The present paper deals with a new approach for the study of the steady - state and transient behaviour of three- phase transformers. This approach based on magnetic equivalent circuit diagrams, takes into account the nonlinear B-H curve as well as zero-se ...
This paper presents results from numerical modelling of non-twisted multifilamentary Bi-2223/Ag conductors with various geometry and filament arrangement. New anisotropic models of Jc(B) and n(B) have been employed in finite element method simulations unde ...
This paper describes quantitatively the influence of the self-field and the cross-sectional geometry on the effective critical current and the ac losses in transport current applications of non-twisted multifilamentary Bi-2223/Ag conductors. The results ar ...
This article discusses neutron scattering measurements on the cuprate, high transition temperature superconductor La2-xSrxCuO4 (LSCO) in an applied magnetic field. LSCO is a type-II superconductor and magnetic flux can penetrate the material via the format ...
The possibility of fulfilling the condition of poloidal closure of the contours of the second adiabatic invariant for all reflected particles is studied for systems with poloidally closed contours of the magnetic field B on the magnetic surfaces through co ...
We have measured the magnetization of a two-dimensional electron system that has been laterally patterned to an array of mesoscopic dots. In our experimental data we observe sawtooth-like de Haas–van Alphen (dHvA) oscillations of the equilibrium magnetizat ...
The present dissertation considers the capabilities, limitations and possible extensions of modelling the hysteresis that is exhibited by type-II superconductors, especially those with high critical temperature. Superconductors of type-II, including high t ...
Superconductors of type-II are partially penetrated by magnetic flux, where the pinning of flux tubes constitutes a memory that gives rise to a hysteresis. However, the hysteresis gradually disappears when a transport current approaches the critical curren ...
The Retarding Field Analyser (REA) is essentially the only practical tool for the measurement of ion energies parallel to the total magnetic field in the tokamak scrape-off layer plasma. One such device has recently been successfully employed at JET [1]. I ...
In this study, we examine the parameters that govern the overall oxygen flux through a permeation membrane. The chemical diffusion (D) and the surface exchange (k) coefficients for oxygen in La0.6Sr0.4Fe0.8Co0.2O3-d were determined as a function of tempera ...
