... -
Optimal Real-Time Predictive Control for Maximising the Power-Take-Off Efficiency of the WaveRAM Wave Energy Converter
(Trinity College Dublin. School of Engineering. Disc of Civil Structural & Environmental Eng, 2018)The aim of this thesis is to develop a control strategy for optimising the power-take-off (PTO) efficiency of the newly developed WaveRAM (WRAM) wave energy converter. The three main research streams established to satisfy ... -
Optimal risk-based design of a RC frame under column loss scenario
(2023)Structural systems may be subject to abnormal loads with small probability of occurrence but great intensity, which may lead to local damage, and even loss of loadbearing elements. In this context, it is important to design ... -
Optimal transport pricing for Dublin

Optimisation of inspection planning for structures
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2009)The main aim of this thesis was the development of a maintenance management methodology which incorporates two aspects of a structural inspection, i.e. (i) detection of a defect and (ii) sizing of a defect. Markov transition ...
