Construction and Simulation of a Planar Transformer Prototype

This paper illustrates the design and building of a planar transformer prototype with a 1:1 transformation ratio for high-frequency applications in power electronics. By using reference literature and considering the ferrite core dimensions, the windings were conceived and exported to Gerber format using PCB design software. The transformer prototype was then assembled and tested under laboratory conditions for frequencies from 800 Hz to 5 MHz, which showed a sinusoidal wave at the transformer output from 1.3 kHz onwards and a better performance starting at 10 kHz, where the loses were significantly reduced and the transformation ratio was closer to the originally designed. As a final step, a finite element method (FEM) analysis was carried out to understand the electromagnetic flux behavior using a 3D Multiphysics simulation software. The 3d building process and details are explained step by step and the resulting magnetic flux density is graphically shown for the core and the windings.Universidad Tecnológica de Bolíva

Learning Factory: The Path to Industry 4.0

Abstract Nowadays, there are plenty of studies that seek to determine which are the skills that should be met by an engineer. Communication and teamwork are some of the most recurrent ones associated with a knowledge of the engineering sciences. However, their application is not straight forward, due to the lack of educational approaches that contributes to develop experience-based knowledge. Learning Factories (LF) have shown to be effective for developing theoretical and practical knowledge in a real production environment. This article describes the transformation process of a training-addressed manufacturing workshop, in order to structure a Learning Factory for the production engineering program at EAFIT University. The proposed transformations were based on the definition of three pillars (didactic, integrative and engineering) for the development of an LF. We argue that a proper transformation process may contribute to ease the path towards new manufacturing trends such as industry 4.0 into an academic context that strengths the engineering training process

Evidence for increasing global wheat yield potential

Wheat is the most widely grown food crop, with 761 Mt produced globally in 2020. To meet the expected grain demand by mid-century, wheat breeding strategies must continue to improve upon yield-advancing physiological traits, regardless of climate change impacts. Here, the best performing doubled haploid (DH) crosses with an increased canopy photosynthesis from wheat field experiments in the literature were extrapolated to the global scale with a multi-model ensemble of process-based wheat crop models to estimate global wheat production. The DH field experiments were also used to determine a quantitative relationship between wheat production and solar radiation to estimate genetic yield potential. The multi-model ensemble projected a global annual wheat production of 1050 ± 145 Mt due to the improved canopy photosynthesis, a 37% increase, without expanding cropping area. Achieving this genetic yield potential would meet the lower estimate of the projected grain demand in 2050, albeit with considerable challenges.Fil: Guarin, Jose Rafael.

Evaluación de las competencias de los egresados de odontología de la Universidad Cooperativa de Colombia sede Medellín desde la perspectiva de los empleadores.

Las posibilidades de empleo hoy en día se basan en la capacitación profesional y en las posibilidades de adaptación a un entorno laboral cambiante, contexto especialmente importante en Colombia que tiene una de las tazas de desempleo más altas del mundo. En el campo de la odontología se presenta una sobreoferta laboral con respecto a la demanda reflejándose en un desempleo creciente y que tienden a aumentar en algunos años. El presente estudio evalúo las competencias y habilidades laborales de los egresados y los requerimientos actuales para un mejor ingreso al mundo laboral. Para esto se realizó un estudio descriptivo con empleadores de clínicas odontológicas públicas y privadas que tuvieran egresados de la facultad. Los empleadores consideran que los odontólogos egresados de la Facultad reúnen las competencias requeridas para el trabajo en sus clínicas. En relación a los aspectos de mayor fortaleza referidos se tienen la aplicación de estándares éticos y legales en la atención dental, habilidades en procedimientos restauradores, habilidades para el manejo de tratamiento en cirugía oral simple y compleja, el diagnostico, identificación y manejo de enfermedades pulpares y peri radiculares. Es necesario profundizar en aspectos administrativos, trabajo comunitario y estética dental. Dentro de las problemáticas actuales de la profesión se encuentra la sobreoferta odontológica y la desvalorización del trabajo.Employment opportunities today are based on professional capacity and the possibility of adapting to a changing work environment, which is especially important in Colombia given it has one of the highest unemployment rates in the world. In the field of Dentistry, the labor oversupply relative to demand reflects in said unemployment rates that tends to increase every couple of years. The study evaluated professional competence and abilities of incoming workforce as well as actual requirements for a better entry to such. For this, a descriptive study was carried out with employers of public and private odontology clinics that had new employees from the faculty. The employers consider that the incoming odontologists that graduated from said faculty meet the requirements to work at their clinics. It is necessary to dive deeper into the administrative aspects, community work, and dental aesthetics. Among the current problems of the dentistry profession, we find the dental oversupply and devaluation of dentistry [email protected]@[email protected]@[email protected]@campusucc.edu.c
