Smart grids are designed to revolutionize the energy sector by creating a smarter, more efficient and reliable power supply network. The rise of smart grids is a response to the need for a more comprehensive and sophisticated energy system that caters to the needs of homes and businesses. Key features of smart grids include the integration of renewable energy sources, decentralized generation and advanced distribution networks. At the heart of smart grids is a sophisticated metering system, consisting of intelligent electronic (...) devices that measure energy consumption and enable two-way communication between the utility company and the consumer. The information exchanged via these devices is critical, as it includes sensitive data such as energy consumption patterns and billing information. With the rise of the Internet of Things (IoT) and Industry 4.0, the security of this information is of utmost importance. This paper delves into the security challenges faced by advanced metering infrastructure (AMI) and highlights the crucial role played by cryptography in ensuring the secure exchange of sensitive information. Cryptographic protocols such as encryption, authentication and digital signatures are essential components of a secure smart grid infrastructure. These protocols work together to ensure the confidentiality, integrity and authenticity of the information exchanged between the utility company and the consumer. (shrink)

As opposed to Descartes, and in accordance with authors such as Nietzsche, Darwin or Chomsky, Pinker sustains that language is just another instinct of human nature. But he differs himself from Chomsky by affirming that language is also the result of the mechanism of natural selection. Recent discoveries seem to strengthen Pinker’s thesis, in as far as it has been possible to establish a link between the FOXP2 gene and language. Philosophy should take good note of these results, as they (...) fully affect the status of lógos: from now on, it is possible, without needing to resort to any type of transcendence, to consider language as constitutive of human singularity regarding other species and, at the same times, as just another avatar in the evolution of the natural world.

Solo el atrevimiento característico de la sabiduría nos impulsa a tomar el camino más complejo de pensar en el amor, pues nos hace conscientes del error de querer construir lo principal de la existencia en un sentimiento blando como la arena, incapaz de resistir cualquier contradicción de importancia. Encontrar el auténtico fundamento de esa pregunta, que en la actualidad no se puede dar por descontado, es la única manera de edificar la casa del hombre sobre roca, y apartarnos de la (...) necedad de levantar un edificio sin cimientos. Es una elección trascendental que, como el Papa Benedicto XVI ha señalado con fuerza, tiene una repercusión social de máximo relieve. (shrink)

La primera propuesta ética de corte aristotélico unía la racionalidad práctica con la búsqueda de un bien supremo que constituye la felicidad del hombre, realidades éticas fundamentales que iluminan la experiencia moral más básica. La racionalidad ética moderna, por un influjo neoestoico, ha volcado una sospecha respecto de esta propuesta por considerarla inadecuada para responder a una ética universal con la dificultad añadida de determinar la felicidad del hombre, por lo que ha centrado toda la visión ética en la relación (...) ley-conciencia. La revisión de la perspectiva cristiana testimoniada por San Agustín, San Máximo el Confesor y Santo Tomás de Aquino responde a estas preguntas por la emergencia de la referencia cristológica como universal concreto de la experiencia cristiana manifestado en el Amor de Cristo.

Nowadays, batteries play an important role in a lot of different applications like energy storage, electro-mobility, consumer electronic and so on. All the battery types have a common factor that is their complexity, independently of its nature. Usually, the batteries have an electrochemical nature. Several different test are accomplished to check the batteries performance, and commonly, it is predictable how they work depending of their technology. The present research describes the hybrid intelligent system created to accomplish fault detection over a (...) Lithium Iron Phosphate—LiFePO4 power cell type, commonly used in electro-mobility applications. The approach is based on the cell temperatures behaviour for voltage and current specific values. Taken into account the operating range of a real system based on a LiFePO4 cell, a large set of points of operation have been used to achieve the dataset. The different behaviour zones have been obtained by clustering as a first step. Then, different regression techniques have been used over each cluster. Polynomial regression, artificial neural networks and support vector regression were the combined techniques to develop the hybrid intelligent model proposed. The intelligent system gives very good results over the operating range, detecting all the faults tested during the validation. (shrink)

The relationship between ethics and performance has previously been addressed in the literature, although there are still some gaps, for example, the relationship of ethical ideologies to student performance. This work aims to contribute to the literature with a statistical evaluation using partial least squares path modelling (PLS-PM) regarding whether university students’ ethical ideologies and moral meaningfulness influence their level of student performance and academic achievement. Results indicate that the ideologies of justice and deontology increase moral meaningfulness, moral meaningfulness in (...) turn increase student’s citizenship behaviours and student’s in-role performance, and finally, student’s in-role performance positively influences academic achievement. This research provides resources applicable to the fields of pedagogy and ethics to encourage performance during the study and highlight the value of the ideologies of justice and deontology.

