Previous research on nonlinear oscillator networks has shown that chaos synchronization is attainable for identical oscillators but deteriorates in the presence of parameter mismatches. Here, we identify regimes which opposite occurs and show heterogeneity can synchronize conditions under cannot. This effect not limited to small mismatches observed random both homogeneous heterogeneous network ...

Among variety of 3D printing or additive manufacturing methods, the laser power bed fusion (LPBF) technology for metals is now widely spread. In this study, geometrical accuracy printed circular hole in a flat plate was investigated using aluminum alloy, Al-Si10-Mg, and polyamide, PA12. Some types imperfections have been reported, instance, lattice structures overhang structures, but distortion...

Accurate scatterometry and ellipsometry characterization of non-perfect thin films and nanostructured surfaces are challenging. Imperfections like surface roughness make the associated modelling and inverse problem solution difficult due to the lack of knowledge about the imperfection on the surface. Combining measurement data from several instruments increases the knowledge of non-perfect surf...

Surface and volume imperfections can significantly affect the performance of nanoscale or microscale devices used in photonics, optoelectronics scientific instrumentation. In this article we present an open source software package for Finite-Difference Time-Domain electromagnetic field calculations suitable on graphics cards. Its special features include handling realistic models imperfect obje...

Most of the existing multiple criteria decision-making methods handle one kind of the information imperfections at the same time. Stochastic methods and fuzzy methods constitute typical examples of these methods. However, several multiple criteria modelizations include simultaneously many kinds of the information imperfections. In this work, we propose a multiple criteria aggregation procedure ...

This study aims to investigate the effects of geometric imperfections on buckling of thin cylindrical shells due to global shear. To this end, more than 320 finite element models of cylindrical shells with different diameter to thickness ratios were prepared. Random imperfections with different amplitudes were applied to numerical models. The results revealed that global buckling of cylindrical...
