Apart from non-shape information, such as age, material, etc., the model also consists of shape information and shape feature information. Shape information is collected by Lasers Scanner and geometric modelling techniques. Feature information is generated from shape information via feature extracting techniques. The model is used in an integrated storage, archival, and sketch-based query and retrieval system for 3D objects, native American ceramic vessels. A novel aspect of the information model is that it is totally implemented with XML, and is designed for Web-based visual query and storage application.展开更多

An on--demand beam pulsing system is useful for the PIXE analysis of delicate objectS. IXX (or PIXE--induced XRF) is more suitable than PIXE in terms of damage to the sample. Some new PIXE and IXX applications of archaeological paper--like samples in recent years are given.展开更多
