[more ▼]In 1884 Willem Kloos and Albert Verwey started work on Julia, a collection of forty poems written in the manner of the successful author Fiore della Neve (M.G.L. van Loghem). In their pamphlet The Incompetence of the Dutch Literary Critics (1886), in which Julia’s true authorship was revealed, Kloos and Verwey made plain that the poems had been conceived as deliberate nonsense, something the Dutch literary establishment had failed to recognize. Nevertheless, a close reading of the collection brings to light a number of textual similarities with Kloos’s and Verwey’s serious poetry written in the period 1883-1885. This article reveals Julia as a fascinating hybrid in which an older aesthetic coexists with a new poetical language associated with the Eighties Movement.

[more ▼]We propose a learning approach to pre-compute K-armed bandit playing policies by exploiting prior information describing the class of problems targeted by the player. Our algorithm ﬁrst samples a set of K-armed bandit problems from the given prior, and then chooses in a space of candidate policies one that gives the best average performances over these problems. The candidate policies use an index for ranking the arms and pick at each play the arm with the highest index; the index for each arm is computed in the form of a linear combination of features describing the history of plays (e.g., number of draws, average reward, variance of rewards and higher order moments), and an estimation of distribution algorithm is used to determine its optimal parameters in the form of feature weights. We carry out simulations in the case where the prior assumes a ﬁxed number of Bernoulli arms, a ﬁxed horizon, and uniformly distributed parameters of the Bernoulli arms. These simulations show that learned strategies perform very well with respect to several other strategies previously proposed in the literature (UCB1, UCB2, UCB-V, KL-UCB and $\epsilon_n$-GREEDY); they also highlight the robustness of these strategies with respect to wrong prior information.

[more ▼]Le portail sculpté méridional de Mont-devant-Sassey est intéressant à plus d’un titre. Premièrement, il est le portail gothique lorrain le mieux conservé qui soit, comme la critique d’authenticité le confirme. Ensuite, certains des choix iconographiques effectués par le « commanditaire » sont surprenants, inusités, voire inédits. Enfin, en raison de sa situation géographique char- nière entre le domaine français et l’Empire germanique, les sculpteurs ont pu profiter des innovations sculpturales introduites tant à l’ouest qu’à l’est et les combiner de manière originale. Le présent article est l’occasion de renouveler l’identification iconographique de certaines figures, de proposer une datation de l’ensemble et de suggérer les transferts artistiques attestés par le portail (réception de formules iconographiques et stylistiques mises en place dans des grands centres).

[more ▼]Analytical method validation is a mandatory step to evaluate the ability of developed methods to provide accurate results for their routine application in order to trust the critical decisions that will be made with them. Even if several guidelines exist to help perform analytical method validations (ICH Q2R1 [1], USP <1225> [2], …) there is still the need to clarify the meaning and interpretation of analytical method validation criteria and methodology. Indeed, actually method validation is mostly realised as the traditional check list implementation of e.g. the ICH Q2R1 or USP <1225> method validation requirements. However, within the trend of Quality by Design [3], there is the need to switch from this traditional vision to an analytical method validation really adding value and providing a high level of assurance of analytical methods results reliability. Yet, different interpretations can be made of the validation guidelines as well as for the definitions of the validation criteria. This will lead to diverse experimental designs implemented to try fulfilling these criteria. Finally, different decision methodologies can also be interpreted from these guidelines. Therefore, the risk that a validated analytical method may be unfit for its future purpose will depend on a personal interpretation of these guidelines. The objective of this presentation is thus to show that analytical method validation should be planned and performed by first starting with the end in mind: what is the objective of the analytical methods under study? In such a way analytical method validation is coherent with the actual Quality by Design regulatory expectations. The risk of having validated an analytical method unfit for its purpose is strongly reduced as well as the risk of generating Out of Specification (OOS) results due to an unfit method.

[more ▼]Eddy current problems are addressed in a bidimensional setting where the conducting medium is non-magnetic and has a corner singularity. For any fixed parameter linked to the skin depth for a plane interface, we show that the flux density is bounded near the corner unlike the perfect conducting case. Then as goes to zero, the first two terms of a multiscale expansion of the magnetic potential are introduced to tackle the magneto-harmonic problem. The heuristics of the method are given and numerical computations illustrate the obtained accuracy.

