In this paper a novel approach is described for tree visualization using nested circles. The brother nodes at the same level are represented by externally tangent circles; the tree nodes at different levels are displayed by using 2D nested circles or 3D nested cylinders. A new layout algorithm for tree structure is described. It provides a good overview for(More)
Monte Carlo (MC) methods are the gold standard for modeling photon and electron transport in a heterogeneous medium; however, their computational cost prohibits their routine use in the clinic. Cloud computing, wherein computing resources are allocated on-demand from a third party, is a new approach for high performance computing and is implemented to(More)
OBJECTIVES As adults with cerebral palsy (CP) are surviving longer, interventions are needed to reduce spasticity and increase strength to improve mobility and life quality. Adults with CP are lacking a form of independent exercise that allows them to maintain or improve their ambulation skills. A new approach to increase muscle strength and flexibility(More)
