Diseño de un sistema de medición de temperatura para líneas de transmisión y distribución de energía utilizando sensores ópticos basados en redes de difracción de Bragg
(Bogotá - Ingeniería - Maestría en Ingeniería - TelecomunicacionesUniversidad Nacional de Colombia - Sede Bogotá, 2020-04-14)
Las redes de transmisión de energía son limitadas principalmente por dos factores, flecha de la catenaria, cuyo aumento lleva a incumplir distancias de seguridad, y la temperatura del conductor, cuyo aumento produce pérdidas ...
Medición de variaciones espacio - temporales de la temperatura del agua en su interacción superficie y el subsuelo utilizando redes de difracción de Bragg en un tramo de un arroyo de montaña colombiano
(Bogotá - Ingeniería - Maestría en Ingeniería - Ingeniería ElectrónicaUniversidad Nacional de Colombia - Sede Bogotá, 2020-02-07)
This final master's project presents the optical sensors based on fiber Bragg gratings (FBG) as a possible solution for the measurement of spatiotemporal variations of temperature in hydrological applications. Specifically, ...
Detection of sharp symmetric features in the circumbinary disk around Ak Sco
