conclusions graft failure is more likely to occur in patients with higher serum creatinine levels. results there was a positive association between the serum creatinine level and graft failure (hr = 5.13, p < 0.001). a one unit increase in the serum creatinine level suggests an increased risk of graft failure of up to 5.13 times. the serum creatinine level significantly decreased over time (95%...

In this paper, optimization of periodic inspection interval for a two-component system with failure dependency is presented. Failure of the first component is soft, namely, it does not cause the system stop, but it increases the system operating costs. The second component’s failure is hard, i.e. as soon as it occurs, the system stops operating. Any failure of the second component increases the...
