Adaptive facades can ensure step-change progresses in the energy efficiency and the use of renewable energy while improving the comfort of the occupants. Therefore, the purpose of this structured interview is to assess advantages, disadvantages and future expectations considering the adaptive facades. This work is a part of actions of The COST Action TU1403 Adaptive Façade Network. The objective of this report is to gain an understanding of how experts currently define adaptive façade systems, which simulation tools they use, the major strengths, weaknesses, opportunities and treats of adaptive façade systems, key performance indicators they use and their vision for the future of adaptive facades. With this information gathered, it is anticipated that adaptive façade professionals will carry on assessment of adaptive facades. A qualitative study design was employed, using semi-structured interviews. Interviewees working in academia and practice were selected. The interviewees represented the range of possible adaptive facade professionals, from researchers and designers considered optimization in the assessment of adaptive facades. Also, every interviewed expert was asked to approve their responses and add any additional comment to their answers. [less ▲]

According to Jennifer A. Peeples, the “toxic sublime” refers to “the tensions that arise from recognizing the toxicity of a place, object or situation, while simultaneously appreciating its mystery, magnificence and ability to inspire awe”. As an alternative to the “technological sublime”, which creates awe through the contemplation of human efforts to master the environment, it urges us to consider the negative and noxious aspects of such endeavours. Through her analysis of Edward Burtynsky’s “Manufactured Landscapes”, Peeples introduces a new form of sublime aesthetics, which may also be used as a valuable trope in the study of the relationship between literature and our physical environment. My goal in this study is to extend such considerations to the recent history of American literature, using examples such as Rachel Carson’s “A Fable for Tomorrow” (1962), which describes the invisible “lethal film” made of “systemic insecticides” that converts natural species into carcinogenic poison, thus depicting landscapes as intoxicated “places of beauty” that no longer symbolise human abilities to dominate the environment but rather their lack of control over it. Likewise, in Don DeLillo’s novel White Noise (1985), the protagonist Jack Gladney experiences his daughter’s “utterance” of the car brand “Toyota Celica” as “beautiful and mysterious”, which “str[ikes] [him] with the impact of a moment of splendid transcendence”. Gladney then proceeds to relate his family’s “garbage” to his relatives’ selves as it is a “sign[] of [their] deepest nature”. Jack’s approach to human waste shows that what Cynthia Deitering defines as the “toxic consciousness”—the general awareness of the existence of toxicity in the landscape—is to be associated with the protagonist’s idea of “consumer consciousness”. Indeed, the term toxicity can also metaphorically refer to the “poisoned” nature of our relationship to and perception of specific places, objects, or situations. The viewer in national parks, for instance, tends to see the “sublime landscape” as a “series of picturesque scenes”, which allows him to consume the scene as an “object of artistic consumption”. Such examples point to different but related ways of examining distinct forms of toxicity that characterise our relationship with our physical environment. They also prompt us to examine the problematic nature of technology and progress while dealing with the elusive and paradoxical nature of the technological sublime. [less ▲]

In many applications, and in systems/synthetic biology in particular, it is desirable to compute control policies that force the trajectory of a bistable system from one equilibrium (the initial point) to another equilibrium (the target point), or in other words to solve the switching problem. It was recently shown that, for monotone bistable systems, this problem admits easyto-implement open-loop solutions in terms of temporal pulses (i.e., step functions of fixed length and fixed magnitude). In this paper, we develop this idea further and formulate a problem of convergence to an equilibrium from an arbitrary initial point. We show that this problem can be solved using a static optimization problem in the case of monotone systems. Changing the initial point to an arbitrary state allows to build closed-loop, event-based or open-loop policies for the switching/convergence problems. In our derivations we exploit the Koopman operator, which offers a linear infinite-dimensional representation of an autonomous nonlinear system. One of the main advantages of using the Koopman operator is the powerful computational tools developed for this framework. Besides the presence of numerical solutions, the switching/convergence problem can also serve as a building block for solving more complicated control problems and can potentially be applied to non-monotone systems. We illustrate this argument on the problem of synchronizing cardiac cells by defibrillation. Potentially, our approach can be extended to problems with different parametrizations of control signals since the only fundamental limitation is the finite time application of the control signal.

In the wake of financial and economic crises, the European Union took unprecedented steps to build an institutional framework accompanying financial market governance. This chapter will outline the EU law techniques used to integrate Member States’ interests in the set-up and functioning of that framework. Following a brief overview and recapitulation of the ‘more Europe’ developments having taken shape in the wake of crisis, the chapter will proceed in summarising how Member States’ interests have been embedded directly within the post-crisis EU regulation framework. It will be submitted that two different and complementary kinds of ‘interest inclusion’ techniques can be distilled, more or less explicitly, within the newly created financial market supervision frameworks. The inclusion and presumed safeguarding of Member States’ interests by virtue of administrative law tools is not entirely unproblematic. The final section of the chapter highlights challenges associated with such interest-inclusion approach and questions whether the a modest way forward in an attempt better to legitimate the current interest inclusion techniques by the EU institutions.

