Ítem Migración e implementación de servidor local a hosting cloud para proyectos de software en entornos empresarialesDíaz Herrera, Iván Leonardo; Peña Valencia, David Andrés; Plazas Nossa, LeonardoThis degree project in internship mode is based on migrating an on-premise server located at Compensar establishment to a Linux server in the cloud using the different services of "Amazon Web Services" (AWS) considering the network configuration, applications, protocols, security and backup. Oras Technologies company provides software services in information analytics and monitoring, database management, activity control and information integration of mobile applications. This migration intends not to depend on the network and energy infrastructure provided by the client, since limitations have been evidenced that have slowed down the development of new projects. Therefore, new alternatives are sought to allow the growth and magnitude of future innovations that contributes to society.Ítem Método para la síntesis de paisajes de optimización bidimensionales basado en redes adversarias generativasMedina Muñoz, Mariana; Melgarejo Rey, Miguel AlbertoThe implementation of an artificial neural network, specifically a Deep Convolutional Adversarial Adversarial Network (DCGAN), was carried out in order to generate two-dimensional optimization landscapes. The number of landscapes and their diversity were increased. We started with the creation of a database based on the literature, to later produce other databases with specific characteristics. Eight databases were created, the first four of which were divided into: Original, No noise, With a single minimum and With several minimums. The 4 subsequent databases were created from the application of a Data Augmentation to the 4 previously mentioned databases. Then, the algorithm was run several times until the appropriate parameters for the operation of the network were found, this was done for each of the databases. Once the parameters were chosen for each of the databases, the algorithm was run again several times to perform an analysis of the results and also obtained several optimization landscapes with different characteristics, with similarity to the original database and at the same time, with the presence of different information. From all the experimentation it is validated that it is possible to generate new two-dimensional optimization landscapes from a generative adversarial network, leaving as future work to find the functions or mathematical expressions that will produce such landscapes.Ítem Construcción de un sistema de gestión y administración de datos de un RMD, basándose en SNMP, utilizando prometheus como colector y grafana como graficadorRodriguez Rubiano, Juan Manuel; Puerto Leguizamon, Gustavo Adolfo; Puerto Leguizamon, Gustavo Adolfo [0000-0002-6420-9693]This report registers the process of building a data management and administration system presented as a Dashboard, which contains information on the status of a RMD network device provided by Prometheus software, which obtains the information using the SNMP protocol and is graphed with the help of Grafana for the final presentation of the information as a Dashboard.Ítem Evaluación de integración de una cámara Alticam al sistema de comando y control de un RPAS de vigilancia tipo multirrotor de la Fuerza Aérea Colombiana.Perdomo Mora, Mariacamila; Cuevas Sua, Juan Camilo; Ovalle Martínez, Diana Marcela; Medaglia Lopez, Sara Gabriela; Ovalle Martínez, Diana Marcela [0000-0002-3650-4273]In Colombia, the study of unmanned aircraft began in 2006 thanks to the Colombian Air Force, specifically with the Scaneagle line. These aircraft are used for intelligence, surveillance and reconnaissance missions against terrorist organizations, taking advantage of their autonomy and small size. The Scaneagle model has an Alticam camera manufactured by HOOD TECH, but its operation is limited by software and it is unknown how it interacts with the hardware. To effectively reuse the obsolete cameras, the Air Force's Center for Aeronautical Innovation Technology (CETIA) proposed integrating one of them into the command and control system of a multirotor surveillance RPAS. A reverse engineering process was performed to decode the camera commands and an ARDUINO UNO microcontroller was used as a translator. A wireless system was implemented using Herelink radio control, consisting of a ground controller and an aerial unit that connects to the drone. A mount was designed to install the camera on the drone, ensuring stability and reducing vibrations. The main objective of the project was to reduce planned obsolescence and take advantage of the discarded Scaneagle cameras in future RPAS, saving significant costs. This will allow the Colombian Air Force to carry out intelligence operations and other missions without the need to acquire new cameras.Ítem Diseño implementación y despliegue de un portal tipo intranet para la gestión de aplicativos del centro de operaciones de red (NOC) de una empresa de telecomunicacionesQuintero Peralta, Juan Diego; Plazas Nossa, LeonardoThe present document describes the development of an internship in a national telecommunications company.

Each real-time simulation platform establishes its own criteria and methodologies to carry out simulations of the systems under test, all of this to obtain faster and more accurate results, and reduce errors at the time of implementation of said circuits. In the research laboratory on alternative energy sources (LIFAE), of the Francisco José de Caldas District University, there is the real-time simulation tool Opal-rt 4510, which bases its operation on the hardware in the loop (HIL), and which is used for the modeling of power electronics systems, especially power converters, and whose tool has not yet been taken as much advantage as possible by university students, and That is why as a research project, the implementation and real-time simulation of power converters was carried out, with the objective of answering the question of whether it is possible to establish power converter models for academic purposes. , where said converter models were obtained from the comparisons of simulating each converter in real time in the CPU and in the FPGA of the opal, and where said models obtained from the comparisons could answer the question of whether it is possible that the models simulated in the opal CPU, are models that can be taken for academic purposes by students taking the subject of power electronics at the university, because the models of the converters simulated in the opal CPU are simulated with a much longer sampling time, compared to the very small sampling times with which a real-time simulation is done in the FPGA. The results obtained from simulating in real time, three types of power converters, show the great limitations that arise when a real-time simulation of a power converter is carried out, only using the Opal CPU or processor, to generate and process all the signals of interest in the circuit, given that it works with a longer sampling time, affecting the correct processing of the signals, and generating unexpected results, compared to those obtained using the FPGA, where the processing of the signals is a a higher speed, and the results obtained are those expected and real.Ítem Implementación de una red comunitaria Wifi en zonas periurbanas con sistemas basados en hardware y software libreCruz Parra, Jhon Sebastian; Espitia Clavijo, Mateo Andrés; Plazas Nossa, Leonardo; Suárez Guerrero, William FreddyLaw 2108 of 2021, known as the Internet Law as an essential and universal public service, aims to establish, within public communications services, access to the Internet as an essential one.

