Anonymization as homeomorphic data space transformation for privacy-preserving deep learning
2021
Industry 4.0 is largely data-driven nowadays. Owners of the data, on the one hand, want to get added value from the data by using remote artificial intelligence tools as services, on the other hand, they concern on privacy of their data within external premises. Ideal solution for this challenge would be such anonymization of the data, which makes the data safe in remote servers and, at the same time, leaves the opportunity for the machine learning algorithms to capture useful patterns from the data. In this paper, we take the problem of supervised machine learning with deep feedforward neural nets and provide an anonymization algorithm (based on the homeomorphic data space transformation),…
Skeleton-Based Multiview Reconstruction
2016
International audience; The advantage of skeleton-based 3D reconstruction is to completely generate a single 3D object from well chosen views. Having numerous views is necessary for a reliable reconstruction but projections of skeletons lead to different topologies. We reconstruct 3D objects with curved medial axis (whose topology is a tree) from the perspective skeletons on an arbitrary number of calibrated acquisitions. The main contribution is to estimate the 3D skeleton, from multiple images: its topology is chosen as the closest to those of the perspective skeletons on the set of images, which means that the number of topology changes to map the 3D skeleton topology to topologies on im…

The promotion of tourism in Italian regions from a sensorial perspective: a website content analysis
2022
Recent tourism literature has identified the sensory dimension as key to understanding, planning and marketing tourist experiences. This paper aims to understand to what extent Italian regions consider the sensorial perspective in tourist communication, focusing the analysis on their institutional websites. We used the content analysis method considering two different periods to investigate the evolution of Italian tourism promotion. The results show that for all institutional websites, over time, attention engages only some of the five sensorial dimensions. That is, the communication does not appear balanced. Furthermore, the promotional communication in several regions is more oriented to…
The Ti-influence on the tourmaline color
2008
Titanium was examined in different black tourmalines by spectrophotometric analyses in the region between 12500 and 27000 cm-1 (800-370 nm) using a microscope spectrophotometer MPV-5P, Leitz (Germany), and chemically analyzed on an electron microprobe Camebax Microbeam, Cameca (France) in WDS Mode. Fourteen tourmaline samples with their face oriented parallel to the principal axis, cut and polished down to thin sections, showed polarized spectra of two broad absorption bands at approximately 14000 cm-1 (715 nm) and 24000 cm-1 (417 nm). Precision thickness measurements were used to calculate the absorption coefficients α. For the absorption around 24000 cm-1, a linear correlation was observe…
Siracusa e la Sicilia nel III secolo a.C.: problemi conoscitivi e proposte di lettura dei fenomeni urbanistici e architettonici
2017
L’evoluzione sotto il profilo urbanistico e architettonico delle città di Sicilia nel III secolo a.C. può essere compresa solo a partire da un esame delle evidenze di Siracusa, la maggiore città dell’Occidente greco-ellenistico e capitale di un regno che sotto Agatocle e soprattutto sotto Ierone II vede un prodigioso sviluppo non solo per l’estensione dell’area urbana, ma soprattutto per la riconfigurazione dello spazio cittadino in forme innovative, destinate a influenzare in maniera decisiva anche le città minori del regno e dell’Oriente dell’isola, e successivamente anche dei comprensori centro-occidentali e settentrionali. L’aspetto più importante e programmatico nella rimodulazione del…
Evaluación de los efectos producidos en diferentes niveles de organización biológica en Daphnia magna tras la exposición al fungicida procloraz y al …
2021
Desde hace décadas, el uso de plaguicidas sintéticos ha permitido optimizar el rendimiento en la producción de alimentos y continúa siendo la forma más rentable de prevenir y/o erradicar las plagas que amenazan su viabilidad y prosperidad. Lamentablemente, casi tres cuartas partes de los recursos hídricos dulceacuícolas son destinados a la producción agrícola, convirtiéndose así en una de las principales vías por la que los plaguicidas acceden al medio acuático natural. En España, dos de los plaguicidas de mayor uso son el fungicida procloraz y el insecticida piriproxifen. Ambos detectados en diferentes sistemas fluviales como los ríos Ebro, Guadalquivir, o Turia. Su llegada a estos ecosist…
Educación XX1 : revista de la Facultad de Educación
2021
Resumen basado en el de la publicación Título, resumen y palabras clave en español y en inglés El Trabajo Fin de Grado (TFG) se considera la experiencia de aprendizaje más relevante de un programa académico, de hecho, incluso se utiliza como indicador de la calidad del grado en su conjunto. Dada su relevancia, se analiza el planteamiento que realizan las universidades públicas y privadas en España de la asignatura de TFG de los grados en Maestro/a en Educación Infantil y/o Primaria, en Educación Social y en Pedagogía. Para alcanzar este objetivo se ha llevado a cabo un análisis de contenido de las 116 guías docentes de la asignatura de TFG en los grados del ámbito de la educación de las uni…
Phase equilibria of Pantelleria trachytes (Italy): constraints on pre-eruptive conditions and on the metaluminous to peralkaline transition in silici…
2018
Pantelleria Island is the type locality of pantellerite, an iron and alkali-rich rhyolite (P.I=molar Na2O+K2O/Al2O3 >1.05). Peralkaline rhyolites (i.e pantellerite and comendite) and trachytes usually represent the felsic end-members in continental rift systems (e.g., Pantelleria, Tibesti, Ethiopia, Afar, Kenya, Bain and Range, South Greenland) and in oceanic sland settings (Socorro Is., Easter Is., Iceland and Azores). The origin of peralkaline rhyolites in the different tectonic settings is still a matter of debate and three hypotheses have been suggested: (a) crystal fractionation of alkali-basalt in a shallow reservoir to produce a trachyte which subsequently gives rise to a pantelle…
EL ANUNCIO DE PERMUTA: NACIMIENTO Y DESARROLLO DE UNA TRADICIÓN DISCURSIVA
2015
En este artículo se presenta el anuncio de permutas en Cuba, en su surgimiento como una tradición discursiva que evoluciona desde la inmediatez hacia la distancia. Dado un marco escénico de dos personas con necesidades complementarias de cambio de casa, se analiza la estructura de este discurso, y los recursos con que se logra la seducción o la persuasión. También se estudia la imagen tanto del enunciador como del enunciatario, que se colige del texto. Se evidencia que en este producto comunicativo para el consumo cultural, el mensaje esencial no se refiere a las características del producto transaccional, sino a la voluntad suasoria, y al acto directivo incluido. En la voluntad de crear ex…
