Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：An active contour model with local variance force term and its efficient minimization solver for multi-phase image
局部方差力项 活动轮廓模型 多相图像 最小化求解器
2023/5/8
In this work, we propose an active contour model with a local variance force (LVF) term that can be applied to multi-phase image segmentation problems. With the LVF, the proposed model is very effecti...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Dynamics near a shear flow with Coriolis force
科里奥利力 剪切流 动力学
2023/5/16
In this talk, I will discuss the dynamics near a shear flow when the Coriolis force is involved. Compared with the non-Coriolis case, the spectral properties of the linearized Euler operator change fu...
Tool use has long been a hallmark of human intelligence, as well as a practical problem to solve for a vast array of robotic applications. But machines are still wonky at exerting just the right amoun...

DEM simulation of impact force exerted by granular flow on rigid structures
Avalanche DEM Granular flow Impact force
2015/7/1
The paper presents a DEM model for simulating dry granular avalanche down an incline. Flow pattern and impact forces on rigid obstacles are considered. Results of the simulations are compared with exp...
Estimating the impact force generated by granular flow on a rigid obstruction
Debris flow Fluid dynamics Granular flow Impact force Slope failure
2015/7/1
Flowing sediments such as debris and liquefied soils could exert a tremendous amount of force as they impact objects along their paths. The total impact force generally varies with slope angle, veloci...
