A Continuation Multilevel Monte Carlo algorithm [PDF]

open access: yes, 2014
We propose a novel Continuation Multi Level Monte Carlo (CMLMC) algorithm for weak approximation of stochastic models. The CMLMC algorithm solves the given approximation problem for a sequence of decreasing tolerances, ending when the required error ...

Geometrical Tolerances—Separate, Combined or Simultaneous?

open access: yesApplied Sciences, 2023
The 14 geometrical tolerances defined in ISO 1101 are supplemented by the alphanumerical symbols defined in this standard and some other standards. The symbols CZ (combined zone), SZ (separate zones) and SIM (simultaneous requirement), which are crucial for the development of robust measuring programs for coordinate measuring machines, were introduced ...
