Ítem Diseño y construcción de un dispositivo stand-alone para el diagnóstico de seguridad en redes inalámbricas(Universidad Distrital Francisco José de Caldas) Ocampo Abril, David Alejandro; Oquendo Massry, Elheim Nedith; Jacinto Gómez, Edward; Jacinto Gómez Edward [0000-0003-4038-8137]Telecommunications are a fundamental component for the functioning of modern societies, as large volumes of data are transmitted through them daily. Ensuring their security is very important because sensitive information such as personal and banking data is transmitted over these networks, the protection of which requires strict measures. To address this challenge, the development of a stand-alone electronic device that allows the evaluation of wireless communication networks is proposed. Its objective is to identify vulnerabilities in these networks and facilitate their correction, thus contributing to strengthening cybersecurity. To achieve this objective, a controller is first selected as the basis for the device's construction. A board is then designed and built to support all the system's hardware. Then, using Micropython as the programming language, the entire environment that will provide user interaction with the device is developed. Finally, reports are generated based on the results obtained. The results obtained demonstrate the effectiveness of the device through five tests in a controlled setting using population statistics techniques, achieving expected performance and within established parameters.Ítem Desarrollo de un sistema integral de gestión en corriente continua (DC) utilizando tecnología de comunicación por línea de potencia (PLC)(Universidad Distrital Francisco Jose de Caldas) González Contreras, Edwin Saúl; Negro Albornoz, Juan Diego; Mancilla Gaona, Giovani; Mancilla Gaona Giovani [0000-0002-2552-1836]The project developed a comprehensive direct current (DC) energy management system using power line communication (PLC) technology, aiming to optimize energy efficiency, reduce operating costs, and improve monitoring of critical processes. The system was implemented based on ESP32 microcontrollers, PZEM-004T multifunction sensors, and relay and contactor control modules, enabling real-time data collection and centralized and secure management of power distribution. Communication over the existing electrical grid, combined with the WebSocket protocol, facilitated efficient telemetry transmission, while the user interface was designed as a Progressive Web App (PWA) compatible with limited connectivity environments. The RESTful backend in Flask and the PostgreSQL database guarantee historical storage and reliable operation of services, adopting a microservices architecture that ensures fault tolerance and modularity. The solution demonstrates a sustainable, technically and socially applicable approach, enabling energy consumption monitoring, anomaly detection, and efficient power control in residential and community settings, offering an innovative alternative to conventional management and cabling systems.Ítem Metodología para la implementación de un control de acceso a la red WLAN utilizando una solución de NAC (Network Access Control) en la infraestructura física del Ministerio del Interior(Universidad Distrital Francisco José de Caldas) Varon Quiñones, Luis Fabricio; Mayorga Wilches, Cristian Alexander; Hernandez, Henry AlbertoThe purpose of this document is to design and develop a structured methodology comprised of seven phases for the implementation of a Network Access Control (NAC) system on the wireless network infrastructure of the Colombian Ministry of the Interior. The proposed solution aims to significantly improve security levels in WLANs (Wireless Local Area Networks) through centralized management of devices accessing the institutional network, applying authentication, authorization, and continuous monitoring policies. To achieve this, recognized standards such as IEEE 802.1X, the RADIUS (Remote Authentication Dial-In User Service) protocol, and integration with Active Directory are used, allowing the identity of devices and users to be validated before granting them access to network resources. The initiative arises in response to the growing need to strengthen security in corporate and institutional environments where the simultaneous connection of multiple devices is common, including personal devices of employees, contractors, and visitors (BYOD, Bring Your Own Device model). In the specific case of the Ministry of the Interior, a high turnover of connections was identified without verification of compliance with security policies, which represents a risk to the confidentiality, integrity, and availability of institutional services and data. The methodology developed ranges from the initial network diagnosis and evaluation of available NAC technologies to technical implementation, user training, and post-deployment evaluation through surveys and interviews. This methodological framework seeks not only to resolve the problems identified in the entity, but also to serve as a replicable model for other public or private institutions facing similar challenges in access control to their wireless networks. It is worth noting that the project had a total investment of $319,041,000, allocated to the acquisition of licenses and specialized services. The results obtained allow us to conclude that the implementation of a NAC system using a clear and sequential methodology contributes to greater visibility of connected devices, the reduction of unauthorized access, and the strengthening of institutional cybersecurity capacities.