La relación entre el fenómeno religioso y el marco de la secularidad o la postsecularidad se hace presente en el ámbito de la escuela pública y, en cierta medida, reproduce las tensiones que tiene la sociedad a la hora de situar esa relación. El objetivo de este texto es presentar y valorar esa relación en el caso español, el cual posee un modelo de tipo confesional de la enseñanza de la religión en la escuela pública. La descripción del modelo debe (...) tener en cuenta el contexto histórico particular y su aplicación, que ha tenido variaciones significativas a lo largo del período democrático según los gobiernos de turno. Se trata de una opción muy controvertida que requiere una valoración ponderada, de tal manera que el texto sumaría los aspectos positivos y las dificultades que suscita el modelo en general y, en particular, la concreción española. La controversia tiene aspectos más coyunturales y otros de mayor calado, cuyo tratamiento sugiere una reflexión de tipo antropológico y teológico, la cual se realiza de manera incipiente. (shrink)

A large part of technological advances, especially in the field of industry, have been focused on the optimization of productive processes. However, the detection of anomalies has turned out to be a great challenge in fields like industry, medicine or stock markets. The present work addresses anomaly detection on a control level plant. We propose the application of different intelligent techniques, which allow to obtain one-class classifiers using real data taken from the correct plant operation. The performance of each classifier (...) is assessed and validated with real created faults, achieving successful overall results. (shrink)

This work focuses on the application of machine learning techniques to assist the clinicians in the administration of analgesic drug during general anaesthesia. Specifically, the main objective is to propose the basis of an intelligent system capable of making decisions to guide the opioid dose changes based on a new nociception monitor, the analgesia nociception index. Clinical data were obtained from 15 patients undergoing cholecystectomy surgery. By means of an off-line study, machine learning techniques were applied to analyse the possible (...) relationship between the analgesic dose changes performed by the physician due to the hemodynamic activity of the patients and the evolution of the ANI. After training different classifiers and testing the results under cross validation, a preliminary relationship between the evolution of ANI and the dosage of remifentanil was found. These results evidence the potential of the ANI as a promising index to guide the infusion of analgesia. (shrink)

We propose an extension of answer sets, that we call safe beliefs, that can be used to study several properties and notions of answer sets and logic programming from a more general point of view. Our definition, based on intuitionistic logic and following ideas from D. Pearce [Stable inference as intuitionistic validity, Logic Programming 38 79–91], also provides a general approach to define several semantics based on different logics or inference systems. We prove that, in particular, intuitionistic logic can be (...) replaced with any other proper intermediate logic without modifying the resulting semantics. We also show that the answer set semantics satisfies an important property, the “extension by definition”, that can be used to construct program translations. As a result we are able to provide a polynomial translation from propositional theories into the class of disjunctive programs. (shrink)

Automatic control of physiological variables is one of the most active areas in biomedical engineering. This paper is centered in the prediction of the analgesic variables evolution in patients undergoing surgery. The proposal is based on the use of hybrid intelligent modelling methods. The study considers the Analgesia Nociception Index to assess the pain in the patient and remifentanil as intravenous analgesic. The model proposed is able to make a one-step-ahead prediction of the remifentanil dose corresponding to the current state (...) of the patient. The input information is the previous remifentanil dose, the ANI variable and the electromyogram signal. Modelling techniques used are Artificial Neural Networks and Support Vector machines for Regression combined with clustering methods. Both training and validation were done with a real dataset from different patients. Results obtained show the potential of this methodology to calculate the drug dose corresponding to a given analgesic state of the patient. (shrink)

One of the main challenges in medicine is to guarantee an appropriate drug supply according to the real needs of patients. Closed-loop strategies have been widely used to develop automatic solutions based on feedback variables. However, when the variable of interest cannot be directly measured or there is a lack of knowledge behind the process, it turns into a difficult issue to solve. In this research, a novel algorithm to approach this problem is presented. The main objective of this study (...) is to provide a new general algorithm capable of determining the influence of a certain clinical variable in the decision making process for drug supply and then defining an automatic system able to guide the process considering this information. Thus, this new technique will provide a way to validate a given physiological signal as a feedback variable for drug titration. In addition, the result of the algorithm in terms of fuzzy rules and membership functions will define a fuzzy-based decision system for the drug delivery process. The method proposed is based on a Fuzzy Inference System whose structure is obtained through a decision tree algorithm. A four-step methodology is then developed: data collection, preprocessing, Fuzzy Inference System generation, and the validation of results. To test this methodology, the analgesia control scenario was analysed. Specifically, the viability of the Analgesia Nociception Index as a guiding variable for the analgesic process during surgical interventions was studied. Real data was obtained from fifteen patients undergoing cholecystectomy surgery. (shrink)

