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 ... -
Effects of social structure on establishing lexical conventions in a computational model of task-oriented primeval dialogue
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2013)In the field of language evolution, the only way of obtaining empirical data for most of its parts is with the help of computational models and simulations. As a consequence, a large number of different modelling approaches ... -
Enforcing cooperation between nodes in mobile ad hoc networks
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2013)Traditional infrastructure-based networks are formed around an infrastructure of static, dedicated components that connect the individual end points such as desktop computers and servers. The exponential rise in the number ... -
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 ... -
Extending event based programming for sensor-driven applications in resource-constrained environments
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2011)The ubiquitous computing vision which began with Weiser and its evolution since predicts large quantities of sensors, actuators and computational devices embedded in our environment enabling advanced applications which ... -
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 ... -
Formal polytypic programs and proofs
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2010)Polytypic or datatype-generic programming is a form of generic programming where we abstract over the shape of datatypes: we define functions by induction over the structure of datatypes. In this thesis we show how to ... -
Formalising a real-time coordination model
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2015)The subject of this thesis pertains to coordination in systems of entities characterised by mobile, real-time behaviour and unreliable communication over a wireless network. Such systems are now being deployed both in ... -
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 ... -
Generating sentiment lexica : evaluating approaches with genetic algorithms and particle swarm optimization
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2014)This thesis examines the application of sentiment analysis towards financial news. The primary goal within the field of sentiment analysis is to develop a methodology by which the sentiment or emotional view being expressed ... -
Group communication for cooperative automated vehicles
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2014)The automotive industry has increasingly adopted computer technology to enhance the safety and efficiency of vehicles. Using sensors and electronic control systems, vehicles can become partially or fully automated, taking ... -
Hard real-time communication for mobile ad hoc networks
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2007)The increasing availability of wireless local area networking, particularly ad hoc networking, has lead to the evolution of new application domains, such as inter-vehicle communication and communication between autonomous ... -
Hardware support for power and area efficient construction of high-quality bounding volume hierarchies
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2014)Rendering methods basal on ray-tracing hold the promise of great realism for interactive applications. However, these algorithms still involve a considerable computational cost relative to the capabilities of today�۪s ... -
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 ... -
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 ... -
Identifying translation effects in English natural language text
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2013)With the rise in popularity of applying machine learning methods to problems in textual stylometry, the increased availability of machine-readable corpora and the emerging benefits of research on corpora of translated text ... -
Influencing user perception using real-time adaptive abstraction
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2010)Real-time applications such as games, medical or technical visualisations and urban simulations can often be highly complex in nature. This can lead to too much visual data being presented to the user at once, which can ... -

Interaction-based information retrieval in multimodal, online, artefact-focused meeting recordings
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2007)Traditional search operations, topic detection or summarisation of meeting recordings are generally performed using segmentation and indexing techniques originally developed in the field of Multimedia Information Retrieval. ... -
