In kinematic synthesis and analysis of planar mechanisms the designer must define a geometry and set of motions for a design task. This paper will focus on how to determine the forces or torques acting on the planar mechanism by numerical method when acceleration and dynamic properties of the linkage are known.

Calculating intra-aneurysm flow uses optical flow with computational fluid dynamics simulation on the numerical analysis. This is a new method to better understand the intravascular flow and aneurysm flow as well as factors related to the inflow vortex and the inflow jet which increase the rupture risk in patients with an aneurysm.