Background: The first wave of the COVID-19 pandemic caused a shortage of qualified nurses in Spain. As a result, the government authorized the hiring of senior students. Objectives: To explore the ethical dilemmas and ethical conflicts experienced by final-year nursing students who worked during the first outbreak of the COVID-19 pandemic in Spain. Research design: A qualitative exploratory study was conducted using purposive sampling. Semi-structured interviews were carried out using a question guide. Interviews took place via a private video chat (...) room platform. A thematic, inductive analysis was performed of the information gathered. Participants and research context: Eighteen nursing students were recruited from two universities of Madrid, aged between 18 and 65 years old, enrolled in the fourth year of nursing studies and who were hired under a relief contract for health professionals during the pandemic. Ethical considerations: The present study was carried out in accordance with the Declaration of Helsinki, and the study was approved by the Local Ethics Committee of Universidad Rey Juan Carlos. Results: Three specific themes emerged: (a) coping with patient triage, (b) difficulties in providing end-of-life care, and (c) coping with patient death. Nursing students participated in the process of patient selection for resource allocation and ICU bed occupancy. They were shown how to care for patients who were not admitted to the ICU, in their last moments and were faced with the difficulties of applying end-of-life care. Finally, the nursing students were confronted with the death of their patients, in overwhelming numbers and under adverse conditions. Conclusions: These findings can help shed light on the ethical dilemmas and ethical conflicts faced by novice nursing students, incorporated into the workforce during the COVID-19 pandemic. Moreover, it was described that students may normalize the death due to the exhaustion and overwhelmed routine. (shrink)

Closed-loop administration of propofol for the control of hypnosis in anesthesia has evidenced an outperformance when comparing it with manual administration in terms of drug consumption and post-operative recovery of patients. Unlike other systems, the success of this strategy lies on the availability of a feedback variable capable of quantifying the current hypnotic state of the patient. However, the appearance of anomalies during the anesthetic process may result in inaccurate actions of the automatic controller. These anomalies may come from the (...) monitors, the syringe pumps, the actions of the surgeon or even from alterations in patients. This could produce adverse side effects that can affect the patient postoperative and reduce the safety of the patient in the operating room. Then, the use of anomaly detection techniques plays a significant role to avoid this undesirable situations. This work assesses different one-class intelligent techniques to detect anomalies in patients undergoing general anesthesia. Due to the difficulty of obtaining real data from anomaly situations, artificial outliers are generated to check the performance of each classifier. The final model presents successful performance.

Trait emotional intelligence (“trait EI”) concerns our perceptions of our emotional abilities, that is, how good we believe we are in terms of understanding, regulating, and expressing emotions in order to adapt to our environment and maintain well-being. In this article, we present succinct summaries of selected findings from research on (a) the location of trait EI in personality factor space, (b) the biological underpinnings of the construct, (c) indicative applications in the areas of clinical, health, social, educational, organizational, and (...) developmental psychology, and (d) trait EI training. Findings to date suggest that individual differences in trait EI are a consistent predictor of human behavior across the life span. (shrink)

This article is part of the period of methodological expansion, proposed by the philosopher Arturo Roig (1922-2012), in the 70's and 80's. Although the analysis of categories is rooted in the philosophical field, this expansion is made in the direction of social categories. More specifically to the categories of “civilization” and “barbarism”, both in the field of the history of ideas and in the philosophical history of Latin American liberation. First, we give different definitions and their multiple uses of category (...) in philosophy. Subsequently, we analyze the category of “human dignity”, one of the arms of the very broad anthropological a priori category, systematized by the thinker from Mendoza. Then we disaggregate the proposal of a categorical rearmament, which has among its multiple functions: the rescue, criticism, replacement, reworking and integration of categories that have been forgotten, distorted, dehistoricized and decontextualized. The categories of “civilization” and “barbarism” have generated a semantic ordering of the discursive universe in Latin America. We review different theses proposed by Roig, in the historicization of the assessment -both negative and positive- of the category “barbarism” that different thinkers in Latin America have expressed. Among them: Juan Montalvo, Domingo Faustino Sarmiento, José Hernández, Juan Bautista Alberdi, Ezequiel Martínez Estrada, among the main ones. (shrink)

