A key result of the Capital Asset Pricing Model (CAPM) is that the market portfolio— the portfolio of all assets in which each asset’s weight is proportional to its total market capitalization—lies on the mean-variance-efficient frontier, the set of portfolios having mean-variance characteristics that cannot be improved upon. Therefore, the CAPM cannot be consistent with efficient frontiers for...

The balanced Pytha...

Full integration of energy conversion devices for compact power supply circuits is still encountering strong technological locks, especially to integrate passive inductive and capacitive components. The increasing working frequency of those devices, which already reaches 1 Megahertz, would enable the size reduction of passive components and then their integration. Nevertheless, losses, which hi...

Most current work on spoken human-computer interaction has so far concentrated on interactions between a single user and a dialogue system. The advent of ideas of the computer or dialogue system as a conversational partner in a group of humans, for example within the CHIL-project and elsewhere (e.g. Kirchhoff & Ostendorf, 2003), introduces new requirements on the capabilities of the dialogue sy...
