Mathematics of Computation, Vol. 79, No. 271 (JULY 2010), pp. 1263-1301 (39 pages) This article studies the numerical approximation of harmonic maps into surfaces, i.e., critical points for the ...

Abstract. Numerical approximations to the solution of a linear singularly perturbed parabolic convection-diffusion problem are generated using a backward Euler method in time and an upwinded finite ...

It is now possible to improve the precision of well survey calculations by order of magnitude with numerical approximation. Although the most precise method of simulating and calculating a wellbore ...
