Ítem Modelo de navegación basado en georreferenciación interior para la Universidad DistritalSánchez León, Ludwing Alejandro; Daza Corredor, Alejandro Paolo; Daza Corredor, Alejandro Paolo [0000-0002-3089-1233 ]This research proposes a navigation system using BLE technology, which determines the position of an user based on the power of the signal received from a series of transmitters which are located in fixed locations. To interact with the system it was created a mobile application using flutter and firebase. The relation between the received signal strength and the distance to certain transmitter it was created a polynomial model as an alternative to the log distance path loss model that increases the accuracy of the calculated distance, specially for distances lower than three meters and greater than eleven meters. Finally, it was found that the min max trilateration method has better accuracy than the traditional trilateration method to determine the position from the distance to the reference nodes.Ítem Diseño e implementación de una herramienta para information technology service managementCastro Tovar, Juan David; Gutierrez Castellanos, Juan Felipe; Flórez Cediel, Oscar David; Flórez Cediel, Oscar David [0000-0002-0653-0577]This project shows an ITSM solution, tailored to the needs of a company large-scale telecommunications, particularly the deployment and configuration of the GLPI tool adjusted to the requirements requested in the company, this process was achieved based on clear objectives represented in phases, which facilitated its execution and success, it designed the configuration, implementation and deployment workflows, managing to discover sources of static inventory information as well as those of dynamic or equipment inventory operating in the network, different data extraction mechanisms were proposed and a automated process for the extraction of data in a massive way, with which the process was improved asset treatment internally, finally, a server was implemented that hosts the tool, in such a way that it would be accessible to any type of user connected to the network corporate.Ítem Proyecto de certificación de la norma ISO 28000 en la empresa ST Logistic ZFB S.A.SJara Reyes, Johann Steven; Gómez Paredes, Juan Carlos; Gómez Paredes, Juan Carlos [0000-0001-5000-8121]In a world where there is constant technological development and in which a high percentage of operations and services have been digitized, the fact that a large part of the operations are done virtually, partly forced by external situations such as a pandemic, the importance of information security and computer security is strengthened, to avoid the now known cybercrimes, which can include situations such as theft / identity theft, information theft, hacking, among others; personal information becomes an even more important part of people's lives and, in the case of this document, companies.Ítem Diseño y construcción de un modelo de sistema de calidad para el área de aseguramiento de red de una empresa de telecomunicaciones bajo la recomendación de la norma COPCNovoa Amezquita, Hector David; Plazas-Nossa, Leonardo; 0000-0002-2223-9886A quality system model within a company seeks to increase the effectiveness of a specific area or the company in general to develop some high impact activity for the operation being carried out. In this project the objective was to show in a dynamic and interactive way the effectiveness that the Network Assurance area is having when informing customers constantly about the status of the failure report made on any service contracted with the company, in order to meet quality standards and demonstrate the company's interest in satisfying customer needs. Initially the idea was raised, proposing to evaluate the time that engineers are having when keeping the customer informed during the validity of a report made by the same, while the corresponding verification and configuration activities are performed to provide a solution to the reported. After this, the necessary data was collected with the help of the engineer in charge within the company and a limited database was consolidated, this in order not only to evaluate the times mentioned according to the recommendation of the COPC standard which focuses on customer experience, but also to arrive at an average that indicates the performance that each engineer has had in all cases handled within the limit of months that covers the database used and even to analyze the quality that the group of engineers in the area had with a particular client. Having the proposed statistics and configured the database in the application where it was desired to visualize all the information, it was possible to generate additional analysis regarding the recurrence of reports, areas that are usually more affected in the country for controllable or uncontrollable reasons by the company in order to propose preventive actions that greatly reduce the recurrent failure reports.Ítem Implementación, instrumentación, monitoreo y control de un invernadero a escalaAriza Pinilla, Andrés Camilo; Corredor Ramírez, David Gerardo; Ovalle Martinez, Diana Marcela; 0000-0002-3650-4273The paper describes a capstone project focused on the implementation, instrumentation, monitoring, and control of a scale greenhouse.

