Enhancing the power quality of dual rotor wind turbines using improved fuzzy space vector modulation and super twisting sliding techniques.

In the field of control, many approaches have been used to control generators, where indirect vector control (IVC) is considered one of the most prominent of these approaches due to its many advantages. This approach has a fast response time (RT) and is quite easy to realize. However, its reliance on traditional controllers makes this approach less efficient and less effective if the system parameters change.

Psychometric properties of the Benign and Malicious Envy Scale: A cross-cultural study in the Arab Maghreb countries.

Background: The Benign and Malicious Envy Scale (BeMaS) is designed to assess the trait of envy and evaluate individual differences in people's tendency to experience benign or malicious envy towards superior comparison standards.

Objective: This study aimed to examine the factor structure of the BeMaS in Arab culture through exploratory and confirmatory factor analysis and to ensure the measurement equivalence of the benign and malicious envy scale across three countries in the Arab Maghreb region (Algeria, Tunisia, and Morocco).

Methods: The study was conducted on a sample of 1047 students from various universities across three countries, Algeria (n = 401), Tunisia (n = 289), and Morocco (n = 357), and implemented a cross-sectional study design.

Treatment of tannery effluent by adsorption onto fly ash released from thermal power stations: Characterisation, optimization, kinetics, and isotherms.

Fly ash is a significant pollutant in thermal power stations. Although this waste harms the environment and humans, it is badly removed and managed, and only a few studies are interested in this waste. For that, this study aims to valorise fly ash into potential adsorbents to treat tannery effluents for the first time.
