  • In this paper, proposed a multi-channel charging control strategy for electric vehicle. This control strategy can adjust the charging power according to the calculated state-of-charge (SOC). Electric vehicle (EV) charging system using Particle Swarm Optimization (PSO) algorithm is proposed. A stochastic optimization algorithm technique such as PSO in the time-of-use (TOU) price used for the energy cost minimization. Simulation results show that the energy cost can be reduced using proposed method.

  • Using the computer-generated Lyapunov functions due to Brayton-tong's constructive algorithm, we estimate the domains of attraction of dynamical systems of the second order, and analyze the asymptotic stability of large scale contincous-time and discrete-time systems by the decomposition and aggregation method. With this approach we get the less conservative stability results than the existing methods.

  • This study analyzed a costume historic meaning of TANGUN Mythology. TANGUN Mythology have been transmitted from many literatures but TANGUN Mythology recorded Samgukyusa(II-Yun) is not false piece or a fiction. A Costume historic meaning of TANGUN Mythology was studied in the clothing system meaning of a headgear worn by nobles in court in the Chun-Boo-In three and meaning of bear and tiger. However results are not clear. In addition the Han stones of Wu Liang Tz'u relates to TANGUN Mythology but results also are not manifest.
