How many Decomposition Types do we need ?

Decision Diagrams (DDs) are used in many applications in CAD. Various types of DDs, e.g. BDDs, FDDs, KFDDs, di er by their decomposition types. In this paper we investigate the di erent decomposition types and prove that there are only three that really help to reduce the size of DDs.

How many PET tracers do we need?

The recognized need for new PET tracers is associated with increases in available PET instrumentation and with unmet clinical challenges in the early diagnosis and staging of diseases. The clinical success of (18)F-FDG PET has resulted in the acceptance of biologic signals as part of disease management. The advantages of PET technology over SPECT will lead to the introduction of new PET tracers...

How Many Diagnoses Do We Need?

A known limitation of many diagnosis algorithms is that the number of diagnoses they return can be very large. This raises the question of how to use such a large set of diagnoses. For example, presenting hundreds of diagnoses to a human operator (charged with repairing the system) is meaningless. In various settings, including decision support for a human operator and automated troubleshooting...
