Technology makes many of the tasks that were previously difficult to perform, nowadays can be solved, one of them is to be able to carry out studies on large tracts of land and at the same time be able to have a level of detail of them, through the study of the satellite images provided by the Earth observation satellites, these images are composed of a series of spectral bands that will depend on the type of satellite mission that was conceived and the optical instrument that is found as a payload, these images are represented by multidimensional arrays and large size, so computational high computation equipment is required to process the images, added to this requires specialized software that allows the visual interpretation of satellite images. To be able to work with satellite images you have many configurations, normally you work with the configuration of separate bands that consis...

When it is required to study the terrestrial coverage in large dimensions, the use of remote sensors is used, these provide us with information according to the type and coverage that they present in their configuration, these remote sensors present in general two types of images in accordance To the instrument they have on board, we first have the optical sensors that are on board the observation satellites, which provide information of the terrestrial coverage based on a representation of pixels that make up an image, they are characterized by the bands of colors Red, Green, Blue and in other bands such as short wave infrared and medium wave infrared among others that may have according to their purpose, these images present a level of detail according to their special resolution that can be metric and sub metric, one of the disadvantages of these sensors is that in the presence of clo...

In the new times we are living, the use of technology is causing many of the customs are changing, one of them is the development of children, in previous years children used to play with their friends in the parks, technology It has caused many of them to perform recreation activities based on the use of video games, these games have caused children to develop certain skills and also change their behavior when they perform certain activities, in this work a comparison between the levels of concentration and meditation levels when children carry out activities related to the realization of academic activities related to the accomplishment of the school tasks that they must perform, with the levels of concentration and meditation when the child is doing activities related to video games, methodology that was used to evaluate the levels The concentration and meditation is based on the use ...

Diabetes Mellitus is a metabolic disease characterized by the presence of elevated blood glucose levels. Diabetes itself causes other chronic complications, including an eye disease known as diabetic retinopathy. Nowadays, diabetic retinopathy is the most frequent cause of blindness among the active population of developed countries. The principles that produce this disease are not completely known and can not yet be prevented. However, there are effective treatments that delay their evolution as long as it is diagnosed with sufficient anticipation. The problem of diabetic retinopathy is that it is an asymptomatic disease and only defects appear in the vision at an advanced stage of the disease. So in the early stages of diabetic retinopathy is usually imperceptible, diabetic patients do not realize that they have the disease and do not undergo an eye examination. Sometimes the patient i...

Graduated motor imagery is the technique used in rehabilitation therapies, for the treatment of chronic pain and in most cases for movement disorders, the technique consists in strategically presenting therapies that correspond to laterality perception, mirror therapies and motor imagery. In the present work a mechanism was designed that facilitates the patient to learn about the movement mechanisms and the way in which the movement interacts with the extremities of the upper and lower limbs, the design is based on being able to use 24 images of the upper limbs and lower, these images are grouped into two groups with a different background, one dark and the other light, these images are grouped and sequentially arranged in a video, each image has a duration of 2 seconds in the video, after this time the image, at the time each image is displayed, the patient raises his hand that correspo...

When we want to work with signals produced by the human body, we face different challenges that we must address, from the sensor to be used, through the conditioning of the signal for later registration and analysis, these stages are important to have a Good record of the clean interference signal that are foreign to the signal. One of the challenges you have when working with the electromyography signal, is to be able to understand the behavior of the muscles accompanied by the biophysics of the movement that is performed, for your better understanding and analysis the monitoring of several muscles at the same time is required, what originates a multichannel record, this condition is a complex requirement at the time of being able to design a team that can perform this multi record, being able to record these signals is vital for a subsequent analysis and understanding of muscle activit...
