An investigation into time pressure, group cohesion and decision making in software development groups
(Australasia Conference on Information Systems (ACIS), 2014-12-04)Two of the key themes in contemporary ISD literature are (i) how to build and release systems in shorter time frames and (ii) how to enable work group to build systems in a cohesive manner. This is reflected by today s ... -
Analysis of in vivo skin anisotropy using elastic wave measurements and Bayesian modelling
(Springer, 2023-04-06)In vivo skin exhibits viscoelastic, hyper-elastic and non-linear characteristics. It is under a constant state of non-equibiaxial tension in its natural configuration and is reinforced with oriented collagen fibers, which ... -
Voltage-controlled topological interface states for bending waves in soft dielectric phononic crystal plates
(Elsevier, 2022-11-19)The operating frequency range of passive topological phononic crystals is generally fixed and narrow, limiting their practical applications. To overcome this difficulty, here we design and investigate a one-dimensional ... -
Non-destructive mapping of stress and strain in soft thin films through sound waves
(Nature Research, 2022-09-17)Measuring the in-plane mechanical stress in a taut membrane is challenging, especially if its material parameters are unknown or altered by the stress. Yet being able to measure the stress is of fundamental interest to ... -
Stochastic modelling of pesticide transport to drinking water sources via runoff and resulting human health risk assessment
(Elsevier, 2024-02-09)A modelling framework was developed to facilitate a probabilistic assessment of health risks posed by pesticide exposure via drinking water due to runoff, with the inclusion of influential site conditions and in-stream ... -
Representing the stress and strain energy of elastic solids with initial stress and transverse texture anisotropy.
(The Royal Society, 2022-10-12)Real-world solids, such as rocks, soft tissues and engineering materials, are often under some form of stress. Most real materials are also, to some degree, anisotropic due to their microstructure, a characteristic often ... -
Modelling brain tissue elasticity with the Ogden model and an alternative family of constitutive models.
(The Royal Society, 2022-08-29)The Ogden model is often considered as a standard model in the literature for application to the deformation of brain tissue. Here, we show that, in some of those applications, the use of the Ogden model leads to the ... -
The Ogden model of rubber mechanics: 50 years of impact on nonlinear elasticity
(The Royal Society, 2022-08-29)We place the Ogden model of rubber elasticity, published in Proceedings of the Royal Society 50 years ago, in the wider context of the theory of nonlinear elasticity. We then follow with a short interview of Ray Ogden FRS ... -
Nonlinear vibration and stability of a dielectric elastomer balloon based on a strain-stiffening model
(Springer, 2022-05-23)Limiting chain extensibility is a characteristic that plays a vital role in the stretching of highly elastic materials. The Gent model has been widely used to capture this behaviour, as it performs very well in fitting ... -
Plane-polarised finite-amplitude shear waves in deformed incompressible materials
(SAGE Publications, 2022-04-07)We investigate how two finite-amplitude, transverse, plane body waves may be superposed to propagate in a deformed hyperelastic incompressible solid. We find that the equations of motion reduce to a well-determined system ... -
The generalised Mooney space for modelling the response of rubber-like materials
(Springer, 2022-03-23)Soft materials such as rubbers, silicones, gels and biological tissues have a nonlinear response to large deformations, a phenomenon which in principle can be captured by hyperelastic models. The suitability of a candidate ... -
A hyperbolic framework for shear sound beams in nonlinear solids
(Elsevier, 2021-09-14)In soft elastic solids, directional shear waves are in general governed by coupled nonlinear KZK-type equations for the two transverse velocity components, when both quadratic nonlinearity and cubic nonlinearity are taken ... -
Acousto-elasticity of transversely isotropic incompressible soft tissues: Characterization of skeletal striated muscle
(IOP Publishing, 2021-07-13)Using shear wave elastography, we measure the changes in the wave speed with the stress produced by a striated muscle during isometric voluntary contraction. To isolate the behaviour of an individual muscle from complementary ... -
Full torso and limited-domain computer models for epicardial pulsed electric field ablation
(Elsevier, 2022-05-18)Background and objectives Pulsed Electric Field (PEF) ablation has been proposed as a non-thermal energy to treat atrial fibrillation (AF) by ablation of ganglionated plexi using the epicardial approach. The electric field ... -
In silico modelling to assess the electrical and thermal disturbance provoked by a metal intracoronary stent during epicardial pulsed electric field ablation
(MDPI, 2022-12-14)Background: Pulsed Electric Field (PEF) ablation has been recently proposed to ablate cardiac ganglionic plexi (GP) aimed to treat atrial fibrillation. The effect of metal intracoronary stents in the vicinity of the ablation ... -
Methodology and position paper for a review study on the conceptualisation and delivery of family support in Europe
(EurofamNet, 2019)The European Family Support Network (EurofamNet https://eurofamnet.eu/home) is a panEuropean network promoting collaboration between researchers, practitioners, policy agencies and service user organisations. Its aims to ... -
Pulsed electric field ablation of epicardial autonomic ganglia: Computer analysis of monopolar electric field across the tissues involved
(MDPI, 2022-11-27)Background and objectives: Pulsed Electric Field (PEF) ablation has been proposed as a non-thermal energy to treat atrial fibrillation (AF) by epicardial ablation of ganglionated plexi (GP), which are embedded within ... -