Ítem Sistema de tickets para la administración de activos de ti en la empresa Softtek renovation s.a.s.(Universidad Distrital Francisco José de Caldas) López López, Leidy Yurani; Bravo Martinez, Cristian Alfonso; Hernández Martinez, Henry AlbertoAt Softtek Renovation S.A.S.'s Bogotá headquarters, the IT department faced difficulties with the manual management of its IT assets. This process was carried out through informal requests, which generated delays in updating asset statuses in the Global Warehouse inventory software, in addition to errors and additional workload for the analyst in charge, making it difficult to track equipment assignments, de-assignments, retirements, and control of fixed assets. This need arose from the idea of developing a ticketing system to manage asset management. To this end, a web tool was designed using accessible technologies such as Google Apps Script, Google Sheets, HTML, Bootstrap, and jQuery, with the goal of building a functional, secure, and intuitive solution for both the IT team and employees. The system allows for recording requests for equipment assignment, de-assignment, retirements, and report requests, and stores all related evidence in the cloud. This significantly improves inventory control, reduces response times, and prevents data loss. It also facilitates processes such as internal and external audits, which previously represented a significant challenge. This project, which was developed in four months with an estimated investment of $8,356,000 COP, not only represents a technological improvement for the company. In short, beyond being a technical tool, this system seeks to transform the way technological resources are managed within the company, making work more efficient, transparent, and humane.Ítem Dispositivo IoT basado en un sistema de adquisición de imágenes para realizar análisis de la ergonomía por medio de la tecnología Sigfox(Universidad Distrital Francisco José de Caldas) Pinzón Cruz, Julian Esteban; Ospina Bocanegra, Crystian Camilo; Giraldo, Frank Nixon; Giraldo, Frank Nixon [000-0001-8407-1831]The following thesis project, titled “IoT Device Based on an Image Acquisition System to Perform Ergonomic Analysis Using SigFox Technology,” proposes the development of a communication system that functions as an ergonomic monitoring device. Given that musculoskeletal disorders account for 45% of reported occupational diseases in Colombia, and with the aim of reducing work absences and healthcare system costs associated with these injuries, a prototype was designed based on postural images captured through the Kinect V1 sensor. These images are transmitted to the backend platform via the SigFox network, chosen for its long range and low power consumption. The developed algorithm transforms joint coordinates, extracted from the images, into biomechanical angles and classifies the worker’s posture according to the OWAS ergonomic evaluation method. Through the graphical interface, the system enables the visualization, monitoring, and timely tracking of risk alerts for each employee, thereby facilitating the implementation of corrective measures to prevent permanent injuries. This approach demonstrates that the digitization of ergonomics is feasible even in environments with limited infrastructure, and lays the foundation for future applications of this type of communication system in surveillance and data monitoring processes across various industries.Ítem Estudio y diseño de intranet para cuatro laboratorios ubicados en el edificio Techne de la Facultad Tecnológica de la Universidad Distrital Francisco José de Caldas(Universidad Distrital Francisco José de Caldas) Mora Alarcón, Karen Tatiana; Martínez García, Leidy Vanessa; Montaña, Henry; Montaña Henry [0000-0003-0752-6315]This degree project presents the study and design of an intranet network for four laboratories located in the Techne building of the Facultad Tecnológica of the Universidad Distrital Francisco Jose de Caldas. The project was developed based on the specific needs of the academic programs of Control and Automation Engineering, Telecommunications Engineering, Telematics Engineering, Data Systematization Technology and Industrial Electronics Technology, which make use of the following spaces: Networks and Information Security Laboratory, Distributed Systems Laboratory, Telecommunications Laboratory and Automation and Control Laboratory. Currently, the Facultad Tecnológica does not have an intranet network infrastructure implemented in these laboratories, which limits the proper development of the practices required by the