Development of a thermoelectric test for electrical contactors
PABLO OROZCO CORRAL FRANCISCO JAVIER IBARRA VILLEGAS NOE VILLA VILLASEÑOR (2023)
In the economic model in which we develop, there is a dependence on the means of transport that every day is increasing and due to the importance of electrification in the issue of efficient and clean transportation, has caused the need for companies supplying components for automotive manufacturers to evolve and develop new technologies to stay ahead of the needs of their customers being in full evolution towards electrified transport. This evolution extends not only to manufacturing but to the test methods that currently exist, since automotive standards require suppliers to test in laboratory, the components they sell to their customers to ensure their correct operation.

Maize seed aid and seed systems development: Opportunities for synergies in Uganda
Jason Donovan Rachel Voss Pieter Rutsaert (2024)
In the name of food security, governments and NGOs purchase large volumes of maize seed in non-relief situations to provide at reduced or no cost to producers. At the same time, efforts to build formal maize seed systems have been frustrated by slow turnover rates – the dominance of older seed products in the market over newer, higher performing ones. Under certain conditions, governments and NGO seed aid purchases can support formal seed systems development in three ways: i) support increased producer awareness of new products, ii) support local private seed industry development, and iii) advance equity goals by targeting aid to the most vulnerable of producers who lack the capacity to purchase seeds. This study explores the objectives and activities of seed aid programmes in Uganda and their interactions with the maize seed sector. We draw insights from interviews with representatives of seed companies, NGOs and government agencies, as well as focus group discussions with producers. The findings indicated that seed aid programme objectives are largely disconnected from broader seed systems development goals. There is little evidence of public-private collaboration in design of these programmes. Better designed programs have the potential to align with varietal turnover objectives, commercial sector development and targeting of underserved markets could promote equity and ‘crowd in’ demand.

Modular ontology to support manufacturing SMEs toward industry 4.0
ZAIDA ANTONIETA MORA ALVAREZ OSCAR HERNANDEZ URIBE RAMON ALBERTO LUQUE MORALES LEONOR ADRIANA CARDENAS ROBLEDO (2023)
Industry 4.0 (I4.0) implementation is a hot topic among manufacturing organizations to reach smart factory status and integrate a fully connected ecosystem. Achieving such a transition presents notable challenges for Small and Medium Enterprises (SMEs) since they often face resource and skilled personnel limitations. This study developed a domain ontology to represent various stages of maturity toward I4.0 implementation. Ontology provides a tool for SMEs to self-assess in situations of machines, processes, and factories for the dimensions of control, integration, and intelligence. This study focused on the identification of classes and relationships according to I4.0 implementation situations in the context of a manufacturing setting, the reuse of ontologies related to the domain of observations to model situations, and the creation and validation of the ontology through the information obtained from the questionnaires applied to SMEs. Finally, the ontology delivers a tool to understand SMEs' current state concerning I4.0 implementation and plan based on informed decisions about the maturity state and the technology required to advance to the next stage in their manufacturing processes.
This study was partially supported by the grants CONAHCYT-CIATEQ CVU 899567 and 162867 and CONAHCYT SNI.
We express our gratitude to Teresa Novales Hernandez for the library support.

