This paper examines how and to what extent Luxembourg society was “exposed” to visual representations of the prospering steel industries and labour and working-class culture(s) from the 1880s until the 1920s – a period of massive industrialisation – and how it thus gradually “learned to labour”. Indeed, modern visual media were seen as ideal catalysts for the circulation, transmission and production of meaning, since they were considered to be appealing, objective, direct and capable of inspiring the imagination. The paper takes the reader through various mundane moments and events of industrial enculturation (annual funfair, slide lecture, vocational school, etc.) and engages with different “technologies of display” (photographs, fair albums, postcards, scale models, etc.) that subtly calibrated, conveyed and inculcated the new industrial reality “through the eye” and, in the process, (re)produced national identifications. By zooming in on these different “visual encounters” with industry and by bringing these isolated encounters together in one story, the paper (re)constructs a “learning route” – one among many possible pathways through this huge dynamic field of learning resources (or, “cultural ecology”) – and thus suggests how (informal) “cultural learning” might have taken place at the time. While accompanying us on this journey, the reader gains insights into how this field of resources evolved and how the industrial present was (re)framed, visually performed and (re)configured over time.

Synchronisation of Model Visualisation and Code Generation Based on Model Transformation

The development, maintenance and documentation of complex systems is commonly supported by model-driven approaches where system properties are captured by visual models at different layers of abstraction and from different perspectives as proposed by the Object Management Group (OMG) and its model-driven architecture. Generally, a model is a concrete view on the system from a specific perspective in a particular domain. We focus on visual models in the form of diagrams and whose syntax is defined by domain-specific modelling languages (DSLs). Different models may represent different views on a system, i.e., they may be linked to each other by sharing a common set of information. Therefore, models that are expressed in one DSL may be transformed to interlinked models in other DSLs and furthermore, model updates may be synchronised between different domains. Concretely, this thesis presents the transformation and synchronisation of source code (abstract syntax trees, ASTs) written in the Satellite-Procedure & Execution Language (SPELL) to flow charts (code visualisation) and vice versa (code generation) as the result of an industrial case study. The transformation and synchronisation are performed based on existing approaches for model transformations and synchronisations between two domains in the theoretic framework of graph transformation where models are represented by graphs. Furthermore, extensions to existing approaches are presented for treating non-determinism in concurrent model synchronisations. Finally, the existing results for model transformations and synchronisations between two domains are lifted to the more general case of an arbitrary number of domains or models containing views, i.e., a model in one domain may be transformed to models in several domains or to all other views, respectively, and model updates in one domain may be synchronised to several other domains or to all other views, respectively.

Counting curves, and the stable length of currents

E-print/Working paper (2016)

Let $\gamma_0$ be a curve on a surface $\Sigma$ of genus $g$ and with $r$ boundary components and let $\pi_1(\Sigma)\curvearrowright X$ be a discrete and cocompact action on some metric space. We study the asymptotic behavior of the number of curves $\gamma$ of type $\gamma_0$ with translation length at most $L$ on $X$. For example, as an application, we derive that for any finite generating set $S$ of $\pi_1(\Sigma)$ the limit $$\lim_{L\to\infty}\frac 1{L^{6g-6+2r}}\{\gamma\text{ of type }\gamma_0\text{ with }S\text{-translation length}\le L\}$$ exists and is positive. The main new technical tool is that the function which associates to each curve its stable length with respect to the action on $X$ extends to a (unique) continuous and homogenous function on the space of currents. We prove that this is indeed the case for any action of a torsion free hyperbolic group. [less ▲]

La relation entre les jeux de la petite enfance et les intérêts professionnels.

L’intérêt des enfants pour leurs professions futures pourrait s’expliquer par le fait que les individus ont tendance à considérer hommes et femmes en catégories distinctes. Les enfants sont influencés par leur environnement qui se constitue, entre autre, par leurs parents, l'école, les médias, ainsi que par les jeux qu’on leur présente durant leur petite enfance. Dans cet article, nous allons présenter les résultats de deux études comparatives sur les jeux de la petite enfance ; d’une part auprès d’élèves du primaire et d’autre part auprès de lycéens. Dans l’échantillon des élèves du primaire, nous allons mettre les jeux de la petite enfance en relation avec les intérêts professionnels. Nous constatons dans cette étude que les jeux de la petite enfance ont une influence sur les choix professionnels. Pour que les intérêts professionnels se développent conformément à la personnalité de l’enfant, il serait donc préférable que celui-ci ait le choix entre une multitude de jeux, qui ne sont pas exclusivement liés aux stéréotypes de leur sexe. De cette façon, l’enfant aura la possibilité de développer ses propres choix et intérêts professionnels. [less ▲]

The Internet of Things (IoT) paradigm makes the Internet more pervasive. IoT devices are objects equipped with computing, storage and sensing capabilities and they are interconnected with communication technologies. Smart cities exploit the most advanced information technologies to improve public services. For being effective, smart cities require a massive amount of data, typically gathered from sensors. The application of the IoT paradigm to smart cities is an excellent solution to build sustainable Information and Communication Technology (ICT) platforms and to produce a large amount of data following Sensing as a Service (S^2aaS) business models. Having citizens involved in the process through mobile crowdsensing (MCS) techniques unleashes potential benefits as MCS augments the capabilities of existing sensing platforms. To this date, it remains an open challenge to quantify the costs the users sustain to contribute data with IoT devices such as the energy from the batteries and the amount of data generated at city-level. In this paper, we analyze existing solutions, we provide guidelines to design a large-scale urban level simulator and we present preliminary results from a prototype. [less ▲]
