The electrocardiogram (ECG) is a diagnostic tool that records the electrical activity of the heart, and depicts it as a series of graph-like tracings, or waves. Being able to interpret these details allows diagnosis of a wide range of heart problems. Fetal electrocardiogram (FECG) extraction has an important impact in medical diagnostics during the mother(More)
The first purpose of this paper is to investigate time-harmonic Maxwell's equations in Lipschitz and multiply connected cavities of R 3. We prove the wellposed-ness of the current source problem by means of a new formulation. Our starting point is the curl second order equation satisfied by the magnetic field. The use of an appropriate compact operator is(More)
The deconvolution problem in image processing consists of reconstructing an original image from an observed and thus a degraded one. This degradation is often modelled as a linear operator plus an additive noise. The linear operator is called the blurring operator and the goal consists of deblurring the image. Very often, the blurring operator is modelled(More)