The paper explores the interaction between different kinds of social agents in the funding and management of cult foundations for the dead in the late-classical and Hellenistic period. Textual and archaeological dossiers will be discussed in order to 1) investigate the occupation of sacred space in existing sanctuaries and other public spaces as well as the creation of new sacred places, specifically meant to host ritual practice for dead individuals or groups; 2) provide a comparative analysis of the patterns of establishment, funding and management of cult foundations pertaining to civic, royal, individual or groups' initiatives; 3) explore the forms of interaction between various agents involved, e.g. between civic and private initiative in funding and management. When possible, these considerations will also be integrated with an evaluation of the religious status attributed to the honoured persons, with particular attention to the semantic fields of heroization and deification. Thus an attempt will be made at tracking down possible general trends of religious administration beyond local particularities, and at schematizing these configurations in a model taking into account four factors: the social status of ritual agents and recipients; the religious status acknowledged to cult recipients; the methods of funding and management; the degree of monumentalization and social impact of the cult foundations.

Structural fire engineering has long relied on a prescriptive approach based on isolated member behavior under continuously heating standard fire. By definition, this approach does not allow comprehending the effects of interaction between members of a complete structure nor the effects of real fire exposure. Yet, such effects can have a significant influence on the response of real buildings to fire. Notably, when a structure has survived a fully developed fire, the cooling phase that inevitably follows generates effects that may endanger the structure stability. This has been attested by real structural collapses and poses a specific threat to firefighters. However, the behavior of structures under natural fire and the causes of failure during cooling are still not well understood. This research investigates the response of steel-framed structures to natural fires with the aim to analyze the possible collapse mechanisms during cooling. Numerical simulations by nonlinear finite element method are conducted for different fire scenarios and structural designs. The simulations model the thermo-mechanical behavior of the frames accounting for the interaction between members during the entire fire duration until burnout. Different collapse mechanisms during cooling are highlighted and discussed, including connection failure and progressive collapse under localized fire. In the latter case, collapse of members not directly affected by the fire occurs during the cooling phase. These mechanisms result from a complex combination of several factors, such as the recovery of thermal elongation, the recovery of stiffness, and the prior development of permanent strains in the heated members. The results show that steel-framed structures are subject to collapse during the cooling phase of natural fires. Therefore, natural fires with heating-cooling sequences represent a loading case that should be considered in structural fire analyses and could lead to specific design provisions to prevent the occurrence of collapse during cooling.

Le travailleur du futur et la loi A quoi ressemble le travailleur de demain dans un monde où règnent toujours davantage les technologies de l’information ? Cette question est envisagée sous deux angles. Tout d’abord, l’économie numérique a fait naitre de nouvelles formes de production et d’emploi, telles que « l’économie des plateformes » (Uber, Deliveroo, ….). Celle-ci présente divers atouts pour les entreprises et pour les travailleurs, notamment en termes de flexibilité, mais elles est aussi la source de nouvelles formes de travail précaire. Le travailleur de demain est-il un travailleur du numérique sans protection sociale ? Le deuxième angle est celui du travailleur hyperconnecté. Faut-il envisager de créer un droit à la déconnexion ?

Comme les écosystèmes dulçaquicoles, les écosystèmes marins sont soumis à une pression humaine croissante qui altère la qualité de l’eau et les communautés aquatiques. Près de 98 pourcents de l’eau de notre planète bleue est contenue dans les océans qui constituent le réceptacle final de tout ce que nous rejetons comme déchets (volontairement ou non). Moins accessible, les océans sont méconnus, souvent oubliés ou négligés et considérés comme une zone inépuisable et où tout se dilue ; actuellement encore 80% des eaux usées sont rejetées en mer sans traitement préalable, à peine 2 % des surfaces marines sont protégées. La Méditerranée est particulière à plus d’un égard, bassin de concentration, de faible surface (1% des océans) abritant pourtant plus de 10% de la biodiversité mondiale. Cette petite mer est un modèle pour les océanographes : en mesurant ce qui s’y passe, nous pouvons prédire ce que se déroulera à court ou moyen terme dans le reste des océans. Le laboratoire d’Océanologie est activement impliqué depuis une quinzaine d’années dans la mise au point d’indice de la qualité des masses d’eau côtières. Ces indices sont construits sur base des connaissances du milieu (variations naturelles), par la mesure des niveaux de contamination et des effets (observation et contamination en mésocosme) de cette pollution sur les communautés. Nous avons développé et validé des indices biologiques (PREI : Posidonia Rapid and Easy Index, ICAR Indice Caulerpa cylindracea ; espèce envahissante), de pollution (TEPI : Trace Element Pollution Index, TESVI : Trace Element Spatial Variation Index), de qualité paysagère (LIMA LIttoral MArin) … Ces indices sont utilisés actuellement dans le cadre de la DCE (Directive Cadre Eau), la DCSMM (Directive Cadre Stratégie pour le Milieu Marin) et dans des réseaux de surveillance en Méditerranée, ils sont un relais et un moyen de communication entre les scientifiques et les politiques, les gestionnaires. L’exportation et l’apprentissage de l’utilisation de ces indices sont un atout pour une gestion globale de l’eau à l’échelle de la Méditerranée. Leurs applications sur l’ensemble de la façade méditerranéenne ont, entre autre, mis en évidence l’impact positif de l’application de directives européennes en matière de gestion des eaux par rapport aux côtes de Nord de l’Afrique.
