The revision of an orientalist to a reoriented image : Arab women in The Algerian Quartet by Assia Djebar
No full textCette thèse porte sur l’œuvre d’Assia Djebar qui est une des plus grandes représentantes de la littérature maghrébine de langue française. Elle met à profit les nombreux travaux occidentaux déjà menés sur cette œuvre en les infléchissant et en les prolongeant par une approche personnelle qui s’attache à montrer comment l’écriture de cette écrivaine postcoloniale a contribué à renouveler la représentation des femmes arabes.La première partie fait d’abord le point sur la constitution de stéréotypes popularisés par les représentations orientalistes qui réduisaient les femmes orientales au statut d’objet esthétique et fantasmatique puis sur les apports des théories (théorie postcoloniale ; courants féministes) qui ont permis la déconstruction de l’approche orientaliste et de son idéologie sous-jacente. La deuxième partie montre comment l’écriture d’Assia Djebar s’inscrit dans cette perspective féministe postcoloniale. Ses récits donnent à de nombreux personnages de femmes algériennes des sensibilités, des modalités expressives, des rôles historiques et sociaux qui en font des sujets pleins et complexes. La troisième partie se concentre sur l’autoportrait de l’écrivaine qui s’affirme en tant que femme d’origine arabo-berbère assumant une hybridité culturelle et identitaire qui se traduit par les innovations génériques, poétiques et linguistiques de ses récits.This thesis focuses on the work of Assis Djebar, one of the greatest representatives of Francophone Maghreb literature. It draws on numerous works on this literature already published by modifying their approach and adding a personal perspective to show how this postcolonial writer renews the representation of Arab women.The first part of this study shows how the popular stereotypes invented by Orientalists reduced women to fantasmatic and aesthetic objects but the contribution of certain theories (postcolonial and feminist) have allowed the deconstruction of this Orientalism and its underlying ideology. The second part shows how Assia Djebar’s writing fits into the postcolonial feminist perspective. The author attributes many Algerian women characters with sensibilities, expressive modes, social and historical roles that make them fully-rounded and complex people. The third part focuses on the self-portrait of the author as a woman of Arab-Berber origin who recognises herself as a cultural and identity hybrid, reflected in the generic, poetic and linguistic innovations of her work

No full textCoordination Mechanism Between Electric Vehicles and Air Conditioning Loads Based on Price Guidance
No full textUnder China’s dual carbon goals, the surging summer demand for air conditioning (AC) has widen the power grid’s peak-to-valley difference, posing challenges to conventional supply-side solutions. To address this issue, effective demand-side coordination is essential. However, existing demand response schemes typically optimize single resources in isolation and overlook the dynamic evolution of user participation. This study proposes a price-guided coordination mechanism integrating vehicle-to-grid (V2G) and AC loads to establish a closed-loop value chain among the grid, aggregators, and users. A bi-level optimization framework is developed to balance the interests of these stakeholders. The model incorporates a V2G discharging willingness component that considers user psychology and battery degradation, as well as an AC response model reflecting thermal comfort. Simulation results demonstrate that the proposed mechanism effectively mitigates peak loads and narrows the peak-to-valley difference while enhancing off-peak electricity consumption. It accommodates the spatiotemporal and user-type heterogeneity of response behaviors, yielding notable economic gains for all participants. This research validates a comprehensive strategy for improving grid flexibility, protecting stakeholder interests, and optimizing user engagement, offering both theoretical insight and practical guidance for diversified resource integration
Experimental Study on Flow Condensation Heat Transfer of R410A inside Horizontal Internal Ribbed Tube
No full textIn the study, the flow condensation heat transfer characteristics of R410A inside a horizontal internal ribbed tube was experimentally investigated, and the influence of hydraulic conditions and structural parameters of a test tube on the refrigerant surface coefficient of heat transfer and pressure drop inside the tube was analyzed. The experimental results indicate that the surface coefficient of heat transfer and pressure drop increase with the increase in the mass velocity and the decrease in the condensation temperature. However, the surface coefficient of heat transfer decreases with the increase in Re of the water flow, and the pressure drop is slightly affected by the Re of the water flow. The surface coefficient of heat transfer under a unit pressure drop was used to evaluate the comprehensive performance of the heat exchanger. The results reveal that it decreases with the increase in the mass velocity, and increases with the increase in the condensation temperature. The experimental data was also compared with the prediction of some classical correlations. For the smooth tube, the correlations obtained by Shah and Thome et al. overestimate the experimental data, and the Thome et al. correlation exhibits the highest prediction accuracy although the correlation obtained by Akers et al. underestimates the experimental data. With respect to the internal ribbed tube, the Cavallini et al. correlation exhibits the highest prediction accuracy, and correlations obtained by Koyama et al. and Miyara et al. underestimate the experimental data
Improvement of Computational Correlation of R134a Flow Condensation Heat Transfer Characteristics inside a Micro-fin Tube
No full textIn this study, the surface heat transfer coefficient was selected as the evaluation index and the two-phase flow condensation heat transfer characteristics of R134a inside a horizontal micro-fin tube with 6.35 mm outer diameter were studied. The effects of the test conditions and structural parameters of the micro-fin tube on the surface heat transfer coefficient were analyzed. Correlations of Cavallini et al., Miyara et al., and Oliver et al. were also applied to predict the surface heat transfer coefficient inside the micro-fin tube. We found that the correlation of Cavallini et al. was the most effective at predicting the heat transfer characteristics, where the average and mean deviations of predicted and experimental values were ﹣21.47% and 21.94%, respectively. Although the average and mean deviations of the predicted and experimental values of the correlation of Miyara et al. were 16.21% and 30.65%, respectively, the margin of deviation was ﹣47.12% to 82.32%, which indicates that a greater deviation still exists between the predicted and experimental values under certain conditions for the correlation of Miyara et al.. The predictive ability of the correlation of Oliver et al. was the worst of the three correlations, where the average deviation of the predicted and experimental values was ﹣54.93%. The correlation of Oliver et al. was thus modified based on the experimental data, and its predictive ability was improved greatly, where the average and mean deviations of the predicted and experimental values were ﹣2.37% and 10.77%, respectively
Visualizing and Understanding Shrinking Cities and Towns (SCT) Research: A Network Analysis
No full textThe world is undergoing an unprecedented trend of fast urbanization, which causes a range of socio-environmental consequences, one of which is shrinking cities and towns (SCT). SCT refer to the cities or towns that are experiencing population decline and economic downturn. In the existing literature, there have been numerous studies on SCT; however, there is a lack of study which investigates its knowledge domains. Therefore, this paper aims to conduct a scientometric analysis to achieve an outline of the SCT research status. Through the procedures of literature search and screening, a total of 716 SCT-related studies were extracted from the Scopus. The VOSviewer software system program was then utilized to visualize the present SCT-related studies. The visualization results revealed that the journal of Sustainability made significant contributions to the SCT research in terms of relevant publications. In addition, Haase, Annegret received the most co-citations, and was also the most productive author in this field. Furthermore, it was identified that current SCT research is mainly conducted in developed countries. Through the analysis of keywords, the emerging research topics were revealed. Discussions were further made from the perspectives of prevailing research methods, evaluation criteria, and solutions for SCT problems
