Comparing how entrepreneurs and managers represent the elements of the business model canvas
(Elsevier, 2018-03-03)This paper uses self-efficacy to compare how entrepreneurs and managers represent the nine elements of the business model canvas (BMC; Osterwalder, 2004). A six-item efficacy scale was developed to measure each element. ... -
Comparison of high temperature chars of wheat straw and rice husk with respect to chemistry, morphology and reactivity
(Elsevier, 2016-03-02)Fast pyrolysis of wheat straw and rice husk was carried out in an entrained flow reactor at high-temperatures (1000–1500) °C. The collected char was analyzed using X-ray diffractometry, N2-adsorption, scanning electron ... -
A comparison of two quasi-static computational models for assessment of intra-myocardial injection as a therapeutic strategy for heart failure
(Wiley, 2019-05-06)Myocardial infarction, or heart attack, is the leading cause of mortality globally. Although the treatment of myocardial infarct has improved significantly, scar tissue that persists can often lead to increased stress and ... -
Computational modelling of dynamic recrystallisation of Ni-based superalloy during linear friction welding
(Springer, 2022-01-12)Linear friction welding (LFW) is an advanced joining technology used for manufacturing and repairing complex assemblies like blade integrated disks (blisks) of aeroengines. This paper presents an integrated multiphysics ... -
Computational simulation of the relaxation of local stresses due to foreign object damage under cyclic loading
(2010)In this study, the phenomenon of residual stress relaxation from foreign object damage (FOD) is numerically simulated using a hybrid explicit¿implicit finite-element method. The effects of cycle fatigue loadings on stress ... -
Computational study on the effect of contact geometry on fretting behaviour
(Elsevier ScienceDirect, 2011-07-23)A key challenge in the design of engineering couplings and contacting components relates to the development of an understanding of the comparative performance of contrasting contact geometries for a given application, ... -
Cosmic sounds: A game to support phonological awareness skills for children with dyslexia
(2022)Studies show that reduced literacy skills can negatively influence a child¿s self-esteem and future career opportunities. Literacy is significantly affected when problems exist understanding the phonological component or ... -
A critical analysis of plastic flow behaviour in axisymmetric isothermal and Gleeble compression testing
(Elsevier ScienceDirect, 2010-08-16)Coupled thermo-mechanical finite element modelling of both isothermal axisymmetric compression and compression testing using the Gleeble thermo-mechanical simulator has been carried out in order to compare the levels of ... -
Cyclic plasticity of welded P91 material for simple and complex power plant connections
(Elsevier, 2016-02-10)This paper focuses on with the cyclic plasticity modelling of welded, ex-service P91 material. A multi material model is developed for high temperature cyclic plasticity, including the effects of the three different material ... -
Cyclic thermo-mechanical material modelling and testing of 316 stainless steel
(Elsevier ScienceDirect, 2010-04-20)A programme of cyclic mechanical testing of a 316 stainless steel, at temperatures of up to 600 C under isothermal conditions, for the identification of material constitutive constants, has been carried out using a ... -
Cyclic viscoplasticity testing and modelling of a service-aged P91 steel
(American Society of Mechanical Engineers, 2014-04-16)A service-aged P91 steel was used to perform an experimental program of cyclic mechanical testing in the temperature range of 400 °C–600 °C, under isothermal conditions, using both saw-tooth and dwell (inclusion of a ... -
Damage characterisation of cryogenically cycled carbon fibre/PEEK laminates
(Elsevier ScienceDirect, 2014-08-14)A unique insight into damage formation in CF/PEEK laminates before, during and after cryogenic cycling, using optical microscopy and 3D X-ray computed tomography (CT), is presented. Thicker laminates were found to exhibit ... -
Defect evaluation of the honeycomb structures formed during the drilling process
