Language support for communicating transactions
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2016)In the context of databases, a transaction is a sequence of data operations that are executed atomically and in isolation: either all operations are executed or none is; and their effects are visible to the environment ... -
Learner perceptions of successful engagement in undergraduate computer science education : a grounded theory
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2013)Computer science degree programs have proliferated due to the demands of industry and the pressures placed on higher education institutions by national governments. In tandem with this, the technological familiarity presumed ... -
Learning object-oriented programming from the students' perspective
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2009)Computer programming and programming languages are core modules in most undergraduate Computer Science and Engineering degree courses. However, learning to program is a complex activity as it involves the understanding and ... -
Learning temporal sentiment from business news : a computational approach
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2017)This thesis concerns is about the analysis of textual sentiment using computational approaches. Textual sentiment reflects the opinions and attitudes expressed through textual communications. With the advent of the Internet ... -
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 ... -
Level of detail representations and variation methods for the rendering of large animated crowds
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2011)The simulation of large crowds of characters is an important topic in the field of real time rendering as games and movies strive for more realistic populated scenes. Displaying a city scene with a large crowd enhances the ... -
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 ... -
Leveraging Content from Open Corpus Sources for Technology Enhanced Learning
(Trinity College Dublin, University of Dublin, Trinity College, 2009)As educators attempt to incorporate the use of educational technologies in course curricula, the lack of appropriate and accessible digital content resources acts as a barrier to adoption. Quality educational digital ... -

Linear transformations of semantic spaces for word-sense discrimination and collocation compositionality grading
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2015)Latent Semantic Analysis (LSA) and Word Space are two semantic models derived from the vector space model of distributional semantics that have been used successfully in word-sense disambiguation and discrimination. LSA ... -
Link quality prediction in mobile ad hoc networks
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2007)Link quality prediction (LQP) is effective in masking topology changes in wireless mobile ad hoc networks (MANETs) as previously shown in reducing packet latency in proactive routing. However, most existing LQP algorithms ... -
Load balancing and rate limiting based algorithms for improving cloud computing performance
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2012)The cloud computing paradigm has recently become an increasing popular method for the delivery of internet services. While the increased utilisation of the cloud has made it easier for cloud operators to recover their ... -
Location aware multimedia narratives
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2008)During the 1980s and the early 1990s, a considerable number of technology and application trends were concerned with location transparency and virtual spaces, overcoming the limitations of the physical space. Artists and ... -
Lock-free internal binary search trees with memory management
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2012)The current design trend in microprocessor systems is to add more CPU cores thus increasing parallel execution resources. Although this allows many sequential programs to be run in parallel, it can be challenging to use ... -

Making Personalised Flight Recommendations using Implicit Feedback
(University of Dublin, Trinity College. School of Computer Science and Statistics, 2004-10)As e-commerce has become more popular, the problem of information overload has come to the fore. Recommender systems that reduce the information overload problem are becoming more common. However, the problem with many ... -
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 ... -
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 ... -
Mathematical foundations of differential privacy
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2017)Sensitive personal data collected about us has the potential to give great insight into human behaviour, but it remains a challenge to publish such information while guaranteeing (i) individuals’ privacy and (ii) data ... -
Mean-Shift Tracking for Surveillance: Evaluations and Enhancements
(University of Dublin, University of Dublin, Trinity College, 2011)Mean-shift tracking is a technique for following an object of interest as it moves through a video sequence. It is a gradient ascent approach that models the image region to be tracked by its colour histogram. In this ...
