A New Method for Detection and Evaluation of Winding Mechanical Faults in Transformer through Transfer Function Measurements

open access: yesAdvances in Electrical and Computer Engineering, 2011
Transfer function (TF) is an acknowledged method for power transformer mechanical faults detection. However the past published works mostly discovered how to specify the faults levels and paid less attention to detection of the type of faults using ...

Prediction and Sound Quality Analysis of Tire Pattern Noise Based on System Identification by Utilizing an Optimal Adaptive Filter

open access: yesApplied Sciences, 2019
Identifying the cause of vehicle noise is a basic requirement for the development of low-noise vehicles. The tire pattern noise depends on the tire itself and causes complex and unpredictable sounds.

Structural-Parametric Model of Electromagnetoelastic Actuator for Nanomechanics

open access: yesActuators, 2018
The generalized parametric structural schematic diagram, the generalized structural-parametric model, and the generalized matrix transfer function of an electromagnetoelastic actuator with output parameters displacements are determined by solving the ...

A Matrix Approach for Analyzing Signal Flow Graph

open access: yesInformation, 2020
Mason’s gain formula can grow factorially because of growth in the enumeration of paths in a directed graph. Each of the (n − 2)! permutation of the intermediate vertices includes a path between input and output nodes.

On determining which quantum measurement performs better for state estimation

open access: yes, 2014
We introduce an operational and statistically meaningful measure, the quantum tomographic transfer function, that possesses important physical invariance properties for judging whether a given informationally complete quantum measurement performs better ...

Analysis of double-parallel amplified recirculating optical-delay lines [PDF]

open access: yes, 1994
A novel method of analysis of double-parallel amplified recirculating optical-delay lines (DPAROD) is presented. The location of the maxima and the minima of the transfer function for this configuration is calculated and experimentally demonstrated.

Mueller Matrix Parameters for Radio Telescopes and their Observational Determination [PDF]

open access: yes, 2001
Modern digital crosscorrelators permit the simultaneous measurement of all four Stokes parameters. However, the results must be calibrated to correct for the polarization transfer function of the receiving system. The transfer function for any device can

Limits on the amplification of evanescent waves of left-handed materials

open access: yes, 2005
We investigate the transfer function of the discretized perfect lens in finite-difference time-domain (FDTD) and transfer matrix (TMM) simulations; the latter allow to eliminate the problems associated with the explicit time dependence in FDTD ...
