  • Emslie, A. Gordon; Holman, Gordon D.; Litvinenko, Yuri E. (Institute of Physics Publishing, 2014)
    Electrons accelerated in solar flares are injected into the surrounding plasma, where they are subjected to the influence of collisional (Coulomb) energy losses. Their evolution is modeled by a partial differential equation ...
  • Durrant, Robert J.; Kabán, Ata (Springer Verlag, 2014)
    We prove theoretical guarantees for an averaging-ensemble of randomly projected Fisher linear discriminant classifiers, focusing on the casewhen there are fewer training observations than data dimensions. The specific form ...
  • Matthaeus, William H.; Oughton, Sean; Osman, Kareem T.; Servidio, Sergio; Wan, Minping; Gary, SP; Shay, MA; Valentini, F; Roytershteyn, V; Karimabadi, H; Chapman, SC (American Astronomical Society, 2014)
    The application of linear kinetic treatments to plasma waves, damping, and instability requires favorable inequalities between the associated linear timescales and timescales for nonlinear (e.g., turbulence) evolution. In ...
  • Jung, Yoonsuh; Huang, Jianhua; Hu, Jianhua (Taylor & Francis, 2014)
    In genome-wide association studies, the primary task is to detect biomarkers in the form of Single Nucleotide Polymorphisms (SNPs) that have nontrivial associations with a disease phenotype and some other important ...
  • Mayo, Michael; Sun, Quan (IEEE, 2014)
    Differential Evolution can be used to construct effective and compact artificial training datasets for machine learning algorithms. In this paper, a series of comparative experiments are performed in which two simple ...
  • Cunningham, Sally Jo; Nichols, David M. (2014)
    As researchers retire or pass away, the online record of their work and their research careers begins to fragment and fade away. We begin with case studies of four New Zealand Humanities researchers, nearing or at the ends ...
  • Cunningham, Sally Jo; Nichols, David M.; Bainbridge, David; Ali, Hasan (ISMIR, 2014)
    This paper builds an understanding of how music is currently experienced by a social group travelling together in a car - how songs are chosen for playing, how music both reflects and influences the group’s mood and social ...
  • Litvinenko, Yuri E.; Effenberger, Frederic (The American Astronomical Society, 2014)
    Motivated by recent applications of superdiffusive transport models to shock-accelerated particle distributions in the heliosphere, we analytically solve a one-dimensional fractional diffusion-advection equation for the ...
  • Downie, J. Stephen; Hu, Xiao; Lee, Jin Ha; Choi, Kahyun; Cunningham, Sally Jo; Hao, Yun (ISMIR, 2014)
    The Music Information Retrieval Evaluation eXchange (MIREX) has been run annually since 2005, with the October 2014 plenary marking its tenth iteration. By 2013, MIREX has evaluated approximately 2000 individual music ...
  • Fichtner, Horst; Scherer, Klaus; Effenberger, Frederic; Zönnchen, Jochen; Schwadron, Nathan; McComas, David J. (2014)
    Context. A new hypothesis is offered to explain the so-called ribbon feature appearing in the all-sky flux maps of energetic neutral atoms presently observed with the IBEX spacecraft, namely that the ribbon is a consequence ...
  • Bowen, Judith Alyson; Cunningham, Sally Jo; Hinze, Annika; Jung, Doris; Reeves, Steve (Department of Computer Science, The University of Waikato, 2014)
    This position paper outlines our approach to improve the usage choice of suitable devices in different health care environments (contexts). Safety-critical medical devices are presumed to have undergone a thorough ...
  • Žliobaitė, Indrė; Bifet, Albert; Read, Jesse; Pfahringer, Bernhard; Holmes, Geoffrey (Springer, 2014)
    Predictive modeling on data streams plays an important role in modern data analysis, where data arrives continuously and needs to be mined in real time. In the stream setting the data distribution is often evolving over ...
  • Ko, Ryan K.L.; Will, Mark A. (IEEE, 2014)
    Cloud data provenance, or "what has happened to my data in the cloud", is a critical data security component which addresses pressing data accountability and data governance issues in cloud computing systems. In this paper, ...
  • Ko, Ryan K.L.; Tan, Alan Y.S.; Ng, Grace P.Y. (IEEE, 2014)
    The current pay-per-use model adopted by public cloud service providers has influenced the perception on how a cloud should provide its resources to end-users, i.e. on-demand and access to an unlimited amount of resources. ...
  • Mohajerani, Sahar; Malik, Robi; Fabian, Martin (IFAC, 2014)
    This paper describes an approach for compositional nonblocking verification of discrete event systems modelled as extended finite-state machines (EFSM). Previous results about finite-state machines in lock-step synchronisation ...
  • Tan, Alan Y.S.; Ko, Ryan K.L.; Mendiratta, Veena (IEEE, 2014)
    Knowing the number of virtual machines (VMs) that a cloud physical hardware can (further) support is critical as it has implications on provisioning and hardware procurement. However, current methods for estimating the ...
  • Ware, Simon; Malik, Robi; Mohajerani, Sahar; Fabian, Martin (Springer International Publishing, 2014)
    This paper proposes an abstraction method for compositional synthesis. Synthesis is a method to automatically compute a control program or supervisor that restricts the behaviour of a given system to ensure safety and ...
  • Fowke, Michael; Hinze, Annika; Heese, Ralf (University of Waikato, Department of Computer Science, 2013)
    This report covers the implementation of software that aims to identify document versions and se-mantically related documents. This is important due to the increasing amount of digital information. Key criteria were that ...
  • Fowke, Michael; Hinze, Annika; Heese, Ralf (University of Waikato, Department of Computer Science, 2013)
    Document classification and provenance has become an important area of computer science as the amount of digital information is growing significantly. Organisations are storing documents on computers rather than in paper ...
  • Fowke, Michael; Hinze, Annika; Heese, Ralf (University of Waikato, Department of Computer Science, 2013)
    This research looks at the most appropriate similarity measure to use for a document classification problem. The goal is to find a method that is accurate in finding both semantically and version related documents. A ...
