Geovisualizing the sail-to-steam transition through vessel movement data

2017

International audience; Technological transitions in the maritime and port industries go along with increased transport and economic efficiency, resulting in faster movements and longer travelled distances. Yet, such transformations may also enhance disparities between winners and loosers, should they be ports or shipping companies. This research focuses on the particular case of the transition from sail to steam over the period 1890-1925, which witnesses the rapid replacement of sailing vessels, the latter concentrating 65% of the world fleet in 1890 but only 3.5% in 1925. It applies a variety of measures to compare how these two layers overlap in the network (at links and ports) and what …

iHERITAGE Project : AR/VR for the enhancement and accessibility of the norman architecture of the Unesco site of Palermo

2023

In the context of conservation and dissemination of cultural heritage, noninvasive technologies for the generation of digital models have produced exponential growth in the quality of the data acquired. The digital contents processed allow the use of architectural contexts that no longer exist or sites that are di cult to access, thanks to the visualisation of high-resolution and immersive products. However, the process from acquisition to visualisation requires optimisation strategies and specific operational choices, depending on the design goals. The study describes some results of a broader research within the iHERITAGE Project funded by the ENI CBC MED Program 2014-2020, critically des…

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…

„Die Photographie als Hülfsmittel mikroskopischer Forschung”? Joseph von Gerlach (1820-1896) und die frühen anatomischen Mikrophotographen

2005

The Erlangen anatomist Joseph von Gerlach was one of the first medical researchers who used microphotography for their scientific aims in basic tissue research. Already in 1863, Gerlach published a famous handbook on the methodology of the microphotographic technique, entitled Die Photographie als Hulfsmittel mikroskopischer Forschung. Here, he discussed the technological, practical and epistemological standards and constraints of the newly introduced visualisation technique of scientific photography. The efforts and setbacks of Gerlachs' innovative approaches shall be characterised in the present paper. Furthermore, some of the most important arguments put forward by some of his peers are …

Query expansion and semantic visualization in information system cooperations : methods and tools for information retrieval

2010

This thesis presents approaches and tools for information retrieval. Our work is part of a cooperation system based on ontologies called OWSCIS (Ontology and Web Service based Cooperation of Information Sources). We treat the problem of information retrieval by providing an enrichment method called QUEXME (QUery EXpansion MEthod) of queries based on analysis of user behavior and using the concept importance notion with regards to query. We also discussed the problem of visualization in the OWSCIS system offering a architecture of service visualization. It is composed of three modules: the request, enrichment and results. The approaches proposed in this thesis have been prototyped and the te…

A diversity of patterns: 10-year trajectories of men and women diagnosed with psychosis for the first time. A time-geographic approach

2020

People with severe mental illness face a different interventional landscape compared to some decades ago, when mental hospitals were dominant, in Sweden as well as in the rest of the Western world. The aim of the research reported in this article was to follow men and women diagnosed with psychosis for the first time over a 10-year period, and to explore what interventions they experienced. The interventions, here defined as "spheres", were either community-based or institutional. A third sphere represents no interventions. Based on data from registers and using a time-geographic approach, the individuals were visualised as 10-year trajectories where their transitions between the different …

L'utilisation des reliefs naturels dans l'art gravé et sculpté pariétal du paléolithique supérieur français

2005

Pendant toute la durée du Paléolithique supérieur, en Espagne et en France principalement, les artistes ont réalisé des figurations en utilisant les reliefs naturels et la morphologie des parois de grottes ou d'abris-sous-roche. Ce phénomène artistique, qui a toujours préoccupé les préhistoriens, a suscité les interrogations et les interprétations les plus diverses de la fin du XIXe siècle jusqu'à présent : origine de l'art, préoccupations magico-religieuses, organisation spatiale et sanctuarisation de l'espace souterrain, structures pariétales, chamanisme, techno-cultures, etc. Pendant longtemps, ce que les formes rocheuses pouvaient avoir d'évocateur a été considéré comme la raison d'être…
