Ítem Reference Model of Appropriation of Digital Technologies for Learning in Higher Education Institutions(Universidad EAFIT, 2024) González Franco, Germán Alberto; Tabares Betancur, Marta Silvia; Tabares Betancur, Marta SilviaIn the digital age, technology for learning has promoted a constant evolution in educational dynamics. This leads higher education institutions to rethink themselves with new styles or models to achieve the adoption and adaptation of technologies in new academic environments. However, very few frameworks for acquiring and deploying digital technologies for learning that integrate such technologies. This paper proposes a model to guide the appropriation of digital learning technologies in the Higher Education Institutions. To achieve it, initially, an exploration of the literature concerning the appropriation of digital technologies in the context of learning for higher education institutions was made, and then, data was collected that allowed us to understand the state of the appropriation of digital technologies for learning; Thus, a model with interrelated components for appropriate digital technologies for learning was designed. It included metrics that allow us to know the level of appropriation. Finally, the authors validated its relevance to digital technologies for learning projects among stakeholders through their strategic guidelines for appropriation in different academic contextsÍtem Utilización de desechos textiles para la industria de la construcción(Universidad EAFIT, 2024) López Cadavid, Ángela María; Zapata Múnera, Abraham UrielÍtem Efectos del proceso de integración de la biofilia y la arquitectura en el bienestar de las personas en el Valle de Aburrá(Universidad EAFIT, 2024) Cadavid Suárez, José Mateo; Zapata Múnera, Abraham UrielÍtem Guía evaluativa para el diseño sísmico de estructuras de concreto(Universidad EAFIT, 2024) González Arias, Diego Alejandro; Botero Palacio, Juan CarlosÍtem Cálculo de líneas de influencia en vigas de Timoshenko utilizando funciones de Green(Universidad EAFIT, 2024) Ovalle Contreras, Raúl José; Molina Villegas, Juan CamiloÍtem Evaluación patológica de las estructuras que atraviesan la quebrada la volcana en la ciudad de Medellín(Universidad EAFIT, 2024) Fuentes Nieves, Jeison Arley; Botero Palacio, Juan CarlosÍtem Patrones de sostenibilidad : gestión de capacidades para apalancar el crecimiento de pymes en entornos VUCA(Universidad EAFIT, 2024) López Arias, Christian; Guarín Grisales, Álvaro de JesúsThis research explores factors that generate unsustainability in Colombian small and medium-sized enterprises (SMEs) in VUCA (Volatility, Uncertainty, Complexity and Ambiguity) environments, through a mixed approach that combines quantitative and qualitative analyzes from surveys of entrepreneurs and corporate leaders with experience in innovation, business, strategy and organizational competitiveness. The results reveal that factors such as lack of access to financing, intensified competition, changes in the market, macroeconomic fluctuations and technological obsolescence significantly affect and put business sustainability at risk, limiting the ability to adapt to changes in the business environment. Research suggests that companies must constantly monitor their environment and business model to ensure desirability, feasibility and viability, which are critical to long-term sustainability. Strategic ambidexterity becomes a fundamental activity to generate continuity opportunities for businesses, highlighting the importance of using mechanisms that diagnose and enable the efficient exploitation of existing business models from the understanding of sustainable patterns such as desirability, feasibility and viability and the exploration of new models to face the challenges generated by highly uncertain environments that constantly threaten processes, products and businesses. Patterns such as continuous innovation and adaptability stand out, essential to maintain competitiveness in volatile, ambiguous, complex and highly uncertain environments.Ítem Modelo de excelencia operacional sector industrial colombiano(Universidad EAFIT, 2024) Ochoa Naranjo, Juan Esteban; Ramírez Echeverri, Sergio Augusto; Ramírez Echeverri, Sergio AugustoOperational excellence models have been implemented by various companies worldwide to guide their organizational procedures, to be able to last over time and guarantee their profitability. For the Colombian case, no model of this type has been documented to promote operational excellence in national companies, this work seeks to carry out a bibliographic review on the relevant models of operational excellence in the industry and supported by the judgment of experts, to develop a reference model for the search for operational excellence, presenting companies with a model with their respective improvement tools and indicators, on which they must work to focus on the company's overall results, seeking to maximize sales and not on local efficiencies, allowing them to look at the organization with a holistic approach and understand the relationships between the different areas and how they work generate synergies in the organization to achieve the main objective of every company: to generate greater profitability through sales. Here we will make a compilation of the different models most used nationally and internationally, which will allow us to make a tool that allows companies to identify the current position of their strategic state. This model will also be used as a diagnostic and evaluation tool to review the degree of maturity that a company has around the search for operational excellence, where opportunities for improvement will be found and, how to iterate on the model and generate systematic continuous improvement for companies in the industrial sector in Colombia.Ítem Efecto de la temperatura en la reducción del tiempo para la producción de crudo, destilado y aislado de CBD(Universidad EAFIT, 2024) Rojas Londoño, Johan Sebastián; Ramírez Echeverri, Sergio AugustoÍtem Asset management of railway systems considering the track-vehicle interface(Universidad EAFIT, 2024) Araque Argüelles, Diego Alonso; Castañeda Heredia, Leonel FranciscoÍtem Desarrollo de prototipo de prótesis ajustable multiusuario de miembro superior(Universidad EAFIT, 2024) Chávez Castaño , Juan Camilo; Guarín Grisales, Álvaro de JesúsThe World Health Organization estimates that around 1.3 billion people in the world live with disabilities, and in Colombia it is estimated that there are 1,298,738 people with disabilities, 18.5% of them affected in the upper limbs. Amputation in this area negatively impacts the patient's independence, functionality, and emotional state. To address this problem, a study was carried out based on a projective methodological cycle to design an adjustable and universal prosthesis for cases of amputation of the middle third of the forearm or the entire hand. During the research, a prosthesis prototype was created that was easy to fit and suitable for daily activities, with a comfortable and secure fit between the socket and the residual stump. However, the need to soften the coupling between the terminal device and the prosthesis was identified due to difficulties in its manipulation. Damage to the ratchet guide was observed and the need for adjustments to the suspension device was detected for users with greater muscle mass in the biceps. The simulations showed that the socket is safe, but the terminal device requires redesign due to evident structural flawsÍtem Análisis comparativo de cargas de viento : evaluación de la norma NSR-10 y resultados numéricos mediante dinámica de fluidos computacional(Universidad EAFIT, 2024) Ortega Tobón, Juan Jacobo; Jaramillo Fernández, Juan DiegoÍtem Implementación de metodología inSAR en el cálculo de deformaciones superficiales.

