ATMOSPHERIC DISCHARGE RECEPTION ANTENNA.

The design of an electric field antenna to detect an electromagnetic pulse caused by an atmospheric electrical discharge was successfully carried out. Design criteria in engineering and typical parameters of lightning were taken into account. Different types of antennas that met the criteria to characterize the discharges were compared and the most suitable one was chosen, based on principles of practicality, physical working element and a flexible bandwidth. Robust documentation on the subject was used to describe the natural phenomenon and checks were made with the Matlab software to verify the behavior of the antenna, based on the physical standards of electromagnetic theory. In addition, simulated results were compared with results obtained from experiments carried out at a national level. This allowed to guarantee the effectiveness of the design of the electric field antenna to detect an electromagnetic pulse caused by an atmospheric electrical discharge. The results obtained were satisfactory, providing an effective solution for the characterization of atmospheric electrical discharges. The design of an electric field antenna is a key piece in the detection of electromagnetic pulses. This technique is very useful for the study of atmospheric electrical discharges, as it can detect the presence of lightning with greater precision. This is because the electric field antenna is sensitive to both the pulse wave and the radiation wave. It is also useful for detecting signals emitted by electronic devices, which allows for better identification of such devices. In conclusion, the design of an electric field antenna to detect an electromagnetic pulse caused by an atmospheric electrical discharge was successfully carried out, meeting the established criteria. This allowed for greater precision in the detection of electromagnetic signals and better characterization of atmospheric electrical discharges.

IMPLEMENTACIÓN DE COFRE INTELIGENTE PARA ADMINISTRACIÓN DE LLAVES.

El presente documento describe los criterios y proceso de diseño bajo los cuales se realizó un cofre inteligente para administración de llaves, el dispositivo se construyó con la intensión de brindar una alternativa para conocer la trazabilidad los eventos asociados a cada uso de las llaves que se manejan en un complejo con un número alto de cerraduras, adicionalmente, cuenta con un método 2FA (Two-factor authentication) para el control de acceso con el que se pretende que el usuario final y responsable de las llaves tenga la seguridad de saber quién, cómo y cuándo se tomó cada llaves, permitiendo así que la trazabilidad de los acontecimientos se mantenga en el tiempo con la integración de una base de datos. Sin dejar de lado el componente digital del sistema, en el que por medio de una página web se gestiona y se organiza la información registrada para cada operación en la base de datos. El prototipo final cuyas dimensiones son de 40x40x20 cm cuenta con una cámara integrada para realizar la autenticación biométrica, que corresponde al reconocimiento facial por medio de inteligencia artificial.
