Design and application of a novel snubber cell for soft switched pwm dc–dc converters
(Springer, 2019)
This paper introduces a novel active snubber cell for soft switching PWM DC–DC converters. In the proposed converter, the main switch is turned on under zero voltage transition (ZVT) and turned off under zero voltage ...
An application of the Sonine–Letnikov fractional derivative for the radial schrödinger equation
(MDPI AG, 2019)
The Sonine–Letnikov fractional derivative provides the generalized Leibniz rule and, some singular differential equations with integer order can be transformed into the fractional differential equations. The solutions of ...
Microscopic analysis of elastic scattering cross sections for different densities of 8Li nucleus on light, medium and heavy mass targets
(Sociedad Mexicana de Fisica, 2019)
The elastic scattering angular distributions of the weakly bound nucleus 8Li on 7Li, 9Be, 12C, 13C, 14N, 27Al, 51V, 58Ni, and 208Pb are analyzed at various incident energies. For this purpose, the real potential is generated ...
Volatility measurement of the world indices using different entropy methods
(Serbian Society of Heat Transfer Engineers, 2019)
In this paper, we show that the application of different entropy methods for world indices. To do this, we use the world indices such as Istanbul Stock Indices (BIST 30), Brazil Index (Bovespa), Germany Index (DAX), Britain ...
Entropy approach for volatility of wind energy
(Serbian Society of Heat Transfer Engineers, 2019)
In this study, we give the practice of entropy in wind energy. Firstly, we fit marginal distributions to each of the variables and later demonstrate the notion of entropy to perform a comparison the wind energy data of the ...
Determination of urban earthquake risk for kırşehir, Turkey [Determinación del riesgo urbano en caso de un terremoto en kirsehir, Turquía]
(Universidad Nacional de Colombia, 2019)
Predicting the outcomes of earthquakes before they occur is one of the fundamental components of modern disaster management. Loss estimation analyses have an important place at the assessment stage of earthquakes and in ...
The effects of nitric oxide on some antioxidant enzyme activities under salt stress in sunflower plants
(Wydawnictwo Akad Rolniczej W Lublinie, 2019)
The effects of externally applied sodium nitroprusside on superoxide dismutase (SOD), glutathione peroxidase (GPx), ascorbate peroxidase (APX), and catalase (CAT) antioxidant enzyme activities, nitric oxide (NO) levels ...
Landscape heritage at Çadir höyük: From cartography to digital imagery
(Penn State University Press, 2019)
Studies of archaeological cultural heritage typically focus on sites and landscapes threatened by military conflict, while threats from development and urban expansion are often more common. Excavations at Çadır Höyük began ...
A python tool for implementations on bipolar neutrosophic matrices
(University of New Mexico, 2019)
Bipolar neutrosophic matrices (BNM) are obtained by bipolar neutrosophic sets. Each bipolar neutrosophic number represents an element of the matrix. The matrices are representable multi-dimensional arrays (3D arrays). The ...
The effect of the aging time on microstructure and mechanical properties of the AA7075 alloy after T6 heat treatment
(G.V. Kurdyumov Institute for Metal Physics of N.A.S. of Ukraine, 2019)
In this study, the effect of the aging time on microstructure and mechanical properties of the AA7075 alloy after T6 heat treatment is investigated. The AA7075 alloys are quenched after solid solution treatment at 485°C ...
