High-order WENO scheme for Polymerization-type equations

Polymerization of proteins is a biochimical process involved in different diseases. Mathematically, it is generally modeled by aggregation-fragmentation-type equations. In this paper we consider a general polymerization model and propose a high-order numerical scheme to investigate the behavior of the solution. An important property of the equation is the mass conservation. The fifth-order WENO scheme is built to preserve the total mass of proteins along time

The sub-stance of Joyce's gramma(r) and language(s) at the Wake

The aims of the thesis are to show how "grammar,' etymological sense of "art or technique of the letter, to the composition and narrative-thematic structuring of Finnegans Wake as well as to illustrate its treatment in several languages used in Finnegans Wake. The first section will define the critical perspectives, starting with a survey of the elaboration of the Wakean poetics of is crucial language(s). We shall then summarise the manuscript approach in Wakean scholarship before attempting to redefine the notion of "theme" and "thematic criticism" from this genetic angle. This will include a brief discussion of the reflexive, metafictional dimension of Joyce’s work. The second section will consider some significant aspects of how language(s) and meaning operate in the text. We shall assess the structural and formal implications of "metaphor" for the language, narrative, themes and composition of the Wake, and then focus on various fictional treatments of the theme of origin(s} in language: Vichian and Joussean theories, Dante, the myths of Babel, Pentecost, and "translation" as another figure of "metaphor." The third part will examine some derivations to which "grammar" lends itself narratively and linguistically, opening with the relevance of Poe’s "The Purloined Letter." It will then concentrate on its narrative and structural function as a cohesive link between chapters and finally deal with the theme of female identity and sexual grammar. The fourth part will analyse more specifically some thematic associations between grammar and languages: Italian, Dante, music, and italics; "grammatical," sexual perversions of Irish and its relation to English and Anglo-Irish; Joyce’s use of Uralic languages. A brief conclusion will bring together some "thematic families" of languages / characters seen on the way before coming to a full stop on the Wake’s thematicisation of punctuation

Semantic query languages for knowledge-based web services in a construction context

Since the early 2000s, different frameworks were set up to enable web-based collaboration in building projects. Unfortunately, none of these initiatives was granted a long life. Recently, however, the use of web technologies in the building industry has been gaining momentum again, considered some promising technologies for reaching a more interoperable BIM practice. Specifically, this relates to (1) Linked Data and Semantic Web technologies, and (2) cloud-based applications. In order to combine these into a network of interlinked applications and datastores, an agreed-upon mechanism for automatic communication and data retrieval needs to be used. Apart from the W3C standard SPARQL, often considered too high a threshold for developers to implement, there are some recent GraphQL-based solutions that simplify the querying process and its implementation into web services. In this paper, we review two recent open source technologies based on GraphQL, that enable to query Linked Data on the web: GraphQL-LD and HyperGraphQL

Indices de perceptibilité et de différenciabilité des timbres vocaliques : la variabilité [e] - [ε] en français

Devant les incertitudes de la discrimination auditive, en particulier pour la perception du « double timbre » des voyelles en français, on a tenté d’établir des critères objectifs à l’aide de l’analyse acoustique. On a établi deux critères d’analyse formantiques : l’indice de perceptibilité (représentant l’écart acoustique entre F1 et F2) et l’indice de différenciabilité (écart entre les indices de perceptibilité de deux timbres différents). Ils ont permis d’établir une échelle des valeurs acoustiques des timbres du E fermé et ouvert en position accentuée, dans l’idiolecte d’un locuteur français.L’étude perceptive a montré que l’indice de perceptibilité joue un rôle essentiel; donc le fait que le spectre vocalique est diffus ou compact — plutôt que la hauteur absolue des formants. Elle montre également que les timbres ont des réalisations acoustiques extrêmement fluctuantes. Cette variabilité acoustique contraste ici avec le système de réalisations phonétiques nettement catégorisé du locuteur examiné.Les indices établis pourraient probablement être appliqués de manière plus efficace et plus nette à la détermination des timbres inaccentués.Due to the uncertainty of aural discrimination, particularly for the perception of the so called "double timbre" of French vowels, an attempt has been made to establish objective criteria, with the help of acoustical analysis. Two criteria of formant analysis were established: the perceptibility index (representing the acoustical difference between F1 and F2) and the distinguishability index (difference between two perceptibility indexes of two different timbres). We used them in order to establish a scale of acoustical values of timbres for open and closed E in stressed position, in a French speaker's idiolect.A perceptual study showed that the perceptibility index plays an important role and is the most relevant factor for the sake of perception, and that the compactness or diffuseness of the acoustical spectrum is more important than the absolute fixed formant height. This study also shows that timbres have extremely variable acoustic actualisations. This acoustic variability is in contrast here with a rather strict system of phonic realizations, sharply categorized in our speaker's speech.The two indexes that we established here could probably be used in a more efficient and evident way to determine the timbres of unstressed vowels
