Comparative study of critical current density, pinning force and levitation force behavior in Yb211 doped-Sm123 bulk superconductors
(ELSEVIER SCIENCE SA, PO BOX 564, 1001 LAUSANNE, SWITZERLAND, 2012-04-15)
The effect of Yb211 doping on the critical transition temperature (T-c), c-lattice parameter, critical current density (J(c)), volume pinning force (F-p) and the vertical levitation force density properties of MPMG-processed ...
Comparison of levitation force relative to thickness of disk shaped YBa2Cu3O7-x prepared by MPMG and FQMG processes
(ELSEVIER SCIENCE SA, PO BOX 564, 1001 LAUSANNE, SWITZERLAND, 2009-11-20)
The precursor YBCO in the stoichiometric ratio of 1:23 were fabricated using the melt-powder-melt-growth (MPMG) technique, and flame-quench-melt-growth (FQMG) technique. The superconducting regions were determined by ...
AC loss study by AC susceptibility measurement in a commercial Bi:2223/Ag tape prepared by the CTFF method: H // c axis and short specimen
(IOP PUBLISHING LTD, DIRAC HOUSE, TEMPLE BACK, BRISTOL BS1 6BE, ENGLAND, 2009-12-23)
The effect of temperature, field amplitude, frequency and orientation of the field on AC losses in a commercial Bi:2223/Ag tape prepared by the continuous filling and forming (CTFF) method has been investigated. The ...
AC losses in commercial Bi:2223/Ag tape
(IOP PUBLISHING LTD, DIRAC HOUSE, TEMPLE BACK, BRISTOL BS1 6BE, ENGLAND, 2009-02-17)
We have investigated the effect of temperature, field amplitude, frequency and orientation of the field on AC losses in a commercial Bi:2223/Ag tape. The measurements were performed using an AC susceptometer. The experimental ...
AC losses and determination of some superconducting parameters of Ag2O added Bi2223 superconductors
(ELSEVIER SCIENCE BV, PO BOX 211, 1000 AE AMSTERDAM, NETHERLANDS, 2006-04-15)
The effects of Ag2O addition on electromagnetic properties in a Bi2223 superconductor have been investigated by means of AC susceptibility measurements and theoretical analysis. Intergranular critical current density was ...
The Aporias of constitutionalism: the question of constituent power and democracy
(European Journal of Research on Education, 2014)
This article discusses the paradox between democracy and constitution. It emphasizes to think constitutional amendment as a political problem not only a juridical issue. It first highlights some approaches to the problem ...
Seismic b-Values, Bouguer Gravity and Heat Flow Data Beneath Eastern Anatolia, Turkey: Tectonic Implications
(Springer, 2015)
In this paper, we analyze the relationships between the seismic b-values, Bouguer gravity and heat flow data in the Eastern Anatolia region of Turkey. For this purpose, spatial distributions of b-value, Bouguer gravity and ...
Stochastic finite element analysis of a cable-stayed bridge system with varying material properties
(Elsevier Sci Ltd, 2010)
Stochastic seismic finite element analysis of a cable-stayed bridge whose material properties are described by random fields is presented in this paper. The stochastic perturbation technique and Monte Carlo simulation (MCS) ...
