Architettura domestica e identità. Riflessioni sul Quartiere ellentistico-romano
2018
Dopo una breve riflessione sul concetto di identità e sull'uso (o abuso) del termine nell'ambito degli studi di archeologia. Lo studio si concentra sull'eventuale passaggio di Agrigento da un'identità greca ad una "appartenenza"romana affrontando specificamente il tema dell'architettura domestica quale uno dei migliori indicatori, accanto agli usi funerari, dell'identità, privata e collettiva.
La simulazione delle portate giornaliere di un corso d’acqua tramite modelli markoviani a stato nascosto
2008
La memoria valuta l’applicabilità dei modelli markoviani a stato nascosto (Hidden state Markov Models) per la simulazione delle portate giornaliere di un corso d’acqua. In questi modelli la variabile osservata è l’emissione di un processo markoviano con un numero discreto di stati, caratterizzato da una matrice di probabilità di transizione, che viene “ricoperto” da una certa funzione densità di probabilità. Il problema della selezione del modello consiste in questo caso nella scelta del numero di stati e del tipo di distribuzione di probabilità di appartenenza ad uno stato. Identificato il modello, la sua calibrazione consiste nella stima delle probabilità di transizione e dei parametri de…
FPI Based Hyperspectral Imager for the Complex Surfaces : Calibration, Illumination and Applications
2022
Hyperspectral imaging (HSI) applications for biomedical imaging and dermatological applications have been recently under research interest. Medical HSI applications are non-invasive methods with high spatial and spectral resolution. HS imaging can be used to delineate malignant tumours, detect invasions, and classify lesion types. Typical challenges of these applications relate to complex skin surfaces, leaving some skin areas unreachable. In this study, we introduce a novel spectral imaging concept and conduct a clinical pre-test, the findings of which can be used to develop the concept towards a clinical application. The SICSURFIS spectral imager concept combines a piezo-actuated Fabry–Pé…
Gestione delle emergenze da incendi boschivi: un sistema di supporto alle decisioni in ambiente GIS
2008
Il presente studio è finalizzato alla definizione di un insieme di modelli decisionali e di procedure per la gestione a livello pre-operativo e operativo delle risorse antincendio boschivo disponibili nel territorio regionale siciliano. Per raggiungere tali obiettivi è stata messa a punto una struttura concettuale per la definizione di un sistema di supporto alle decisioni in grado di coadiuvare i responsabili della gestione delle emergenze alle diverse scale territoriali. La sintesi dello studio è costituita dall'implementazione di un prototipo relativo ad un modulo decisionale, atto a supportare le decisioni per la dislocalzione in tempo reale di uomini e mezzi, con riferimento ad un'area…
Teachers' attitudes and self-efficacy on implementing inclusive education in Japan and Finland: A comparative study using multi-group structural equa…
2018
Abstract This study aims to explore relationships between teachers' attitudes, self-efficacy, and background variables regarding inclusive education by using a sample of 359 Japanese and 872 Finnish teachers. A multi-group structural equation modelling was conducted to find similarities and differences in how the background variables predict teachers' attitudes and self-efficacy. Experience in teaching students with disabilities had a positive effect on teachers' attitudes and self-efficacy in both countries. However, teachers' teaching career and the amount of inclusive education training affected them differently in Japan and Finland. The findings could be used to improve inclusive educat…
Dangerous relationships : biases in freshwater bioassessment based on observed to expected ratios
2018
Copyright by the Ecological Society of America The ecological assessment of freshwaters is currently primarily based on biological communities and the reference condition approach (RCA). In the RCA, the communities in streams and lakes disturbed by humans are compared with communities in reference conditions with no or minimal anthropogenic influence. The currently favored rationale is using selected community metrics for which the expected values (E) for each site are typically estimated from environmental variables using a predictive model based on the reference data. The proportional differences between the observed values (O) and E are then derived, and the decision rules for status ass…

ENVIRONMENTAL FOOTPRINT REDUCTION FOR WASTEWATER TREATMENT BY MULTI-OBJECTIVE OPTIMIZATION AND MODELLING
2020
The current challenge faced by researchers and managers is minimize the environmental footprint of wastewater treatment plants (WWTPs). To accomplish this goal, other than respect legal requirements, WWTPs must provide better responses regarding consumption of energy and resources, greenhouse gas (GHG) emissions, among others. The research hereby presented is based on the application of mathematical modelling with the aim to propose a framework for the minimization of WWTP’s environmental footprint towards optimization techniques. A literature review was held to gain knowledge regarding the main decision support systems (DSS) that are applied to WWTPs since they allow selecting the most app…
Comparison between a detailed and a simplified integrated model for the assessment of urban drainage environmental impact on an ephemeral river
2008
The benefit of integrated analysis has been demonstrated in technical literature and it is also required by the EU Water Framework Directive 60/2000, which proposes a water-quality-orientated view of the whole urban drainage system and oversees new ways of assessing its performance. Integrated models, such as any complex modelling approach, often have prohibitive data availability requirements that reduce their applicability. Moreover, widely different approaches can be applied, ranging from simple conceptual models to complex physically based ones. In the present paper, two approaches have been compared using data from an experimental catchment in Bologna ( Italy), which consists of a part…
