With increasing development of Internet, grid as a new structure of distributed network will be discussed more and more, while its security is facing the heavy challenge and restricts application of grid. The international research shows that grid security is on the way to trustworthy grid. Apart from current trust model, the future trust model in grid should add users' behaviors reflecting users'...
Realistic surgical simulation should take into account the mechanical properties of soft tissue, and also patient-specific variations. Consequently automated methods are required for the acquisition and modeling of patient-specific tissue properties.We take a step toward this goal by presenting a semiautomated method for acquiring, modeling, and simulating soft-tissue deformation. During a typical...
Focusing on the fact that the collection of independent tasks to be scheduled onto the grid is always on a large-scale, a conception of task partition is proposed to group tasks exclusively according to the machine that gives the earliest completion time. As a result, several tasks in different task partitions can be scheduled at the same time, which reduces the range of task searching and eliminates...
