Modeling of multifunctional deformable porous scaffolds for soft tissue engineering [PDF]

, 2012
Porous membranes/scaffolds such as guided tissue regeneration (GTR) membranes, cell sheets, tissue matrices or polymeric meshes are being widely used in soft tissue engineering to regenerate damaged, diseased tissue or wound.

The outliers of a deformed Wigner matrix

, 2014
We derive the joint asymptotic distribution of the outlier eigenvalues of an additively deformed Wigner matrix $H$. Our only assumptions on the deformation are that its rank be fixed and its norm bounded.

Locality-Preserving Free-Form Deformation

The Visual Computer
Abstract This paper proposes a method to estimate the locations of grid handles in free-form deformation (FFD) while preserving the local shape characteristics of the 2D/3D input model embedded into the grid, named locality-preserving FFD (lp-FFD). Users first specify some vertex locations in the input model and grid handle locations.

Adaptive Free-Form Deformation Parameterization Based on Spring Analogy Method for Aerodynamic Shape Optimization

Fluids
An adaptive Free-Form Deformation parameterization method based on a spring analogy is presented for aerodynamic shape optimization problems. The proposed method effectively incorporates the gradients of the objective and constraint functions, achieving ...

DeformNet: Free-Form Deformation Network for 3D Shape Reconstruction from a Single Image

, 2017
3D reconstruction from a single image is a key problem in multiple applications ranging from robotic manipulation to augmented reality. Prior methods have tackled this problem through generative models which predict 3D reconstructions as voxels or point ...

Computational Design Optimization for S-Ducts

Designs, 2018
In this work, we investigate the computational design of a typical S-Duct that is found in the literature. We model the design problem as a shape optimization study. The design parameters describe the 3D geometrical changes to the shape of the S-Duct and
