Hydrologic Performance of an Extensive Green Roof under Intensive Rain Events: Results from a Rain-Chamber Simulation
Full text linkThe water storage capacity of a green roof generates several benefits for the building
conterminous environment. The hydrologic performance is conventionally expressed by the runoff
coefficient, according to international standards and guidelines. The runoff coefficient is a dimensionless
number and defines the water retention performance over a long period. At the scale of
single rain events, characterized by varying intensity and duration, the reaction of the green roof is
scarcely investigated. The purpose of this study is to highlight how an extensive green roof—having
a supposed minimum water performance, compared to an intensive one—responds to real and repetitive
rain events, simulated in a rain chamber with controlled rain and runoff data. The experiment
provides, through cumulative curve graphs, the behavior of the green roof sample during four rainy
days. The simulated rain events are based on a statistical study (summarized in the paper) of 25 years
of rain data for a specific location in North Italy characterized by an average rain/year of 1100 mm.
The results prove the active response of the substrate, although thin and mineral, and quick draining,
in terms of water retention and detention during intense rain events. The study raises questions
about how to better express the water performance of green roofs

No full textBrain Magnetic Resonance Imaging Generation using Generative Adversarial Networks
No full textMagnetic Resonance Imaging (MRI) is nowadays one of the most common medical imaging technology, due to its non-invasive nature and the many kind of supported sequences (modalities), that provide unique insights about a particular disease. However, it is not always possible to acquire all the sequences required, for several reasons such as prohibitive scan times or allergies to contrast agents. To overcome this problem and thanks to the recent improvements in Deep Learning, in the last few years researchers have been studying the application of Generative Adversarial Networks, a promising paradigm in deep learning, to generate the missing modalities. In this work we developed and trained two models of Generative Adversarial Networks, called MI-pix2pix and MI-GAN, to solve the problem of generating missing modalities for brain MRIs. In particular, our approaches are multi-input generative models, as they exploit as input several MRI modalities to generate the missing one. Our results are promising and show that the developed models are able to generate rather realistic and good quality images

Transformation procedures in the typology of tall buildings
No full textA series of interventions aimed at facing the introduction of new requirements can be recognized during the life cycle of every existing building. In order to prevent its natural obsolescence, these interventions (which involve both technological system and physical components) are mainly related to the necessary updating tied to the evolution of environmental conditions, the changes of users’ needs and the advances in technology as well.
The main factors of obsolescence can be identified in the following themes:
- change of environmental conditions
- change of the performances required
- change of technologies
The relevance of each of these factors is assessed by this paper, and some examples are used to support the methodology proposed.
Tall buildings represent a particular building typology, because of their role as a landmark and their economic relevance: that’s why continuous renovations and improvements are necessary.
The main systems of a tall building that might be interested by renovations can be identified in the following hierarchical categories: building envelope, internal partitions, mechanicals. In this list the paper focuses on those parameters specifically meant to improve the sustainability of tall buildings recognizing their relevance as a tool to improve the design process

Green living technologies in sustainable refurbishment strategies
No full textThe aim of this research is to study the limits and the benefits deriving from the application of a
“green surface” in a refurbishment action on existing buildings. Requalification processes are often
related to sustainable issues as energy and water saving: the introduction of plant technologies on
roofs and facades can produce an increase of performance in buildings’ envelopes and positive
effects on indoor comfort. A green shading can have positive impacts on energetic balance of a
building. Furthermore a green roof can be considered a strategic solution for retaining and reusing
rainwater. The methodology used is composed of different steps concerning “green technologies”
analysis and refurbishment strategies as well. Theoretic analyses are compared to some studies
investigating the contribution of plant surfaces in the reduction of thermal impacts on walls and
roofs. In the same time a cost/benefit analysis is led to assess the feasibility of the “green strategy” in
a requalification action. Durability of the different technological solutions adopted is specifically
investigated in order to have a life prediction comparable to the expected lifespan of the renewed
building. Maintenance activity is assessed too. As a result, on the one hand the application of a
“green strategy” doesn’t bring to a critical increasing of costs, on the other hand it implies positive
factors in the energetic balance of the intervention. As it is underlined by the results of the studies the
implementation of the building envelope through plant technologies can be considered, especially in
dense urban areas, a suitable solution to offer a green answer to refurbishment action demand
"Spettrometria a microfluorescenza a raggi X a dispersione di energia (μ-XRF)”, in “Restauro di due codici del XV secolo”
No full textIl quaderno illustra l'intervento di restauro eseguito su due codici del Museo archeologico nazionale di Cividale del Friuli reso possibile grazie alla sottoscrizione di un protocollo d'intesa tra Mibac e la Regione Friuli Venezia Giulia e al coinvolgimento degli atenei di Trieste e Udine.
La pubblicazione dedica ampio spazio alle attività del Centro nel campo dei progetti internazionali, della sperimentazione, delle partnership, dell'editoria e della formazione.
Le descrizioni degli interventi di restauro sono corredate dalla descrizione archeologica dei codici, da esaurienti relazioni sulle indagini scientifiche effettuate e da una consistente documentazione fotografica
