Ítem Análisis estadístico de dos parámetros de rayo en zona tropicalRubiano Cruz, Jonathan Jair; Chacón Cardona, Cesar Alexander; Torres Sánchez, HoracioAt present it does not possess a mathematical model that indicates the behavior of the current return parameter lightning in tropical zones, zone comprising a country like Colombia, for this case study is paramount for its high electrical activity of atmospheric origin. in the literature it is ensured that in the tropics current magnitudes rays are much higher than in middle and high latitudes, therefore, given the intense atmospheric activity in the zone of intertropical convergence the risk of death by electric shock It must be determined for our nation. Certainly spoken in these tropics magnitudes rays are higher, therefore, it is necessary to associate the high magnitude and high activity can talk about electrical risk that in the case of this project is also vital since neither we possess an equation that tells us the probability of risk of death by lightning in Colombia.Ítem Determinación del comportamiento de la constante dieléctrica en función de la frecuenciaGonzález Riaño, Oscar Julián; Vega Valencia, Brayan Andrés; Chacón Cardona, Cesar AlexanderThis paper demonstrates the behavior of the class II dielectric constant of ceramic capacitors in function of frequency up to 10Mhz, by implementing and adapting a low-cost electronic circuit. This circuit is based on the MAX4182 operational current amplifier that measures the complex capacitance of a capacitor; the information is processed through the Matlab program, finding the decrease in dielectric permittivity, as well as the tangent of losses associated with the behavior of the imaginary part.
