The Slow Erosion Limit in a Model of Granular Flow
No full textWe study a 2 × 2 system of balance laws that describes the evolution of a granular material (avalanche) flowing downhill. The original model was proposed by Hadeler and Kuttler (Granul Matter 2:9–18, 1999). The Cauchy problem for this system has been studied by the authors in recent papers (Amadori and Shen in Commun Partial Differ Equ 34:1003–1040, 2009; Shen in J Math Anal Appl 339:828–838, 2008). In this paper, we first consider an initial-boundary value prob- lem. The boundary condition is given by the flow of the incoming material. For this problem we prove the global existence of BV solutions for a suitable class of data, with bounded but possibly large total variations. We then study the “slow erosion (or deposition) limit”. We show that, if the thickness of the moving layer remains small, then the profile of the standing layer depends only on the total mass of the avalanche flowing downhill, not on the time-law describing the rate at which the material slides down. More precisely, in the limit as the thickness of the moving layer tends to zero, the slope of the mountain is provided by an entropy solution to a scalar integro-differential conservation law

Implied Author, Overall Consideration, and Subtext of "Desiree's Baby"
No full textThis essay explores how to infer from a text the image of the implied author. It examines Kate Chopin's "Desiree's Baby" (1893), which has been widely regarded as an indictment of racism but which an "overall consideration" of the implied author's choices will lead us to see as a racist text. Through the interaction of various details in the text, the implied author suggests three racist dichotomies: (1) white characters' nondiscrimination versus black characters' discrimination, (2) positive slavery under white masters versus negative slavery under a black master, and (3) superior whites versus inferior blacks. This implied racist stance reflects the historical context of Chopin's personal experiences, but it contrasts with the quite different racial stances of the implied authors of some other Chopin narratives with different thematic designs. The complexity of the narratives under the name "Kate Chopin" offers an opportunity not only to gain a better understanding of the concept of implied author but also to clarify the relations (connections as well as disparities) among textual, intertextual, and extratextual evidence in literary interpretation in general.LiteratureA&HCI4ARTICLE2285-3113
Chinese users’ preference for web browser icons
No full textThis paper compares the perspicacity, appropriateness and preference of web browser icons from leading software providers with those of a culture-specific design. The history and future direction of web browsers is outlined, together with the implications for the future growth of Chinese internet users. China, with its rapidly expanding young netizens has now overtaken the USA in terms of the number of internet users (253 million) and we predict it will reach saturation (?70% internet penetration rate) by 2012. If correct, this will have a dramatic effect on the use of English as the ‘Lingua Franca’ of the Internet. This online study was conducted in Taiwan and involved 103 participants (mean age 21 years), who were given three sets of web browser icons to review, namely Microsoft Internet Explorer 7.0, Macintosh Safari 3.0, and culturally specific icons created using the Culture-Centred Design methodology. The findings of the study show that all three sets have generally high recognition rates, but that some icon functions (e.g. Go/Visit and Favourite) in all three sets have poor recognition rates and are considered inappropriate. Furthermore, some significant differences were found when we analysed the level of user experience amongst several icon

“Shen Congwen Literary Thought and the Development of Chinese Modern Literature”
No full textThe study presents a reflection on the Chinese literature at the beginning of the twentieth century prompted by an examination of the non-fiction works written by Shen Congwen. This author wrote between the 1920s and 1940s and was driven by his conviction that literature would have changed China’s future. He concentrated on issues such as originality, creativity and imagination, without which he felt literary works could not be produced, and encouraged young authors to carry out research on style and experimentation in order to create a new body of literature and a new poetical language in a particularly delicate moment of Chinese history influenced by an escalation of Marxist aesthetic theories
Shen Gua (1031-1095) et les sciences
No full textSummary. — Shen Gua (1031-1095) is the author of a famous collection of notes which treat a great variety of subjects. Most modern historians of Chinese science consider him to have been the greatest Chinese « scientist » of the Middle Ages. However, before the twentieth century, Shen Gua was regarded, even in China, as an outstanding literary scholar, not a man of science. What is the significance of such a radical change of viewpoint, and what is the true nature of Shen Gua's works ? We try to outline answers to such questions by examining both the historio graphical background of Chinese science and Shen Gua's works as they appear in their historical context.Résumé. — Shen Gua (1031-1095) est l'auteur d'un célèbre recueil de notes abordant des sujets extrêmement variés. La plupart des historiens actuels des sciences chinoises le considèrent comme le plus grand « homme de science » du Moyen Age. Pourtant^ avant le xxe siècle, en Chine même, on rattachait généralement Shen Gua à la littérature plutôt qu'à la science. Quelle est la signification d'un changement de point de vue aussi radical et quelle est la véritable nature de l'œuvre de Shen Gua ? Nous tentons d'esquisser les réponses à de telles questions en examinant à la fois l'arrière-plan historiographique des sciences chinoises et l'œuvre de Shen Gua telle qu'elle se présente dans son contexte historique.Brenier Joël, Dieny Colette, Martzloff Jean Claude, De Wieclawik Wladislaw.

Optimal resonator damping for wave propagation control in mechanical metamaterials
No full textA novel approach to the optimal damping of linearly damped resonators embedded in metamaterial systems is proposed with the aim of minimizing the metamaterials’ response when the external excitation frequency lies within one of the bandgaps. The equation governing wave propagation in the metamaterial system is obtained via a Galerkin projection combined with the quasi-periodicity ansatz of the Floquet–Bloch theorem. It is shown that an optimality criterion can be obtained for the resonator damping for any excitation frequency by extending the Den Hartog theory of fixed points in the frequency response functions. A numerical example of a honeycomb metamaterial is discussed to show how the proposed method works in a practical application. A full numerical optimization is carried out to study the quality factor of the metamaterials’ response with respect to the resonator damping ratio while proving its effectiveness. © 2023 Elsevier Lt
