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 ...

Microstructure Evolution of 5052 Aluminum Sheet in Electromagnetic High-Speed Impact
Metals, 2020 Electromagnetic forming (EMF) is a high-speed forming technology, which can not only improve the formability of hard-to-form materials but also reduce springback.

Parity violating spin-two gauge theories
, 2003 Nonlinear covariant parity-violating deformations of free spin-two gauge theory are studied in n>2 spacetime dimensions, using a linearized frame and spin-connection formalism, for a set of massless spin-two fields.

A simple approach to interactive free-form shape deformations [PDF]
10th Pacific Conference on Computer Graphics and Applications, 2002. Proceedings., 2003 In this paper we propose a set of free-form shape deformation techniques. The basic approach can be described as follows. Given a surface represented by a mesh and a control point, for every mesh vertex let us consider the difference between the control point and the vertex. The vertex is shifted by a displacement equal to the difference, times a scale

On gauge-invariant deformation of reducible gauge theories
European Physical Journal C: Particles and Fields, 2022 New method for construction of gauge-invariant deformed theory from an initial gauge theory proposed in our previous papers (Buchbinder and Lavrov in JHEP 06:854, 2021; Buchbinder and Lavrov in Eur Phys J C 81:856, 2021) for closed/open gauge algebras is

Small- and Large-scale Characterization and Mixing Properties in a Thermally Driven Thin Liquid Film
, 2015 Thin liquid films are nanoscopic elements of foams, emulsions and suspensions, and form a paradigm for nanochannel transport that eventually test the limits of hydrodynamic descriptions.

Explicit B-spline regularization in diffeomorphic image registration
Frontiers in Neuroinformatics, 2013 Diffeomorphic mappings are central to image registration due largely to their topological properties and success in providing biologically plausible solutions to deformation and morphological estimation problems.
