  • van Rijn, Jan N.; Holmes, Geoffrey; Pfahringer, Bernhard; Vanschoren, Joaquin (Springer International Publishing, 2014)
    We explore the possibilities of meta-learning on data streams, in particular algorithm selection. In a first experiment we calculate the characteristics of a small sample of a data stream, and try to predict which classifier ...
  • Delamore, Baden; Ko, Ryan K.L. (Institute of Electrical and Electronics Engineers Inc., 2015)
    The reliance on Web applications has increased rapidly over the years. At the same time, the quantity and impact of application security vulnerabilities have grown as well. Amongst these vulnerabilities, SQL Injection has ...
  • Yongchareon, Sira; Ngamakeur, Kan; Liu, Chengfei; Chaisiri, Sivadon; Yu, Jian (Springer Verlag, 2014)
    To execute an artifact-centric process model, current workflow execution approaches require it to be converted to some existing executable language (e.g., BPEL) in order to run on a workflow system. We argue that the ...
  • Akram, Raja Maeem; Markantonakis, Konstantinos; Mayes, Keith (IOS Press, 2013)
    Remote attestation mechanisms are well studied in the high-end computing environments; however, the same is not true for embedded devices-especially for smart cards. With ever changing landscape of smart card technology ...
  • Sun, Quan; Pfahringer, Bernhard (Springer Verlag, 2014)
    The Pairwise Meta-Rules (PMR) method proposed in [18] has been shown to improve the predictive performances of several metalearning algorithms for the algorithm ranking problem. Given m target objects (e.g., algorithms), ...
  • Suppers, Joris; Apperley, Mark (CRPIT, 2014)
    The concept of casual screen sharing is that multiple users can cast screen images from their personal hand-held devices on to a large shared local screen. It has applications in personal and business domains where documents ...
  • Dean, Jesse; Apperley, Mark; Rogers, Bill (CRPIT, 2014)
    Virtual worlds show promise for conducting meetings and conferences without the need for physical travel. Current experience suggests the major limitation to the more widespread adoption and acceptance of virtual conferences ...
  • Hinze, Annika; Michel, Yann; Schlieder, Torsten (Australian Computer Society Inc, 2006)
    Publish/subscribe systems filter published documents and inform their subscribers about documents matching their interests. Recent systems have focussed on documents or messages sent in XML format. Subscribers have to be ...
  • Luz, Saturnino; Masoodian, Masood; Cesario, Manuel (Taylor & Francis, 2015)
    The development and deployment of information technology, particularly mobile tools, to support collaboration between different groups of healthcare professionals has been viewed as a promising way to improve disease ...
  • Masoodian, Masood; Apperley, Mark; Frederikson, Lesley (Department of Computer Science, The University of Waikato, 1995)
    A study has been carried out to identify the effects of different human-to-human communication modes on dyadic computer supported group work. A pilot study evaluated an available shared work-space software system, supplemented ...
  • Litvinenko, Yuri E.; Wheatland, M.S. (The American Astronomical Society, 2015)
    Disintegration of sunspots (and starspots) by fluxtube erosion, originally proposed by Simon and Leighton, is considered. A moving boundary problem is formulated for a nonlinear diffusion equation that describes the sunspot ...
  • Effenberger, Frederic; Litvinenko, Yuri E. (Institute of Physics Publishing, 2014)
    The diffusion approximation to the Fokker-Planck equation is commonly used to model the transport of solar energetic particles in interplanetary space. In this study, we present exact analytical predictions of a higher ...
  • Craig, Ian J.D.; Effenberger, Frederic (IOP PUBLISHING LTD, 2014)
    The open problem of how singular current structures form in line-tied, three-dimensional magnetic fields is addressed. A Lagrangian magneto-frictional relaxation method is employed to model the field evolution toward the ...
  • Britz, Thomas; Cavenagh, Nicholas J.; Sørensen, Henrik Kragh (Electronic Journal of Combinatorics, 2015)
    We prove that each maximal partial Latin cube must have more than 29.289% of its cells filled and show by construction that this is a nearly tight bound. We also prove upper and lower bounds on the number of cells containing ...
  • Delbourgo, Daniel; Peters, Lloyd (Cambridge University Press, 2015)
    For the (d+1)-dimensional Lie group G=Z×pZp⊕d we determine through the use of p-power congruences a necessary and sufficient set of conditions whereby a collection of abelian L-functions arises from an element in K₁Zp[G]. ...
  • Cavenagh, Nicholas J. (Electronic Journal of Combinatorics, 2015)
    Let G be an even bipartite graph with partite sets X and Y such that |Y | is even and the minimum degree of a vertex in Y is at least 95|X|/96. Suppose furthermore that the number of edges in G is divisible by 4. Then G ...
  • Van Rijn, Jan N.; Holmes, Geoffrey; Pfahringer, Bernhard; Vanschoren, Joaquin (CEUR-WS, 2014)
    Modern society produces vast streams of data. Many stream mining algorithms have been developed to capture general trends in these streams, and make predictions for future observations, but relatively little is known about ...
  • Akram, Raja Naeem; Ko, Ryan K.L. (Institute of Electrical and Electronics Engineers Inc., 2015)
    One of the most crucial components of modern Information Technology (IT) systems is data. It can be argued that the majority of IT systems are built to collect, store, modify, communicate and use data, enabling different ...
  • Akram, Raja Naeem; Ko, Ryan K.L. (IEEE Computer Society, 2015)
    Along with the invention of computers and interconnected networks, physical societal notions like security, trust, and privacy entered the digital environment. The concept of digital environments begins with the trust ...
  • Akram, Raja Naeem; Ko, Ryan K.L.; Law, Tsz Fung (IEEE Computer Society, 2014)
    Online Social Networks (OSNs) are a unique construct that is shaped by the advancement and availability of Internet technologies. A large portion of internet users make use of OSN services to share and celebrate their ...
