The method of fundamental solutions for heat conduction in layered materials
(1999)In this paper, we investigate the application of the Method of Fundamental Solutions (MFS) to twodimensional problems of steadystate heat conduction in isotropic and anisotropic bimaterials. Two approaches are used: a ...

The method of fundamental solutions for threedimensional inverse geometric elasticity problems
(2016)We investigate the numerical reconstruction of smooth starshaped voids (rigid inclusions and cavities) which are compactly contained in a threedimensional isotropic linear elastic medium from a single set of Cauchy data ...

Modeling of the selfpropagating reactions of nickel and aluminum multilayered foils
(2009)In this study, we performed simulations of selfpropagating reactions of nanoscale nickelaluminum multilayers using numerical methods. The model employs twodimensional heat transfer equations coupled with heat generation ...

Note on the distribution of extreme wave crests
(2005)The sea elevation at a fixed point is modelled by means of a second order model, which is a smooth algebraic function of a vector valued Gaussian process. Asymptotic methods, presented first in [1], are used to estimate ...

A numerical conformal mapping method for harmonic mixed boundary value problems
(1996)We describe a simple and versatile technique for the numerical solution of harmonic mixed boundary value problems in simplyconnected domains. This technique is based on the theory of RiemannHilbert problems, and involves ...

Numerical investigation of the nonlinear heat diffusion equation with high nonlinearity on the boundary
(2008)A nonlinear heat diffusion problem is considered when the thermal conductivity and heat capacity are nonlinear functions of the temperature. At one of the boundaries a highly nonlinear condition is imposed involving both ...

Numerical modeling and experimental studies of light pulse propagation in inhomogeneous random media
(Publ by Society of PhotoOptical Instrumentation Engineers, 1993)The effects of discrete absorbing and scattering objects on light propagation characteristics in random media were examined. Light propagation in the inhomogeneous medium was modeled using a finite difference representation ...

Numerical similarity reductions of the (1+3)dimensional Burgers equation
(2011)We consider the (1+3)dimensional Burgers equation ut = u xx + uyy + uzz + uux which has considerable interest in mathematical physics. Lie symmetries are used to reduce it to certain ordinary differential equations. We ...

A numerical study of the SVDMFS solution of inverse boundary value problems in twodimensional steadystate linear thermoelasticity
(2015)We study the reconstruction of the missing thermal and mechanical data on an inaccessible part of the boundary in the case of twodimensional linear isotropic thermoelastic materials from overprescribed noisy measurements ...

On the classification of similarity solutions of a twodimensional diffusionadvection equation
(2007)We consider the twodimensional diffusionadvection equation ut = Duyy  frac(d k, d u) ux. We present the classification of Lie symmetries of this equation. For the case k(u) = u2 we give the complete list of similarity ...

Portable parallel implementation of two novel mathematical biology algorithms in ZPL
(ACM, 1995)This paper shows that mathematical models of biological pattern formation are ideally suited to data parallelism. We present two new algorithms, one for simulating the dynamic structure of fibroblasts, and the other for ...

Article
Potential field based geometric modelling using the method of fundamental solutions
(2006)We propose a new geometric modelling method based on the socalled potential field (PF) modelling technique. The harmonic problem associated with this technique is solved numerically using the method of fundamental solutions ...

Processing of semisolid materials using a shearthickening Bingham fluid model
(Publ by ASME, 1994)Recently the importance of processing metals and metal matrix composites in semisolid state is growing rapidly. Performing the shape making operations in the semisolid state provides a better opportunity to control the ...

Rapid shear of initially anisotropic turbulence in a rotating frame?
(2007)In the present study, we investigate, using inviscid rapid distortion theory, the evolution of sheared turbulence in a rotating frame as a function of the rotation rate (including stable, transitional, and unstable regimes), ...

Renormalization and mixing in lattice QCD: The case of the chromomagnetic operator
(2014)We study matrix elements of the "chromomagnetic" operator on the lattice. This operator is contained in the strangenesschanging effective Hamiltonian which describes electroweak effects in the Standard Model and beyond. ...

Robust coding for uncertain sources: A minimax approach
(2005)This paper is concerned with designing minimum average length uniquely decodable codes, for a family of source distributions for which the relative entropy with respect to a given nominal distribution is bounded above by ...

A singular function boundary integral method for the laplace equation
(1996)The authors present a new singular function boundary integral method for the numerical solution of problems with singularities which is based on approximation of the solution by the leading terms of the local asymptotic ...
