    Sistema de riego por goteo telecontrolado mediante una funcionalidad de pronóstico basada en el modelo hídrico de la FAO
    (Universidad Distrital Francisco José de Caldas) Torres Matallana, Ana Maria; Toro Vaca, Jeison Santiago; Hernández Martínez , Henry Alberto
    This project focuses on the implementation of a drip irrigation system prototype integrating the FAO's water balance model, designed for the cultivation of Diacol Capiro potatoes. The goal is to develop a control mechanism that optimizes water use based on predictions and monitoring of real soil and environmental conditions through web visualization. The project methodology was divided into four key phases. Initially, the physical structure of the irrigation prototype was built, then sensors were programmed and calibrated, later, the sensors were implemented on the Raspberry Pi to enhance control and facilitate the integration of the water balance model, and finally, the water balance model was implemented for the comprehensive operation of the project. The main result of the project was the ability to activate the irrigation system of the prototype at precise moments and with the exact amount of water in collaboration with the water balance model's ability to determine the crop's water needs. It was also achieved, through continuous analysis of data generated by the system, to keep a record on a web page. The implementation of a telecontrolled drip irrigation system demonstrates efficient water use, promoting sustainable irrigation practices. The integration of sensor technologies and predictive models improves water management in crops such as Diacol Capiro potatoes, ensuring efficient and sustainable production.

    Thomas Information Management Technical Services is a company dedicated to the processing and custody of physical and digital documents for private and government entities. One of the company's clients is the Banco Agrario de Colombia, for which the company developed SIGDOC, a custom software that allows bank officials to review customer documentation for credit studies. The SIGDOC application consists of various services such as databases, reporting, file sharing, proxies, email, applications, among others, which run on servers with operating systems like Windows Server, Linux Centos 6, Linux Centos 7, and Ubuntu. These servers are installed in different data centers that interconnect with the Banco Agrario's private network. It is essential for Thomas Information Management Technical Services to have monitoring systems for these servers that allow it to respond to potential incidents of SIGDOC system unavailability before they occur and affect queries and system performance. Being able to monitor the system allows the entire technology staff to act promptly in the face of any incident. To facilitate the monitoring task of the technology area, the CACTI tool was installed on an Ubuntu server. This tool allows monitoring the status of the servers' technological resources and sending alerts to the technology area staff whenever a saturation occurs on any server using a Zimbra mail server that was also installed on an Ubuntu operating system and parameterized to be interconnected with the monitoring tool. The monitoring tool, together with the alert system, allowed the technology staff to act promptly in the face of any saturation or unavailability incident of the SIGDOC system modules, thus guaranteeing the service level agreements (SLAs) that the company has contracted with the Banco Agrario and improving the quality of service and perception that bank officials have of the SIGDOC information system.

    This monograph is a study carried out for the design and manufacture of a helical antenna, and the use of a radio frequency amplifier in order to improve the operational coverage conditions for a Remotely Piloted Aircraft System of the quadcopter type, which seeks to extend the coverage of the telemetry transmission of the radio control used for its operation in flight. This work focuses on two topics that are related to the antenna design. The first one explains the theory related to the antenna frequency operation, the type of polarization of a helical antenna, its radiation pattern, the operating field region and the impedance associated with the antenna design. Likewise, we worked on the parametric simulation of the antenna in the CST Studio software, thanks to this simulation we studied the variations of the spiral separation and the diameter of the antenna, which are based on the design of the real antenna. The second section focuses on the construction and fabrication of the helical antenna. In this section we can detail the corrections to its impedance with the Smith chart, since in this way it is possible to obtain an improvement in the propagation efficiency and improve the results in the S11 parameters. Along with the improvement of the operational coverage, a Radio Frequency amplifier is selected to improve the dBm of the ground transmitter. This component is compatible with

