Researchers at the University of Calgary have developed a novel algorithm to more accurately determine the physical properties of oil reservoirs than widely employed methods such as linear and non-linear regression analysis. By employing a combination of fuzzy ranking and artificial neural networks, Dr. Wang’s group demonstrates that they can accurately model reservoir characteristics such as p...

Functionally Graded Scaffolds (FGSs) are porous biomaterials where porosity changes in space with a specific gradient. In spite of their wide use in bone tissue engineering, possible models that relate the scaffold gradient to the mechanical and biological requirements for the regeneration of the bony tissue are currently missing. In this study we attempt to bridge the gap by developing a mecha...

To prevent sympathetic detonation in a high performance magazine, barriers between stacks of munitions absorb donor fragments. Acceptor munitions may still initiate on impact of barrier debris or on being thrown into the walls of the magazine itself. These shocks can be reduced to a safe level by increasing the barrier's mass which reduces its velocity and the imparted shock. In addition a poro...

Pores and microfractures provide storage spaces migration pathways for gas accumulation in tight sandstones with low porosity permeability, acting as one of the controlling factors production. The development a rational rock physics model is essential better understanding elastic responses sandstone complex pore structures. Accordingly, seismic characterization pores based on provides valuable ...

1 ABSTRACT The continuous casting process is a widely used technique in modern steel plants. However, it is a complicated process that is not well understood. The objective of this research is to model the porosity and macrosegregation due to shrinkage related effects and solid deformation in the continuous casting of steel. Solid phase movements due to bulging and variable roll gap are modeled...

The use of sonic log data to analyse overpressure in the Cooper Basin, South Australia is complicated by the occurrence of Tertiary uplift in the basin. Uplift and overpressure are both associated with anomalous porosity/depth relationships: the former being witnessed by overcompaction and the later by undercompaction. Hence uplift may mask overpressure effects on log data. A normal compaction ...
