Non-invasive localization of atrial ectopic beats by using simulated body surface P-wave integral maps

2017

Non-invasive localization of continuous atrial ectopic beats remains a cornerstone for the treatment of atrial arrhythmias. The lack of accurate tools to guide electrophysiologists leads to an increase in the recurrence rate of ablation procedures. Existing approaches are based on the analysis of the P-waves main characteristics and the forward body surface potential maps (BSPMs) or on the inverse estimation of the electric activity of the heart from those BSPMs. These methods have not provided an efficient and systematic tool to localize ectopic triggers. In this work, we propose the use of machine learning techniques to spatially cluster and classify ectopic atrial foci into clearly diffe…

Tangent Measures, Densities, and Singular Integrals

1995

We introduce tangent measures in the sense of David Preiss. We discuss their applications to the density and rectifiability properties of general Borel measures in ℝ n as well as to the behaviour of certain singular integrals with respect to such measures.

Crossmodal correspondences between typefaces and food preferences drive congruent choices but not among young consumers

2022

Abstract Several studies suggest that consumers match stimuli across sensory modalities, with angular (vs. round) typefaces typically associated with sourness (vs. sweetness). Drawing on findings from the field of crossmodal correspondences, this study (N = 220) examined potential typeface effects in naturalistic settings and found that exposure to angular (vs. round) typeface increased (decreased) consumers’ preferences for sour (sweet) food but had no impact on their expectations or perceptions of these tastes. Moreover, while typeface did not have a direct effect on food choices, consumers exposed to angular (vs. round) typeface reported a greater relative preference for sour over sweet …

The Impact of Integration of Instructional Systems Technology into Research and Educational Technology

2012

This paper aims at presenting a review about instructional system technology integration in educational literature. Transitional periods of educational technology are discussed and principles of integration of instructional technology in educational technology are reviewed.

Student teachers and their attitudes towards ICT: Lessons learned from three different countries

2021

This paper explores the attitudes that student teachers in Malta, Norway, and Spain convey to digital technologies in formal educational settings as they start the 1st semester. A number of studies look at educational inclinations and employment of digital technologies (Granić & Marangunić, 2019; Ritter, 2017; Scherer & Teo, 2019). We have chosen to examine student teachers’ attitudes towards the professional use of digital technologies within a pedagogical framework. In this respect, a comparative qualitative analysis of one open-ended question that forms part of a more extensive questionnaire distributed to all participants is considered. The employed analytical lens subsequently …

Integrated design of breeding blanket and ancillary systems related to the use of helium or water as a coolant and impact on the overall plant design

2021

Currently, for the EU DEMO, two Breeding Blankets (BBs) have been selected as potential candidates for the integration in the reactor. They are the Water Cooled Lithium Lead and the Helium Cooled Pebble Bed BB concepts. The two BB variants together with the associated ancillary systems drive the design of the overall plant. Therefore, a holistic investigation of integration issues derived by the BB and the installation of its ancillary systems has been performed. The issues related to the water activation due to the 16N and 17N isotopes and the impact on the primary heat transfer systems have been investigated providing guidelines and dedicated solution for the integration of safety devices…

Confronto XRF – LIBS per la caratterizzazione chimico-fisiche dei materiali lapidei provenienti dal teatro greco-romano di Taormina

2008

Vengono messe a confronto due tecniche spettroscopiche, la fluorescenza a raggi X (XRF) e la ablazione indotta da laser pulsato (LIBS), al fine di caratterizzare la composizione chimico-fisica di materiali lapidei naturali e non provenienti dal teatro Greco-Romano di Taormina. Entrambe le tecniche permettono un’analisi integrata, offrendo la LIBS la possibilità di ottenere informazioni stratigrafiche. Verranno presentati i risultati di analisi XRF e LIBS effettuate in situ e in laboratorio sui campioni prelevati nel teatro. L’interpretazione quantitativa delle analisi LIBS è stata effettuata mediante una tecnica standarless, ossia che non richiede l’uso di standard e denominata tecnica Cali…

Percepcions al voltant del coordinador TIC als Centres Educatius Intel·ligents. Un estudi de cas

2021

Este trabajo muestra las conclusiones de un estudio que tiene por objeto de análisis al coordinador TIC de un centro educativo y las percepciones, tanto del propio coordinador como de los docentes del centro, sobre sus funciones y tareas. La peculiaridad de este caso radica en que desarrolla su actividad profesional en un centro que participa en el programa de Centros Educativos Inteligentes (CEI), clasificado como Centro de Acción Educativa Singular (CAES). Los resultados aquí obtenidos forman parte de un estudio más amplio que examina las controversias a las que se enfrentan los coordinadores TIC de los CEI, modelo de integración de las TIC paralelo al modelo 1 a 1 y que ha sido experimen…
