Aluminum alloys are considered a lot in the automotive and aerospace industry because of their high strength to weight ratio. In this manuscript, the gas forming process of aluminum AA6063 tubes at high temperatures up to 500°C is investigated, through experimental and numerical tests. Therefore, an experimental setup is prepared and so, tube specimens are formed in a die with square cross sect...

High Order Resolution and Parallel Implementation on Unstructured Grids. (December 1996) Yufeng Yao, University of Glasgow Supervisor: Professor B. E. Richards In this thesis the numerical solution of the two-dimensional compressible NavierStokes equations for the application on aerodynamic problems is tackled. The motivation is to develop a cell-centred upwind finite volume scheme with high or...

We examine connections between combinatorial notions that arise in machine learning and topological cubical/simplicial geometry. These enable to export results from geometry learning. Our first main result is based on a geometric construction by Tracy Hall (2004) [20] of partial shelling the cross-polytope which can not be extended. From it, we derive maximum class VC dimension 3 without corner...

[1] Mantle dynamics can strongly affect melting processes beneath spreading centers and volcanic arcs. A 2-D numerical model of the Tonga subduction zone, with the slab viscously coupled to the mantle beneath the brittleductile transition but faulted above, shows that induced corner flow may cause asymmetric melting at the Lau backarc spreading center, 400 km away. The down-going slab also entr...

Phonak led the way in modern frequency lowering technology with the introduction of SoundRecover in 2008. Since then, extensive worldwide field studies with adults and children have found increased detection, distinction and recognition of high frequency sounds, better speech understanding and significant improvement in intonation and overall voice quality for users. For those with more extreme...

An anisotropic refinement criterion suitable for Finite-Volume methods is presented and Navier–Stokes solutions are reported for the lid-driven cavity flow configuration at Re 1⁄4 1000 with adaptive anisotropic meshes (h-refinement). The a posteriori error estimation criterion is based on the assessment of the goodness-of-fit of the least squares regression used to perform the variables profile...
