  • Heinzle, J. Mark; Uggla, Claes; Lim, Woei (American Physical Society, 2012)
    According to Belinskii., Khalatnikov and Lifshitz (BKL), a generic spacelike singularity is characterized by asymptotic locality: Asymptotically, toward the singularity, each spatial point evolves independently from its ...
  • Ting, Kai Ming; Witten, Ian H. (1997)
    Stacked generalization is a general method of using a high-level model to combine lower-level models to achieve greater predictive accuracy. In this paper we resolve two crucial issues which have been considered to be a ...
  • Ting, Kai Ming; Witten, Ian H. (1997)
    In this paper, we investigate the method of stacked generalization in combining models derived from different subsets of a training dataset by a single learning algorithm, as well as different algorithms. The simplest way ...
  • Sneyd, Alfred D.; Etay, J.; Fautrelle, Y. (2003)
    The present paper analyses the free surface deformation of a liquid metal drop under the influence of an alternating magnetic field. The analysis is restricted to the first axi- symmetric mode oscillation. In the low ...
  • Reeves, Steve; Streader, David (2006)
    In this paper we give simple example abstract data types, with atomic operations, that are related by data refinement under a definition used widely in the literature, but these abstract data types are not related by ...
  • Reeves, Steve; Streader, David (2003)
    State-based and process-based formalisms each come with their own distinct set of assumptions and properties. To combine them in a useful way it is important to be sure of these assumptions in order that the formalisms are ...
  • Jansen, Samuel Thomas; McGregor, Anthony James (John Wiley & Sons, Ltd., 2007)
    Many existing systems are written in C and are not re-entrant or thread safe. Sometimes these systems are required in a context for which they were not first designed, possibly meaning they now need to be re-entrant. This ...
  • Stokes, Tim E.; Hocking, Graeme Charles; Forbes, Lawrence K. (Cambridge University Press, 2012)
    The steady axisymmetric flow induced by a ring sink (or source) submerged in an unbounded inviscid fluid is computed and the resulting deformation of the free surface is obtained. Solutions are obtained analytically in the ...
  • Reeves, Steve; Streader, David (2005)
    Industry is looking to create a market in reliable "plug-and-play" components. To model components in a modular style it would be useful to combine event-based and state-based reasoning. One of the first steps in building ...
  • Witten, Ian H.; Bainbridge, David; Tansley, Robert; Huang, Chi-Yu; Don, Katherine J. (University of Waikato, Department of Computer Science, 2005)
    Greenstone and DSpace are widely-used software systems for digital libraries, and prospective users sometimes wonder which one to adopt. In fact, the aims of the two are very different, although their domains of application ...
  • Bönström, Valerie; Hinze, Annika; Schweppe, Heinz (IEEE Computer Society, Washington, DC, USA, 2003)
    RDF is the first W3C standard for enriching information resources of the Web with detailed meta data. The semantics of RDF data is defined using a RDF schema. The most expressive language for querying RDF is RQL, which ...
  • Barbour, Robert H.; Yeo, Alvin (1997)
    Many software companies today are developing software not only for local consumption but for the rest of the world. We introduce the concepts of internationalisation and localisation and discuss some techniques using these ...
  • Holmes, Geoffrey; Kirkby, Richard Brendon; Pfahringer, Bernhard (Springer, Berlin, 2005)
    Hoeffding trees are state-of-the-art in classification for data streams. They perform prediction by choosing the majority class at each leaf. Their predictive accuracy can be increased by adding Naive Bayes models at the ...
  • Bainbridge, David; Witten, Ian H.; Boddie, Stefan J.; Thompson, John (Springer, 2009)
    DSpace, Fedora, and Greenstone are three widely used open source digital library systems. In this paper we report on scalability tests performed on these tools by ourselves and others. These range from repositories populated ...
  • Kalnins, Ernie G.; Miller, W., Jr. (the Department of Applied Research, Institute of Mathematics of National Academy of Sciences of Ukraine, 2012)
    The classical Kepler-Coulomb system in 3 dimensions is well known to be 2nd order superintegrable, with a symmetry algebra that closes polynomially under Poisson brackets. This polynomial closure is typical for 2nd order ...
  • Kalnins, Ernie G.; Kress, Jonathan M.; Miller, W., Jr.; Post, Sarah (2009)
    The structure theory for the quadratic algebra generated by first and second order constants of the motion for 2D second order superintegrable systems with nondegenerate (3-parameter) and or 2-parameter potentials is well ...
  • Bainbridge, David; Downie, J. Stephen; Ehmann, Andreas F. (ACM, 2012)
    This work illustrates how audio content analysis of music and manually assigned structural temporal metadata can be used to form a digital library designed for musicological exploration. In addition to text-based searching ...
  • Zimek, Arthur; Buchwald, Fabian; Frank, Eibe; Kramer, Stefan (2008)
    Automatic classification of proteins using machine learning is an important problem that has received significant attention in the literature. One feature of this problem is that expert-defined hierarchies of protein classes ...
  • Medelyan, Olena; Perrone, Vye; Witten, Ian H. (ACM, 2010)
    Selecting subject headings and keywords is a chore for all metadata editors, who often leave these fields blank or incomplete—even when there are no guidelines and any word or phrase can be chosen. For example, tags are ...
  • Bittner, Sven; Hinze, Annika (2006)
    A main challenge in distributed publish/subscribe systems is the efficient and scalable routing of incoming information (event messages). For largescale publish/subscribe services, subscription forwarding has been established ...
