Consider the following two activity diagram fragments labeled Fragment 1 and Fragment 2. The JoinSpecification for Fragment 1 is completely specified, but the JoinSpecification for Fragment 2 is not.
Which join specification for Fragment 2 will make it exhibit the same behavior as fragment 1? Assume that activities with the same names exhibit the same behavior
Given a system for keeping birds away from airports One component, described by the following diagram directs audio signals at birds that approach a runway, its parts, as part properties, are typed by blocks.
A systems engineer has identified some blacks that type the pan properties, but as the design becomes more specific, the engineer discovers that these blocks exist in multiple variants.
What modeling choice does the engineer face at this point?
