Volume 6, Issue 2 of the Journal of Innovation and Software examines the convergence of Artificial Intelligence (AI) and applied engineering. Key research highlights include the optimization of Large Language Models (LLMs) via prompt engineering and their application in technical incident management. Software quality is a central theme, addressing technical debt in deep learning tools and requirements debt. In healthcare, advances in biometric authentication for smart hospitals, surgical assistance, and dementia prediction are presented. Additionally, solutions for industry and security are explored, including dynamic encryption with noisy injection, process automation with n8n, and inventory management.
