Microarrays enable to measure the expression levels of tens of thousands of genes simultaneously. One important statistical question in such experiments is which of the several thousand genes are differentially expressed. Answering this question requires methods that can deal with multiple...

Online offerings such as web search, news portals, and e-commerce applications face the challenge of providing high-quality service to a large, heterogeneous user base. Recent efforts have highlighted the potential to improve performance by introducing methods to personalize services based on...

This thesis investigates the specific characteristics of products from renewable resources and analyses how they affect the choice of efficient coordination mechanisms in business-to-business relationships. Due to the diversity and heterogeneity of renewable resources, this is done by means of...

We analyze the impact minimal capital and reserve requirements have on bank failures arising from solvency and liquidity shortages in a banking system where banks are characterized by the amount of capital, cash reserves and their exposure to the interbank loan market as borrowers as well as...

We model a stylized banking system where banks are characterized by the amount of capital, cash reserves and their exposure to the interbank loan market as borrowers as well as lenders. A network of interbank lending is established that is used as a transmission mechanism for the failure of...
