- ÍtemAdquisición y procesamiento de señales eléctricas de un banco de pruebas para motores de combustión interna(Fundación Universitaria Los Libertadores. Sede Bogotá., ) Acevedo Pérez, Edwin; Morales Medina, Juan Pablo; García Mariaca, Alexander; Jiménez Alvarez, Andrés CamiloThe proposal of this project is to install an instrumentation system in a test bench for internal combustion engines to evaluate the performance and performance of a 4-stroke diesel engine, in order to generate electric power through an alternator and check the total power delivered when connected to a resistance bank, which will be fed with two types of fuel, common diesel fuel and LPG gas fuel. For this, several types of sensors are implemented to evaluate in real time all the variables involved in the operation of the engine. The instrumentation system is composed of several modules which are constituted by the sensors installed in the bank, such as k type thermocouples for temperature measurement, torque sensor for torque measurement, encoder for measuring RPM, air mass sensor o MAF for measuring the flow of air entering the engine and has an activation control on the LPG LPG injection valves. With the complete system, performance tests are carried out on the engine in different speed parameters with the aim of obtaining, visualizing and storing the status of the variables that are being measured and afterwards carrying out the corresponding analysis of the engine operation.

- ÍtemAlgoritmo de machine para detectar movimientos técnicos en el juego de tenis de campo, como el revés, derecha y saque.(Fundación Universitaria Los Libertadores. Sede Bogotá., ) Arrieta Blanco, Yesid Ramiro; Rivera Yemayuza, Randhy Alejandro; Medina Velandia, Lucy NohemyThrough this project a software for the detection of technical movements in the sport of field tennis was made, the objective was to recognize the blows of the reverse, right and take-off type in order to automate their counting within a fragment of a tennis match. In addition, a final statistic was generated, totaling the number of hits made by a player. The software relied on Machine Learning through the use of convolutional neural networks. It was concluded that it is possible to create software that can account for such hits, because when performing the tests, each hit could be detected correctly. It is necessary to take into account that there are many external factors that can affect the accuracy of statistics, to counteract these effects it is necessary to include new classes and objects in the detection.

- ÍtemAlgoritmos computacionales para los vectores de estado de los planetas del sistema sol(Fundación Universitaria Los Libertadores. Sede Bogotá., ) Álvarez Páez, Héctor Alejandro;; Nisperuza Toledo, Jorge LuisIn orbital mechanics the vectors of position and velocity status are the basic elements for the kinematic and dynamic description of any system in orbital mechanics, this description depends on an analysis defined by the problem of two bodies, which is focused on the analysis of the temporal variable. Taking into account the above and highlighting the need to develop a proprietary algorithm for investigative use in the framework of the study of interplanetary transfer paths, this grade work aims to develop computational routines in Wólfram Mathematica®, which will allow obtaining position vectors and speed of the planets of the solar system. Specifically, the equations related to the velocity and position of the planetary movement will be synthesized, and will be related to the design of deterministic algorithms, whose final result will be a computational code that will allow obtaining the position and velocity, for all the planets of the solar system, which will graph the relative position with respect to the sun of the selected planet. Additionally the planetary ephemeris will be revealed, which describe the positions with respect to a heliocentric plane. Likewise, there is a corroboration of the computational routines, they will be contrasted with the computational packages of the study medium, such as the computational package provided by Curtis elaborated in Matlab® and the specialized Stellarium software. This comparison will be mediated with a series of input data generated for each planet in the solar system. Defining this, an analysis of the results will be developed to finally validate the project
- ÍtemAlgoritmos computacionales para órbitas de transferencia(Fundación Universitaria Los Libertadores. Sede Bogotá., ) Gil González, Edward Andrés; Nisperuza Toledo, Jorge Luis; Ballesteros Ballesteros, Vladimir Alfonso, (codirector)The calculation of interplanetary trajectories is an active topic of research given the constant sending of probes to the different planets of our Solar System. In this sense, this project addresses the development and implementation of computational codes in the calculation of transfer paths for sending interplanetary probes, making use of Hohmann-type paths with gravitational assistance in intermediate steps. In this work, the orbital elements and the graphs for the trajectories of probes sent from the Earth to some planets of the Solar System, as well as other types of planetary systems are determined, corroborating the results with missions already carried out and obtaining adequate transfer paths for the planets under consideration for a set period. The results of this research acquire relevance since they will be useful for the scientific community interested in future interplanetary missions, including the different international space agencies.

- ÍtemAnálisis aeroacustico de una tobera convencional(Fundación Universitaria Los Libertadores. Sede Bogotá., ) Muñoz Ramirez, Sebastian; Vaca Rios, John JairoThe Computational Aero Acoustic field (CAA) has become in the basis of many Mechanical issues in the last decade specially in Aeronautical and Aerospace Engineering and is one of the nearly simulations nowadays and it requires a great computational power due the random order that manage the gas elements behaviors, For this reason in scientific literature is common to find that every single acoustic simulations is supported by computational fluid dynamics (CFD). The goal is to reduce the computational power that requires many variables on the acoustical phenomenon and this way create attractive methods to apply in many industrial fields where accurate results and short periods of time are necessary in the design process. In this case it will make a simulation to analyze the aero acoustical phenomena at the nozzle exit.

- ÍtemAnálisis aerodinámico computacional de una superficie hipersustentadora en el borde de la salida de un plano(Fundación Universitaria Los Libertadores. Sede Bogotá., ) Nova Gomez, Edward Mateo; Ávila Granados, Diego LeonardoIn this project, a high-lift device will be designed; it will be located in the upper rear section of the aerodynamic airfoil, in the area known as the extrados. The aim is to know the behavior of the airflow in the presence of the mentioned device, considering that it will have the ability to move both longitudinally and vertically; the analysis will be carried out through simulations in the software ANSYS Fluent. Based on the results of the simulations, the aerodynamic behavior will be analyzed, determining the effectiveness of the high-lift device in the main stages of flight, such as take-off, landing and cruise flight. Due to the importance of hyper-lift surfaces in an aircraft, it is required a configuration that increases the lift in the take-off phase, keeping drag as low as possible, this together with a landing configuration that generates high lift along with a high drag index, and finally allow the highest lift/drag ratio to be achieved in the cruise phase. The previous scenarios will be an indication of the efficiency of the design to be studied
