Using integration patterns is common in these systems to facilitate communication among computers in an asynchronous way. Event Message and Command Message, are among the most commonly used integration patterns. The performance of both patterns is analyzed in this study, considering the efficiency and the time taken to carry out a message transmission process, which may vary depending on the number and size of the messages. To carry out the analysis, the previously mentioned integration patterns were implemented in two different systems. Additionally, a comparison is performed for each pattern considering the following parameters: message size, messaging broker configurations, time between sending and receiving a message, and the name of the test type. In this way, the configurations and behavior of the integration patterns involved in the message exchange flow can be understood in a better way, as well as detect and prevent performance-related problems.Ítem Función de fragilidad para pórticos de concreto reforzado de baja altura con mampostería integrada en Colombia(Universidad EAFIT, 2023) Jaramillo Rivera, Andrea Milena; Jaramillo Fernández, Juan Diego; Lafontaine Roth, Mario AndresIn addressing uncertainty within seismic risk evaluation in Colombia, this research unveils a fragility curve derived from the nonlinear static analysis of a structure representing the prevalent low-rise residential buildings with concrete frames in the country. The exposure database from an insurance company with a substantial presence nationwide allows it to determine the structural system, the range of floors, and construction periods of interest for assessment. This database facilitated the identification of the type of buildings concentrated in highly populated cities, Bogotá, Cali, and Medellín. The study incorporated acceleration records from seismic threat assessments conducted in relevant investigations. Key characteristics were identified through interviews with various engineering firms in Colombia to select and model the typical building.Ítem A framework for Rapid Product Development based on digital techniques : an industrial case study of ceramic-based product(Universidad EAFIT, 2023) Trujillo Ángel, Luis Alfonso; Rodríguez Arroyave, Carlos ArturoÍtem Modelo de evaluación técnica, económica, medioambiental y social en proyectos de generación de energía eléctrica a partir de fuentes renovables(Universidad EAFIT, 2024) Correa Herrera, Harvy; Mejía-Gutiérrez, RicardoThis paper presents research that arises in the context of the energy transition and drive towards sustainable development in Colombia. In 2017, Colciencias launched call 778, giving rise to the Energy Alliance 2030 (E2030), led by the National University of Colombia. This alliance seeks to transform the Colombian energy sector by 2030 through Research, Development, and Innovation (R+D+i) programs. Project P3, part of E2030, focuses on Electric Mobility as a sustainable and multimodal alternative, addressing motorcycle hybridization, electric boat development, and the construction of a solar charging station and multimodal planning models. Implementation focuses on intermediate cities such as Magangué and Sincelejo. This master's project arises in response to identified barriers in the implementation of energy projects, especially in the social sphere. Literature review reveals obstacles such as lack of planning, social issues, and deficiencies in technological adoption. The work focuses on developing a comprehensive model to evaluate renewable energy generation projects from technical, economic, social, and environmental perspectives. The proposed methodology includes analysis of existing methodologies, integration of best practices, and application of a multidimensional model to the photovoltaic charging station of Project P3. It is expected that this approach will provide a comprehensive view of the viability of similar projects, reducing the risk of non-adoption or interruption.Ítem Efectos durante generación de hidrógeno en diferentes acabados geométricos de una superficie galvanizada con níquel(Universidad EAFIT, 2023) Lasprilla Holguín, David Ricardo; Ossa Henao, Edgar AlexánderIn the search for renewable energy sources, hydrogen production is an ideal alternative either because of its clean combustion without producing carbon dioxide or its long-term storage 5 capacity. Therefore, one of the methods used is water electrolysis, which is ideal for large-scale hydrogen production because it does not produce any carbon-based fuel by-product pollutants. The production of green hydrogen from water electrolysis using renewable sources such as solar or wind would facilitate long-term clean energy storage.Ítem El poder de la forma y el color : percepción de naturalidad en los snacks de chocolate(Universidad EAFIT, 2023) Abreu Domínguez, Manuela; Rendón Vélez, Elizabeth; Rendón Vélez, ElizabethÍtem Efecto del tratamiento térmico sobre la densidad y la respuesta electromecánica de una porcelana para aisladores de media tensión(Universidad EAFIT, 2023) Echeverry Otálvaro, Deysi Yuliet; Ossa Henao, Edgar AlexanderÍtem Determinación de factores de seguridad relativos al deslizamiento utilizando la metodología de taludes naturales (MTN) en la zona sub-urbana y urbana del municipio del Carmen de Atrato Chocó(Universidad EAFIT, 2023) Waldo Quinto, Francys Yadilson; Prieto Salazar, Jorge AlonsoThis work presents the zoning of an area of the municipality of Carmen de Atrato through safety factors related to landslide considering the time categories: long, medium and short term, facilitating the analysis and zoning of risk and threat, using the slope methodology. natural resources (MSN), which requires only geology and topography as main inputs. The MSN provides a series of geomechanical and stability parameters for the determination of zones through the safety factor relative to landslide, which we herein call the landslide susceptibility index, in order to offer a practical tool in the generation of preliminary information in relation to the geomechanical parameters of the study area for engineering projects related to the field of geotechnics. The present work covers the following aspects for the determination of the safety factors related to the Fsr slide: a) Measurements of the slope