Coarctation of the aorta (CoA) is one of the most common congenital cardiac anomalies that could be corrected by surgery. However, the effects of surgical anastomosis on aortic arch flow are still unknown. In this study, a unique three-dimensional way was utilized to measure the growth of anastomotic site and computational fluid dynamics (CFD) was applied to investigate the hemodynamic effects of...
Pulmonary artery banding (PAB) is a commonly used palliative procedure to restrict excess pulmonary blood in certain congenital heart diseases. However, many associated long-term hemodynamic problems still remain unsolved over the years. In this study, we utilized the method of computational fluid dynamics (CFD) to investigate the hemodynamic effects of PAB on patient-specific pulmonary flow before,...
Above 70 percent of production cost is determined by development and test phase. Modern simulation method can be used to simulate test process and substitute prototype manufacturing and test phase when finishing design proposal. Test simulation can effectively find design flaws and provide engineer direct reference to modify original design or remodel. Based on practical example of mobile phone, preparation...
The paper presents the design of the arm of performance enhanced humanoid BHR-03, which is characterized by its light weight construction, a modular, multi-sensory joint design with brushless motors and an electronics architecture using decentralized joint controllers. In the previous humanoid robots we mainly focus on the biped walking control, motion plan and high stiffness design of the limb. In...
