    Abstract: Backbreak in the mining industry presents a considerable challenge, impacting both safety and operational efficiency. Accurate prediction of backbreak is therefore a critical endeavour. This study rigorously evaluates four advanced machine learning (ML) techniques—Lagrangian Support Vector Machine (LSVM), Radial Basis Function Neural Network (RBFNN... Show More

    Abstract: In today's applications of block ciphers, the substitution box (S-box) serves as a critical nonlinear component that is essential for generating complex ciphertext. S-boxes that exhibit lower differential uniformity and increased nonlinearity are more adept at resisting cryptanalytic efforts. The paper proposes that the construction of an 8x8 S-box... Show More

    Abstract: One of the key challenges in preventing major process safety accidents in an operating plant is the lack of an integrated system/model that brings together the risks posed by the deficiencies / deviations on the safety critical barriers, for operational decision making. Based on this context, an exploratory study was undertaken to develop a model/f... Show More

    Abstract: During drilling operations, the use of drilling fluid plays a critical role, and over time, there has been considerable interest in enhancing drilling fluid characteristics in order to improve performance, reduce costs, and prevent environmental pollution. Deviating from conventional additives, recent studies have explored the use of alternative ma... Show More
