In 2010, Le Bot et al presented a free and open-access software (Data Analysis of Root Tracings - DART) allowing the analysis of complex root system architectures from captured images, particularly across time series. Using this software, a user has to manually identify roots as a set of links. After vectorization of a root system, three final data sets (RAC, TPS and LIE) can be exported as table files containing several attributes for (a) each individual root (e.g. root length), (b) each observation day or (c) each point used to construct the vectorized root system respectively. These data sets can finally be used either to calculate derived root system architecture (RSA) parameters or to draw the root system architecture at selected observation dates. However when an experiment involves the analysis and comparison of many root systems, the calculation of RSA parameters for each data set and the drawing of the corresponding vectorized root systems become time-consuming. In this context, we developed a R package, called archiDART, allowing both the automatic calculation of common root architecture parameters and the X-Y plotting of vectorized root systems for selected observation dates.

Background and Aims In order to analyse root system architectures (RSAs) from captured images, a variety of manual (e.g. Data Analysis of Root Tracings, DART), semi-automated and fully automated software packages have been developed. These tools offer complementary approaches to study RSAs and the use of the Root System Markup Language (RSML) to store RSA data makes the comparison of measurements obtained with different (semi-) automated root imaging platforms easier. The throughput of the data analysis process using exported RSA data, however, should benefit greatly from batch analysis in a generic data analysis environment (R software). Methods We developed an R package (archiDART) with five functions. It computes global RSA traits, root growth rates, root growth directions and trajectories, and lateral root distribution from DART-generated and/or RSML files. It also has specific plotting functions designed to visualise the dynamics of root system growth. Results The results demonstrated the ability of the package’s functions to compute relevant traits for three contrasted RSAs (Brachypodium distachyon [L.] P. Beauv., Hevea brasiliensis Müll. Arg. and Solanum lycopersicum L.). Conclusions This work extends the DART software package and other image analysis tools supporting the RSML format, enabling users to easily calculate a number of RSA traits in a generic data analysis environment.

Copulas enable to specify multivariate distributions with given marginals. Various parametric proposals were made in the literature for these quantities, mainly in the bivariate case. They can be systematically derived from multivariate distributions with known marginals, yielding e.g. the normal and the Student copulas. Alternatively, one can restrict his/her interest to a sub-family of copulas named Archimedean. They are characterized by a strictly decreasing convex function on (0, 1) which tends to +infinity at 0 (when strict) and which is 0 at 1. A ratio approximation of the generator and of its first derivative using B-splines is proposed and the associated parameters estimated using Markov chains Monte Carlo methods. The estimation is reasonably quick. The fitted generator is smooth and parametric. The generated chain(s) can be used to build "credible envelopes" for the above ratio function and derived quantities such as Kendall's tau, posterior predictive probabilities, etc. Parameters associated to parametric models for the marginals can be estimated jointly with the copula parameters. This is an interesting alternative to the popular two-step procedure which assumes that the regression parameters are fixed known quantities when it comes to copula parameter(s) estimation. A simulation study is performed to evaluate the approach. The practical utility of the method is illustrated by a basic analysis of the dependence structure underlying the diastolic and the systolic blood pressures in male subjects. (C) 2007 Elsevier B.V.

A wide range of scientifically validated Building Performance Simulation tools BPS is available internationally. The users of those tools are mainly researchers, physicists and experts who value empirical validation, analytical verification and calibration of uncertainty as defined by e.g. BESTEST. However, literature and comparative surveys indicate that most architects who use BPS tools in design practice are much more concerned with the (1) Usability and Information Management (UIM) of interface and (2) the Integration of Intelligent design Knowledge-Base (IIKB). Those two issues are the main factors for identifying a building simulation program as “Architect Friendly”. Now, with the advancement of BPS tools and the recent announcements of direct links between BIM or non-BIM modeling tools and BPS tools it is important to compare the existing programs. Based on an online survey, this paper presents the results of comparing ten major BPS tools. The following programs are compared: ECOTECT, HEED, Energy 10, Design Builder, eQUEST, DOE-2, Green Building Studio, IES VE, Energy Plus and Energy Plus-SketchUp Plugin (OpenStudio). With 249 valid responses, the survey ranked the tools in three classes and revealed that architects seek the IIKB above the UIM of the interface. Finally, the paper summarizes the key findings and underlines the major requirements for future improvement and development of BPS tools, mainly from an architectural perspective. [less ▲]