This process is not only time-consuming but also expensive due to the sheer number of combinations that architects need to do to arrive at the right network hyper-parameters that fit the current problem. In this work, we analyze the current state-of-the-art, in which several approaches have been proposed to automate such processes and explore alternatives for the automated design of Convolutional Neural Networks and Neural Architecture Search (NAS). Additionally, this work proposes a method for hyper-parameter variability generation from a variability model of such convolutional neural networks. The variability model proposed in this master thesis is used to represent, intensively, the valid combinations of parameters corresponding to each convolutional neural network. The language, called CNN variability language, borrows some concepts from Software Product Lines (SPL) and was created on the VariaMos platform to enable architects and engineers not just to create CNN architectures but also to automatically generate configurations, generate executable Jupyter Notebooks for each configuration, and generate comparison reports to speed up the NAS process.Ítem Velocidad de corrosión en estructuras metálicas enterradas para soporte de paneles solares(Universidad EAFIT, 2024) Lotero Carvajal, Carolina; Builes Brand, ManuelIdentification of geotechnical characteristics and definition of the calculation of corrosion rate in buried metallic structures following the Romanoff calculation method accompanied by the validation of the FHWA standard where resistivity and PH are the main characteristics. In the design of metallic structures supporting solar panels, the useful life of the structures ranges from 20 to 25 years, time in which the guarantee should be covered both against environmental corrosion and subway corrosion.Ítem Slam y Groundtruth usando marcadores(Universidad EAFIT, 2024) Escobar Acevedo, Julián; Castaño Cano, DavinsonThe present thesis project focuses on the comparison of a visual SLAM method based on ArUco markers, using these markers for both the generation of the ground truth and the execution of SLAM. The research is carried out in the environment of EAFIT University. A marker is placed on top of the robot and a panoramic camera covering the entire area where the robot is located is used for the ground truth method. For the SLAM method, a camera located on the robot is used. During the experiments, markers are distributed around the perimeter of the study site. The camera integrated into the robot allows the detection of the perimeter markers. Initially, a map of the area is created using the ROS working environment, which is compared with real measurements for validation. Subsequently, the location of the robot is determined using both methods mentioned. The obtained data are compared to analyze the variance, as well as the mean squared error (MSE), root mean squared error (RMSE), and mean absolute error (MAE). Finally, conclusions are drawn about the effectiveness of implementing this visual SLAM method either as ground truth or on the robot itself. This study contributes to the advancement in understanding and applying simultaneous localization and mapping techniques in robotic environments using ArUco markers.Ítem Comparison of gait on level and sloping ground with uneven surface among transtibial amputees with exomodular prostheses and control subjects(Universidad EAFIT, 2024) Franco Ochoa, Mariana; Rendón Vélez, ElizabethÍtem Estrategias de crecimiento para el fortalecimiento de un negocio de comercialización de vestuario(Universidad EAFIT, 2024) Hoyos Sánchez, Juan Fernando; Franco Eastman, Harold Augusto; Franco Eastman, Harold AugustoSince the middle of the last century, the textile and clothing industry in Colombia has been one of the largest sources of employment and contribution to the industrial and economic development of the country. It was during that boom time when the micro-business Creaciones Azucena was created, dedicated to the manufacturing and marketing of clothing for 36 years. However, the different phenomena of globalization such as international trade with the opening of markets, industrial renewal, overproduction, the entry of new Asian players, smuggling, the pandemic, inflation, among others, put this sector in check. in Colombia, leading it to a deep crisis and forcing the company to reduce its operation in 2018 to only market clothing. However, despite being hit so hard, this industry is still very relevant to the economy, as it serves a basic massive need such as clothing and contributed 9.4% of the GDP in Colombia in 2022. Given the above, the purpose of this study is to discover and prioritize new strategies, business models and digital technologies that allow Creaciones Azucena to take advantage of market opportunities, strengthen its operation, growth and survival in a globalized world.Ítem Hoja de ruta para la implementación del proceso de planeación de ventas y operaciones S&OP en una empresa manufacturera(Universidad EAFIT, 2024) Ramírez Zuluaga, Juan Sebastián; Castro Zuluaga, Carlos Alberto
