  • 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 ...
  • 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. (2016-12-01) - 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
    We consider a coupled bulk-surface system of partial differential equations with nonlinear coupling modelling receptor-ligand dynamics. The model arises as a simplification of a mathematical model for the reaction between ...
  • The critical merger distance between two co-rotating quasi-geostrophic vortices 

    Reinaud, Jean Noel; Dritschel, David Gerard (2005-01-10) - Journal article
    This paper examines the critical merger or strong interaction distance between two equal-potential-vorticity quasi-geostrophic vortices. The interaction between the two vortices depends on five parameters: their volume ...
  • A critical review of the literature on population modelling 

    Cabrelli, Abigail; Harwood, John; Matthiopoulos, Jason; New, Leslie Frances; Thomas, Len (University of St Andrews, 2009) - Report
    The 2005 report of the National Research Council’s ‘Committee on Characterizing Biologically Significant Marine Mammal Behavior’ proposed a framework, which they called PCAD - Population Consequences of Acoustic Disturbance, ...
  • Decomposition tables for experiments : I. A chain of randomizations 

    Brien, C. J.; Bailey, Rosemary Anne (2009-12) - Journal article
    One aspect of evaluating the design for an experiment is the discovery of the relationships between subspaces of the data space. Initially we establish the notation and methods for evaluating an experiment with a single ...
  • Decomposition tables for experiments : II. Two–one randomizations 

    Brien, C. J.; Bailey, Rosemary Anne (2010-10) - Journal article
    We investigate structure for pairs of randomizations that do not follow each other in a chain. These are unrandomized-inclusive, independent, coincident or double randomizations. This involves taking several structures ...
  • A default prior distribution for contingency tables with dependent factor levels 

    Overstall, Antony; King, Ruth (2014-01) - Journal article
    A default prior distribution is proposed for the Bayesian analysis of contingency tables. The prior is specified to allow for dependence between levels of the factors. Different dependence structures are considered, including ...

    Ritchie, M. L.; Wilmot-Smith, A. L.; Hornig, G. (2016-06-06) - Journal article
    The Parker hypothesis assumes that heating of coronal loops occurs due to reconnection, induced when photospheric motions braid field lines to the point of current sheet formation. In this contribution we address the ...
