A personal re-membering of Michael Field: a critical dis-membering of Works and Days
No full text‘Michael Field’ was the pseudonym of two women, the aunt and niece Katharine Bradley and Edith Cooper, who lived and wrote together during the turn of the twentieth century. Recent years has seen an increased critical interest in their poetry, with particular attention paid to the dynamics of their pen-name within gender politics of the period. However, little attention has been paid to their most impressive creation – a twenty-eight volume journal of their ‘Works and Days’ as Michael Field. By offering a close-reading of their strategies of self-representation, this thesis investigates the journal as a site where the women explored and performed their engagement with identity politics, and charted their own response to changing epistemologies of the subject during the nineteenth century. I situate their ideas of the autobiographical subject against a trajectory of self-representation that links the theory and practice of Thomas Carlyle’s Sartor Resartus to that of Roland Barthes by Roland Barthes. Using these texts to illuminate the ideas under investigation in Works and Days, I explore how the Michael Field diaries contribute an important interjection into both nineteenth century epistemologies of the subject and theories of autobiographical writing
Optimization of Alumina Slurry for Oxide-Oxide Ceramic Composites Manufactured by Injection Molding
No full textThis paper focuses on the rheological study of an alumina suspension intended for the manufacturing of oxide-oxide composites by flexible injection. Given the production constraints, it is required to have stable suspension with low viscosity and a Newtonian behavior. This is achieved with a concentration of nitric acid between 0.08 wt% and 0.2 wt% and amount of 3 wt% of PVA binder. The maximum loading of the suspension of 47 vol% suggests that there is no structure development within the suspension with optimized concentration of acid and PVA

Barthes, Bakhtin, Structuralism: A Reassessment
No full textPhDThe thesis is a comparative analysis of the shared ideas and concerns in the works of
Mikhail Bakhtin and Roland Barthes from the point of view of differences between
French and Slavic literary structuralisms. Its background argument is that the
structuralism developed in the later works of the Russian Formalists and by Prague
Structuralists and Soviet Semioticians is more historically and socially oriented than its
French version, defining the structure of a literary work as a system of all of its
elements and effects (even those that take us outside of the text, like literary tradition
and historical and political circumstances). In this sense, Bakhtin can be seen as a part
of the Slavic structuralist tradition (and not opposed to it as is often claimed), and
Barthes (seen throughout his career) is on the whole perhaps closer to the Slavic
structuralism than he is to the French.
The particular problems discussed are those of the relationship between
literature and ideology, the notions of intertextuality, heteroglossia, dialogism and
polyphony and the differences between them, and the role of the author.
Barthes and Bakhtin shared a lifelong interest in the role of ideology in literature
and the influence of authoritarian language or myth on culture in general and the literary
text in particular. They looked for ways in which the deadening effect of the
mythological (epic, monological) thought and word can be counteracted through
literature, and different versions of what Kristeva termed 'intertextuality' played an
important part in their treatment of the subject. They also both discussed the role of the
author and their voice in the literary text, and the question of their power over the text,
its characters (Bakhtin) and the reader (Barthes).
The main thread of Barthes and Bakhtin's thought focuses on the problem of
counteracting authoritarian language through literature, and the solutions they proposed
can fruitfully be seen in the light of Slavic structuralism's notions of literary structure
Amortissement élevé et vibration non-linéaire de poutres sandwichs avec un matériau d'âme à base de fibres enchevêtrées-réticulées
No full textInternational audienceThis article investigates the use of a recently developed fibrous core material to increase vibration damping in sandwich beams. The entangled cross-linked fibre (ECF) material is made of short carbon fibres cross-linked with epoxy resin. Dry friction between fibres provides energy dissipation when the material is deformed. Previous measurements on the material are post-processed to provide a simplified viscoelastic description of the material, for an easier interpretation of subsequent structural testings. Two sandwich beams are compared with reference honeycomb beams: a sandwich beam with an ECF core, and a hybrid beam with a honeycomb core and an ECF insert. Steady-state tests are performed on both types of beams to obtain their frequency responses for different excitation levels, and the corresponding apparent loss factors are computed. The beam with a full ECF core shows an apparent loss factor more than ten times higher than the reference honeycomb beam. The hybrid sandwich beam provides an apparent loss factor four times higher than the reference honeycomb beam. All beams exhibit nonlinear softening responses consistent with a dry friction phenomenon in the material: the resonance frequencies decrease with increasing excitation amplitude, and damping increases then decreases again at very high amplitudes while remaining largely superior to that of the honeycomb beams. Transient impact testings are also presented for a qualitative comparison of the ECF and reference beams, and the ECF beams lead to shorter decay times compared to the reference beams.Cet article étudie l'utilisation d'un matériau d'âme récent pour augmenter l'amortissement vibratoire de poutres sandwichs. Le matériau à base de fibres enchevêtrées-réticulées est constitué de courtes fibres de carbone réticulées avec de la résine époxy. Le frottement sec entre les fibres conduit à une dissipation d'énergie lorsque le matériau est déformé. Des mesures antérieures sur le matériau sont post-traitées pour fournir une description viscoélastique simplifiée du matériau, afin de permettre une interprétation plus simple des essais structuraux présentés par la suite. Deux poutres sandwichs sont comparées avec des poutres de référence ayant une âme en nid d'abeille : une poutre avec une âme enchevêtrée-réticulée, et une poutre hybride avec une âme en nid d'abelle et un insert enchevêtré-réticulé. Des essais en régime établi sont réalisés pour les deux types de poutres pour obtenir leur réponse fréquentielle pour différents niveaux d'excitation, et le facteur de perte apparent est calculé. La poutre ayant une âme enchevêtrée-réticulée sur toute la longueur montre un facteur de perte apparent plus de dix fois plus élevé que la poutre de référence à âme en nid d'abeille. La poutre sandwich hybride conduit à un facteur de perte apparent quatre fois plus élevé que la poutre de référence à âme en nid d'abeille. Toutes les poutres conduisent à une réponse non-linéaire assouplissante cohérente avec le phénomène de frottement sec dans le matériau : les fréquences de résonance décroissent lorsque l'amplitude d'exctation croît, et l'amortissement croît puis décroît à nouveau à très haute amplitude, tout en restant largement supérieur à celui des poutres à âme en nid d'abeille. Des essais d'impact transitoires sont également présentés pour une comparaison qualitative des poutres enchevêtrées-réticulées avec les poutres de référence, et les poutres enchevêtrées-réticulées conduisent à un temps de décroissance plus court que celui des poutres de référence
