Investigation of The Effect of Temperature on The Structural and Magnetic Properties of MgB2 Superconductor Produced Using Boron Doped with Carbon by CVD Method
(Gazi Üniversitesi, 2021)
Carbon, which is known to play a improvement role on the superconductivity properties of MgB2, was doped into MgB2 by CVD (chemical vapor deposition) method, and the change of structural and magnetic properties observed ...
Windowed Scalogram Entropy: Wavelet-Based Tool to Analyze the Temporal Change of Entropy of a Time Series
(Springer, 2021)
In this paper, we propose a new entropy calculation method to observe the temporal change of the entropy of dynamical systems. The proposed entropy calculation method is based on the windowed scalogram which has been ...
Toward Class AAA LED Large Scale Solar Simulator with Active Cooling System for PV Module Tests
(IEEE Electron Devices Society, 2022)
Solar simulators are significant in testing solar cells and photovoltaic (PV) modules since they provide spectrum and optic characteristics close to natural sunlight. This research introduces two fundamental novelties to ...
Chronology of trace elements and radionuclides using sediment cores in Golden Horn Estuary, Sea of Marmara
(Elsevier Ltd, 2022)
Trace elements and radionuclides are substantial pollutants in marine environment since they are non-biodegradable and can be harmful even in minute concentrations. The Golden Horn estuary, where is an inlet of Bosphorus ...
Entropy of the quantum fluctuations of fermionic instantons in the Universe
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2022)
The aim of this paper is to study the entropy of quantum fluctuations of fermionic instantons. For this purpose, we focus on the spinor-type instanton solution family of the massless pure fermionic Thirring model because ...
Prediction of Wind Speed Using Artificial Neural Networks and ANFIS Methods (Observation Buoy Example)
(Institute of Electrical and Electronics Engineers Inc., 2020)
Estimation of the wind speed plays an important role in many issues such as route determination of ships, efficient use of wind roses, and correct planning of agricultural activities. In this study, wind velocity estimation ...
Development of a deep wavelet pyramid scene parsing semantic segmentation network for scene perception in indoor environments
(Springer Science and Business Media Deutschland GmbH, 2022)
In this paper, a new Deep Wavelet Pyramid Scene Parsing Network (DW-PSPNet) is proposed as an effective combination of Discrete Wavelet Transform (DWT), inception module, the channel and spatial attention modules, and ...
The 'wavelet' entropic index q of non-extensive statistical mechanics and superstatistics
(Elsevier Ltd, 2021)
Generalized entropies developed for non-extensive statistical mechanics are derived from the Boltzmann-Gibbs-Shannon entropy by a real number q that is a parameter based on q-calculus; where q is called ‘the entropic index’ ...
