    A bibliometric analysis of 10 years of research on symptom networks in psychopathology and mental health
    (Elsevier, 2022-02) Ausín, Berta; Castellanos, Miguel Ángel; González Sanguino, Clara; Heradio Gil, Rubén
    Psychopathology networks consist of aspects (e.g., symptoms) of mental disorders (nodes) and the connections between those aspects (edges). This article aims to analyze the research literature on network analysis in psychopathology and mental health for the last ten years. Statistical descriptive analysis was complemented with two bibliometric techniques: performance analysis and co-word analysis. There is an increase in publications that has passed from 1 article published in 2010 to 172 papers published in 2020. The 398 articles in the sample have 1,910 authors in total, being most of them occasional contributors. The Journal of Affective Disorders is the one with the highest number of publications on network analysis in psychopathology and mental health, followed by the Journal of Abnormal Psychology and Psychological Medicine stand out. The present study shows that this perspective in psychopathology and mental health is a recent field of study, but with solid advances in recent years from a wide variety of researchers, mainly from USA and Europe, who have extensively studied symptom networks in depression, anxiety, and post-traumatic stress disorders. However, gaps are identified in other psychological behaviors such as suicide, populations such as the elderly, and gender studies.

    Metodología de desarrollo de software basada en el paradigma generativo : realización mediante la transformación de ejemplares
    (Universidad Nacional de Educación a Distancia (España). Escuela Ténica Superior de Ingeniería Informática. Departamento de Ingeniería de Software y Sistemas Informáticos, 2007-03-30) Heradio Gil, Rubén; Cerrada, José A.; Estívariz López, José Félix
    Muchos autores consideran que el desarrollo de familias de productos, frente al construcción individual de productos aislados, es un paso decisivo hacia la realización sistemática de software y la obtención de economía de alcance. Esta tesis se adscribe a esta corriente y propone un nuevo proceso de desarrollo de familias de productos, denominados EDD (Exemplar Driven Development), que aprovecha la similitud entre los productos de una familia para construirlos por analogía. La primera actividad de EDD es la realización de un producto concreto de una familia. A continuación, se busca cómo flexibilizar este ejemplar para que satisfaga los requisitos del resto de los productos. Es decir, se trata de definir formalmente una relación de analogía que permita derivar del ejemplar los demás productos de forma automática. Por último, se obtienen los productos de la familia parametrizando la flexibilización del ejemplar. Entre las aportaciones de EDD, cabe destacar: * Abordar el desarrollo y el mantenimiento de una familia de productos mediante una estrategia sistemática e interactiva. Lo primero que se construye es un ejemplar que satisface los requisitos fijos de la familia. Después, se incorporan progresivamente cepas de flexibilización que implementa los requisitos variables. * Los requisitos fijos de una familia de productos suelen ser más estables que los requisitos variables. EDD separa la implementación de los requisitos fijos (el ejemplar) de la implementación de los requisitos variables (los módulos que flexibilizan el ejemplar). * La decisión de elaborar una familia a menudo se toma al detectar trabajo repetitivo en el desarrollo aislado de varios productos de un dominio o al identificar oportunidades de negocio en la ampliación de las prestaciones de un producto de éxito. EDD reconoce esta situación y trata de aprovecharla mediante la reutilización íntegra de un ejemplar. La tesis explora distintas maneras.

    Using IoT-Type Metadata and Smart Web Design to Create User Interfaces Automatically
    (Institute of Electrical and Electronics Engineers (IEEE), 2023-02) Chacón, Jesús; Chandramouli, Rajarathnam; Torre Cubillo, Luis de la; Chaos García, Dictino; Heradio Gil, Rubén
    The advent of the Internet of Things has generated loads of data from the devices that are now connected to the Internet. While the majority of the data corresponds to measurements done by these devices, there is a second type of information (the metadata) that provides information about the devices themselves. Most of this metadata is still underused when used at all. On the other hand, the graphical user interfaces that allow operating and/or monitoring the connected devices from a computer or smartphone, are usually programmed from zero. However, the metadata that describes the main properties of the devices (i.e., inputs, outputs, precision, range, etc.) can be used along with smart web design techniques to automatically create these interfaces. This article proposes a framework to achieve this, and presents an application example consisting of an online lab of a servo-motor.

    Customized Online Laboratory Experiments: A General Tool and Its Application to the Furuta Inverted Pendulum [Focus on Education]
    (Institute of Electrical and Electronics Engineers (IEEE), 2019-09-17) Galán, Daniel; Chaos García, Dictino; Torre Cubillo, Luis de la; Aranda Escolástico, Ernesto; Heradio Gil, Rubén
    Because of online laboratories (labs), students can perform experimental activities from their mobile devices and/or computers. This article proposes an experimentation environment (EE) that extends the capabilities of interactive online labs with scripting language support. Thus, control engineering students can specify complex experiments, avoid routine tasks, and empirically test controllers they made themselves.

    Speeding up derivative configuration from product platforms
    (MDPI, 2014-06-18) Pérez Morago, Héctor José; Adán, Antonio; Heradio Gil, Rubén; Fernández Amoros, David José
    To compete in the global marketplace, manufacturers try to differentiate their products by focusing on individual customer needs. Fulfilling this goal requires that companies shift from mass production to mass customization. Under this approach, a generic architecture, named product platform, is designed to support the derivation of customized products through a configuration process that determines which components the product comprises. When a customer configures a derivative, typically not every combination of available components is valid. To guarantee that all dependencies and incompatibilities among the derivative constituent components are satisfied, automated configurators are used. Flexible product platforms provide a big number of interrelated components, and so, the configuration of all, but trivial, derivatives involves considerable effort to select which components the derivative should include. Our approach alleviates that effort by speeding up the derivative configuration using a heuristic based on the information theory concept of entropy.

