City Planning Experimentation: the Civitanova Marche Case Study
No full textQuattro parole chiave per interpretare la città contemporanea e per procurare interessi tematici chiari negli scenari di trasformazione urbana - interferenza, flussi, temporaneità, connettività; quattro laboratori disciplinari dell’architettura a confronto tra loro, ognuno con i rispettivi sviluppi progettuali nei processi di rigenerazione e le opportune scale di approfondimento - progettazione architettonica e urbana, tecnologia, urbanistica; una sola città come caso studio - Civitanova Marche: questi sono gli elementi e i componenti principali, che hanno definito la recente esperienza dei laboratori finali delle lauree triennali nella Scuola di Architettura e Design di Ascoli Piceno, Università di Camerino.
L’articolo espone la sfida multidisciplinare condotta dai quattro gruppi di ricerca, le metodologie assunte per comprendere e interpretare la città contemporanea, i risultati progettuali e spaziali sperimentati, gli esiti e il dibattito scientifico condiviso anche con l’amministrazione comunale aperta al dialogo e alla progettualità dell’architettura. Nello specifico il gruppo di docenti e ricercatori afferenti all’ambito disciplinare della Tecnologia dell’Architettura ha assunto la temporaneità come paradigma generatore non di soluzioni determinate ed univoche ma mutevoli ed indefinite.Four keywords to interpret the contemporary city and generate clear thematic interest in urban transformation scenarios – Interference, flows, temporariness, connectivity; a comparison of four disciplinary architectural workshops, each with its own respective approach to the planning of redevelopment processes and suitable levels of analysis – architectural and urban planning, technology, city planning. A single city as a case study – Civitanova Marche: these are the main elements and components defining the recent final graduation workshop experience at the Scuola di Architettura e Design di Ascoli Piceno, Università di Camerino.
The article describes the multidisciplinary challenge faced by the four study groups, the methods adopted to understand and interpret the contemporary city, the experimented planning results and spaces, the outcomes and scientific debate, also shared with the municipal administration proving open to dialogue and architectural planning. Specifically, the Architectural Technology study group assumed temporariness as a paradigm, which rather than developing fixed and univocal solutions developed evolving and indefinite ones
New modularity-based approach to segmentation of water distribution networks
No full textComplex and/or large size water distribution networks (WDNs) require the division of the hydraulic system into modules in order to simplify the analysis and the management tasks. In the modern science of networks, the modularity index has been proposed in order to detect communities, i.e., groups/clusters of nodes characterized by stronger inter-connections. The modularity index is a measure of the strength of the network division into communities and it is maximized in order to identify them. Therefore, the division into modules of WDNs, also named segmentation, could be performed by using the modularity index as metric in order to identify cluster of nodes. Nevertheless, modularity index needs to be revised considering the specificity of the hydraulic systems, which are infrastructure networks. In fact, the division into modules for infrastructure networks, although it can be based on the identification of clusters of nodes, is not aimed at investigating network features. Differently, the aim is the practical issue of simplifying system analysis, planning and management; therefore, the division is constrained by the technical needs. Accordingly, in the present work the classic modularity index is firstly presented. Successively, it is tailored and modified for WDNs. Furthermore, a multi-objective strategy for optimal segmentation is presented and discussed also using a real test network. The optimization framework is based on the maximization of the WDN-oriented modularity-based index versus the minimization of the cost of newly installed devices in order to obtain network segments. Those are a set of optimal divisions into modules of the hydraulic system which are the basis for an integrated, dynamical planning
A novel infrastructure modularity index for the segmentation of water dis-tribution networks
Full text linkThe search for suitable segmentations is a challenging and urgent issue for the analysis, planning
and management of complex water distribution networks (WDNs). In fact, complex and large size hydraulic systems require the division into modules in order to simplify the analysis and the management tasks. In the complex network theory, modularity index has been proposed as a measure of the strength of the network division into modules and its maximization is used in order to identify community of nodes
(i.e., modules) which are characterized by strong interconnections. Nevertheless, modularity index needs to be revised considering the specificity of the hydraulic systems as infrastructure systems. To this aim, the classic modularity index has been recently modified and tailored for WDNs. Nevertheless, the WDN-oriented
modularity is affected by the resolution limit stemming from classic modularity index. Such a limit hampers
the identification/design of small modules and this is a major drawback for technical tasks requiring a detailed resolution of the network segmentation. In order to get over this problem, we propose a novel infrastructure modularity index that is not affected by the resolution limit of the classic one. The rationale and good features of the proposed index are theoretically demonstrated and discussed using two real
