Fluid dynamics and mechanical stress of tissue heart valves. Major problems with thrombo-embolic complications and leaflet failure and calcification still exist with bioprosthetic valves. Valves fabricated from polyether urethanes are efficient and can offer more resistance to calcification. No complete study on the haemodynamics and structure interactions is found in literature. Moreover, todate the effect of aortic wall motion on the blood flow has never been examined. A complete holistic ap ....Fluid dynamics and mechanical stress of tissue heart valves. Major problems with thrombo-embolic complications and leaflet failure and calcification still exist with bioprosthetic valves. Valves fabricated from polyether urethanes are efficient and can offer more resistance to calcification. No complete study on the haemodynamics and structure interactions is found in literature. Moreover, todate the effect of aortic wall motion on the blood flow has never been examined. A complete holistic approach to simulataneuosly simulating the fluid dynamics, the valve motion and the stress in a synthetic Polyether urethane valve is proposed. Cell adhesion study will also be carried out. The findings may yield to new insights into valve research.Read moreRead less
Digital Imagery for Building 3D City Models. The project will investigate the application of digital photogrammetric imagery, and primarily high-resolution satellite imagery for the creation of visually realistic 3D city models. Virtual reality computer models of urban scenes find application in urban planning, facilities management, engineering and even virtual tourism. Building upon recently initiated collaborative research, the project aims to develop improved methods and procedures for autom ....Digital Imagery for Building 3D City Models. The project will investigate the application of digital photogrammetric imagery, and primarily high-resolution satellite imagery for the creation of visually realistic 3D city models. Virtual reality computer models of urban scenes find application in urban planning, facilities management, engineering and even virtual tourism. Building upon recently initiated collaborative research, the project aims to develop improved methods and procedures for automated, image-based object reconstruction to support the generation of metrically accurate 3D computer models of buildings and the built environment.Read moreRead less
