The flipped classroom is a method of educational innovation that has been evolving since its beginning by incorporating other models of innovation such as adaptive learning. This paper presents a state-of-the-art study on the application of flipped classroom models together with adaptive techniques to personalize learning. The analysis has been performed from several dimensions: platforms, technologies and training models. Based on this analysis and the authors’ experience in developing Adaptive Flipped Classroom model, a multimodal model has been created that is applicable to any dimension and situation. The model is mainly based on making the “lesson at home” activity of the adaptive flipped classroom method. This activity is based on analyses performed at different points in time: pre, during and post. In other terms, it is a matter of applying adaptive techniques after analyzing the obtained information about the students’ interaction with the technology and with his or her learning. Three partial models and one generic are defined depending on where adaptability is done. The resulting model allows to do learning adaptations throughout the training process in a flexible way and independently of the chosen technological solution.

In the teaching field, the existence of automated procedures that allow self-assessment or self-correction of exercises or exams is a great help. Most web learning applications generate tests with single, multiple, or text answers, or the use of closed-solution problems where only the student’s final answer is validated. The complexity increases when we try to score a text, but the most difficult evaluation is in the field of Graphic Engineering, inside CAD/CAM environments. The student assessment usually uses the revision of a digital file with a solution. While it is true that some software may offer tools to compare files, these are focused on the search for differences in their own versioning. When the 3D industrial model is created by students, the tools, planes or geometric sketches are very varied, and an automated assessment is not a simple task. This paper attempts to offer a possible way for the automated correction of the 3D modelling in industrial parts based on some parameters proposed. A programme, called CPIT (Corrector of Three-Dimensional Industrial Parts), has been designed to evaluate the similarity between parts within the CATIA® V5R19 environment using Visual Basic for Applications (VBA). This first version has been tested successfully with several exercises and it is necessary to improve some aspects of it, such as its performance in complex pieces or Boolean operation.
Personalized Flipped Classroom
(Springer Nature, 2023) Sein-Echaluce, María Luisa; Fidalgo Blanco, Ángel; Martín-Núñez, José Luis; Verdú Vázquez, Amparo; García Ruesgas, Laura; Universidad de Sevilla.

