An analytic technique for statistically modeling random atomic clock errors in estimation [PDF]
Minimum variance estimation requires that the statistics of random observation errors be modeled properly. If measurements are derived through the use of atomic frequency standards, then one source of error affecting the observable is random fluctuation ...

From Copper Nanoparticles to Alumina Encapsulated Porous Layers With Enhanced Mechanical Stability
Advanced Materials Interfaces, EarlyView.This study analyzes the synthesis‐structure relation of individual Cu nanoparticles and highly porous nanoparticle‐based Cu films using different sputtering‐based nanoparticle sources. The inherent mechanical instability of the films is tackled with Al2O3 encapsulation through atomic layer deposition, enabling 4‐fold increase in critical force in ...

Ductility Tuning via Cluster Network Characteristics of Porous Components
Advanced Materials Technologies, EarlyView.Network optimization via cluster characteristics induced by interaction of stress concentration is proposed, demonstrating increased cluster size and dispersion in non‐uniform porous components. The optimized structures exhibit, for the first time, that enhanced ductility and damage progression is controllable through zigzag cluster network designed by
