  • The dye-resist effect of reactive dye-resist agents in reactive dyeing of silk was investigated. The dichlorotriazine-based dye-resists achieved a higher effectiveness than others since they make a charge barrier of diffusion in the silk fiber periphery due to high reactivity of dichlorotriazine group. Similarly, in the case of hetero-multifunctional dye-resist agent, the dye-resist agent containing both a dichlorotriazine and an ${\alpha}$-bromoacrylamide reactive groups achieved better resist effectiveness than those containing both a monochlorotriazine and an ${\alpha}$-bromoacrylamide groups. Also, their resist effectiveness was improved by increasing the number of sulfonate groups in the dye-resist agents and the number of reactive groups in the reactive dyes applied to them.

  • In this paper, we design the robust controller for MIMO system using multiple fuzzy logic controller. Based on the knowledge of system input/output data, we introduce the simple adaptation laws to approximate the decoupling matrix from input channel to output channel. The proposed control algorithm is applied numerical example.

  • MAC 프레임 결합 기법은 다수의 MPDU (MAC protocol data units)를 하나의 PPDU (PHY protocol data units)로 결합시켜 네트워크의 데이터 전송 효율을 높이는 방법이다. 본 논문에서는 프레임 결합 기법이 애드혹 네트워크에서 TCP 성능에 미치는 영향을 살펴본다.
