Impact of integrating photovoltaic based DG on distribution network harmonics
2017
The process of integrating various distributed generation (DG) technologies in power system networks is increasing rapidly in the recent years. One major concern about the integration of DGs is their impact on network harmonics. The aim of this paper is to investigate the effects caused by the integration of photovoltaic DG in distribution networks on system harmonics. The penetration level, number of DG units, and their location are used as parameters in order to verify the effects of DG on system harmonics. Moreover, a study of single and double tuned filters is conducted as harmonics mitigation techniques. Detailed simulations using Matlab/Simulink are inserted in order to explain and ve…
Magister : revista de formación del profesorado e investigación educativa
2016
La competencia colaborativa es una herramienta muy útil para el alumnado universitario. La diversidad de ámbitos profesionales que existen hoy en día demanda unos trabajadores competentes que se adapten a una realidad laboral compleja y cambiante. En este sentido, las relaciones interpersonales cobran gran importancia al requerir la colaboración entre profesionales para conseguir un objetivo final. El presente artículo describe una propuesta de trabajo colaborativo que se llevó a cabo con el alumnado universitario del cuarto curso de Magisterio de la Universitat de València que cursaban el itinerario de especialización en Educación Musical. Collaborative competition is a very useful tool fo…
Emergent behaviors and scalability for multi-agent reinforcement learning-based pedestrian models
2017
This paper analyzes the emergent behaviors of pedestrian groups that learn through the multiagent reinforcement learning model developed in our group. Five scenarios studied in the pedestrian model literature, and with different levels of complexity, were simulated in order to analyze the robustness and the scalability of the model. Firstly, a reduced group of agents must learn by interaction with the environment in each scenario. In this phase, each agent learns its own kinematic controller, that will drive it at a simulation time. Secondly, the number of simulated agents is increased, in each scenario where agents have previously learnt, to test the appearance of emergent macroscopic beha…
Label-free wavelength and phase detection based SMS fiber immunosensors optimized with cladding etching
2018
The performance of E-SMS (Etched Singlemode-Multimode-Singlemode) optical fiber structures as immunosensors has been assessed by the implementation of antibody/antigen immunoassays. Through this procedure it has been proven that E-SMS structures are effective and suitable optical platforms for label-free biosensing. Using the phase shift and tracking the wavelength response it was found that the fabricated E-SMS devices exhibited limits of detection (LOD) down up to concentrations of 0.2mg/L of antigens in solution. This was achieved by coating the E-SMS with an antibody-based biolayer (goat IgG) that is able to determine the presence of anti-goat IgG antigen. Both a wavelength detection an…
Application of remote experiments in a secondary school using MOOC approach
2017
This paper presents first attempt to incorporate remote and virtual experiments in MOOC environment for the secondary school instruction. In case study the VISIR+ remote experiment of the WebLab-Deusto was used. The basic topic of physics “Resistors in series” was suggested for the mentioned above experiment. The open edX platform was employed to build the MOOC for the school lesson — we named it ‘micro-MOOC’. The results could be helpful for secondary school sector representatives, education instructors, parents and policy makers to respond to current and future education needs.
Medical English in Italian University Courses in Sports Sciences: Some Issues in Focus
2014
Over the last few decades, the increasingly rapid progress of medical science and technology, together with the growing importance of English as the language of international communication, has made the study of medical English a crucial segment in the curriculum of medical undergraduates. In Italy, medical topics are studied not only in medical degree courses but also in those of sports sciences. This paper focuses attention on some medical English-related issues in sports sciences degree courses in Italian universities. More precisely, the work is divided into four main parts. The first part raises the terminological question concerning the denomination of the discipline “lingua inglese”/…
Sterol Digestion in Plant Sterol-Enriched Foods: Bioaccessibility and Fermentation
2021
Plant sterol-enriched foods have proved to lower serum total and low-density lipoproteins-cholesterol concentration, so they have faced a great increase in the market over the past 20 years through accepted health claims. This chapter provides an overall and critical picture on the current knowledge and future perspectives regarding bioaccessibility and fermentation of sterols contained in plant sterol-enriched food products, particularly focused on the effect of food matrix composition, as well as different in vitro gastrointestinal digestion methodologies, and the role of microbiota in the sterol degradation. The final objective of this chapter is to evince the different aspects of the di…

Ensemble methods for item-weighted label ranking: a comparison
2022
Label Ranking (LR), an emerging non-standard supervised classification problem, aims at training preference models that order a finite set of labels based on a set of predictor features. Traditional LR models regard all labels as equally important. However, in many cases, failing to predict the ranking position of a highly relevant label can be considered more severe than failing to predict a trivial one. Moreover, an efficient LR classifier should be able to take into account the similarity between the items to be ranked. Indeed, swapping two similar elements should be less penalized than swapping two dissimilar ones. The contribution of the present paper is to formulate more flexible item…
La telecolaboración entre grupos heterogéneos en la clase de lengua extranjera
2014
[ES] En la enseñanza de lenguas extranjeras, numerosos profesores trabajan las competencias lingüísticas y comunicativas por medio de actividades que incluyen las TIC. Entre ellas, se encuentran los proyectos de telecolaboración por Internet, intercambios asincrónicos y sincrónicos, entre grupos de estudiantes pertenecientes a diferentes comunidades lingüísticas distantes geográficamente. Nuestro objetivo ha consistido en comprobar si un proyecto de telecolaboración sincrónico entre grupos heterogéneos de estudiantes, con distintos perfiles y niveles en lengua extranjera, es factible y si contribuye al desarrollo de las competencias comunicativas, intercuturales y tecnológicas.
