Abstract: A method for managing a computer simulation is disclosed. The method includes providing an interface for soliciting input of initialization parameters for generating a training exercise and receiving from the interface initialization parameters entered by a user. The method further includes executing the training exercise defined by the initialization parameters and providing a second interface for soliciting input of execution parameters for managing execution of the training exercise. The method further includes receiving from the second interface execution parameters entered by a user and modifying execution of the training exercise as defined by the execution parameters. The method further includes storing performance data associated with performance of participants during execution of the training exercise and providing a third interface that provides a summary of the performance data.

Abstract: A method and apparatus are provided for producing a signature having a backbone fold defining a closed end and an intermediate fold transverse to the backbone fold using a reduced width of paper coming from a roll. The method and apparatus reduce gusset wrinkles adjacent the folds by slitting ribbons formed from the paper web along a trail edge and a lead edge of a closed end forming the signature. Preferably, the slitting operation leaves an uncut portion of the closed end of the signature extending across the intermediate fold from a side edge to the trail edge to stabilize the ribbon at the area to receive the intermediate fold. The lead edge and trail edge are slit very substantially to expose long areas of fibers for gluing to form a book backbone.
