Examining the effect of adverse weather on road transportation using weather and traffic sensors.
2018
Adverse weather related to reduced visibility caused by fog and rain can seriously affect the mobility and safety of drivers. It is meaningful to develop effective intelligent transportation system (ITS) strategies to mitigate the negative effects of these different types of adverse weather related to reduced visibility by investigating the effect of rain and fog on traffic parameters. A number of previous researches focused on analyzing the effect of adverse weather related to reduced visibility by using simulated traffic and weather data. There are few researchers that addressed the impact of adverse weather instances using real-time data. Moreover, this paper conducts comprehensive inves…
Spatio-temporal variability of fog-water collection in the eastern Iberian Peninsula: 2003-2012
2019
Abstract Among the different inputs involved in the hydrological system, fog water measured by man-made passive devices is one of the most unknown components, although it could be an additional water resource for specific environmental applications (forest restoration, forest firefighting, etc.). Focusing on the Mediterranean Iberian Peninsula, the aim of this work is to quantify fog-water collected by a 24-fog-stations network spread across three latitudinal sectors with different locations (coastal, pre-littoral and inland), and to determine the most productive sites. Measurements from the network show that distance-to-sea, latitude or elevation differences between stations are factors af…
Un approccio nello state space di un problema di controllo finanziario
2004
Nell'ambito dei metodi di sintesi che si prefiggono l’obbiettivo di ottenere un sistema a ciclo chiuso con la desiderata distribuzione di autovalori della matrice dinamica (per la nota relazione che esiste tra detti autovalori ed i modi del sistema) nel presente lavoro si propone un procedimento di sintesi applicato ad un problema di portafoglio, al fine di evidenziare l’efficacia di tali strumenti d’indagine anche in ambito finanziario.
Mappe per disegnare la geografia dei luoghi della cultura materiale e immateriale in Sicilia
2013
Premessa. Racconti, mappe, infografiche In quell’impero, l’arte della cartografia giunse ad una tal perfezione che la mappa di una sola provincia occupava tutta una città, e la mappa dell’impero tutta una provincia. Col tempo, queste mappe smisurate non bastarono più. I collegi dei cartografi fecero una mappa dell’impero che aveva l’immensità dell’impero e coincideva perfettamente con esso. Ma le generazioni seguenti, meno portate allo studio della cartografia, pensarono che questa mappa enorme era inutile e non senza empietà la abbandonarono alle inclemenze del Sole e degli inverni. Nei deserti dell’ovest sopravvivono lacerate rovine della mappa, abitate da animali e mendichi; in tutto il …

Minimization of childhood maltreatment is common and consequential: results from a large, multinational sample using the childhood trauma questionnai…
2016
Childhood maltreatment has diverse, lifelong impact on morbidity and mortality. The Childhood Trauma Questionnaire (CTQ) is one of the most commonly used scales to assess and quantify these experiences and their impact. Curiously, despite very widespread use of the CTQ, scores on its Minimization-Denial (MD) subscale-originally designed to assess a positive response bias-are rarely reported. Hence, little is known about this measure. If response biases are either common or consequential, current practices of ignoring the MD scale deserve revision. Therewith, we designed a study to investigate 3 aspects of minimization, as defined by the CTQ's MD scale: 1) its prevalence; 2) its latent struc…

Making nonlinear manifold learning models interpretable: The manifold grand tour
2015
Smooth nonlinear topographic maps of the data distribution to guide a Grand Tour visualisation.Prioritisation of data linear views that are most consistent with data structure in the maps.Useful visualisations that cannot be obtained by other more classical approaches. Dimensionality reduction is required to produce visualisations of high dimensional data. In this framework, one of the most straightforward approaches to visualising high dimensional data is based on reducing complexity and applying linear projections while tumbling the projection axes in a defined sequence which generates a Grand Tour of the data. We propose using smooth nonlinear topographic maps of the data distribution to…
Kernel manifold alignment for domain adaptation
2016
The wealth of sensory data coming from different modalities has opened numerous opportu- nities for data analysis. The data are of increasing volume, complexity and dimensionality, thus calling for new methodological innovations towards multimodal data processing. How- ever, multimodal architectures must rely on models able to adapt to changes in the data dis- tribution. Differences in the density functions can be due to changes in acquisition conditions (pose, illumination), sensors characteristics (number of channels, resolution) or different views (e.g. street level vs. aerial views of a same building). We call these different acquisition modes domains, and refer to the adaptation proble…
Least-squares community extraction in feature-rich networks using similarity data
2021
We explore a doubly-greedy approach to the issue of community detection in feature-rich networks. According to this approach, both the network and feature data are straightforwardly recovered from the underlying unknown non-overlapping communities, supplied with a center in the feature space and intensity weight(s) over the network each. Our least-squares additive criterion allows us to search for communities one-by-one and to find each community by adding entities one by one. A focus of this paper is that the feature-space data part is converted into a similarity matrix format. The similarity/link values can be used in either of two modes: (a) as measured in the same scale so that one may …
