The Model Reference Adaptive System (MRAS) is effective for speed control in sensorless Induction Motor (IM) drives, particularly at zero and very low speeds. This study enhances MRAS's resilience and dynamic performance by integrating an Adaptive Neuro-Fuzzy Inference System (ANFIS) controller into sensorless vector-controlled IM drives. The research addresses challenges related to parameter uncertainties, load variations, and external disturbances through the combination of MRAS and ANFIS.

Article Synopsis
  • The study examined a tropical estuary affected by pollutants, highlighting that sediment had higher contamination levels than surface water, especially in heavy metals and hydrocarbons.
  • The microbial community analysis found that Proteobacteria were dominant in both water and sediment, with significant differences in microbiome composition and functionality between the two environments.
  • The sediment microbiome showed adaptations to pollutants, suggesting its potential use for bioremediation efforts in cleaning up the estuary.

Background: Among frequent healthcare users is a small group called "high-care users", with ≥ 10 hospital visits annually. They consume a disproportionate share of the healthcare budget, and their care is often inappropriate and unnecessary.

Objectives: To assess the prevalence and determinants of persistent high-care (PHC) use (≥ 10 visits in two consecutive years) among National Health Insurance Authority (NHIA) enrollees.

Detecting faulty pipelines in water management systems is crucial for ensuring a reliable supply of clean water. Traditional inspection methods are often time-consuming, costly, and prone to errors. This study introduces an AI-based model utilizing images to detect pipeline defects, focusing on leaks, cracks, and corrosion.

Background: The incidence of lung cancer is unequally distributed in France. Although several studies have shown a link between the socioeconomic environment of populations and the incidence of cancer, the contribution has not been quantified. We aimed to analyse the geographical variability of lung cancer incidence in Normandy and calculate the proportion explained by the socioeconomic environment.
