...Leland W. Weiss A novel free piston expander (FPE) has been designed and modeled for energy sustainability applications. Specifically, the device has been designed to produce power from low-temperature energy sources as part of a larger low-temperature steam system. Due to the needs imposed...

.... The applicability of the proposed decision validation metrics is examined for designs with either a discrete or continuous set of design alternatives. The approach is demonstrated through an illustrative example of a robust engine piston design. In Eqs. 15 , 16 , 17 , the decision metrics are evaluated...

... reliability given certain incomplete information. As a demonstration, we apply the method to design an optimal piston-ring/cylinder-liner assembly under surface roughness uncertainty. Information on surface roughness uncertainty is incomplete in that their pdf’s are not known; only a finite number...

... for distinguishing the best design alternative and conducting more efficient computer experiments. We illustrate the proposed methodology with two robust design examples—a simple container design and an automotive engine piston design with more nonlinear response behavior and mixed continuous-discrete design...
