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 ...

In the present study, poly(ε-caprolactone) copolymers decorated with random inclusion of thermally stable and photo-dimerizing cinnamoyl groups were synthesized for an electrically-assisted material extrusion additive manufacturing technique named melt electrowriting (MEW). The absence thermally-induced reactions between maintained molten processable at elevated processing temperature while UV ...

The random demodulator is a recent compressive sensing architecture providing efficient sub-Nyquist sampling of sparse band-limited signals. The compressive sensing paradigm requires an accurate model of the analog front-end to enable correct signal reconstruction in the digital domain. In practice, hardware devices such as filters deviate from their desired design behavior due to component var...

This study is concerned with the asymptotic behavior of systems in which random sampling occurs; they are studied by a stochastic Lyapunov function method. The control loops under consideration consist of a random sampler (a sampling device which closes at a set of statistically described times in lieu of periodic intervals), a zero order hold, a linear plant, and a feedback element. Sampled sy...

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...

Sorting strategies are investigated in view of improving the dynamic aperture of the CERN-LHC. Local and quasi-local compensation of the random field shape imperfections are discussed and applied to simplified model of the LHC lattice. The most promising strategies are further investigated on a realistic LHC model with particular emphasis on the analysis of the robustness of the dynamic apertur...
