Intuitive human centric governance of pervasive computing environments
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2007)Pervasive computing proposes that in the future, human beings will be immersed in a technology rich environment, where computing power will be embedded in devices all around us. This thesis examines how such technology ... -
Exploiting commodity parallel hardware for computer graphics applications and architectures
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2007)The processing power available in today's commodity parallel hardw are has enabled realism and detail in graphics that has never before been possible. With the advent of the progrannnable Graphics Processor Unit (GPU), the ... -
Service management in dynamic e-business environments
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2006)Internet technologies are facilitating the development of an environment where companies are outsourcing activities that are not a part of their core competencies to third-party service providers. Customers and service ... -
A flexible explanation system for case-based reasoning
(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, ... -
Biometric retrieval of cryptographic keys
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2006)The problem statement addressed in this thesis is the creation of the first biometric key retrieval scheme capable of protecting private keys used in all three types of public-key cryptosystems: those that rely on the ... -
Discovery of autonomous semantic services in mobile ad hoc networks
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2007)Mobile Ad Hoc Networks (MANETs) are dynamic networks in which mobile devices with wireless connnunication capabilities cooperate to provide spontaneous connectivity. In particular, a mobile ad hoc network can be considered ... -
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 ... -
Realistic crowd animation : a perceptual approach
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2006)Real-time applications such as games or urban simulations arc often highly complex in nature. User expectations grow year by year, along with a concomitant desire for added realism. Due to the performance limitations of ... -
Correlation-based stereoscopic disparity estimation with high-performance commodity hardware
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2008)Stereoscopic depth reconstruction is the estimation of scene depth from at least two images of the scene taken at different viewpoints. The main computational problem is identification of matching pixels between the images. ... -
Virtual Worlds: A New Environment for Constructionist Learning
(2019)Virtual worlds have the potential to provide a new environment in which to engage learners in constructionist activities. However, they were not designed for education and have features and affordances which are not ... -
Reducing overfitting in wrapper-based search
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2006)The benefits of wrapper-based techniques for feature selection are well established. However, it is acknowledged that overfitting can occur in feature selection using the wrapper method when there is a limited amount of ... -
Multiresolution liquid simulation and rendering
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2008)Current approaches to real-time liquid simulation are based on solutions to the two-dimensional wave equation. In this thesis, we introduce a new, explicit solution method for the shallow water equations that achieves more ... -
A policy based framework for real time charging in next generation networks
(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 ... -
Identifying and interpreting context on the Web : an application-driven approach
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2008)This work describes the use of contextual information in Web document processing. Contextual information is defined as the contents of a 'context set' of a document of interest on the Web. The context set of a document is ... -
Saliency determination for computer graphics : an experimental approach
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2006)In the computer graphics realm complex objects are abundant, but often need to be simplified in order to be displayed interactively. As the human visual system is far from flawless, advantage can be taken of its weaknesses ... -
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 ... -
Towards automatic and dynamic meta-object protocol composition in a compiled, reflective programming language
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2005)This thesis describes a reflective programming model that provides a solution to the problem of automatic and dynamic metaobject composition in a compiled reflective prograrnming language, Iguana/C++. Meta-object protocols ... -
Level of detail techniques for real-time urban simulation
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2005)Real-time urban simulation is an area of computer graphics with many applications, from city planning and emergency response to computer gaming. The task of creating and running a believable simulation of an urban area is ... -
A state-of-the-art toolkit for document clustering
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2007)Cluster analysis refers to a family of procedures which are fundamentally concerned with automatically arranging data into meaningful groups. These procedures are increasingly being employed in knowledge discovery tasks ... -
Learning to annotate music files using content based retrieval systems and wavelet packet approximations of the input signals
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2005)This thesis presents an inter-disciplinary approach to the problem of music parametrisation for information representation and retrieval. Signal analysis and machine learning techniques are combined in the context of ...
