In this paper, we give new characterizations of exponential distributions on positive semigroups and we study the corresponding gamma distributions that govern semigroup products of independent and ...

Consider a complex subsystem such as a missile which undergoes testing in stages. That is, the subsystem is tested ni times with xi recorded successes at the i-th stage of testing. The reliability of ...
