Quantifying stenosis in renal arteriograms: a fuzzy syntactic analysis.
1999
AbstractThe introduction of fuzzy logic improves a system for the automatic quantification of renal artery lesions seen in digital subtraction angiograms. A two-step approach has been followed. An earlier system based on non-fuzzy syntactic analysis provided a clear symbolic description of the stenotic lesions. Although this system worked correctly, it did not take into account the variability and uncertainty inherent to image processing and to knowledge on the reference diameter. This system has been improved by the introduction of fuzzy logic in the representation of the reference diameter. It provides a description of the stenosis in terms of fuzzy quantities. To illustrate the benefits …
Antoine Picon: Digital Culture in Architecture
2012
Today’s explosive developments in digital technology have also affected architecture and the urban landscape. The new possibilities opened up by digital simulation have led to an increasingly strategic approach to planning, an approach based on generating scenarios, which thus represents a radical departure from traditional planning. This volume provides a profound introduction to the important role of digital technologies in design and execution. In four chapters, the author systematically examines the influence of digital culture on architecture but also on the urban landscape as well as product design. The relationship of digital architecture to the city is also an important focus.
The dual nature of mobile games: between escapism and finding a community
2021
Maģistra darbā tiek apskatīta mobilo spēļu duālā daba starp eskeipismu un komūnu (alianse S), kas tiek bāzēta BTK. Šī pētījuma ietvaros tiek skatīts kā komūna un eskeipisms sadzīvo, pastiprina un vai atrodas pretrunā viens ar otru. Galvenās izmantotās datu ievākšanas metodes ir daļēji atvērtā aptauja, daļēji strukturētas intervijas, dalība un novērojums, kā arī pētījums daļēji balstīts uz auto-etnogrāfiju. Pētījuma laikā tiek skatīts komūnas un eskeipisma koncepts un ietekme uz spēlētājiem, tostarp tiek skatīta arī pavadītā laika ietekme uz pieredzi, Covid-19 pandēmijas ietekmi un pētījumu veikšanu digitālajā vidē. Maģistra darbā tiek pamatots pieņēmums, ka mobilās spēles pašā būtībā nav ne…
Anàlisi crítica d’aplicacions de lectura per a infants: paràmetres i indicadors
2018
Les aplicacions de lectura digital infantil han evolucionat considerablement al llarg dels últims anys. Tanmateix, segueixen sent les grans oblidades en informes i estadístiques sobre la producció editorial i més encara dins del sector digital, cosa que origina un fenomen d’infoxicació en què el mediador es troba amb pocs criteris que faciliten la selecció d’aquest nou tipus de continguts. Aquesta investigació presenta els resultats de l’anàlisi de tretze aplicacions de lectura en les seues dimensions de forma i contingut. Alhora, s’hi observen trets com ara el mode d’adquisició, la privacitat, l’organització de continguts o la personalització. Finalment, reflexionarem sobre l’adequació del…

Valori pedagogici e criticità dell'elearning
2014
Cos’è un modello sostenibile? Come si connota, in particolare, un modello di formazione sostenibile? E, all’interno di questo, come si declina un modello di formazione ispirato all’elearning? Quali sono le ragioni pedagogiche ed economiche che hanno richiesto/richiedono l’utilizzo di questo approccio metodologico? Scopo di questo breve lavoro è di rispondere a questi interrogativi, privilegiando, in particolare, da una prospettiva pedagogica, la riflessione sull’elearning, oggetto, questa, spesso, di punti di vista radicalmente diversi che si situano, radicalizzando il discorso, tra una posizione fortemente contestativa della formazione online accusata di operare, spesso, forme di netta sep…
El uso de tecnología móvil y APP en educación física
2017
La literatura documenta que los educadores físicos tienen actitudes pro-tecnológicas, interés y conocimientos similares al resto de profesorado. Sin embargo, el uso de TIC, especialmente en la fase activa es menor. Esta barrera de uso se explica porque el profesorado dispone de tecnología tradicional, anclada en espacios fijos, pero se carece de tecnología móvil y portable que pueda llevarse al lugar donde se sitúa la acción: patios y gimnasios. El objetivo del estudio fue conocer qué dispositivos móviles puede usar el profesorado durante las clases y hacer una recopilación y análisis de las aplicaciones que puede utilizar para diseñar, gestionar y evaluar la docencia. Se hizo una revisión …
A quantum mechanics-molecular mechanics study of dissociative electron transfer : The methylchloride radical anion in aqueous solution
2002
The dissociative electron transfer reaction CH3Cl+e−→CH3•+Cl− in aqueous solution is studied by using a QM/MM method. In this work the quantum subsystem (a methylchloride molecule plus an electron) is described using density functional theory while the solvent (300 water molecules) is described using the TIP3P classical potential. By means of molecular dynamics simulations and the thermodynamic integration technique we obtained the potential of mean force (PMF) for the carbon–chlorine bond dissociation of the neutral and radical anion species. Combining these two free energy curves we found a quadratic dependence of the activation free energy on the reaction free energy in agreement with Ma…

Le Tombe a Tempio di Norchia: dal rilievo all’anastilosi virtuale e alla ricostruzione tridimensionale
2018
Le attività di ricerca presentate in questo contributo sono state essenzialmente finalizzate al rilievo delle facciate delle due tombe presso la necropoli dell’Acqualta e alla documentazione della porzione ovest del frontone della Tomba occidentale (sinistra), conservato al Museo Archeologico Nazionale di Firenze1275. Tali rilievi, effettuati con tecniche indirette, sono stati realizzati, oltre che come basi documentali per lo studio dei due monumenti, anche in funzione della creazione di modelli tridimensionali, che sono stati utilizzati, in particolare, per lo studio ricostruttivo e il restauro virtuale delle facciate rupestri; quest’ultimo si è basato sia sul prospetto bidimensionale che…
