Alternating Direction Implicit (ADI) schemes for a PDE-based image osmosis model
(Journal of Physics: Conference Series, 2017-10-22)© Published under licence by IOP Publishing Ltd. We consider Alternating Direction Implicit (ADI) splitting schemes to compute efficiently the numerical solution of the PDE osmosis model considered by Weickert et al. in ...

An Alternative to Using the 3D Delaunay Tessellation for Representing Freespace
(1989-09-01)Representing the world in terms of visible surfaces and the freespacesexisting between these surfaces and the viewer is an important problemsin robotics. Recently, researchers have proposed using the 3DsDelaunay ...

AMAR: A Computational Model of Autosegmental Phonology
(1993-10-01)This report describes a computational system with which phonologists may describe a natural language in terms of autosegmental phonology, currently the most advanced theory pertaining to the sound systems of human ...

Ambiguities of a Motion Field
(1987-01-01)We study the conditions under which a perspective motion field can have multiple interpretations. Furthermore, we show that in most cases, the ambiguity in the interpretation of a motion field can be resolved by imposing ...

AMORD: A Deductive Procedure System
(1978-01-01)We have implemented an interpreter for a rule-based system, AMORD, based on a non-chronological control structure and a system of automatically maintained data-dependencies. The purpose of this paper is to serve as a ...

Amorphous Infrastructure for Language Implementation
(2002-12-10)We propose a method for the robust implementation of simple graphical automataon an amorphous computer. This infrastructure is applied to the implementationof purely functional programming languages. Specifically, it is ...

Amorphous Medium Language
(2005-07)Programming reliable behavior on a large mesh network composed of unreliable parts is difficult. Amorphous Medium Language addresses this problem by abstracting robustness and networking issues away from the programmer via ...

Ample subvarieties and q-ample divisors
(ElsevierAdvances in Mathematics, 2012-03-20)We introduce a notion of ampleness for subschemes of any codimension using the theory of q-ample line bundles. We also investigate certain geometric properties satisfied by ample subvarieties, e.g. the Lefschetz ...

An a$_{0}$ resonance in strongly coupled πη, K$\bar K$ scattering from lattice QCD
(American Physical SocietyPhysical Review D, 2016-05-11)We present the first calculation of coupled-channel meson-meson scattering in the isospin =1, G-parity negative sector, with channels πη, K$\bar K$ and πη′, in a first-principles approach to QCD. From the discrete spectrum ...

An Algorithm for Deciding BAPA: Boolean Algebra with Presburger Arithmetic
(2004-07-19)We describe an algorithm for deciding the first-order multisorted theory BAPA, which combines 1) Boolean algebras of sets of uninterpreted elements (BA) and 2) Presburger arithmetic operations (PA). BAPA can express the ...

An Analysis of Posynomial MOSFET Models Using Genetic Algorithms and Visualization
(2007-06-05)Analog designers are interested in optimization tools which automate the process of circuit sizing. Geometric programming, which uses posynomial models of MOSFET parameters, represents one such tool. Genetic algorithms ...

An Analytic Solution for Gust-Aerofoil Interaction Noise Including Effects of Geometry
(Oxford University PressIMA Journal of Applied Mathematics, 2016)An analytic solution is obtained for the sound generated by gust-aerofoil interaction for aerofoils with thickness, camber, and angle of attack. The model is based on the linearisation of the Euler equations about a steady ...

An analytically-based method for predicting the noise generated by the interaction between turbulence and a serrated leading edge
(ElsevierJournal of Sound and Vibration, 2018-05-26)This paper considers the interaction of turbulence with a serrated leading edge. We investigate the noise produced by an aerofoil moving through a turbulent perturbation to uniform flow by considering the scattered pressure ...

An empirical analysis of subprime consumer credit demand
(2010)We test the interest rate sensitivity of subprime credit card borrowers using a unique panel data set from a UK credit card company. What is novel about our contribution is that we were given details of a randomized interest ...
