    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (94 KB)

    Summary form only given. The causal knowledge of how a specific behavior of a device arises from the functions of its components is useful for tasks like diagnosis, redesign, and prediction. This knowledge is usually represented using causal sequences (CSs). Annotations on the transitions in a CS often refer to the functions of device components as causes for the state transitions. The CS represen... View full abstract»
