Traction Inverter Open Switch Fault Diagnosis Based on Choi–Williams Distribution Spectral Kurtosis and Wavelet-Packet Energy Shannon Entropy

open access: yesEntropy, 2017
In this paper, a new approach for fault detection and location of open switch faults in the closed-loop inverter fed vector controlled drives of Electric Multiple Units is proposed.

Suspension-to-suspension justification principles [PDF]

open access: yesBelgrade Philosophical Annual, 2020
We will be in a better position to evaluate some important skeptical theses if we first investigate two questions about justified suspended judgment. One question is this: when, if ever, does one justified suspension confer justification on another suspension? and the other is this: what is the structure of justified suspension?

Interaction Between Gravity Compensation Suspension System and Deployable Structure [PDF]

open access: yes, 2000
Gravity compensation suspension systems are essential to support space structures during tests on Earth, but also impose constraints on the structures that have the effect of changing their behavior.

Wavelet Entropy-Based Traction Inverter Open Switch Fault Diagnosis in High-Speed Railways

open access: yesEntropy, 2016
In this paper, a diagnosis plan is proposed to settle the detection and isolation problem of open switch faults in high-speed railway traction system traction inverters.

Quantification of solid particle transport in suspension in a stream: Case of Wadi Zeddine Ain-Defla, Algeria [PDF]

open access: yesJournal of Water and Land Development, 2023
Arid and semi-arid areas are characterised by differentiation in meteorological conditions. Sometimes the rains are rare and not very intense and at other times they are dense and very intense, resulting in torrents that often lead to strong soil erosion.

H ∞ and μ-synthesis Design of Quarter Car Active Suspension System [PDF]

open access: yes, 2020
To improve the street managing and passenger comfort of a vehicle, a suspension system is furnished. An active suspension device is considered to be better than the passive suspension device.

Semi-active suspension systems from research to mass-market – A review

open access: yesJournal of Low Frequency Noise Vibration and Active Control, 2019
It is well documented that active suspension systems offer substantial benefits in ride comfort, handling control over traditional passive systems. However, restrictive features such as the power required and costs make an active system impractical.

Diffusion Signed LMS Algorithms and Their Performance Analyses for Cyclostationary White Gaussian Inputs

open access: yesIEEE Access, 2017
As one of the signed variants of the diffusion least mean square (DLMS) algorithm over networks, the diffusion sign error algorithm has been presented in previous reference. In this paper, we propose two novel signed variants of the DLMS algorithm, i.e.,

Optimal design of a for middle-low-speed maglev trains

open access: yesOpen Physics, 2018
A middle-low-speed maglev train is supported by an electromagnetic force between the suspension electromagnet (EM) and the steel rail and is driven by a linear induction motor.
