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 ...
ENVIRONMENTAL ASSESSMENT OF WIND ENERGY CONVERSION SYSTEMS IN TURKEY
(Scibulcom Ltd, 2012)
Nowadays, approximation of fossil-based fuel to exhaustion reveals that countries will have difficulty in meeting energy needs in the near future. Renewable energy sources are prognosed as a solution to this problem. Among ...
Effects of Thermal Annealing and Film Thickness on the Structural and Morphological Properties of Titanium Dioxide Films
(Polish Acad Sciences Inst Physics, 2012)
Titanium dioxide (TiO2) thin films having different thicknesses of 220, 260, and 300 nm were deposited onto well-cleaned n-type silicon substrates by reactive DC magnetron sputtering and annealed in the range of 200-1000 ...
Application of wavelet transform to defect detection of building's structure
(Kaunas Univ Technol, 2012)
Various methods can be used to detect the defects of structures. In this paper wavelet transform method is used. Continuous wavelet transform (CWT) is applied to vibration signal analysis of building's construction with ...

The beginning of the 18 th centuy is a tuning point for the Ottoman Empire. Because, in this century there were major changes in the Empire. Militaq defeats caused inquily of the militaq training of Ottomam, as a result ...
10 kW grid-connected three-phase inverter system: Control, simulation and experimental results
(2012)
In this study, implementation of a 10kW three-phase grid-connected inverter system is discussed. The system includes a high voltage dc-link, a two-level inverter and filter inductances. The high voltage dc-link is obtained ...
The comparative analysis of boost DC/DC converter used in hybrid electric vehicles
(2012)
Power electronics converters are the periodically changing systems because of their switching structures. For this reason, the dynamic attitudes of the converters show nonlinear characteristics. The analysis and design of ...
Application of Artificial Neural Networks for Defect Detection in Ceramic Materials
(Polska Akad Nauk, Polish Acad Sciences, Inst Fundamental Tech Res Pas, 2012)
In this study, an artificial neural network application was performed to tell if 18 plates of the same material in different shapes and sizes were cracked or not. The cracks in the cracked plates were of different depth ...
Nutritional management of metabolic syndrome in children
(2012)
The metabolic syndrome is defined as the presence of at least three of the following criteria: central or abdominal obesity, hypertrglyceridemia, hypertension, low HDL cholesterol and high fasting glucose levels in an ...
The application of instantaneous reactive power calculation methods to a real power system
(Sila Science, 2012)
