Reducing the Effects of Inaccurate Fault Estimation in Spacecraft Stabilization
Journal of Aerospace Technology and Management, 2017 Reference Governor is an important component of Active Fault Tolerant Control. One of the main reasons for using Reference Governor is to adjust/modify the reference trajectories to maintain the stability of the post-fault system, especially when a ...

NONLINEAR SYSTEM SENSOR FAULT ESTIMATION
IFAC Proceedings Volumes, 2005 Based on the techniques of high gain observer and adaptive estimation,an algorithm is proposed in this paper for sensor fault estimationin nonlinear systems. It is essentially assumed that a high gainobserver exists for the fault-free system. A high gainadaptive observer is then designed for sensor fault estimation.The convergence of the algorithm is ...

Diversity and complexity in neural organoids
FEBS Letters, EarlyView.Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Decentralized Fuzzy Observer-Based Fault Estimation for Nonlinear Large-Scale Systems
IEEE AccessThis paper presents a fault estimation technique based on the decentralized fuzzy observer for nonlinear large-scale systems, which are considered to be consisted of fuzzy subsystems and uncertain interconnections.

Thermodynamic Estimation of Transformer Fault Severity
IEEE Transactions on Power Delivery, 2015 Conventional practice for transformer dissolved gas analysis (DGA) is to use concentrations of several fault gases, with or without total dissolved combustible gas, for evaluating apparent fault severity. We suggest a simpler approach based on the normalized energy intensity (NEI), a quantity related directly to fault energy dissipated within the ...

The human gut microbiome across the life course
FEBS Letters, EarlyView.Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

On fault tolerant control structures incorporating fault estimation [PDF]
Archives of Control Sciences, 2016 AbstractThe paper provides the minimal necessary modifications of linear matrix inequality conditions for the mixed H2/H∞control design as well as for the augmented observer-based fault estimation to be mutually compatible in joint design of integrated fault estimation and fault tolerant control.

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
