A new approach is proposed for finding the ”best cut” in a hierarchy of partitions by energy minimization. Said energy must be ”climbing” i.e. it must be hierarchically and scale increasing. It encompasses separable energies and those composed under supremum.

This paper is concerned with a novel, fully variational formulation for finite deformation analysis of inelastic membranes with wrinkling. In contrast to conventional approaches, every aspect of the physical problem derives from minimization of suitable energy functionals. A variational formulation of finite strain plasticity theory, which leads to a minimization problem for the constitutive up...

The prolate-to-oblate shape transition of phospholipid vesicles in response to frequency variation of an AC electric field can be explained by the dielectric anisotropy of a phospholipid bilayer Abstract. The external electric field deforms flaccid phospholipid vesicles into spheroidal bodies, with the rotational axis aligned with its direction. Deformation is frequency dependent: in the low fr...

One of the greatest shortcomings of macromolecular energy minimization and molecular dynamics techniques is that they generally do not preserve the native structure of proteins as observed by x-ray crystallography. This deformation of the native structure means that these methods are not generally used to refine structures produced by homology-modeling techniques. Here, we use a database of 75 ...

This thesis focuses on deformation tracking and diffeomorphic matching in 2D or 3D medical imaging. We have developed and implemented novel algorithmic approaches to track both the myocardial motion in 2D IntraCardiac Echocardiography images and the Mitral Valve deformation in 3D ultrasound images. We studied the myocardial deformation through the registration of IntraCardiac Echocardiography i...

in this study, the effect of tensile test temperature (148 to 673 k) on the microstructural evolutions and the mechanicalproperties of high manganese twinning induced plasticity (twip) steel with the chemical composition of fe-31mn-3al-3si (wt. %) was investigated. xrd, sem and tem were used to study the microstructural evolutions.stacking fault energy (sfe) of the alloy was also calculated by ...

In this paper, an upper bound approach is used to analyze the tube extrusion process through rotating conical dies with large mandrel radius. The material under deformation in the die and inside the container is divided to four deformation zones. A velocity field for each deformation zone is developed to evaluate the internal powers and the powers dissipated on all frictional and velocity disco...
