Mtissbauer measurement, chemical analysis (ratioof Fez+ to total Fe content), analyses ofthe rotational hysteresis loss (Wr) and the magnetic viscosity coefficient (Sv) for bacterial magnetic particles covered with organic thin films (BMPs) were investigated and compared with the results for Fes04 h e particles prepared by a chemical coprecipitation method. The calculated value of the saturatio...

-This paper details the electromagnetic behavior and the effects of magnetic and electromagnetic shields used in large power transformers based on engineering-oriented benchmark models, and presents some newly calculated and measured results both the magnetic field and stray-field loss related to the models, and examine the engineering applicability of 3-D eddy current analysis methods and the ...

We deal with a cost-based adaptive handover hysteresis scheme for the horizontal handover decision strategies, as one of the selfoptimization techniques that canminimize the handover failure rate (HFR) in the 3rd generation partnership project (3GPP) longterm evolution (LTE) system based on the network-controlled hard handover. Especially, for real-time operation, we propose an adaptive hystere...

This paper presents the design of neural networks compared with the conventional technique, a hysteresis controller for active power filter for three-phase four-wire electric system. A particular three-layer neural network structure is studied in some detail. Simulation and experimental results of the active power filter with both controllers are also presented to verify the feasibility of such...

We investigate the dissipative loss in the ±J Ising spin glass in three dimensions through the scaling of the hysteresis area, for a maximum magnetic field that is equal to the saturation field. We perform a systematic analysis for the whole range of the bond randomness as a function of the sweep rate by means of frustration-preserving hard-spin mean-field theory. Data collapse within the entir...
