This paper describes the calculation of the magnetic shielding effectiveness in current comparators, considering the air gap which is inevitable for the magnetic shielding. The method was verified to be accurate and effective by finite-element method analysis. Experiments were implemented to investigate the effect of the air gap as well.
This paper deals with a nonlinear parabolic equation with a complicated source term, which is a product of localized source $e^{q u(0,t)}$, local source $e^{pu(x, t)}$, and weight function $a(x)$. We investigate how the three factors influence the asymptotic behavior of solutions. We show that the blow-up set consists of single point if $p>0$; when with $p+q>0$, the blow-up takes...
Non-linear editing is a revolutionary leap on the techniques of TV programs designing, fully demonstrated the industry including the latest digital technology, computer technology, but it is also a new technology of constantly developing and upgrading and have strong vitality, on the television program designing, it will fully demonstrate the superiority. Through studying the use of the Nonlinear...
Optical mark recognition (OMR) is a traditional data input technique and an important human computer interaction technique which is widely used in education testing. Aimed at the drawbacks of current OMR technique, a new image-based low cost OMR technique is presented in the paper. The new technique is capable of processing thin papers and low-printing precision answer sheets. The system key techniques...
