Essays on social capital and space
2014
The idea of specific values and beliefs as, ceteris paribus, the main explanatory of growth differentials, has recently received lot of attention by social scientists. The focus is in particular to specific shared values and beliefs, constituting a social "stock" of good values fostering growth and cooperation, thus the name, social capital. Unfortunately, social capital is an elastic concept. Moreover, to the extent that social interactions type and strength matter, social capital clearly requires attention for the role of space. Thus, this thesis attempts to clarify some of the issues related to social capital and space. In the first chapter we outline the main questions of this thesis, i…
Transformative technologies, spatial changes : essays on mobile phones and the Internet
2009
Sakari Taipale tarkastelee väitöskirjassaan sitä, kuinka matkapuhelimen ja internetin käyttö vaikuttaa sosiaalisten tilojen muodostumiseen.Uudet informaatio- ja kommunikaatioteknologiat ovat monipuolistaneet sosiaalisen vuorovaikutuksen muotoja. Matkapuhelimen ja internetin avulla sosiaalisia tiloja, erilaisia toimijoiden yhteenliittymiä, voidaan luoda tietoverkoissa ilman toisten ihmisten fyysistä läsnäoloa. Tämän seurauksena sosiaalisen tilan kahden keskeisen osatekijän, rajojen ja tarkoituksen, välinen suhde on muuttunut. Rajat näyttävät menettäneen suhteellista merkitystään sosiaalisen tilan koossapysyvyyden kannalta, kun taas tilan tarkoituksen merkitys on vahvistunut.- Verkkoympäristö…
Video projection mapping e arti performative. Una nuova macchina scenotecnica della visione per generare nuovi spazi aumentati
L’oggetto principale della dissertazione è il video projection mapping, un’applicazione di realtà aumentata che utilizza le tecniche di videoproiezione digitale non su tradizionali schermi di proiezione ma sulla realtà stessa, sugli oggetti fisici, ai quali si adatta e si lega in maniera inestricabile, ibridando il livello fisico-reale e il livello digitale. Al contrario di come spesso è stato considerato, il video projection mapping non è solo un gadget tecnologico dei nostri tempi; quando si ibrida con altri media, come le arti performative, diviene linguaggio metaforico, oltrepassando il suo livello tecnologico per produrre significati, per mediare idee. Considerando il suo uso nello spe…
La viralité dans l’espace public numérique
2018
Depuis 2007 et la campagne électorale de Ségolène Royal, « Désir d’avenir », les communicants, les militants et les activistes utilisent la potentialité des dispositifs sociotechniques au service de leur candidat et de la propagation de leurs idées. Les réseaux sociaux ont profondément changé la stratégie de communication des équipes de campagne qui ont préempté l’espace numérique en multipliant leur présence social (Facebook, Twitter, Instagram, etc.). Souvent composées de digital natives et d’individus maitrisant les codes et les rites en vigueur sur ces dispositifs, les équipes intègrent la force du canal de communication afin de renouveler la relation et la communication entre le politi…
Applying Axial Symmetries to Historical Silk Fabrics: SILKNOW’s Virtual Loom
2020
Symmetry is part of textile art in patterns and motifs that decorate fabrics, which are made by the interlacement of warp and wefts. Moreover, the 3D representation of fabrics have already been studied by some authors

Regularity for nonlinear stochastic games
2015
We establish regularity for functions satisfying a dynamic programming equation, which may arise for example from stochastic games or discretization schemes. Our results can also be utilized in obtaining regularity and existence results for the corresponding partial differential equations. peerReviewed
Proposition méthodologique pour la visualisation et l'exploration des mobilités géographiques
2016
Daily mobility data are multidimensional and desaggregated, what make them hard to manipulate and to analyze. Although methods of representation and analyze have been proposed, none of them seem to be able to efficiently bring out knowledge from data. We propose to combinate this solutions and a methodology of innovative reaggregation to visualize and explore mobility data.
A model of degassing for Stromboli volcano
2010
International audience; A better understanding of degassing processes at open-vent basaltic volcanoes requires collection of new datasets of H2O–CO2–SO2 volcanic gas plume compositions, which acquisition has long been hampered by technical limitations. Here, we use the MultiGAS technique to provide the best-documented record of gas plume discharges from Stromboli volcano to date. We show that Stromboli's gases are dominated by H2O (48–98 mol%; mean, 80%), and by CO2 (2–50 mol%; mean, 17%) and SO2 (0.2–14 mol%; mean, 3%). The significant temporal variability in our dataset reflects the dynamic nature of degassing process during Strombolian activity; which we explore by interpreting our gas m…
Decoupled control scheme of grid-connected split-source inverters
2017
Grid-connected power conversion systems for renewable energy sources must fulfill several requirements, e.g., the high efficiency, the reduced cost and complexity, and, quite often, the boost capabilities that is usually achieved using a front-end dc–dc boost converter before the inversion stage, leading to a two-stage architecture. Meanwhile, single-stage power conversion systems, which perform the boosting operation within the inversion one, offer some potential advantages, in terms of reducing the complexity and the volume of the whole system. Among several proposed options, the split-source inverter (SSI) has been recently proposed by Abdelhakim et al. as an alternative option with some…
