APPLICATION OF PROBLEM-BASED LEARNING FOR THE DEVELOPMENT OF A CLASSROOM PROJECT IN THE FUNDAMENTALS OF CONTROL AND AUTOMATION COURSE

This article presents the application of the problem-based learning methodology applied in a classroom project, the development of this learning methodology is framed in the social constructivist pedagogical model focusing the generation of new knowledge in the student and placing the teacher as a facilitator. This methodology starts with the selection of the work group, this was achieved by identifying the learning styles of each student through the Honey - Alonso learning styles identification test, which showed that 40% of the students have a pragmatic learning style, 30% have an active learning style, 20% have a pragmatic learning style, and 20% have an active learning style, and the rest have a pragmatic learning style, This is important when it comes to teamwork, since each member contributes from his or her capacity to acquire knowledge and there is a relationship between the learning style and the leadership and moderation roles required for such work. After organizing the work group, the problem-based methodology was developed, with the correct identification of the problem, going through a brainstorming process and finally proposing a solution. The solution proposed was the design of a solar photovoltaic plant, and its design is presented as an evaluation method for the development process of the problem-based learning methodology

Sustainable Construction Of Rural Housing In Guadua: A Step-By-Step Learning For Rural Communities

Population growth has generated the search for fast, economical and environmental housing alternatives that guarantee the wellbeing of the population.  In recent years, the use of plant-based materials in construction has increased, from ancestral practices to the technical aspects based on the Colombian Seismic Resistant Construction Regulation NSR-10. This article explains the sustainable construction systems of guadua housing for rural communities in Colombia, seeking to take advantage of the available resources, the natural properties of guadua and the low costs of the material, with the generation of a pedagogical manual for the use of this resource and the learning of rural communities so that they can make their own construction of guadua housing. The guadua construction pedagogical manual contains specifications, preparation, tools, type of cuts, type of joints, material protection, construction systems and process recommendations. Guadua construction for rural communities in Colombia is a viable alternative from an economic, environmental and social point of view, as it is a low-cost resource available in the country, and generates the possibility of solving housing problems for people affected by natural disasters, conflicts, among others

Classification and correlation of surface roughness in metallic parts using texture descriptors

En este artículo presentamos un método para clasificar la rugosidad superficial en piezas metálicas, después de mecanizar procesos, utilizando un sistema de visión artificial. Se utilizan dos métodos de análisis de texturas: matriz de co-ocurrencia (GLCM) y la energía de la textura obtenida por el método de las leyes. Estos descriptores se clasifican con análisis de discriminantes lineales y cuadráticos (LDA y QDA) y redes neuronales artificiales (ANN). Los mejores resultados se han logrado utilizando la máscara de leyes R5R5 (94,03%) y el descriptor de correlación combinado extraído del GLCM (94,23%), ambos clasificados utilizando redes neuronales. Estos resultados muestran el éxito del método y la posibilidad de correlacionar estos descriptores con la rugosidad media (RA)

Segmentación de cabezas de espermatozoides de verraco mediante combinación de umbralización y transformada Watershed

Se ha desarrollado un nuevo m´etodo que per- mite segmentar im´agenes de cabezas de esper- matozoides vivos y muertos. Las im´agenes se han adquirido utilizando una c´amara AVT Os- car F-810C y un microscopio de epifluorescen- cia Nikon E-600. La segmentaci´on se realiz´o sobre im´agenes obtenidas en escala de grises y se uti- lizaron las im´agenes de fluorescencia para etique- tar cada cabeza para evaluar el m´etodo. ´ Este con- siste en segmentar la mayor parte de las im´agenes mediante un preprocesamiento y umbralizaci´on basada en Otsu y las im´agenes que resulten mal segmentadas procesarlas mediante una transfor- mada Watershed. Se eval´ua autom´aticamente si la segmentaci´on es correcta tras realizar la seg- mentaci´on. De esta manera se consigue segmentar correctamente un 97.39% de los espermatozoides vivos y un 82.99% de los espermatozoides muer- tos

Evaluación de diferentes tipos de iluminación para la clasificación de la rugosidad de piezas metálicas mediante análisis de imagen

En este trabajo se clasifica la rugosidad de piezas metálicas en procesos de torneado mediante análisis de imagen, y se evalúa la incidencia de la iluminación de acuerdo al ángulo utilizado. Para describir la rugosidad de la superficie, a partir de la imagen obtenida, se ha utilizado un vector compuesto por cuatro descriptores de primer orden (DPO): media, desviación estándar, coeficiente de asimetría y kurtosis. Como clasificador se utilizó Knn. Se obtuvieron 284 imágenes sobre las que se calcularon los anteriores descriptores y la clasificación obtenida se comparó con la rugosidad media de las piezas calculadas por un método tradicional. El porcentaje de error obtenido para cada tipo de iluminación fue coaxial 0.70%, angular 9,68% y rasante 1.03%. Los resultados de la clasificación mediante diferentes tipos de iluminación demuestran la importancia de dicho proceso el cual puede incidir en errores a la hora de obtener la rugosidad y a la vez la efectividad de los descriptores de textura en la obtención del respectivo valor

Clasificación de residuos de construcción y demolición mediante un kernel modificado de Laws
