In stand-alone photovoltaic (PV) systems, the main goal is to control the current that the inverter feeds to the load. In this paper, the performance of predictive current control (MPCC) is tested and evaluated for a stand-alone photovoltaic (PV) system. Our evaluation spans various current amplitudes and frequencies, aiming to demonstrate its robust performance and practical applicability. The MPCC method employs a discrete-time model of the system, enabling the prediction of future values of the load current for all potential volt-age vectors generated by the inverter. Implementing the MPCC strategy on RL (resistor-inductor) load alimented by a PV inverter offers the advantage of simplified implementation and significantly reduced computing time. Simulation and experimental results are presented to prove the efficiency and practical applicability of the proposed control. Both results conclusively demonstrate the high efficacy of MPCC in managing a stand-alone photovoltaic (PV) inverter across various current amplitudes and frequencies, ensuring reliable and robust performance

L’énergie solaire photovoltaïque (PV) est parmi les énergies renouvelables la plus utilisée pour la production de l’énergie électrique. Le point le plus important en ce qui concerne l'intégration des systèmes photovoltaïques au réseau est le convertisseur de puissance, notamment les onduleurs qui ne sont pas tout à fait capables de fonctionner en mode avancé. Les nouvelles techniques en développement permettent d'améliorer les performances des onduleurs en assurant l'intégration correcte des systèmes photovoltaïques en tenant compte des caractéristiques du réseau. D’où, des exigences pour le contrôle avancé de l'onduleur connecté au réseau permettent le contrôle complet de l'énergie photovoltaïque fournie, toute en assurant une bonne qualité d’énergie, un faible Taux de Distorsion Harmonique (THD) des courants injectés dans le réseau et le contrôle de la puissance active et réactive. Ce papier présente, les configurations, la classification et les topologies des différents types d’onduleurs PV connectés au réseau. Un résumé concis des méthodes de contrôle pour les onduleurs monophasés et triphasés est également présenté. Un banc d’essai a été réalisé pour la validation expérimentale des techniques de contrôle proposées et développées.

Studies within oncology show that patients suffering from cancer report having a stronger feeling of hope than the general population. Such findings correspond to the pivotal role hope has in Henrik Wergeland’s (1808–1845) six so-called deathbed poems. Writing of illness the way Wergeland does is a part of the tradition of autobiographical literature called pathography. However, also having a dead person as the narrating voice situates some of the poems within the experimental genre of autothanatography. I will discuss how Wergeland’s poems through the use of the literary device of prosopopeia establish an unnatural narrative containing hope for the afterlife. The study is situated within the field of literature and medicine, and shows how modern narratological insights can be used as a means of bringing forth new perspectives on the pathography genre.

INTRODUCTION: Cholera outbreaks in Nigeria are often associated with high case fatality rates; however, there is a dearth of evidence on context-specific factors associated with the trend. This study therefore aimed to identify and quantify the factors associated with cholera-related deaths in Nigeria. METHODS: Using a cross-sectional design, we analysed surveillance data from all the States that reported cholera cases during the 2018 outbreak, and defined cholera-related death as death of an individual classified as having cholera according to the Nigeria Centre for Disease Control case definition. Factors associated with cholera-related death were assessed using multivariable logistic regression and findings presented as adjusted odds ratios (ORs) with 95% Confidence Intervals (95% CIs). RESULTS: Between January 1 and November 19, 2018, 41,394 cholera cases were reported across 20 States, including 815 cholera-related deaths. In the adjusted multivariable model, older age, male gender, living in peri-urban areas or in flooded states, infection during the rainy season, and delay in seeking health care by >2 days were positively associated with cholera-related death; whereas living in urban areas, hospitalisation in the course of illness, and presentation to a secondary hospital were negatively associated with cholera-related death. CONCLUSION: Cholera-related deaths during the 2018 outbreak in Nigeria appeared to be driven by multiple factors, which further reemphasises the importance of adopting a multisectoral approach to the design and implementation of context-specific interventions in Nigeria.

En étudiant la mise en oeuvre des politiques d’intégration participatives au sein d’une maison de quartier à Paris et d’une autre à Helsinki, cet article s’interroge sur la manière dont un lien de citoyenneté plus solide est tissé entre les femmes migrantes et la société française et finlandaise. L’observation in situ au coeur des dispositifs participatifs du café des mères à Helsinki et de l’atelier d’écriture à Paris montre que, bien que les politiques d’intégration participatives poursuivent officiellement des objectifs similaires, elles produisent en pratique un attachement civique de nature différente cantonné aux cadres normatifs du maternalisme et de la citoyenneté communautaire dans le premier cas, et à du féminisme et de la citoyenneté politique dans le second. Confrontée à l’insuffisance du cadre interprétatif des « modèles d’intégration » nationaux, cette recherche examine la variation des trois techniques du « travail d’attachement » que déploient les agents de terrain à la lumière d’éléments explicatifs locaux, comme la trajectoire des institutions et l’organisation des dispositifs comparés. Elle identifie comme apport principal de l’ethnographie aux comparaisons internationales la possibilité de développer des analyses multiniveaux et des comparaisons partielles, mais réalistes.

Eugene Jolas introduced Caresse Crosby and Kay Boyle to one another in Paris on May 19, 1928 at the Bal Nègre, the Montparnasse nightclub famous for black jazz. Harry and Caresse Crosby were known then as an ultramodern, raffish couple determined to establish themselves as poets and patrons of writers and artists. Boyle had made early, significant contributions to the avant-garde literary scene in the United States publishing in Broom, Poetry, This Quarter, and transition. Despite her emerging success, Boyle was in dire financial circumstances. The Crosbys quickly became concerned with Boyle’s welfare and an intimacy between them developed. Their emotional involvement intertwined with their interest in mutual literary endeavors, and the Crosbys’ Black Sun Press published Boyle’s first collection of short stories and her translation of the first chapter of René Crevel’s Babylon, “Mr. Knife, Miss Fork.” In 1932, three years after Harry’s scandalous death, Caresse published Boyle’s translation of Raymond Radiguet’s The Devil in the Flesh, and Boyle’s novel Year Before Last under her own imprint, Crosby Continental Editions. Her friendship with the Crosbys also provided Boyle with material for a number of scenes in her fourth novel, My Next Bride (1934). Boyle’s senior by ten years, Caresse was Kay’s confidante, an older, wiser sister of sorts. Over the next four decades, however, the relationship between them balanced out as Boyle’s reputation flourished as a writer and social activist, and Crosby made great efforts to promote world peace while she continued to support the work of numerous artists and writers. Both women rejected convention’s dictates about romance, marriage, and motherhood. Theirs was an altruistic friendship based on protecting one another’s honor and careers.
