Policy based management for dynamic organisations
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2009)Policy-Based Management (PBM) is a recent development in systems and network management research which aims to address the challenge of efficiently managing complex and heterogeneous information systems. Broadly speaking, ... -
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 ... -
Making uniqueness typing less unique
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2009)Computer science distinguishes between two major programming paradigms: imperative and functional programming. Central to imperative programming is the notion of some form of state (or memory) together with a list of ... -
Procedural modelling of urban environments
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2012)Procedural modelling of urban environments has become an important topic in computer graphics. With the ever increasing demand for larger and more realistic content in games and movies, the time and cost to model urban ... -
Enhancing real-time focus and context direct volume rendering
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2013)Direct volume rendering is a challenging problem both due to the technical difficulty of displaying large volume datasets on limited hardware and due to the difficulty of rendering such complex information in a manner which ... -
Managing adaptive web services using semantic models and automated policy refinement
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2010)There is an increasing demand for web services to be more flexible, in order to suit fast changing business needs and user requirements. Web services need to be adaptive to changes in context, so as to provide web service ... -
Unstructured decentralised data distribution in wireless sensor networks
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2012)Next generation Wireless Sensor Networks will operate as self-regulated ad hoc networks of tiny devices that sense, actuate and coniinunicate in a collaborative fashion. These networks will also be required to operate in ... -
A technology enhanced learning framework for enterprise performance optimisation
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2012)Enterprise perfornnance optimisation is critical for organisations to survive and prosper in today's competitive global market-place. While this is true for all organisations, the need is even greater for the Small and ... -
Responsive aggregate defence for denial of service attacks
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2011)The Internet is the main provider of information, communication and media services for an increasing percentage of the world's population. Its architecture is based on packet switching principles and employs a layered, ... -
The mobiledna (digital narrative approach) : supporting collaborative creativity in mobile moving media production
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2009)Collaboration and creativity are beneficial for learning. While collaboration involves conflict, articulation and co-construction, creativity banks on the interplay between divergent and convergent thinking. Collaborative ... -
A holistic approach to mobile robot navigation using omnidirectional vision
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2002)This dissertation presents a novel methodology for vision-based robot navigation. One of the key observations is that navigation systems should be designed through a holistic approach, encompassing aspects of sensor design, ... -
A flexible framework for distributed shared objects
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2002)A distributed shared memory (DSM) system ensures the consistency of shared data in a distributed system while providing the programming paradigm of a single-processor system. Recent DSM systems provide increasingly more ... -
Explaining the output of ensembles on a case by case basis
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2003)This thesis introduces a novel method for explaining the predictions of ensembles of artificial neural networks on a case by case basis. Current research is primarily directed towards building global model, that is, models ... -
Unified pattern recognition and its application to handwriting recognition
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2002)The goal of this thesis is the design and the implementation of a visual pattern recognition system based on the analysis of fundamental principles of human perception. The system must simultaneously be psychologically ... -
Supporting meta-types in a compiled, reflective programming language
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2002)Software engineering in a distributed, heterogeneous environment is faced with a number of challenges. With distribution comes the need for synchronisation, transactions, and fault-tolerance while support for different ... -
Supporting unanticipated dynamic adaptation of object-oriented software
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2004)Dynamic adaptation of a running program allows the program's behaviour to be changed without stopping or restarting it. Examples of the need for this are in updating long-running systems that cannot be halted and in adapting ... -
Automated application of design patterns : a refactoring approach
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2001)Software systems have to be flexible in order to cope with evolving requirements. However, since it is impossible to predict with certainty what future requirements will emerge, it is also impossible to determine exactly ... -
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 ... -
Towards semantic health records
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2004)The benefit of information search and knowledge retrieval using the World Wide Web (WWW) has steadily declined in recent years due to the vast amount of unstructured data. The task of locating relevant information on the ... -
Time adaptive dynamic simulation of rigid bodies
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2004)Traditionally the maintenance of high constant frame rates for real-time performance relied on level of detail simplification, usually performed within the geometry domain. However, simplification can also be achieved for ...
