In the evaluation of terrestrial coverage by means of remote sensors, we find a variety of techniques dedicated to be able to register the terrestrial coverage, one of them is the use of optical satellite images also known as multispectral images, these images are formed by different bands of spectral that depend on the optical sensor of the observation satellite, among the known bands we have: Panchromatic, Red, Green, Blue, Near Infrared, among others. The analysis of multispectral images is based on the grouping of these spectral bands, forming color images by grouping three spectral bands; One of the disadvantages presented by optical images in the acquisition is the presence of cloud cover that prevents the registration of land cover. Another of the techniques used is the use of the images provided by the Synthetic Aperture satellites, better known as radar images (SAR). These image...

When we refer to pain, we are faced with an unpleasant sensation that causes certain reactions in the human body that prevent its production, so it is of vital importance to understand what the symptomatology of pain is, how it is produced and how it can be avoided. production, there are cases where the pain becomes pathological where found in the patient's thoughts, therefore the present work tries to demonstrate that its production can be avoided in the face of intense painful situations that occur when working in the recovery of the mobility of the patient. articulation of the knee, which by its nature is painful, added to the fear of feeling pain on the part of the patient does not help the patient's recovery, the experimentation consists of taking the pain from the approach of not thinking about it and relaxing and evaluating it by an environment of cerebral analysis through the lev...