    López Cárdenas, Andrés Rodrigo; Rodríguez Rodríguez, Cristian Daniel; Hernández, Henry Alberto
    The issue of insecurity and risks to which bicycle users are subjected with the theft and loss of bicycles is still a difficulty that continues to occur on a daily basis. Currently, the use of technological means seeks to solve a fragment of this problem, but cases such as the poor implementation of IoT technology makes such solutions are not sufficient, since it fails to have such a scope that incorporates the needs that help the end user after a theft event occurs, for this reason we develop a sensor and security tracking system for bicycles, which can be monitored remotely, establishing a wireless communication through IoT technology with the GSM/GPRS SIM 800L module. The data are captured by means of a GPS sensor V.KEL G5LF, these variables such as latitude, longitude, speed, altitude, satellites, are controlled by an ESP32 microcontroller, which once transmitted records them in a Firebase server to be displayed through an Android mobile application where you can interactively view the data and the route taken by the device. Through the tests carried out in different environments, the remote device developed enables an adequate process in the reception of data, its portable, useful, practical and low-cost design favors its implementation, offering itself as a possible solution due to its economy, additionally, it offers adaptability at the time of assembly on the bicycle without interrupting its operation. Faced with these environments, the development of the application connects the user to a light and intuitive digital resource, in order to facilitate its use and see the tracking of the route and variables in a stable way. Now, the use of IoT technology as a support for the system, allows to incorporate it in everyday environments to continue expanding its integration, taking advantage of its deployment and technological advancement. Finally, the implemented system contributes to develop devices that become affordable tools by providing real-time monitoring, providing information for the recovery of the bicycle, which helps to continue attacking the problem of bike-user safety and vehicle loss, in addition to being an alternative solution and continue promoting the use of clean and sustainable mobility.

    Algoritmo de diagnóstico para evaluar parámetros de calibración en los sensores IoT Xovis con el propósito de sistematizar el proceso de calibración en la empresa Followup, basado en procesamiento de imágenes
    Castro Romero, Nicol Stacy; Barón Diaz, Angie Catalina; Hernández Martínez, Henry Alberto
    FollowUp Company provides a people counting service using Xovis brand IoT sensors. To ensure the accuracy of the service, a periodic calibration process of the sensors is carried out. This process is based on analyzing the margin of error between people entering and leaving the monitored area. If this value exceeds 5%, the Xovis API is accessed to analyze the sensor's real-time image. The analysis utilizes height maps, stereo image maps, start-stop maps, and an old image of the sensor to determine whether calibration is necessary, if there is another issue at the sensor's location, or if another intervention is required. The Python library OpenCV is used for image processing. The algorithm is hosted in a script that takes the MAC addresses of the sensors as input and outputs a new Excel list of sensors that require calibration.

    Malambo Moreno, Jeisson Alexander; González Amortegui, Mateo; Hernández Martínez, Henry Alberto
    In this paper, the problem of pet abandonment in Colombia is addressed, where it is estimated that around 3 million dogs and cats are in a street situation [1]. To address this worrying situation, a website has been developed with a focus on the geolocation of these pets to facilitate the pet adoption process. This approach seeks to offer an alternative to conventional mobile applications, allowing users to search and publish pets using a geolocation system that adapts to the user’s radius of action. In order to provide a solution to connect needy pets with homes or people who want to have a new member in the family and thus reduce the number of animals abandoned on the streets. The application is developed in a VLAN architecture based on a client-server scheme of 3 layers, it seeks to implement the creation of a graphical user interface based on a Progressive Web APP (PWA), and the evaluation of the performance of the proposed model. The research question guiding this project is: What are the optimal parameters that allow the PWA to be an effective tool to help homeless pets virtually?

