Vers une plateforme sémantique pour l'apprentissage adaptatif et collaboratif en ligne

Dans le monde de la formation en ligne, les systèmes d'apprentissage ont cherché à proposer un contenu adapté à tout utilisateur selon son profil.Cette adaptation a comme objectif général de permettre à l'apprenant de tirer le meilleur parti du contenu exposé des ressources d'apprentissage.Cependant, du point de vue de la collaboration entre apprenants selon l'adaptation au profil des apprenants, cette adaptation n'a pas été suffisamment explorée comme un aspect important du processus d'apprentissage en ligne.L'adaptation va permettre de grouper des utilisateurs de profil similaire ou très proche pour apprendre en harmonie tout en gardant la motivation et l'engagement nécessaire afin d'augmenter le taux de réussite des apprenants. Cet état de fait doit permettre aussi de réutiliser certains parcours d'apprentissage avec de bons taux de réussite pour de futures recommandations aux utilisateurs ayant le même profil. Dans cet article, nous mettons l'accent sur cet aspect et proposons un système d'apprentissage qui recommande des parcours d'apprentissage adaptés au profil des utilisateurs et qui permet un apprentissage collaboratif des utilisateurs de façon synchrone. Après un tour d'horizon de l'existant dans le domaine de l'apprentissage adaptatif en ligne, nous proposerons une architecture pour le pilotage de ce type d'apprentissage adaptatif collaboratif. Cette solution est fondée sur des ontologies et orchestrée par un système multi-agents. Ce dernier est responsable du pilotage des parcours d'apprentissage, de la recommandation de parcours en mode collaboratif ou non par le biais d'une communication entre les différents agents intervenants et de la gestion des événements captés par le système.

Amélioration de la visite de classe de l'enseignement technique : intégration d'un dispositif de médiation

L’amélioration des pratiques de l’enseignant est portée par la visite de classe effectuée par le conseil pédagogique. Cet article présente l’intégration d’un système de partage de document comme un dispositif de médiation dans la visite de classe. Ce système de partage permet d’améliorer les interactions entre l’enseignant et le conseil pédagogique sur l’élaboration des principaux documents pédagogiques relatif à la visite de classe. L’expérimentation a été réalisée avec le service de partage de documents Google Drive sur une population constituée d’une quinzaine d’enseignants et de trois encadreurs pédagogiques de l’enseignement technique. Les résultats ont montré une amélioration de la qualité pédagogique de la visite de classe et une amélioration de la communication entre l’enseignant et l’encadreur pédagogique. Il ressort de cette étude que l’enseignant devient moins stressé et il sollicite beaucoup plus le conseil pédagogique que lorsqu’il n’utilise pas ce dispositif.

Rook placements in $G_2$ and $F_4$ and associated coadjoint orbits

Let $\mathfrak{n}$ be a maximal nilpotent subalgebra of a simple complex Lie algebra with root system $\Phi$. A subset $D$ of the set $\Phi^+$ of positive roots is called a rook placement if it consists of roots with pairwise non-positive scalar products. To each rook placement $D$ and each map $\xi$ from $D$ to the set $\mathbb{C}^{\times}$ of nonzero complex numbers one can naturally assign the coadjoint orbit $\Omega_{D,\xi}$ in the dual space $\mathfrak{n}^*$. By definition, $\Omega_{D,\xi}$ is the orbit of $f_{D,\xi}$, where $f_{D,\xi}$ is the sum of root covectors $e_{\alpha}^*$ multiplied by $\xi(\alpha)$, $\alpha\in D$. (In fact, almost all coadjoint orbits studied at the moment have such a form for certain $D$ and $\xi$.) It follows from the results of Andr\`e that if $\xi_1$ and $\xi_2$ are distinct maps from $D$ to $\mathbb{C}^{\times}$ then $\Omega_{D,\xi_1}$ and $\Omega_{D,\xi_2}$ do not coincide for classical root systems $\Phi$. We prove that this is true if $\Phi$ is of type $G_2$, or if $\Phi$ is of type $F_4$ and $D$ is orthogonal.

Cyclicity of the 2-class group of the first Hilbert 2-class field of some number fields

Let $\mathds{k}$ be a real quadratic number field. Denote by $\mathrm{Cl}_2(\mathds{k})$ its $2$-class group and by $\mathds{k}_2^{(1)}$ (resp. $\mathds{k}_2^{(2)}$) its first (resp. second) Hilbert $2$-class field. The aim of this paper is to study, for a real quadratic number field whose discriminant is divisible by one prime number congruent to $3$ modulo 4, the metacyclicity of $G=\mathrm{Gal}(\mathds{k}_2^{(2)}/\mathds{k})$ and the cyclicity of $\mathrm{Gal}(\mathds{k}_2^{(2)}/\mathds{k}_2^{(1)})$ whenever the rank of $\mathrm{Cl}_2(\mathds{k})$ is $2$, and the $4$-rank of $\mathrm{Cl}_2(\mathds{k})$ is $1$.

