  • The classification of partition homogeneous groups with applications to semigroup theory 

    André, Jorge; Araúo, Joāo; Cameron, Peter Jephson (2016-04-15) - Journal article
    Let λ=(λ1,λ2,...) be a partition of n, a sequence of positive integers in non-increasing order with sum n. Let Ω:={1,...,n}. An ordered partition P=(A1,A2,...) of Ω has type λ if |Ai|=λi.Following Martin and Sagan, we say ...
  • Codimension formulae for the intersection of fractal subsets of Cantor spaces 

    Donoven, Casey; Falconer, Kenneth John (2016-02) - Journal article
    We examine the dimensions of the intersection of a subset E of an m-ary Cantor space Cm with the image of a subset F under a random isometry with respect to a natural metric. We obtain almost sure upper bounds for the ...
  • A combined theory for magnetohydrodynamic equilibria with anisotropic pressure and magnetic shear 

    Hodgson, Jonathan David Brockie; Neukirch, Thomas (2017-03-10) - Journal article
    We present a new approach to the theory of magnetohydrodynamic equilibria with anisotropic pressure, magnetic shear and translational/rotational invariance. This approach involves combining two existing formalisms in order ...
  • Comparing pre- and post-construction distributions of long-tailed ducks Clangula hyemalis in and around the Nysted offshore wind farm, Denmark : a quasi-designed experiment accounting for imperfect detection, local surface features and autocorrelation 

    Petersen, Ib Krag; MacKenzie, Monique Lea; Rexstad, Eric; Wisz, Mary S.; Fox, Anthony D. (University of St Andrews, 2011) - Report
    We report a novel technique to model abundance patterns of wintering seaducks in relation to the construction of an offshore wind farm (OWF) based on seven years of aerial survey transect data. Distance sampling was used ...
  • Comparison of aerial survey methods for estimating abundance of common scoters 

    Rexstad, Eric; Buckland, Stephen T. (CREEM, University of St Andrews, 2009) - Report
    During the month of March, four survey methods were applied to the SPA at Camarthen Bay. WWT staff carried out visual aerial surveys using distance sampling methodology (Camphuysen et al. 2004). Visual shore-based counts ...
  • Comparison of variational balance models for the rotating shallow water equations 

    Dritschel, David Gerard; Gottwald, Georg; Oliver, Marcel (2017-07) - Journal article
    We present an extensive numerical comparison of a family of balance models appropriate to the semi-geostrophic limit of the rotating shallow water equations, and derived by variational asymptotics in Oliver (J. Fluid Mech., ...
  • Complex Region Spatial Smoother (CReSS) 

    Scott Hayward, Lindesay Alexandra Sarah; MacKenzie, Monique Lea; Donovan, Carl Robert; Walker, Cameron; Ashe, Erin (University of St Andrews, 2011) - Report
    Conventional smoothing over complicated coastal and island regions may result in errors across boundaries, due to the use of Euclidean distances to represent inter-point similarity. The new Complex Region Spatial Smoother ...
  • Compressed dynamic mode decomposition for background modeling 

    Erichson, N. Benjamin; Brunton, Steven L.; Kutz, J. Nathan (2016-11-29) - Journal article
    We introduce the method of compressed dynamic mode decomposition (cDMD) for background modeling. The dynamic mode decomposition is a regression technique that integrates two of the leading data analysis methods in use ...
  • A computational framework for particle and whole cell tracking applied to a real biological dataset 

    Yang, Feng Wei; Venkataraman, Chandrasekhar; Styles, Vanessa; Kuttenberger, Verena; Horn, Elias; von Guttenberg, Zeno; Madzvamuse, Anotida (2016-05-24) - Journal article
    Cell tracking is becoming increasingly important in cell biology as it provides a valuable tool for analysing experimental data and hence furthering our understanding of dynamic cellular phenomena. The advent of high-throughput, ...
  • Computing finite semigroups 

    East, J.; Egri-Nagy, A.; Mitchell, J. D.; Péresse, Y. (2015-10-07) - Journal article
    Using a variant of Schreier's Theorem, and the theory of Green's relations, we show how to reduce the computation of an arbitrary subsemigroup of a finite regular semigroup to that of certain associated subgroups. Examples ...
  • conting : an R package for Bayesian analysis of complete and incomplete contingency tables 

    Overstall, Antony; King, Ruth (2014-06) - Journal article
    The aim of this paper is to demonstrate the R package conting for the Bayesian analysis of complete and incomplete contingency tables using hierarchical log-linear models. This package allows a user to identify interactions ...
  • Convectively induced shear instability in large amplitude internal solitary waves 

    Carr, Magda; Fructus, D; Grue, J; Jensen, A; Davies, P A (2008-12) - Journal article
    Laboratory study has been carried out to investigate the instability of an internal solitary wave of depression in a shallow stratified fluid system. The experimental campaign has been supported by theoretical computations ...
  • A conversation with Richard M. Cormack 

    Buckland, Stephen Terrence (2016-05) - Journal article
    Richard Melville Cormack is one of the giants who developed the theory of mark-recapture. Referring to his key paper in 1964, and the papers published back-to-back in 1965 by George Jolly and George Seber, the `Cormack-Jolly-Seber ...
  • Coprime invariable generation and minimal-exponent groups 

    Detomi, Eloisa; Lucchini, Andrea; Roney-Dougal, C.M. (2015-08) - Journal article
    A finite group G is coprimely invariably generated if there exists a set of generators {g1,. .,gu} of G with the property that the orders |g1|,. .,|gu| are pairwise coprime and that for all x1,. .,xu∈G the set {g1x1,. ...
  • Copulae on products of compact Riemannian manifolds 

    Jupp, P.E. (2015-09) - Journal article
    Abstract One standard way of considering a probability distribution on the unit n -cube, [0 , 1]n , due to Sklar (1959), is to decompose it into its marginal distributions and a copula, i.e. a probability distribution on ...
  • Counting chirps : acoustic monitoring of cryptic frogs 

    Measey, G. John; Stevenson, Ben C.; Scott, Tanya; Altwegg, Res; Borchers, David L. (2017-06) - Journal article
    1 .  Global amphibian declines have resulted in a vital need for monitoring programmes that follow population trends. Monitoring using advertisement calls is ideal as choruses are undisturbed during data collection. However, ...
  • Coupled bulk-surface free boundary problems arising from a mathematical model of receptor-ligand dynamics 

    Elliot, Charles M.; Ranner, Thomas; Venkataraman, Chandrasekhar (2017-02-08) - Journal article