This article presents three studies examining the importance of identification with characters in research on media entertainment. In Study 1 it was found that identification with characters was associated with spectators' degree of enjoyment of feature films of different genres. Study 2 showed that identification with characters predicts the affective impact of a dramatic film and, also, it was associated with greater cognitive elaboration and a more complex reflexive process during the viewing of the dramatic film. In Study 3 it (...) was observed that identification with characters predicted the incidental impact of a full length fictional film on attitudes and beliefs. These results support the centrality of the construct of identification with characters in narrative persuasion research. (shrink)

Este artículo estudia, desde un punto de vista analítico, la teoría de la percepción que AndrésBello presenta en su Filosofía del Entendimiento. El objetivo central consiste en elucidar cuáles sonlos elementos que componen y estructuran el proceso de la percepción. En este sentido, se procedemediante el análisis de los capítulos y los apéndices relacionados con los temas de la percepción, quecorresponden con la primera parte denominada, “Psicolojía mental”. De conformidad con lo anterior,se analizan las nociones de alma o espíritu, conciencia, (...) sensación, intuición, referencia o juicio, eimpresión. Metodológicamente, se recurre a las estrategias y recursos que para el trabajo filosóficoprovee el análisis del lenguaje. Finalmente, se concluye que la teoría de la percepción en Andrés Bello,involucra la colaboración de una serie de subprocesos como la intuición, la sensación y la referencia ojuicio, además de reclamar como indispensable la unidad e indivisibilidad del alma o el “yo”.

El panteísmo de Baruch de Spinoza se convirtió en el estandarte de la cosmovisión filosófica que el autor desarrolló, lo que ha hecho que, al tratarse de éste, se le asocie con su peculiar concepción de Dios y cómo ésta está relacionada con la felicidad del hombre. Es por dicha razón que busco retomar la importancia de una concepción panteísta/spinoziana adecuada a la realidad de nuestro contexto histórico. Si bien hay un abanico muy amplio de concepciones teológicas y cultos que (...) de éstas se siguen, considero que la visión que Baruch de Spinoza sostenía de Dios tiene una relevancia vigente si se la aborda por sus postulados principales después de considerar los cambios contextuales y adoptarlos dentro del contexto actual.

En nuestros días se vuelve normal seguir observando comportamientos negativos y con recriminaciones hacia al sexo femenino, se sigue viviendo con una cierta desvalorización de la mujer en la sociedad actual, lo cual no debería ser así, esto por supuesto es un problema con el que se ha tenido que luchar por muchos años, desde Simone de Beauvoir y su visión feminista se ha logrado identificar cuáles han sido las principales bases en las que se ha basado el sistema patriarcal, (...) y en conjunto con ello se ha analizado para conocer de fondo cual o donde debería estar la solución para erradicar este problema, con esto se ha avanzado en gran medida para obtener una cierta libertad e independencia de la mujer. Es importante conocer las bases del feminismo, desde la primera ola y el giro que le dio la filósofa francesa de Beauvoir, pues además de integrar la lucha por los derechos y un estatus social que les permitiera participar activamente en sociedad que les pertenecía a todas las mujeres desde su nacimiento, se conoce y reflexiona como la mujer también ha tenido que dejar a un lado su miedo y el comportamiento indiferente o de resignación frente a todo lo que vivían cada una de ellas desde aspectos y clases sociales diferentes, es claro que las clases sociales también fueron y siguen siendo un aspecto que ha llevado a la mujer a la situación en la que se encuentra hoy en día, pues quienes han tenido un mayor acceso a la educación y conocer sobre el mismo feminismo las ha llevado a considerar su vida de otra forma y esto las ha ayudado a construirse y sobre todo a poner metas que las han conducido a pensar en una vida diferente, sin opresiones, desde su mismo sexo, hasta el sexo masculino.

En su análisis del significado literal Searle ha utilizado el principio de que al llevar a cabo un acto de habla el significado literal de las expresiones proferidas deja indeterminado el contenido de este acto. Se argumenta que este principio, además de entrar en conflicto con ciertas intuiciones lingüísticas, conduce a análisis poco naturales de fenómenos como los de la existencia de constituyentes no articulados y de la transferencia semántica. Finalmente, se alega que una combinación de ideas de Wittgenstein y (...) Drestke permite proporcionar mejores explicaciones de esos fenómenos. (shrink)
