In high speed application requiring field weakening operation, iron losses could be really significant and have several origins: the frequency linked to the speed and the flux density waveform in the iron. In field weakening operation, the fundamental of flux densities waveforms decreases and could have a mitigating effect on the iron losses. However the harmonic content increases too and could have...
Under the new technical condition, the promotion of equipment complexity and high-tech features makes a significant increase in the workload of equipment support. Commands of support organizations become more complex. In order to meet these demands, the equipment support system has gradually evolved to the network structure. Network-centric equipment support system will become the development trend...
NiCu is one of the widely used thin-film materials, which is now commonly used as sensor and resistor in very-large-scale-integration (VLSI) because of its high resistivity and stability. However, with the scale decreasing and the temperature increasing in service condition, the limited reliability of NiCu thin-film material has been a key issue in microelectronics and packaging industry mainly due...
We report on advanced full-wave techniques, both in the frequency and energy domains, aimed at the investigation of the combined electromagnetic-coherent transport problem in pristine graphene, as well as in some 2D-materials beyond graphene, with particular attention to buckleld silicene.
In this article, based on grey relational analysis method, relational polarity analysis for the anti-respiratory syncytial virus effect of compositions from Baikal skullcap root was studied. The compositions with reinforcement effect on the therapeutic index of anti-respiratory syncytial virus were found and ranked.
Pollen tube growth is an essential part of the sexual reproductive process in plants. It is the result of a complex interaction of cytoplasmic contents (proteins, ions, cellular structures, etc.). Existing pollen tube models use differential equations to represent these complex intra-cellular interactions that lead to growth. As a result of this complex nature, these models are not used to verify...

We have developed a new algorithm of uncertainty analyses for the permittivity calculation of high-loss materials using the Transmission/Reflection (T/R) method. In the T/R method, there are several calculation procedures to derive the permittivity. In our method, the permittivity is derived from measured S-parameters by solving an equation in which S-parameters are included by the form: (S21+S12)+β(S...
The very fast variations on the real propagation conditions for electromagnetic waves can be simulated by a plasma sandwich model consistent in three iterated plasma layers: unmagnetized-magnetized-unmagnetized, in which we can establish resonant conditions (left-hand material conditions) by tuning the magnetization and electric potential intensity. In this paper we show how to prevent drastically...
A multi-physics model is developed based on P2D model, including the electrochemical part, thermal part and the temperature distribution.

Space charge accumulation in dielectrics is a hot topic among dielectric research group for more than a decade. The charge accumulation has been observed to be of various types like homo, hetero and packet charge, etc. Volume resistivity and its non-uniform distribution has been suspected for formation of space charge. The author has recently shown that apart from volume resistivity, diffusion coefficient...
