While using more biometric traits in multimodal biometric fusion can effectively increase the system robustness, often, the cost associated to adding additional systems is not con...
We present an incentive-compatible polynomial-time approximation scheme for multiunit auctions with general k-minded player valuations. The mechanism fully optimizes over an appro...
Abstract. It is customary to write performance-critical parts of arithmetic functions in assembly: this enables finely-tuned algorithms that use specialized processor instructions....
Abstract. This paper gives an overview of XML formal models, summarizes database engineering practices, problems and their evolution. We focus on categorical aspects of XML formal ...
In the ForMoSA project [17] an integrated approach for safety analysis of critical, embedded systems has been developed. The approach brings together the best of engineering practi...
