      Ye, J.C.; Bouman, C.A.; Millane, R.P.; Webb, K.J. (University of Canterbury. Electrical and Computer Engineering, 1999)
      Optical diffusion tomography attempts to reconstruct an object cross section from measurements of scattered and attenuated light. While Bayesian approaches are well suited to this difficult nonlinear inverse problem, the ...
    • Nonlinear Phenomena in Coupled Cantilever Arrays 

      Gutschmidt S; Jackson S (2017)
      Cantilever arrays offer a promising alternative to standard single cantilever atomic force microscopy (AFM) imaging techniques. The successful implementation and operation of such an AFM array, however, is determined by ...
    • Nonlinear Regression Based Health Monitoring of Hysteretic Structures under Seismic Excitation 

      Xu, C.; Chase, J.G.; Rodgers, G.W. (University of Canterbury. Mechanical Engineering, 2015)
      This paper presents a health monitoring method using measured hysteretic responses. Acceleration and infrequently measured displacement are integrated using a multirate Kalman filtering method to generate restoring ...
    • The nonlinear seismic response of tall shear wall structures 

      Taylor, Roy George (University of Canterbury. Civil Engineering, 1977)
      New building codes are tending to place considerable value on the use of deterministic dynamic analyses as a means of assessing the ability of engineering structures to withstand severe seismic ground motions. An investigation ...
    • Nonlinear wave groups in deep water 

      Bryant, Peter John (University of Canterbury. Dept. of Mathematics, 1978)
      Nonlinear wave groups in deep water consist of wave modes for which nonlinear interactions and dispersion are in balance. The evolution equations for the wave modes are derived, and properties of nonlinear wave groups ...

    • Nonlinear-dispersive GaAs FET drain-current model for harmonic balance simulation 

      Eccleston, K.W. (University of Canterbury. Electrical and Computer Engineering, 1997)
      Popular GaAs FET large-signal drain conduction current models depend only on instantaneous terminal voltages, and ignore important phenomena that result in low frequency dispersion. To be valid at microwave frequencies, ...
    • Nonparametric Identification of the Distribution of Random Coefficients in Binary Response Static Games of Complete Information 

      Dunker F; Hoderlein S; Kaido H; Sherman R (2018)
      This paper studies binary response static games of complete information allowing complex heterogeneity through a random coefficients specification. The main result of the paper establishes nonparametric point identification ...
    • Nonrecursive digital image restoration 

      McDonnell, M. J. (University of Canterbury, 1975)
      The problem of digitally restoring blurred images is considered. The subject of image restoration is reviewed in detail and a comprehensive notation for image restoration is developed. Degraded images are divided into ...
    • Normalization of a Fading Channel 

      Mammela, A.; Hoyhtya, M.; Taylor, D.P. (University of Canterbury. Electrical and Computer Engineering, 2006)
      In this paper we discuss the proper normalization of a fading channel model. Physically, radio channels correspond to passive circuits and follow the energy conservation law. The ratio of the received energy to the ...
    • Normalized Cross-Correlation Method For Motion Imaging Of Human Skin 

      Hii, A.; Chase, J.G.; Hann, C.E.; Van Houten, E.E.W. (University of Canterbury. Mechanical Engineering., 2004)
      A major component of a Digital Image based Elasto-Tomography (DIET) breast cancer screening system is an accurate evaluation of skin tissue motion at the breast surface due to harmonic excitation. A motion tracking technique ...
    • Normalized naive set theory. 

      Istre, Erik (University of Canterbury, 2017)
      The broad goal of this thesis is the realization of a mathematically useful formal theory that contains a truth predicate, or as it's called in the literature, a "naive theory". To realize this goal, we explore the ...
    • NORMIT, a Web-enabled tutor for database normalization 

      Mitrovic, A. (University of Canterbury. Computer Science and Software Engineering., 2002)

    • A Notation for Expressing Restricting Conditions on a Context-Free Grammar 

      Lines, S. A. (University of Canterbury. Computer Science, 1977)
      Context-Free grammars have several features which make them suitable for defining programming languages. For instance, such grammars are: “recursive, have relatively simple and well understood recognizers, and a readable ...
    • Note on the hybridization number and subtree distance in phylogenetics 

      Humphries, P.J.; Semple, C. (University of Canterbury. Mathematics and Statistics, 2009)
      For two rooted phylogenetic trees T and T', the rooted subtree prune and regraft distance between T and T' has often been used as a replacement for the hybridization number of T and T'. However, Baroni et al. [M. Baroni, ...
