Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：The level-set percolation of Gaussian free field
高斯自由场 水平 集渗流
2023/5/17
In this lecture, I will discuss some of the recent progresses in the level-set percolation of Gaussian free field in (d\geq 3), including the positivity of threshold and (if time permits) sharp phase ...

A Hybrid Variational Front Tracking-Level Set Mesh Generator For Problems Exhibiting Large Deformations and Topological Changes
Front Tracking Arbitrary-Lagrangian-Eulerian Mesh Method
2015/12/11
We present a method for generating 2-D unstructured triangular meshes that undergo large deformations and
topological changes in an automatic way. We employ a method for detecting when topological ch...
Polynomial level-set methods for nonlinear dynamical systems analysis
dynamical systems analysis level-set methods
2015/6/19
In this paper, we present a method for computing the domain of attraction for non-linear dynamical systems. We propose a level-set method where sets are represented as sublevel sets of polynomials. Th...
Using the level set method in geodynamical modeling of multi-material flows and Earth's free surface
Tracking the material surface flow modeling multi - material flow modeling the level set function
2015/1/6
The level set method allows for tracking material surfaces in 2-D and 3-D flow modeling and is well suited for applications of multi-material flow modeling. The level set method utilizes smooth level ...
Level set estimation from projection measurements: Performance guarantees and fast computation
estimation projection measurements Performance guarantees fast computation
2012/11/22
Estimation of the level set of a function (i.e., regions where the function exceeds some value) is an important problem with applications in digital elevation mapping, medical imaging, astronomy, etc....
A Multi-mesh Adaptive Level Set Approach for Incompressible Two-Phase Flow
level set method multi-mesh adaptive finite element method reinitializa- tion
2015/5/6
In this paper, we propose a multi-mesh h-adaptive method to solve the level set model of incompressible two-phase flow. In the method, we approximate the flow variables and the level set function on t...
Incorporating level set methods in Geographical Information Systems (GIS) for land-surface process modeling
level set methods Geographical Information Systems (GIS) land-surface process modeling
2010/1/25
Land-surface processes include a broad class of models that operate at a landscape scale. Current modelling approaches tend to be specialised towards one type of process, yet it is the interaction of ...
