  • Cloud cover : monitoring large-scale clouds with Varanus 

    Ward, Jonathan Stuart; Barker, Adam David (2015-07-14) - Journal article

    A Cloud Services Brokerage (CSB) acts as an intermediary between cloud service providers (e.g., Amazon and Google) and cloud service end users, providing a number of value adding services. CSBs as a research topic are in ...
  • Cloud-based e-Infrastructure for scheduling astronomical observations 

    Wetter, James Patrick; Akgun, Ozgur; Barker, Adam David; Dominik, Martin; Miguel, Ian James; Varghese, Blesson (IEEE Computer Society, 2015-08-31) - Conference item
    Gravitational microlensing exploits a transient phenomenon where an observed star is brightened due to deflection of its light by the gravity of an intervening foreground star. It is conjectured that this technique can be ...

    Fischer, Joel E.; Porcheron, Martin; Lucero, Andrés; Quigley, Aaron; Scott, Stacey D.; Ciolfi, Luigina; Rooksby, John; Memarovic, Nemanja (ACM Press - Association for Computing Machinery, 2016-02-27) - Conference item
    In the 25 years since Ellis, Gibbs, and Rein proposed the time-space taxonomy, research in the 'same time, same place' quadrant has diversified, perhaps even fragmented. This one-day workshop will bring together researchers ...
  • Combining touch and gaze for distant selection in a tabletop setting 

    Mauderer, Michael; Daiber, Florian; Krüger, Antonio (2013-04-27) - Conference paper
    Tabletop interaction with objects in and out of reach is a common real world as well as virtual task. Gaze as additional input modality might support this interactions on tabletops in terms of search, selection and ...
  • A comparison of the protein-coding genomes of two green sulphur bacteria, Chlorobium tepidum TLS and Pelodictyon phaeoclathratiforme BU-1 

    Wregglesworth, Kristin; Barker, Daniel (2015-10-14) - Journal article
    Background: Chlorobium tepidum and Pelodictyon phaeoclathratiforme are organisms within the green sulphur bacteria family, Chlorobiaceae, occupying very different habitats. It has recently been proposed that the genera ...
  • Computation of distances for regular and context-free probabilistic languages 

    Nederhof, Mark Jan; Satta, Giorgio (2008-05-01) - Journal article
    Several mathematical distances between probabilistic languages have been investigated in the literature, motivated by applications in language modeling, computational biology, syntactic pattern matching and machine learning. ...
  • Computation of infix probabilities for probabilistic context-free grammars 

    Nederhof, Mark Jan; Satta, Giorgio (Association for Computational Linguistics, 2011-07) - Conference item
    The notion of infix probability has been introduced in the literature as a generalization of the notion of prefix (or initial substring) probability, motivated by applications in speech recognition and word error correction. ...
  • Computing in matrix groups without memory 

    Cameron, Peter Jephson; Fairbairn, Ben; Gadouleau, Maximilien (2014-11-02) - Journal article
    Memoryless computation is a novel means of computing any function of a set of registers by updating one register at a time while using no memory. We aim to emulate how computations are performed on modern cores, since they ...
  • Computing in permutation groups without memory 

    Cameron, Peter Jephson; Fairbairn, Ben; Gadouleau, Maximilien (2014-11-02) - Journal article
    Memoryless computation is a new technique to compute any function of a set of registers by updating one register at a time while using no memory. Its aim is to emulate how computations are performed in modern cores, since ...
  • Computing partition functions of PCFGs 

    Nederhof, Mark Jan; Satta, Giorgio (2008-10) - Journal article
    We investigate the problem of computing the partition function of a probabilistic context-free grammar, and consider a number of applicable methods. Particular attention is devoted to PCFGs that result from the intersection ...
  • Container-based Cloud Virtual Machine benchmarking 

    Varghese, Blesson; Subba, Lawan Thamsuhang; Thai, Long Thanh; Barker, Adam David (IEEE Computer Society, 2016-04-04) - Conference item
    With the availability of a wide range of cloud Virtual Machines (VMs) it is difficult to determine which VMs can maximise the performance of an application. Benchmarking is commonly used to this end for capturing the ...
  • Context-based personalised settings for mobile location sharing
