Assessing the significance of changes in ENSO amplitude using variance metrics
(American Meteorological Society, 20140101)The variance of time series records relating to ENSO, such as the interannual anomalies or bandpass filtered components of equatorial Pacific SST indices, provides one approach to quantifying changes in ENSO amplitude. ... 
Assessment and optimisation of STCA performance: Using the Pareto optimal receiver operating characteristic
(2008)Short Term Conflict Alert (STCA) systems are complex software programs, with many parameters that must be adjusted to achieve best performance. We describe a simple evolutionary algorithm for optimising the tradeoff between ... 
Assessment of entanglement risk to marine megafauna due to offshore renewable energy mooring systems
(Elsevier, 201509)This paper defines a methodology to compare different offshore renewable energy (ORE) mooring configurations in terms of the risk of entanglement they present to marine megafauna. Currently, the entanglement of large marine ... 
Assessment of Highway Bridge Upgrading by Dynamic Testing and FiniteElement Model Updating
(American Society of Civil Engineers, 20030415)The Land Transport Authority of Singapore has a continuing program of highway bridge upgrading, to refurbish and strengthen bridges to allow for increasing vehicle traffic and increasing axle loads. One subject of this ... 
Application of Box–Jenkins models for assessing the effect of unusual events recorded by structural health monitoring systems
(Sage, 200210)Inservice civil infrastructure experience shortlived and transient changes in strain from time to time resulting for example from ground movements, development of cracks, heavy traffic, and accidents. With the advent of ... 
Assessment of the effectiveness and economic efficiency of selected support options for the United Kingdom
(University of Exeter, 201104)This Working Document summarises the results of the assessment of the effectiveness and economic efficiency of different support instrument options to foster the market penetration of RESH/C in the UK. For two selected ... 
Assessment of the effectiveness of a riskreduction measure on pluvial flooding and economic loss in Eindhoven, the Netherlands
(Elsevier, 2014)Cities are increasingly assessing and reducing pluvial flood risk. Quantitative assessment of the effectiveness of riskreduction measures is required. We use hydraulic simulation with GISbased financial analysis to assess ... 
Astronomical constraints on the duration of the Early JurassicPliensbachianStage and global climatic fluctuations
(Elsevier, 20161005)The Early Jurassic was marked by multiple periods of major global climatic and palaeoceanographic change, biotic turnover and perturbed global geochemical cycles, commonly linked to large igneous province volcanism. This ... 
Asymmetric dot dimers – optical properties and interactions
(20150106)We present a study of the rich optical behaviour of the dark (grey) modes exhibited by asymmetric dot dimers and how this behaviour is modified upon interaction between dimers. 
Asymmetry of magnetosheath flows and magnetopause shape during low Alfven Mach number solar wind
(American Geophysical Union (AGU), 2013)Previous works have emphasized the significant influence of the solar wind Alfvén Mach number (MA) on magnetospheric dynamics. Here we report statistical, observational results that pertain to changes in the magnetosheath ... 
Asymmetry of spin wave dispersions in a hexagonal magnonic crystal
(American Institute of Physics (AIP), 20130524)We report a study of the dispersion of spin waves in a hexagonal array of interacting ferromagnetic nanodisks for two orthogonal orientations of the inplane applied magnetic field, i.e., either parallel or perpendicular ... 
Asymptotic analysis and analytical solutions of a model of cardiac excitation.
(Springer Verlag, 2008)We describe an asymptotic approach to gated ionic models of singlecell cardiac excitability. It has a form essentially different from the Tikhonov fastslow form assumed in standard asymptotic reductions of excitable ... 
Asymptotic and numerical solutions of the initial value problem in rotating planetary fluid cores
(Oxford University Press / Royal Astronomical Society, 2010)An initial state of fluid motion in planetary cores or atmospheres, excited, for example, by the giant impact of an asteroid or an earthquake and then damped by viscous dissipation, decays towards the state of rigidbody ... 
An asymptotic parallelintime method for highly oscillatory PDEs
(Society for Industrial and Applied Mathematics, 20130326)We present a new timestepping algorithm for nonlinear PDEs that exhibit scale separation in time. Our scheme combines asymptotic techniques (which are inexpensive but can have insufficient accuracy) with parallelintime ... 
Asymptotic properties of mathematical models of excitability.
(Royal Society, 2006)We analyse small parameters in selected models of biological excitability, including HodgkinHuxley (Hodgkin & Huxley 1952 J. Physiol.117, 500544) model of nerve axon, Noble (Noble 1962 J. Physiol.160, 317352) model of ... 
Asymptotic theory for torsional convection in rotating fluid spheres
(Cambridge University Press, 20170119)This paper is concerned with the classical, wellstudied problem of convective instabilities in rapidly rotating, selfgravitating, internally heated Boussinesq fluid spheres. Sanchez et al. (J. Fluid Mech., vol. 791, 2016, ... 
Asymptotic theory of resonant flow in a spheroidal cavity driven by latitudinal libration
(Cambridge University Press, 2012) 
Asymptotics of conduction velocity restitution in models of electrical excitation in the heart.
(Springer Verlag, 2011)We extend a nonTikhonov asymptotic embedding, proposed earlier, for calculation of conduction velocity restitution curves in ionic models of cardiac excitability. Conduction velocity restitution is the simplest nontrivial ... 
Asynchronous Networks and Event Driven Dynamics
(IOP Publishing, 20170106)Realworld networks in technology, engineering and biology often exhibit dynamics that cannot be adequately reproduced using network models given by smooth dynamical systems and a fixed network topology. Asynchronous ... 
Asynchronous Networks: Modularization of Dynamics Theorem
(IOP Publishing, 20170106)Building on the first part of this paper, we develop the theory of functional asynchronous networks. We show that a large class of functional asynchronous networks can be (uniquely) represented as feedforward networks ...