different curricular projects. This situation shows the need to design a solution that allows the fulfillment of the programmatic content of the subjects that require Intranet network connectivity for its correct execution. To carry out this project, various activities were carried out, including: the study of academic requirements, the collection of information through surveys of the coordinators of the laboratories, the analysis of the plans of the laboratories, the technical evaluation of the spaces, the collection of information on the network equipment available in the market, the validation of current regulations, the selection of appropriate software and, finally, the design of the Intranet network. As a result, an integral design of intranet network was obtained that responds to the current needs of the four laboratories located in the Techne building of the Facultad Tecnológica and that contributes to the training of future technologists and engineers of the Universidad Distrital Francisco José de Caldas.Ítem Diseño y aplicación de soluciones de ingeniería para proyectos del centro de investigación y desarrollo tecnológico de innovación aeronáutica de la fuerza aeroespacial Colombiana(Universidad Distrital Francisco José de Caldas) Oliveros Calderon, Jhon Sebastian; Gómez Gómez, Edgar Leonardo; Mahecha Monsalve, Cristian David; Gómez Gómez Edgar Leonardo [0000-0002-9544-0265]This internship was carried out at the Centro de Investigación y Desarrollo Tecnológico de Innovación Aeronáutica (CETIA) of the Colombian Aerospace Force (Fuerza Aeroespacial Colombiana), within the framework of the strategic projects led by the institution in the areas of automation, maintenance, and technological support for aerospace surveillance systems and unmanned platforms. The process was undertaken by two students from the Control Engineering and Telecommunications Engineering programs who, through practical integration into the center’s activities, applied and consolidated their technical knowledge in the real context of an institutional project. The internship was conducted over a period of six months, in a face-to-face modality. The central problem identified was the lack of adequate tools to perform safe and standardized technical maintenance on the Rotary Joint of the TPS-70/78 radars. These components are essential for radar operation, but their handling in the field—without the use of a specialized maintenance bench—has led to operational failures and risks of damage to critical and costly parts. In addition, a lack of operational documentation was identified in previously developed systems by the center, such as the solar runway lights system, as well as the need to conceptualize future solutions, including an automated charging and storage platform for UAS-type drones. These technological needs motivated the structuring of the internship as an opportunity to provide solutions through applied engineering. The proposed solution consisted of the design and implementation of an automated system for the Rotary Joint maintenance bench, integrating a control system and a wireless system for signal measurement at the rotary tip, aimed at detecting damage without interfering with its movement. Initially, a scale prototype was developed to validate the control model and, in parallel, technical manuals were prepared for the solar runway lights system, along with the exploration of a storage system design for drones. However, due to delays in the delivery of components by the institution, priority was given to the development of the maintenance bench as the main project of the internship. As a result, a functional system was implemented to control the three axes of movement of the bench, solving critical issues such as motor asynchrony. In addition, intuitive interfaces were designed, which, together with a wireless pressure measurement system connected through a LAN network and integrated into the platform, enhanced the overall operability of the setup. The prototype was validated on a universal PCB, and the design of a professional printed circuit board was completed for future manufacturing. The entire system was documented in technical manuals and commented code files, leaving a solid foundation for the continuity and full implementation of the project. In conclusion, the internship met the proposed objectives, strengthening CETIA’s technical capabilities and leaving behind a robust, well-documented solution for a key process in radar system maintenance. Furthermore, it highlighted the importance of modular planning, interdisciplinary integration, and clear documentation to ensure the sustainability and replicability of the technological solutions developed.