Aluminum and magnesium alloys are of materials for decreasing vehicle weight and consequently reducing fuel consumption. However, forming limitations regarding their low formability at room temperature are found when being manufactured by conventional forming processes. For this reason, development of new forming techniques, such as warm tube hydroforming, is needed to overcome such limitations...

The purpose of this paper is to investigate how trans-aural processing can enhance conventional multichannel audio both by embedding perceptually relevant information and by improving image stability using additional loudspeakers integrated with supplementary digital processing and coding. The key objective is to achieve scala-bility in spatial performance while retaining full compatibility wit...
