Vom Außen aufs Innere schließen: Inverse Probleme in der Mathematik ermöglichen neue Einblicke

Inverse Probleme in der Mathematik bestimmen die Ursachen für Effekte: Beispielsweise kann man über das Messen von Spannungsverteilung an der Körperoberfläche auf die Beschaffenheit des Gewebes im Körper schließen. Die Lösung solcher Probleme ist derzeit häufig sehr rechenzeitintensiv. Barbara Kaltenbacher arbeitet daher nun in einem FWF-Projekt an neuen Rechenverfahren für allgemeine inverse Probleme.

More (open) facts for everyone: Publication of the new open access journal “Journal of Mechanism and Institution Design”

Research conducted at state universities is mostly financed with public money: As such, knowledge is a public good and should therefore also be publically accessible. Tradition dictates that research results are published in scientific journals, which are of vital importance for the career paths of researchers. However, even today, these journals are usually published by large publishing houses, whose respective business models prescribe the raising of revenues from public libraries and academic institutions. This is the case even though almost all of the articles that come to be published are penned by researchers who are largely publically funded. What is more, to a significant extent, the selection and peer review process applied to the articles is also conducted by researchers who receive publically funded salaries. In most instances, the performance of these duties – generally considered to be part of the scope of reputable academic activities – goes unpaid. Meanwhile, over the past few years, the trend towards “open access” has steadily gained pace: Conventional journal contributions are either “bought out” from authors’ contracts and published in a publically accessible manner (green road), or articles appear in journals established specifically for this purpose, which are committed to the provision of open access (gold road). The first batch of open access journals following the “gold road” is now beginning to emerge in the economic sciences, among them the recently initiated “Journal of Mechanism and Institution Design”.

Supermarket Home Delivery Efficiency Increased by 10 Per Cent

Delivery services by supermarket chains are on the fast track, with retail customers readily taking advantage of the option to have their everyday grocery needs delivered to their home within a defined time slot. For the chain stores, online retail activities involve a vast effort in terms of logistics, with much to lose, but also much to gain. A team of mathematicians at the Alpen-Adria-Universität, assembled by optimisation expert Philipp Hungerländer, has succeeded in increasing the efficiency of the delivery routes of a global retail brand in England by more than 10 per cent. As a result, the corporation has reduced its costs by several million Euros per year.