Ítem Proyecto de emprendimiento para la creación de una empresa prestadora de servicios tecnológicos de Web Scraping, Analítica de datos e inteligencia de negocios(Universidad Distrital Francisco José de Caldas) Carreño Rivera , Andrea Catherin; Hernández Martínez , Henry AlbertoThis document presents an innovative business model based on the automation of data collection, analysis, and Business Intelligence of electronic product prices from the online marketplace Mercado Libre. Through the use of web scraping techniques, the aim is to facilitate strategic decision-making for microenterprises in the technology sector. It also seeks to optimize access to key information from the electronic market. The proposed strategy focuses on providing automated services for data extraction, transformation, and organization from the electronic marketplace, specifically targeting microenterprises in Colombia. This ensures efficient capture of information on price trends, product availability, and digital market behavior. Accordingly, the data analytics or business intelligence service to be offered to potential clients will support the transformative vision of small and medium-sized enterprises by enabling the identification and elimination of inefficiencies in business processes, as well as rapid adaptability to the market and its needs. The implementation of this business model makes it possible to provide a specialized e-commerce service that delivers quantitative and qualitative reports to support managerial decision-making. This specialized service for collecting and analyzing e-commerce data, combined with advanced data analytics tools, will provide valuable reports that strengthen decision-making processes in the electronic retail sector. The commercial and operational viability of the project is assessed, taking into account technological, regulatory, and financial aspects. This approach will make it possible to offer innovative solutions that enhance the competitiveness of microenterprises in the digital environment, providing accurate and up-to-date data for evidence-based strategic decision-making.Ítem Herramienta de cifrado para la ejecución de tareas colaborativas en sistemas de manufactura con múltiples robots en una red lan inalámbrica(Universidad Distrital Francisco José de Caldas) Franco Llanos , Kevin Stwar; Ortiz Torres, Michael Alexander; Hernández Martínez, Henry AlbertoCurrently, robotic systems controlled remotely via LAN networks are widely used in industry, automating repetitive processes or processes that pose a risk to people. The main challenge with these systems is that very few implement robust security, making them vulnerable to cyberattacks. To address this problem, a system was developed that allows the control and monitoring of a set of robotic arms in an industrial environment. The system was developed in Python and integrates libraries such as sockets and pyserial for communication with the robotic arms and Tkinter for the graphical interface, thus creating a user-friendly application that controls and interacts with the Mitsubishi RV-M1 robotic arm over a LAN. Additionally, the program uses an AES-type encryption algorithm to ensure security and reliability in the environment. Finally, a MITM attack is performed on the system, which aims to observe its behavior in two different environments: one without any encryption and the other where the system uses the encryption algorithm. This attack allows weaknesses in these systems to be identified, either by disconnecting them or even modifying the data sent from the application to the robotic arm. This underscores the importance of implementing effective encryption.Ítem Desarrollo e implementación de un banco de pruebas para la ejecución de ciberataques y análisis de vulnerabilidades al protocolo de comunicación modbus TCP/IP en sistemas SCADA Usando un entorno simulado(Universidad Distrital Francisco José de Caldas) Salazar Garzón , Edward Alexis; Riaño Robayo , Andrés Camilo; Espejo Mojica, Oscar; Espejo Mojica Oscar [0000-0002-0920-4531]This paper presents the implementation of a test bench focused on evaluating the security of the Modbus TCP/IP protocol, widely used in SCADA systems within industrial infrastructures. Given the lack of security mechanisms in the Modbus protocol, such as authentication, encryption, or access control, it has been identified as a serious vulnerability to cyber threats. This has made the protocol a primary entry point for affecting the quality of industries that use this protocol, which is widely used for communication between devices in industrial environments. It focuses mainly on the design and implementation of a test bench that allows the simulation of a controlled industrial environment in which cyberattack scenarios on the ModBus TCP protocol are reproduced. From this environment, different offensive techniques are executed on industrial communication in order to observe their impact on the integrity, availability, and operation of the system. These simulations make it possible to identify weaknesses in the protocol, demonstrate the operational effects of attacks, and assess the level of exposure of SCADA systems. To do this, we first conduct a study of the attacks to be carried out, based not only on the state of the art but also on a second investigation focusing on the ModBus protocol. Secondly, the simulation tools to be used for the test bench are chosen, where the environments must reproduce the protocol correctly. In addition, it must be possible to implement it in an environment where it is possible to demonstrate a system similar to reality, and in which clear comparisons of the effects of the attacks can be made. Finally, the simulation and execution of the attacks are presented, visualizing their implementation in the system and how the impact occurs once they are executed on the test bench. Through the analysis of the results obtained, an understanding of the system's behavior in the face of threats is generated.