A two and three-dimensional CFD investigation into performance prediction and wake characterisation of a vertical axis turbine
(AIP Publishing, 2018-05-24)
The emergence of tidal energy as a key renewable energy source requires the development of computational design models for accurate prediction of turbine performance and wake effects whilst also being computationally ...
A precipitate evolution-based continuum damage mechanics model of creep behaviour in welded 9Cr steel at high temperature
(SAGE Publications, 2018-04-04)
A multiaxial, physically based, continuum damage mechanics methodology for creep of welded 9Cr steels is presented, incorporating a multiple precipitate-type state variable, which simulates the effects of strain- and ...
An anatomically accurate dielectric profile of the porcine kidney
(IOP Publishing, 2018-02-26)
Microwave ablation is a promising treatment for kidney cancer. Accurate knowledge of the dielectric properties of biological tissues is vital for quantifying the safety, reliability and accuracy of ablation, among other ...
Investigation of histology radius for dielectric characterisation of heterogeneous materials
(Institute of Electrical and Electronics Engineers, 2018-07-13)
Knowledge of the dielectric properties of biological tissues is fundamental in the design of novel electromagnetic-based medical devices. Tissue dielectric properties are typically measured using the open-ended coaxial ...
Modelling the sensing radius of a coaxial probe for dielectric characterisation of biological tissues
(Institute of Electrical and Electronics Engineers, 2018-08-22)
The open-ended coaxial probe is the most common measurement tool used to dielectrically characterize biological tissues. Most healthy and malignant biological tissues are macroscopically heterogeneous, with the exception ...
Image-based classification of bladder state using electrical impedance tomography
(IOP Publishing, 2018-12-03)
Objective: In this study, we examine the potential of using machine learning classification to determine the bladder state ( not full , full ) with electrical impedance tomography (EIT) images of the pelvic region. Accurate ...
Quantification of the sensing radius of a coaxial probe for accurate interpretation of heterogeneous tissue dielectric data
(Institute of Electrical and Electronics Engineers, 2018-05-31)
Accurate tissue dielectric measurements are crucial for the development of electromagnetic diagnostic and therapeutic devices that are designed based on estimates of the dielectric properties of diseased and healthy tissues. ...
The effect of inclusions on the high‐temperature low‐cycle fatigue performance of cast MarBN: Experimental characterisation and computational modelling
(Wiley, 2018-06-15)
The presence of inclusions is a known source of crack initiation and component failure in cast materials. In this work, the role of inclusions is investigated via a combined program of high-temperature low-cycle fatigue ...
Influence of microstructural defects and hydrostatic pressure on water absorption in composite materials for tidal energy
(SAGE Publications, 2018-01-06)
The lifespan and economic viability of tidal energy devices are constrained, in part, by the complex degradation of the tidal turbine blade materials due to prolonged immersion in a hostile sub-sea environment. Seawater ...
A through-process, thermomechanical model for predicting welding-induced microstructure evolution and post-weld high-temperature fatigue response
(Elsevier, 2018-02-11)
This paper is concerned with the development of a modelling framework to predict the effects of welding and post-weld heat treatment on thereto-mechanical performance of welded material, as a step towards a design tool for ...
