 | We have conducted a body of work that examines weapon acquisition issues from a perspective that draws upon lessons learned from best practices in product development. Collectively, these practices comprise a process that is anchored in knowledge. Achieving the right knowledge at the right time enables leadership to make informed decisions about when and how best to move into various expensive acquisition phases. In essence, knowledge supplants risk over time. ... |

| Domain knowledge permeates all aspects of the engineering drawing analysis process, including understanding the physical processes operating on the medium (i.e., paper), the image analysis techniques, and the interpretation semantics of the structural layout and contents of the drawing. Additionally, an understanding of the broader reverse engineering context, within which the drawing analysis takes place, should be exploited. Thus as part of a wider project on the reverse engineering of ... |

| Interpretation of paper drawings has received a good deal of attention over the last decade. Related areas such as direct interpretation of human drawings (HCI), search and indexing of graphics databases, and knowledge representation in the domain of graphics and drawings understanding have also seen advances. One of the most interesting applications in this domain is the analysis of semantics in engineering drawings. |

| We provide a theory of the three dimensional interpretation of a class of line drawings called p-images, which are interpreted by the human vision system as parallelepipeds ('boxes'). Despite their simplicity, p-images raise a number of interesting vision questions: Why are p-images seen as three dimensional objects? Why not just as flat images?; What are the dimensions and pose of the perceived objects?; Why are some p-images interpreted as rectangular ... |

| The Ogden Air Logistics Center's tape contained good IGES files that represented the desired graphics, but the data itself and the declaration files did not meet the CALS requirements. This tape did not meet the 1840A requirements due to the creator's misinterpretations of the standard, therefore this test highlights needed changes to 1840A to correct these ambiguities. The specific results are that the 1840A header information was correct, yet not ... |

A typical such process for detail design of a machinery space is an ideal example. Immediately after preparation of separate system diagrammatics, the diagrams are arranged together, sometimes freehand, in order to quickly relate systems and zones; see Figure 1-1. Such relatively rough piping, component and wiring arrangements ... |
