A Physics-Guided Statistical Framework for Bearing Fault Diagnosis Under Unit Variability and Rotational Speed Uncertainty

Reliable bearing fault diagnosis must differentiate between defects and normal-operation-condition variation. The predictor must remain accurate when shaft speed is uncertain. Conventional accuracy-driven models often ignore false-positive rates and fail to accurately locate faul...

Revolutionizing hospital supply chain: machine learning for predictive risk assessment

Purpose The purpose of this study is to identify and prioritize the risks associated with healthcare supply chain with a focus on hospital’s internal supply chain. Design/methodology/approach The study presents a machine learning model for hospital supply chain risk assessment. T...

Leaf-inspired ZnO-Cr2O3/epoxy coatings with tailored visible–NIR reflectance for spectral camouflage applications

The difference in spectral response between the target and the background is very crucial to avoid target detection by surveillance systems in the visible (VIS) and near-infrared (NIR) spectral regions. In this study, ZnO–Cr 2 O 3 /epoxy composite coatings were developed using co...

Sepiolite reinforced alginate-based hydrogels for drug delivery applications

Abstract Cephradine is a first-generation bactericidal cephalosporin widely used for the treatment of urinary, respiratory and skin infections. When it is taken with the amount of 8–17%, this drug binds to serum, whereas almost 83–92% of it is released via the urinary tract witho...

Design and engineering of layered double hydroxide-based composites for efficient wastewater treatment

Layered double hydroxides (LDHs), often referred to as hydrotalcite components, have gained popularity as wastewater treatment solutions due to their distinct lamellar structure, changeable metal arrangement, excellent anion exchange efficiency, and notable memory effect. However...
