An image analysis and machine learning approach to measuring the quality of individual colonoscopy procedures
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2013)The measurement of quality in colonoscopy is an active topic in medical research. Studies report significant miss rates in the detection of colorectal lesions. This has raised the concern among gastroenterologists that the ... -
An investigation of and a hybrid recommender system for evaluating adaptive E-Learning systems
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2015)A key problem with research in the field of adaptive systems is the inconsistency of evaluation applied to such systems. A fact that is well established by expert evaluators is that adaptive systems cannot be evaluated as ... -
Authentication and accounting for network services in next-generation mobile networks
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2005)Mobile communications technologies are in a constant state of flux. They have evolved from simple one-way radio communications systems, to today’s third-generation networks that support digital signaling and multimedia ... -
Authorization management for pervasive computing
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2006) -
Automatic reasoner composition and selection
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2011)The development of OWL and OWL reasoning technologies has enabled them to be used for knowledge base (KB) modelling and/or intelligent data processing in applications of various areas. However the computation and ... -
Behavioural equivalences for web services
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2013)This thesis is a foundational and systematic investigation of the principles which ensure that a piece of communicating software can be replaced by another piece of communicating software, without hindering the operations ... -
Cashua : integrating semantics and content-based networking for context distribution
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2009)To support a vision of ubiquitous computing where computers fade into the background, context systems must provide information to highly mobile people and devices in ubiquitous computing environments. In these environments, ... -
CAWriter : using an Activity System perspective to inform the design of tools to support early career Ph.D. candidates
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2014)This thesis adheres to the view that the purpose of a Ph.D. is to both make a significant contribution to knowledge and to provide the candidate with the skills necessary to conduct "independent" research, culminating ... -
Certainty assessment in informal language
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2015)This research studied linguistic hedges in informal language style. Hedges are expressions that show a weakened commitment of speakers with respect to what they are saying. This modification in their commitment is made for ... -
Collaborative requirements elicitation to foster shared understanding
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2015)Fostering shared understanding of how to support organisational change involves a complex interaction of stakeholders in order to achieve alignment of business processes and IT infrastructure. Collaboration ... -
Collaborative, contextual, and technology-mediated mathematics learning activities : design heuristics and effects on student engagement
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2015)This dissertation describes an approach to mathematics activity design that aligns the affordances of off-the-shelf technologies with relevant mathematics pedagogy. The aim is to create transformative learning experiences ... -
Command and control for grid infrastructures
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2008) -
Context-aware power management
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2007)With more and more computing devices being deployed in buildings there has been a steady rise in buildings’ electricity consumption. These devices not only consume electricity but also produce heat, which increases loading ... -
Context-informed semantic interoperation
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2010)A common trend in modern applications is the move towards more mobile, adaptive, customisable software. The evolution of software from static, invariant tools for narrow portions of a task to adaptive, open interaction ... -
Decentralized optimization of fluctuating urban traffic using reinforcement learning
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2010) -
Design and implementation of an ahead-of-time compiler for PHP
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2010)In recent years the importance of dynamic scripting languages -such as PHP, Python, Ruby and Javascript - has grown as they are used for an increasing amounts of sortware development. Scripting languages provide high-level ... -
Detecting restriction class correspondences in Linked Open Data
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2014)The Linked Open Data (LOD) project has made a broad range of knowledge available on the World Wide Web as open datasets, using a common format and linked in such a manner that it is a simple task to explore and integrate ... -
Distributed shared memory architectures and global performance state estimation
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2006)Invasive and non-invasive methods may be applied to measure and analyse the performance of hardware Distributed Shared Memory (DSM) systems. This thesis presents novel solutions for both methods and discusses the ... -
Exploiting heterogeneity in peer-to-peer systems using gradient topologies
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2009)A peer-to-peer system can be defined as an overlay network built by a set of nodes on top of a physical network infrastructure and its operating protocols, such as the Internet. In a peer-to-peer network, each node ... -
Fibrations of predicates and bicategories of relations
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2014)We reconcile the two different category-theoretic semantics of regular theories in predicate logic. A 2-category of regular fibrations is constructed, as well as a 2-category of regular proarrow equipments, and ...
