An efficient algorithm determines the blank shape necessary to manufacture a surface by press forming. The technique is independent of material properties and instead uses surface geometry and an area conservation constraint to generate a geometrically feasible blank shape. The algorithm is formulated as an approximate geometric interpretation of the reversal of the forming process. The primary...

In this paper, the optimum shape of Tailor-Welded Blanks (TWB) is investigated. The optimization is performed for two different case studies. The first example is deep drawing of a TWB with dissimilar materials and uniform thicknesses and the next example is deep drawing of a TWB with similar materials and non-uniform thicknesses. The effect of blank optimization on the weld line movement is...

In an effort to reduce the experimental bias involved in the analysis of gaseous elemental mercury (Hg(o)), the blank response from gold-coated adsorption tubes has been investigated using cold vapor atomic absorption spectrometry (CVAAS). Our study has been compared with our recent investigation on memory effect in a cold vapour atomic fluorescence spectrometry (CVAFS). The pattern of blank re...

This paper maps out the design space of urban locationrelated mood self-tracking as starting point for individual and urban reflection: What are the benefits for key stakeholders, and what are system design options? Data-driven reflection here means that reflection is based on data; in this instance taking mood related to public spaces as starting point for reflection, but “attaching” to mood a...

Im Rahmen der Umsetzung der europäischen Wasserrahmenrichtlinie sind die Auswirkungen menschlicher Tätigkeit auf die Wasserkörper zu ermitteln. Für den Bereich der Landwirtschaft kann dies mit Hilfe von Nährstoffbilanzen erfolgen. Modelle nach dem top-down-Ansatz hatten in der Vergangenheit häufig das Problem, auf Grund stark aggregierter Eingangsdaten ungenaue Ergebnisse zu liefern. Durch die ...
