A l’heure où l’industrie cimentière est majoritairement responsable de la production de CO2 dans le secteur de la construction, il s’avère utile de compenser cette production par un phénomène inverse: la captation du CO2. Ce processus d’absorption de CO2, appelé carbonatation, améliore certaines propriétés du béton lors de la conversion du dioxyde de carbone CO2 en carbonate de calcium CaCO3. Les préoccupations environnementales actuelles motivent l’étude de la carbonatation dans le but de maximiser l'absorption du dioxyde de carbone. Les granulats recyclés, produits à base de déchets de béton concassés mécaniquement, peuvent prendre place dans de nouvelles applications en béton. Ils peuvent remplacer les granulats naturels en tout ou en partie, épargnant ainsi l’extraction des matières premières naturelles. La combinaison des deux approches vise à élaborer un produit dont l’impact environnemental est réduit au minimum. [less ▲]

Hundred and thirteen male adult albino rats (Wistar) have successively been submitted to 3 CFR, 3 FI 30, 3 FI 60, 3 FI 90 and 40 FI 120 seconds sessions. The daily sessions lasted in every case 30 minutes. Daily distributions of the Curvature Indice (Fry, Kelleher & Cook, 1960) values showed that the mean value increased up to a stabilization point at the 20th FI 120 seconds session and that the inter-individual differences as estimated by the standard deviation increased progressively throughout the session series. Rank correlations (Kendall Tau t) computed between individual Curvature Index values from adjacent or remote sessions were highly osgnificant and showed that the level of adjustment to the FI schedule early in training has a predictive value.

Turtle doves, pigeons and rats were trained on fixed-interval (FI) 2, 4, 6, 8- and 110-mi, schedules. Response rates were at each FI value, higher in both bird psecies. They decreased as FI value increased in rats and pigeons. Rat's curvature indices were in all cases superior to those of birds, and the turtle dove differed significantly from pigeons at 2, 4 and 6 min. Curvature indices decreased in rats and increased in birds (except for 2 turtle doves) as the FI value increased. These results question the traditionally assumed cross-species generality of performance in FI schedules. [less ▲]

Motivated by the problem of learning a linear regression model whose parameter is a large fixed-rank non-symmetric matrix, we consider the optimization of a smooth cost function defined on the set of fixed-rank matrices. We adopt the geometric optimization framework of optimization on Riemannian matrix manifolds. We study the underlying geometries of several well-known fixed-rank matrix factorizations and then exploit the Riemannian geometry of the search space in the design of a class of gradient descent and trust-region algorithms. The proposed algorithms generalize our previous results on fixed-rank symmetric positive semidefinite matrices, apply to a broad range of applications, scale to high-dimensional problems and confer a geometric basis to recent contributions on the learning of fixed-rank non-symmetric matrices. We make connections with existing algorithms in the context of low-rank matrix completion and discuss relative usefulness of the proposed framework. Numerical experiments suggest that the proposed algorithms compete with the state-of-the-art and that manifold optimization offers an effective and versatile framework for the design of machine learning algorithms that learn a fixed-rank matrix.

Drawing on a documentary analysis of two socio-economic policy programs, one Flemish (“Vlaanderen In Actie”), the other Walloon (“Marshall Plans”), and a discourse analysis of how these programs are received in one Flemish and one Francophone quality newspaper, this paper illustrates how Flanders and Wallonia both seek to become top-performing knowledge-based economies (KBEs). The paper discerns a number of discursive repertoires, such as “Catching up,” which policy actors draw on to legitimize or question the transformation of Flanders and Wallonia into KBEs. The “Catching up” repertoire places Flanders resolutely ahead of Wallonia in the global race towards knowledge, excellence, and growth, but suggests that Wallonia may, in due course, overtake Flanders as a top competitive region. Given the expectations and/or fears that “Catching up” evokes among Flemish and Walloon policy actors, the repertoire serves these actors as a flexible discursive resource to make sense of, and shape, their collective futures, and thus their identities. The primary aim of the paper is to underline the simultaneity of, and the interplay between, globalizing forces and particularizing tendencies, as Flanders and Wallonia develop with a global KBE in nation- or region-specific ways.
