Numerical study on the effect of reservoir heterogeneity and gas supply on hydrate accumulation in subsea shallow formations

Seepage-type gas hydrate accumulation in subsea shallow formations involves complicated thermo-hydro-solid coupling processes and matching problem between various accumulation elements.The formation physical properties control local natural gas migration pathway and thus the final reservoir characteristics of hydrates.In this paper, a novel mixed-f

2D Hand Tracking Based on Flocking with Obstacle Avoidance

Hand gesture-based interaction provides a natural and powerful means for human-computer interaction.It is also a good interface for human-robot interaction.However, most of the existing proposals are likely to fail when they meet some ugg ultra mini grade school skin-coloured objects, especially the face region.In this paper, we present a novel han
