Microstructure Identification of Additive Manufactured Titanium Alloy by Using Lamb Wave-DenseNet Network. [PDF]
Sensors (Basel)In the additive manufacturing (AM) process, dynamic fluctuations in process parameters often result in non-uniform grain sizes in the microstructures of fabricated components, which impairs their stability of mechanical performance.

A Hierarchical Approach for Regular Centroidal Voronoi Tessellations [PDF]
Computer Graphics Forum, 2016 International audienceIn this paper we consider Centroidal Voronoi Tessellations (CVTs) and study their regularity. CVTs are geometric structures that enable regular tessellations of geometric objects and are widely used in shape modeling and analysis ...

Centroidal Voronoi Tessellations: Applications and Algorithms [PDF]
SIAM Review, 1999 A centroidal Voronoi tessellation is a Voronoi tessellation whose generating points are the centroids (centers of mass) of the corresponding Voronoi regions. This paper gives some applications of centroidal tessellation to problems in image compression, quadrature, finite difference methods and statistics, etc. The authors discuss methods for computing

GPU-Assisted Computation of Centroidal Voronoi Tessellation [PDF]
IEEE Transactions on Visualization and Computer Graphics, 2011 Centroidal Voronoi tessellations (CVT) are widely used in computational science and engineering. The most commonly used method is Lloyd's method, and recently the L-BFGS method is shown to be faster than Lloyd's method for computing the CVT. However, these methods run on the CPU and are still too slow for many practical applications.
