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 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 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 ... -
Using Wikis to facilitate team work: German and Irish students' perspectives
(All Ireland Society for Higher Education (AISHE), 2011)Enhanced collaboration among multicultural European countries is necessary for effective enterprise development and innovation. The current climate of an increasingly competitive global economy provides opportunities to ... -
Value chain migration from production to product centred operations: an analysis of the Irish medical device industry
(2006)The medical device industry in Ireland is largely confined to manufacturing operations. This narrow focus limits the competitiveness of the industry in Ireland and consequently poses a threat to development and growth. ... -
Virtual team environment for collaborative research projects
(2006)One of the main limiting factors that reduce the potential output the innovation projects, involving different organisations and individuals from different geographical areas, is the poor communication and knowledge sharing ... -
Void distributions and permeability prediction for rotationally moulded polymers
(SAGE, 2014-01-22)An experimental study of void distributions for rotationally moulded polyethylene is presented. The effects of key variables such as maximum process temperature and nominal wall thickness (via powder mass) are studied. ... -
Workplace Exposure to Bioaerosols in Podiatry Clinics
(Oxford Journals, 2012-01-03)The aim of this study was to design and execute a pilot study to collect information on the personal exposure levels of podiatrists to microbial hazards in podiatry clinics and also to assess health and safety knowledge ... -
An XFEM-Based Methodology for Fatigue Delamination and Permeability in Composites
(2014)Carbon fibre reinforced polymers (CFRP) are one of the prospective material families being investigated for use in the fuel tanks of future reusable space launch vehicles (RSLVs). The extreme thermo-mechanical loading that ...
