Real-Time Power Flow Monitoring and Control System for Microgrids Integration in Islanded Scenarios
2019
This article presents an enhanced system for real-time power flow monitoring and control (PFMC) for microgrids integration in medium-voltage (MV) distribution networks. The developed solution includes both system architecture and the monitoring and control algorithms, and it has low implementation and installation costs. It is based on the use of hardware and software solutions previously proposed by the authors, i.e., a distributed measurement, a control and communication architecture, and a supervisory control and data acquisition (SCADA) software, which have been enhanced and integrated for the considered application. The SCADA implements a load flow (LF) algorithm for real-time power fl…
Distributed pedagogical leadership and generative dialogue in educational nodes
2012
The article presents practices of distributed pedagogical leadership and generative dialogue as a tool with which management and personnel can better operate in the increasingly turbulent world of education. Distributed pedagogical leadership includes common characteristics of a professional learning community when the educational actors intentionally share a common mission. There, all stakeholders take collective responsibility for students' learning. Generative dialogue is a way to negotiate in this realm in generating new knowledge and understanding. To introduce this process in practice, the article describes two Finnish learning environments where the stakeholders define, first, the c…
La realidad personal en perspectiva neurocientífica. La aportación zubiriana
2015
El artículo muestra que el concepto de persona, el tipo de realidad personal elaborado por Zubiri, constituye una importante aportación filosófica en el actual contexto de la neurociencia, porque su filosofía de la persona está conectada con las ciencias biológicas y especialmente con una concepción del cerebro humano, que es entendido como órgano de hiperformalización y proporciona la base de su nuevo concepto de inteligencia sentiente, más allá de las tradicionales concepciones de la substancia, la conciencia y el sujeto.
La intimidad corporal en la filosofía de Ortega y Gasset
2015
[EN] In the face of the social crisis of intimacy for the extimacy, in neurosciences, and its reduction to privacy in legal field, this article explains the orteguian idea of the intimacy highlighting its bodily character. This notion of intimacy, rooted in body, discovers the sentimental aspect of reality (lyricism), and also overcomes thingism and subjectivism through the analysis of the mechanism of metaphor and the capacity of entering yourself. Reality of intimacy is conceived as enforceability (executive reality), and represents an alternative to idealism, objetivism of conscience and psychological introspection.
More than experience? On the unique opportunities of virtual reality to afford a holistic experiential learning cycle
2021
Virtual reality has been proposed as a promising technology for higher education since the combination of immersive and interactive features enables experiential learning. However, previous studies did not distinguish between the different learning modes of the four-stage experiential learning cycle (i.e., concrete experience, reflective observation, abstract conceptualization, and active experimentation). With our study, we contribute a deeper understanding of how the unique opportunities of virtual reality can afford each of the four experiential learning modes. We conducted three design thinking workshops with interdisciplinary teams of students and lecturers. These workshops resulted in…
Comparative evaluation of molecular methods for the quantitative measure of torquetenovirus (TTV) viremia, the new surrogate marker of immune compete…
2019
Background Torquetenovirus (TTV) viremia is emerging as a promising tool to assess functional immune competence, to predict posttransplant immune-related complications, and eventually to customize immunosuppression. Methods In this study, 327 blood samples were tested using two real-time PCR (rtPCR) assays both targeted to the untranslated region of the TTV genome. The first assay was an in-house rtPCR developed by our group, the second one was the recently marketed TTV R-GENE assay. Results In the validation study, the TTV R-GENE showed good performances in precision and reproducibility, and sensitivity as low as 12 TTV DNA copies/mL, like previously reported for the in-house rtPCR. The Bl…

The bosonic analogs of topological insulators have been proposed in numerous theoretical works, but their experimental realization is still very rare, especially for spin systems. Recently, two-dim...
Many-particle dynamics of bosons and fermions in quasi-one-dimensional flat-band lattices
2013
The difference between boson and fermion dynamics in quasi-one-dimensional lattices is studied by calculating the persistent current in small quantum rings and by exact simulations of the time evolution of the many-particle state in two cases: expansion of a localized cloud and collisions in a Newton’s cradle. We consider three different lattices which in the tight-binding model exhibit flat bands. The physical realization is considered to be an optical lattice with bosonic or fermionic atoms. The atoms are assumed to interact with a repulsive short-range interaction. The different statistics of bosons and fermions lead to different dynamics. Spinless fermions are easily trapped in the flat…
Surface Acoustic Bloch Oscillations, the Wannier-Stark Ladder, and Landau-Zener Tunneling in a Solid
2010
We present the experimental observation of Bloch oscillations, the Wannier-Stark ladder, and Landau-Zener tunneling of surface acoustic waves in perturbed grating structures on a solid substrate. A model providing a quantitative description of our experimental observations, including multiple Landau-Zener transitions of the anticrossed surface acoustic Wannier-Stark states, is developed. The use of a planar geometry for the realization of the Bloch oscillations and Landau-Zener tunneling allows a direct access to the elastic field distribution. The vertical surface displacement has been measured by interferometry.
Mètode analític i transcendentalitat
2004
No tinc la seguretat que l'expressió «filosofia analítica» siga un rètol adient per a cap tendència, mètode o escola de l'activitat filosòfica. En un sentit molt general i potser trivial, encara que no n'estic cert, la filosofia és, del seu origen ençà, anàlisi: anàlisi del pensar i de l'ésser, i de les condicions de l'un i de l'altre. Tanmateix, només al nostre segle s'ha etiquetat una manera de fer filosofia com a «filosofia analítica», per motius no gaire clars.
