Evaluation of the Use of a City Center through the Use of Bluetooth Sensors Network
2019
In order to achieve the objectives of Smart Cities, public administrations need to take measures to regulate mobility, which undoubtedly requires a high level of information and sensorization. Until the implementation of the connected vehicle takes place, it is still necessary to install sensors to obtain information about mobility. Bluetooth sensors are becoming a useful tool due to the low cost of equipment and installation. The use of Bluetooth sensors in cities, with short distances between sensors, makes it necessary to propose new classification algorithms that allow the trips of pedestrians and vehicles to be differentiated. This article presents the study carried out in the city of …
A Comparison of Advanced Regression Algorithms for Quantifying Urban Land Cover
2014
Quantitative methods for mapping sub-pixel land cover fractions are gaining increasing attention, particularly with regard to upcoming hyperspectral satellite missions. We evaluated five advanced regression algorithms combined with synthetically mixed training data for quantifying urban land cover from HyMap data at 3.6 and 9 m spatial resolution. Methods included support vector regression (SVR), kernel ridge regression (KRR), artificial neural networks (NN), random forest regression (RFR) and partial least squares regression (PLSR). Our experiments demonstrate that both kernel methods SVR and KRR yield high accuracies for mapping complex urban surface types, i.e., rooftops, pavements, gras…
Smart city. Four approaches to the concept of understanding
2020
The paper analyzes the rhetoric of the smart city (SC) concept in order to recognize, categorize, and describe different perspectives of understanding the notion. Four approaches to the SC concept were isolated: three affirmative, and one rejecting. The approaches present a different understanding of the SC and indicate different elements creating urban ‘smartness.’ Despite differences, there is one common goal in every affirmative approach: to improve the quality of urban life. It is achieved through activities covering five dimensions distinguished within affirmative approaches. Together they can serve, i.e.,as a framework for SC case study analyses.
From fractal urban pattern analysis to fractal urban planning concepts
2014
International audience; Fractal geometry can be used to develop a multiscale approach toinvestigate the spatial organization of urban fabrics. First, the concepts behindfractal reference models are introduced so as to provide a better understandingof the results obtained from empirical analyses of urban patterns. Then, differentmethods for conducting fractal analyses are presented and the results obtained forurban patterns are discussed. It turns out that, despite their irregular appearance,urban patterns are often organized by an inherent fractal order principle, at leastacross a certain range of scales. More detailed analysis of the findings reveals linksbetween these fractal properties a…
The Integration and Sharing of Resources for a New Quality of Living
2014
In questo capitolo, il tema della condivisione è trattato anche dal punto di vista giuridico attraverso una discussione caratterizzante il dibattito rilevante. Sono quindi approfondite le questioni inerenti le funzioni e la forma urbana. L’IT infatti può interagire con problemi operativi della città e con l’uso delle risorse ambientali (energia, suolo, acqua…), parametro indicativo su cui devono essere sviluppate le trasformazioni urbane. Come condividere gli spazi e le funzioni urbane costituisce la nuova frontiera nel campo dell’innovazione urbana. In this chapter, the issues of sharing of information and of information technologies use are dealt with from the juridical point of view, thr…
Universal design as resilient urban space plan strategy. New scenarios for environmental resources’ sustainable management
2021
Nowadays, urban framework, stressed by the growing anthropic pressure and its constantly evolving use requests is split by uneven structures, contexts, users and patchy needs, which come out to be inefficient and ineffective in access and management. This fact is directly connected both with morph-functional structure of urban texture and its continuous changing trends. The most important consequences of this situation are some negative effects that produce entropy, mistaken anthropic space uses, ecological networks decrease and most of all a substantial urban life quality reduction connected with mobility problems and non-resilient spaces' use at the different plan scales. These elements m…
Unfolding the relationship between resilient firms and the region
2017
ABSTRACTThis research explores organizational resilience in four manufacturing firms in four different regions of Norway. While regional resilience has gained attention in research, there have been few studies with a micro-level focus, investigating firms and their distinctive features of resilience. We chose a qualitative multiple-case study approach and employed a critical incident technique to study resilience in selected firms that had experienced external shocks and shifts in regard to changing markets, globalization and advances in technology. Each, however, had managed to continually develop resilience capacity over time. Our framework considered three dimensions of organizational re…
Le community culturali al tempo della crisi. Nuovi spazi e nuove narrazioni
2022
Il saggio riflette sul ruolo delle comunità culturali all'interno delle narrazioni contemporanee a partire dalla crisi pandemica che ha attraversato il pianeta nel 2020. Attraverso l'individuazione di buone pratiche informali ed istituzionali l'autore assegna ad alcuni protagonisti dell'arte contemporanea e del teatro il ruolo di esperienze innovative nell'ambito della cultura.
The Hydraulic space of the Conca d'Oro of Palermo as a paradigm of the Mediterranean water sensitive city.
2016
The orchards TAL on Palermo periurban countryside follows the Arab conception of hydraulic space. The concept of Hydraulic space combines several technologies to achieve the best use of water resources by differentiating agricultural productions in time and space and by connecting different functions (hydraulic, climatic and aesthetic) in a homogeneous system. This conception of space extends to the whole Conca d’Oro across the countryside to the heart of the historical town to the intimate domestic space in the end. During the Norman age the Zisa source used to refresh and embellish the interior of the castle before water slides towards the gardens; on the surface of Fawara-Maredolce lake …
Local Interactions and the Global City Metropolization in Warsaw
2002
A number of the world's large cities are taking on increasing economic importance in the international arenas because they concentrate high-order activities This metropolization process is a result of the changes occurring in the emerging post-industrial economy, i.e. the rise of services and information. It is based on the combination of proximity interactions and global interactions and it is characterized both by a specific internal spatial pattern and by a large outside area of influence. Since the transition period, services, and particularly high-order services, have grown more rapidly in Poland than in EU countries, as if a catching-up process has been underway. A large part of these…