Short-term weather forecasting is an extremely complex field that has been the subject of exhaustive study in recent years. Advances in measurement and data capture systems, as well as in computational capacity, have made possible a remarkable improvement in the accuracy of short-range weather forecasts. This progress is having a significant impact on the way individuals and communities anticipate and prepare for weather conditions. The automated learning methods selected for this study encompass both fuzzy systems and neural networks. Among the fuzzy systems, simple genetic algorithms (ANFIS), evolutionary algorithms (DE) and fuzzy system random search algorithms (random search) were implemented. On the other hand, in the field of neural networks, FeedForward networks, LSTM networks and BILSTM networks were used. All the implementations were carried out using algorithms developed in the MATLAB programming environment. The evaluation of the implemented methods was carried out by analyzing various performance indices, such as prediction of change in direction (POCID), pearson correlation coefficient (r), nash-sutcliffe efficiency (NSE) and root-mean-square deviation (RMSE). The results obtained reveal significant findings that underscore the need for further research in this area. This paper presents a solid starting point for understanding and improving precipitation prediction methods in Bogotá, thus contributing to the advancement of research in climatology and machine learning applied to unpredictable and complex meteorological phenomena.Ítem Gestión de llaves criptográficas orientado a un respaldo seguro y su recuperación en redes distribuidasPeña Umaña, Santiago Adolfo; Castañeda González, Juan Sebastian; Pava Diaz, Roberto AlbeiroIdentity management (IDM) models have been shifting in focus as new approaches become more widespread in the digital world. The first model has a traditional centralised approach, charged with the control and privacy of personal data in identity management, whereas the more recent model has a self-governed or self-sovereign identity approach, as a result of an increased awareness of the importance of personal data. The quest for autonomy proposed in the newer model brings with it the management of passwords, which brings with it a number of features that are positive for the user, such as privacy and security of credentials. However, such control also brings with it an added responsibility, since human error has a higher level of impact on the management of autonomous keys, since the loss of the key can result in the impossibility of accessing the digital wallet, and consequently, the information stored in it. To solve this problem, a strategy and the development of a functional prototype, supported by distributed logging techniques, are proposed. The design and implementation of a functional prototype for the management and recovery of cryptographic keys through smart contracts in distributed networks is described. A Shamir secret sharing scheme is identified as suitable for splitting user keys and distribution is facilitated through transactions specified by smart contracts in the Ganache blockchain network. The restoration process reads the distributed segments using a function specified in the smart contract and reconstructs the segments by selecting Newton's polynomial interpolation method.Ítem Uso de la conjetura de collatz como estrategia para el encendido de conversores DC-DCRueda Mendez, Ronny Alberto; Guacaneme Moreno, Javier Antonio; 0000-0002-5480-8588In the present investigation, we sought to propose the Collatz conjecture and its parity as a strategy for powering up DC-DC converters.

The banking sector has not been oblivious to this generational change, as it has gone from keeping financial records manually in cumbersome and dangerously vulnerable books to having sophisticated systems that allow any type of transaction to be performed at a click away, guaranteeing the integrity of the information and safeguarding the money from unscrupulous people. However, the infrastructure required to meet this need must be constantly evolving and expanding as more and more users join the digital commerce trend. In 1999 the Colombian government decreed law 527, which defines digital commerce as any commercial relationship, structured from the use of any type of information sent, received or stored by electronic, optical or similar means (Internet, e-mail, etc.). Thanks to the expansion of this new type of commerce, the opportunity is generated to perform the usual financial operations in an easier way, using digital channels. Under this scenario, it is necessary to regulate these technologies, used by market participants; for the national case, these functions were delegated to the Financial Superintendence, which establishes the minimum operating parameters of the systems as well as the useful life of the same in order to ensure the rights of consumers and the availability and security of services. In 2007 the Financial Superintendence issued the external circular 052, entitled "Minimum security and quality requirements in the handling of information through media and distribution channels of products and services", in which it orders all financial entities to implement information management and security systems, This is in order to mitigate the risk of loss, modification or theft of user information due to the use of obsolete technologies or technologies that are not supported by the manufacturers. That is why this project aims to comply with the regulations of the Superintendence of Finance, migrating the core banking currently used in Banco P, also providing another series of benefits for it.Ítem Arquitectura de un sistema de multiplexación de sensores basados en redes de difracción de Bragg para monitoreo del oleoducto Caño Limón-CoveñasSánchez, Juan Diego; Pulido, Julieth Daniela; Puerto, Gustavo Adolfo; 0000-0002-6420-9693In this degree work, a monitoring system based on Bragg diffraction gratings is proposed to constantly and in real time monitor the Caño Limón-Coveñas oil pipeline.

