    Vulnerability Assessment of Learning Management Systems
    (Institute of Electrical and Electronics Engineers (IEEE), 2023-03-21) San Cristóbal Ruiz, Elio; Pastor Vargas, Rafael; Gil Ortego, Rosario; Meier,Russ; Saliah-Hassane, Hamadou; Castro Gil, Manuel Alonso
    This paper presents a vulnerability assessment of a class of web applications designed to serve educational coursework to online users. We describe the deployment landscape, the known vulnerabilities institutions must be aware of, and document how non-supervised deployment puts institutions at risk from cybercriminals.

    Smart Grid: Assessment of the past and present in developed and developing countries
    (ELSEVIER, 2017) Ponce Jara, Marcos Antonio; Ruiz Larrocha, Elena; Gil Ortego, Rosario; San Cristóbal Ruiz, Elio; Pérez Molina, Clara María; Castro Gil, Manuel Alonso; https://orcid.org/0000-0002-4450-4740
    The modern struggle to generate electricity reducing our dependence on fossil fuels and decreasing greenhouse gas emissions has found an ally in Smart Grid technology. This new trend involves a renewed perspective on how to generate, transmit, distribute and manage electricity networks, which not only helps to reduce power demand and cost, but can also improve efficiency, reliability, quality and security. This paper aims to study comprehensively the Smart Grid power system by comparing experiences and success stories from around the world. Developed countries, like the United States and those in the European Union, and developing countries, like India and Brazil, have been taken as examples of the current development and state of the Smart Grid concept. Europe and the U.S. lead the development of Smart Grids systems, while Brazil and India strongly depend on foreign technology and investment for their development in their countries. Climate change represents an extra challenge for developing countries, in addition to other issues related to economic and social advancement. Nevertheless, Smart Grids offer an array of possibilities and opportunities that work towards climate change international goals. However, state motivations and national energy resources limit the advancement of Smart Grids on this matter.

    Relevant Parameters for the Classification of Reading Books Depending on the Degree of Textual Readability in Primary and Compulsory Secondary Education (CSE) Students
    (IEEE, 2019) Gil Ortego, Rosario; Martínez Sánchez, Isabel
    This paper tries to establish the most important parameters of readability when it comes to choosing reading books for students in the second and third stages of primary and compulsory secondary education (CSE). A computational system is postulated, through data-mining techniques, capable of automatically classify reading texts by virtue of syntactic, lexical, semantics, and topological parameters regarding their overall content. The validity of this process is ensured through a careful selection by editorial experts used to accomplish the same validation task among different texts. In this paper, the results in the automatic classification of the degree of readability reached are promising; they allow to continue with a deeper investigation in this field of analysis with the purpose of progressing in the age rank studied, as well as in the text themes defining the corpus.

    Evaluation of Supply–Demand Adaptation of Photovoltaic–Wind Hybrid Plants Integrated into an Urban Environment
    (Wiley, 2019) López-Rey García-Rojas, África; Campinez Romero, Severo; Gil Ortego, Rosario; Colmenar Santos, Antonio
    A massive integration of renewable energy sources is imperative to comply with the greenhouse emissions reduction targets fixed to achieve the limitation of global warming. Nevertheless, the present integration levels are still far from the targets. The main reason being the technical barriers arising from their non-manageable features. Photovoltaic and wind sources are the widest spread, as their maturity allows generation with a high-efficiency degree. A deep understanding of facilities’ performance and how they can match the energy demand is mandatory to reduce costs and extend the technical limits and facilitate their penetration. In this paper, we present a novel methodology to evaluate how photovoltaic–wind hybrid facilities, placed in an urban environment can give generation patterns which will be able to match the demand profiles better than facilities installed individually. This methodology has been applied to a broad number of locations spread over the whole planet. The results show that with high homogeneity in terms of site weather characteristics, the hybrid facilities improve the matching up to 15% over photovoltaic plants and up to 35% over wind.

    Dynamic reconfiguration in FPAA for technical and nontechnical education in a global environment
    (Wiley, 2021) Macho Aroca, Alejandro; García Teruel, Manuel; García Loro, Félix; Baizan, Pablo; Blázquez Merino, Manuel; Sancristobal Ruiz, Elio; Díaz Orueta, Gabriel; Gil Ortego, Rosario; Castro Gil, Manuel Alonso; https://orcid.org/0000-0003-3978-0692; https://orcid.org/0000-0002-5454-456X; https://orcid.org/0000-0001-5445-2377; https://orcid.org/0000-0003-0117-8794; https://orcid.org/0000-0002-6462-9196; https://orcid.org/0000-0003-2102-977X
    Some engineering concepts have been proven to be very important not only in engineering degrees but in several areas. This knowledge is difficult to grasp under certain circumstances, and sometimes prior training is needed. This is a special challenge in full or part remote education. Simulations may help in this area, but truly experimental lab practices are crucial to grasp all the required knowledge and not only for fundamental information but for complex or indirect knowledge, where students can apply what they have learnt in classes. In this paper, we have worked on a concept to help professors and students to get new concepts in a more time-efficient and safe manner, using dynamic reconfiguration in Field-Programmable Analog Array. This solution can be easily applied to traditional or remote labs in less time than usual practices, so students can learn more in the same amount of time, especially when time is a constraint.
