Active lighting applied to three dimensional reconstruction of specular metallic surfaces by polarization imaging
2005
This thesis deals with a new automated tridimensional inspection system for specular metallic surfaces, based on polarization analysis. We first present an extension of the ‘Shape from Polarization' method for dielectric to metallic surfaces. After being reflected, an unpolarized light wave becomes partially linearly polarized, depending on the surface normal and on the refractive index of the media it impinges on. Hence, by measuring the polarization parameters of the reflected light, the surface normals are computed. The ambiguity concerning the normals orientation is solved here with a new active lighting system. Then, we describe and compare numerical methods for reconstructing the trid…
Anterolateral thigh perforator flap made by customized 3D-printing fabrication of fixed positioning guide for oromaxillofacial reconstruction:a preli…
2022
Oromaxillofacial carcinomas frequently result in serious tissue defect due to enlarged resection for treating their extensive invasion, which require challenging reconstruction. Three-dimensional (3D) printing is an advanced technology which has greatly promoted the progress of craniomaxillofacial reconstructive surgery. This present study aimed to investigate the advantages of anterolateral thigh (ALT) perforator flap manufactured by 3D printing fixed positioning guide template in curing oromaxillofacial defect. Twenty patients with oromaxillofacial defects resulted from severe primary malignant tumors were divided into experimental group assisted by digital technique (n=8) and controlled …
Influence of the Cultural Background at Small and Medium Sized-Enterprises Innovations in Regional Dimension
2017
Research background: SME’s play crucial role in economy’s development. In EU they make up 99% of all enterprises and are at the forefront of technological innovations (Kotler et al., 1999, pp. 139-140; EC 2013, p. 2; Jasińska-Biliczak, 2016, p. 30). Being the flywheel for economies (Soininen et. al., 2012, p. 614) are called “hidden champions” of 20th century. Over past few years Europe-wide anal-yses (Griffin, 2004, p. 424) have emphasised the importance of investing in SME’s. Taking into consideration that cultural environment is the background to decisions: social, managerial, development (Hofstede et al., 2011, p. 46), so inno-vations, knowledge, skills and competences as well as cultur…
Beneficios extramusicales de la música: inteligencia emocional y autoconcepto
2021
La música aporta múltiples beneficios al ser humano, sin embargo, no es una materia que ocupe un papel relevante en el ámbito educativo. Su incorporación en la escuela es relativamente reciente, y nunca ha tenido un espacio con entidad propia en el currículo escolar. Con el fin de establecer un marco diferencial entre los distintos contextos educativos que ofrecen enseñanzas musicales, en la presente Tesis se han explorado las normativas y la literatura referente a la educación musical en varios de sus ámbitos. A su vez, se ha discernido entre las posibles diferencias de IE y AM entre músicos y no músicos, y se llevó a cabo un análisis y comparativa de estas variables psicológicas entre est…
Intercultural and global dimension of textbooks – points of consideration for language teachers
2019
Biorąc pod uwagę, iż nauka języka obcego jest potencjalnie związana z kształtowaniem kompetencji globalnych i międzykulturowych, celem niniejszego artykułu jest krytyczna analiza treści związanych z różnorodnością kulturową zawartych w podręcznikach używanych do nauki języka angielskiego. Rama teoretyczna analizy jest oparta na wybranych aspektach programu ukrytego, edukacji globalnej i międzykulturowej oraz związkach między nimi a nauką języka angielskiego. Jakościowe badanie treści podręczników pozwoliło autorkom zidentyfikować główne tematy związane z różnorodnością etniczną, określone jako petrification (petryfikacja), exotization (egzotyzacja) oraz povertization (ukazywanie osób i grup…
Cooperation on Readmission in the Mediterranean Area and its Human Rights Implications
Questo lavoro analizza la ‘dimensione esterna’ delle politiche migratorie dell’Unione Europea e dei suoi Stati membri concentrandosi su strumenti, politiche e pratiche di cooperazione internazionale in materia di riammissione, rimpatrio e partenariato per la mobilità con Paesi terzi nell’area mediterranea. In particolare, lo scopo di questo studio è di analizzare criticamente le politiche europee e bilaterali in materia di riammissione, indagando da un lato il crescente ricorso a strumenti di cooperazione internazionale di tipo informale e di natura quasi-giuridica o politica, e dall’altro l’impatto di tali strumenti sul rispetto degli standard internazionali e sovranazionali di tutela dei …
Large-scale nonlinear dimensionality reduction for network intrusion detection
2017
International audience; Network intrusion detection (NID) is a complex classification problem. In this paper, we combine classification with recent and scalable nonlinear dimensionality reduction (NLDR) methods. Classification and DR are not necessarily adversarial, provided adequate cluster magnification occurring in NLDR methods like $t$-SNE: DR mitigates the curse of dimensionality, while cluster magnification can maintain class separability. We demonstrate experimentally the effectiveness of the approach by analyzing and comparing results on the big KDD99 dataset, using both NLDR quality assessment and classification rate for SVMs and random forests. Since data involves features of mixe…
The effect of the cation p-surface area on the 3D organization and catalytic ability of imidazolium-based ionic liquids
2011
The dichotomic nature of ionic liquids (ILs, simple solvents or supramolecular fluids) induced us to carry out a structural investigation of some mono-and dicationic ionic liquids using 1D and 2D NMR, resonance light scattering, and UV/Vis spectroscopy. Ionic liquids with different cation π-surface areas were used, namely [bmim][NTf2], [Bzmim][NTf 2], [Bzbim][NTf2], [p-Xyl-(bim)2][NTf 2]2, and [m-Xyl-(bim)2][NTf2] 2 [bmim = 1-butyl-3-methylimidazolium, Bzmim = 1-benzyl-3- methylimidazolium, Bzbim = 1-benzyl-3-butylimidazolium, NTf2 = bis(trifluoromethansulfonyl)imide]. In order to verify to what extent the structural investigation, coupled with the determination of solvent parameters, could…
Effetti spaziali o settoriali? Una analisi della crescita della dimensione media delle Unità Locali in Italia.
2012
Utilizzando una recente versione della shift-share con struttura spaziale, in questo contributo scomponiamo il cambiamento della dimensione media delle imprese nelle province italiane rispetto a componenti di natura sia spaziale (di regione e di vicinato) che settoriale. L?analisi, condotta con riferimento al periodo 2004-2009, mette in risalto differenze di rilievo rispetto la classe dimensionale considerata. In particolare, si registra una netta demarcazione Nord-Sud nella distribuzione provinciale degli effetti spaziali e settoriali se consideriamo le micro imprese (1-10 addetti), mentre la geografia appare molto più complessa per le piccole imprese (11-50 addetti)
Dimensiunea Economică a Strategiei Europa 2020
2012
The aim of the paper is to present the economic dimension of the Europe 2020 strategy. The new strategy of European Union, was launched on 3 march 2010, as a response for economic crisis. Considerated as a new agenda for economic problem, continue, as Lisbon strategy did, to offer a new instrument to boost growth and jobs in all EU’s country. It contains 3 key priorities: smart growth, sustainable growth and inclusive growth. The economic dimension identify 3 headline targets that EU must achive them until 2020: 75 % of the population aged 20-64 should be employed; 3% of the EU's GDP should be invested in R&D and „20/20/20” climate/energy targets. The two primary research objective are: 1. …
