Scale-up of an unsteady flow field for enhanced spatial and temporal resolution of PIV measurements: application to leaflet wake flow in a mechanical heart valve
(Springer, 2011-07)A scale-up approach is developed to enhance effective spatial and temporal resolution of PIV measurements. An analysis shows that complete similarity can be maintained for certain unsteady flows and that all types of error ... -
A scorecard for supporting enterprise knowledge management
(2003)Enterprise knowledge management is becoming a critical component of competitive success. Managers must ensure that they can successfully generate, leverage and reuse knowledge assets in their organisations. In this view, ... -
Secondary comminution of wood pellets in power plant and laboratory-scale mills
(Elsevier, 2017-03-14)This study aims to determine the influence of mill type and pellet wood composition on particle size and shape of milled wood. The size and shape characteristics of pellets comminuted using power plant roller mills were ... -
Simulation of turbulent flow in a rapid compression machine: Large Eddy Simulation and computationally efficient alternatives for the design of ignition delay time experiments
(Elsevier, 2018-07-05)Rapid compression machines (RCMs) are widely used by the fuel research community to provide engine-relevant conditions to study ignition delay time (IDT), which is a crucial target for validating chemical kinetic mechanisms ... -
A strain-gradient, crystal plasticity model for microstructure-sensitive fretting crack initiation in ferritic-pearlitic steel for flexible marine risers
(Elsevier, 2018-02-03)A three-dimensional, strain-gradient, crystal plasticity methodology is presented for prediction of microstructure-sensitive length-scale effects in crack initiation, under fatigue and fretting fatigue conditions, for a ... -
A study into the reasons for process improvement project failures: results from a pilot survey
(Emerald, 2019-07-22)Purpose Process improvement initiatives, such as Lean, Six Sigma and Lean Six Sigma, typically have common characteristics that are carried through projects. Whilst a project’s performance is an important determinant of ... -
Supplier performance evaluation: Lessons from a large multinational organisation
(2007)Purpose - Progressive organisations are developing proactive supplier-based strategies in order to integrate key suppliers into their processes and systems. The purpose of this paper is to present an approach that helps ... -
Supporting systems innovation
(World Scientific Publishing, 2000)Many researchers and practitioners contend that organisations should respond to changing market need and create competitive advantage through innovation and creativity. Each year, organisations expend significant resources ... -
Technology Transfer for Product Life Cycle Extension: A Model for Successful Implementation
(2009)This paper examines the logistical and operational issues relating to technology transfer. It documents the specific problems encountered as well as the solution designed to overcome these problems. The paper presents a ... -
Towards holistic goal centered performance management in software development: lessons from a best practice analysis
(SciKA, 2015)There are strong motivating factors for more effective performance measurement practices in software development. Astute practices in this domain are lauded to improve efficiency and effectiveness. However previous studies ... -
Truncation error in mesh-free particle methods
(2006-06-25)A truncation error analysis has been developed for the approximation of spatial derivatives in smoothed particle hydrodynamics (SPH) and related first-order consistent methods such as the first-order form of the reproducing ... -
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 unified viscoplastic model for high temperature low cycle fatigue of service-aged P91 steel
(American Society of Mechanical Engineers, 2014-01-07)The finite element (FE) implementation of a hyperbolic sine unified cyclic viscoplasticity model is presented. The hyperbolic sine flow rule facilitates the identification of strain-rate independent material parameters for ... -
User acceptance of mandated technology: An analysis of the role of moderating factors