In this research work, a Personalized Flipped Classroom model has been developed and applied, consisting of carrying out a personalized lesson at home. The model allows students to learn the lessons and carry out micro-activities based on their level of knowledge and preparation. The model is designed by establishing groups of students according to their level of knowledge and, in this way, personalized activities are designed for each group, which are carried out cooperatively and collectively. The model was applied in an engineering subject and to carry out the study of the experience, a control group with 38 students and an experimental group with 35 students were established. The results of the experience show an improvement in the performance of the students as a result of the personalized activities designed. In addition, the designed model has encouraged students to self-organize themselves by levels of knowledge in other complementary activities to the Flipped Classroom (FC) method, such as tutorials
Synthetic generation of Monge Surfaces through folding and its applications to the design of architectural envelopes
(Editorial Sociedad Iberoamericana de Gráfica Digital, 2024-11-13) Martín Pastor, Andrés; González Quintial, Francisco; Universidad de Sevilla. Departamento de Ingeniería Gráfica; Herrera, Pablo C.; Gómez, Paula; Estévez. Alberto T.; Torreblanca Díaz, David A.; Universidad de Sevilla. HUM976: Expregráfica. Lugar, Arquitectura y Dibujo
This work is based on the reinterpretation of the Monge Surface through the logic of growth by folding, in a context of hybridization between digital processes and digital fabrication. We propose the construction of a discrete Monge Surface from the movement of a set of flat surfaces superimposed and linked to each other. The generation law that we propose presents certain conditions that guarantee that the generated meshes have specific geometric properties, which will be relevant for the design and materialization of architectural envelopes. Finally, we present different case studies and their application in architecture.
Discrete Variable Conditional 3D Models in Computer Extended Descriptive Geometry (CeDG): Preliminary Study on Cylindrical Polygonal Sheet-Metal Elbow
(Springer Nature, 2024-02-02) Prado-Velasco, Manuel; García Ruesgas, Laura; Universidad de Sevilla. Departamento de Ingeniería Gráfica
Computer extended Descriptive Geometry (CeDG) technique has demonstrated its ability to build parametric computational models of 3D systems supported by Descriptive Geometry procedures in previous studies. When a parameter causes a non-continuous and qualitative change in the 3D model, it requires an additional logic. The treatment of visibility is a well-studied example of qualitative changes that are associated with continuous parameters. We are interested in qualitative changes associated with discrete parameters (discrete variable conditional 3D models). This work deals with the preliminary study of a methodology for the construction of such 3D models. A cylindrical polygonal sheet-metal elbow model of n ferrules (neutral surface) with the ability to cater for the change of variable n (n > 2, discrete) is used in this work as a target system to study the limits and accuracy of CeDG based on GeoGebra in the construction of discrete variable conditional models. We successfully achieved a conditional CeDG model (3D), including the flat pattern, for any number of ferrules. This model overpasses the scope of the polygonal elbow model from LogiTRACE v14, which is restricted to n<=12. In addition, flat patterns in CeDG are exact in opposition to that of LogiTRACE, which are prismatic approximation with a given number of generatrices.
Intersection Between Surfaces Using Computer Extended Descriptive Geometry (CeDG): Application to the Focal Illumination of a Sphere
(Springer Nature, 2023-02-14) Prado-Velasco, Manuel; García Ruesgas, Laura; Universidad de Sevilla. Departamento de Ingeniería Gráfica
Computer Extended Descriptive Geometry (CeDG) is a new approach to computer modelling of 3D geometric systems that tries to overcome several limitations of current CAD systems. A preliminary version of CeDG for GeoGebra has demonstrated advantages in sheet metal and mechanisms field. This paper develops the theoretical basis of the Locus-based Surfaces’ Intersection Method (LSIM) of CeDG and compares it against the standard Descriptive Geometry technique, through the calculation of the illumination of a sphere by a focal light beam. Results showed that, in opposition to standard Descriptive Geometry technique, the LSIM CeDG model combines less complexity (geometric procedure requires only one iteration) with the capability to be extended to other parameters’ values and projections, keeping the compliance with geometrical requirements. Accuracy metrics have demonstrated that LSIM can generate the exact (true) surface intersection curve through its projections, thanks to the geometric integrity of the underlying dynamic geometry software (GeoGebra).

Este trabajo describe el proceso de digitalización del manto de Salida de Nuestra Señora del Socorro, titular de la hermandad del Amor. Se trata de una pieza emblemática del arte textil sacro sevillano. El objeto de estudio tiene unas dimensiones de 4,80 x 4,60 metros, confeccionado en terciopelo granate sobre el que se aplica un denso bordado en oro. Realizado en 1957, el manto ha sido sometido a un proceso de restauración durante los dos últimos años. Al término de este proceso, se realiza una virtualización transfiriendo técnicas de levantamiento arquitectónico a la documentación de su estado restaurado. En el proceso de trabajo se han mezclado técnicas de planificación de vuelo provenientes de la fotogrametría aérea, con equipos topográficos y fotográficos propios de la fotogrametría terrestre. Los resultados obtenidos, en alta resolución, consisten en un banco de imágenes, modelos digitales, ortofotos y secciones, así como vídeos destinados a favorecer la divulgación del bien. Estos productos permiten un profundo análisis de la geometría y de las técnicas y materiales empleados sobre el manto, elementos de gran utilidad para la conservación preventiva. El trabajo, pionero en objetos textiles de estas características, ha precisado adaptar las técnicas y los equipos al entorno de trabajo de un taller de bordado, así como a las sutilezas que imponen los materiales textiles, brillantes y sagrados sobre los que se ha actuado.
Large-scale photogrammetry: the case of the Roman baths of Alange, Badajoz (Spain)
(Universidad Politécnica de Valencia, 2024) Conejero Gascón, David; Millán Millán, Pablo Manuel; Infante Perea, Margarita Mª; Cantillana Merchante, Concepción; Universidad de Sevilla.

