This paper addresses the problem of reliability improvement of k -out of - n system. It first looks at how series system is improved through the improvement of individual components with most reliable components. It also used redundancy (cold and hot) to improve the series system reliability.

This paper designed a Mathematical Model which provides a good description of blood flow regimes via constricted and unconstricted vessels that induces high blood pressure. It also presents a solution which will predict the rates of blood flow and the pressure profiles across the domain.
