Analytical design of ARL based on a modified EWMA control chart under ARIMA processes

In statistical process control, the performance of control charts is commonly evaluated using the average run length (ARL), which represents the expected number of observations required to signal a change in the monitored process. In many practical applications, quality character...

Role of Lewis centres on ethanol dehydrogenation over the Cu‐Cr/ γ ‐Al 2 O 3 system

Abstract A copper/chromium‐based catalytic formulation is evaluated for anaerobic ethanol dehydrogenation. Results indicate that the Cu–Cr interaction regulates dehydrogenation activity. This interaction increases the relative numbers of Lewis acid centres resulting in a superior...
