When the lateral inter-laminar fault occurs on silicon steel laminations, simulation of laminated core with conventional finite element method could be time-consuming considering specific structure model. Thus, we proposed a 1D-2D homogenization equivalent electrical conductivity eddy currents side to save computing costs. For experimental verification, edge burrs are represented by artificial faults lead-free solder lamination. With method, iron losses can calculated accurately compared...
The moving and fixed coordinate systems for eddy current analysis with conductors are examined compared. It is shown that the system superior transient from standpoints of accuracy, computer storage, CPU time. In DC steady state large Peclet number, spurious oscillations occur when using ordinary Galerkin finite element method. solution system, however, can be obtained stably.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Computer codes developed for the A- phi , - Omega T- and E- methods are considered. Their accuracy, storage requirements, CPU time compared linear eddy-current models. It is shown that preferable from viewpoint of accuracy. The with respect to time.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
To establish a large-scale magnetic field analysis, the analysis with voxel modeling is investigated. reduce number of elements, nonconforming technique introduced. The accuracy flux densities, eddy current and forces obtained from verified by comparing those ordinary in simple 2-D model. Moreover, proposed method applied to 3-D model as well nonlinear IPM motor It shown that results sometimes converge true values slowly, whereas it provides acceptable results.
The distribution of Kexin family proteases in adult rat pancreatic islets was investigated by immunohistochemical means using a series specific antibodies for PC1, PC2, PC6, Furin, PACE4A and recently identified member the family, PACE4C. PACE4C expression limited to B cells islets. PC2 found A some D more than PC1 evident only cells. Furin PC6 were weakly evenly expressed entire islet. hardly These findings indicated that individual are uniquely distributed suggested these share roles as...
The performance requirements of next-generation CMOS image sensors (CIS) have been increasing in terms frame rate, read noise, dynamic range, as well pixel resolution. In order to satisfy strict specifications, a column-parallel ADC is key element state-of-the-art CIS. However, this architecture leads side-effects such vertical fixed pattern noise (VFPN) and noise. reduce these non-idealities, several techniques can be applied digital CDS using single-slope ADC, pre-amplified SAR ADC. It...
Fault current limiter (FCL) serves as a promising solution for severe fault issues in high-voltage direct (HVdc) systems. However, the small impedance changing ratio and detecting time delay of existing HVdc system FCL topologies make them have some performance deficiencies. In this article, two-stage dc (TFCL) was proposed, which has large automatic response characteristics. can be first restricted by automatically increased inductance provided saturated core module, then limited an active...
We have measured the inclusive $D^{*\pm}$ production cross section in a two-photon collision at TRISTAN $e^+e^-$ collider. The mean $\sqrt{s}$ of collider was 57.16 GeV and integrated luminosity 150 $pb^{-1}$. differential ($d\sigma(D^{*\pm})/dP_T$) obtained $P_T$ range between 1.6 6.6 compared with theoretical predictions, such as those involving direct resolved photon processes.
In order to detect steel bars and power cables inside pliable plastic conduit tubes buried in concrete walls slabs during the renovation of old buildings, we have developed a new nondestructive inspection (NDI) system. This system, which enables high precision detection easy handling at low cost, works by measuring impedance due inductance change solenoid coil exposes test material magnetic field. this is connected compensating capacitor with series-resonant circuit reduce multiply...
