    • Fibrations of predicates and bicategories of relations 

      Lawler, Finn (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 ...

    • Addressing scalability in Mobile Ad hoc Networks 

      Kenny, Warren (Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2012)
      Mobile Ad hoc Networks (MANETs) are wireless networks comprised of nodes which exhibit varying mobility and availability. Such networks are highly volatile, with network membership changing unpredictably over time. As ...

    • Hard real-time communication for mobile ad hoc networks 

      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 ...

    • A new method to implement Bayesian inference on stochastic differential equation models 

      Joshi, Chaitanya (Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2011)
      Stochastic differential equations (SDEs) are widely used to model numerous real-life phenomena. However, transition densities of most of the SDE models used in practice are not known, making both likelihood based and ...

    • A framework for instrument monitoring on the grid 

      Kenny, Stuart (Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2006)
      Grid computing enables the selection and aggregation of a wide variety of geographically distributed resources as a single unified computing resource, for solving large scale compute and data intensive computing ...

    • Lock-free internal binary search trees with memory management 

      Howley, Shane Valentine (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 ...

    • Context-aware power management 

      Harris, Colin (Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2007)
      With more and more computing devices being deployed in buildings there has been a steady rise in buildings’ electricity consumption. These devices not only consume electricity but also produce heat, which increases loading ...

    • Using semantic mappings for semantic based publish/subscribe systems 

      Guo, Song (Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2009)
      Routing of information within heterogeneous, distributed network domains (e.g. communication networks, ubiquitous computing environments) is a key challenge that must be tackled for such environments to be successful. ...

    • Strengthening real-time support in wireless networks 

      Gleeson, Mark (Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2010)
      Wireless networks exhibit unpredictable and varying connection reliability as a result of node mobility and resultant changes in wireless signal propagation. Wireless signal propagation not only depends on the receiver’s ...

    • Opportunistic service composition in dynamic ad hoc environments 

      Groba, Christin (Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2013)
      Mobile and embedded devices capture, process, and exchange sensory data about their operating environment, making them suitable service providers for ubiquitous computing. In particular, composing services that are hosted ...

    • Semantic-oriented cross-lingual ontology mapping 

      Fu, Bo (Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2011)
      Ontologies support knowledge discovery, sharing and reuse among people and enable semantic interoperability between computer-based systems. To establish correspondences between knowledge concepts represented in ontologies, ...

    • 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 ...

    • A framework for the delivery and evaluation of personalised multilingual information retrieval 

      Ghorab, Mohammed Rami (Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2014)
      The amount of content provided in different languages on the Web is growing every day. The best answer to a user's query may not necessarily be available in his/her own language, but may reside in the diverse, multilingual ...

    • Interactive manycore photon mapping 

      Fabianowski, Bartosz (Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2011)

    • Semantic-based service analysis and optimization 

      Fallon, Liam (Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2013)
      The need to autonomically optimize end user service experience in near real time has been identified in the literature in recent years. Service management systems that monitor end user service session context are deployed ...

    • An application framework for mobile, context-aware trails 

      Driver, Cormac (Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2007)
