Numerical Study Using Narx To Improve Pipe Vibration In Dosing Pump Systems, Shmoos Rahem Mazal, Mohammed Jawad Mohammed, Mahmoud Mustafa Mahdi

Engineering and Technology Journal

Pressure pulsation is a serious problem in the piping system. It is generated at the beginning and end of the water-pumping process, or when valves suddenly close. The high turbulence of fluid particles in the presence of pressure waves causes multiple stresses on the pipe walls, requiring maintenance and eventual replacement over time. In this research, an experimental setup for a piping system vibration model induced by pulsating pressure is designed, developed, and fabricated. The objective of the present work is to create a MATLAB program using the NARX method at the beginning of the Neural Network time series. Nonlinear …

Between Religion And Feminism: Analysis Of Gendered Religious Discourse On Moroccan Social Media And Its Societal Effects, Roua Chkouni

Faits de Langue et Société (FLS)

This article examines gendered religious discourse on Moroccan social media and analyses its effects on representations of identity. Taking a multidisciplinary approach that combines gender sociology, sociology of religion and digital studies, this research draws on critical and digital discourse analysis, online ethnography and field observations. The results highlight how this content, by exploiting the virality and interactivity inherent in these platforms, contributes to the reproduction and reformulation of patriarchal norms. The study thus highlights the tension between the modernisation of media, the reconfiguration of religious authority and the persistence of gender hierarchies in the contemporary Moroccan context.