Cops and Robbers on Dynamic Graphs: Offline and Online Case

We examine the classic game of Cops and Robbers played on models of dynamic graphs, that is, graphs evolving over discrete time steps. At each time step, a graph instance is generated as a subgraph of the underlying graph of the model. The cops and the robber take their turns on the current graph instance. The cops win if they can capture the robber at some point in time. Otherwise, the robber wins. In the offline case, the players are fully aware of the evolution sequence, up to some finite time horizon T. We provide a O(n 2k+1 T) algorithm to decide whether a given evolution sequence for an underlying graph with n vertices is k-cop-win via a reduction to a reachability game. In the online case, there is no knowledge of the evolution sequence, and the game might go on forever. Also, each generated instance is required to be connected. We provide a nearly tight characterization for sparse underlying graphs, i.e., with at most linear number of edges. We prove λ + 1 cops suffice to capture the robber in any underlying graph with n − 1 + λ edges. Further, we define a family of underlying graphs with n−1+λ edges where λ−1 cops are necessary (and sufficient) for capture.

Variabilité spatiale de la qualité des eaux agricoles d’un bassin versant de deux arrondissements d’Antananarivo (Madagascar)

Contexte : L’analyse spatiale de la qualité des eaux a été réalisée dans la zone agricole située dans un bas-fond d’un bassin versant de Tana 2 et Tana 4 – Madagascar. Objectif : Elle vise à déterminer la nature des eaux agricoles et la variabilité spatiale de leur alcalinité, leur salinité et leur teneur en matière organique. Méthodes : La zone agricole a été subdivisée en trois parcelles P1, P2 et P3 selon le type de sol. Des échantillons d’eaux prélevés sur les 43 points géo référencés de cette zone ont été soumis aux mesures de pH, Conductivité Électrique (CE) et Demande Chimique en Oxygène (DCO). La distribution spatiale de ces paramètres a été établie par interpolation des valeurs de ces indicateurs en utilisant v.kriging du logiciel GRASS GIS. Résultats et discussion : Les eaux des parcelles P2 présentent une forte alcalinité. Celles de la parcelle P3 sont très riches en sels dissous et en matières organiques. La distribution spatiale de l’alcalinité et la salinité suit un modèle linéaire, tandis qu’un modèle exponentiel caractérise la répartition de la matière organique.

ETUDE DE LA GESTION ACTUELLE DES DECHETS URBAINS A KINSHASA PAR OBSERVATION LE LONG DE L'AVENUE UNIVERSITE

La gestion des déchets solides, liquides constitue l'un des enjeux majeurs de la ville de Kinshasa aujourd'hui. La question exige d'autant plus l'attention que la somme des contraintes qui ne cesse de croitre, pèse sur l'environnement de la ville. La gestion durable des déchets requiert par conséquent une réflexion globale qui prend en compte l'ensemble des problèmes, des contraintes et des enjeux de l'espace considéré. A travers l'exemple des observations le long de l'avenue université (Rond-point Ngaba jusqu'au boulevard Sendwe), nous tentons comprendre d'aborder d'une manière intégrée la problématique de la gestion des déchets dans la ville de Kinshasa en général et le long de l'avenue université (boulevard Sendwe jusqu'au Rond-point Ngaba). L'analyse systémique cherche de mettre en évidence les effets perturbateurs de la gestion défectueuse de l’espace sur le système de gestion des déchets solides. Grace aux éléments de connaissances et de réponse obtenus, nous proposons un schéma pour la gestion des déchets sur l’avenue université tronçon boulevard Sendwe jusqu’au rond-point Ngaba en se basant sur la promotion des techniques d’assainissement et l’éducation environnementale des riverains. Il s’agit d’aborder le problème dans sa globalité avec une approche systémique qui situe la gestion des déchets le long de l’avenue Université. Cela permet de saisir sous les dimensions intrinsèques et extrinsèques les causes et conséquences de la mauvaise gestion des déchets.

The sheaf representation of residuated lattices

The residuated lattices form one of the most important algebras of fuzzy logics and have been heavily studied by people from various different points of view. Sheaf presentations provide a topological approach to many algebraic structures. In this paper, we study the topological properties of prime spectrum of residuated lattices, and then construct a sheaf space to obtain a sheaf representation for each residuated lattice.

