Explicit expressions for the reconstruction of the diffusion coefficient are also provided. Such results hold for a large class of boundary conditions for the elliptic equation in the two-dimensional setting. In three dimensions, the results are proved for a more restrictive class of boundary conditions constructed by means of complex geometrical optics solutions. ]]> Guillaume Bal, Eric Bonnetier, François Monard and Faouzi Triki Wed, 1 May 2013 08:00:00 GMT http://www.aimsciences.org/test_aims/journals/displayPaper.jsp?paperID=8634 Near-field imaging of the surface displacement on an infinite ground plane http://www.aimsciences.org/test_aims/journals/displayPaper.jsp?paperID=8634 Gang Bao and Junshan Lin Wed, 1 May 2013 08:00:00 GMT http://www.aimsciences.org/test_aims/journals/displayPaper.jsp?paperID=8635 Gaussian Markov random field priors for inverse problems http://www.aimsciences.org/test_aims/journals/displayPaper.jsp?paperID=8635 Johnathan M.

We derive a certain class of stochastic partial difference equations by starting from second-order stochastic partial differential equations in one and two dimensions. We discuss discretisation schemes on uniform lattices of these stationary continuous-time stochastic processes and convergence of the discrete-time processes to the continuous-time processes. A special emphasis is given to an analytical calculation of the covariance kernels of the processes. We find a representation for the covariance kernels in a simple parametric form with controllable parameters: correlation length and variance. In the discrete-time processes the discretisation step is also given as a parameter. Therefore, the discrete-time covariances can be considered as discretisation-invariant. In the two-dimensional cases we find rotation-invariant and anisotropic representations of the difference equations and the corresponding continuous-time covariance kernels. ]]> Lassi Roininen, Petteri Piiroinen and Markku Lehtinen Wed, 1 May 2013 08:00:00 GMT http://www.aimsciences.org/test_aims/journals/displayPaper.jsp?paperID=8647 Perfect pulse-compression coding via ARMA algorithms and unimodular transfer functions http://www.aimsciences.org/test_aims/journals/displayPaper.jsp?paperID=8647 Lassi Roininen and Markku S.