Ítem Traslado de los sistemas y canales de comunicacion de la UNP(Universidad Distrital Francisco José de Caldas) Timana Cepeda, Juan Vianey; Escobar Díaz, AndrésThe following article aims to explain the process for implementing the migration of the various communication systems and channels of the UNP government entity. It also aims to provide, through a conceptual basis, an analysis and/or proposal as a plan of recommendations for implementing a monitoring management platform for the entity's various communication channels. All of the above is framed within the best practices of strategies and policies for improving communication channels for communication systems and architectures in the Digital Transformation by the Ministry of Information and Communications (MinTic).Ítem Pasantía contratos interadministrativos 1579 de 2023 y 1468 de 2024 suscrito entre la Universidad Distrital Francisco José de Caldas (UD) y la Unidad Nacional de Protección (UNP) como apoyo técnico y administrativo realizando un exhaustivo estudio sobre el uso de optimizadores de redes LAN(Universidad Distrital Francisco José de Caldas) Rincón Murillo, Eduard Giovanny; Escobar Díaz, AndrésThis report documents the internship carried out as technical and administrative support for Inter-Administrative Contracts 1579 of 2023 and 1468 of 2024, signed between the Francisco José de Caldas District University (UD) and the National Protection Unit (UNP). This collaboration is framed within the UNP’s need to optimize its internal communications, which are crucial elements in fulfilling its mission to protect individuals and communities at risk. The internship focused on an in-depth study of the use of local area network (LAN) optimizers with the goal of improving the management and performance of internal communication systems within the UNP and other government entities in Colombia. The problem addressed stems from the growing demand for digital services and the need to ensure efficient, secure, and reliable communications within the UNP—an organization that handles sensitive information and operates in a high-risk environment. Network congestion, latency, and packet loss can negatively affect the operational capacity and responsiveness of the Unit. Optimizing the LAN network emerges as a necessity to ensure the smooth flow of information, support the entity's digital transformation, and enhance the experience of both personnel and the beneficiaries of its programs. The solution developed during the internship included a detailed analysis of LAN optimization tools and techniques, including protocol analyzers, key metrics (latency, bandwidth, jitter, packet loss), and Quality of Service (QoS) mechanisms. A state-of-the-art review of available hardware and software solutions on the market was conducted, evaluating their features, advantages, and disadvantages in governmental contexts. A cost-benefit analysis was carried out to determine the most suitable solution, and the successful implementation of the Bequant optimizer within the UNP was studied in depth. Additionally, support was provided for updating the UNP’s Disaster Recovery Plan (DRP), and educational material on LAN optimization was developed. The conclusions of this work highlight the feasibility and tangible benefits of implementing LAN network optimizers in government entities such as the UNP to improve the performance, efficiency, and security of their internal communications. A proactive approach is recommended for continuous network monitoring and optimization, considering solutions like Bequant based on rigorous cost-benefit analysis, along with ongoing training of technical personnel. The integration of these technologies is essential to support the UNP’s strategic goals of digital transformation and operational efficiency.Ítem Desarrollo de un modelo basado en machine learning para pronosticar el número de usuarios de televisión por suscripción para el departamento de Cundinamarca(Universidad Distrital Francisco José de Caldas) Barrera Estepa, Andres Felipe; Gallego Valcárcel, Fabian Andres; Pedraza Martínez, Luis FernandoIn Colombia, the landscape of subscription television has undergone significant changes due to increasing competition from streaming platforms and the country's geographical diversity. This phenomenon highlights the need for predictive models that anticipate subscriber behavior. In response, this monograph-based research project proposes the development of a machine learning model to forecast the number of subscription television users in the department of Cundinamarca. The methodology centers