Badanie algorytmu identyfikacji parametrów modalnych wykorzystującego wiele rojów PSO pod kątem odporności na zakłócenia pomiarowe
PublicationW pracy przedstawiono wpływ zakłóceń pomiarowych na skuteczność algorytmu wykorzystującego wiele rojów PSO do identyfikacji parametrów modalnych w dziedzinie częstotliwości. W pracy przedstawiono wpływ poziomu szumu występującego w sygnale symulującym warunki pomiarowe przy rożnych poziomach zakłóceń. Ponadto otrzymane wyniki porównano z wynikami dla metod ERA i pLSCF-d. Uzyskane rezultaty wskazują, że proponowany algorytm w większości...

Curing behavior of epoxy/Fe 3 O 4 nanocomposites: A comparison between the effects of bare Fe 3 O 4 , Fe 3 O 4 /SiO 2 /chitosan and Fe 3 O 4 /SiO 2 /chitosan/imide/phenylalanine-modified nanofillers
PublicationIn this study, Fe3O4 magnetic nanoparticles (MNPs) were synthesized (B-MNP) and then modified with SiO2 to form Fe3O4/SiO2 core/shell MNPs. The Fe3O4/SiO2 MNPs were chemically functionalized with chitosan so as to gain Fe3O4/SiO2/Chitosan (CH-MNP). The CH-MNP was functionalized with a macromolecule containing imide and phenylalanine precursors to gain Fe3O4/SiO2/Chitosan/imide/phenylalanine based MNPs (CH-IM-MNP). The differences...

A robust sliding mode observer for non-linear uncertain biochemical systems
PublicationA problem of state estimation for a certain class of non-linear uncertain systems has been addressed in this paper. In particular, a sliding mode observer has been derived to produce robust and stable estimates of the state variables. The stability and robustness of the proposed sliding mode observer have been investigated under parametric and unstructured uncertainty in the system dynamics. In order to ensure an unambiguous non-linear...
