Numerical results from a regularization method for inversion of Fourier series
No full textThe author consider the problem of recostructing a periodic function when only an approximation of the sequence of its Fourier coefficients is known. A proposed method of regularization is tested from the qualitative point of view
An energy interpretation of a stationary functional for the variational solution of the nonlinear Poisson equation in semiconductors at thermal equilibrium

Statistical check on the smoothing parameter of a method for inversion of Fourier series
No full textA method by the authors allows to approximate a function by using its Fourier polynomials with noisy coefficients. In order to verify wheter this method is of interest in applications, the authors perform some tests with respect to both the pointwise and the uniform approximations. In this paper results of these checks are presented
