This thesis work begins with the revision of state of the art about active magnetic bearings (AMB), the mathematical methods used to obtain geometric and physical parameters that will influence in the mechanical, electrical design and control system proposed by this prototype. The control system will activate the magnetic bearing to center its shaft, for which it is joined a variable load in order to study the best control performance under different load over the rotor proposed by requirements. When the rotor is not controlled in its own axis even though variable load, a position error will occur that will be corrected by the program of a control system that will center the shaft (rotor). For this design was evaluated generalized AMB models [2], [3], [4] to validate the best identification for this design, furthermore as a consequence to get the best performance for the control system a...

In this research is analyzed COVID-19 transmission by thermodynamic and energy balance between geographic areas and its correlation with possible COVID-19 transmission between 2 persons at least. In order to achieve parameters for medical doctors, as for example the minimal distance among two infected people, who have this virus, there were designed mathematical models that were based in statistical data to get information of COVID-19 propagation as the dependence on temperature of geographic areas, moreover the thermal effect of the minimal distance between two people avoiding COVID-19 infection. With this work, answers are sought to the questions: if it could be possible to find a relation between temperature and virus transmission? Or if it could be possible to get a correlation variable among thermal variables with minimal distance separation (it was described above) for two people? ...

This research explains the applications of the algorithm that was designed to provide statistical support for medical doctors. The support that was achieved from this research looks for an urgent interpretation of parameters such as the rate of infected people by COVID-19 and the rate of deceased people because of this virus. Furthermore, this research achieves prediction rates that were provided by a mathematical model that observes and adapts real statistical data from other countries, where governments are trying to find solutions against of COVID-19 propagation. It means, in order to get accuracy in prediction results, it was necessary to analyse what was the statistical behaviour from China and other countries that returned to normal activities as it was before virus imposed to confine population inside homes. On the other hand, it is summarized the virus problematic growth and some...

Esta investigación explica las aplicaciones de reconstrucción tridimensional (3D) para las imágenes de las familias COVID-19, según la búsqueda de la correlación entre el modelo matemático "evento por evento" con efecto antiviral sobre el virus, además, el modelo matemático obtenido de la reconstrucción 3D está correlacionado con "Un modelado matemático general para las respuestas inmunitarias". Por lo tanto, el algoritmo diseñado, proporciona apoyo a los médicos a través de un análisis gráfico y predicciones con respecto a "¿Qué sucede con el virus antes de aplicar una acción como los medicamentos contra la malaria?". Muchos países están tratando de encontrar la vacuna contra COVID 19; sin embargo, muchos países sólo tienen estrategias estadísticas dadas por las restricciones de desplazamiento de la población, lo cual no es suficiente para evitar la rápida  t...

It is proposed in this abstract some suggestions for the manufacturing of advanced sensors (smart sensors) that are based in amorphous nanostructures in order to prepare intelligent sensors from which their transducers elaboration need specific requirements, such as in geometry and material of every sample. Moreover, it is quite important the correlation understanding between the necessities of the community or company that will operate with them. It means, the manufacturing of the transducers samples can be prepared by sputtering process, atomic load deposition and also by electrochemical reactions. Hence it is suggested to analyze the chemical components that are possible to find in the Andes mountains, also the strict compromise of the responsible residual collection of every production step and caring the environment conditions. Furthermore, it is proposed that designers could get un...
