This book focuses on the latest developments in the field of engineering. The first chapter presents software engineering and ontology development. Chapter Two discusses metal rapid prototyping technologies. Chapter Three presents a complete description of the Scalable High Efficiency Video Coding (SHVC) architecture and its application scenarios; comprehensively analyzes the recent efforts toward an improved SHVC compression efficiency; and introduces two novel SHVC improvement solutions, notably an improved SHVC Merge mode and a novel SHVC Joint Layer mode. Chapter Four examines a refined analytical-experimental modal testing method for polymeric damping materials. Chapter Five focuses on the recent published advances in biometrics to date, considering them not only in terms of their relative contributions but also in referral to relevant government and industry authentication frameworks and guidelines. Chapter Six discusses control of a class of 1D Bose-Einstein Condensate (BEC) condensate via linear-type feedback.