on the use of Meta’s (Facebook) Prophet library, renowned for its effectiveness in modeling time series with seasonal patterns and long-term trends. Prophet enables flexible adjustments of trend and seasonality components, making it particularly suitable for telecommunications data, where recurring variations over time are common. The choice of this tool is based on its ease of implementation, ability to handle missing data, and robustness against sudden changes. To build the model, historical data from the “Subscription TV Subscribers” Dashboard of the Communications Regulation Commission (CRC) was utilized. This dataset provides disaggregated information based on technology types (HFC Digital, Satellite, IPTV, among others) and geographical zones. Through exploratory data analysis (EDA), variable normalization, and feature selection, the dataset was prepared to feed the predictive model. The results not only provide projections for new subscriber numbers but also identify significant patterns in service subscription behavior. Key influencing factors include technology type, socioeconomic strata, and the geographical location of users. Additionally, the Prophet-based predictive model demonstrated solid performance, reflected in metrics such as Mean Absolute Error (MAE) and Root Mean Square Error (RMSE), successfully forecasting subscription television user trends for the next 6 to 12 months. In conclusion, the development of this model serves as a strategic tool for telecommunications operators and establishes a robust foundation for public policy design focused on digital inclusion and improved access to ICT services in Cundinamarca. Future research directions could integrate additional socioeconomic variables or explore hybrid models combining Prophet with Recurrent Neural Networks (RNNs) to further refine prediction accuracy. Let me know if you need refinements!Ítem Herramienta digital para el procesamiento de imágenes mediante un algoritmo de aprendizaje supervisado para la identificación de patrones de levantamiento de cargas y emisión de alertas tempranas de riesgo ergonómico.(Universidad Distrital Francisco José de Caldas) Pineda Casas, Maykol Steban; Camargo Ramírez, Brayan Jean Carlo; Hernández, Henry AlbertoDigital tool for image processing using a supervised learning algorithm to identify lifting patterns and issue early warnings of ergonomic risk. The system uses a webcam to capture images in real time and a supervised learning algorithm that analyzes the biomechanics of postures in a controlled environment. When inadequate postures are identified, alerts are generated that allow immediate correction, improving safety and reducing occupational risks. A problem in Occupational Safety and Health (OSH) lies in the difficulty of simultaneously supervising several employees in physical activities, especially where space is limited. Traditional observation methods are often biased and inefficient. This automated system optimizes supervision and facilitates the detection of risks in an objective manner. The proposed solution integrates technological devices, communication networks and programming based on supervised learning for the review of postures during lifting. As a result, it facilitates real-time decision making in controlled work environments. The implementation of this system represents an advance in the prevention of musculoskeletal disorders, optimizing occupational health and safety surveillance processes and enabling more efficient occupational risk management.Ítem Automatización y análisis en la gestión de proyectos usando power automate, power bi y power apps para manejo de big data, usando listas de sharepoint como base de datos para la integración de tecnologías de la información y las comunicaciones(Universidad Distrital Francisco José de Caldas) Hernández Cárdenas, Karinna Eyenith; Gómez Gómez, Edgar Leonardo; Gómez Gómez, Edgar Leonardo [0000-0002-9544-0265]This final internship report aims to clearly present the experiences, lessons learned, and the context in which the internship took place. The organizational, technological, and social contexts were key to its development. At the organizational level, Honeywell is a company whose main pillar is innovation, generating multiple technological solutions worldwide in specific business groups such as Industrial Automation, Aerospace Technology, Building Automation, and Sustainable Energy Solutions. Specifically in Colombia, it has pilot projects that contribute to the mitigation of greenhouse gas emissions. In the technological context, we find ourselves at a point where; to remain a competitive company in the market, it is necessary to leverage available technological tools such as Information and Communication Technologies (ICT). Socially, the company fosters an inclusive and collaborative environment where an innovative spirit is encouraged, along with the freedom to propose and develop solutions that significantly impact the organization’s performance. Despite being a leader in automation, small internal processes that collectively contribute to a major issue