An Experimental and Modelling Study of the Oxidation of n-Propylbenzene Over a Wide Range of Temperatures and Pressures and its Comparison with n-Butylbenzene
(2013-04-05)This study presents an experimental and modeling investigation of the ignition of n-propylbenzene and a mixture of n-propylbenzene and n-heptane. This mixture was chosen to represent a surrogate for n-decylbenzene a common ... -
Experimental and numerical assessment of MRI-induced temperature change and SAR distributions in phantoms
(Springer Verlag, 2017-06)During an MR procedure, most of the transmitted RF power is transformed into heat within the patient’s tissue and implants as a result of resistive losses which is referred to as the specific energy absorption rate (SAR) ... -
Experimental and numerical characterisation of materials for biomass co-firing
(2017-02-23)As Europe continues to decarbonize its electricity generation capacity, operators of thermal power plants face challenges to which they must adapt including increasingly transient operation and co-firing with biomass. This ... -
Experimental and numerical characterisation of the cyclic thermo-mechanical behaviour of a high temperature forming tool alloy
(American Society of Mechanical Engineers, 2010-10-05)This paper describes high temperature cyclic and creep relaxation testing and modeling of a high nickel-chromium material (XN40F) for application to the life prediction of superplastic forming (SPF) tools. An experimental ... -
Experimental and numerical characterisation of the elasto-plastic properties of bovine trabecular bone and a trabecular bone analogue
(2012)The inelastic pressure dependent compressive behaviour of bovine trabecular bone is investigated through experimental and computational analysis. Two loading configurations are implemented, uniaxial and confined compression, ... -
An experimental and numerical study of moisture flow and moisture-induced strain in fast-grown Sitka spruce
(Departamento de Ingeniería en Maderas de la Universidad del Bio-Bio en Concepción, Chile, 2019)The use of fast-grown timber in the manufacture of engineered wood products is increasing; however, the fast growth rate results in a low-density timber that is susceptible to significant swelling and shrinkage deformations ... -
Experimental Assessment of an Emotion Tracking Software Agent (ETA) for Assisting Communicative Interactions of Multitasking Users in Groupware
(Eurosis, 2011-08-22)Interactions such as discussion and negotiation in face-to-face work contexts strongly rely on non-verbal feedback. Such feedback provides indications of important negotiation states such as agreement or disagreement and ... -
Experimental assessment of clinical MRI-induced global SAR distributions in head phantoms
(Elsevier, 2019-10-05)Accurate estimation of SAR is critical to safeguarding vulnerable patients who require an MRI procedure. The increased static field strength and RF duty cycle capabilities in modern MRI scanners mean that systems can easily ... -
Experimental assessment of MRI-induced temperature change and SAR distributions in phantoms
(NUI Galway, 2017-11-14)During an MR procedure, most of the transmitted RF power is transformed into heat within the patients’ tissue resulting from resistive losses, referred to as the specific energy absorption rate(SAR) (2). The EU standardisation ... -
Experimental characterisation and computational constitutive modelling of high temperature degradation in 9Cr steels including microstructural effects
(2016-04-20)The transition from base-load to intermittent power plant operation has led to the requirement for increased knowledge and more accurate prediction of the effects of flexible loading on plant components. This thesis is ... -
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 ... -
Experimental characterisation of neural tissue at collision speeds
(International Research Council on Biomechanics of Injury (IRCOBI), 2012)Mechanical characterisation of brain tissue at high loading velocities is particularly important for modelling Traumatic Brain Injury (TBI). During severe impact conditions, brain tissue experiences a mixture of compression, ... -
Experimental characterisation of the moment-rotation behaviour of beam-beam connections using compressed wood fasteners
(Elsevier, 2021-09-16)The widespread use of energy-intensive metallic connectors and synthetic adhesives in modern timber construction has negative implications for the end-of-life disposal or re-use of the structural timber components. Therefore, ... -
Experimental characterisation, computational modelling and design tool development for fretting fatigue and wear in flexible marine risers
(2017-09-25)Fretting is a key concern in the fatigue design of the pressure armour layer of flexible marine risers, due to the combination of extreme global dynamic loading conditions and the local geometrical-tribological conditions ... -
Experimental characterization and strengthening mechanism of process-structure-property of selective laser melted 316 L
(Elsevier, 2023-03-02)Heat treatment is the most common method to relieve residual stress and to adjust tensile properties in additively manufactured material. However, the well-known strengthening factors (e.g., dislocation density, cellular ... -
Experimental development and modelling of a novel auxiliary power unit for heavy trucks
(2017-09-26)This thesis identifies the key technical requirements for a heavy truck auxiliary power unit (APU) and explores a potential alternative technology for use in a next-generation APU that could eliminate key problems related ... -
Experimental evaluation of the effective ablation zone on ex-vivo bovine liver samples
