DA PLOP A YIUK YIUK: ONOMATOPEE, IDEOFONI E INTERIEZIONI NE "LE JOURNAL DE MICKEY", "PICSOU" E "TOPOLINO" DAGLI ANNI TRENTA AGLI ANNI SETTANTA
2017
The purpose of this paper is a quantitative and qualitative investigation into the study of onomatopoeic sounds, which can be uncovered in the French and Italian versions of Mickey Mouse. This survey will take place through a comparison between the French and Italian stories and, at the same time, by a focus on onomatopoeic sounds as the concrete signs of the use of informal language. French Corpus: Le journal de Mickey from 1934 (number 1) to 1937 (7 numbers) and Picsou (from 1977 to 1984), about 60 stories.Italian Corpus; Nel Regno di Topolino from 1936 to 1939 (8 comics) and Topolino (from 1977 to 1979, 8 comics) about 70 stories.
Grouping
2020
Grouping refers to the function of unification and segregation due to factors which account for the fact that the perception of the environment is endowed with order, structures and filled with objects and events among which relations of connection or disjointness hold. Gestalt psychologists provided a wealth of experimental evidence for the specification of the factors and their phenomenological nature, that is their independence from non-perceptual determinants. grouping factors can be discovered through well-defined transformations applied on elements and specified recursively as functional connections. They figure as preferential rules of perceptual grammar.
Second sound propagation in laminar and turbulent superfluid 4He via extended thermodynamics
2012
In this work, previous results on the complex propagation of second sound in laminar and turbulent superfluid 4He are reported. Furthermore the case of inhomogeneous superfluid turbulence is examined and, in particular, the wave propagation is investigated in the presence of an anisotropic vortex tangle. Two cases of physical interest are considered: wave front collinear and orthogonal to the heat flux.
3D simulations of microquasar jets in clumpy stellar winds
2011
High-mass microquasars consist of a massive star and a compact object, the latter producing jets that will interact with the stellar wind. The evolution of the jets, and ultimately their radiative outcome, could depend strongly on the inhomogeneity of the wind, which calls for a detailed study. The hydrodynamics of the interaction between a jet and a clumpy wind is studied, focusing on the global wind and single clump-jet interplay. We have performed, using the code \textit{Ratpenat}, three-dimensional numerical simulations of a clumpy wind interacting with a mildly relativistic jet, and of individual clumps penetrating into a jet. For typical wind and jet velocities, filling factors of abo…
The Mach cone signal and energy deposition scenarios in linearized hydrodynamics
2010
Particle correlation measurements associated with a hard or semi-hard trigger in heavy-ion collisions may reflect Mach cone shockwaves excited in the bulk medium by partonic energy loss. This is of great interest because, when compared with theory, such measurements can provide information on the transport properties of the medium. Specifically, the formation of Mach cone shockwaves is sensitive to the viscosity and speed of sound, as well as the detailed nature of the jet medium interaction. However, modeling the physics of shockwave excitation to obtain a meaningful comparison with the measured correlations is very challenging since the correlations arise from an interplay of perturbative…
A geophysical and geochemical approach for seawater intrusion assessment in the Acquedolci coastal aquifer (Northern Sicily)
2007
Vertical electrical sounding (VES’) surveys and chemical analyses of groundwater have been executed in the coastal plain of Acquedolci (Northern Sicily), with the aim to circumscribe seawater intrusion phenomena. This urbanized area is representative of a more general problem interesting most of Mediterranean littoral areas, where intensive overdraft favors a heavy seawater intrusion through the coastline. Aquifer resistivity seems decisively to be conditioned by the chlorine and magnesium content in the main aquifer of the region. Schlumberger VES’, together with piezometric and chemical–physical information of groundwater, allowed us to perform hydrogeological and geophysical elaborations…
Occiput-spine relationship: shoulders are more important than head.
2017
BACKGROUND:To understand the role of fetal spine position in determining a fetal head position at the time of birth and modality of delivery. PATIENTS AND METHODS: This was a multicenter prospective observational study. Fetal occiput and spine position were evaluated by intrapartum ultrasound. Eighty-six women were eligible for inclusion in the study. Occiput rotational movements and modality of delivery in relation to the fetal spine position were investigated. RESULTS: At the beginning of labor, fetal occiput was in a posterior position in 52.3% of cases and, in 81.5% of cases the spine was in an anterior transverse position. At birth, occiput and spine were both in an anterior position i…
Deep Gaussian processes for biogeophysical parameter retrieval and model inversion
2020
Parameter retrieval and model inversion are key problems in remote sensing and Earth observation. Currently, different approximations exist: a direct, yet costly, inversion of radiative transfer models (RTMs); the statistical inversion with in situ data that often results in problems with extrapolation outside the study area; and the most widely adopted hybrid modeling by which statistical models, mostly nonlinear and non-parametric machine learning algorithms, are applied to invert RTM simulations. We will focus on the latter. Among the different existing algorithms, in the last decade kernel based methods, and Gaussian Processes (GPs) in particular, have provided useful and informative so…
Study of 3D sound for an audio-visual interaction in enriched virtual environment
2011
Most of the applications integrating 3D sound in virtual environment are limited to acoustic simulation. The objective of this thesis is to study the added value of 3D sound in the interaction with virtual environment. We developed an audio stimulation technique called "Artificial Spatial Audio Sensation: (ASAS)" based on the creation of audio effects. This technique conveys the sensations of spatialized sound that allows accurate sound source localization in azimuth and in elevation. In order to improve the localization time we also developed a model that integrates Head-Related Transfer Function (HRTF) with the ASAS technique. For the simulation of the depth of spatial sound sources, we d…
Age differences in the irrelevant sound effect: A serial recognition paradigm
2015
In adults, the disrupting effect of irrelevant background sounds with distinct temporalspectral variations (changing-state sounds) on short-term memory performance was found to be robust. In the present study, a verbal serial recognition task was used to investigate this so-called Irrelevant Sound Effect (ISE) in adults and 8- to 10-year-old children. An essential part of the short-term memory impairment during changing-state speech is due to interference processes (changing-state effect) which can be differentiated from the deviation effect of auditory distraction. In line with recent findings (Hughes et al., 2013), our study demonstrates that the changing-state effect is not modulated by …
