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 ... -
Using semantic mappings for semantic based publish/subscribe systems
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2009)Routing of information within heterogeneous, distributed network domains (e.g. communication networks, ubiquitous computing environments) is a key challenge that must be tackled for such environments to be successful. ... -
Strengthening real-time support in wireless networks
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2010)Wireless networks exhibit unpredictable and varying connection reliability as a result of node mobility and resultant changes in wireless signal propagation. Wireless signal propagation not only depends on the receiver’s ... -
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 ... -
Semantic-oriented cross-lingual ontology mapping
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2011)Ontologies support knowledge discovery, sharing and reuse among people and enable semantic interoperability between computer-based systems. To establish correspondences between knowledge concepts represented in ontologies, ... -
Identification and interpretation of figurative language with computational semantic models
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2014)This thesis is about the automatic extraction of metaphors as they appear in English text. This task is important to research in information retrieval, corpus linguistics and computational linguistics. The work was ... -
A framework for the delivery and evaluation of personalised multilingual information retrieval
(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 ... -
Interactive manycore photon mapping
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2011) -
Semantic-based service analysis and optimization
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2013)The need to autonomically optimize end user service experience in near real time has been identified in the literature in recent years. Service management systems that monitor end user service session context are deployed ... -
An application framework for mobile, context-aware trails
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2007)Time management strategies for planning and scheduling activities increase the effectiveness of either personal or corporate time use. Supporting techniques are commonly based around the use of prioritised to-do lists. ... -
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 ... -
Multi-policy optimization in decentralized autonomic systems
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2010)Autonomic computing systems are those that are capable of managing themselves based only on highlevel objectives given by humans. In such systems the details of how to meet their objectives, even in the face of changing ... -
FPGA message passing cluster architectures
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2010)This work investigates inter-Field Programmable Gate Array (FPGA) communication mechanisms, specifically the use of message passing and switched Ethernet communication mechanisms. Inter-FPGA communication is required in ... -
The multi-model, metadata driven approach to personalised eLearning services
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2005)One of the major obstacles in developing quality eLearning content is the substantial development costs involved and development time required [Marchionini, 95]. Educational providers, such as those in the university ... -
Active learning query selection with historical information
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2009)This work describes novel methods and techniques to decrease the cost of employing active learning in text categorisation problems. The cost of performing active learning is a combination of labelling effort and computational ... -
Foundations of ad hoc wireless networks
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2012)In this thesis we implement different process calculi to model ad hoc wireless networks. Each of these calculi considers different features of wireless systems, which are selected by focusing on the kind of applications ... -
The MOUSE approach : mapping ontologies using UML for system engineers
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2014)To address the problem of semantic heterogeneity, there has been a large body of research directed toward the study of semantic mapping technologies. Although various semantic mapping technologies have been investigated, ... -
High performance scientific computing using FPGAs for lattice QCD
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2007)The recent development of large FPGAs combined with the availability of a variety of FPGA-based non-integer arithmetic cores has made it possible to implement high performance matrix kernel operations on FPGAs. This thesis ... -
Adaptive eLearning for grid computing
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2012)Adaptive eLearning appears well suited to Grid education because of the distributed and heterogeneous nature of grid users and their asynchronous training demand. This thesis explores the application of adaptive eLearning ... -
MUSE : platform for mobile computer supported collaborative learning
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2011)Traditionally much research on computer supported collaborative learning, CSCL, focused on either learning through distant collaboration or face-to-face collaboration sharing a computer. A new and emergent area within CSCL ...
