Modelling the cryogenic environment aided by CFD & FEM to provide optimized solutions for unconventional manufacturing of aerospace alloys
منشور في 2020"…The optimization varies the cryogenic nozzle position in terms of separation distance from the tool-chip interface and the inclination angle from the vertical to determine the combination that leads to the minimum cutting forces. The study begins with a Computational Fluid Dynamics (CFD) model, aided by the results of Finite Element Modeling (FEM), to simulate the cryogenic environment for each of the nozzle positions and determine the optimal cooling effect. …"

On the parameterized complexity of dynamic problems
منشور في 2015"…In the parameterized version of such a problem, the changes made to an instance are bounded by an edit-parameter, while the cost of reconstructing a solution is bounded by some increment-parameter. Capitalizing on the recent initial work of Downey et al. on the Dynamic Dominating Set problem, we launch a study of the dynamic versions of a number of problems including Vertex Cover, Maximum Clique, Connected Vertex Cover and Connected Dominating Set. …"
