Analysis of Rock Microstructure Using High- Resolution X-ray Tomography
In previous work we have described and validated robust techniques for partitioning the pore space of a porous material into simple regions, thereby allowing it to be represented by a network of simple building blocks. The primary purpose of this analysis is the generation of a pore-throat network for modelling immiscible multi-phase fluid displacements. However, combining our partitioning algo...
متن کاملDifferential interference contrast x-ray microscopy with submicron resolution
Progress in lithography and nanofabrication @E. Di Fabrizio et al., Nature ~London! 401, 895 ~1999!# has made it possible to apply differential interference contrast ~DIC! in x-ray microscopy using an original x-ray doublet lens based on two specially developed zone plates. Switching from bright-field imaging ~absorption contrast! to x-ray DIC, we observe, similar to visible-light microscopy, a...
متن کاملAnalysis of the Microstructure and Deformation of Woven Composites Using Microfocus X-ray Diffraction
Unidirectional (UD) prepreg based laminates, consolidated in an autoclave, have been the principal material choice for the composites industry especially for aerospace application. There are concerns, however, about the damage tolerance and compression after impact (CAI) performance of UD composites, in addition to the high manufacturing and material costs. In recent years, the composites indus...
متن کاملModeling and Measurement of 3D Deformation of Scoliotic Spine Using 2D X-ray Images
Scoliosis causes deformations such as twisting and lateral bending of the spine. To correct scoliotic deformation, the extents of 3D spinal deformation need to be measured. This paper studies the modeling and measurement of scoliotic spine based on 3D curve model. Through modeling the spine as a 3D Cosserat rod, the 3D structure of a scoliotic spine can be recovered by obtaining the minimum pot...
متن کاملPrecision measurement of the 3 d → 2 p x - ray energy in kaonic 4 He
We have measured the Balmer-series x-rays of kaonic 4He atoms using novel largearea silicon drift x-ray detectors in order to study the low-energy K̄-nucleus strong interaction. The energy of the 3d → 2p transition was determined to be 6467 ± 3 (stat) ±2 (syst) eV. The resulting strong-interaction energy-level shift is in agreement with theoretical calculations, thus eliminating a long-standing ...
