최근 좀 더 우수한 조타성능을 요구하는 특수목적선박의 수요가 증가하고 있고, 조종선응 향상과 관련하여 조타성능은 매우 중요한 요소이다. 이 연구에서는 여러가지 특수타 중 flap rudder의 조타성능에 관한 내용을 파악하기 위하여 flap rudder 모형을 제작하여 실험을 수행하였고, 플랩각에 따른 항력 및 양력의 변화를 분석하였다.

Analytical potential energy surfaces have been constructed for the four-center elimination of HCI from 1,1-dichloroethylene.The potential functions are Morse-type functions which are modified by appropriate switching and attenuating functions with adjustable parameters. The parameters have been found by fitting the calculated vibrational frequencies, reaction endothermicity, equlibrium geometries of the reactant and products to those of experiments and ab initio calculations. The translational energy release obtained from classical trajectory calculations on this surface is in good agreement with the experiment.

A plane wave expansion method (PWEM) was applied for photonic band structure calculation. We examined zero group velocity modes in photonic crystal. The zero group velocity modes were obtained at the second band along F-K direction. We expanded higher order Brillouin zone (BZ) to find the locations of zero group velocity modes and to investicate their properties. We found twelve locations, inside the first Brillouin zone, where the group velocities became zero. Also, we calculated band structure and group velocity in off-plane configuration.

Photonic crystal is dielectric materials or a set of different dielectric materials with periodic structure. Line defect is obtained by leaving out a row of rods along the $\Gamma$-X direction. We showed the change of group velocity in waveguide mode and found resultant small group velocity. Characteristics of the small group velocity were described by electric field distribution. Investigating the phase shift, it is confirmed if small group velocity is positive or negative.

최근 실측 데이터를 이용한 측정기반의 부하모델링이 활발히 연구되고 있다. 본 논문에서는 교내에 설치된 PMU를 이용하여 취득된 데이터를 이용하여 정적 부하모델링을 수행한 결과를 보인다. 정적부하모델링에는 ZIP모델링이 사용되었으며, 고려대학교 주배전실의 22.9kV 부하단 취득 데이터를 사용하였다. 파라미터 추정기법은 최소제곱법(Least Square Method)을 적용하였다.