    A Pragmatic Framework for Assessing Learning Outcomes in Competency-Based Courses
    (Institute of Electrical and Electronics Engineers, 2024-01-19) Vargas, Hector; Heradio Gil, Rubén; Farias, Gonzalo; Lei,,Zhongcheng; Torre, Luis de la
    Contribution: A competency assessment framework that enables learning analytics for course monitoring and continuous improvement. Our work fills the gap in systematic methods for competency assessment in higher education. Background: Many institutions are shifting toward competency-based education, thus encouraging their educators to start evaluating their students under this paradigm. Previous research shows that structured assessment models are fundamental in guiding educators toward this adoption. Intended outcomes: An assessment model for competency-based education that is easy to adopt and use, while facilitating the application of learning analytics techniques. Application design: The new framework considerably extends a prior model we proposed three years ago. Two engineering competency-based courses used the framework for assessment. Assessment rubrics were prepared and used for evaluating and collecting the students’ data progressively, thus enabling the use of learning analytics for decision-making. Findings: Thanks to the model, (i) students received a detailed report of their achievements, including a thorough explanation and justification of the evaluation criteria; and (ii) instructors could improve the course and provide objective evidence of their actions to quality assurance agencies. As a result, the framework is presently being used in fifteen courses taught at eight different university degrees at the Pontifical Catholic University of Valparaiso (PUCV).

    Teaching Automation with Factory I/O under a Competency-Based Curriculum
    (Springer, 2022-10-22) Vargas, Hector; Heradio Gil, Rubén; Donoso, Matias; Farias, Gonzalo
    Some of the most critical competencies students need to acquire to become control engineers require performing practices under actual industrial conditions. This means that they must not only master the theoretical aspects of the discipline but also acquire skills and attitudes to face unpredictable real-world situations. Software tools such as Matlab/Simulink are widely used to train the design and validation of controllers, but they fail to provide real industrial contexts. Nowadays, there are 3D simulation tools that support recreating industrial environments to a remarkable extent, making them very attractive for university courses. Nevertheless, their application in engineering courses is scarce yet. This paper presents a methodological framework for seizing into competency-based courses one of these simulation tools, called Factory I/O. Our approach was evaluated in a master’s course on Industrial PID Control at Pontifical Catholic University of Valparaíso (PUCV) in Chile. The evaluation comprised the qualitative analysis of students’ grades over four consecutive course editions and the qualitative study of students’ opinion on Factory I/O educational value. The objectives of our evaluation were (i) testing if Factory I/O helped students develop skills hard to practice in academic contexts, such as detecting faults or recognizing the importance of having well-defined operation protocols; (ii) validating our methodology for competency-based courses; and (iii) surveying our students about Matlab/Simulink and Factory I/O strengths/weaknesses to teach control engineering. According to the results, (a) Factory I/O complements Simulink by providing an adequate virtual environment to learn the aforementioned skills; and (b) our methodology supports courses’ continuous improvement through the statistical analysis of students’ achievements at different abstraction levels.

    A bibliometric analysis of off-line handwritten document analysis literature (1990–2020)
    (Elsevier, 2022-05) Ruiz Parrado, Victoria; Vélez, José F.; Heradio Gil, Rubén; Aranda Escolástico, Ernesto; Sánchez Ávila, Ángel
    Providing computers with the ability to process handwriting is both important and challenging, since many difficulties (e.g., different writing styles, alphabets, languages, etc.) need to be overcome for addressing a variety of problems (text recognition, signature verification, writer identification, word spotting, etc.). This paper reviews the growing literature on off-line handwritten document analysis over the last thirty years. A sample of 5389 articles is examined using bibliometric techniques. Using bibliometric techniques, this paper identifies (i) the most influential articles in the area, (ii) the most productive authors and their collaboration networks, (iii) the countries and institutions that have led research on the topic, (iv) the journals and conferences that have published most papers, and (v) the most relevant research topics (and their related tasks and methodologies) and their evolution over the years.

    Exemplar driven development of software product lines
    (Elsevier, 2012-12-01) Heradio Gil, Rubén; Fernández Amoros, David José; Torre Cubillo, Luis de la; Abad Cardiel, Ismael
    The benefits of following a product line approach to develop similar software systems are well documented. Nevertheless, some case studies have revealed significant barriers to adopt such approach. In order to minimize the paradigm shift between conventional software engineering and software product line engineering, this paper presents a new development process where the products of a domain are made by analogy to an existing product. Furthermore, this paper discusses the capabilities and limitations of different techniques to implement the analogy relation and proposes a new language to overcome such limitations.

    A scalable approach to exact model and commonality counting for extended feature models.
    (Institute of Electrical and Electronics Engineers (IEEE), 2014-05-29) Fernández Amoros, David José; Heradio Gil, Rubén; Cerrada Somolinos, José Antonio; Cerrada Somolinos, Carlos
    A software product line is an engineering approach to efficient development of software product portfolios. Key to the success of the approach is to identify the common and variable features of the products and the interdependencies between them, which are usually modeled using feature models. Implicitly, such models also include valuable information that can be used by economic models to estimate the payoffs of a product line. Unfortunately, as product lines grow, analyzing large feature models manually becomes impracticable. This paper proposes an algorithm to compute the total number of products that a feature model represents and, for each feature, the number of products that implement it. The inference of both parameters is helpful to describe the standarization/parameterization balance of a product line, detect scope flaws, assess the product line incremental development, and improve the accuracy of economic models. The paper reports experimental evidence that our algorithm has better runtime performance than existing alternative approaches.