were identified: project document management is handled individually and in a decentralized manner by each Project Manager. This leads to errors, delays in document delivery, and even loss of documents, not to mention the lack of effective tracking and proper auditing mechanisms. To address this issue, a solution was proposed to automate and analyze project management by integrating ICT tools. As a result, a solution was developed integrating Power Automate, Power BI, Power Apps, instant communication systems such as Microsoft Teams and Outlook, and SharePoint. The total time required to run all flows is approximately 14 minutes and 48 seconds, with the longest flow being the initial one, since it includes actions that must be manually completed by the Project Managers. Its duration is around 12.23 minutes. The remaining flows—responsible for notifications, control, document synchronization, and project tracking—take nearly 3 minutes in total. However, some flows run simultaneously, and the number of flows that can be executed under Honeywell’s current license is unlimited. Thus, an extremely effective solution was achieved that enables the automatic creation of Microsoft Teams groups with unique names, with dedicated channels for Project Managers, Engineering, and HSE teams; the creation of folder structures based on Honeywell’s GPM standard; and the synchronization of documents with Power BI and Power Apps for monitoring and analysis, along with SharePoint lists for centralization. All of this enables audits by providing access to multiple KPIs and the ability to generate dynamic reports automatically.Ítem Herramienta digital ERP diseñada para configurar de manera centralizada los dispositivos que se encuentran en una red interna del Colegio León de GreiffUsaquén Otálora, Daniel; Vargas Acevedo, William; Hernández Martínez, Henry; Martínez Hernández, Henry Alberto [0000-0002-2323-0242]This document presents an SDN (Software-Defined Networking) solution based on the Netconf protocol, which integrates an ERP (Enterprise Resource Planning) model developed on the Odoo platform, allowing for the dynamic definition and management of a network topology. It features an SDN controller that facilitates resource management, device operations, and infra-structure automation. The project arose from the need to optimize the management and con-figuration of internal networks in academic environments where manual device interaction and the definition of network topologies are complex and error-prone. The development of an SDN application through the Odoo ERP is implemented to centralize the configurations of the devices on the network topology of León de Greiff School, located in a rural area of the municipality of Sibaté. The operation of this application module integrates a form-like view that captures the parameters to be modified by the network administrator, find-ing fields and computed states to validate the process. Internally, the application establishes the SSH connection with the device and translates the fields into network configurations using the Netconf protocol. This tool offers greater control and visibility of the network status and is supported by an easy-to-use interface that allows configuration and changes to be made in less time and effort. Its design optimizes resources to offer flexibility and scalability that is easier to implement. With this network improvement proposal, the School will achieve agile, secure, and efficient infra-structure management.Ítem Herramienta para el control de acceso basada en cifrado por desplazamiento, clave de longitud variable y elementos de tiempo e identificación(Universidad Distrital Francisco José de Caldas) Patiño Zawadzky , Ademir Jesús; Olivares Torres , Yamid Danilo; Hernández Martínez, Henry; Hernández Martínez, Henry Alberto [0000-0002-2323-0242]A tool for access control based on shift encryption, variable-length keys, and time and identification elements. This document addresses the problem of access control systems in residential buildings, which present significant security and efficiency gaps. In this context, efficiency refers to the system's response times, that is, the time it takes from the moment the user generates their QR code in the mobile application until access is verified and the door is opened.Today, common methods, such as physical cards or static access codes, present numerous vulnerabilities, such as duplication, theft, or unauthorized use.These limitations were resolved through the creation of a dynamic access control system based on QR codes, implemented through a mobile application. This system uses a proprietary encryption algorithm that produces dynamic keys using shift encryption and a variable key, providing a more secure and effective solution.The entire project includes the design of a database to store user credentials, the development of a mobile application that produces QR codes that are updated every 3 seconds, and the installation of a verification system using the FM3080 Hind scanner and the Raspberry Pi. This allowed the system to validate accesses in an average time of 2 seconds, seamlessly managing 80 consecutive accesses, improving speed and security compared to systems that use static codes.