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 ...
Determination of Quercetin in Medicinal Plants Such as Rose Hip (Rosa canina), Bettle (Urtica dioica), Terebinth (Terebinthina chica) and Purslane (Portulace oleracea) using HPLC-MS Method
(Asian Journal Of Chemistry, 2012)
A simple and rapid high performance liquid chromatography-mass spectrometry (HPLC-MS) method was developed for the determination of quercetin in four plants and fruits samples which are rose hip (Rosa canina), nettle (Urtica ...
Current-voltage (I-V) characteristics of Au/InGaAs/n-GaAs Schottky barrier diodes
(Natl Inst Optoelectronics, 2012)
In this study, the forward and reverse bias current-voltage (I-V) characteristics of Au/InGaAs/n-GaAs Schottky barrier diodes (SBDs) have been investigated at room temperature. InGaAs epilayer was grown on (100) oriented ...
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 ...
The application of instantaneous reactive power calculation methods to a real power system
(Sila Science, 2012)
Many calculation methods have been developed to calculate the reactive power used in energy transmission lines. In this study; preferred instantaneous power calculation techniques such as instantaneous orthogonal currents, ...
Coherence analysis between hydrogen flow and electricity current in fuel cells
(Sila Science, 2012)
In this study the spectral properties of the hydrogen flow and electricity current data which are collected from a fuel cell system are extracted. The electricity current of the fuel cell system is in the DC character ...
Early warning systems for currency crises: The Turkish case
(Elsevier, 2012)
Different severe financial crises episodes occurred in the Turkish economy in the last two decades. These crises led to severe economic and social consequences for Turkey in terms of increasing interest rates, large reserves ...
The influence of thickness and ammonia flow rate on the properties of AlN layers
(Elsevier Sci Ltd, 2012)
Undoped AlN layers have been grown on c-plane sapphire substrates by metal-organic chemical vapor deposition in order to study the effects of ammonia (NH3) flow rate and layer thickness on the structural quality and surface ...
Thermal behaviors of N-pyrrolidine-N '-(2-chlorobenzoyl)thiourea and its Ni(II), Cu(II), and Co(III) complexes
(Springer, 2012)
The N-pyrrolidine-N'-(2-chlorobenzoyl)thiourea, HL, and their Ni(II), Cu(II), and Co(III) complexes (NiL2, CuL2, and CoL3) have been synthesized and characterized. The thermal decomposition reactions of all the compounds ...
The relationship of subjective global assessment with respiratory function and other nutrition parameters in COPD
(Drunpp-Sarajevo, 2012)
Background and purpose: Malnutrition, weight loss and low body mass in COPD (Chronic obstructive pulmonary disease) are independent and negative risk factors regarding the survival of these patients. Malnutrition may lead ...