A Hofmann-Mislove theorem for $c$-well-filtered spaces

The Hofmann-Mislove theorem states that in a sober space, the nonempty Scott open filters of its open set lattice correspond bijectively to its compacts saturated sets. In this paper, the concept of $c$-well-filtered spaces is introduced. We show that a retract of a $c$-well-filtered space is $c$-well-filtered and a locally Lindel\"{o}f and $c$-well-filtered $P$-space is countably sober. In particular, we obtain a Hofmann-Mislove theorem for $c$-well-filtered spaces.

The evolution of a study and research path in Statistics

Nous présentons l'organisation d'un premier cours de statistique destiné aux étudiants en gestion d’entreprise, qui comprend un parcours d'étude et de recherche (PER) en tant que proposition d'enseignement basé sur l'enquête. L'article vise à résumer l'évolution du cours, sa conception et les réflexions sur ses différentes composantes, séparément et dans leur ensemble, comme une unité complète. L'analyse prend en compte les différents points de vue sur le cours, celui de l'étudiant, celui de l'enseignant et celui du chercheur, offrant ainsi une perspective critique. Elle inclut également l'évolution conjointe du cours et du PER. Dans le cadre de la théorie anthropologique de la didactique, nous montrons que la conception et la gestion du PER ne peuvent être détachées du cours dans lequel il s’inscrit. Nous montrons comment les composantes du cours nourrissent le PER et comment celle-ci, en retour, fait évoluer le contenu du cours en l'adaptant aux besoins professionnels de l'étudiant. La proposition d'enquête nécessite une approche multidimensionnelle, tant dans sa planification que dans la diffusion de ses résultats dans la recherche et la littérature professionnelle. Par conséquent, notre étude peut contribuer à la recherche en didactique sur les PER, servir de point de départ pour les nouveaux venus à l'enseignement basé sur l'enquête et de point de réflexion pour favoriser les modes de collaboration entre chercheurs en didactique et enseignants universitaires.

Reduction of Kummer surfaces modulo 2 in the non-supersingular case

We obtain necessary and sufficient conditions for the good reduction of Kummer surfaces attached to abelian surfaces with non-supersingular reduction when the residue field is perfect of characteristic 2. In this case, good reduction with an algebraic space model is equivalent to good reduction with a scheme model, which we explicitly construct.

Uniform K-stability of polarized spherical varieties

We express notions of K-stability of polarized spherical varieties in terms of combinatorial data, vastly generalizing the case of toric varieties. We then provide a combinatorial sufficient condition of G-uniform K-stability by studying the corresponding convex geometric problem. Thanks to recent work of Chi Li and a remark by Yuji Odaka, this provides an explicitly checkable sufficient condition of existence of constant scalar curvature Kahler metrics. As a side effect, we show that, on several families of spherical varieties, G-uniform K-stability is equivalent to K-polystability with respect to G-equivariant test configurations for polarizations close to the anticanonical bundle.

Adaptive Merging on Phase Change Memory

Indexing is a well-known database technique used to facilitate data access and speed up query processing. Nevertheless, the construction and modification of indexes are very expensive. In traditional approaches, all records in the database table are equally covered by the index. It is not effective, since some records may be queried very often and some never. To avoid this problem, adaptive merging has been introduced. The key idea is to create index adaptively and incrementally as a side-product of query processing. As a result, the database table is indexed partially depending on the query workload. This paper faces a problem of adaptive merging for phase change memory (PCM). The most important features of this memory type are: limited write endurance and high write latency. As a consequence, adaptive merging should be investigated from the scratch. We solve this problem in two steps. First, we apply several PCM optimization techniques to the traditional adaptive merging approach. We prove that the proposed method (eAM) outperforms a traditional approach by 60%. After that, we invent the framework for adaptive merging (PAM) and a new PCM-optimized index. It further improves the system performance by 20% for databases where search queries interleave with data modifications.

On Insecure Uses of BGN for Privacy Preserving Data Aggregation Protocols

The notion of aggregator oblivious (AO) security for privacy preserving data aggregation was formalized with a specific construction of AO-secure blinding technique over a cyclic group by Shi et al. Some of proposals of data aggregation protocols use the blinding technique of Shi et al. for BGN cryptosystem, an additive homomorphic encryption. Previously, there have been some security analysis on some of BGN based data aggregation protocols in the context of integrity or authenticity of data. Even with such security analysis, the BGN cryptosystem has been a popular building block of privacy preserving data aggregation protocol. In this paper, we study the privacy issues in the blinding technique of Shi et al. used for BGN cryptosystem. We show that the blinding techniques for the BGN cryptosystem used in several protocols are not privacy preserving against the recipient, the decryptor. Our analysis is based on the fact that the BGN cryptosystem uses a pairing e:GxG-->G_T and the existence of the pairing makes the DDH problem on G easy to solve. We also suggest how to prevent such privacy leakage in the blinding technique of Shi et al. used for BGN cryptosystem.