families, b) Construction of the triangular pattern at the population level, c) Calculation of the basic friction angle, d ) Calculation of the envelopes for the calculation of geomechanical parameters of the delimited area, e) Calculation of safety factors related to the Fsr landslide, f) Risk zoning through the construction of isovalue maps. Finally, it is obtained that the basic friction angle obtained corresponds to that expected for this type of materials, for the relative safety factors the isovalue maps are presented, however, a better estimate of the possible occurrence of future events could be to implement a model considering precipitation up to 30 years and earthquakes for different return periods. It is important to remember that relative safety factors reflect past history, but do not take into account future triggering events. The inclusion of these triggers allows for a better estimate of the future probability of landslide failure. However, the calculation of the stability parameters presented in this work corresponds to a preliminary approach to the landslide susceptibility in the analyzed area, as well as the resistance parameters of geomaterials which are useful in civil engineering projects.Ítem Aisladores de triple péndulo de fricción(Universidad EAFIT, 2023) Quintero Manzano, Andrea Camila; Jaramillo Fernández, Juan DiegoÍtem Emulsiones asfálticas con adición de Nanosílice(Universidad EAFIT, 2023) Calonge Vargas, Edgar Arturo; Vidal Valencia, JuliánThe objective of this research is to analyze the reaction of asphalt emulsions to the incorporation of nanocomposites to improve their properties and characteristics. For this purpose, tests were carried out with conventional asphalt emulsions CRL-1 and CRR-1 in which 5% and 10% of liquid nanosilica were added, by virtue of the weight of each sample, which was subjected for one hour at an agitation speed of 250 RPM at room temperature of 23 °C. Thus, it could be appreciated in the results obtained, that nanosilica changes its properties, so that such component becomes a fundamental alternative to generate materials with much more sustainable specific properties.Ítem Propuesta de adaptación del sistema de bombeo de la estación Planta de Potabilización Caldas – Tanque Paraíso para generación de energía(Universidad EAFIT, 2023) Saldarriaga Quintero, David; Botero Herrera, Francisco JavierThis paper presents a proposal for the adaptation of an existing pumping system in the drinking water network of the public service company of Medellín, Colombia, for power generation. The Caldas – La Estrella Interconnection project transports drinking water from the Ayurá drinking water treatment plant to the south of the Aburra Valley. In particular, a potential for energy use was detected in the Caldas drinking water treatment plant. It is proposed to adapt an existing pumping system so that it can also work as a turbine (PAT). For this, all technical information is gathered and classified. A statistical technical diagnosis of the equipment working as a pump is carried out based on the analysis of historical samples acquired during operation. Thus, the current state is determined and the actions are established to calculate the behavior of the pumps as a turbine. An approximate generation capacity of 50KW of electrical energy was calculated as PAT, which at the current energy cost in Colombia represents USD 44,000 per year. The energy can be used for self-consumption or delivered to the distribution network for a fairly low investment cost in equipment (approximately USD 74,000). In this way, the system can work alternately as a pump or turbine according to the needs and requirements of the aqueduct operation without jeopardizing the provision of the service.Ítem Proposal of remodulation in the facilities of the main warehouse of the company Magic Inc to increase its profits(Universidad EAFIT, 2023) Álvarez Castaño, Johnnie; Ramírez Echeverri, Sergio AugustoÍtem Modelo termodinámico de equilibrio para gasificación de biomasa, incluyendo el sólido carbonoso y la ceniza(Universidad EAFIT, 2023) Velásquez Giraldo, Gloria Janneth; Giraldo Estrada, Catalina; Quintana Marín, Germán CamiloÍtem Efectos de la sincronización de señales en la determinación del desempeño ambiental de vehículos mediante pruebas en carretera(Universidad EAFIT, 2023) Restrepo Mejía, Juan Carlos; Giraldo Galindo, Michael Daniel; Huertas Cardozo, José IgnacioÍtem NFR-Based Framework para el análisis de la Sostenibilidad en Sistemas Ciberfísicos (CPS)(Universidad EAFIT, 2023) Arce Vargas, César Augusto; Suescún Monsalve, ElizabethÍtem Implementación de herramientas de mejoramiento de procesos en el departamento de facturación de una empresa de carga internacional (3pl)(Universidad EAFIT, 2023) Sánchez Arias, Adalberto; Ramírez Echeverri, Sergio AugustoÍtem Desempeño sísmico de un pórtico de concreto armado equipado con disipadores por fricción, ubicado en zona de amenaza sísmica alta en Colombia(Universidad EAFIT, 2023) Hernández Montes, Clímaco Andrés; Jaramillo Fernández, Juan DiegoFriction dampers are seismic response control devices that dissipate the energy imparted by an earthquake to a structure through the friction between two solid surfaces. In this study, the seismic performance of a reinforced concrete frame located in a high seismic hazard zone in Colombia is evaluated under two specific scenarios: In the first scenario, the frame is analyzed without dampers, and in the second scenario, the frame is analyzed with friction dampers. The structure was previously designed according to the Colombian seismic-resistant construction code (NSR-10). The evaluation is performed in terms of the maximum demands of ductility at the global level for the frame and the local level for beams and columns. To accomplish this, nonlinear time-history analyses of a set of 14 seismic records representative of the seismic hazard were conducted, and it was found that the seismic performance of the frame significantly improved when the dampers were incorporated into the proposed structure for the study, absorbing at least 50% of the seismic energy. As a result, the global ductility demand of the structure decreased by an average of 52.8%, and the ductility demands in the beams and columns decreased by 54.1% and 25.1%, respectively.
