DOI: 10.1002/cnm.3580
Abstract: A physics‐based medical image segmentation method is developed. Specifically, the image greyscale intensity is used to infer the voxel partial volumes and subsequently formulate a porous medium analogy. The method involves first translating the medical… read more here.

DOI: 10.1007/s11440-019-00762-5
Abstract: Significant chemical influence on the swelling potential of MX-80 bentonite was observed during swelling tests where specimens were hydrated with highly concentrated brine. The maximum swelling pressure for specimens hydrated with brine was about 30%… read more here.

DOI: 10.1007/s11663-019-01642-9
Abstract: A FLUENT™-based thermal-fluid-compositional model has been developed and applied to a low-pressure, die-cast, A356 aluminum alloy wheel to explore the effects of macro-segregation of hydrogen and late-stage liquid encapsulation on pore formation during solidification. Based… read more here.

DOI: 10.1016/j.jappgeo.2018.09.032
Abstract: Abstract The electrical resistivity of fractured rocks as a double-porosity system including matrix pore and fracture has been investigated by porosity models based on the parallel-circuit configurations of pore space. These existing porosity models only… read more here.