A modular relation involving a generalized digamma function and asymptotics of some integrals containing Ξ(t)

A modular relation of the form $F(\alpha, w)=F(\beta, iw)$, where $i=\sqrt{-1}$ and $\alpha\beta=1$, is obtained. It involves the generalized digamma function $\psi_w(a)$ which was recently studied by the authors in their work on developing the theory of the generalized Hurwitz zeta function $\zeta_w(s, a)$. The limiting case $w\to0$ of this modular relation is a famous result of Ramanujan on page $220$ of the Lost Notebook. We also obtain asymptotic estimate of a general integral involving the Riemann function $\Xi(t)$ as $\alpha\to\infty$. Not only does it give the asymptotic estimate of the integral occurring in our modular relation as a corollary but also some known results.

From Books to Knowledge Graphs

The digital transformation of the scientific publishing industry has led to dramatic improvements in content discoverability and information analytics. Unfortunately, these improvements have not been uniform across research areas. The scientific literature in the arts, humanities and social sciences (AHSS) still lags behind, in part due to the scale of analog backlogs, the persisting importance of national languages, and a publisher ecosystem made of many, small or medium enterprises. We propose a bottom-up approach to support publishers in creating and maintaining their own publication knowledge graphs in the open domain. We do so by releasing a pipeline able to extract structured information from the bibliographies and indexes of AHSS publications, disambiguate, normalize and export it as linked data. We test the proposed pipeline on Brill's Classics collection, and release an implementation in open source for further use and improvement.

Multi-recipient and threshold encryption based on hidden multipliers

Let $S$ be a pool of $s$ parties and Alice be the dealer. In this paper, we propose a scheme that allows the dealer to encrypt messages in such a way that only one authorized coalition of parties (which the dealer chooses depending on the message) can decrypt. At the setup stage, each of the parties involved in the process receives an individual key from the dealer. To decrypt information, an authorized coalition of parties must work together to use their keys. Based on this scheme, we propose a threshold encryption scheme. For a given message $f$ the dealer can choose any threshold $m = m(f).$ More precisely, any set of parties of size at least $m$ can evaluate $f$; any set of size less than $m$ cannot do this. Similarly, the distribution of keys among the included parties can be done in such a way that authorized coalitions of parties will be given the opportunity to put a collective digital signature on any documents. This primitive can be generalized to the dynamic setting, where any user can dynamically join the pool $S$. In this case the new user receives a key from the dealer. Also any user can leave the pool $S$. In both cases, already distributed keys of other users do not change. The main feature of the proposed schemes is that for a given $s$ the keys are distributed once and can be used multiple times. The proposed scheme is based on the idea of hidden multipliers in encryption. As a platform, one can use both multiplicative groups of finite fields and groups of invertible elements of commutative rings, in particular, multiplicative groups of residue rings. We propose two versions of this scheme.

Geodesic Growth of Numbered Graph Products

In this paper, we study geodesic growth of numbered graph products; these are a generalization of right-angled Coxeter groups, defined as graph products of finite cyclic groups. We first define a graph-theoretic condition called link-regularity, as well as a natural equivalence amongst link-regular numbered graphs, and show that numbered graph products associated to link-regular numbered graphs must have the same geodesic growth series. Next, we derive a formula for the geodesic growth of right-angled Coxeter groups associated to link-regular graphs. Finally, we find a system of equations that can be used to solve for the geodesic growth of numbered graph products corresponding to link-regular numbered graphs that contain no triangles and have constant vertex numbering.

The use and impact of auditory stimulation in animals

Music can cause pleasant sensations in humans whereas some noises can cause discomfort. The effects of music and noise have also been somewhat studied in animals, showing different impacts. In this review we aim to illustrate the differences and similarities between animals, in terms of their sensitivity to auditory stimuli (noise or music), by first recalling some generalities about the physical characteristics of sound and the biological bases of hearing. Second, based on the studies reported in this review, we conclude that ambient noise is harmful and/or stressful, and that musical sounds can take many forms with a large range of impacts in animals. Finally, we present two practical examples of the use of music with animals (one in the context of a zoo and the other in cattle breeding) and an example of an experiment designed to understand the impact of music on neonate lambs. These three examples highlight how music can help to improve animal welfare.

Science paysagère au service de l'observatoire scientifique Sociétés-Milieux en appui à la gestion territoriale

Pour mener son action face à une problématique de société, le gestionnaire de territoire doit s’appuyer sur des informations pertinentes dans le temps et l’espace. Les observatoires selon le modèle OSAGE – Observatoire Scientifique en Appui à la GEstion territoriale s'intéressent tout particulièrement aux relations Sociétés-Milieux et peuvent seconder le gestionnaire. Ce travail montre en quoi la méthode OSYPCA d’analyse paysagère et le cadre formel sur lequel elle s’appuie informent sur le milieu et la relation société-milieu et sont utiles aux trois piliers d'un observatoire OSAGE : exigence scientifique, continuité temporelle et ancrage territorial. L’analyse d’une expérience de terrain sur l’île de La Réunion illustre son potentiel à produire une information pertinente même si la connaissance préalable est réduite, à appréhender les dynamiques spatio-temporelles, sans nécessité d’investissements lourds et enfin à mettre en dialogue les disciplines scientifiques entre elles mais aussi les scientifiques avec les acteurs du territoire.

