PARAMETERIZATION USING MANIFOLDS

CINDY M. GRIMM
2004 International journal of shape modeling  
Possible applications include texture mapping, surface fitting, arbitrary topology surface modeling, feature detection, and surface comparison.  ...  There are a variety of surface types (such as meshes and implicit surfaces) that lack a natural parameterization.  ...  These metrics can then be used for applications such as feature extraction, shape classification, and comparisons of 3D objects.  ...

An integrated methodology for assessing physical and technological life of products for reuse

Fatida Rugrungruang, Sami Kara, Hartmut Kaebernick
2009 International Journal of Sustainable Manufacturing (IJSM)  
However, the implementation of reuse strategies has been hindered by the requirement of reliable methodologies to assess the remaining life and reuse potential of used components.  ...  The estimation of the remaining life is problematic as the useful life of a component is affected by several causes of obsolescence. The common causes are due to physical and technological issues.  ...  Mathematical modelling of an S-shaped curve Chapter 2 has already discussed a number of S-curve mathematical models.  ...
