Multi-physics based Simulations of an Oleo-pneumatic Shock Absorber System for PHM

open access: yesInternational Journal of Prognostics and Health Management, 2017
The paper presents multi-physics (Mechanical, Thermal, Hydraulic, and Pneumatic) based modelling and simulation of an Oleo-pneumatic shock absorber with fault capabilities. The fault simulated in this model is leakage due to eccentricity.

Formal verification of a software countermeasure against instruction skip attacks [PDF]

open access: yes, 2013
Fault attacks against embedded circuits enabled to define many new attack paths against secure circuits. Every attack path relies on a specific fault model which defines the type of faults that the attacker can perform.

Representing Small Commercial Building Faults in EnergyPlus, Part II: Model Validation

open access: yesBuildings, 2019
Automated fault detection and diagnosis (AFDD) tools based on machine-learning algorithms hold promise for lowering cost barriers for AFDD in small commercial buildings; however, access to high-quality training data for such algorithms is often difficult

Sensor-fault tolerance using robust MPC with set-based state estimation and active fault isolation [PDF]

open access: yes, 2014
In this paper, a sensor fault-tolerant control (FTC) scheme using robust model predictive control (MPC) and set theoretic fault detection and isolation (FDI) is proposed.

Faultanalysis of Short Circuit Between Pieces of Large Motor Stator Cores

open access: yesJournal of Harbin University of Science and Technology, 2020
In order to analyze the short circuit fault between the stator core pieces of large motors, the establishment of the fault model was studied. According to the homogenization theory, the shortcircuit fault model between iron cores is studied.

New combined model of high impedance arcing fault in overhead transmission system [PDF]

open access: yes, 2012
High impedance fault is a popular complex phenomenon that exhibits high nonlinear behavior. For most distinctive characteristics of high impedance fault, are asymmetry and nonlinearity, so, in order to obtain an accurate model of high impedance fault, it

Dynamic Analysis Method for Fault Propagation Behaviour of Machining Centres

open access: yesApplied Sciences, 2021
Fault propagation behaviour analysis is the basis of fault diagnosis and health maintenance. Traditional fault propagation studies are mostly based on a priori knowledge of a causality model combined with rule-based reasoning, disregarding the ...

An Effective EMTR-Based High-Impedance Fault Location Method for Transmission Lines

open access: yes, 2020
This paper summarizes the electromagnetic time reversal (EMTR) technique for fault location, and further numerically validates its effectiveness when the fault impedance is negligible. In addition, a specific EMTR model considering the fault impedance is