Photogrammetry applied to heritage documentation has undergone significant development in recent years. The research objective we present is to synthesise the result of the work carried out by employing and studying the application of large-scale photogrammetric techniques in an integrated manner coherently and exhaustively. This research has been applied in the Roman Baths of Alange case, which was declared a World Heritage Site (UNESCO, 1993). This significant ensemble lacks detailed planimetric documentation and archaeological interventions. This research has established a comprehensive overview of the difficulties affecting the characteristics of the photogrammetric technique and its development in architecturally complex, narrow, enormous, and data collectionchallenging places. This has been reflected in a point cloud of the surveyed site. Thus, the aim is to understand the scope of the technique and analyse each of its characteristics.

(Faculty of Civil Engineering, Czech Technical University in Prague, 2011-12-21) Remondino, Fabio; Rizzi, Alessandro; Jiménez Fernández-Palacios, Belén; Agugiaro, Giorgio; Baratti, Giorgio; De Amicis, Raffaele; Universidad de Sevilla. Departamento de Ingeniería Gráfica
Geomatics and Geoinformatics deal with spatial and geographic information, 3D surveying and modeling as well as information science infrastructures. Geomatics and Geoinformatics are thus involved in cartography, mapping, photogrammetry, remote sensing, laser scanning, Geographic Information Systems (GIS), Global Navigation Satellite Systems (GNSS), geo-visualisation, geospatial data analysis and Cultural Heritage documentation. In particular the Cultural Heritage field can largely benefit from different Information and Communication Technologies (ICT) tools to make digital heritage information more informative for documentation and conservation issues, archaeological analyses or virtual museums. This work presents the 3D surveying and modeling of different Etruscan heritage sites with their underground frescoed tombs dating back to VII-IV century B.C.. The recorded and processed 3D data are used, beside digital conservation, preservation, transmission to future generations and studies purposes, to create digital contents for virtual visits, museum exhibitions, better access and communication of the heritage information, etc.
Deformaciones locales en el primer plano urbano completo de Sevilla: hallazgos inéditos desde un nuevo enfoque
(Ediciones UPCT (Universidad Politécnica de Cartagena), 2022) Aguilar Camacho, Joaquín; Granado Castro, Gabriel; Cabrera Revuelta, Elena; Universidad de Sevilla. Departamento de Ingeniería Gráfica; Universidad de Sevilla. TEP156: Ingeniería Gráfica y Cartográfica
La comparación visual o mediante superposición constituyen metodologías de análisis, cada vez menos utilizadas en la literatura, para el estudio de la exactitud posicional de un mapa histórico. En ellas, se sustentan dos trabajos previos acerca de las deformaciones presentes en el primer plano urbano completo y conocido de la ciudad de Sevilla (1771). Este trabajo vuelve a evaluar la exactitud del conocido como plano de Olavide, en referencia a su promotor, aplicando un enfoque metodológico diferente. El carácter innovador subyace en dos aspectos: el análisis, por separado, de las cuatro hojas que componen el plano y la aplicación de una herramienta específica para la visualización local de las deformaciones presentes en un mapa histórico, como es el caso de MapAnalyst. La exactitud de la escala y la orientación del plano, también han sido comprobadas con ayuda de esta aplicación. Los resultados permiten ampliar con nuevos datos la información divulgada, hasta la fecha, sobre la exactitud del primer testimonio gráfico de la ciudad. Además, el estudio pormenorizado de las deformaciones locales presentes en el documento aporta un novedoso hallazgo, en relación al procedimiento de levantamiento seguido, que cuestiona la principal hipótesis sostenida hasta el momento.

