A Sustainable and Zero Energy Healthcare Facility in Mozambique
2016
Sustainable urban development, especially in economically disadvantaged regions, has increasingly become a major strategic priority. New settlements and urban regeneration programs have to improve the quality of social life, promote economic growth, increase environmental protection practices, and ensure the appropriate use of local resources. In that framework, a well-structured healthcare service is commonly conceived as vital for urban development. In response, this paper proposes the construction of one such healthcare facility in a deprived urban area in Maputo, Mozambique. Prioritising typical pillars of sustainability, the project’s design considers traditional building typology and …
Multi-Agent Systems as Effective Tools for the User-Based Thermal Comfort: an Introduction
2010
Through the paper the characterization of a comfort model, enriching that proposed by Fanger with an adaptive approach, is carried out using a Multi Agent System (MAS). This is a well suited coordinated set of Intelligent Agents, that are software applications interacting in order to follow user in his own needs and preferences in relation to indoor comfort, adapting to the changes of context variables. As a matter of fact, MAS are systems aware of the scenery where users live, following them in their own needs and preferences and adapting to their expectations. Indeed, thermal comfort conditions in the built environment are strictly related not only to the thermal and geometric building fe…
Experimental study on the efficiency of ceiling radiant panels used for air conditioning in hospitals.
2008
La presente memoria descrive i risultati dei primi sei mesi di una ricerca relativa allo studio sperimentale delle prestazioni energetiche, di comfort e di qualità microbiologica dell'aria in degenze ospedaliere climatizzate mediante impianti ad aria primaria e sistemi radianti a soffitto. Lo studio è stato sviluppato grazie alla collaborazione tra le Università di Ferrara, Bologna e Palermo, l'Azienda USL di Bologna e la Proter Imex di San Pietro di Feletto, azienda produttrice di sistemi radianti a soffitto. Le indagini sono in corso a partire dalla stagione estiva del 2007 e sono state condotte installando nell'ambiente campione, ubicato all'interno del reparto Maternità dell'Ospedale Ma…
Integrated analysis of performances of facades for indoor comfort purposes
2002
Some guidelines for a method able to evaluate different physical characteristics of building facades, equipped with glazed surfaces, and of indoor environments in order to attain indoor comfort conditions are proposed. New graphs are introduced, showing at the same time the behaviours of several technical-physical parameters of walls, in order to allow comparative analysis of different design configurations in terms of acoustics, lighting and heat transfer properties. Similar graphs are also constructed with reference to parameters characteristic of indoor environment, in order to allow synthetic analysis of comfort conditions. The method would represent a contribution toward the definition…
RESEARCH ON MICROCLIMATE LIGHT CONDITIONS IN A SCHOLASTIC ENVIRONMENT, BASED ON ADAPTIVE MODEL
2010
This paper shows the results of a deep research, carried out on a scholastic setting and based on a questionnaire, to evaluate the light microclimate and the satisfaction degree of the users. Through simulations, we have previously identified a number of classrooms where the conditions could be critical, both in terms of over-lightning, glare and disrespected values (suggested by the current normative). The proposed method consist in using device-made-surveys, a simulation software and questionnaires submission to users of the studied rooms. The questionnaires, based on an adaptive model, has been developed to detect subjective data (place, visus…) and other information about the setting an…
Alcuni indici per la valutazione dei sistemi di controllo per l’illuminazione
2018
Gli edifici smart hanno visto negli ultimi anni una sempre più ampia diffusione. Per questo motivo ricercatori, progettisti e tecnici, hanno posto una crescente attenzione sull’utilizzo di sistemi di controllo automatici per l’illuminazione. Questa tipologia di sistemi gioca, infatti, un ruolo chiave nel raggiungimento di significativi riduzioni dei consumi elettrici e dei benefici legati all’utilizzo della luce naturale (ad esempio il comfort visivo degli occupanti, il benessere e la produttività). È prassi comune, durante la fase progettuale, correlare il risparmio energetico con la disponibilità della luce diurna, poiché risulta un obiettivo rilevante per progettisti e architetti.
Modulate research effort in inbound alliance
2014
We address the R&D supply chain where a customer wants to sign an R&D contract with a supplier in an inbound open innovation style. Supplier has to decide how much effort put on contract: effort is assumed as nonobservable then it cannot be constrained contractually. We model the R&D process like a staged one, which allows for both an early contract and a late one. The overall committed effort depends on the alliance timing: earlier contracts will ask for a greater cumulated effort although they offer risk-sharing opportunity. On the other hand, later contracts see supplier with a stronger ex-ante bargaining power position, due to shorter (and then less risky) contract length and experience…
Symbolic Programming of Distributed Cyber-Physical Systems
Cyber-Physical Systems (CPSs) tightly integrate physical world phenomena and cyber aspects of computational units. The composition of physical, computational and communication systems demands different levels and types of abstraction as well as novel programming methodologies allowing for homogeneous programming, knowledge representation and exchange on heterogeneous devices. Current modeling approaches, frameworks and architectures result fairly inadequate to the task, especially when resource-constrained devices are involved. This work proposes symbolic computation as an effective solution to program resource constrained CPS devices with code maintaining strict ties to high-level specific…
DC4CD
2017
In this article, we present Distributed Computing for Constrained Devices (DC4CD), a novel software architecture that supports symbolic distributed computing on wireless sensor networks. DC4CD integrates the functionalities of a high-level symbolic interpreter, a compiler, and an operating system, and includes networking abstractions to exchange high-level symbolic code among peer devices. Contrarily to other architectures proposed in the literature, DC4CD allows for changes at runtime, even on deployed nodes of both application and system code. Experimental results show that DC4CD is more efficient in terms of memory usage than existing architectures, with which it also compares well in te…
Halaesa Arconidea (Tusa, Messina). Primi risultati dagli scavi delle fortificazioni, settore nord-est.
2023
This report describes the activities and results of two years of archaeological excavations carried out by the University of Palermo at the site of Halaesa, in northern Sicily. The excavations revealed the structure of the ancient city walls (maybe built in two different phases, during the Late Hellenistic/Early Roman peri-od) and the presence of a tank close to the wall, connected to the defense sistem.
