An Efficient Library for Reliability Block Diagram Evaluation

open access: yesApplied Sciences, 2021
Reliability Block Diagrams (RBDs) are widely used in reliability engineering to model how the system reliability depends on the reliability of components or subsystems. In this paper, we present librbd, a C library providing a generic, efficient and open-

Evaluating treatment effects reliably

open access: yesBMJ, 2002
The introduction, more than half a century ago, of properly randomised trials in which the treatment allocation was rigorously concealed was a watershed in the evaluation of treatment effects.1 But this major advance did not come out of the blue: as was highlighted at a recent conference in Oxford (Beating biases in therapeutic research: historical ...
