Let A be an n-point set in the plane. A discrete X-ray of A in direction u gives the number of points of A on each line parallel to u. We define F(k) as the maximum number n such that there exist k directions u_1,...,u_k such that every set of at most n points in the plane can be uniquely reconstructed from its discrete X-rays in these directions. We establish a mildly exponential lower bound F...

Este artigo tem como objetivo apresentar a proposta metodológica da filósofa italiana Angela Ales Bello para se compreender o sentido experiência religiosa. Apesar das críticas em relação à fenomenologia e sagrado, partimos do pressuposto de que todas as áreas formam campo intradisciplinar Ciência Religião – Fenomenologia é uma delas contribui, seu modo, abordagem fenômeno religioso. Desse part...

In the context of ESA Climate Change Initiative project, a new coastal sea level altimetry product has been developed in order to support advances variability studies. Measurements from Jason-1,2&3 missions have retracked with Adaptive Leading Edge Subwaveform (ALES) Retracker and then ingested X-TRACK software best possible set corrections. These two processing approaches, previously successfu...

It is widely believed that altimetry-derived sea surface heights (SSHs) in coastal zones are seriously degraded due to land contamination in altimeter waveforms from non-marine surfaces or due to inhomogeneous sea state conditions. Spurious peaks superimposed in radar waveforms adversely impact waveform retracking and hence require tailored algorithms to mitigate this problem. Here, we present ...