Ítem Implementación de un prototipo para localización de personas de la tercera edad utilizando una aplicación web y tecnología Sigfox(Universidad Distrital Francisco José de Caldas) Urrea Riaño, Andrés Fabian; Guzmán Méndez, Andrés Camilo; Giraldo Ramos, Frank Nixon; Giraldo Ramos, Frank Nixon [0000-0001-8407-1831]Cases of missing elderly individuals, particularly in urban areas, are frequently reported in Colombia. Many of these individuals suffer from degenerative diseases such as Alzheimer's, increasing their risk of disorientation and getting lost in public spaces. This situation generates significant concern for relatives and caregivers, who often lack efficient tools for timely location and assistance. In Bogotá, unlike other cities worldwide, there is no official system in place for locating missing elderly people. This highlights the need for accessible, socially focused technological solutions. To address this issue, a low-power, long-range tracking system was developed for elderly individuals at risk of disorientation. The system integrates a microcontroller with Sigfox connectivity and a GPS module to collect and transmit geolocation data to the cloud. The architecture was built using Microsoft Azure services, with serverless functions and an SQL database to process and store the data. A web application developed with React and Leaflet allows caregivers to remotely monitor the location of the elderly person from any internet-connected device. The prototype proved functional and efficient during tests conducted in Bogotá and the nearby municipality of Soacha. Sigfox technology showed good coverage and communication stability, and the cloud integration enabled effective data processing. The web interface was found to be intuitive and user-friendly for caregivers across different device types.Ítem Solución basada en software para el análisis de forma gráfica y gestión de los datos de cobertura 4G del repositorio datos abiertos Colombia de forma distribuida(Universidad Distrital Francisco José de Caldas) Uyaban Goyeneche, Michael Leonardo; Mejía Pinzón, José Luis; Hernández Martínez, HenryA software platform was developed for graphical analysis and management of 4G coverage data based on the information available in the Datos Abiertos Colombia repository. This solution responds to the need for accessible and effective tools to process and visualize large volumes of government data, traditionally dispersed and difficult to interpret. Through a data processing algorithm and a distributed architecture, the platform integrates standardized quantitative and qualitative metrics, allowing an accurate assessment of the quality and availability of the service. It also optimizes access to key information for mobile operators and contractors in the sector, facilitating the identification of gaps in coverage and supporting strategic planning and decision making in the telecommunications field.Ítem Implementación de un modelo predictivo basado en redes neuronales recurrentes en una aplicación para gestionar mantenimiento predictivo de equipos de gases arteriales disponibles en unidades hospitalarias(Universidad Distrital Francisco José de Caldas) Ramos Almanza, Paula Andrea; Saavedra Saavedra, Sneider; Hernández, Henry AlbertoThe medical device market has grown rapidly in recent years. As technological trends in the healthcare industry focus on improving human well-being, it is currently unknown exactly how many different types of medical devices are used and exist worldwide. However, in the Region of the Americas, emerging medical device markets are highly significant; with few exceptions, countries import more than 80% of their medical devices. Given this situation, it is essential for countries to prioritize patient safety and ensure access to high-quality, safe, and effective medical devices [1]. In this context, it becomes evident that reducing the high downtime of biomedical equipment in hospital units—caused by failures or maintenance—is crucial. These interruptions often lead medical personnel to make decisions based on patient symptoms and personal experience, rather than on reliable laboratory test results, increasing the likelihood of misdiagnosis.Therefore, this project proposes predicting potential failures in arterial blood gas biomedical equipment through the use of ICTs, specifically by implementing Recurrent Neural Networks (RNN) trained on data such as date, device serial number, type of service, city, failure, and solution—recorded by expert engineers through a standardized form. This document presents a methodological design for the proposal to be developed over a 12-month period, with an estimated cost of $9,662,000, under the monograph modality and aligned with research areas in industrial automation and ICT management. The project will be implemented at the Faculty of Technology of Universidad Distrital Francisco José de Caldas and directly supports the healthcare and ICT sectors.
