The skipping strategy to reduce the effect of the autocorrelation on the T (2) chart's performance
(Springer, 2015-10-01)
In this article, we consider the T (2) control chart for bivariate samples of size n with observations that are not only cross-correlated but also autocorrelated. The cross-covariance matrix of the sample mean vectors were ...
Comparative study of inversion-based and observer-based approaches for fault diagnosis in DC-DC converters
(2017-07-07)
Recently, model-based approaches have been proposed for fault diagnosis as an emerging alternative to traditional techniques. Particularly, the inversion-and observer-based were proposed for fault diagnosis as successful ...
Grid Impedance Detection Based On Complex Coefficient Filter and Full-order Capacitor Current Observer for Three-phase Grid-connected Inverters
(2023-02-01)
This article proposes a new grid impedance detection method incorporating the complex coefficient filter (CCF) with full-order capacitor current observer for a T-type three-level grid-connected inverter controlled by the ...
Self-assembled FePt nanocrystals with large coercivity: Reduction of the fcc-to-L1(0) ordering temperature
(Amer Chemical Soc, 2006-08-30)
Herein we report the synthesis and properties of Fe55Pt45 nanoparticles, both monodisperse and self-assembled into hexagonal close-packed and cubic arrays of 4.0 +/- 0.2 nm size in an L1(0) structure, obtained by a modified ...

Product-based sliding mode observer for biomass and growth rate estimation in Luedeking-Piret like processes
(Institution of Chemical Engineers, 2016-01)
The on-line estimation of non-measurable substances and key process variables is relevant for the real-time monitoring of the bioprocesses. This paper deals with the on-line estimation of microbial growth rate and biomass ...
A novel PV-MPPT method based on a second order sliding mode gradient observer
(Pergamon-Elsevier Science Ltd, 2018-11)
Leading PV system operation at its Maximum Power Point (MPP) is crucial to improve the overall system efficiency and reduce the solar energy cost. In such a sense, this paper presents a closed-loop Maximum Power Point ...
An acoustic source model for asymmetric intraglottal flow with application to reduced-order models of the vocal folds
(2019)
The complex three-way interaction between airflow, tissue, and sound, for asymmetric vocal fold vibration, is not well understood. Current modeling efforts are not able to explain clinical observations where drastic ...
