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…
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…
Diagnosis and prognosis of cardiovascular diseases by means of texture analysis in magnetic resonance imaging
2017
Cardiovascular diseases constitute the leading global cause of morbidity and mortality. Magnetic resonance imaging (MRI) has become the gold standard technique for the assessment of patients with myocardial infarction. However, limitations still exist thus new alternatives are open to investigation. Texture analysis is a technique that aims to quantify the texture of the images that are not always perceptible by the human eye. It has been successfully applied in medical imaging but applications to cardiac MRI (CMR) are still scarce. Therefore, the purpose of this thesis was to apply texture analysis in conventional CMR images for the assessment of patients with myocardial infarction, as an …
Wie „die Neue Rechte“ den Flüchtlingsdiskurs mitprägt – ein Versuch einer wortorientierten Diskursanalyse anhand „Junger Freiheit“ und „Compact“
2019
Przyjmując założenie o aktywnej roli języka w profilowaniu rzeczywistości danego dyskursu, w niniejszym artykule ukazano charakterystyczne praktyki dyskursywne stosowane powszechnie przez media wiązane z niemiecką Nową Prawicą w ich relacjonowaniu problematyki kryzysu migracyjnego oraz uchodźców. W oparciu o wybrane płaszczyzny modelu DIMEAN analizie poddane zostały internetowe wersje czasopisma „Junge Freiheit” oraz magazynu „Compact”.
Terapia trans-cranica ad ultrasuoni focalizzati guidati da Risonanza Magnetica: studio retrospettivo di semeiotica neuroradiologica intra-operatoria
2019
SCOPO DEL LAVORO: Valutare retrospettivamente le caratteristiche di semeiotica neuroradiologica delle lesioni indotte in pazienti sottoposti a talamotomia unilaterale del nucleo Vim mediante l’utilizzo di un sistema trans-cranico ad ultrasuoni focalizzati guidati da RM (tcMRgFUS). MATERIALI E METODI: Cinquanta pazienti sono stati sottoposti a talamotomia mediante tcMRgFUS per tremore essenziale refrattario a terapia medica (n = 39) o per tremore in malattia di Parkinson (n = 11). Esaminando sequenze FRFSE T2-pesate (2mm, no gap) acquisite sia intra-operatoriamente che nel successivo follow-up RM a 48h, è stata valutata la presenza e le dimensioni delle aree lesionali concentriche precedente…
Outcome Analysis From a Multicenter Registry on Unibody Stent-Graft System for the Treatment of Spontaneous Infrarenal Acute Aortic Syndrome (MURUSSI…
2022
Purpose: This study reports the outcomes from a Multicenter Registry on unibody stent-graft system for the treatment of spontaneous infrarenal acute aortic syndrome (MURUSSIAS registry). Materials and methods: The retrospective MURUSSIAS registry included spontaneous infrarenal acute aortic dissection (IAAS) managed with the unibody stent-graft system (AFX endovascular AAA system; Endologix Inc., Irvine, California) outside the current instruction for use. IAAS considered aortic dissection (AD), intramural hematoma (IMH), and penetrating aortic ulcer (PAU). Indications to IAAS treatment were symptoms, associated dilated abdominal aorta (>3 cm), rapidly-growing (>0.5 cm/6 months) aorta…
Application of the Information Bottleneck method to discover user profiles in a Web store
2018
The paper deals with the problem of discovering groups of Web users with similar behavioral patterns on an e-commerce site. We introduce a novel approach to the unsupervised classification of user sessions, based on session attributes related to the user click-stream behavior, to gain insight into characteristics of various user profiles. The approach uses the agglomerative Information Bottleneck (IB) algorithm. Based on log data for a real online store, efficiency of the approach in terms of its ability to differentiate between buying and non-buying sessions was validated, indicating some possible practical applications of the our method. Experiments performed for a number of session sampl…
