In this paper we investigate an event-driven Inter-Vehicle Communication protocol to mitigate shock waves in dense traffic situation. From previous work we know that flooding or frequent beaconing require excessive network resources. To overcome this limitation we focus on an efficient message exchange mechanism requiring as few network resources as possible, while still providing timely and accurate traffic information. We designed Density Redistribution through Intelligent Velocity Estimation (DRIVE), an event-driven Inter-Vehicle Communication protocol that learns about traffic conditions ahead and recommends optimal velocities in order to prevent the formation of vehicular shock waves. We demonstrate that our approach of reacting in case of traffic fluctuations leads to significant improvements in overall traffic flow. Furthermore we show that even a low number of equipped vehicles is sufficient to achieve this target. [less ▲]

When implementing the high-level control component of an autonomous robot, one needs to process events, generated by sensory components, to extract the information relevant to the control component. This paper discusses the lack of support for event-processing when current agent programming languages (APLs) are used to implement the control component of autonomous robots. To address this issue, the use of information flow processing (IFP) systems is proposed to support the development of event-processing components (EPCs) for an autonomous robot. The necessary interaction mechanisms between a control component and EPCs are defined. These mechanisms allow run-time subscription to events of interest, asynchronous reception of events, maintaining necessary histories of events and run-time querying of the histories. Several implementation-related concerns for these interaction mechanisms are discussed. [less ▲]

If you are reading these lines, you are probably curious about the type of experience that you would have as an attendee of this talk. You might wonder whether the topic would match your interests, whether the speaker will be good enough to satisfy your expectations, whether you will feel inspired, exhilarated, or whether you will have concrete tools to bring back to your work. While you are usually the ones shaping people’s experiences, you are striving for nice experiences as well. Designing for human experiences is one of the most challenging yet fascinating activities. It is a responsibility that we should embrace with humility and dedication. To face the complexity of our mission, we need to draw on theoretical knowledge, methodological skills and of course on our shared professional expertise, as a community. While UX practitioners are working hard at the front lines to design better products or services, scientists work in the shadows to develop and consolidate a myriad of novel and highly valuable UX methods. During this talk, you will discover the ever-growing UX toolbox that could greatly support you in collecting richer, insightful and more valid data. From scientific theories to pragmatic methods, from academia to industry, from Luxembourg to Puerto Rico… Eventually everything connects. [less ▲]

Progress in market integration over the past two decades has come at the expense of growing flexibility in the laws that govern the singlemarket (SM) as well as the way that these laws are implemented. This differentiated integration comes in four forms: soft; informal; multi-speed; and opt-out differentiation. We examine how the completion of the SM has been held back in the varied implementation of EU competition policy and variation in national corporate law, energy markets, services and taxation. These sectors and issue areas form the frontier in which the main political struggles over the future shape of the SM take place, and in which differentiation is most clearly manifested. The SM notion supposedly entails a concrete set of substantive policy commitments that form the basis of the ‘ever closer union’. However, increasing differentiation undermines the identification of the EU’s core constitutional commitments. [less ▲]

We show that every quasitrivial n-ary semigroup is reducible to a binary semigroup, and we provide necessary and sufficient conditions for such a reduction to be unique. These results are then refined in the case of symmetric n-ary semigroups. We also explicitly determine the sizes of these classes when the semigroups are defined on finite sets. As a byproduct of these enumerations, we obtain several new integer sequences. [less ▲]

Luxembourg – international financial center, European administrative center, destination country for immigration? This empirical study provides insights about a society that has hitherto largely eluded scientific investigation and observes the processes of identity construction in globalised conditions. The interdisciplinary team of authors exposes the processes of subjective appropriations and institutional attributions at work in the fields of languages, spaces, perceptions of self and others as well as everyday cultures, and identifies for the first time socio-cultural milieus in the Grand Duchy. The findings of the three-year research project uncover the ambivalences and dynamics of a multicultural and multilingual society. [less ▲]

For rural areas the utilisation of renewable energies can support a prosperous development. Economic practices are increasingly important for understanding changes in this sector. The interplay of economic practices with corporate and governmental policies is related to questions of space and scale, such as: which everyday economic practices form energy markets changes; which conditions frame regional policies and practices; which processes of regionalisations evolve? The core interests of the paper are to analyse processes of constitution and reproduction of different types of energy regions and markets, and how practices and policies of such “energetic regionalisations“ intertwine – applying a multi-theory and multi-method (Interviews, Document Analysis) approach, focussing on biogas production in Luxembourg and Germany. I examine institutional and structural conditions that frame processes of regionalisations in the biogas economy and how these relate to socio-technical developments – based on evolutionary institutionalism and socio-technical transition studies. Important elements are: (1) The dynamic dimension of frameworks; (2) the concurrence of political, social, economic and technical processes; (3) the spatial differences of energy related policies. Economic practices in the biogas economy (e.g. by operators, investors) are another part of investigation - following the theory of Everyday Regionalisations. The important elements here are: (1) The constitution and reproduction of regions through economic practices; and (2) the threefold relationship between economic practices and governmental energy policies as: (a) policies supporting or restricting practices; (b) practices producing and restructuring policies – and regional markets; and (c) policies as environmental drivers for practices – and vice versa. The paper focuses on the conceptual framework of an ongoing research project. Preliminary results from the field study will be presented. [less ▲]

The article analyses the composition of colour in the mise-en-scène of the zombie-movies REC, 28 Days Later and World War Z via a computer based approach. It first evaluates some of the methodological problems of common colour-quantisation by using clustering-algorithms in the context of film studies, then a new developed process is presented which builds on the theory of colour contrasts by Johannes Itten. A simple statistical analysis of two contrast ratios for each of the movies demonstrates that this approach is capable of providing detailed insights into the composition of colour in movies in general. Furthermore, the analysis of the three movies reveals that the accentuation of colour contrast relations serves different functions: colours can support the narrative structure of the movie, emphasize repeating motifs or establish an autonomous aesthetic space.

Two areas in the human occipito-temporal cortex respond preferentially to faces: 'the fusiform face area' ('FFA') and the 'occipital face area' ('OFA'). However, it is unclear whether these areas have an exclusive role in processing faces, or if sub-maximal responses in other visual areas such as the lateral occipital complex (LOC) are also involved. To clarify this issue, we tested a brain-damaged patient (PS) presenting a face-selective impairment with functional magnetic resonance imaging (fMRI). The right hemisphere lesion of the prosopagnosic patient encompasses the 'OFA' but preserves the 'FFA' and LOC. Using fMRI-adaptation, we found a larger response to different faces than repeated faces in the ventral part of the LOC both for normals and the patient, next to her right hemisphere lesion. This observation indicates that following prosopagnosia, areas that do not respond preferentially to faces such as the ventral part of the LOC (vLOC) may still be recruited to subtend residual perception of individual faces.

Temperature dependences of the dielectric constants [epsilon]i and of the birefringences [Delta]ni for light propagation directions along all the three crystallographic axes (i = a, b, c) have been measured between 5 and 350 K. The optical measurements clearly reveal a new phase transition at TL = 75 K, below which the crystal structure is transformed from the ferroelectric Pna21 phase into an unknown low temperature phase, possibly the monoclinic space group P1121. Small peaks in the dielectric constants [epsilon]a and [epsilon]b have been observed at this transition temperature. [less ▲]
