WORDY: a Semi-automatic Methodology aimed at the Creation of Neologisms based on a Semantic Network and Blending Devices
2017
In this paper, we propose a semi-automatic tool, named WORDY, that implements a methodology aimed at speeding-up the pro- cess of creation of neologisms. The approach exploits a semantic network, which is explored through the spreading activation methodology and ex- ploits three blending linguistic techniques together with a proper ranking function in order to support companies in the creation of neologisms ca- pable of evoking semantic meaningful associations to customers.
Fine Alignment of Thermographic Images for Robotic Inspection of Parts with Complex Geometries
2022
Increasing the efficiency of the quality control phase in industrial production lines through automation is a rapidly growing trend. In non-destructive testing, active thermography techniques are known for their suitability to allow rapid non-contact and full-field inspections. The robotic manipulation of the thermographic instrumentation enables the possibility of performing inspections of large components with complex geometries by collecting multiple thermographic images from optimal positions. The robotisation of the thermographic inspection is highly desirable to improve assessment speed and repeatability without compromising inspection accuracy. Although integrating a robotic setup fo…
MODELLI, TESTI, PROCESSI: UNO STUDIO COGNITIVO DELLE METAFORE DELESSICALIZZATE E D’INVENZIONE
2014
La tesi di ricerca è basata sulle metafore delessicalizzate e d’invenzione riscontrate all’interno del romanzo di lingua tedesca «Kassandra» scritto nel 1983 dalla scrittrice Christa Wolf e all’interno del racconto di lingua tedesca «Minotaurus: eine Ballade» scritto nel 1985 Friedrich Dürrenmatt. Si vogliono analizzare i processi cognitivi che stanno alla base della creazione dei due tipi di metafore. Per farlo si è scelto di utilizzare tre teorie della linguistica cognitiva: la teoria della metafora concettuale (Lakoff e Johnson, 1980 e 1999); la teoria dell’integrazione concettuale (Turner e Fauconnier, 2002) e la teoria dell’analogia (Monneret, 2004). L’analisi ci permette di comprender…
Designing biochar properties through the blending of biomass feedstock with metals: Impact on oxyanions adsorption behavior
2018
Metal-blending of biomass prior to pyrolysis is investigated in this work as a tool to modify biochar physico-chemical properties and its behavior as adsorbent. Six different compounds were used for metal-blending: AlCl3, Cu(OH)2, FeSO4, KCl, MgCl2 and Mg(OH)2. Pyrolysis experiments were performed at 400 and 700 °C and the characterization of biochar properties included: elemental composition, thermal stability, surface area and pore size distribution, Zeta potential, redox potential, chemical structure (with nuclear magnetic resonance) and adsorption behavior of arsenate, phosphate and nitrate. Metalblending strongly affected biochars' surface charge and redox potential. Moreover, it incre…
What is meant by hybridity? An investigation of hybridity and related terms in genre studies
2014
AbstractThis article is an investigation and a discussion of hybridity and related terms as used in linguistic studies of genre. The theoretical points that are made are illustrated with data from empirical research done by others and with the authors’ own data. The focus is on written texts but hybridity in spoken interaction is also discussed. The article defines the notion of genre and discusses (proto)typicality in relation to genre and hybridity. Recontextualization is also discussed. This is followed by a discussion of terms that have been used to talk about the processes of hybridity, firstly, as used in research that has mainly been done on spoken interaction. The focus then turns t…
Morphology and thermal properties of foams prepared via thermally induced phase separation based on polylactic acid blends
2012
Blends of poly-l-lactic acid with two different types of polylactic acid with different average molecular weights (50,000 and 175,000 g/mol, respectively) in different proportions (90/10, 80/20 and 70/30) were utilized in order to produce biodegradable and biocompatible scaffolds for soft tissue engineering applications. The scaffolds were produced via thermally induced phase separation starting from ternary systems where dioxane was the solvent and water the non-solvent. Morphology (average pore size and interconnection) was evaluated by scanning electron microscopy. Foams apparent density was also evaluated (porosity ranges from 87% to 92%). Moreover, a differential scanning calorimetry …
Oxazoline-containing compatibilizers for polyamide/SAN and polyamide/ABS blends
2002
Polyamide (PA) and acrylonitrile/butadiene/styrene copolymer (ABS) may appear as a mixture in the recycled plastic stream. The incompatibility of these blends results in a blend with poor mechanical properties. The aim of this work is to partially convert the nitrile groups of the acrylonitrile/styrene copolymer (SAN) into oxazoline groups by reaction with aminoethanol (AE). Such modified SAN (SAN-m) can react with the amine or carboxylic acid end groups of PA, and therefore used as compatibilizers for blends of PA with ABS. SAN-m was found to reduce the SAN-domain size in the PA/SAN-blends. The initial acrylonitrile content of SAN-m had a strong influence on the degree of conversion into o…
Poly lactic acid based foams prepared via thermally induced phase separation (TIPS): A method to tune the crystallinity
2012
Blends of Poly-L-Lactic Acid (PLLA) with two Poly-Lactic Acid (PLA) in different proportions (90/10 and 70/30) were utilized in order to produce biodegradable and biocompatible scaffolds for soft tissue engineering applications. The scaffolds were produced via thermally induced phase separation (TIPS) starting from ternary systems where dioxane was the solvent and water the non-solvent. Morphology was evaluated by Scanning Electron Microscopy (average pore size and interconnection). Moreover a DSC analysis was carried out on the as-obtained scaffold in order to obtain information about theirs thermal properties (enthalpy of melt and crystallization). The results showed that is possible to p…
Color Correction for Image Stitching by Monotone Cubic Spline Interpolation
2015
This paper proposes a novel color correction scheme for image stitching where the color map transfer is modelled by a monotone Hermite cubic spline and smoothly propagated into the target image. A three-segments monotone cubic spline minimizing color distribution statistics and gradient differences with respect to both the source and target images is used. While the spline model can handle non-linear color maps, the minimization over the gradient differences limits strong alterations on the image structure. Adaptive heuristics are introduced to reduce the minimization search space and thus computational time. Experimental comparisons with respect to the state-of-the-art linear mapping model…
Al cuore del fantastico. Ibridi da pensare nel Paleolitico
2022
Our narrative abilities go back before Chauvet. Already the ivory figure of the so-called Hohlenstein-Stadel Lion-Man, dated to about 40,000 years ago, must be regarded as the most advanced product of a hundred if not a thousand years of figurative and narrative experimentation. In order to create this hybrid figure, as well the more or less theriomorphic figures which populate caves all over the world, the human mind must have possessed developed narrative skills. All the imaginary animals found in prehistoric art and all the teratologies found in caves, presuppose a narrative, more precisely the story of a metamorphosis. In this contribution I propose an interpretation that investigates t…
