| 1 | Kinematic Analysis and Experimental Verification on the Locomotion of Gecko显示文摘This paper presents a kinematic analysis of the locomotion of a gecko,and experimental verification of the kinematicmodel.Kinematic analysis is important for parameter design,dynamic analysis,and optimization in biomimetic robot research.The proposed kinematic analysis can simulate,without iteration,the locomotion of gecko satisfying the constraint conditionsthat maintain the position of the contacted feet on the surface.So the method has an advantage for analyzing the climbing motionof the quadruped mechanism in a real time application.The kinematic model of a gecko consists of four legs based on 7-degreesof freedom spherical-revolute-spherical joints and two revolute joints in the waist.The motion of the kinematic model issimulated based on measurement data of each joint.The motion of the kinematic model simulates the investigated real gecko’smotion by using the experimental results.The analysis solves the forward kinematics by considering the model as a combinationof closed and open serial mechanisms under the condition that maintains the contact positions of the attached feet on the ground.The motions of each joint are validated by comparing with the experimental results.In addition to the measured gait,three othergaits are simulated based on the kinematic model.The maximum strides of each gait are calculated by workspace analysis.Theresult can be used in biomimetic robot design and motion planning. | Woochul Nam TaeWon Seo Byungwook Kim DongsuJeon Kyu-Jin Cho Jongwon Kim | 2009 | Journal of Bionic Engineering2009，6，3： | 6 |

| 5 | Structural color switching with a doped indium-gallium-zinc-oxide semiconductor显示文摘Structural coloration techniques have improved display science due to their high durability in terms of resistance to bleaching and abrasion,and low energy consumption.Here,we propose and demonstrate an all-solid-state,large-area,lithography-free color filter that can switch structural color based on a doped semiconductor.Particularly,an indium-gallium-zinc-oxide(IGZO)thin film is used as a passive index-changing layer.The refractive index of the IGZO layer is tuned by controlling the charge carrier concentration;a hydrogen plasma treatment is used to control the conductivity of the IGZO layer.In this paper,we verify the color modulation using finite difference time domain simulations and experiments.The IGZO-based color filter technology proposed in this study will pave the way for charge-controlled tunable color filters displaying a wide gamut of colors on demand. | INKI KIM JUYOUNG YUN TREVON BADLOE HYUK PARK TAEWON SEO YOUNGHWAN YANG JUHOON KIM YOONYOUNG CHUNG AND JUNSUK RHO | 2020 | Photonics Research2020，8，9： | 3 |

| 15 | Numerical Study of the Effects of the Face Velocity onCeramic Filter显示文摘Time-averaged explicit Navier-Stokes equations with the modified Darcy’s law for the threedimensional cylindrical flow field were formulated to the problem. Numerical investigation of the effects of the face velocity on ceramic candle filter was executed in three-dimensional turbulent flow field. It is found that the flow in the vessel is pushed toward the filter region by the pressure difference between inside and outside of the filter due to the viscosity and inertial resistance. It is also found that the pressure drop is directly proportional to the flow rate and the slope of the pressure drop will be mitigated when the thickness of the filter cake (8) is larger than 10 mm. | Seo, Taewon(School of Mechanical Engineering, Andong National University, 388 Songchun-Dong, Andong,760-749, South Korea) | 1998 | Journal of Thermal Science1998，7，4： | 0 |
| 16 | INFLUENCE OF LARGE-SCALE VORTICAL STRUCTURES ON THE PARTICLE DISPERSION IN A PLANE MIXING LAYER显示文摘The present study considers the developing mixing layer that is formed by merging of two free streams initially separated by a splitter plate. To investigate the influence of the vortical structures on the particle dispersion, numerical simulation was conducted when the velocity ratio, defined as R=U_ ∞ -U_ -∞ U_ ∞ +U_ -∞ , is 0.5. Large-Eddy Simulation (LES) was employed to understand the effect of large-scale vortical structures originated by the Kelvin-Helmholtz instability on the partical dispersion. The flyash with the particle sizes 10, 50, 100, 150, and 200μm respectively were loaded at the origin of the two-dimensional mixing layer. It is confirmed that the particle dispersion depends strongly on the motion of large-scale vortical structures. The particle dispersion is visualized numerically by following the particle trajectories in the mixing layer undergoing pairing interaction. | Taewon Seo Yongkyoon Eom | 2002 | Journal of Hydrodynamics2002，14，4： | 0 |

| 18 | The Parametric Study on the Development of the Large-Scale Coherent Structures in a Mixing Layer显示文摘The theoretical investigation of the role of three-dimensional large-scale coherent structures and their mutual interactions in a developing plane mixing layer subjected to external forcing is presented. Large-scale coherent structures are decomposed into 3 fundamental and 2 subharmoic wave modes. A parametric study is carried out examining effects of a multitude of initial conditions. It is found that the evolution of the forced three-dimensional shear layer and the associated local entrainment can be influenced greatly by the initial amplitudes and phases of the large-scale modes. The presence of three-dimensional modes may have a profound effect on shear layer growth when forced at amplitudes comparable or larger than those of the two-dimensional ones. This effect is more pronounced at low frequency. Nonlinear interactions between the fundamentals and subharmonics indicate that subharmonics of the most amplified frequency of the shear layer are usually produced during the early stages of flow development, while its harmonics are always produced far downstream, regardless of initial conditions. The results of this study provide useful parametric information for the control, through multi-mode forcing, of shear layers in practical applications, aiming at mixing and transport augmentation. | Taewon Seo Yong-Kyoon Eom | 2002 | Journal of Thermal Science2002，11，1： | 0 |
