Continuous wavelet transform for ferroresonance phenomena in electric power systems
(Elsevier Sci Ltd, 2013)
The common characteristics of a nonlinear system are multiple equilibrium points, limit cycles, jump resonance and sub-harmonic generation. Ferroresonance is also a nonlinear electrical phenomenon, which occurs frequently ...
System of Power Supply and Oscillating Pulse Current Synchronous Drive in Power Network
(Ieee, 2014)
There are a number of electrical drives with oscillatory driven mechanisms. As a result it is possible to use oscillating movement electrical drives there. These drives create ineligible reactive power, therefore it is ...
Speed Estimation of Brushless Direct Current (BLDC) Motor with Multilayer Perceptron
(Wydawnictwo Sigma-N O T Sp Z O O, 2012)
This study used an artificial neural network model to estimate the revolutions per minute of a brushless direct current (BLDC) motor operating at different driver modes and different load currents. The dataset that was ...
Spectral and Statistical Analysis for Ceramic Plate Specimens Subjected to Impact
(Trans Tech Publications Ltd, 2013)
In this study, ceramic plate behaviour was elaborated on the basis at sound signal variations caused by the impact. All tests were performed using plate specimens and pendulum testing station; with date acquisition and ...
The defect detection in ceramic materials based on wavelet analysis by using the method of impulse noise
(Jve Int Ltd, 2013)
In this experimental study, it was achieved to detect internal or surface cracks that can occur in the production of ceramic plates by using the method of impulse noise. This method is a test technique which was not used ...
A neuro-detector based on the cybernetic concepts for fault detection in electric motors
(Jve Int Ltd, 2011)
In this study, an auto-associative neural network (AANN) is designed as a fault detector using the cybernetic concepts. In this sense, an artificial neural network structure is connected with a finite state system or a ...
Statistical Analysis and Hurst Parameter Estimation for Wind Speed in Kirklareli Area of Turkey
(Ieee, 2013)
In this study, a wind speed data of the Klrklareli region of Turkey is considered and Hurst parameter is calculated for this data. For this purpose at first statistical parameters of the wind speed data are calculated. ...
