- ÍtemAnálisis de suelos por medio de fotogrametría con aeronaves no tripuladas para realizar operaciones militares(Fundación Universitaria Los Libertadores. Sede Bogotá., ) Torres Valencia, Hernán Darío; Orduy Rodríguez, Jaime Enrique; Lozano Tafur, Cristian (Codirector)The soil is made up of several elements among which are minerals, organic matter, organisms, air and water and this is formed due to different factors such as erosion and decomposition by microorganisms, these elements can be identified by means of analysis of variables such as temperature. The analysis that is carried out on the soils constitutes a process for the acquisition of data and relevant information on its composition and main characteristics, in order to identify the type of soil that exists in the field and in several cases provide detailed information about this same. On the other hand, the quality of the terrain is an important factor that can significantly affect the success of military operations. In many cases, the site where these special operations take place may have unique characteristics. In Colombia, these operations are carried out in swamps, dense forests or mountainous areas, which can affect the ability of troops to move efficiently, as well as reduce the maneuverability of weapons and the functionality of vehicles. Therefore, carrying out a detailed analysis of the soil can help the Military Forces to better understand the terrain in which they operate and make decisions, in addition to knowing the presence of antipersonnel mines. For this reason, the objective of soil analysis is the optimization of military resources in addition to time; for assertive decision making. A method for the analysis of the terrain through unmanned aircraft systems and aerial photography is presented, making a comparison of variables and images that will help this decision making for its future implementation in Colombian troops.

- ÍtemMontaje de un sistema de inyección controlado por electroválvulas e implementación del sistema extintor de incendios en un banco de pruebas para lavado de inyectores(Fundación Universitaria Los Libertadores. Sede Bogotá., ) Abarka Rojas, Jesús Eduardo,; Sierra Fula, Duban Andrés;; Orduy Rodríguez, Jaime EnriqueTogether with the Army Aviation School (ESAVE) and the Los Libertadores University Foundation; It is intended to develop the automation of the Bank of injectors washing, which is in operation manually in the engine workshop located in the Aircraft Maintenance Battalion No.1 of the National Army; in the same way, it is expected to make the appropriate adaptation of the fire extinguishing system, in order to prevent accidents due to the use of fuel required to carry out the operation described above; taking into account that in the washing procedure the operator has direct contact with the fuel, which causes health risks for those who perform such work. So, to solve this problem it is necessary to develop technological innovations, such as the implementation of electronic systems that facilitate, and at the same time improve the conditions in which the procedure is done, reducing fuel consumption and energy normally would use with the manual process, since with a system controlled by solenoid valves a smaller amount would be spent. Thus, the design and manufacture of an electronic solenoid valve control system will eliminate the risks to which technicians are exposed, reduce awkward positions and control fuel spillage around the bank. However, it should be noted that, for the development of the project, it is required in the first instance, the creation of an electronic card, which integrates the programs and allows the control of opening and closing of each of the four valves used for this process. So, the electronic card and the programs must have electrical characteristics that allow the software and hardware to communicate; The electronic card that integrates the programs has the ability to receive 12V DC at 20A, where 12A will be used for valve activation, and a USB port that allows connection to a Tablet. 24 It should be noted that, for the development of the software, the LABVIEW program will be used, which replaces the manual operation of closing and opening the valves by the operator

- ÍtemPropuesta de emplazamiento para la implementación del segmento terrestre de un sistema tipo SBAS en el territorio colombiano(Fundación Universitaria Los Libertadores. Sede Bogotá., ) Mosquera Medina, Juan Manuel; Rincón García, Christian Yesid; Orduy Rodríguez, Jaime EnriqueSBAS is an augmentation signal for the satellite system GNSS type. The system is composed of four different segments: Ground, Space, Stakeholder and Communication Segments. The Ground segment receives the positioning signals by the atmosphere layer named ionosphere. This error generates that the aircraft real position has a difference up to 100 meters to the position that is calculated by the navigation satellites. The Ground Segment is composed of: the reference stations, master station and the link station. The reference station intercepts the direct positioning signals of the communication satellites, by means of RMS antennas, hence, the signal to the master station is transmitted. The master station calculates the positioning error, furthermore it sends the signal along with the correction to the link station. The link station sends the positioning signal collected to the satellites of the space segment, these satellites direct the positioning signal to the aircrafts and to the reference station with the objective of monitoring the signal. This project developed some simulations in different systems such as Orbitron, RadioMobile and STK. The analysis of the results of this simulation focused on the Colombian air operations were discussed along with the recommendations and conclusions obtained based on the Objectives established for the project.
- ÍtemPropuesta de estrategia pedagógica para la resolución de problemas con adición, sustracción, multiplicación y división de números naturales, para los estudiantes de grado cuarto dos de la I.E. Carlos Castro Saavedra de Pereira(Fundación Universitaria Los Libertadores. Sede Bogotá., ) Marquinez Realpe, John Andrés; Orduy Rodríguez, Jaime EnriqueAccording to Resnick (1989), the pedagogical strategy concept is directly related to the teaching and learning processes that are generated between the teacher and the students, in which activities are combined to develop pedagogical practices effectively. This document seeks to generate a proposal for a didactic strategy to respond to fourth-grade students' difficulty in solving problem situations. Among the difficulties are reading comprehension, the interpretation of the problem, and the difficulty in proposing alternatives to troubleshoots. Designing a strategy for solving a problem promotes the development of mathematical skills based on mathematical procedures and knowing how, when, where, and why to use them in an argued and reasonable manner. The strategy proposes the generation of didactic activities such as games, shopping at the school store or the neighborhood store, applying measurement by calculating length, height, weight, size, or quantities, and using some tools such as the meter or the scale. The methodology is focused on classroom work, developed through didactic sequences, performing the following steps: Understand the problem, Set up a plan, Execute the plan: and look back so that the student has the opportunity to review their work and make sure if you didn't make a mistake. This research work is carried out within the master’s degree in Education of the Fundación Universitaria Los Libertadores. It focuses on designing a pedagogical proposal based on problem-solving to strengthen the spatial-metric component of mathematical thinking in students of the fourth grade of the Carlos Castro Saavedra Educational Institution of the township of Puerto Caldas, municipality of Pereira. Finally, the models and other elements, directly and indirectly, related to the problem situation carried out by the students are presented and registered on several billboards that receive the name of collective evidence.
