Information-theoretical meaning of quantum dynamical entropy
The theory of noncommutative dynamical entropy and quantum symbolic dynamics
for quantum dynamical systems is analised from the point of view of quantum
information theory. Using a general quantum dynamical system as a communication
channel one can define different classical capacities depending on the
character of resources applied for encoding and decoding procedures and on the
type of information sources. It is shown that for Bernoulli sources the
entanglement-assisted classical capacity, which is the largest one, is bounded
from above by the quantum dynamical entropy defined in terms of operational
partitions of unity. Stronger results are proved for the particular class of
quantum dynamical systems -- quantum Bernoulli shifts. Different classical
capacities are exactly computed and the entanglement-assisted one is equal to
the dynamical entropy in this case.Comment: 6 page

Applying multiobjective evolutionary algorithms in industrial projects
During the recent years, multiobjective evolutionary algorithms have matured as a flexible optimization tool which can be used in various areas of reallife applications. Practical experiences showed that typically the algorithms need an essential adaptation to the specific problem for a successful application. Considering these requirements, we discuss various issues of the design and application of multiobjective evolutionary algorithms to real-life optimization problems. In particular, questions on problem-specific data structures and evolutionary operators and the determination of method parameters are treated. As a major issue, the handling of infeasible intermediate solutions is pointed out. Three application examples in the areas of constrained global optimization (electronic circuit design), semi-infinite programming (design centering problems), and discrete optimization (project scheduling) are discussed
Structured pseudospectra and random eigenvalues problems in vibrating systems
This paper introduces the concept of pseudospectra as a generalized tool for uncertainty quantification and
propagation in structural dynamics. Different types of pseudospectra of matrices and matrix polynomials are
explained. Particular emphasis is given to structured pseudospectra for matrix polynomials, which offer a
deterministic way of dealing with uncertainties for structural dynamic systems. The pseudospectra analysis is
compared with the results from Monte Carlo simulations of uncertain discrete systems. Two illustrative example
problems, one with probabilistic uncertainty with various types of statistical distributions and the other with interval
type of uncertainty, are studied in detail. Excellent agreement is found between the pseudospectra results and Monte
Carlo simulation results
