The virtualization and softwarization of modern computer networks offers new opportunities for the simplified management and flexible placement of middleboxes as e.g. firewall...
Control planes of forthcoming Software-Defined Networks (SDNs) will be distributed: to ensure availability and faulttolerance, to improve load-balancing, and to reduce overheads,...
To ensure the stability of the power grid, backup capacities are called upon when electricity supply does not meet demand due to unexpected changes in the grid. As part of the dem...

We formulate the capacity expansion planning as a bilevel optimization to model the hierarchical decision structure involving industrial producers and consumers. The formulation i...

Increased volatility in electricity prices and new emerging demand side management opportunities call for efficient tools for the optimal operation of powerintensive processes. In...

The multiperiod blending problem involves binary variables and bilinear terms, yielding a nonconvex MINLP. In this work we present two major contributions for the global solution ...

For optimal operation of power-intensive plants, production scheduling and electricity procurement have to be considered simultaneously. In addition, uncertainty needs to be taken...

Goldreich, Sahai, and Vadhan (CRYPTO 1999) proved that the promise problem for estimating the Shannon entropy of a distribution sampled by a given circuit is NISZK-complete. We co...
The PCP theorem (Arora et. al., J. ACM 45(1,3)) asserts the existence of proofs that can be verified by reading a very small part of the proof. Since the discovery of the theorem...
