Tecniche per la misura e il monitoraggio della superficie del fondo di un modello fluviale
2009
L’impiego di modelli fluviali per lo studio delle variazioni della morfologia del fondo è un argomento oggetto di interesse nel campo dell’idrologia a causa dei molteplici fenomeni interconnessi alla evoluzione di alvei naturali. Presso il laboratorio del Dipartimento di Ingegneria Idraulica e Applicazioni Ambientali dell’Università di Palermo, già da diversi anni, viene utilizzato un modello fluviale a fondo mobile per studiare i metodi di previsione della deformazione planimetrica ed altimetrica di un alveo naturale. Le ricerche condotte nel corso degli anni sono state finalizzate a ricostruire la configurazione di equilibrio del fondo deformato per effetto del deflusso della corrente. A …
When virtual and real worlds coexist: Visualization and visual system affect spatial performance in augmented reality
2021
New visualization approaches are being actively developed aiming to mitigate the effect of vergence-accommodation conflict in stereoscopic augmented reality; however, high interindividual variability in spatial performance makes it difficult to predict user gain. To address this issue, we investigated the effects of consistent and inconsistent binocular and focus cues on perceptual matching in the stereoscopic environment of augmented reality using a head-mounted display that was driven in multifocal and single focal plane modes. Participants matched the distance of a real object with images projected at three viewing distances, concordant with the display focal planes when driven in the mu…
Ventilative cooling application in Mediterranean buildings: impacts on grid interaction and load match
2016
The concept of load matching refers to the simultaneous occurrence of loads and generation in buildings: it can be increased and optimised with modifications on both the energy demand and generation, but its pre-requisite is to guarantee passive energy efficiency. In the Mediterranean areas, a major challenge in new buildings is the increasing overheating even during mildly hot seasons. Ventilative cooling can be a potential solution to such issues and have an impact on load match in buildings and their grid interaction. The study analyses the potential of ventilative cooling to improve the load match in three different case studies in Italy. Ventilative cooling proved viable in moderately …
Restoration and Enhancement of Historical Stereo Photos
2021
Restoration of digital visual media acquired from repositories of historical photographic and cinematographic material is of key importance for the preservation, study and transmission of the legacy of past cultures to the coming generations. In this paper, a fully automatic approach to the digital restoration of historical stereo photographs is proposed, referred to as Stacked Median Restoration plus (SMR+). The approach exploits the content redundancy in stereo pairs for detecting and fixing scratches, dust, dirt spots and many other defects in the original images, as well as improving contrast and illumination. This is done by estimating the optical flow between the images, and using it …
Back to the Future: Migration, Matching and the Power Couple Phenomenon in Sweden
2014
This paper contributes to a recent and growing literature addressing the phenomenon of high-credentialed power couples. It seeks to determine the extent to which precursors of power couple formation and location choice of couples at midlife are evident in young people during their formative school years. Its second objective is to extend the analysis of location choice by modeling location choice among different sizes of labor market areas, given different power status of the couples. Based on analysis of Swedish register data, we produce evidence that power spouses evolve from the population of high achieving school age individuals, the latter identified by high academic performance during…
Camouflage in arid environments: the case of Sahara-Sahel desert rodents
2020
Deserts and semi-deserts, such as the Sahara-Sahel region in North Africa, are exposed environments with restricted vegetation coverage. Due to limited physical surface structures, these open areas provide a promising ecosystem to understand selection for crypsis. Here, we review knowledge on camouflage adaptation in the Sahara-Sahel rodent community, which represents one of the best documented cases of phenotype-environment convergence comprising a marked taxonomic diversity. Through their evolutionary history, several rodent species from the Sahara-Sahel have repeatedly evolved an accurate background matching against visually-guided predators. Top-down selection by predators is therefore …
Nonlinear Disorder Mapping Through Three-Wave Mixing
2010
We implement a simple and powerful approach to characterize the domain distribution in the bulk of quadratic ferroelectric crystals via far-field second-harmonic spectroscopy. The approach is demonstrated in a lithium tantalate sample with periodic electric field poling and random mark-to-space ratio.
Are scholarships effective in Spain? An impact assessment of the upper secondary non-tertiary level
2014
España tiene un gran reto a futuro en la gran cantidad de individuos que no finalizan sus estudios más allá de la escolarización obligatoria y que se traduce en una alta tasa de abandono escolar prematuro y una baja tasa de graduación en secundaria post-obligatoria. En este marco, el objetivo de este trabajo es identificar si la política de becas, llevada a cabo durante el período 2004-2005 en España, ha sido eficaz en su objetivo de incrementar el porcentaje de alumnos que finalizan con éxito el nivel secundario post-obligatorio. Para ello se aplicará una evaluación de impacto (ex-post) con información individual para conocer si hubo cambios en las tasas de finalización del nivel educativo…
Rayleigh Equation Anomaloscope from Commercially Available LEDs
2012
Most precise classification of CVD (color vision deficits) can be provided by using anomaloscope. Today anomaloscopes are available, which can evaluate red-green (Rayleigh) and blue-green (Moreland) color defects.DOI: http://dx.doi.org/10.5755/j01.ms.18.2.1928
Carga de comorbilidad y beneficio de la revascularización en ancianos con síndrome coronario agudo
2021
Introduction and objectives: To evaluate the interaction between comorbidity burden and the benefits of in-hospital revascularization in elderly patients with non-ST-segment elevation acute coronary syndrome (NSTEACS). Methods: This retrospective study included 7211 patients aged ≥ 70 years from 11 Spanish NSTEACS registries. Six comorbidities were evaluated: diabetes, peripheral artery disease, cerebrovascular disease, chronic pulmonary disease, renal failure, and anemia. A propensity score was estimated to enable an adjusted comparison of in-hospital revascularization and conservative management. The end point was 1-year all-cause mortality. Results: In total, 1090 patients (15%) died. Th…
