Influence of the hydraulic pump unit on the quality of the rolled surface

Литьë и металлургия, 2021
To ensure the competitiveness of rolled metal in the modern market, the decisive factor is the quality of the rolled surface (defects with a depth of no more than 0.2 mm are allowed without stripping). Rolling processing is a source of formation of small

Response-surface-model-based system sizing for nearly/net zero energy buildings under uncertainty [PDF]

, 2018
Properly treating uncertainty is critical for robust system sizing of nearly/net zero energy buildings (ZEBs). To treat uncertainty, the conventional method conducts Monte Carlo simulations for thousands of possible design options, which inevitably leads
