François Jacqmin compte parmi les quelques deux ou trois plus grands poètes de Belgique. Toute l’écriture de celui qui a dit « la poésie sera consolatrice, ou rien » est une lutte contre les limites ou les illusions de la pensée et de la parole, une tentative de dépasser l’impuissance de la poésie à conserver trace de l’émerveillement de l’homme devant la nature. Réel et langage, désir et nihilisme sont les pôles d’une œuvre capitale. [less ▲]

Studies on nationalism were often interested with the city, especially the city centers. The politics of heritage, the architecture of public buildings and the design and use of central public spaces are often studied in relation to national identity politics. Municipal politics of the historical city in the face of central authorities’ urban politics is also frequently approached in the light of Nation-State building issues. If no doubt the consideration of city centers as a vantage point for understanding the relation between nationalism and the city is an interesting one that bore many fruits, we believe that a vantage point concentrating on the peripheries can highly contribute in unveiling other aspects of this relation. This paper aims at investigating the potentialities of this contribution. As the place where urbanization is taking place, the periphery is: - Where the national identity construction logic is put to test. First because, historically, it is here where the confrontation between the urban and the rural did first take place. Second, because rural exodus and migration, usually more important in the periphery, will continue to challenge it. - Where the city and the hinterland get connected through different national territory building networks. - Where the Nation-State central authorities will find the largest land reserves to develop their large emblematic projects. - Where urban fragmentation poses the strongest challenge to the unitarian message of nationalism, but also is where some nationalist movements might best develop In fact, the periphery represents equally a fertile ground for nationalism and for resistances to it. This paper will rely on the city of Beirut as a case study. [less ▲]

Analytical methods capability evaluation can be a useful methodology to assess the fitness of purpose of these methods for their future routine application. However, care on how to compute the capability indices has to be made. Indeed, the commonly used formulas to compute capability indices such as Cpk, will highly overestimate the true capability of the methods. Especially during methods validation or transfer, there are only few experiments performed and, using in these situations the commonly applied capability indices to declare a method as valid or as transferable to a receiving laboratory will conduct to inadequate decisions. In this work, an improved capability index, namely Cpk-tol and the corresponding estimator of proportion of non conforming results ( ) is proposed. Through Monte-Carlo simulations, they have been shown to greatly increase the estimation of analytical methods capability in particular in low sample size situations as encountered during methods validation or transfer. Additionally, the usefulness of this capability index is illustrated through several case studies covering applications commonly encountered in the pharmaceutical industry. Finally a methodology to determine the optimal sample size required to validate analytical methods is also given using the proposed capability metric. [less ▲]

A subproblem technique is applied to dual thin shell finite element formulations. Both the magnetic vector potential and magnetic field formulations are considered. The subproblem approach developed herein couples three problems: a simplified model with only inductors, a thin region problem using approximate interface conditions and a correction problem to improve the accuracy of the thin shell approximation, in particular near their edges and corners. Each problem has its own geometry and is solved on its associated finite element mesh. [less ▲]

The performance of several Internet applications often relies on the measurability of path similarity between different participants. In particular, the performance of content distribution networks mainly relies on the awareness of content sources topology information. It is commonly admitted nowadays that, in order to ensure either path redundancy or efficient content replication, topological similarities between sources is evaluated by exchanging raw traceroute data, and by a hop by hop comparison of the IP topology observed from the sources to the several hundred or thousands of destinations. In this paper, based on real data we collected, we advocate that path similarity comparisons between different Internet entities can be much simplified using lossy coding techniques, such as Bloom filters, to exchange compressed topology information. The technique we introduce to evaluate path similarity enforces both scalability and data confidentiality while maintaining a high level of accuracy. In addition, we demonstrate that our technique is scalable as it requires a small amount of active probing and is not targets dependent. [less ▲]

In this paper, we present an original environment, the Distributed Collaborative Design Studio (DCDS) which allows multimodal real-time remote exchanges, and which aims at re-creating remotely the conditions of co-present meetings. This environment associates a videoconference tool (supporting verbal and non-verbal communication) and an original real-time shared digital hand-drawn sketches system (supporting graphical communication). The users can import documents and annotate them in real-time at distance. In this paper, we are interested in studying the use of the graphical modality (digital sketch and document annotations) as a tool for collective design and remote communication. This study takes place in the framework of a collaborative architectural design studio, which has taken place during 3 month, and gathering students from Belgium and France to work together in 3 small groups mainly at distance. The study focuses on the role of graphical modality in the synchronous remote meetings supported by the DCDS. We identify the types of digital annotations made on the imported document, thanks to the electronic pen, and their role in the cognitive processes of designing and in the collaboration and communication processes. We also identify the different practices of digital sketching, according to the group and its collaborative strategies. We discuss the utility of the graphical modality as an efficient support for collaborative synchronous activities and show that the DCDS environment supports different strategies of collaborative design (co-design and distributed design). We conclude on recommendations for improving the system and for designing sketch-based collaborative environments. [less ▲]

Echocardiography has become a routine non invasive cardiac diagnostic tool in most species. Accurate measurement of cardiac dimensions requires reference values, which are poorly documented in goats. The aim of this study was to test the inter-day repeatability and to establish the reference values of two-dimensional (2D-) and time-motion (M-) mode echocardiographic variables in healthy adult Saanen goats. Six goats were investigated three times by the same observer at one day interval using a standardized 2D- and M-mode echocardiographic protocol. The intra-observer inter-day repeatability was tested using analysis of variance, calculation of the coefficient of variation and confidence intervals. A single echocardiographic examination was performed in 6 other goats, and values obtained in the 12 goats were used to establish the 2D- and M-mode echocardiographic reference values in healthy adult female Saanen goats. Statistical analysis revealed a good inter-day repeatability of the echocardiographic cardiac measurements. Echocardiographic reference values obtained in healthy adult Saanen goats seemed slightly higher than those reported in healthy Swedish domestic goats and were similar to those reported in healthy adult sheep.

One of the biggest upcoming challenges concerning both environmental and energy systems engineering is the control and limitation of greenhouse gas emissions due to human activity. Fossil fuels-fired power plants are in this context one of the main contributors due to the large amounts of CO2 emitted. Different technologies have been developed for capturing CO2 from such power plants. This work focuses on post-combustion CO2 capture by reactive absorption into amine solvents like monoethanolamine (MEA). The main drawback of this technology is actually the high energy requirement of the process, especially for solvent regeneration. It is then highly interesting to model the capture process so that optimal operating conditions could be approached by simulation thus reducing the number of expensive experimental tests. Thanks to the simulation, it has been possible to identify the most influent process variables and to optimize their value. It was also possible to study the impact of process modifications on the global capture efficiency. The improvements studied allowed for a reduction by up to 14% of the process exergy consumption. Another major drawback of the post-combustion CO2 capture is solvent degradation, which can be due to thermal as well as oxidative mechanisms. Degradation affects the CO2 capture process since it may cause corrosion, foaming and fouling, possibly inducing a decrease of the solvent efficiency and high additional operating costs due to solvent replacement. In order to study degradation of conventional amine solvents as well as degradation of novel solvents, a degradation test rig has been built at the University of Liège in collaboration with the company Laborelec, member of the GDF SUEZ group. First results show that degradation obtained on this lab installation can be compared to degradation results observed on CO2 capture pilot installation. The final objective of this thesis is to make a link between degradation and simulation. Experimental data obtained on the degradation test rig will be implemented into the existing simulation model so that optimal operating conditions considering both process energy efficiency and solvent degradation can be determined.
