RGB-D Image Encryption Using a Hyperchaotic System and Quaternion Gyrator Transform

An RGB-D image encryption scheme is presented by combining a newly constructed 4D-ICTM hyperchaotic system with a reformulated quaternion gyrator transform (QGT). The proposed 4D-ICTM dynamics arise from the nonlinear combination of the ICMIC and Chebyshev maps with the tanh func...

Prioritizing environmental anxieties and mitigation strategies across eco-anxiety, climate, health, economic, and social domains

This study assesses environmental anxieties and prioritizes strategies to address them using an integrated expert-based multi-criteria framework. The Analytic Hierarchy Process (AHP) and Fuzzy TOPSIS are combined to identify, weight, and rank sub-anxieties across five domains: ec...

cIGW-SC: an intelligent chaotic hybrid grey wolf and sine cosine optimizer for complex engineering design problems

For intelligent systems designed to solve complex engineering design problems, premature convergence and the imbalance between exploration and exploitation remain key challenges for high-dimensional, multimodal, and composite problems. Existing approaches, including the Grey Wolf...

Design of a deep learning-driven multidimensional evaluation model for youth training system performance assessment

In this paper, a deep learning driven multidimensional evaluation framework is proposed to evaluate the performance of Youth Training System (YTS). In order to reduce the subjectivity of manual scoring and static weight, the framework organizes resources organization, training ex...
