"Inverse Problems in Industry: Modelling and Computation"
In this talk, we will present the recent works based on the correlation between our group and industry. The modelling and computation of the forward problems and inverse problems are stressed. By several interesting examples, we show that, the theoretic analysis of mathematical model and techniques of inverse problems are so important for giving the effective solutions for the real problems.

"Visual Simulation of Natural Phenomena based on Computational Fluid Dynamics"
Visual simulation of natural phenomena has become one of the most important research topics in computer graphics. Such phenomena include water, fire, smoke, clouds, and so on. Realistic simulation of these phenomena can be achieved by solving a set of partial differential equations, called Navier-Stokes equations. In this talk, I will briefly review the Navier-Stokes equations and explain how the equations can be applied to the simulation of various natural phenomena. I will also explain some methods to control the simulation in order to produce desired visual effects.

"Algebraic and Topological Approaches to Visualizing Complexities"
Extracting meaningful features in spatiotemporal behaviors of datasets has been a key issue in computer graphics and visualization, due to its ability to analyze and understand the underlying complexities. This talk provides two different approaches to this issue, an algebraic approach for characterizing the relationships among data samples and a topological approach for delineating data distribution into a skeleton-like structure. We applied these approaches to a variety of problems including watermarking 3D models, simulating group formations, enhancing volume visualization, and skeletonization of high-dimensional datasets.