The proposed designs seek to reduce the size of radiant elements, without affecting parameters such as e ciency, directivity, gain and radiation diagrams.Ítem Diseño e implementación de un panel digital controlado por microcontrolador, adaptable a centrifugas analógicas de uso en laboratorios de pruebas biológicasSantamaría Bello, Jaime Ricardo; Camargo, Julián RolandoDesign of a digital panel, which allows controlling the running time and rotation speed of an AC single-phase motor, independent of its characteristics, applied in the control of an analogical centrifuge of biological laboratories (biological samples).Ítem Modelo de interacción social para agentes artificiales en la arquitectura mojanaPulido Mier, Héctor Andrés; Melgarejo Rey, Miguel AlbertoThis book brings together the development of a degree work carried out under the monograph modality in the research group LAMIC (Laboratory of automatic and computational intelligence) from mid-2014 to mid-2015, by an aspiring engineer electronic. From the interest in the area of artificial intelligence, the idea has arisen to carry out a simulation that carries with it the principles of collective intelligence. The work presented was basically done in order to include a model of social interaction between agents in an artificial agent architecture called MOJANA, developed by the professor and director of this work Miguel Alberto Melgarejo, Paula Andrea Villegas and Edwin Robert Pérez [16] . In order to carry out this work of degree it was necessary a detailed study of the complex systems and of the dynamics that of these systems emerge, since the key of these systems and why they can sometimes reflect certain aspects of the reality is the emergency that is given in them, when programming a pair of rules at the micro level to be able to see a result at the macro level. The systems of social interaction between agents are strongly linked to the concepts of systems of multiple agents and cellular automata, to collective intelligence and to the emergence of collective dynamics. To understand some of the dynamics explained here, it is necessary to deepen the study of the behavior of some animals such as ants and flocks of sheep, as well as flockings and artificial intelligence, without neglecting the study of some articles of the social sciences in which human behaviors are described that are part of the rules that each of the agents of the model of social interaction between agents that will be included in the architecture MOJANA.Ítem Reconocimiento de imágenes de componentes de circuitos eléctricos para su conversión a un archivo en formato Vhdl-AmsNiño Rodríguez, Juan Esteban; Torres Torres, Alejandro; Muñoz Quiñones, Gerardo AlcidesThis book describes the development of a tool for image recognition of electrical circuit diagrams containing elements such as resistors, capacitors, earth and different types of sources, and converts it to a file with the circuit description in VHDL-AMS format , with the aim of optimizing the process of electrical circuit design. In the first instance, data are collected that correspond to schematic images of electrical circuits, of which 80 percent were made by hand and 20 percent obtained from texts. It shows the treatment that is made to the input data that corresponds to the image of the electric circuit diagram, it goes on to explain the recognition system, starting with the characteristics and the requirements to be taken into account for the choice of these, In addition, the manual construction of decision trees is presented as a classification method for the identification of circuit elements, which has not been implemented in previous works for the recognition of electric circuits. Finally, the VHDL-AMS format was presented, which allows the description of the electrical circuit, with the elements identified and the connections between them. Once the description is obtained, the results of the implemented algorithm are evaluated.Ítem Acondicionamiento de un algoritmo de encaminamiento al sistema de comunicaciones en una microredLópez Mora, David Eduardo; Rodríguez Caballero, William David; Gaona García, Elvis EduardoThe future of energy in the world on the basis of climate change has an important passage with dependence on oil and other fossil fuels in terms of increased imports and rising energy costs. Having as an important requirement a complete and greedy answer. Greenhouse gas emissions and pollution reduce important capacities due to renewable energy, which in turn takes advantage of decentralized and local energy sources such as solar, wind, geothermal, hydroelectric and biomass resources. There must be a gain in the activation of employment, technological development and economic growth in terms of renewable sources immune to the volatility of fossil fuel markets. Today the environment has the highest concern for the temperature it handles on the planet and its elevation. This eventuality leads to technological advances with the use of energy and natural resources in the productive sectors. In the development of this project simulations are performed with two routing protocols for ZigBee networks such as AODV and DSR, under different network topologies in order to observe their behavior under these conditions and to be able to determine which is the most optimal for these conditions, it should be clarified that this simulations were performed lowered a context of an isolated microrred for rural areas. The NS2 tool is used to analyze the behaviors of the microgrids.Ítem Identificación dactilar a partir de un sistema difuso tipo 2 de intervalo basado en relaciones booleanasCoronado Donoso, Camilo Andrés; Medina Rincón, Laura Catalina; Muñoz Quiñones, Gerardo Alcides; Salazar Morales, OmarThis paper seeks to validate the previous hypothesis, in a first step developing the System design and implementation.
