  • 이 논문에서는 충격성 잡음환경에서 탁월한 성능을 보이는 CIPD 알고리즘에 대해, 오차에 대한 가우시안 커널로 입력이 보정된 MCI의 전력 추이를 가중치 갱신 방정식에 반영한 새로운 방식을 제안하였다. 제안한 알고리즘이 기존의 CIPD 알고리즘보다 우수한 성능을 가지는지 평가하기 위해, 각 알고리즘의 가중치 벡터 변화량이 얼마나 충격성 잡음에 강인한가를 충격성 잡음하에서 비교하였으며, 실험 결과에서 2배 이상의 정상상태 안정성 향상, 약 1.8배 빠른 수렴속도와 약 2dB 정도 더 낮은 최소 MSE 값을 나타냈다.

  • It has been known that the inertial dynamics has a little effect on the reaction rate in solutions. In this work, however, we find that for diffusion-controlled reactions between a ligand and a receptor on the cell surface there is a noticeable inertial dynamic effect on the reaction rate. We estimate the magnitude of the inertial dynamic effect by comparing the approximate analytic results obtained with and without the inertial dynamic effect included. The magnitude of the inertial dynamic effect depends on the friction coefficient of the ligand as well as on the relative scale of the receptor size to the distance traveled by the ligand during its velocity relaxation time.

  • This paper presents the reduction characteristics of penetrated electromagnetic fields through a narrow slot in a planar conducting screen of infinite extent. When a plane wave is excited to the narrow slot, the aperture electric field is controlled by the parallel wire or parallel plate connected on the slot. The magnitude of penetrated electromagnetic fields through a narrow slot is controlled by electric field distributions on the slot. An integral equation for the aperture electric field on narrow slots is derived and solved by applying Galerkin's method of moments. The results show that the magnitude of the penetrated electromagnetic field can be effectively reduced by installing the parallel wire or parallel plate on the slot.

  • In this paper, a novel structure Bearingless SRM with hybrid stator poles is proposed. The motor torque can be controlled independently from radial force control. Analytical models of torque and radial force for proposed structure are explained. Based on these models, control scheme of desired radial force is proposed. In this control method, the magnitude of force can be controlled in arbitrary direction and magnitude by selecting some combinations of radial force windings. The validities of structure and control method are verified by the experimental results when motor is at standstill and running.

  • This paper derives a condition foe constant voltage i constant frequency generation of doubly-fed induction generator. The condition is varied by the magnitude of output voltage, load current and its power factor, slip of the machine. Magnitude of output voltage is controlled by exiting voltage which is caculated by derived equation from operating condition. frequency of output voltage is controlled by injecting slip frequency to the rotor which is the difference between wanted output frequency and rotor frequency.

  • 신호처리에서 영확률을 성능기준으로 하는 적응 알고리듬들은 충격성 잡음 환경에서 우수한 성능과 안정된 수렴을 보인다. 이 논문에서는 MSE 성능기준과 비교분석을 통해 영확률 성능기준이 MSE와 동일한 최적해를 가진다는 것을 증명한다. 또한 이 연구를 통해, 영확률 기반 알고리듬의 크기 조정된 입력이 충격성 잡음으로부터 최적해가 방해 받지 않도록 유지해주는 역할을 하고 있음을 보인다.