(2015) Narváez Rodríguez, Roberto; Barrera Vera, José Antonio; Universidad de Sevilla. Departamento de Ingeniería Gráfica; Universidad de Sevilla. TEP156: Ingeniería Gráfica y Cartográfica
The Caterpillar gallery was a teaching innovation project intended to integrate geometry, parametric design and digital fabrication at the earliest stage of the undergraduate training period. This paper shows the contents, based on this project, of the workshop carried out within the 33rd eCAADe conference, Vienna 2015. The geometrical principles -stemming from certain quadrics theorems-, the parametric definition and the digital fabrication of the reduced-scale model executed in the workshop are outlined and illustrated.
Access and web-sharing of 3D digital documentation of environmental and architectural heritage
(Leibniz University Hannover, 2019) Tommasi, Cinzia; Fiorillo, Fausta; Jiménez Fernández-Palacios, Belén; Achille, Cristiana; Universidad de Sevilla. Departamento de Ingeniería Gráfica
The techniques and methods to capture and represent in a three-dimensional digital space the shape of objects belonging to Cultural Heritage have become more widespread, regarding both the economic and practical accessibility of technologies and equipment. At the same time, systems and tools have developed to integrate different 3D survey techniques that allow to achievement a complete acquisition of the tangible assets, considering the purposes of the survey, the required accuracy and the representation scale. The product of an integrated (image-based and range-base acquisition) and multi-scale (architectural and landscape scale) digital survey is a metric 3D reconstruction, potentially suitable for a broader ‘use’ and ‘user’ and not only for visualisation and documentation. According to this vision, the 3D model becomes a container of information, which include different type of data depending on the users and the aim of the work. The final result of this process can be the valorisation of the Cultural Heritage and its environment, through the access from experts and non-experts users. The aim of the article is showing the entire pipeline for 3D measurement, survey data acquisition, modelling, and representation of tangible assets and the related layers of information, as “best practice” to improve the Cultural Heritage knowledge, fruition, and sharing.
Analizando el empleo de las localizaciones de los usuarios de la Red Andaluza de Posicionamiento en la actualización cartográfica
(Colegio Oficial de Ingenieros Técnicos en Topografía, 2022) Torrecillas Lozano, Cristina; Verdú, Amparo; García Ruesgas, Laura; Marín-Buzón, Carmen
La Base Cartográfica de Andalucía 1:10.000, generada por el Instituto de Estadística y Cartografía de Andalucía, emplea actualmente tiempos para su actualización vinculados con la periodicidad de los vuelos del Plan Nacional de Ortofotografía Aérea (3-4 años). Además, su actualización suele seguir un recorrido hoja a hoja. Lo que se presenta en esta comunicación es la validación del empleo de las localizaciones de los usuarios de la Red Andaluza de Posicionamiento (RAP), un sistema de correcciones regionales, para la identificación de obras. Se han realizado dos análisis, uno centrado en el crecimiento urbano y, un segundo vinculado a la identificación de las obras asociadas a los patrones lineales. El estudio en las zonas urbanas permitió ver que la red está presente en las grandes obras de urbanización y las destinadas a servicios o equipamientos. Respecto a las obras lineales, ha conseguido detectar, superando el 85%, nuevos trazados de carreteras, ferrocarriles o líneas eléctricas. Estas cifras muestran estas conexiones a la RAP como un dato a tener en cuenta para detectar zonas donde se producen los mayores cambios realizados por el hombre, con la gran ventaja de la posibilidad de identificarlos con antelación a su materialización o construcción.

(Universidad Politécnica de Cartagena, 2022) Cabrera Revuelta, Elena; Aguilar Camacho, Joaquín; Granado Castro, Gabriel; Universidad de Sevilla. Departamento de Ingeniería Gráfica; Universidad de Sevilla. TEP156: Ingeniería Gráfica y Cartográfica
Los avances tecnológicos en materia de fotogrametría digital hacen posible obtener resultados suficientemente precisos con independencia de la cámara fotográfica utilizada. El presente trabajo se centra en la aplicación de una metodología concreta para obtener modelos tridimensionales de alta precisión mediante técnicas fotogramétricas, comparando el proceso y los resultados obtenidos al utilizar dos objetivos de cámara distintos. Para la realización de este análisis comparativo se han seleccionado piezas de yesería de gran valor patrimonial como caso de estudio. Se trata de dos frisos ubicados en el Patio de las Doncellas del Real Alcázar de Sevilla. Como resultado de este estudio se han podido obtener conclusiones acerca de la incidencia de las características del objetivo de la cámara tanto en el proceso de medición y procesado de datos, así como en la precisión del modelo tridimensional obtenido.