L’adaptation pour une persuasion durable

Persuader est difficile ; persuader sur la durée l’est encore plus. Nous explorons l’adaptation pour apporter de la variété et de la pertinence à la persuasion et ainsi pallier l’usure de l’efficacité des messages persuasifs. Le cas d’étude est TILT, un dispositif persuasif pour la régulation du temps d’usage du smartphone. La persuasion de TILT s’appuie sur le principe d’auto-surveillance. L’expérimentation démontre la pertinence de l’adaptation du message persuasif comme renfort de l’efficacité du principe d’auto-surveillance dans le temps.

Second-order conditions for non-uniformly convex integrands: quadratic growth in $L^1$

We study no-gap second-order optimality conditions for a non-uniformly convex and non-smooth integral functional. The integral functional is extended to the space of measures. The obtained second-order derivatives contain integrals on lower-dimensional manifolds. The proofs utilize the convex pre-conjugate, which is an integral functional on the space of continuous functions. Applications to non-smooth optimal control problems are given.

Analysis of the implicit Euler time-discretization of passive linear descriptor complementarity systems

This article is largely concerned with the time-discretization of descriptor-variable systems coupled to with complementarity constraints. They are named descriptor-variable linear complementarity systems (DVLCS). More speci cally passive DVLCS with minimal state space representation are studied. The Euler implicit discretization of DVLCS is analysed: the one-step non-smooth problem (OSNSP), that is a generalized equation, is shown to be well-posed under some conditions. Then the convergence of the discretized solutions is studied. Several examples illustrate the applicability and the limitations of the developments.

Can a Catholic be Liberal? Roman Catholicism and Liberalism in a Political Economy Perspective (1800–1970)

The philosophy of the Enlightenment and political thought of modernity found tough opposition in the Roman Catholic Church. Liberalism was associated with Free Masons and revolutionary intent. Nonetheless, liberalism and political economy stimulated some theoretical analysis and specific theoretical positions in terms of social philosophy and social economics by the Church. This paper presents an analysis of encyclical letters and other papal documents, as well as the writings of other Catholic scholars, to elaborate on the theoretical points used to contrast liberalism. Compromises, as well as turning points in the evolution of the Catholic position, are investigated. Lastly, the epistemological and historical reasons for the affinity of Roman Catholicism with ethical liberalism and the limits of this similarity are discussed. 1.

Plasticity and ductility of an anisotropic recrystallized AA2198 Al-Cu-Li alloy in T3 and T8 conditions during proportional and non-proportional loading paths: simulations and experiments

The anisotropic material behaviour of a recrystallized AA2198 Al-Cu-Li alloy in T3 and T8 conditions was assessed by proportional loading of uniaxial-tension specimens in rolling (L), transverse (T) and diagonal (D) orientations. The width and longitudinal strains were measured to quantify plastic anisotropy. Notched-tension samples were tested in L and T directions. The material showed weak anisotropy in terms of stress strain curves and a moderate plastic anisotropy, consistent with its texture obtained by EBSD. An anisotropic Bron-Besson type material model was identified using this data base and a micro shear-only (SO) test. The model succeeded in predicting the behaviour of micro specimens for proportional tension-only (TO) loading and non-proportional load path changes including 'shear to tension' (ST) as well as 'tension to shear' (TS) tests. The non-proportional loading was achieved using a newly designed cross shaped sample. It was loaded in one direction, unloaded and subsequently loaded in the orthogonal direction till fracture. The average stretch to fracture of both alloys measured by a four point frame optical extensometer decreased by 29 % and 16 % for T3 and T8 respectively for the 'shear to tension' experiment compared to the proportional TO experiment. The average stretch to fracture of 'tension to shear' tests was reduced by 10 % for 2198T3 and hardly reduced for 2198T8 compared to the stretch to fracture of the SO tests, but subject to strong scatter. FE simulations showed local accumulated strain to fracture values that were similar for all loading histories for the T8 condition (0.73 − 0.84). Lower strain to fracture values were found in T3 condition (0.45 − 0.73), despite the enhanced macroscopic ductility in tension. This was attributed to larger less localized plastic zones, especially for the ST test. The ductility scatter was attributed to necking and damage development in tension that can affect strain localization, associated fracture path and ductility, as observed by DIC and fractography.

