Indicators of rivers geomorphological functionality, application of the EU Water Framework Directive in Sicily (Italy)

2015

Many river systems in Europe suffer from human pressure. For this reason the European Water Framework Directive (WFD; 2000/60/EC) was created for river basin and floods management. In 2010 the Italian Environmental Minister issued the WFD and a protocol for the stream hydromorphological evaluation, analysis, and monitoring was established (IDRAIM). The Morphology Quality Index (MQI) is part of this procedure and defines the deviation of present geomorphic reach situation from reference conditions. It is composed by Indicators of Geomorphological Functionality (IGF), Indicators of Artificiality (IA) and Indicators of Channel Adjustments (ICA). The present work aims at illustrating the calcula…

The role of EPS in fouling and foaming phenomena occurring in an UCT-MBR pilot plant

2012

The aim of this study is to detect a possible relationship between EPS and fouling and EPS and foaming in a University Cape Town (UCT) membrane bioreactor (MBR) pilot plant. The UCT-MBR pilot plant was fed with 40 L/h of real wastewater and monitored for 165 days. Specifically physical/chemical features of influent, permeate and mixed liquor in different sections were analyzed. The fouling phenomenon was studied monitoring the hydraulic resistances of the membrane. The extracellular polymeric substances (EPSs) concentration inside the aerobic tank were also measured. The foaming phenomenon was monitored by performing the Foam Power and Scum Index testes. Results have shown a high correlatio…

BIOLOGICAL STABILITY ANALYSIS OF THE OFMSW MATRIX TREATED IN A COMPOSTING PLANT

2011

Composting, mechanical-biological treatment (MBT), biodrying and biostabilization processes of pre-selected organic fraction from municipal solid wastes (OFMSW) have recently become important in municipal solid waste management. Through these treatment processes the potential impacts of the produced wastes and the volume to treat in the landfill are strongly reduced. However, the residual organic matter contained in the treated fraction may provide negative effects when e.g. the treated OFMSW is used as compost. The biological stability degree of the treated matrix provides usefull informations for the final use of it. Indeed, knowing the degree of biological stability of the compost makes …

Pasquale Culotta. Scritti e progetti

2010

A critical index of selected projects and biographical milestones of the sicilian architect Pasquale Culotta (Cefalù, July 30, 1939 - Lioni, November 9, 2006), graduated in architecture in 1965, ince 1986 he has been Full Professor of Architectural Design and Director of the Department of History and Project in Architecture of the Faculty of Architecture of Palermo since 1986 to 1989 and from 2001 to 2006. From 1989 to 1996 he was Dean of the Faculty of Architecture in Palermo and, since 2000, President of the Board of the Architecture Degree Course in Palermo. In 1987 he was called by the Milan Triennale for the formulation and scientific coordination of projects on " L’architettura della …

Appraising building area’s index numbers using repeat values model. A case study in Paternò (CT)

2013

The knowledge of real estate prices trend over time is requisite to understand and expect dynamics of real estate market, and is useful to construct index numbers of real estate prices, numerical indicators exploitable to understand real estate profitability and land phenomena in different market segments. This work aims at the construction of prices index numbers relevant to building area site in the town of Paternò, in Catania province, and at the corresponding hedonic prices index numbers linked to the main real estate characteristics in the space of a period that goes from 2004 to 2012. The proposed methodology allows to build the index numbers of the building area’s unit prices in the …

Content Based Indexing of Image and Video Databases by Global and Shape Features

1996

Indexing and retrieval methods based on the image content are required to effectively use information from the large repositories of digital images and videos currently available. Both global (colour, texture, motion, etc.) and local (object shape, etc.) features are needed to perform a reliable content based retrieval. We present a method for automatic extraction of global image features, like colour and motion parameters, and their use for data restriction in video database querying. Further retrieval is therefore accomplished, in a restricted set of images, by shape feature (skeleton, local symmetry moments, correlation, etc.) local search. The proposed indexing methodology has been deve…

Green roofs for smart cities: experimental determination of the “fractional vegetation coverage” of six vegetated species

2015

Towards a de-carbonization of European countries, green roofs are becoming popular, due not only to aesthetic reasons but also to energy and environmental issues. Indeed, especially in summer periods, the building cooling demand might be sensibly cut thanks to such passive components often chosen for planning smart cities. To properly model the energy performances of buildings equipped with these components, a particular attention must be paid to radiative exchanges occurring among soil surface, leaves and outdoor surroundings. These thermal exchanges depend on parameters, like the “fractional vegetation coverage” whose literature data do not seem particularly suitable for the simulation ne…

Risk indexes evaluation in view of a new showcase designing of “L’Annunciata” by Antonello da Messina

2018

Museums are often hosted by heritage buildings, where the indoor thermal conditions are usually subjected to a free-floating regime, due to the difficulty of equipping them with HVAC systems that, generally, are highly impacting tools from a visual point of view. These technological tools, in fact, could conflict with the established arrangement of the works of art. This would represent a problem, since the indoor physical conditions of these premises must fall within the ranges of values suitable to ensure the safety of the works of art there exhibited. In addition, the increasing time spent by visitors inside museums (now offering various possibilities of leisure, ranging from the book sh…