[more ▼]Urban sprawl is a major issue for sustainable development. It represents a significant contribution to energy consumption of a territory especially due to transportation requirements. However, transport energy consumption is rarely taken into account when the sustainability of suburban structures is studied. In this context, the paper presents a method to estimate transport energy consumption in residential suburban areas. The study aimed, on this basis, at highlighting the most efficient strategies needed to promote awareness and to give practical hints on how to reduce transport energy consumption linked to urban sprawl in existing and future suburban neighborhoods. The method uses data collected by using empirical surveys and GIS. An application of this method is presented concerning the comparison of four suburban districts located in Belgium to demonstrate the advantages of the approach. The influence of several parameters, such as distance to work places and services, use of public transport and performance of the vehicles, are then discussed to allow a range of different development situations to be explored. The results of the case studies highlight that travelled distances, and thus a good mix between activities at the living area scale, are of primordial importance for the energy performance, whereas means of transport used is only of little impact. Improving the performance of the vehicles and favoring home-work give also significant energy savings. The method can be used when planning new areas or retrofitting existing ones, as well as promoting more sustainable life styles regarding transport habits.

[more ▼]The authors consider a power system composed of several non-synchronous AC areas connected by a multiterminal high-voltage direct current (HVDC) grid. In this context, the authors propose a distributed control scheme that modiﬁes the power injections from the different AC areas into the DC grid so as to make the system collectively react to load imbalances. This collective reaction allows each individual AC area to downscale its primary reserves. The scheme is inspired by algorithms for the consensus problem extensively studied by the control theory community. It modiﬁes the power injections based on frequency deviations of the AC areas so as to make them stay close to each other. A stability analysis of the closed-loop system is reported as well as simulation results on a benchmark power system with ﬁve AC areas. These results show that with proper tuning, the control scheme makes the frequency deviations converge rapidly to a common value following a load imbalance in an area.

[more ▼]The additional energy spread due to sample porosity was implemented in the SIMNRA simulation code, version 6.60 and higher. Deviations of the path length and energy loss distributions from the ones expected from a Poisson distribution of the number of traversed pores are taken into account. These deviations are due to the interaction of pores at higher pore concentrations by overlap or blocking. The skewnesses of the energy distributions are approximated by two-piece normal distributions with identical first three moments. Propagation of porosity-induced energy spread in thick layers is taken into account. Calculated results are compared to experimental data obtained with thin TiO2 mesoporous films measured by Rutherford backscattering (RBS),transmission electron microscopy (TEM), and atmospheric poroellipsometry.

La demande chinoise des matières premières latino-américaines combinée à une augmentation de la consommation interne et de l'investissement expliquent ces performances. Par ailleurs, des progrès ont été accompli en matière sociale. En outre, la région connaît une stabilité politique grâce à l'enracinement de la démocratie depuis plus de 20 ans. Toutefois, l'Amérique latine a encore pas mal de défis à relever: diversification économique et des débouchés; réduction des inégalités; lutte contre la criminalité organisée, la violence et la corruption.

[more ▼]Model parameterization through adjustment to ﬁeld data is a crucial step in the modeling and the understanding of the drainage network response to tectonic or climatic perturbations. Using as a test case a data set of 18 knickpoints that materialize the migration of a 0.7-Ma-old erosion wave in the Ourthe catchment of northern Ardennes (western Europe), we explore the impact of various data ﬁtting on the calibration of the stream power model of river incision, from which a simple knickpoint celerity equation is derived. Our results show that statistical least squares adjustments (or misﬁt functions) based either on the streamwise distances between observed and modeled knickpoint positions at time t or on differences between observed and modeled time at the actual knickpoint locations yield signiﬁcantly different values for the m and K parameters of the model. As there is no physical reason to prefer one of these approaches, an intermediate least-rectangles adjustment might at ﬁrst glance appear as the best compromise. However, the statistics of the analysis of 200 sets of synthetic knickpoints generated in the Ourthe catchment indicate that the timebased adjustment is the most capable of getting close to the true parameter values. Moreover, this ﬁtting method leads in all cases to an m value lower than that obtained from the classical distance adjustment (for example, 0.75 against 0.86 for the real case of the Ourthe catchment), corresponding to an increase in the non-linear character of the dependence of knickpoint celerity on discharge [less ▲]Detailed reference viewed: 51 (10 ULg) Cours de géologiePoty, Edouard Learning material (2012)Notes du cours de géologie de 1 bac en géologie et de 2 bac en géographieDetailed reference viewed: 234 (28 ULg)