Thermal and energy analysis of DMTA tests

This paper investigates the suitability of the isothermal linear viscoelastic framework to describe the behavior of polymers observed during DMTA tests. A good interpretation of these tests is important because, in practice, they are used to construct master curves using the time-temperature superposition principle at small strain. These curves are then considered to predict the material behavior under experimentally unreachable thermal and/or loading frequency conditions. Currently, the DMTA protocol neglects the temperature variations induced by the deformation of polymers. We wonder if these temperature variations can have an influence on the measurement of dynamic moduli. To answer this question, quantitative infrared techniques were developed and used to assess small temperature variations of samples undergoing cyclic loadings during mechanical spectrometry tests. Thermal and mechanical data were used to quantify the viscous dissipated and the thermoelastic coupling energies that can be both associated with the hysteretic stress-strain response of polymers. Energy balances were then performed to quantify the relative importance of dissipative and thermoelastic coupling heat sources. From the energy standpoint, it is found that the thermoelastic energy rate was dozens of times higher than the dissipation. Especially at low frequencies, thermoelastic effects can have a greater influence on the loss modulus value than viscosity.

Optimal controller synthesis for timed systems

Weighted timed games are zero-sum games played by two players on a timed automaton equipped with weights, where one player wants to minimise the cumulative weight while reaching a target. Used in a reactive synthesis perspective, this quantitative extension of timed games allows one to measure the quality of controllers in real-time systems. Weighted timed games are notoriously difficult and quickly undecidable, even when restricted to non-negative weights. For non-negative weights, the largest class that can be analysed has been introduced by Bouyer, Jaziri and Markey in 2015. Though the value problem is undecidable, the authors show how to approximate the value by considering regions with a refined granularity. In this work, we extend this class to incorporate negative weights, allowing one to model energy for instance, and prove that the value can still be approximated, with the same complexity. A small restriction also allows us to obtain a class of decidable weighted timed games with negative weights and an arbitrary number of clocks. In addition, we show that a symbolic algorithm, relying on the paradigm of value iteration, can be used as an approximation/computation schema over these classes. We also consider the special case of untimed weighted games, where the same fragments are solvable in polynomial time: this contrasts with the pseudo-polynomial complexity, known so far, for weighted games without restrictions.

Modularity and Combination of Associative Commutative Congruence Closure Algorithms enriched with Semantic Properties

Algorithms for computing congruence closure of ground equations over uninterpreted symbols and interpreted symbols satisfying associativity and commutativity (AC) properties are proposed. The algorithms are based on a framework for computing a congruence closure by abstracting nonflat terms by constants as proposed first in Kapur's congruence closure algorithm (RTA97). The framework is general, flexible, and has been extended also to develop congruence closure algorithms for the cases when associative-commutative function symbols can have additional properties including idempotency, nilpotency, identities, cancellativity and group properties as well as their various combinations. Algorithms are modular; their correctness and termination proofs are simple, exploiting modularity. Unlike earlier algorithms, the proposed algorithms neither rely on complex AC compatible well-founded orderings on nonvariable terms nor need to use the associative-commutative unification and extension rules in completion for generating canonical rewrite systems for congruence closures. They are particularly suited for integrating into the Satisfiability modulo Theories (SMT) solvers. A new way to view Groebner basis algorithm for polynomial ideals with integer coefficients as a combination of the congruence closures over the AC symbol * with the identity 1 and the congruence closure over an Abelian group with + is outlined.

On the long time behaviour of single stochastic Hodgkin-Huxley neurons with constant signal, and a construction of circuits of interacting neurons showing self-organized rhythmic oscillations

The stochastic Hodgkin-Huxley neurons considered in this paper replace time-constant deterministic input $a dt$ of the classical deterministic model by increments $\vartheta dt + dX_t$ of a stochastic process: $X$ is Ornstein-Uhlenbeck with volatility $\sigma>0$ and backdriving force $\tau>0$, and we call $\vartheta>0$ the signal. We have ergodicity and strong laws of large numbers for various functionals of the process, and characterize 'quiet behaviour' and 'regular spiking' as events whose probability depends on the parameters $(\tau,\sigma)$ and on the signal $\vartheta$. The notions of quiet behaviour and regular spiking allow for a construction of circuits of interacting stochastic Hodgkin-Huxley neurons, combining excitation with inhibition according to a bloc structure along the circuit, on which self-organized rhythmic oscillations can be observed.