The Architect Gustave Serrurier-Bovy (1858-1910) L’architecte Gustave Serrurier-Bovy (1858-1910) Architect by vocation and formation, then merchant, and after that designer and industrialist, Gustave Serrurier, aka Serrurier-Bovy, is mostly known as a producer of furniture. Although more marginal, his architectural work are far from negligible. After 1888, and a couple of youthful projects, the architect from Liège most probably only does interior furnishings, but these prove to be considerable. For example, he brilliantly remodels the space and interior organization of the castle of La Cheyrelle (1903-1909) in the Cantal region of France. Just before, in 1902, he draws again the plans of an entire villa – his personal villa – which seems to function as a manifesto for an architecture different from Art Nouveau. Theoretician and utopian, he also develops a social reflection which leads him to think that architecture and furniture are interconnected practices, particularly apt to better the conditions of existence, notably of the less healthy. He applies and shows it in the furnishings of a workers housing complex in a competition organized on the occasion of the Liège World’s Fair in 1905. In his built work, through his spatial inventions and his sober and functional decoration, Serrurier opens perspectives onto a new art of life in the 20th century, and he anticipates thus the social, technical and artistic preoccupations of the Modern Movement. L’architecte Gustave Serrurier-Bovy (1858-1910) Architecte par vocation et formation, puis commerçant, ensuite créateur et industriel, Gustave Serrurier, dit Serrurier-Bovy, est surtout connu pour sa production de mobilier. Plus marginal, son travail d’architecte est pourtant loin d’être négligeable. Au-delà de 1888, après quelques œuvres de jeunesse, l’architecte liégeois ne réalise sans doute plus que des aménagements d’intérieurs, mais ceux-ci peuvent s’avérer considérables. Par exemple, il remodèle brillamment l’espace et la distribution intérieure du château de La Cheyrelle (1903-1909) dans le Cantal, en France. Juste avant, en 1902, on le voit dresser à nouveau les plans complets d’une villa – sa villa personnelle – qui sonne alors comme un manifeste pour une architecture différente de l’Art nouveau. Théoricien et utopiste, il développe aussi une réflexion sociale qui le conduit à penser qu’architecture et mobilier sont des pratiques liées, particulièrement propres à améliorer les conditions de l’existence, notamment des moins nantis. Il le prouve et l’expérimente encore dans l’aménagement d’un logement ouvrier lors du concours organisé à l’occasion de l’Exposition universelle de Liège en 1905. Dans son œuvre construite, par ses inventions spatiales, par sa décoration retenue et fonctionnelle, Serrurier ouvre des perspectives sur un nouvel art de vivre au 20e siècle et anticipe les préoccupations sociales, techniques et artistiques du Mouvement moderne.

Late modernity and its corollary, cultural capitalism, demand that everybody adopt self-sculpture as a life project. This phenomenon, which Bell describes as an « aesthetic justification of everyday life», seems to have led cities to exhibit themselves as well –in a Bilbao effect - and architecture to put on a show of itself. But what becomes of the artistic field’s limits and of beauty in the face of this new contemporary injunction? These are the questions we intend to tackle as a contribution to the seminar on venustas in the age of world market. [less ▲]

S’inscrivant dans un contexte complexe, la production architecturale des années 1930 offre un visage bigarré reflétant les bouleversements technologiques, formels, politiques et sociaux d’une société en quête de stabilité. Les innovations de la nouvelle architecture développées au lendemain de la guerre trouvent peu d’écho à Liège. Alors que des personnalités comme Huib Hoste ou Victor Bourgeois se lancent dans un rationalisme d’inspiration internationale, Liège continue de miser sur le régionalisme ou sur le style Beaux-arts. Il faut attendre la fin des années 1920 pour voir apparaître les premiers signes d’une remise en question des principes académiques. La conférence replacera en premier lieu l’architecture au centre du débat culturel. L’analyse de la scène éditoriale liégeoise permettra notamment d’identifier précisément les tensions qui ont animé la scène professionnelle locale et qui ont largement débordé du cadre restreint de l’architecture. Au niveau de la production, l’exposé abordera plusieurs typologies qui ont marqué les années 1930 comme le logement social, l’habitation unifamiliale, l’immeuble à appartements ou les infrastructures publiques.
