We perform numerical simulations of several 3D uid-particle interaction problems. We simulate the sedimentation in a liquid lled tube of multiple spheres ranging in number from two to ve. The Navier-Stokes equations for incompressible ow are solved using the stabilized space-time nite element method. This method gives us the exibility to move the mesh to accommodate the motion of the spheres. A...

background: the present work aims to study the out-of-field photon calculation accuracy of a commercial treatment planning system (tps), oncentra, for three-dimensional conformal radiotherapy (3d-crt) and intensity modulated radiation therapy (imrt) treatment techniques from elekta synergy medical linear accelerator. materials and methods: accuracy of individual out-of-field dose components was...

Multiple views of a rigid 3D scene captured from a moving camera can be used to estimate the 3D poses (rotations and translations) and the 3D structure of the unmodeled scene. In this problem domain, there are two key problems addressed in this paper: (i) automatic Euclidean pose estimation in extended sequences even when views of the scene rapidly change, that is features come in and go out of...

This article describes an implementation of a basic multiprocessor system that exhibits replication and differentiation abilities on the POEtic tissue, a programmable hardware designed for bio-inspired applications [1, 2] . As for a living organism, whose existence starts with only one cell that first divides, our system begins with only one totipotent processor, able to implement any of the ce...
