Robust estimation based nonlinear higher order sliding mode control strategies for PMSG-WECS [PDF]

open access: yesBulletin of the Polish Academy of Sciences: Technical Sciences, 2023
The wind energy conversion systems (WECS) suffer from an intermittent nature of source (wind) and the resulting disparity between power generation and electricity demand. Thus, WECS are required to be operated at maximum power point (MPP).

Dynamic planar scintigraphy for the rapid kinetic measurement of myocardial 123I-MIBG turnover can identify Lewy body disease

open access: yesEJNMMI Research, 2021
Background Using two static scans for 123I-meta-iodobenzyl-guanidine (123I-MIBG) myocardial scintigraphy ignores the dynamic response from vesicular trapping in nerve terminals. Moreover, the long pause between scans is impractical for patients with Lewy

Bacterial chromosome segregation by the ParABS system [PDF]

open access: yesOpen Biology, 2020
Proper chromosome segregation during cell division is essential in all domains of life. In the majority of bacterial species, faithful chromosome segregation is mediated by the tripartite ParABS system, consisting of an ATPase protein ParA, a CTPase and ...

Chaos Control in Gear Transmission System using GPC and SMC ‎Controllers [PDF]

open access: yesJournal of Applied and Computational Mechanics, 2022
Chaos is a phenomenon that occurs in some non-linear systems. Therefore, the output of the system will be heavily dependent on the initial conditions. Since the main characteristic of the chaos is an abnormal behavior of the system output, it should be ...
