• Random number of units for K-out-of-n systems 

      Ito, Kodo; Zhao, Xufeng; Nakagawa, Toshio ( Elsevier Inc. , 2017 , Article)
      This paper takes up the reliability and preventive replacement problems for a K-out-of-n system, where K is a stochastic parameter provided. Firstly, we consider the case when K is predefined as constant numbers as is done ...

    • A rich learning lesson using the Poisson distribution 

      Al-Saleh, Mohammad Fraiwan ( Elsevier B.V. , 2007 , Article)
      In this note, we explore the rich information about inference that the Poisson distribution has. The source of this information is mainly the fact that the mean and variance of this distribution are equal.
