Architettura emergenziale: buone pratiche esecutive
2022
This paper provides a comparative overview of different types of (temporary) shelters that have recently been used in various field locations in response to a forced displacement due to disastrous events. In particular, possible strategies useful to increase the sustainability of the humanitarian response and reduce the carbon footprint, while ensuring the adequacy and suitability of the shelters themselves, are here explored. This study investigates a systematic design framework that is often constrained by many obstacles such as the limited availability of low-cost materials, and a lack of local labour experience. To reduce the negative impact of a disaster, especially in the developing c…
Architectural technologies for life environment: passive cooling strategies in the architectures of the Mediterranean area.
2020
The Mediterranean area is a highly interesting place where various States, characterised by different people, histories, and cultures face. Reigns, religions, powers, state structures, people, nationalities, etc., everything seems to be extremely different and far. On the contrary, there are some cultural points that are much closer than they officially appear. Indeed, historically, the commercial trades between the various countries have always been highly intense and the Christian and Muslim reigns, even if in a continuous state of conflict, were reciprocally linked by deep (financial) interests. Therefore, that translated in a wide trade of goods that moved on the Mediterranean Sea acros…
Strategies for building energy retrofit in the mediterranean basin
2012
The paper focuses on passive and active strategies for achieving sustainable recovery of existing buildings in the Mediterranean Basin, in order to improve indoor comfort and reduce carbon dioxide emissions in the atmosphere. The Mediterranean Basin is characterized by relatively mild winters and very warm summers. Although Mediterranean climate conditions offer excellent opportunity for the application of alternative energy sources (eg. wind, solar, hydroelectric), they are not very applied yet. Italy and Sicily in particular, comparing to most of EU countries , hang still behind in the application of innovative techniques for sustainable design and planning, and energy retrofitting of exi…
NANO, SMART AND COMPOSITE MATERIALS IN CONSTRUCTION
2018
Si può generalmente affermare che l’industria delle costruzioni costituisca un settore capace di attivare grandi attività economiche e di spe- rimentazione, anche se spesso esso utilizzi componenti e sistemi abbastanza obsoleti, se paragonati ad altri settori industriali quali, ad esempio, quello bellico o farmaceutico. La ricerca e lo sviluppo di materiali innovativi costituiscono una priorità delle agende scientifiche di parecchie Nazioni, con investimenti - sia nel pubblico che nel privato - di diversi milioni di dollari l’anno. La scelta tra i nuovi materiali avanzati è sempre più vasta ed articolata, con una capillare attenzione rivolta sia alle prime fasi della progetta- zione che all…
ARIA...Sostenibile architettura
2019
La consapevolezza del disastro urbano e geografico de- gli ultimi decenni pone tutti i cittadini e i professionisti in particolare, in qualità di artefici consapevoli, di fronte alla necessità della rifondazione e riprogettazione della città e del suo rapporto con l’ambiente, con le risorse naturali ed energetiche. Fin dalla sua fondazione nel 2012 la Sezione di Trapani dell’INBAR ha iniziato il suo percorso di riceerca e di formazione programmando una serie di Bio-Laboratori su tematiche relative alla sostenibilità ambientale e alla Bio-Architettura. The awareness of the urban and geographical disaster of the last decades places all citizens and professionals in particular, as architec…
Rhetorical deliberation. A sustainable normativism from a Gorgianic-Aristotelian perspective
2018
Starting from the discursive turn that has characterized democracy since the 80s of the last century, our article tries to outline a form of sustainable normativism. To do this, we use a theoretical framework derived from ancient Greek rhetoric and in particular from the reflection of Gorgias and Aristotle. In our perspective, on the one hand, the Gorgianic view is a useful reminder of the role that the pursuit of power and the possibility of conflict unavoidably play in the form of argumentation specific to the public sphere, that is, deliberation. On the other hand, Aristotle, thanks to his emphasis on the link between logos and desire and his analysis of truth available in deliberative c…
Fluorogenic detection of Tetryl and TNT explosives using nanoscopic-capped mesoporous hybrid materials
2013
[EN] A hybrid capped mesoporous material, which was selectively opened in the presence of Tetryl and TNT, has been synthesised and used for the fluorogenic recognition of these nitroaromatic explosives.
Artificial Neural Networks to Predict the Power Output of a PV Panel
2014
The paper illustrates an adaptive approach based on different topologies of artificial neural networks (ANNs) for the power energy output forecasting of photovoltaic (PV) modules. The analysis of the PV module’s power output needed detailed local climate data, which was collected by a dedicated weather monitoring system. The Department of Energy, Information Engineering, and Mathematical Models of the University of Palermo (Italy) has built up a weather monitoring system that worked together with a data acquisition system. The power output forecast is obtained using three different types of ANNs: a one hidden layer Multilayer perceptron (MLP), a recursive neural network (RNN), and a gamma m…
Assessment of the Operating Temperature of Crystalline PV Modules Based on Real Use Conditions
2014
Determining the operating temperatureTcof photovoltaic panelsPVis important in evaluating the actual performance of these systems. In the literature, different correlations exist, in either explicit or implicit forms, which often do not account for the electrical behaviour of panels; in this way, estimatingTcis based only on the passive behaviour of thePV. In this paper, the authors propose a new implicit correlation that takes into account the standard weather variables and the electricity production regimes of aPVpanel in terms of the proximity to the maximum power points. To validate its reliability, the new correlation was tested on two different PV panels (Sanyo and Kyocera panels) and…
Biodegradability Prediction of Fragrant Molecules by Molecular Topology
2016
Biodegradability is a key property in the development of safer fragrances. In this work we present a green methodology for its preliminary assessment. The structure of various fragrant molecules is characterized by computing a large set of topological indices. Those relevant to biodegradability are selected by means of a hybrid stepwise selection method to build a linear classifier. This model is compared with a more complex artificial neural network trained with the indices previously found. After validation, the models show promise for time and cost reduction in the development of new, safer fragrances. The methodology presented could easily be adapted to many quasi-big data problems in R…
