This work presents a revision of four different registration methods for thermal infrared and visible images captured by a camera-based prototype for the remote monitoring of diabetic foot. This prototype uses low cost and off-the-shelf available sensors in thermal infrared and visible spectra. Four different methods (Geometric Optical Translation

The European Solar Telescope (EST) is a 4-m class solar telescope that will include a Multiconjugate Adaptive Optics system (MCAO) integrated in the telescope optical path. Its open-dome configuration implies that the complete telescope will be exposed to wind, having an important impact in image stability and quality. The integration of Active

Empirical constraints are master keys for testing theoretical evolutionary model predictions. In massive stars, the region in the Hertzsprung-Russell diagram (HRD) in which the Blue Supergiants (BSGs) are located sets several important constraints to the models, and in particular to the theoretical end of the main sequence (MS). So far, we are