Theoretical study of the emergence of periodic solutions for the inhibitory NNLIF neuron model with synaptic delay

Among other models aimed at understanding self-sustained oscillations in neural networks, the NNLIF model with synaptic delay was developed almost twenty years ago to model fast global oscillations in networks of weakly firing inhibitory neurons. Periodic solutions were numerically observed in this model, but despite its intensive study by researchers in PDEs and probability, there is up-to-date no analytical result on this topic. In this article, we propose to approximate formally these solutions by a Gaussian wave whose periodic movement is described by an associate delay differential equation (DDE). We prove the existence of a periodic solution for this DDE and we give a rigorous asymptotic result on these solutions when the connectivity parameter $b$ goes to $-\infty$. Lastly, we provide heuristic and numerical evidence of the validity of our approximation.

Les parties prenantes de la gouvernance du système olympique

Cet article retrace l'apparition chronologique des parties prenantes qui mettent sur pied, tous les quatre ans, les Jeux olympiques modernes. Toutes ces parties prenantes forment aujourd'hui un système (olympique) dont la gouvernance s'est considérablement complexifiée au fil des olympiades et qui ne saurait être aujourd'hui uniquement hiérarchique (sous l'égide du Comité international olympique ou sous le contrôle des Etats) ou gouverné par le seul marché (représentés par les sponsors et les diffuseurs). L'article suggère une gouvernance collaborative qui intègre toutes les parties prenantes et notamment celles qui ont récemment pris beaucoup d'importance : les athlètes d'élite, les groupes citoyens et les ordres judiciaires, ainsi que les gouvernements locaux, régionaux et nationaux qui voient leurs rôles traditionnels de plus en plus renforcés dans le système olympique du XXIe siècle. Le Comité international olympique (CIO) a été créé en 1894 à l'issue d'un congrès organisé à Paris pour le rétablissement des Jeux olympiques. Depuis, il a fait en sorte que ces Jeux soient organisés tous les quatre ans dans une grande ville d'Europe ou des Etats-Unis, puis du monde entier (sauf pendant les deux guerres mondiales, en 1916, 1940 et 1944). La seule exception à ce rythme quadriennal est fournie par les Jeux prévus à Tokyo pour l'été 2020 et qui ont été reportés à l'été 2021 (tout en gardant le nom de « Tokyo 2020 ») à cause de la pandémie de Covid-19 qui se déclara au début 2020. Dès ses débuts, le CIO fut rejoint par d'autres organisations sportives qui contribuent à l'organisation des Jeux olympiques (d'été) (ainsi que des Jeux d'hiver depuis 1924 et des Jeux de la jeunesse depuis 2010) et qui sont aujourd'hui les parties prenantes d'un véritable système inter organisationnel en réseau qui s'est considérablement complexifié au fil du temps.

Les modèles économiques des associations sportives : le cas des clubs de handball du nord de la France

La fédération française de handball a mis au cœur de son projet stratégique la volonté de voir ses clubs diversifier leurs ressources financières et multiplier les offres de pratique (santé, loisir…) pour rester attractif dans un contexte sportif en mutation. Afin d’accompagner ce processus, cette recherche s’intéresse aux modèles économiques des clubs de handball dans l’objectif de les catégoriser et d’identifier des leviers de développement. Différentes méthodes statistiques ont été appliquées pour y parvenir. Une analyse en composantes principales (ACP) et une classification K-means permettent de proposer une double taxonomie des clubs : de leurs modèles économiques et de leur niveau de professionnalisation. Ces méthodes sont appliquées aux clubs du Comité Nord (59 clubs) qui ont été sollicités par l’envoi d’un questionnaire. La grille de lecture créée permet de caractériser la situation actuelle des clubs de handball français et d’identifier différentes opportunités et menaces pour chacune des catégories identifiées.

The solutions of classical and nonlocal nonlinear Schrödinger equations with nonzero backgrounds: Bilinearisation and reduction approach

In this paper we develop a bilinearisation-reduction approach to derive solutions to the classical and nonlocal nonlinear Schr\"{o}dinger (NLS) equations with nonzero backgrounds. We start from the second order Ablowitz-Kaup-Newell-Segur coupled equations as an unreduced system. With a pair of solutions $(q_0,r_0)$ we bilinearize the unreduced system and obtain solutions in terms of quasi double Wronskians. Then we implement reductions by introducing constraints on the column vectors of the Wronskians and finally obtain solutions to the reduced equations, including the classical NLS equation and the nonlocal NLS equations with reverse-space, reverse-time and reverse-space-time, respectively. With a set of plane wave solution $(q_0,r_0)$ as a background solution, we present explicit formulae for these column vectors. As examples, we analyze and illustrate solutions to the focusing NLS equation and the reverse-space nonlocal NLS equation. In particular, we present formulae for the rouge waves of arbitrary order for the focusing NLS equation.