This methodology enables the application of PMI standards to optimize project management and ensure successful project delivery within the specified time frame.Ítem Robot terrestre para exteriores con navegación autónoma basado en fusión sensorialVillanueva Serna, Emily Angélica; Mora Cortes, Michael Steven; Jutinico Alarcón, Andrés Leonardo; Jutinico Alarcón Andrés Leonardo [0000-0001-9146-9637]This research project focuses on developing an Ackerman kinematic ground robot for autonomous outdoor navigation based on sensor fusion navigation techniques, which are intended to reach a desired point. These techniques will focus on the use of stochastic estimators such as the extended Kalman filter (EKF) and trajectory tracking algorithms such as Pure Pursuit, which allow estimating the robot's position in real time and correcting its trajectory while heading to a desired point in such a way that the final position error is minimized. The sensors used for position and orientation estimation are: IMU (inertial motion unit), magnetometer and encoders, which provide relative motion-dependent measurements. On the other hand, the data from the sensors are obtained and processed through a small computer called Raspberry Pi 3 which in turn is implemented through the Python programming language algorithms for autonomous navigation and the generation of the actuator control signals is performed, for this type of robot the actuator used is a servo motor that controls the direction. All components are mounted on a chassis with Ackerman kinematics. The tests are performed on a level and obstacle-free terrain. Finally, the results of the position estimated by the Kalman Filter are compared with the position estimated by the Tracker software, thus obtaining a prototype capable of reaching a target zone of radius 60 cm in paths of up to 24 m, in addition to estimating trajectories with an RMSE error of up to 0.84 m.Ítem Diseño de una aplicación móvil para determinar niveles de oxígeno en la sangre y frecuencia cardíaca, a través de señales biopotenciales PPGArias Castellanos, Heidi Nathalia; Bolaños Galindo, Laura Juliana; Camargo López, Julian Rolando; Camargo López, Julian Rolando [0000-0003-3483-1884]This work presents the practical implementation of knowledge in bio-engineering and mobile application development, contextualized in a particular reality in Colombia. In this work, the analysis and processing of Photoplethysmographic (PPG) signals is performed in Python, connected to a mobile application by means of Firebase. The error associated with the signal processing was calculated from the repository "Oximetry phone cam", obtaining an average cumulative error of 4.10% in blood oxygen saturation values, in measured ranges of 100% - 85%, and the average cumulative error of 4.58% in heart rate in a range of 52bpm -96bmpÍtem Procesador digital de señales aplicado en sistemas de refuerzo sonoro implementado en una placa comercial de bajo costoLópez Casallas, Gabriel Enrique; Ascencio Silva, Juan José; Camargo López, Julián Rolando; Camargo López, Julián Rolando [0000-0003-3483-1884]This paper presents the design of a device aimed at correcting disturbances in a sound reinforcement system. The fundamental component of this system is the speakers, which are typically designed for ideal conditions such as spatial location and acoustic reflections in a specific venue. However, physical variables such as temperature, dimensions, phase cancellations, and construction materials significantly affect their performance. To mitigate these issues in the original signal, processes such as equalization, compression, and delay are employed. Currently, these processes are integrated into a single system known as an "integrated speaker management system." However, the high cost of these systems hinders their implementation in budget-constrained installations, which often face significant challenges in this regard. This paper aims to present the design of a device featuring stereo analog audio input and two processed audio output channels to effectively support sound reinforcement systems.
