MRI reconstruction with joint global regularization and transform learning
(Pergamon-Elsevier Science Ltd, 2016)
Sparsity based regularization has been a popular approach to remedy the measurement scarcity in image reconstruction. Recently, sparsifying transforms learned from image patches have been utilized as an effective regularizer ...
Design and implementation of hydrogen economy using artificial neural network on field programmable gate array
(Pergamon-Elsevier Science Ltd, 2020)
In this study, economic analysis of the hydrogen generation and liquefaction system has been modeled using Multi-Layer Feed-Forward Artificial Neural Network (MLFFANN) and implemented on Field Programmable Gate Array (FPGA). ...
A Novel Simple 4-D Hyperchaotic System with a Saddle-Point Index-2 Equilibrium Point and Multistability: Design and FPGA-Based Applications
(Springer Birkhauser, 2020)
This paper presents a novel simple 4-D dissipative autonomous hyperchaotic system with a saddle-point index-2 equilibrium point. The dynamics of the new system consists of nine terms with two nonlinear terms. Thus, the ...
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 ...
Spectral and statistical analysis for ferroresonance phenomenon in electric power systems
(Springer, 2012)
This study presents our findings on the ferroresonance phenomenon for the Seyitomer-Isiklar part of the Electric Power System of 380 kV in Turkey. In this context, the power spectral density approach and Short-Time Fourier ...
A 5-D Multi-Stable Hyperchaotic Two-Disk Dynamo System With No Equilibrium Point: Circuit Design, FPGA Realization and Applications to TRNGs and Image Encryption
(Ieee-Inst Electrical Electronics Engineers Inc, 2021)
In this work, we devise a new 5-D hyperchaotic dynamo system by adding two feedback controllers to the Rikitake 2-disk dynamo system (1958). We show that the new 5-D hyperchaotic system does not possess any equilibrium ...
The Defect Detection in Ceramic Materials Based on Time-Frequency Analysis by Using the Method of Impulse Noise
(Polish Acad Sciences Inst Fundamental Technological Research, 2011)
In this study, it was achieved by using the method of impulse noise to detect internal or surface cracks that can occur in the production of ceramic plates. Ceramic materials are often used in the industry, especially as ...
The determination of short circuits and grounding faults in electric power systems using time-frequency analysis
(Univ Cape Town, Energy Res Centre, 2015)
In order to ensure that electrical energy reaches consumers uninterrupted, researchers constantly try to improve power transmission lines. To realize this improvement, probable faults should be analysed through every known ...
Development of 10 kW Three-Phase Grid Connected Inverter
(Korema, 2016)
In this paper, modeling, simulation and experimental study of a 10 kW three-phase grid connected inverter are presented. The mathematical model of the system is derived, and characteristic curves of the system are obtained ...
Heavy Metal Concentrations of Groundwater in the East of Ergene Basin, Turkey
(Springer, 2014)
The aim of this research was to investigate the concentrations of the heavy metals (copper, iron, zinc, chromium, cadmium and lead) and determine their relationship between pH and EC in the east of Ergene Basin, Turkey. ...
