Cálculo de la Incertidumbre en la Medición Visual de los Parámetros de un Péndulo de Foucault

We present a method for determining the uncertainty in the measurement of parameters that describe the dynamics of a Foucault's pendulum. In the document, we review how these parameters can be obtained. Then, we propose a method for evaluating the uncertainty in their determination. We illustrate the method with experimentation made on a 28m height pendulum located at 20° 35' north latitude.

Filtro de restauración de imágenes basado en la transformada discreta del coseno y el análisis de componentes principales

An algorithm for restoration of the images contaminated by additive white Gaussian noise is proposed. The groups of patches are found by the proposed block similarity search algorithm of reduced complexity performed on block patches in transform domain. When the noise variance is small, the proposed filter uses an additional stage based on principal component analysis; otherwise the experimenta...
