This book presents thoroughly revised tutorial papers based on lectures given by leading researchers at the International Training School on Domain Modeling and the Duration Calculus, held in Shanghai, China, in September 2007 as an associated event of ICTAC 2007, the 4th International Colloquium on Theoretical Aspects of Computing. The four tutorial papers presented provide competent coverage of software security, domain modeling of software engineering, and duration calculus for real time systems - originating from lectures of leading experts in these fields from Europe and Asia. Topics addressed in detail are: development of real-time systems, domain engineering using abstract modeling, the area of duration calculus, and formal methods like language description using the operational semantics approach.
