A novel parametric intuitionistic fuzzy entropy measure with applications to image edge detection 3359In digital image processing, edge detection is a fundamental operation used to identify intensity discontinuities in an image. In this paper, we propose a novel one-parameter generalization of an entropy …

Weibull-based reliability and profitability analysis of an industrial multi-state repairable system 3426Reliability is a primary concern in industrial manufacturing because operational interruptions can reduce production, cause substantial economic losses, and create workplace-safety risks. This study …
