Research on virtual osteotomy in cranio-maxillofacial surgical planning;

The method employs an energy function to extract a dummy skeleton of a human body from the silhouette,and then estimates the position of the joints by the knowledge of anthropotomy.

An approximation algorithm of virtual backbone formation (VBF) based on a more generalized and realistic wireless network communication model of bounded growth graph (GBG) was proposed.

To solve the problem of performance worsening on scheduling key transactions induced by intensive data accessing in large scale e-trading, the paper classifies the varieties of trading transactions and investigates on their unique structures, and presents a two-stage schedule policy based on virtual deadline and timestamp ordering.
