Heuristic algorithm-based estimation of rotor resistance of an induction machine by slot parameters with experimental veri cation
(2017)
The estimations of induction machine equivalent circuit parameters are still being widely used in the analysis and in determining the characteristics of the machine. Since the most important part of the machine is the rotor ...
Low-cost multimode diode-pumped Tm:YAG and Tm:LuAG lasers
(2019)
We report a continuous-wave operation of Tm:YAG and Tm:LuAG lasers pumped with a low-cost, multimode AlGaAs laser diode. First, the lifetime and the absorbance behavior of 5 mm, 6% Tm3+ -doped YAG and LuAG crystals were ...
Optical and structural properties of bismuth doped ZnO thin films by sol-gel method: urbach rule as a function of crystal defects
(Polish Acad Sciences Inst Physics, 2014)
Bismuth (Bi) doped zinc oxide (ZnO:Bi) thin films were prepared on glass substrates by sol gel spin coating technique using homogeneous precursor solutions, and effects of Bi doping on the structural and optical properties ...
Design of wave energy converter system with linear generator
(Polish Acad Sciences Inst Physics, 2015)
It is not wrong to say that wave energy will be one of the most important energy sources to be used in the future, when it is thought that three-quarters of the world is covered by water. the initial investment and maintenance ...
The effect of fluorine and tungsten co-doping on optical, electrical and structural properties of tin(IV) oxide thin films prepared by sol-gel spin coating method
(Technical Univ Wroclaw, 2013)
Fluorine and tungsten co-doped tin(IV) oxide (WFTO) thin films have been prepared first time by a sol gel spin coating method. the effect of F and W co-dopant ratio on optical, electrical and structural properties of SnO2 ...
Comparison of reduction methods for peak-to-average-power-ratio (PAPR) in MIMO-OFDM systems with a new approach
(Polish Acad Sciences Inst Physics, 2016)
This study is based on the comparison of the results of an analysis recommended for the peak-to-average-power-ratio (PAPR) reduction methods. This is one of the most significant problems in the multiple input-multiple ...
Olfaction recognition by EEG analysis using wavelet transform features
(Ieee, 2016)
The responses of the brain into different information coming from sense organs could be analyzed by various kinds of measuring techniques. Among the existing techniques, Electroencephalography (EEG) is widely used because ...
A new wide area-based algorithm to determine faulted line in series-compensated grid using k-nearest neighbor (k-NN) classification method
(Gazi Üniversitesi Mühendislik Mimarlık Fakültesi, 2021)
Nowadays, series capacitors are frequently used to increase the transfer capacity and reduce losses on long transmission lines. They also play an important role in improving the voltage stability of the grid. In addition ...
A comprehensive review on supercapacitor applications and developments
(MDPI, 2022)
The storage of enormous energies is a significant challenge for electrical generation. Researchers have studied energy storage methods and increased efficiency for many years. In recent years, researchers have been exploring ...
Performance assessment of solar chimney power plants with natural thermal energy storage materials on ground: CFD analysis with experimental validation
