Uncertainty estimation of a complex water quality model: GLUE vs Bayesian approach applied with Box – Cox transformation
2010
In urban drainage modelling, uncertainty analysis is of undoubted necessity; however, several methodological aspects need to be clarified and deserve to be investigated in the future, especially in water quality modelling. The use of the Bayesian approach to uncertainty analysis has been stimulated by its rigorous theoretical framework and by the possibility of evaluating the impact of new knowledge on the modelling estimates. Nevertheless, the Bayesian approach relies on some restrictive hypotheses that are not present in less formal methods like GLUE. One crucial point in the application of Bayesian methods is the formulation of a likelihood function that is conditioned by the hypotheses …
Uncertainty propagation throughout an integrated water-quality model
2010
In integrated urban drainage water quality models, due to the fact that integrated approaches are basically a cascade of sub-models (simulating sewer system, wastewater treatment plant and receiving water body), uncertainty produced in one sub-model propagates to the following ones depending on the model structure, the estimation of parameters and the availability and uncertainty of measurements in the different parts of the system. Uncertainty basically propagates throughout a chain of models in which simulation output from upstream models is transferred to the downstream ones as input. The overall uncertainty can differ from the simple sum of uncertainties generated in each sub-model, dep…
Introduzione
2015
Il testo introduce alcuni esiti di un'attività di studio coordinata da Andrea Sciascia e dal gruppo di lavoro composto da Gaetano Cuccia, Emanuele Palazzotto, Adriana Sarro e Luciana Macaluso nell'ambito del Programma di Ricerca dal titolo "L'architettura delle chiese in Sicilia dopo il Concilio Vaticano II (FFR 2012). Dalle riflessioni emerse sulle questioni tematiche iniziali, il gruppo di lavoro ha progressivamente maturato l’idea, di comprendere, nel campo di azione della ricerca, le influenze e le contaminazioni riscontrabili fra le architetture cultuali dell’area del Mediterraneo, estendendo il lavoro di ricerca ad altri studiosi (Valentina Acierno, Mauro Bertagnin, Tania Culotta, Giu…
Thermo-hygrometric comfort in hospital rooms conditioned by means of a primary air system and ceiling radiant panels
2008
In this work the first results of experimental research are described, which began in the 2006 summer season and is still underway, on the performance of a primary air system integrated with radiant ceiling panels that runs in the hospital rooms in the maternity ward of the Maggiore Hospital of Bologna. The choice of this kind of environment is based the fact that there is more and more attention toward literature on comfort standards that must be guaranteed in the hospital environment, due to the presence of typically weak users, both from the clinical and psychological point of view. The performance of the air conditioning system is taken into account in relation to the conditions of comf…
An energy analysis of IEEE 802.15.6 scheduled access modes
2010
Body Area Networks (BANs) are an emerging area of wireless personal communications. The IEEE 802.15.6 working group aims to develop a communications standard optimised for low power devices operating on, in or around the human body. IEEE 802.15.6 specifically targets low power medical application areas. The IEEE 802.15.6 draft defines two main channel access modes; contention based and contention free. This paper examines the energy lifetime performance of contention free access and in particular of periodic scheduled allocations. This paper presents an overview of the IEEE 802.15.6 and an analytical model for estimating the device lifetime. The analysis determines the maximum device lifeti…

Il contrasto sulla nozione di dato sensibile, sui presupposti e sulle modalità del trattamento
2017
Il saggio affronta il nodo della nozione di "dato sensibile" e dei presupposti di liceità del relativo trattamento, in un quadro di profonda incertezza nell'ambito della giurisprudenza di legittimità, anche alla luce della recente riscrittura della disciplina della protezione dei dati personali realizzata dal Regolamento europeo 679/2016
LA REGISTRAZIONE OCCULTA CURATA DA UNA PERSONA PRESENTE AL COLLOQUIO
2019
Il saggio, inserito in una collettanea in tema di investigazioni atipiche alla sua seconda edizione, analizza criticamente l’ascolto “non rivelato” da parte di un soggetto presente . Le coordinate costituzionali e convenzionali consentono di mettere in evidenza l’innegabile compressione dei diritti in rilievo e una difficoltà nell’individuazione della disciplina probatoria applicabile che si ripercuote sull’utilizzabilità processuale dei risultati dell’attività di registrazione. L'analisi è condotta su un piano evolutivo che partendo dall'inquadramento sistematico mette in luce l'evoluzione normativa e giurisprudenziale, con particolare riguardo alle aree di incidenza con la disciplina del …
Predicting depression from illness severity in cardiovascular disease patients: self-efficacy beliefs, illness perception, and perceived social suppo…
2014
Background: Many studies have investigated the relationships between cardiovascular diseases and patients' depression; nevertheless, few is still known as regard the impact of illness severity on depression and whether psychosocial variables mediate this association. Purpose: The aim of this study is to investigate the putative mediating role of illness representations, self-efficacy beliefs, and perceived social support on the relationship between illness severity and depression. Methods: A total of 75 consecutive patients with cardiovascular disease (80 % men; mean age=65.44, SD=10.20) were enrolled in an Italian hospital. Illness severity was measured in terms of left ventricular ejectio…
Self-Perceived Health, Objective Health, and Quality of Life among People Aged 50 and Over: Interrelationship among Health Indicators in Italy, Spain…
2020
It is well known that self-perceived health (SPH), even if it is a subjective health indicator, is significantly associated with objective health and quality of life (QoL) in the general population. Whether it can be considered an indicator of cognitive functioning and quality of life in the elderly is still an open issue. This study used a data-driven approach to investigate the interrelationship among SPH, non-communicable diseases (NCDs), QoL, and cognitive functioning to answer this question. The study sample included information about 12,831 people living in Italy, Spain, and Greece, extracted from the Survey on Health, Aging, and Retirement in Europe, in the year 2015. The additive Ba…
