Compounding local invariant features and global deformable geometry for medical image registration.
PLoS ONE, 2014 Using deformable models to register medical images can result in problems of initialization of deformable models and robustness and accuracy of matching of inter-subject anatomical variability.

Deformations of bundles and the Standard Model [PDF]
Physics Letters B, 2007 We modify a recently proposed heterotic model hep-th/0703210, giving three net-generations of standard model fermions, to get rid of an additional U(1) factor in the gauge group. The method employs a stable SU(5) bundle on a Calabi-Yau threefold admitting a free involution. The bundle has to be built as a deformation of the direct sum of a stable SU(4)

Activity Representation Using 3D Shape Models
EURASIP Journal on Image and Video Processing, 2008 We present a method for characterizing human activities using 3D deformable shape models. The motion trajectories of points extracted from objects involved in the activity are used to build models for each activity, and these models are used for ...

On the study of some geological structure models [PDF]
E3S Web of Conferences, 2023 In this work, we study problems of harmonic vibrations of extended elastic structures with a coating. The studied boundary value problems can have different physical interpretations; in this case, they are considered as models of geological structures ...

Real-Time Surface-Based Volume Constraints on Mass-Spring Model in Unity3D
IEEE Access, 2023 This paper describes a parallel method to simulate real-time 3D deformable objects using volume preservation constraints on a mass-spring model (MSM) to achieve plausible results in real-time performance. Instead of considering a volumetric mesh which is

Fabrication of deformable patient-specific AAA models by material casting techniques
Frontiers in Cardiovascular Medicine, 2023 BackgroundAbdominal Aortic Aneurysm (AAA) is a balloon-like dilatation that can be life-threatening if not treated. Fabricating patient-specific AAA models can be beneficial for in-vitro investigations of hemodynamics, as well as for pre-surgical ...
