An energy efficiency analysis of single point incremental forming as an approach for sheet metal based component reuse
2020
Producing materials causes about 25% of all anthropogenic CO2 emissions. Metals play a significant role, steel and aluminum account for 24% and 3% of worldwide material related emissions respectively. Fostering resources efficiency strategies in the field of sheet components could lead to a significant environmental impact reduction. Reshaping could be one of the most efficient strategy to foster material reuse and lower the environmental impact due to material production. Specifically, for aluminum recycling, the overall energy efficiency of conventional route is very low and, more importantly, permanent material losses occur during re-melting because of oxidation. The present paper aims a…
European National Road Authorities and Circular Economy: An Insight into Their Approaches
2020
The pavement engineering industry, having realized the significance of the impacts that it imposes on the environment through the production, construction and management of its products and assets, has been driven towards a more sustainable and circular way of operating. This has partly been through asphalt recycling, which is an area that many road authorities have prioritized. However, not all the National Road Authorities (NRAs) and/or sector stakeholders seem to be adequately familiar with the Circular Economy (CE) concept. This paper attempts to assist the transition of NRAs to a more circular way of doing business, by analyzing the current situation of CE within national/regional auth…
URBAN RESILIENCE AND WASTE MANAGEMENT: PROPOSALS OF NEW INFRASTRUCTURES FOR URBAN AREAS AND BUILDINGS
2015
La produzione ingente di rifiuti, quale conseguenza di costumi di vita volti allo spreco, rende vulnerabili i sistemi urbani che possono essere sottoposti, in casi emergenziali, a pressioni eccezionali e incontrollate con situazioni prossime al collasso. Un’opportuna e corretta gestione integrata dei rifiuti contribuisce alla resilienza dei sistemi urbani. Perciò si rendono necessarie la pianificazione e la progettazione di nuovi servizi e l’individuazione/integrazione di spazi e dotazioni tecnologiche per incentivare la popolazione a effettuare la raccolta differenziata in modo corretto e costante. Si presentano gli esiti di uno studio svolto in un piccolo centro siciliano. Partendo dalle …
Trasformazioni urbane tra criticità irrisolte e sfide moderne
2021
Ancora una volta una riflessione sulla città è al centro dell’attenzione di tanti studiosi. Come potrebbe essere diversamente? Oggetto di studio così importante, così mutevole e così determinante per la vita degli esseri umani, la città è un organismo in continua trasformazione: da sempre si discute della sua nascita e della sua evoluzione nei vari periodi storici, ponendo enfasi sull’urbanizzazione, sulla sua crescita e sul suo sviluppo, sulla memoria e sulle tracce di umanità e di cultura che in essa possono scorgersi. Le città sono tutte diverse, ma se prendiamo in considerazione solo una di queste, sarà percepita in modo diverso da ciascuno dei suoi fruitori. Esiste quella ideale, ovver…
Urban and Transit Planning. A Culmination of Selected Research Papers from IEREK Conferences on Urban Planning, Architecture and Green Urbanism, Ital…
2020
A volume of five parts, this book is a culmination of selected research papers from the second version of the international conferences on Urban Planning & Architectural Design for sustainable Development (UPADSD) and Urban Transit and Sustainable Networks (UTSN) of 2017 in Palermo and the first of the Resilient and Responsible Architecture and Urbanism Conference (RRAU) of 2018 in the Netherlands. This book, not only discusses environmental challenges of the world today, but also informs the reader of the new technologies, tools, and approaches used today for successful planning and development as well as new and upcoming ones. Chapters of this book provide in-depth debates on fields o…
New Insights of Profile Oriented Marketing and Adaption Management for a Future-Oriented City Development
2017
The world is changing fast, and cities are facing complex transitions in economic, social and environmental areas. Therefore, the design of city systems will play an essential role in shaping a sustainable, innovative and livable future. Adaptive urban profiling was recently presented as a useful tool for municipals to enhance sustainable city development. It builds upon profile oriented marketing while including elements of adaption management. Thus, city managers can increase their cities attractiveness by providing it with a clear profile that is recognized around the world on the one hand, while flexibly adapting to change if necessary. Only an integrated approach that puts people first…
The urban revitalization of the coastal tourist destinations: An alternative for the Valencian Mediterranean tourist municipalities
2021
espanolLos municipios del litoral mediterraneo valenciano aumentaron sensiblemente su superficie construida por la irrupcion de la actividad turistica a mediados del siglo XX. A pesar de las ventajas iniciales, los problemas surgidos sobre el espacio urbano, por la naturaleza del modelo de desarrollo turistico utilizado, los dirigen hacia una perdida progresiva de su atractivo turistico. Ante esta circunstancia, se hace necesario intervenir sobre el espacio urbano, no solo para renovar el destino turistico sino tambien para corregir los problemas urbanos generados durante las ultimas decadas en unos municipios que supeditaron sus decisiones exclusivamente a las necesidades turisticas. Una o…
Rethinking Civil Society in Development: Scales and Situated Hegemonies
2016
Ethnic residential segregation is often explained with the claim that ‘immigrants don’t want to integrate—they prefer to stick together with co-ethnics’. By contrast, mixed neighbourhoods are seen as crucial for achieving social cohesion. In line with spatial assimilation theory there is a normative assumption that people interact with those living nearby. From interviews on neighbourhood qualities and locations valued by Oslo residents of Turkish, Somali and Polish backgrounds, we raise questions about the validity of two assumptions: that most immigrants want to live in the same neighbourhoods as co-ethnics; and that they want to live close to co-ethnics because they do not want to integr…
Kulturen des Reparierens
2018
Reparieren und Instandhalten sind ökonomisch wie kulturell zentrale Praktiken im »Leben« technischer Dinge und Infrastrukturen. Der Band rückt diese bislang wenig untersuchten Tätigkeiten in den Vordergrund und fragt nach den Wissensformen der unterschiedlichen Kulturen des Reparierens. Die Expertisen und politischen Ambitionen menschlicher Akteure finden dabei ebenso Berücksichtigung wie die Eigendynamik der Dinge. Die Beiträge untersuchen Praktiken wie die Uhr- oder Computerreparatur sowie Räume wie die Wohnung und das Krankenhaus, das Repair Café und die Stadt des Globalen Südens. Nicht zuletzt geht es um die Frage, inwiefern Reparieren und reparaturfreundliches Design zu mehr Nachhaltig…
Stochastic models for wind speed forecasting
2011
Abstract This paper is concerned with the problem of developing a general class of stochastic models for hourly average wind speed time series. The proposed approach has been applied to the time series recorded during 4 years in two sites of Sicily, a region of Italy, and it has attained valuable results in terms both of modelling and forecasting. Moreover, the 24 h predictions obtained employing only 1-month time series are quite similar to those provided by a feed-forward artificial neural network trained on 2 years data.
