    Hughes, Barbara (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 

    Doyle, Michael J. (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 

    Callanan, Owen (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 ...
  • Hybrid feature-based transform coding of grey-level images 

    Fox, Ivan (Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2001)
    The objective of image compression is to achieve the minimum possible bit-rate, within certain bounds of computational complexity, and with a tolerable degree of distortion. In very low bit-rate coding it is generally ...
  • Hybrid representations and perceptual metrics for scalable human simulation 

    Dobbyn, Simon (Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2006)
    The simulation of large crowds of humans is important in many fields of computer graphics, including real-time applications such as games, as they can breathe life into otherwise static scenes and enhance believability. ...
  • A Hybrid Software and Hardware System for Collision Detection 

    Woulfe, Muiris (University of Dublin, Trinity College, University of Dublin, Trinity College, 2010)
    Collision detection is a fundamental problem in myriad applications, spanning a wide variety of fields. Although the core concept is relatively straightforward, significant complexities result from the demand for interactive ...
  • Identification and interpretation of figurative language with computational semantic models 

    Gerow, Aaron (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 and interpreting context on the Web : an application-driven approach 

    Kelleher, Daniel (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 ...
  • Identifying translation effects in English natural language text 

    Lynch, Gerard (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 ...
  • Improved optimisation of density forecasting models using multi-objective search with applications in risk management 

    Carney, Michael (Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2007)
    Density forecasting is becoming an increasingly popular method of prediction. Density forcasting models produce a probability density function estimate of a future event rather than a standard point estimate. Given that ...
