The Eccentricity Transform (of a Digital Shape) [PDF]

open access: yes, 2006
Eccentricity measures the shortest length of the paths from a given vertex v to reach any other vertex w of a connected graph Computed for every vertex v it transforms the connectivity structure of the graph into a set of values For a connected region of a digital image it is defined through its neighbourhood graph and the given metric This transform ...

Theoretical modelling of the effect of plasticity on reverse transformation in superelastic shape memory alloys [PDF]

open access: yes, 2003
Stimulated by recent experimental results on superelastic NiTi shape memory alloy, a theoretical study is carried out to quantify the effect of plasticity on stress-induced martensite transformation, using a constitutive model that combines phase ...

SHAPE-ID Toolkit Resources - Develop a Career in Inter- or Transdisciplinary Research

open access: yes, 2021
Early-stage researchers, in particular, can receive very mixed messages about the wisdom of pursuing an inter- or transdisciplinary research career which is often regarded as high risk within a research system that is still primarily structured on ...

Shape Morphing Using PDE Surfaces [PDF]

open access: yes, 2006
YesA methodology for shape morphing using partial differential equation (PDE) surfaces is presented in this work. The use of the PDE formulation shows how shape morphing can be based on a boundary-value approach by which intermediate shapes can be ...

Thermal cycling stability of Ni55Mn25Ga18Ti2 high-temperature shape memory alloy

open access: yes工程科学学报, 2022
Research on high-temperature shape memory alloys has attracted much attention due to the control requirements of the high-temperature drive (>100 ℃) and the overheating warning in high voltage transmissions, nuclear power, aerospace, automotive, oil ...

Thermally driven phase transformation in shape-memory alloys [PDF]

open access: yes, 2007
This paper analyzes a model for phase transformation in shape-memory alloys induced by temperature changes and by mechanical loading. We assume that the temperature is prescribed and formulate the problem within the framework of the energetic theory of ...

Transformation Volume Effects on Shape Memory Alloys

open access: yesMetals, 2013
It is generally accepted that the martensitic transformations (MTs) in the shape memory alloys (SMAs) are mainly characterized by the shear deformation of the crystal lattice that arises in the course of MT, while a comparatively small volume change ...

On a Shape Adaptive Image Ray Transform [PDF]

open access: yes2013 International Conference on Signal-Image Technology & Internet-Based Systems, 2013
A conventional approach to image analysis is to perform separately feature extraction at a low level (such as edge detection) and follow this with high level feature extraction to determine structure (e.g. by collecting edge points using the Hough transform.

Shape Memory Properties and Microstructure of New Iron-Based FeNiCoAlTiNb Shape Memory Alloys

open access: yesCrystals, 2021
The shape memory properties and microstructure of Fe41Ni28Co17Al11.5(Ti+Nb)2.5 (at.%) cold-rolled alloys were studied at the first time using the values reported in constant stress thermal cycling experiments in a three-point bending test.

On shape transformations and shape fluctuations of cellular compartments and vesicles [PDF]

open access: yesPhysica Scripta, 1993
We discuss the shape formation and shape transitions of simple bilayer vesicles in context with their role in biology. In the first part several classes of shape changes of vesicles of one lipid component are described and it is shown that these can be explained in terms of the bending energy concept in particular augmented by the bilayer coupling ...
