Charging Electric Vehicles Using Opportunistic Stopovers
2017
The diffusion of electric vehicles asks for efficient energy replenishment, which requires geographical and temporal coordination of shared charging resources. We introduce a novel charging methodology that exploits users’ opportunistic mobility. This paper focuses on vehicle stopovers detecting potential charg- ing opportunities. Our mobility-assisted methodology protects users privacy and permits a hybrid centralized/distributed ap- proach avoiding clashes with other potential users. A preliminary analysis on our charging system, obtained with mobility data from the field, shows that among the available charging stations, some are more relevant and have a key role in serving electric vehi…
The Area Of The Strait Reading Theories And Strategies For A Metropolitan Dimension
2016
Abstract Extending across a peninsular strip going from Gioia Tauro to Melito Porto Salvo on the Calabrian side, and from Milazzo to Giardini Naxos on the Sicilian side, the Strait of Sicily sees theAspromonte massif and the Peloritani mountain range as two facing stage sets of land sketching in the gulf a water piazza of a landscaping room. Described in the proposal by Giuseppe and Alberto Samona, Ludovico Quaroni, Antonio Quistelli, Sergio Musmeci, Paolo D’Orsi Villani and Leonardo Urbani, it outlines, in the county seats of Reggio Calabria and Messina, the prevalence of a Euclidean space, identifiable in the exact metrics given by the recurrence of the measuring step of the blocks drawn …
Into the world of e-waste: mobility among e-scrappers in Nigeria
2017
AbstractIn the management of e-waste, mobility of e-scrappers plays a pivotal role, especially in e-waste acquisition and sales of extracted materials. This research examines the relationship between e-scrappers and the locations of their work by analysing the influence of environmental and social factors on their mobility behaviour in Nigeria. A qualitative analysis of video material collected from 29 male e-scrappers in Nigeria between 2014 and 2015 reveals that e-waste has inherent properties that intermittently mobilise e-scrappers to search for recyclable and valuable electronic trash. Applying the new mobilities paradigm and the new materialism theory, we present that e-scrappers’ mob…
Mobility Patterns and Mode Choice Preferences during the COVID-19 Situation
2022
The empirical research on the COVID-19 epidemic’s consequences suggests a major drop in human mobility and a significant shift in travel patterns across all forms of transportation. We can observe a shift from public transport and an increase in car use, and in some cases also increase of cycling and (less often) walking. Furthermore, it seems that micromobility and, more generally, environmentally friendly and comanaged mobility (including shared services), are gaining ground. In previous research, much attention was paid to the mode choice preferences during lockdown, or early stages of the SARS-CoV-2 situation. The blind spot, and aim of this work, is how long observed changes in mode ch…
A System of Equity Indicators for Educational Systems
2001
International audience; Si l'on admet que l'équité d'un système éducatif d'une part ne se mesure pas seulement à la dimension, certes importante, des inégalités sociales d'accès à l'enseignement supérieur, mais peut mobiliser d'autres objets, d'autres catégories, et d'autres principes de justice ; si l'on admet aussi que l'équité d'un système éducatif ne se mesure pas directement, mais dans la capacité de ce système à corriger un certain nombre d'inégalités initiales, dont l'ampleur peut varier d'un pays à l'autre ; si l'on admet enfin que l'équité d'un système éducatif ne s'appréhende pas seulement par des indicateurs internes, mais aussi par la capacité dudit système à instaurer une socié…
Electrophoretic separation of a class of nucleosomes enriched in HMG 14 and 17 and actively transcribed globin genes.
1980
Monomer nucleosomes from chick erythrocytes can be fractionated according to their electrophoretic mobility in (comparatively) high salt acrylamide gels. We show that the fractionation is based predominantly on differences in charge. The monomer heterogeneity persists even when the nucleosomes are trimmed down to 145 bp with Exo III or when H1 and H5 are removed. The slowest migrating monomers are associated with HMG 14 and 17; however, we do not believe that these proteins are entirely responsible for the altered mobility since the nucleosome heterogeneity persists even after removal of HMG 14 and 17. The DNA associated with the HMG 14 and 17 containing nucleosomes is shown to be enriched …
The environmental benefits of carsharing: The case study of Palermo
2020
Abstract The problems related to traffic emissions are becoming increasingly pressing and serious, especially in big cities where the private car plays the main role in the mobility of people, being excessively used, while walking, cycling and the use of public transport are often seen as secondary options and are hampered by a poorly urban environment. Therefore, solutions must be found to reduce the number of cars circulating in the city and to support the most sustainable modes of transport at the same time, in order to reduce emissions of greenhouse gases and harmful substances. A modal alternative which is of undoubted interest could be represented by carsharing, which is a mode comple…
European Universities: Forthem e la mobilità virtuale

The paper deals with the European Universities program and the various projects funded with the participation of Italian universities. …
Sugar reduction in extruded cereal based products : impact of water content on the structure and molecular dynamics in such material
2019
Low-moisture biopolymer-based systems are commonly encountered in food. Obviously, understanding the physical basis of their quality: e.g texture, or performance over time or as a function of their composition is of primary importance. The objectives of this work were to evaluate how the presence of sucrose and water content affects physico-chemical properties. The physical stability of these materials were monitored through an insight at different molecular scales. Then the relations between the multi-scale studies were investigated. The effect of sucrose (0–20%) and feed water (10 and 15%) on extrusion blends was studied using a twin screw extruder under the same processing settings. The …
How endogenous asymmetries in interregional market access trigger regional divergence
2005
International audience; We investigate how asymmetric trade patterns in differentiated products affect the regional distribution of economic activities. The asymmetry in interregional market access is an endogenous result of price competition and industry location and arises for intermediate values of trade costs. We show that the emergence of one-way trade in differentiated products gives rise to strong agglomeration forces and leads to the absorption of the smaller region's industry by the larger region. The number of spatial equilibria increases once the pattern of trade is endogenously accounted for.
