  • A case study of Action Design Research for privacy risk management engineering 

    Moloney, Maria (Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2014)
    This dissertation presents a case study concerning the application of the Action Design Research (ADR) methodology to the development of a privacy-enhanced electronic postal system. As part of the ADR project, a model of ...
  • A convex optimisation approach to optimal control in queueing systems 

    Valls, Víctor (Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2017)
    Convex optimisation and max-weight are central topics in networking and control, and having a clear understanding of their relationship and what this involves is crucial from a theoretical and practical point of view. In ...
  • A cross-cultural exploration of online community newcomer behaviour 

    Gallagher, Silvia Elena (Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2016)
    As Internet use has become globally pervasive, the literature suggests that national culture is having an impact on online community communication practices. The importance of researching national culture in these spaces ...
  • A delay and disruption tolerant transport layer protocol 

    Farrell, Stephen (Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2008)
    The area of delay-tolerant networking (DTN) is concerned with highly challenged networks in which application layer "sessions" commonly lack contemporaneous end-toend connectivity. For example, efforts to create networks ...
  • A dependency modelling approach for the management of ontology-based integration systems 

    Boran, Aidan (Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2011)
    Ontology-based approaches that formally represent the meaning of information in a system, offer the hope of dealing with semantic heterogeneity when integrating heterogeneous data sources [Halevy 2001, Noy 2004, Wache et ...
  • A diagnostic for the general linear model : an application to Time Series 

    Sullivan, Carl (Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2002)
    An outlier is an observation which is thought to be unusual. The detection of such extreme values is an important issue. Developing a model based on data containing even a single outlier can seriously bias population ...
  • A domain knowledge driven information uplift approach for network monitoring 

    Song, Yuqian (Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2014)
    With the advance of modern network technologies, people now enjoy increased convenience whilst occasionally suffering annoyance from network issues by lacking domain expertise. In the Home Area Network (HAN), these issues ...
  • A flexible explanation system for case-based reasoning 

    Nugent, Conor (Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2006)
    Artificial Intelligence systems have reached a level of sophistication and accuracy which means that they can now be confidently used as decision aids in real world situations. However, although these systems are accurate, ...
  • A flexible framework for distributed shared objects 

    Weber, Stefan (Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2002)
    A distributed shared memory (DSM) system ensures the consistency of shared data in a distributed system while providing the programming paradigm of a single-processor system. Recent DSM systems provide increasingly more ...
  • A framework for instrument monitoring on the grid 

    Kenny, Stuart (Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2006)
    Grid computing enables the selection and aggregation of a wide variety of geographically distributed resources as a single unified computing resource, for solving large scale compute and data intensive computing ...
  • A framework for the delivery and evaluation of personalised multilingual information retrieval 

    Ghorab, Mohammed Rami (Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2014)
    The amount of content provided in different languages on the Web is growing every day. The best answer to a user's query may not necessarily be available in his/her own language, but may reside in the diverse, multilingual ...
  • A generic framework for grid-enabled visualisation and computational steering, and its characterisation 

    Watson, Ronan (Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2011)
    This thesis presents a generic framework for grid-enabled visualisation and computational steering that is amenable to characterisation using mathematical models based on benchmarked resources. The models enable designers, ...
  • A holistic approach to mobile robot navigation using omnidirectional vision 

    Winters, Niall (Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2002)
    This dissertation presents a novel methodology for vision-based robot navigation. One of the key observations is that navigation systems should be designed through a holistic approach, encompassing aspects of sensor design, ...
  • A knowledge-light approach to regression using case-based reasoning 

    McDonnell, Neil (Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2007)
    Case-based reasoning (CBR) is among the most influential paradigms in modern machine learning. It advocates a strategy of storing specific experiences in the form of cases, and solving new ...
  • A model for mobile spatial services 

    Linehan, Éamonn (Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2009)
    Mobile context-aware computing is a paradigm in which mobile devices have access to information, known as context, about the situation in which they are being used, and dynamically adapt application behaviour to support ...
  • A multi-faceted model of trust that is personalisable and specialisable 

    Quinn, Karl (Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2007)
    Trust is a term that is open to a wide range of subjective interpretations, and it has therefore been argued that “trust is a fashionable but overloaded term with lots of intertwined ...
  • A new method to implement Bayesian inference on stochastic differential equation models 

    Joshi, Chaitanya (Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2011)
    Stochastic differential equations (SDEs) are widely used to model numerous real-life phenomena. However, transition densities of most of the SDE models used in practice are not known, making both likelihood based and ...
  • A policy based framework for real time charging in next generation networks 

    Lee, Brian (Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2005)
    The telecommunications landscape is undergoing a period of dramatic change. This change has been ongoing for a number of years and is driven by a combination of industry deregulation and technology advance. The net effect ...
