Fault Diagnosis of Hybrid Systems Using Particle Filter Based Hybrid Estimation Algorithm

Chemical Engineering Transactions, 2013
Hybrid systems are composed of discrete event dynamic systems and continuous time dynamic systems, which interact with each other. The fault diagnosis of hybrid systems is particularly difficult.

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

FEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Actuator Fault Estimation Based on Adaptive H-infinity Observer Technique [PDF]

, 2009
In adaptive observer methods for actuator fault estimation, the system has to satisfy the condition of the Strictly Positive Realness (SPR). However, some practical systems may fail to satisfy the SPR condition.

Adaptive Observer-Based Fault Estimation for Stochastic Markovian Jumping Systems

Abstract and Applied Analysis, 2012
This paper studies the adaptive fault estimation problems for stochastic Markovian jump systems (MJSs) with time delays. With the aid of the selected Lyapunov-Krasovskii functional, the adaptive fault estimation algorithm based on adaptive observer is ...

Attitude Fault-Tolerant Control of Aerial Robots with Sensor Faults and Disturbances

Drones, 2023
In this paper, sensor fault diagnosis and fault tolerant control strategy are investigated for quadcopters under sensor faults and disturbances. We propose the fault diagnosis estimation system and the fault-tolerant control (FTC) method.

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

FEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

SIMPLIFIED ESTIMATION OF DESIGN FAULT DISPLACEMENT FOR BURIED PIPELINES AT FAULT CROSSING

Proceedings of the XI International Conference on Structural Dynamics, 2020
A set of simplified expressions are derived for estimating the design fault displacement for pipelines crossing active faults by considering alternative scenarios, seismicity levels, and the pertinent uncertainties. Buried steel pipelines are an efficient and safe means of oil and gas onshore transportation and provide a direct link between extraction,
