PID2021-125091OB-I00, A feature extraction algorithm for texture detection oriented to its implementation on embedded electronics based on a Field-Programmable Gate Array (FPGA) is proposed in this paper. Local pre-processing with smart tactile sensors can help to improve dexterity in artificial hands. Simplicity is the goal in order to achieve a hardware-friendly strategy that can be replicated and integrated with another circuitry. This is interesting, considering that tactile sensors are arrays and FPGAs are capable of parallel execution. The proposal was tested with a custom smart tactile sensor mounted on a Cartesian robot to explore different textures. A comparison with a common feature extraction approach based on the fast Fourier Transform (FFT) computation was also made. In addition, the whole procedure is implemented on a System on Chip (SoC) with the feature extraction on the embedded FPGA and a k-means classifier on an ARM core. The proposed algorithm obtains the spatial frequency components of the tactile signal but not their power. Therefore, some information is lost with respect to that provided by the FFT. Nevertheless, an 89.17% accuracy of the proposed algorithm is obtained versus 91.4% with the FFT when twelve different textures are considered, including complex and fabric textures. There is a noticeable saving in power and hardware resources. In addition, since the size of the feature vector is much smaller, data traffic and memory usage is much lower, and the classifier can be simpler., Spanish Government with a Formación de Profesorado Universitario (FPU) Grant given by the Ministerio de Ciencia, Innovación y Universidades, European Regional Development Fund (ERDF) Program Funds

El programa PIRAVI, es un programa de intervención psicoeducativa, en el que se entrenan habilidades sociales como la comunicación positiva y empatía, con mejora de la autoestima, y se realiza un abordaje emocional con favorecimiento de la capacidad de reflexión y respuesta de los sujetos. Basado en la dinámica del método Transcend, se proponen acciones que promuevan actitudes positivas de cambio en los sujetos, sobre todo en aquellos más proclives al extremismo violento. Está diseñado para ser desarrollado a través de tres sesiones, donde se realizarán actividades reflexivas, de modificación de hábitos (tanto a nivel individual como colectivo) y cooperativas, y dos tareas intersesiones, contando en total con 13 actividades. Los adolescentes deben desarrollar las habilidades básicas para afrontar las situaciones cotidianas de forma eficiente y cooperativa. Los talleres se realizan en el entorno educativo y social de referencia de los alumnos/as, para poder contar con la participación del grupo de iguales. El desarrollo de las diferentes sesiones, está complementado con un trabajo individual y colectivo en casa y en el entorno social, principalmente reflexivo y de consulta con familiares y/o convivientes y compañeros. Se pretende que los alumnos/as desarrollen la capacidad crítica y trasladen lo aprendido al entorno socio-familiar. Es importante que los padres/madres tomen conciencia del esfuerzo que realizan los menores, y participen en el desarrollo de las tareas.

Agriculture is the main driver of depletion resources worldwide, and its duty is to ensure food security within a rapidly increasing demographic and urbanization, so it is important to transi-tion to sustainable production systems. Vertical crops (VCs) can reduce the pressure on conven-tional agriculture because they save water and nutrients and increase crop yield. Therefore, this study aimed to validate a proposed predictive model (PM) to simulate water and nutrient uptake in vertical crops under greenhouse conditions. Based on the Penman-Monteith equation, PM es-timates transpiration, while nutrient uptake was estimated using the Carmassi-Sonneveld sub-model. PM was experimentally evaluated for vertically grown lettuce under Mediterranean greenhouse conditions, during spring 2023. The irrigation technique was a closed-loop fertiga-tion circuit. The experimental consisted of testing two densities (50 and 80 plants·m-2), where each unit of the experiment unit was divided into three heights (lower, medium, and upper). It performed ANOVA with a value of p < 0.05 and R2 to assess PM performance. The results sug-gest a high degree of PM, since R2 ranged from 0.6 to 0.8 for the uptake of water and nutrients. Both densities had a yield between 17-20 times higher than conventional lettuce production and significant savings in water, between 85-88%. In this sense, PM has great potential to intelli-gently manage VC fertigation, saving water and nutrients, which represents an advance towards reaching SDG 6 and SDG 12, within the 2030

Purpose - Consumer affinity may be a key factor in overcoming ethnocentric barriers and promoting a favourable attitude towards specific foreign countries and their products. However, progress in knowledge of this concept in international marketing literature has suffered from a lack of integration and analysis. The purpose of this study was to shed new light on the concept of consumer affinity based on a comprehensive systematic review of the literature, provide a critical analysis of previous research in terms of conceptual, methodological and substantive issues and problems, and offer avenues for future research. Design/methodology/approach – This structured systematic review of consumer affinity included articles published in international peer-reviewed journals from 2008 to 2021, examining key conceptual, operational and substantive aspects. Findings - This systematic review of articles on consumer affinity published over the past 14 years revealed that this line of research is a growing vibrant domain in the context of international marketing. It also showed that current knowledge of consumer affinity is characterized by theoretical inconsistencies, contradictory empirical results and scant international marketing research in the affinity domain. Originality – This article provides an overview of extant literature on consumer affinity and yields a consolidated image of its current status, as well as a research agenda that raises new questions for the academic community.