    Implementación de un sistema de predicción de medidas LTE utilizando la tarjeta de desarrollo Zedboard y Machine Learning
    Porras Garzón, Nicolás; Gómez Pérez, Helmunt Alberto; Pedraza Martínez, Luis Fernando
    The different conditions under which LTE mobile networks operate make it necessary to establish strategies that allow the interpretation of different variables involved in their design, construction, deployment and operation. One of these key variables within the LTE mobile context are the power ratio and signal quality measurements, RSSI, RSRP and RSRQ. The main methods used to quantify these measurements in a physical environment, beyond on-site measurement, may be propagation models, however, in addition to the mathematical construction involved in their use and implementation, they are not really tools that forecast or predict signal behavior in a specific environment, clearly showing a need that has not been adequately met in this area. In this perspective, a viable option to the prediction of these measurements are predictive models, but if in addition to the problem of predicting itself, the context of working with mobile equipment and outdoor environments is added, it makes sense to route these prediction models in a device that offers portability in some way. FPGA-type reprogrammable boards or embedded systems provide a moderate amount of processing resources that, in applications such as those required for this problem, turn out to be sufficient to implement predictive models. Thus, ZedBoard, together with a dedicated operating system that supports programming languages specialized in Machine Learning such as Python, is a suitable candidate for code prototyping in this field. We propose then the design and execution in an interactive Python code environment, such as Jupyter Notebook, the development of three predictive models based on the algorithms of Linear Regression, Polynomial Regression, and Random Forests, respectively, using as reference the real measurements taken from an LTE base station on a mobile terminal. Additionally, a predictive model based on Recurrent Neural Networks is developed outside the ZedBoard. The purpose of this is, firstly, to diversify the alternatives in terms of Machine Learning algorithms used; and also, to technically support that the effectiveness and usefulness of the use of other embedded models that apparently do not have the necessary power in this type of applications, are also capable of offering complete solutions in an area in which they are not usually considered. At the end of the design and deployment on the test data, the predictions made by each model are conclusive and reaffirm the real possibility of implementing predictive models based on Machine Learning techniques in embedded systems, and within the context of mobile telecommunications. For this specific problem, the Random Forests model proved to be far superior and adequately adapted to the characteristics of the LTE variables analyzed with an error margin of less than 6% in any case, even above the Recurrent Neural Network model that was not executed in ZedBoard, allowing to deduce that there are other options in relation to the prediction of mobile signals and offering new alternatives to the classical methods of planning, dimensioning and characterization of an LTE cellular network.

    Análisis estadístico y pronostico para el servicio de internet móvil de los operadores en Colombia usando machine learning para determinar el número de abonados y su portabilidad
    Castillo Caranton, Luis Felipe; Flórez Salazar, Miguel Ángel; Hernández Martínez, Henry Alberto; Pedraza Martínez, Luis Fernando
    Mobile operators in Colombia and their offered services collect a large amount of information regarding the variables of each service, as is the case of mobile internet, which today is offered by all operators in prepaid and postpaid plan modalities. The dynamics of supply and stability in the market that each operator has is linked to the characteristics of their plans and the constant change that each one presents monthly. This is why for entities such as the Communications Regulatory Commission (CRC) that owns and collects this data, it becomes necessary to understand the influence and dynamics of these conditions and their changes over time. The Postdata platform, managed and constantly updated by the CRC, collects various information from mobile operators in Colombia. Within this is the history of subscribers, portability and rates, where each one corresponds to different periods of time since its collection and/or update. This data is publicly accessible, so it is possible to consult and download it at any time. With this, it is possible to carry out and implement a statistical analysis that demonstrates the current conditions and the historical change of these variables in reference to each operator and its plan modalities. The realization of this analysis and respective forecast is framed through an institutionalized research project between the Francisco José de Caldas District University and the CRC endorsed by Minciencias through call 908-2021 (“New knowledge, technological development and innovation for the strengthening of the Information and Communications Technologies (ICT), postal and audiovisual content sectors. In this project, we seek to give greater visibility and importance to this data through a graphical user interface in which statistics and Machine Learning (ML) tools and techniques are integrated to generate results that provide a detail of the competition and dynamization of the variables in the different operators in the country.
