Calculation of static transmission errors associated with thermo-elastic coupling contacts of spur gears [PDF]

Vibroengineering Procedia, 2018
The static transmission error is one of the key incentives of gear dynamics and addressed by many scholars. However, the traditional calculation method of static transmission errors of spur gears does not take into account the influence of thermo-elastic coupling caused by the gear temperature field, and it limits the accuracy of the dynamic ...

General radar transmission codes that minimize measurement error of a static target

, 2006
The variances of matched and sidelobe free mismatched filter estimators are given for arbitrary coherent targets in the case of aperiodic transmission. It is shown that mismatched filtering is often better than matched filtering in terms of estimation accuracy.
