Does risk attitude (aversion or attraction) vary with the level of the income at risk? About half of our subjects chose to insure all levels, whereas another half chose instead not to insure low levels, but to insure high levels.

The decision to transfer or share an insurable risk is critical for the maker’s economy. This paper deals with this decision, starting definition of a function that represents difference between expected utility insuring, without deductibles, and not insuring. Considering constant relative aversion (CRRA) function, we provide pattern potential policyholders as their wealth level. obtained rule ...

Given an arbitrary Petri net structure, the deadlock prevention procedure presented here determines a set of linear inequalities on the marking of a Petri net. When the Petri net is supervised so that its markings satisfy these inequalities, the supervised net is proved to be deadlock-free for all initial markings that satisfy the supervision constraints. Deadlock-freedom implies that there wil...

We present a new method for the synthesis-forinitializability of asynchronous state machines. Unlike existing approaches, our method incorporates a state assignment step. State assignment is critical, since initializability may be precluded by poor choice of state assignment. Also, we present precise conditions on hazard-free logic, to insure that the circuits are physically initializable.

We studied the effects of administering exogenous surfactant for the treatment of respiratory distress in premature neonates (born before 37 weeks of gestational age [GA]) and compared the role of different risk factors on the outcome as well as survival rate. All the neonates (242) suffered from moderate to severe respiratory distress, identified by clinical signs, chest X-ray, respiratory dis...