Ambos servicios están integrados en una aplicación desarrollada en un entorno web que proporciona una gestión integral de la toponimia: desde su consulta e introducción de datos hasta su normalización y difusión. Dichos servicios publican sincrónicamente en la red los nombres geográficos contenidos en una única base de datos que contiene el Nomenclátor Geográfico de Andalucía: unos 150 000 topónimos clasificados temáticamente en área administrativa, entidad de población, medio físico (terrestre y marítimo), hidrografía, patrimonio, infraestructura, servicio y actividad industrial, localizados con coordenadas UTM en ED50. Su creación ha tenido como objetivo satisfacer las necesidades divulgativas y técnicas de la mayoría de los usuarios que requieren, profesional, académica o particularmente, de la toponimia en sus estudios lingüísticos, territoriales, medioambientales, históricos, turísticos o de ocio.
Understanding vertical ground displacement from P-SBAS using Getis-Ord GI* statistic
(Editorial Universitat Politècnica de València, 2021) Barbero, I.; Páez, R.; Torrecillas Lozano, Cristina; Universidad de Sevilla. Departamento de Ingeniería Gráfica
The Differential Synthetic Aperture Radar Interferometric (DInSAR) algorithm has already shown its importance in volcanicmonitoring. However, it is limited by atmospheric perturbations or temporal decorrelation, implying the existence of lowcoherencerecords that must be discarded. In vast studied areas, with thousands of points unevenly distributed, theinterpretation of the results is usually complicated. This text presents an analysis of the vertical component variation onTenerife island (Canary Islands), from 2005 to 2010, using Getis-Ord Gi* spatial statistic on ENVISAT DinSAR images.The ascending and descending images have been processed using the Parallel Small BAseline Subset (P-SBAS)algorithm, within ESA Grid Processing on Demand cloud environment. From Line of Sight results of both tracks, the verticaldeformation speeds have been calculated over 72,207 points with high coherence (> 0.7). Finally, the Gi* statistic hasbeen applied, obtaining a map with statistical significance, where the high values of Gi*, both positive and negative, implythe spatial clustering of likely ground movements. This map highlights areas with variable vertical kinematics on TenerifeIsland, contributing to understanding of its geodynamics. The displacements obtained coincide with previous studies, evenshowing possible new relationships between some phenomena that should be considered. The Gi* spatial statistic is anefficient and quick tool to extract information in a regional scale kinematic study.

limited in the Spanish legislation to the study of the construction costs. Due to new legislative changes, with the appearance of the Directive 2014/24/UE about public procurement. Hereinafter public institutions must take into account in public procurements, economic indicators that include life cycle cost(LCC) of the building. The main objective, of the research, is to design a methodology that adapts the assessment of the costs of the building construction to a study that allows the calculation of the budgeting of Whole-life cycle cost (WLC) at the first stages of development of the design. The methodology will be based on the structures of LCC, such as EN-15643-4, ISO 15686-5. And in the data of project of similar type, and Andalusian Construcction cost bank. The methodology would let know a forecast of cost associated to building service life from first stages of project development and would an economic indicator of sustainability, useful for management of the public economic sources.

Capiteles sevillanos. Técnicas avanzadas para su documentación gráfica.
(2012) Molero Alonso, Borja; Cabrera Revuelta, Elena; Benavides López, José Antonio; Pino Suárez, Ruth; Barrera Vera, José Antonio; Universidad de Sevilla. Departamento de Ingeniería Gráfica
Recent developments in the field of documentation of cultural heritage using digital photogrammetry and scanning have led to a renewed interest in techniques and processes that are being used to get geometric models of heritage. So far, however, there has been little discussion about the definition of standardized processes in order to ensure homogeneity and interoperability. On the other hand, very valuable information of the buildings is contained by capitals. The aim of our research is to get a protocol in the documentation of this kind of architectural elements, through the use and comparison of new technologies in the graphic documentation. For this purpose, we have used photogrammetric techniques and optical scanners in order to obtain field data, specialized software management and modeling point clouds for the development of textured 3D models and graphic design software that allows us to analyze and disseminate the results
