Convergence-theoretic mechanisms behind product theorems
2000
Abstract Commutation of the topologizer with products, quotientness of product maps, preservation of some properties by products, topologicity of continuous convergence, continuity of complete lattices are facets of the same quest. A new method of multifilters is used to establish (in terms of core-contour-compactness) sufficient and necessary conditions for these properties in the framework of general convergences. The relativized Antoine reflector plays here an important role. Several classical results (of Whitehead, Michael, Boehme, Cohen, Day and Kelly, Hofmann and Lawson, Schwarz and Weck, Kent and Richardson, and others) are extended or refined.
El proyecto mapa escolar de Valencia: Análisis de la zonificación educativa de la ciudad de Valencia
2018
The research project Mapa Escolar de Valencia (School Map of Valencia) was born out of an agreement between the City Council and the University of Valencia in order to carry out an investigation of the compulsory education system of the city and propose, if necessary, modifications to the current school zoning. The project is structured in several research areas. An analysis of the specialized scientific literature and public policies concerning education and schooling has been done, and it is currently analysing the evolution of quantitative and qualitative data on compulsory schooling in Valencia, its school zoning, the representations of education and the school climate in the city schoo…
Application of Radio Environment Map Reconstruction Techniques to Platoon-based Cellular V2X Communications
2020
Vehicle platoons involve groups of vehicles travelling together at a constant inter-vehicle distance, with different common benefits such as increasing road efficiency and fuel saving. Vehicle platooning requires highly reliable wireless communications to keep the group structure and carry out coordinated maneuvers in a safe manner. Focusing on infrastructure-assisted cellular vehicle to anything (V2X) communications, the amount of control information to be exchanged between each platoon vehicle and the base station is a critical factor affecting the communication latency. This paper exploits the particular structure and characteristics of platooning to decrease the control information exch…
Mapping the Teaching of History of Chemistry in Europe
2016
Recent developments in the field of history of chemistry have introduced new topics, challenges, and connections to a broad range of scientific, political, cultural, economic, and environmental issues. New audiences for the history of chemistry have emerged along with new topics, protagonists, spaces, and historical narratives. This paper summarizes the main results of a recent survey to map the current situation of the teaching of history of chemistry in Europe. We review how and where history of chemistry is taught in Europe, considering not only graduate students in science programs, but also other audiences such as science teachers, and the general public. This paper also provides updat…
Anomalies from the phenomenological and geometrical points of view
2008
Chiral anomalies are reviewed according to three different points of view: the usual approach together with some phenomenological implications, the algebraic approach, and, in the end and more detailed, the geometric approach. In particular, the topological approach of the Atiyah-Singer is extended in a way which allows the treatment of all chiral anomalies within the geometric (equivariant) point of view.
Crowdboard: An Augmented Whiteboard to Support Large-Scale Co-Design
2013
Co-design efforts attempt to account for many diverse viewpoints. However, design teams lack support for meaningful real-time interaction with a large community of potential stakeholders. We present Crowdboard, a novel whiteboard system that enables many potential stakeholders to provide real-time input during early-stage design activities, such as concept mapping. Local design teams develop ideas on a standard whiteboard, which is augmented with annotations and comments from online participants. The system makes it possible for design teams to solicit real-time opinions and ideas from a community of people intrinsically motivated to shape the product/service.
Concept Maps for Comprehension and Navigation of Hypertexts
2013
Comprehension and learning with hypertexts are challenging due to the nonlinearity of such digital documents. Processing hypertexts may involve navigation and comprehension problems, leading learners to cognitive overhead. Concept maps have been added to hypertexts to reduce the cognitive requirements of navigation and comprehension. This chapter explores the literature to examine the effects of concept maps on navigation, comprehension, and learning from hypertexts. The literature review aims to elucidate how concept maps may contribute to processing hypertexts and under which conditions. In spite of the variability of concept maps used in hypertexts, some findings converge. Concept maps r…
University teaching and ICT. Materials online for training Cmap Tools
2013
En estas páginas presentamos una serie de materiales creados en un proyecto de elaboración de material de formación del profesorado universitario convocado por el Servicio de Formación Permanente de la Universitat de València. El objetivo fundamental del proyecto ha sido la creación de materiales en línea para aprender el funcionamiento del software libre Cmap Tools, elaborado por el Florida Institute for Human & Machine Cognition (IHMC). Los materiales de formación, desarrollados en la primera parte del proyecto, han consistido básicamente en la creación de vídeo tutoriales que muestran el procedimiento de descarga, instalación y las distintas utilidades del software y su aplicación a la d…
Primary Student-Teachers' Conceptual Understanding of the Greenhouse Effect: A Mixed Method Study
2011
International audience; The greenhouse effect is a reasonably complex scientific phenomenon which can be used as a model to examine students' conceptual understanding in science. Primary student-teachers' understanding of global environmental problems, such as climate change and ozone depletion, indicates that they have many misconceptions. The present mixed methods study examines Finnish primary student-teachers' understanding of the greenhouse effect based on the results obtained via open-ended and closed-form questionnaires. The open-ended questionnaire considers primary student-teachers' spontaneous ideas about the greenhouse effect depicted by concept maps. The present study also uses …
Chiralities of nodal points along high symmetry lines with screw rotation symmetry
2021
Screw rotations in nonsymmorphic space group symmetries induce the presence of hourglass and accordion shape band structures along screw invariant lines whenever spin-orbit coupling is nonnegligible. These structures induce topological enforced Weyl points on the band intersections. In this work we show that the chirality of each Weyl point is related to the representations of the cyclic group on the bands that form the intersection. To achieve this, we calculate the Picard group of isomorphism classes of complex line bundles over the 2-dimensional sphere with cyclic group action, and we show how the chirality (Chern number) relates to the eigenvalues of the rotation action on the rotation …
