Hardwood Lumber Scanning Tests to Determine NHLA Lumber Grades
This paper concerns the scanning, and grading of kiln-dried hardwood lumber. A prototype system is described that uses laser sources and a video camera to scan boards. The system automatically detects defects and wane, grades the boards, and then searches for higher value boards within the original board.

متن کاملStructured Inspections of Code
Cleanroom programming and code inspections independently provide evidence that it is more eecient to postpone the testing of code to a later stage than is usually done. This paper argues that an additional gain in quality and eeciency of development can be obtained by structuring inspections by means of an inspection protocol. The written part of such a protocol is prepared by the programmer be...
