Fatigue life of pitch- and stall-regulated composite tidal turbine blades
(Elsevier, 2018-02-28)
Tidal turbine blades are subject to harsh loading and environmental conditions, including large thrust and torsional loadings, relative to wind turbine blades, due to the high density of seawater, among other factors. The ...
Detecting the end of nitrification in small and decentralized wastewater treatment systems using low-resource real-time control methods
(American Society of Civil Engineers, 2018-06-12)
There is increasing demand on operators of small-scale wastewater treatment plants (WWTPs) to improve biological nutrient removal and energy efficiency while being subject to unique challenges, including reduced resources. ...
Experimental characterisation and computational modelling for cyclic elastic-plastic constitutive behaviour and fatigue damage of X100Q for steel catenary risers
(Elsevier, 2018-06-21)
New higher strength steels are required for deep and ultra-deepwater steel catenary risers (SCRs). In this work, the cyclic elastic-plastic-damage behaviour of X100Q, a candidate next-generation SCR material is experimentally ...
An experimental study of a flow-accelerating hydrokinetic device
(SAGE Publications, 2018-05-01)
Tidal energy researchers and developers use experimental testing of scaled devices as a method of evaluating device performance. Much of the focus to date has been on horizontal axis turbines. This study is focused on a ...
End use level water and energy interactions: A large non-residential building case study
(MDPI, 2018-06-19)
Within the European Union, buildings account for around 40% of the energy use and 36% of CO2 emissions, thus representing a significant challenge in the context of recent EU directives that require all new buildings to be ...
A physically-based high temperature yield strength model for 9Cr steels
(Elsevier, 2018-05-24)
The strength of 9Cr steels, which is controlled by chemical composition and microstructure, evolves significantly under high temperature loading. This paper presents a temperature-independent, physically-based model for ...
A model for surface tension in the meshless finite volume particle method without spurious velocity
(Elsevier, 2018-11-22)
A surface tension model has been developed in the finite volume particle method (FVPM). FVPM is a conservative, consistent, meshless particle method that incorporates properties of both smoothed particle hydrodynamics and ...
Effect of pre-corrosion on damage evolution and crack propagation in aluminum alloy 7050-T7651
(Wiley, 2018-05-16)
This paper investigates the effects of pre-corrosion on the tensile behavior of aluminum alloy 7050-T7651. A combined experimental approach involving digital image correlation, scanning electron microscopy, and tensile ...
The effect of ferrite phases on the micromechanical response and crack initiation in the intercritical heat-affected zone of a welded 9Cr martensitic steel
(Wiley, 2018-02-08)
This paper presents a crystal plasticity model to predict the tensile response and crack initiation in a mixed ferrite-martensite material with a low volume fraction of pro-eutectoid ferrite, representative of a welding-induced ...
Latent space mapping for generation of object elements with corresponding data annotation
(Elsevier, 2018-10-25)
Deep neural generative models such as Variational Auto-Encoders (VAE) and Generative Adversarial Networks (GAN) give promising results in estimating the data distribution across a range of machine learning fields of ...
