  • Persistent identification and citation of software 

    Jones, Catherine Mary; Matthews, Brian; Gent, Ian; Griffin, Tom; Tedds, Jonathan (2016) - Journal article
    Software underpins the academic research process across disciplines. To be able to understand, use/reuse and preserve data, the software code that generated, analysed or presented the data will need to be retained and ...
  • The classification of partition homogeneous groups with applications to semigroup theory 

    André, Jorge; Araúo, Joāo; Cameron, Peter Jephson (2016-04-15) - Journal article
    Let λ=(λ1,λ2,...) be a partition of n, a sequence of positive integers in non-increasing order with sum n. Let Ω:={1,...,n}. An ordered partition P=(A1,A2,...) of Ω has type λ if |Ai|=λi.Following Martin and Sagan, we say ...
  • A dynamical definition of f.g. virtually free groups 

    Bennett, Daniel; Bleak, Collin (2016-02) - Journal article
    We show that the class of finitely generated virtually free groups is precisely the class of demonstrable subgroups for R. Thompson's group V . The class of demonstrable groups for V consists of all groups which can embed ...
  • PAEAN : portable and scalable runtime support for parallel Haskell dialects 

    Berthold, Jost; Loidl, Hans-Wolfgang; Hammond, Kevin (2016) - Journal article
    Over time, several competing approaches to parallel Haskell programming have emerged. Different approaches support parallelism at various different scales, ranging from small multicores to massively parallel high-performance ...
  • On optimality and construction of circular repeated-measurements designs 

    Bailey, Rosemary Anne; Cameron, Peter Jephson; Filipiak, Katarzyna; Kunert, Joachim; Markiewicz, Augustyn (2017-01) - Journal article
    The aim of this paper is to characterize and construct universally optimal designs among the class of circular repeated-measurements designs when the parameters do not permit balance for carry-over effects. It is shown ...
