Magnetic levitation refers to the object using electromagnetic force to overcome gravity and achieve a stable suspension or random equilibrium state without mechanical contact.
This paper presents a double-ladders circuit model of transformer winding for use in frequency response analysis (FRA) to diagnose the windings deformation. This model considers the nonlinear behavior of frequency-dependent parameter and core loss. A lumped parameter circuit model includes the axial and radial ladder network which are regarding to the winding discs and the eddy current paths of magnetic...
Magnetic encoders comprise a magneto-resistive sensor and a multi-pole magnetic scale. They are applicable under a harsh environment. The purpose of this study is to design and fabricate high quality magnetic remanence, both field strength and waveform, out of a magnetic scale aiming to a great improvement in resolution. However, magnetization study of multi-pole magnetic scale is few. Some factors...
Future wireless systems have been evolving toward a broadband and open architecture for efficient multi-service operation, which will have a great impact on the terminal and infrastructure component design methodology for supporting multiple radio schemes. Cooperation in wireless networks, requiring cognitive radio implementations, will facilitate a new dimension in the evolution of multimedia communications...
