  • In this paper, we study the non-existence of finite order entire solutions of nonlinear differential-difference of the form $$f^n+Q(z,f)=h$$, where $n{\geq}2$ is an integer, $Q(z,f)$ is a differential-difference polynomial in $f$ with polynomial coefficients, and $h$ is a meromorphic function of order ${\leq}1$.

  • 전압형 HVDC(High Voltage Direct Current)는 현재 차세대 전력망으로써 각광을 받고 있고 그에 대한 연구가 활발하게 진행 중이다. 많은 논문에서 모듈형 멀티레벨 컨버터(Modular Multilevel Converter, MMC)의 제어 및 보호 방안에 대하여 기술하지만 운영적인 시퀀스 측면에 있어서는 아직 많은 연구가 진행되지 않고 있다. 이에 본 논문은 전압형 HVDC의 AC Yard, DC Yard 및 상위 제어기에 관한 구동 시퀀스에 대하여 기술하고자 한다.

  • One novel electrode-architecture has been adapted to fabricate transparent OTFTs. The device has more than 70% transmittance, yet reminds high performance. Furthermore, we also use transfer line method to prove that the device performance enhancement indeed contributes from the reduction of the contact resistances. It is anticipated that the transparent OTFTs would be very suitable to be the driving circuits for liquid crystal displays (LCDs).
