OM2R : semantic documentation of ontology mapping lifecycle to support retrieval and reuse of ontology mappings
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2014)Ontology mappings are of critical importance for the Linked Data and the Semantic Web communities as they can help to mitigate the effects of heterogeneities, which are a major obstacle to the promise of interoperability ... -
On coordination disambiguation in a generative parsing model, with memory-based techniques for parameter estimation.
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2007)This thesis is concerned with improving existing generative history-based probability models' treatment of noun phrase coordination and the development of memory based techniques for model parameter estimation. Lexicalised ... -
On the dynamic multiple intelligence informed personalization of the learning environment
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2006)Educational research informs us "one size does not fit all" (Reigeluth, 1996). It states that learners, reflecting individual traits, possess different learning characteristics, process and represent knowledge in different ... -
On-demand multimedia server clustering using dynamic content replication
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2004)This thesis examines the provision of on-demand multimedia streaming services using clusters of commodity PCs. In the proposed HammerHead multimedia server cluster architecture, a dynamic content replication policy is ... -
Ontology and information retrieval : the case of the fine arts
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2012)This thesis explores methods of computational ontology for information retrieval in a knowledge rich domain. The example case we selected for our study is the domain of the fine arts. Various aspects were under examination, ... -
Open Prolog: a Structure-Sharing Prolog for the Macintosh
(University of Dublin, Trinity College. Department of Computer Science, 2005-08)This thesis explores the design and implementation of a Prolog system with just one mode of program execution rather than the two modes of execution? interpretation and compilation?present in most Prolog implementations ... -
Opportunistic service composition in dynamic ad hoc environments
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2013)Mobile and embedded devices capture, process, and exchange sensory data about their operating environment, making them suitable service providers for ubiquitous computing. In particular, composing services that are hosted ... -
Optical IP switching
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2008)Improvements in the optical transmission technology, over the past fifteen years, have substantially facilitated the development and worldwide deployment of the Internet, by reducing the cost of data transport. The exponential ... -
Optimizing multimedia content delivery over next-generation optical networks
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2015)This thesis analyzes the performance of a Peer-to-Peer (P2P) multimedia content delivery system for a network architecture based on next-generation Passive Optical Networks (PONs). A PON is an optical access technology ... -
PAM-AID - A study in human-machine cooperative behaviour
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2001)The research described in this thesis attempts to address the needs of a growing number of people with both a visual impairment and a mobility impairment. These people tend to live a very inactive lifestyle, often confined ... -
Parasitic routing : using social network analysis for routing in disconnecting delay-tolerant MANETs
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2007)Message delivery in sparse Mobile Ad hoc Networks (MANETs) is difficult due to the fact that the network graph is rarely (if ever) connected. As a consequence, a full end-to-end path between nodes may not exist at any given ... -
Patient-centred clinical validation using autonomous socialising knowledge agents

Peer assisted multicast streaming on-demand applications
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2016)On-demand multimedia streaming applications allow users to select and view content at a time of their choosing and to control the playback of this content. This level of control typically requires that each user receives ... -
Perceptually guided authoring of image based representations
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2007)The creation of digital visual content has become a major activity in a broad range of industries. A huge quantity of labour is invested in related tasks, from modeling to de-noising of captured data. There has been ... -
Perceptually-Adaptive Collision Detection for Real-time Computer Animation
(Unversity of Dublin, Trinity College Dublin. Department of Computer Science, 1999)The aim of interactive animation systems is to create an exciting and real experience for viewers, to give them a feeling of immersion, of "being there". The tendency in the past has been to attempt to achieve this by ... -
Personalised eLearning development environments
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2006)Personalised eLearning is seen as a key element for next generation educational programmes [DFES, 2005]. The goal of personalised eLearning is to support eLearning content, activities and collaboration, adapted to the ... -
PiCSE : a framework for simulation and emulation of pervasive computing applications
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2015)The field of pervasive computing is changing rapidly, with the proliferation of and advances in hardware and communication technologies resulting in a shift towards a large-scale, heterogeneous pervasive computing world ... -
Planning and adaptation of virtual human character motion
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2013)This thesis covers some work on planning and adapting motions for a virtual 3d human character. The motivation is to use the physical features of the motion to drive both the planning of motion sequences and the subsequent ... -
Plausible crowd and group formations
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2011)Applications using real-time virtual crowds can be found in many areas, including the entertainment industry, for urban planning and health and safety purposes. In some of these applications, where the goal is to replicate ...
