Registration Using Sparse Free-Form Deformations [PDF]

, 2012
Non-rigid image registration using free-form deformations (FFD) is a widely used technique in medical image registration. The balance between robustness and accuracy is controlled by the control point grid spacing and the amount of regularization. In this paper, we revisit the classic FFD registration approach and propose a sparse representation for ...

Simulation analysis of deformation spring-back of free-form surface composite with cellular foam filling

Materials Research Express, 2021
Due to the complex thermo-chemical-mechanical coupling during the curing and forming process of composite materials, spring-back is commonly observed after forming, which makes the shape of parts after curing and forming deviate from the design shape ...

Angular quantization and form-factors in massive integrable models [PDF]

, 1997
We discuss an application of the method of the angular quantization to reconstruction of form-factors of local fields in massive integrable models. The general formalism is illustrated with examples of the Klein-Gordon, sinh-Gordon and Bullough-Dodd ...

Development of Free-Form Assembly-Type Mold Production Technology Using 3D Printing Technology

Buildings, 2023
Free-form molds are used for one-time curve configuration, and because they are produced through manpower, they have issues with reduced precision and the occurrence of errors.

A new sinusoidal shear deformation theory for bending, buckling, and vibration of functionally graded plates [PDF]

, 2012
A new sinusoidal shear deformation theory is developed for bending, buckling, and vibration of functionally graded plates. The theory accounts for sinusoidal distribution of transverse shear stress, and satisfies the free transverse shear stress ...

Growth and Deformation Simulation of Aluminum Bronze Grains Produced by Electron Beam Additive Manufacturing

Metals, 2022
When working out 3D building-up modes, it is necessary to predict the material properties of the resulting products. For this purpose, the crystallography of aluminum bronze grains after electron beam melting has been studied by EBSD analysis methods. To

An Effective Mesh Deformation Approach for Hull Shape Design by Optimization

Journal of Marine Science and Engineering, 2021
A method for the morphing of surface/volume meshes suitable to be used in hydrodynamic shape optimization is proposed. Built in the OpenFOAM environment, it relies on a Laplace equation that propagates the modifications of the surface boundaries ...

Wick type deformation quantization of Fedosov manifolds [PDF]

, 2001
A coordinate-free definition for Wick-type symbols is given for symplectic manifolds by means of the Fedosov procedure. The main ingredient of this approach is a bilinear symmetric form defined on the complexified tangent bundle of the symplectic ...

Free-form skeleton-driven mesh deformations

Proceedings of the eighth ACM symposium on Solid modeling and applications - SM '03, 2003
In this paper, we propose a new scheme for free-form skeleton-driven global mesh deformations. First a Voronoi-based skeletal mesh is extracted from a given original mesh. Next the skeletal mesh is modified by free-form deformations. Then a desired global shape deformation is obtained by reconstructing the shape corresponding to the deformed skeletal ...

Free-form solid modeling using deformations [PDF]

Computers & Graphics, 1990
Abstract One of the most important problems of available solid modeling systems is that the range of shapes generated is limited. It is not easy to model objects with free-form surfaces in a conventional solid modeling system. Such objects can be defined arbitrarily, but then operations on them are not transparent and complications occur.
