In this paper, we describe how to construct an efficient and unconditionally secure verifiable threshold changeable scheme, in which any participants can verify whether the share given by the dealer is correct or not, in which the combiner can verify whether the pooled shares are correct or not, and in which the threshold can be updated plural times to the values determined in advance. An optim...

In the past decades, the environment of production companies showed a permanent increase in dynamic and volatility in the form of demand fluctuations, new technologies or global crises. As a reaction to these new requirements, changeability of production systems came into attention. A changeable production system can adapt to these changes quickly and with little effort. Even though demand for ...

Face perception, perhaps the most highly developed visual skill in humans, is mediated by a distributed neural system in humans that is comprised of multiple, bilateral regions. We propose a model for the organization of this system that emphasizes a distinction between the representation of invariant and changeable aspects of faces. The representation of invariant aspects of faces underlies th...
