“One Cannot Leave It Undecided”: On the Dynamic Production of Scoring Decisions in the School Inspection Process
This PhD thesis addresses how inspection scores are dynamically produced – especially the ways in which school inspection teams decide upon how to score the schools that they inspect. This research thereby fills a gap between research focussing on inspection policy and research focussing on the …

A knowledge-based machine vision system for automated industrial web inspection
Most current machine vision systems for industrial inspection were developed with one specific task in mind. Due to the requirement for real-time operation, these systems are typically implemented in special purpose hardware that performs very specific operations. Hence, these systems inflexible in …
