Simulacro
El Heraldo; Universidad Distrital Francisco José de Caldas. Facultad de Ciencias y Educación. Centro de Documentación de Ciencias Sociales.
The image contains a news article about a military simulation conducted to commemorate the anniversary of the Battle of Ayacucho. It describes the strategic exercise, which involved multiple battalions and leaders, on the slopes of Guadalupe. The simulation recreated defensive and offensive positions, demonstrating tactical maneuvers and commemorating military history. This article was published in El Heraldo on December 11, 1889.
20 de julio
El Heraldo; Universidad Distrital Francisco José de Caldas. Facultad de Ciencias y Educación. Centro de Documentación de Ciencias Sociales.
The image contains a news article about the July 20th celebrations in Bogotá, highlighting the procession, fireworks, military parades, and religious and cultural events. It also mentions details about the army uniforms and the elegant decorations in Plaza de Bolívar and the Metropolitan Church. This article was published in El Heraldo on July 23, 1890.
Revisión y actualización a bases de datos de los predios del aeropuerto el Edén Armenia - Quindío pertenecientes a la aeronáutica civil
(Universidad Distrital Francisco José de Caldas) Sandoval Parra, Sharon Viviana; Aldana Boutín, Rose Marie
Civil Aeronautics, among its many functions, is responsible for managing the properties acquired for the construction of infrastructure or real estate suitable for aeronautical and airport activities in Colombia. For this reason, it has the obligation and responsibility to keep this information organized and updated according to the geographic information presentation standards established by IGAC. Therefore, there is a need to update and/or create the databases and information on properties already acquired by Civil Aeronautics, in order to verify their validity or accuracy, as their status is unknown due to their age. Additionally, considering the changes in the cartographic presentation standards made by IGAC in 2020, it is also necessary to update the cartographic projection to the unique national coordinate system. This document presents a detailed analysis of the cadastral and physical information of the properties belonging to Civil Aeronautics at El Edén Airport. The main objective is to verify the consistency between the legal information (public deeds) and the physical information (plans, topographic surveys) of each property, in order to identify possible discrepancies and propose solutions. Through a rigorous methodology involving data collection, analysis with specialized software, and comparison with technical standards, it has been possible to identify and quantify the existing differences between legal and physical information. The results obtained are of great relevance for updating the cadastral database of Civil Aeronautics and for future decision-making related to the management of these properties.
Descubrimiento de América
Diario de Cundinamarca; Universidad Distrital Francisco José de Caldas. Facultad de Ciencias y Educación. Centro de Documentación de Ciencias Sociales.
The image contains a news report about a nighttime parade called the "March of the Torches," with Army participation, fireworks, and a large crowd in Plaza de Bolívar. There was also Mass in the Cathedral, a blessing of monuments, and a festive atmosphere with flags and decorations. It was a very well-attended and solemn celebration. This news report was published in the Diario de Cundinamarca newspaper on October 15, 1892.
Integración y comparación de técnicas de aprendizaje automático y modelos de regresión por bosques aleatorios en el proceso de predicción de parámetros de ecuaciones de perfil fustal para la especie Eucalyptus pellita
(Universidad Distrital Frnacisco Jose De Caldas) Levy Molano, Juan Sebastián; Leal Pulido, Robert Orlando
This study evaluates and compares the effectiveness of traditional taper models optimized using neural networks (NN) and random forests (RF) to accurately estimate the volume of individual Eucalyptus pellita trees. Nine traditional models were fitted using the Levenberg-Marquardt algorithm, with the three best models (Riemer, Bigging, and Rentería) selected, achieving coefficients of determination (R²) of 99.54%, 99.2%, and 98.57%, and RMSE values of 0.17, 0.22, and 0.29, respectively. The models were then optimized using NN (backpropagation and recurrent networks) and RF, demonstrating superior performance compared to the base models. Recurrent NNs showed lower training and testing losses, and the Riemer model optimized with backpropagation (RMSE: 0.183, R²: 0.944) stood out for its balance between accuracy and complexity, making it suitable for practical forestry applications due to its robust R² and fewer parameters. This study highlights the potential of machine learning for simultaneous prediction of stem profile parameters and volume, enhancing efficiency in forest volume estimation with significant implications for forestry planning and management.
