This book covers the various aspects of the development of an integrated product and process modelling system using advanced computer technologies. It describes languages and methodologies for developing an information reference model, system architectures, a link with emerging new standards such as ISO/STEP and CIM/OSA, and a new approach for the definition of model semantics. It discusses practical aspects of the usage and integration of computer aided design, planning and production systems, and shows how the reference model can be applied. Concrete practical examples are given for two demonstration parts: a sheet metal part and a ship propeller blade. Much attention has been devoted to making the subject matter easy to understand for a wide audience. The reference model is presented in easy-to-grasp chunks in a graphical, informal way, and many figures support the text. The reader should gain a clear impression of the various technical aspects of CIM systems using modern techniques corresponding to emerging new standards. Aspects of future systems are also included.

In a world filled with wizards, elves, vampires, pixies and humans lurks a threat more dangerous than anyone can imagine. After the battle between demons and wizards last year, everyone believes the world is safe once again. The students at Wonderment are eager to start a new school year.

Air Policing lessons are being lost through the generations. Air Policing is a forgotten concept in the modern day thinking and military planning within the United States Air Force. A modern Air Policing interpretation and approach may just provide the valuable capabilities needed to assist the often neglected "Phase IV" and "Phase V" campaign phases that focus on the transition between war and peace. Through case study analysis of several military conflicts over the last hundred years, it can be determined that Air Policing, if understood fully and applied properly, may fulfill a niche requirement in these circumstances. Air Policing principles may prove invaluable in finding both a militarily viable and politically acceptable path towards peace in future conflicts. Through analysis of the conflicts involving the British Air Control of Mesopotamia, the US withdrawal from Vietnam, Operation SOUTHERN WATCH, Operation NOBLE EAGLE, and Alaska NORAD Region Homeland Defense Alert Operations, the basic principles of modern day Air Policing at the operational and tactical levels were distilled.
