Multi-objective optimization of nitinol stent design.
Nitinol stents continuously experience loadings due to pulsatile pressure, thus a given stent design should possess an adequate fatigue strength and, at the same time, it should guarantee a sufficient vessel scaffolding. The present study proposes an optimization framework aiming at increasing the fatigue life reducing the maximum strut strain along the structure through a local modification of the strut profile.The adopted computational framework relies on nonlinear structural finite element analysis combined with a Multi Objective Genetic Algorithm, based on Kriging response surfaces. In particular, such an approach is used to investigate the design optimization of planar stent cell.The r…
DOPA Explorer 2.0: A web based tool assessing all large protected areas in support to conservation policies
The Digital Observatory for Protected Areas (DOPA) has been developed to support the European Union's efforts in strengthening our capacity to mobilize and use biodiversity data, information and forecasts so that they are readily accessible to policymakers, managers, experts and other users. Conceived as a set of web based services [1,2], DOPA provides a broad set of free and open source tools to assess, monitor and even forecast the state of and pressure on protected areas at local, regional and global scale. Recognized by the UN Convention on Biological Diversity (CBD) as a reference information system, DOPA Explorer is a web based interface of the DOPA providing simple means to rank prot…
