Reti sismiche urbane per monitoraggio sismico monitoraggio strutturale ed allerta precoce
2021
In questa tesi, viene effettuato un analisi preliminare in cui si mette in evidenza come l'italia sia un paese a rischio sismico, poichè possiede molti centri storici con strutture non progettate per eventi sismici di media entità. Si è prestato molta attenzione su quante vite umane vengono salvate dopo un terremoto catastrofico. L'analisi fa emergere come, è importante essere tempestivi nell'estrarre le persone rimaste sotto le macerie, poichè la percentuale di persone estratte vive si mantiene alta solo entro le 48 ore dall'evento. Dopo 96 ore questa percentule si attesta a 0. In eventi passati spesso i soccorsi sono arrivati con giorni di ritardo nelle zone più devastate. L'obbiettivo ch…
The airport as edge city : the case of Paris' Charles de Gaulle airport
2005
International audience; Most of the recent research about airports has considered them in their role as points within airline networks,and the focus has been generally on hub airports. But airports are also places offering many similarities with cities, particularly with edge cities. They are places of human diversity and job centers for surrounding areas. Traffic jams are common on ground facilities as they are on taxiways, runways and airways. Often divided in specialized districts, such as cargo warehousing, hotel rows, rental car parking lots or office clusters, they are also urban organisms exerting strong demands on the local environment. In the post 9-11era, their importance for econ…
Emerging Trends, Issues, and Challenges in Big Data and Its Implementation toward Future Smart Cities
2017
The articles in this special section focus on Big Data as it impacts future smart cities. The world is experiencing a period of extreme urbanization. Moreover, this process will continue, and the global urban population is expected to double by 2050. Smart city has been proposed to improve the efficiency of services and meet residents’ needs for better quality of life. Essentially, smart city integrates the Internet of Things and emerging communication technologies such as fifth generation (5G) solutions to manage the citys’ assets, including transportation systems, hospitals, water supply networks, waste management, and so on. Therefore, smart city is driving innovation and new technologie…
Intra-urban residential differentiation in the post-Soviet city: the case of Riga, Latvia
2014
Cities in many Central and Eastern European (CEE) countries have transformed rapidly since the political and socio-economic restructuring started in the early 1990s. Economi reforms, growing income inequalities, changes in housing system and selective residential mobility are resulting in increasing socio-spatial differentiation among urban neighbourhoods also in Riga. In addition, litt le is known about the ethnic dimension of intra-urban residential differentiation, despite the existence of sizeable minority populations. The focus on ethnicity is important, since Riga is the only capital city in the Baltic States where the ethnic majority is outnumbered by the non-Latvian minority. This p…
The Fluid City Experience: An Update
2016
This chapter describes the actual status of thirteen European cities that become fluid cities through their strategies for urban regeneration. These cities are divided into three groups: the large port-cities, the medium rank “city-port” cities, the riverfront cities. For every city, we define the status of urban environment and population, the trend for port and airport traffic and the strategies for urban regeneration.
Efficient Power Allocation for Multi-Cell Uplink NOMA Network
2019
Digital technologies are rapidly shaping the modern concepts of urbanization. It is a key element of developing practical smart cities of the future. In fact, they are the catalyst for the increasing networking of all areas of life in a smart city. Recent development in the domain of communication technologies has opened new avenues to realize the concept of smart cities. One of such communication technology is non-orthogonal multiple access (NOMA) for future cellular communications. This article, therefore, focuses on the interference management of uplink cellular NOMA systems. Specifically, we propose a power optimization technique for NOMA to improve the sum-rate in a multi-cell environm…
L’ampliamento come occasione di recupero della memoria e dell’identità
2012
We present the enlargement plan of an isolated cemetery in a small town of the west Sicily as it exemplifies some way to carry out the design for an “addition”. The enlargement faces a still readable and characteristic nineteenth-century building. Even introducing unavoidable innovative characteristics, the architecture we designed tries to resolve the difficult relationship between the new portion and the old cemetery, bell shaped, in steep slope above the town. The recovery of this place for collective memory, once realized as a closed enclosure, is realized by the mediation of a space which seeks to maintain, recover and reinforce the identity of places altered in the last years by uncon…
Prese urbane. Studi di enunciazioni cittadine
2017
Distinguished and diverse theorists such as Benveniste, Barthes, De Certeau and Lotman have each approached the city in different ways. But while several key differences exist between them, their points of view intertwine around the concept of urban enunciation and intersect at differing points. In this study, the positions of these authors will be presented, compared and elaborated upon and the categories of linguistic enunciation of urban space will be set out, drawing from a vision of translation between languages that frequently leads, as is so often the case in Semiotics, to productive analytical models. The linguistic signs of the city will also be illustrated by examples of "short fo…
El sistema escolar en la ciudad de Valencia en el siglo XV
2019
En la València de finals de l’Edat Mitjana existí una reduïda inserció de l’ensenyament de les lletres en el món de l’aprenentatge domèstic. Per a les famílies benestants, l’escola de gramàtica era la prolongació de l’ensenyament domèstic allí on no arribava la competència paterna. L’església era l’única institució que, fins finals del segle XIV, comptava amb els mitjans i personal necessari per a mantenir escoles. A partir de 1373 la intervenció municipal posà fi al monopoli eclesiàstic. Durant el segle XV coexistiren les escoles subvencionades per l’esglèsia i pel municipi, juntament amb altres d’independents.
Changes in Family Income around the Time of Birth of Children in Germany between 1985 and 2004
2010
Während der Verlauf und die Ursachen des Geburtenverhaltens intensiv erforscht wurden, sind die finanziellen Folgen einer Geburt empirisch kaum beachtet worden. Daher werden hier kurzfristige Wohlstandsveränderungen von Familien (hinsichtlich verfügbarem Haushaltseinkommen und Äquivalenzeinkommen) rund um die Geburt eines Kindes in längsschnittlicher Perspektive analysiert und auf ihre Ursachen untersucht. Zu diesem Zweck wurden die Daten des Sozio-oekonomischen Panels (1984-2005) mittels Fixed-Effekt-Panelregressionsmodellen analysiert. Als Ergebnis kann festgehalten werden, dass die finanziellen Folgen einer Geburt in den letzten Jahren deutlich gewachsen sind und vor allem das erste Kind…