Vivimos la industria 4.0, misma que no es nueva, ya que sus orígenes se remontan a finales de la década de los 2000, en Alemania. Un pilar de la industria 4.0 es el análisis de datos, conocido como Big Data. El conocer los datos de un proceso, de un estudio, ayuda en gran medida a predecir el comportamiento que tendrá el proceso o la máquina a estudiar en un periodo a corto o mediano plazo. En el presente proyecto se analizan los datos arrojados por un motor eléctrico de corriente alterna, del tipo inducción, jaula de ardilla. El motor está diseñado para trabajar de manera continua, sin embargo, el uso que se le da, es meramente educativo; es decir, no sobre pasa las 15 horas por semana de uso. Mediante la toma de datos de las tres fases de corriente RMS o corriente de valor eficaz que posee el motor eléctrico que se realizará con el microcontrolador Arduino UNO, se analizarán los mismos mediante el software de cómputo numérico MATLAB, ordenando los datos, descartando valores que no aporten información relevante para lograr la predicción de datos. Por último, se llevará a conocer este proyecto a la carrera mecatrónica, área sistemas de manufactura flexible y área automatización, con el fin de que puedan observar de una mejor manera la aplicación y funcionamiento de uno de los pilares de la actual industria 4.0.
We live in industry 4.0, which is not new, since its origins date back to the late 2000s, in Germany. One pillar of industry 4.0 is data analysis, known as Big Data. Knowing the data of a process, of a study, helps greatly to predict the behavior that the process or machine will have to study in a short- or medium-term period. This project analyzes the data released by an electric motor of alternating current, of the type induction, squirrel cage. The engine is designed to work continuously, however, the use given to it is merely educational, that is; only not over spends 15 hours per week of use. By taking data from the three phases of RMS current or effective value current of the electric motor that will be made with the Arduino UNO micro controller, they will be analyzed using MATLAB numerical computing software, ordering the data, discarding values that do not provide relevant information to achieve data prediction. Finally, this project will be presented to the mechatronics career, flexible manufacturing systems area and automation area, so that they can observe in a better way the application and operation of one of the pillars of the current industry 4.0.

Este artículo presenta la implementación de un sistema de visión para la detección de fallas en la identificación de etiquetas en una línea de producción de motores eléctricos de confort para vehículos. Anteriormente, la línea de producción dependía completamente de la inspección visual realizada por un operador. La solución propuesta considera tanto los aspectos técnicos del sistema de visión como otros factores clave para asegurar la calidad del proceso, como: las políticas de aseguramiento de calidad de las normas automotrices vigentes en México (IATF 6949:2016 e ISO9000), la mejora continua, la estadística, la ergonomía y la estandarización de procesos. Los resultados demuestran el éxito de la implementación. El sistema demostró ser efectivo al identificar las fallas de manera precisa; se logró una reducción significativa en el número prioritario de riesgo en el análisis y modo de efectos de falla; y se logró una reducción en la estadística de fallas internas y con el cliente, de 2021 a 2022.

En este artículo se analizarán desde una perspectiva jungiana y holística una selección de momentos dancísticos y escultóricos en tres obras dramáticas del corpus teatral mitológico del autor cubano Eugenio Hernández Espinosa (María Antonia, 1967; Odebí, el cazador, 1980, y El Elegido, 1995), protagonizadas en los tres casos por diferentes orishas, nombre con el que se conocen popularmente en Cuba —concretamente en la tradición cultural y espiritual yoruba de la isla— a las manifestaciones antropomórficas, físicas, vivenciales y sobrenaturales de la divinidad. El paradigma de análisis aplicado es principalmente el del pensamiento integral de Ken Wilber, por el cual cuerpo-mente-psique-divinidad se conciben como un todo interconectado, integrado y resonador dentro del proceso de individualización de la persona, siendo el cuerpo el vehículo, el espejo, la palanca y la puerta de acceso, es decir, siendo el cuerpo el que refleja, activa y abre el resto de las dimensiones.
In this article, a selection of dance and sculptural moments in three dramatic works from the mythological theatrical corpus of Cuban author Eugenio Hernández Espinosa will be analyzed from a Jungian and holistic perspective (María Antonia, 1967; Odebí, the Hunter, 1980, and The Chosen, 1995). All three plays star a selection of Orishas, the name by which the anthropomorphic, physical, experiential and supernatural manifestations of divinity are popularly known in Cuba — specifically in the island’s Yoruba cultural and spiritual tradition. The analytical paradigm to be applied is mainly Ken Wilber’s integral thought, by which body-mind-psyche-divinity are conceived as an interconnected, integrated and resonating whole within the person’s individualization process, the body being the vehicle, the mirror, the lever and the access door, that is, the body being the one which reflects, activates and opens the rest of the dimensions.
