Natural images are meaningful to humans and used for a variety of tasks. The specific task to be performed dictates the assessment of an image’s suitability to the task. This work considers image assessment (IA) as a task-specific evaluation and examines the performance of a variety of objective IA algorithms for three different assessment tasks: fidelity assessment, quality assessment, and uti...

The study proposed in this paper consists of devising a method to account qualitatively and quantitatively for the human factor in verifying the Integrity Level of Safety system (SIL) assigned to the machinery. It is called “operational SIL”, which may differ from the design SIL, due to the impact of human and organizational factors (H&OF) in the operational phase. There are two crucial aspects...

For self-regulated learning to be effective, students need to be able to accurately assess their own performance on a learning task, and to select an appropriate new learning task in response to that self-assessment. This study investigated the use of video-based modeling examples to teach selfassessment and task-selection skills. Students in both the experimental and control condition observed...
