  • Maximum gradient dimensionality reduction

    Luo, Xianghui; Durrant, Robert J. (IEEE, 2018)
    We propose a novel dimensionality reduction approach based on the gradient of the regression function. Our approach is conceptually similar to Principal Component Analysis, however instead of seeking a low dimensional ...
  • Testing the promise of access to justice through online courts

    Toy-Cronin, Bridgette; Irvine, Bridget; Nichols, David M.; Cunningham, Sally Jo; Tkacukova, Tatiana (Boom Uitgevers Den Haag, 2018)
    Modernization is increasingly knocking on the courthouse door. Many common law countries are investigating ways to introduce technology to improve civil courts, including the introduction of online courts. These state-led ...
  • The use of Māori words in National Science Challenge online discourse

    Calude, Andreea S.; Stevenson, Louise; Whaanga, Hēmi; Keegan, Te Taka Adrian Gregory (Taylor & Francis, 2019)
    New Zealand English is well-known for its heavy borrowing of words from Māori. This lexical component, unique to New Zealand English alone has been studied intensely over the last 50 years, particularly in newspaper media. ...
  • Adoption of international privacy standards in New Zealand health information research.

    Yogarajan, Vithya; Ragupathy, Rajan (2019)
    The use of patient health information in secondary research (henceforth referred as health information research) has many potential health and economic benefits for New Zealand, but patient privacy must be protected in the ...
  • Chinese postgraduates' explanation of the sources of sentence initial bundles in their thesis writing

    Li, Liang; Franken, Margaret; Wu, Shaoqun (2018)
    Lexical bundles, recurrent multiword combinations in a register, are extremely common and important discourse building blocks in academic writing. An increasing number of studies have investigated lexical bundles in academic ...
  • Automatic end-to-end De-identification: Is high accuracy the only metric?

    Yogarajan, Vithya; Pfahringer, Bernhard; Mayo, Michael (2019)
    De-identification of electronic health records (EHR) is a vital step towards advancing health informatics research and maximising the use of available data. It is a two-step process where step one is the identification of ...
  • Finite dissipation in anisotropic magnetohydrodynamic turbulence

    Bandyopadhyay, R.; Oughton, Sean; Wan, M.; Matthaeus, William H.; Chhiber, R.; Parashar, Tulasi N. (American Physical Society, 2018)
    In the presence of an externally supported, mean magnetic field, a turbulent, conducting medium, such as plasma, becomes anisotropic. This mean magnetic field, which is separate from the fluctuating, turbulent part of the ...
  • Māori language procreation on social media

    Keegan, Te Taka Adrian Gregory (2019)
    The Māori language has taken seed and grown on social media. This presentation will examine this presence, exploring the forms it has taken and the influence it is having. It will look at Facebook groups devoted to the ...
  • Biosensing by Learning: Cancer Detection as Iterative optimization.

    Chen, Yifan; Sharifi, Neda; Holmes, Geoffrey; Cheang, U. Kei (IEEE, 2018)
    We propose a novel cancer detection procedure (CDP) based on an iterative optimization method. The global minimum of a tumor-induced biological cost function indicates the tumor location, the domain of the cost function ...
  • Modelling fractal-structured smart microgrids: Exploring signals and protocols

    Apperley, Mark (IARIA, 2019)
    This paper discusses some of the issues surrounding the interconnection of smart microgrids, with a focus on fractal structures, their implementation, management, operation, and potential effectiveness. It builds on a basic ...
  • Optimal task scheduling in a flexible manufacturing system using model checking

    Malik, Robi; Pena, Patricia N. (2018)
    This paper demonstrates the use of model checking to solve the problem of optimal task scheduling in a flexible manufacturing system. The system is modelled as a discrete event system, for which the least restrictive safe ...
  • Māori loanwords: a corpus of New Zealand English tweets

    Trye, David; Calude, Andreea S.; Bravo-Marquez, Felipe; Keegan, Te Taka Adrian Gregory (2019)
    Māori loanwords are widely used in New Zealand English for various social functions by New Zealanders within and outside of the Māori community. Motivated by the lack of linguistic resources for studying how Māori loanwords ...
  • Effectiveness of entropy-based features in high-and low-intensity DDoS attacks detection

    Koay, Abigail; Welch, Ian; Seah, Winston K.G. (Springer, 2019)
    DDoS attack detection using entropy-based features in network traffic has become a popular approach among researchers in the last five years. The use of traffic distribution features constructed using entropy measures has ...
  • Security visualization intelligence model for law enforcement investigations

    Garae, Jeffery; Ko, Ryan K.L.; Apperley, Mark; Schlickmann, Silvino J. (2018)
    Data analytic methods and techniques have proven crucial in aiding law enforcement investigations and day-to-day operations. However, the rise of cyber-attacks across transnational jurisdictions creates a challenge to share ...
  • Behaviour based ransomware detection

    Chew, Christopher J.W.; Kumar, Vimal (EasyChair, 2019)
    Ransomware is an ever-increasing threat in the world of cyber security targeting vulnerable users and companies, but what is lacking is an easier way to group, and devise practical and easy solutions which every day users ...
  • Identifying the interplay of design artifacts and decisions in practice: A Case Study

    Bowen, Judy; Dittmar, Anke (Springer, 2017)
    Interaction design is a complex and challenging process. It encompasses skills and knowledge from design in general as well as from HCI and software design in particular. In order to find better ways to support interaction ...
  • Investigating Wearable Technology for Fatigue Identification in the Workplace

    Griffiths, Christopher John Gilder; Bowen, Judy; Hinze, Annika (Springer, 2017)
    Fatigue has been identified as a significant contributor to workplace accident rates. However, risk minimisation is a process largely based on self-reporting methodologies, which are not suitable for fatigue identification ...
  • Using abstraction with interaction sequences for interactive system modelling

    Turner, Jessica; Bowen, Judy; Reeves, Steve (Springer, 2018)
    Interaction sequences can be used as an abstraction of an interactive system. We can use such models to consider or verify properties of a system for testing purposes. However, interaction sequences have the potential to ...