Full-deautonomisation of a class of second-order mappings in ancillary form

We present an application of the full-deautonomisation method to a class of secondorder mappings which, using an ancillary variable, can be cast into a form that greatly facilitates the study of their singularities. The ancillary approach was originally introduced to make it possible to construct discrete Painlevé equations associated with the affine Weyl group E (1) 8 by deautonomising a QRT mapping. The full-deautonomisation method has been shown to offer a practical technique for calculating the exact dynamical degree of a mapping, whereby allowing the detection of discrete integrability using only singularity analysis. We study the confinement property for a given singularity, for a wide class of mappings that includes the autonomous limit of the standard additive Painlevé equation with E (1) 8 symmetry. This leads to a class of non-autonomous mappings, which can be integrable or not, for which we obtain their exact dynamical degrees. The case of a non-confining singularity is also analysed and again we obtain the corresponding dynamical degrees.

D’un rêve d'universalité fonctionnelle au libéralisme linguistique : standardisation de la langue tchèque moderne et controverse des années 1990 et 2000

Au cours du XIXe et du début du XXe siècle, les philologues tchèques travaillèrent activement sur la variante cultivée de la langue. Dans les années 1930, le Cercle linguistique de Prague proposa une théorie de la langue standard et de culture de la langue, basée sur le critère fonctionnel, qui devint la base de toute réflexion sur la langue standard tchèque jusqu’à présent. Dans les années 1990 et 2000, certains bohêmistes considérèrent le tchèque standard ainsi conçu comme un code imposé, en conflit avec les usages quotidiens, et cherchèrent de nouvelles solutions.

Jeunes et dispositifs participatifs au Maroc Usages du conseil des jeunes de la ville de Ouarzazate

Cet article porte sur un dispositif participatif mis en place au Maroc : les conseils des jeunes. Ceuxci ont pour objectif d’associer la jeunesse marocaine à l’élaboration des politiques publiques locales. Il vise à interroger les usages différenciés de ce dispositif par les acteurs de l’action publique locale. Comment les conseils des jeunes transforment les jeunes qui y participent, mais également comment ces derniers parviennentils à influencer l’action publique locale ? Telle est la question à laquelle nous voudrions présenter des éléments de réponse dans le cadre de cette recherche. La question du lien entre jeunes et politiques publiques est liée à l’usage des dispositifs publics par cette catégorie sociale. Dans ce sens il est important ici de chercher à comprendre comment des acteurs qui contestent ouvertement un ou plusieurs aspects de l’intervention publique finissent par devenir acteurs de cette même politique publique. L’hypothèse à démontrer dans ce cadre, à partir de l’expérience du conseil des jeunes de la ville de Ouarzazate, est que les jeunes qui contestent une stratégie d’une politique publique locale finissent par accepter cettestratégie suite à leur entrée dans l’action publique locale. Cette recherche s’appuie sur le recueil des données qualitatives issues d’entretiens semidirectifs réalisés entre mai 2017 et mai 2019 auprès des membres de la coordination nationale des conseils des jeunes, des jeunes mobilisésautour du conseil des jeunes et des élus locaux dans une ville ayant une situation socioéconomique différente des grandes métropoles marocaines: Ouarzazate. Les enquêtes de terrain montrent que les jeunes organisés autour d’un dispositif qualifié de participatif sont capables d’assurer leur entrée dans l’action publique locale, mais cela engendre des effets inverses à leur position de départ. Ce dispositif participatif ne permet que de rapprocher les jeunes des représentants des pouvoirs publics et de modifier, en conséquence, leurs revendications. Le dispositif du conseil des jeunes contribue ainsi à approuver le discours officiel par des jeunes qui contestaient auparavant une action publique locale.

La stylisation dans les traductions du Nouveau Testament en langue vernaculaire macédonienne moderne, au XIXe siècle

L’Évangéliaire de Konikovo (EK), l’Évangéliaire de Kulakia (EKu) et l’Évangéliaire de Boboščica (EB) sont les premières traductions sérieuses duNouveau Testament en langue vernaculaire macédonienne du XIXe siècle. Ils sont tous écrits en alphabet grec. Cet article présente les exemples les plus spécifiques des textes montrant une tendance à la stylisation par élargissement de la base dialectale et/ou par élévation du style. De toutes les traductions des évangiles en langue vernaculaire macédonienne de Macédoine du sud du XIXe siècle ayant été analysées, on peut conclure que le texte le plus stylisé et en même temps le plus ancien est celui de l’EK (1852), et surtout sa deuxième main. Les démarches de stylisation sont moins perceptibles dans le texte de l’EKu (1860) et encore moins perceptibles dans celui de l’EB (1880). On peut dire que les traductions analysées, mais aussi les autres traductions du Nouveau Testament en langue vernaculaire macédonienne de Macédoine du sud des XVIIIe et XIXe siècles ouvrent, plus ou moins, une voie vers la formation d’une langue biblique, voie aboutissant aux traductions de la Bible en macédonien standard contemporain en 1976, 2003 et 2007.
