Generalized modal reduction method for the dynamic analysis ofrotating mechanical systems

The paper proposes modal reduction method of the dynamic systems composed of linear nonconservative sub-systems coupled by nonlinear discrete couplings. Classical approach to the modal reduction is based on thetransformation of the generalized coor...

Extraordinary high-temperature behavior of electrically conductive Hf7B23Si22C6N40 ceramic film

The high-temperature behavior of an electrically conductive, opaque and hard Hf7B23Si22C6N40 ceramic film with an amorphous structure was systematically investigated in air up to 1700 °C and inert gases up to 1600 °C. The film was prepared by reactive pulsed dc magnetron sputter de...

Optimization and Testing of Money Flow Index

The paper deals with whether the Money Flow Index (MFI) can still be used successfully for trading, and whether the parameters recommended in the literature are the best that an investor can use. Simulations in randomized time interval for the largest companies in the S&P&...

Self-organization of vapor-deposited polyolefins at the solid/vacuum interface

Interactions between polyolefins and silicon substrates are investigated upon their physical vapor deposition under vacuum. Molecular dynamics simulations show that polyolefins unfold upon adsorption and that two macromolecules suffice to produce a stable nucleus. Supersharp probe AFM measurements reveal&#...

Effect of positive pulse voltage in bipolar reactive HiPIMS on crystal structure, microstructure and mechanical properties of CrN films

CrN films were prepared using three different configurations of the HiPIMS discharge mode and the substrate holder potential. We investigate the effect of a positive pulse voltage (30–400 V) in bipolar HiPIMS on the crystal structure, microstructure and resulting mechanical properties of...
