Nonlinear Damage Identification in Fiber-reinforced Cracked Composite Beams through Time-space Wavelet Analysis
(2014)It is well-known that wavelet analysis is, in the space domain, an efficient way to determinate the damage location (Pakrashi et al., 2007; Loutridis et al., 2004), while, in the time domain, it is an efficient tool to ... -
Nonlinear model predictive control to reduce pitch actuation of floating offshore wind turbines
(2020)Modern-day wind turbines use active pitch control to reduce mechanical loads on the turbines in addition to regulating generator power. These control algorithms increase blade pitch actuation, primarily to reduce the 1P ... -
Numerical modelling of the passive control of air pollution in asymmetrical urban street canyons using refined mesh discretization schemes
(2012)This study evaluates the potential of passive controls in asymmetrical street canyons to reduce personal exposure to air pollutants on footpaths. A passive control in the form of a low boundary wall (LBW) may act as a ... -
Nutrient loading on subsoils from on-site wastewater effluent, comparing septic tank and secondary treatment systems
(2009)The performance of six separate percolation areas was intensively monitored to ascertain the attenuation effects of unsaturated subsoils with respect to on-site wastewater effluent: three sites receiving septic tank effluent, ... -
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 ... -
Observer based pitch control for load mitigation and power regulation of floating offshore wind turbines
Most commercial wind turbines use proportional-integral (PI) collective blade- pitch control to regulate rotor speed in the above-rated wind speed regime. A significant drawback of this type of controller is that it ... -
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 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. ... -
Optimal transport pricing for Dublin

Optimising shared electric mobility hubs: Insights from performance analysis and factors influencing riding demand
(2023)In order to decarbonise the transport networks, systemic change is needed. One manifestation of this transformation is shared electric mobility, seeking to curtail car usage and ownership. This current case study aims to ...
