Preliminary identification of plugging of open-ended pipe piles based on their dimensions, ahead of driving, is explored in this study using data analytics. Piles can be unplugged, plugged, or internally plugged, depending on their dimensions, and geotec...

In order to use files in database federations, we propose to migrate file data into a relational database. Integrating the database in a federation is then well-understood. This procedure has the advantage that a "real" database is handled supporting tra...
