Online Shop Presentation Modes for Consumer Decision Making and Flow Experiences
(2011-08-29)This research investigates the influence of product record presentation modes on the process and outcomes of online shopping. Experiments investigated eight combinations of product presentation modes by partnering with an ... -
An Ontological Framework for Interoperability of Health Level Seven (HL7) Applications: The PPEPR Methodology and System
(2012-09-25)Healthcare applications are complex in the way data and schemas are organised in their internal systems. Healthcare standards have been proposed to reduce heterogeneities between healthcare applications. Widely deployed ... -
Ontology learning for systems engineering body of knowledge
(NUI Galway, 2020-09-14)Systems engineering (SE) is a multidisciplinary and integrative approach that enables the successful realization of engineered systems. It encompasses fundamentals, principles, and models of foundational systems science, ... -
The ontology of technology: a Heideggerian perspective
(2016-06-30)The question concerning technology lies at the heart of human existence. As such it must take a central place in philosophy today. This importance, however, is veiled by a historical interpretation of technology as ... -
An open framework for multi-source, cross-domain personalisation with semantic interest graphs
(2014-12-28)The work in this thesis addresses new challenges and opportunities for online personalisation posed by the emergence of new infrastructures for sharing user preferences and for access to open repositories of data. As a ... -
Open-source bioelectronics for development of electrochemical biosensors and assays
(NUI Galway, 2019-02-20)This thesis presents steps in the development of open-source bioelectronics that gather together and combine in the demonstration of a system capable of operating a fully integrated wireless electrochemical biosensor. -
Open-source technologies and auxiliary electrodes for microbial fuel cell optimization
(NUI Galway, 2022-06-10)The purpose of this PhD thesis was to study direct waste-to-electricity transformations using microbial fuel cells (MFC) to obtain electricity as a byproduct of waste degradation. The extensive study of the literature ... -
OpenFOAM computational fluid dynamics studies on the ocean-atmosphere
(2015-09-05)Computational fluid dynamics (CFD) is the use of applied mathematics, physics, and computational software to visualize how a fluid flows around objects. CFD is based on the Navier-Stokes equations, which describe how the ... -
Openness and praxis: A situated study of academic staff meaning-making and decision-making with respect to openness and use of open educational practices in higher education
(NUI Galway, 2018-04-12)Open education seeks to improve educational access, effectiveness, and equality. The term ‘open educational practices’ (OEP) describes practices that include the creation, use and reuse of open educational resources (OER) ... -
Openness to experience and cardiovascular responsivity to acute psychological stress
(2017-02-07)Introduction. Research has implicated the personality trait of openness to experience - an individual’s propensity to be open to a variety of experiences, with a need to enlarge and examine experience - in the context ... -
Operant Variability:An Experimental Analysis of Consequential Control over Response Variation
(2012-09-29)This thesis investigated the differences in response variability between children and adolescents with a diagnosis of autism spectrum disorder (ASD) and neurotypical children and adolescents. It also examined ,methods for ... -
Operational and economic perspectives of pig manure and food waste anaerobic co-digestion
(2017-05-21)On-farm anaerobic co-digestion of pig manure (PM) and food waste (FW) is practiced at commercial scale across the world. However, there is a paucity of information regarding how to optimise such co-digestion systems in ... -
The optical development and calibration of the Galway Astronomical Stokes Polarimeter (GASP) as a multi-detector system for the polarimetric observations of variable optical sources
(2014-06-03)Polarised light from astronomical targets can yield a wealth of information about their source radiation mechanisms, and about the geometry of the scattered light regions. To date, stellar observations have focused, for ... -
Optical fibre dosimetry in external beam radiotherapy: Measurements and Monte Carlo simulation
