LOFAR measures the hotspot advance speed of the high-redshift blazar S5 0836+710

2019

Our goal is to study the termination of an AGN jet in the young universe and to deduce physical parameters of the jet and the intergalactic medium. We use LOFAR to image the long-wavelength radio emission of the high-redshift blazar S5 0836+710 on arcsecond scales between 120 MHz and 160 MHz. The LOFAR image shows a compact unresolved core and a resolved emission region about 1.5 arcsec to the southwest of the radio core. This structure is in general agreement with previous higher-frequency radio observations with MERLIN and the VLA. The southern component shows a moderately steep spectrum with a spectral index of about $\gtrsim -1$ while the spectral index of the core is flat to slightly i…

Mapping the Distortions in Time and Space: The French Railway Network 1830–1930

2013

International audience; Accessibility is frequently used in transportation planning to measure the efficiency of new infrastructure in terms of travel time and population served. In this article, the authors apply accessibility concepts based on the geo-historical angle. The aim of this study is to investigate the relationships between population dynamics and the railway expansion from 1830 to 1930. Their approach considers a local scale composed of some 36,000 French communes for the demographic data and more than 28,000 kilometers for the railway network. The methodological framework of this database is based on historical geographic information systems completed by anamorphosis analysis.…

“A Perfect Heroine in Foreign Travel.” Female Mobile Identities and Southern Italy in the 19th Century Non-feminist Periodical Press

2016

This essay focuses on the inteaction between the publication of female travel writing abouth the South Of Italy in non -feminist 19th century British periodicaldìs and the circulation of a transgressive model of femininity centred on the concepts of mobility, vitality and visibility. the choice of Southern Italy, and anti-tourist destination that since the era of the Grand Tour had been considered dangerous for men, let alone for women, magnifies female heroic attitudes and contaminates female conventional domestic purity enhancing the concept of an unfixed female identity. The publications of a travelogue, a mostly non fictional genre, on an innovative and reactive medium, was a manifest a…

Modes de représentation des trajectoires quotidiennes des habitants

2007

Representing the daily trajectories of individuals Current research on inhabitants' daily mobilities has confirmed that individual mobility strategies are based on activity programmes. In France, the Household Travel Survey (HTS) is one of the principal sources of information about individual travel behaviour. Despite some drawbacks, they are rich sources of spatio-temporal data, as well as providing information on individual and household characteristics. However, for daily mobilities to be analysed, the raw data need to be reorganized. This study is based on the Grenoble-area Household Travel Survey, carried out in 2002. We propose to explore the HTS data through examples of individual mo…

Testing a distributed approach for modelling sediment delivery

1998

Abstract Both the theoretical basis of a distributed approach to sediment delivery and its agreement with basin sediment yield measurements are tested. At first, by using morphological data of five Apulian and four Calabrian basins, the applicability of a theoretically-based relationship for evaluating the sediment delivery ratio of each morphological unit SDR h, into which a basin is divided, is verified. Using the morphological data of the nine investigated basins, the sediment delivery relationship, i.e. the relationship of the basin sediment delivery ratio SDR Wand SDR h, is tested. The analysis showed that the relationships, proposed by Ferro (1997), establishing the dependence of the …

Mining travel patterns from mobile ticket applications

2014

Masteroppgave i Informasjons- og kommunikasjonsteknologi IKT590 Universitetet i Agder 2014 Customers’ travel patterns are highly interesting for transportation companies due tothe insight it gives over the use for their services. Logs of the customers’ location datais an important source for such companies. However, such data is not collected and isprivately owned by the individual customers. To find the customers’ travel patterns,their location data requires to match a coded map of transportation network.This paper introduces a novel solution that automatically collects location and timedata from the customers without the need for the customers to actively submit thedata. This paper presen…

CEFLES2: The remote sensing component to quantify photosynthetic efficiency from the leaf to the region by measuring sun-induced fluorescence in the …

2009

The CEFLES2 campaign during the Carbo Europe Regional Experiment Strategy was designed to provide simultaneous airborne measurements of solar induced fluorescence and CO<sub>2</sub> fluxes. It was combined with extensive ground-based quantification of leaf- and canopy-level processes in support of ESA's Candidate Earth Explorer Mission of the "Fluorescence Explorer" (FLEX). The aim of this campaign was to test if fluorescence signal detected from an airborne platform can be used to improve estimates of plant mediated exchange on the mesoscale. Canopy fluorescence was quantified from four airborne platforms using a combination of novel sensors: (i) the prototype ai…

iViaggio: the app for safe traveling.

2019

he number of people travelling internationally increases year after year, mainly due to the more and more affordable cost of travelling and to the evergreater ease of transportation. Nowadays, any destination can be reached within 24 hours by plane, and the improvement of economic conditions facilitates both business and leisure travelling, as a matter of fact, according to data from the World Tourism Organization, the number of international trips is expected to increase by 3% to 4% per year.1 However, international travelling poses various health risks depending on travelers’ health conditions and the type of trip undertaken. Indeed, travelers may experience sudden changes in altitude, hu…
