The task of privacy amplification, in which Alice holds some partially secret information with respect to an adversary Eve and wishes to distill it until it is completely secret, is known to be solvable almost optimally in both the classical and quantum worlds. Unfortunately, when considering an adversary who is limited only by non-signalling constraints such a statement cannot be made in gener...

Abstrsct--This paper presents a numerical technique for solving non-linear constrained optimal control problems. The method extends previous contributions to non-linear unconstrained optimal control problems and is based upon a Chebyshev series expansion of state and control. The differential and integral expressions from the system dynamics and the performance index, the boundary conditions an...

The uplink-downlink duality is reviewed with regard to constraints imposed on the transmission schemes in practice. In particular, the effects of non-Gaussian signaling, the use of implementable precoding schemes, and the availability of only imperfect channel state information at the central base-station are analyzed and discussed. The sources for violating the uplink-downlink duality in pract...

Economic dispatch (ED) has been considered to be one of the key functions in electric power system operation which can help to build up effective generating management plans. The practical ED problem has non-smooth cost function with nonlinear constraints which make it difficult to be effectively solved. This paper presents a novel heuristic and efficient optimization approach based on the new ...

Within the project RECLAF (Resource Classification Framework for Old Landfills in Flanders) the resource recovery potential of approximately 2,000 historic landfills in Flanders is prospected. The research project’s goal is to systematically provide information for the future management of these former landfill sites, e.g. whether the sites are to be mined or not and under which conditions. The...

This paper reports an experiment in which subjects buy and sell lotteries in repeated markets under symmetric and asymmetric information. In the markets with asymmetric information a minority of the subjects, the informed, were given extra information about the lottery’s payout, so had an informational advantage over the majority, the uninformed. In the markets with symmetric information none o...

This study demonstrates an investigation of the external corporate governance effect short selling mechanisms on firm value in Chinese context. The family businesses is also examined as a moderator relationship between short-selling and value. Using panel data analysis listed companies, this paper tests total sample 22,468 firm-year observations from Shanghai Shenzhen Stock Exchange 2009 to 201...
