  text: Evolutionary algorithms based on edge assembly crossover (EAX) constitute
    some of the best performing incomplete solvers for the well-known traveling salesperson
    problem (TSP). Often, it is desirable to compute not just a single solution for
    a given problem, but a diverse set of high quality solutions from which a decision
    maker can choose one for implementation. Currently, there are only a few approaches
    for computing a diverse solution set for the TSP. Furthermore, almost all of them
    assume that the optimal solution is known. In this paper, we introduce evolutionary
    diversity optimisation (EDO) approaches for the TSP that find a diverse set of
    tours when the optimal tour is known or unknown. We show how to adopt EAX to not
    only find a high-quality solution but also to maximise the diversity of the population.
    The resulting EAX-based EDO approach, termed EAX-EDO is capable of obtaining diverse
    high-quality tours when the optimal solution for the TSP is known or unknown.
    A comparison to existing approaches shows that they are clearly outperformed by
    EAX-EDO.

  text: In this work, the preparation of porous hybrid particle-based films by core-shell
    particle design and convenient film preparation is reported. Monodisperse core
    particles consisting of poly(methyl methacrylate‑co‑allyl methacrylate) (P(MMA‑co‑ALMA))
    were synthesized by starved-feed emulsion polymerization followed by the introduction
    of an initiator-containing monomer (inimer) for subsequent atom transfer radical
    polymerization (ATRP). The inimer shell allowed for the introduction of allylhydrido
    polycarbosilane (SMP-10) under ATRP conditions by grafting to the core particles.
    The functionalization of the prepared core-shell particles was investigated by
    IR spectroscopy (FTIR), scanning transmission electron microscopy (STEM) and solid-state
    NMR combined with dynamic nuclear polarization (DNP). The obtained hard core/soft
    preceramic shell particles were subjected to the melt-shear organization technique,
    enabling a convenient alignment into a colloidal crystal structure in one single
    step without the presence of a dispersion medium or solvent for the designed particles.
    Moreover, the hybrid particle-based films were converted into a porous ceramic
    structure upon thermal treatment. As a result, freestanding ceramic porous films
    have been obtained after degradation of the organic template core particles. Noteworthy,
    the conversion of the matrix material consisting of SMP-10 into the ceramic occurred
    with preservation of the pristine colloidal crystal template structure. Herein,
    the first example of core-shell particle preparation by combining different polymerization
    methodologies and application of the convenient melt-shear organization technique
    is shown, paving a new way to ceramic materials with tailored morphology and porosity.

  text: The utilization and preparation of functional hybrid films for optical sensing
    applications and membranes is of utmost importance. In this work, we report the
    convenient and scalable preparation of self-crosslinking particle-based films
    derived by directed self-assembly of alkoxysilane-based cross-linkers as part
    of a core-shell particle architecture. The synthesis of well-designed monodisperse
    core-shell particles by emulsion polymerization is the basic prerequisite for
    subsequent particle processing via the melt-shear organization technique. In more
    detail, the core particles consist of polystyrene (PS) or poly(methyl methacrylate)
    (PMMA), while the comparably soft particle shell consists of poly(ethyl acrylate)
    (PEA) and different alkoxysilane-based poly(methacrylate)s. For hybrid film formation
    and convenient self-cross-linking, different alkyl groups at the siloxane moieties
    were investigated in detail by solid-state Magic-Angle Spinning Nuclear Magnetic
    Resonance (MAS, NMR) spectroscopy revealing different crosslinking capabilities,
    which strongly influence the properties of the core or shell particle films with
    respect to transparency and iridescent reflection colors. Furthermore, solid-state
    NMR spectroscopy and investigation of the thermal properties by differential scanning
    calorimetry (DSC) measurements allow for insights into the cross-linking capabilities
    prior to and after synthesis, as well as after the thermally and pressure-induced
    processing steps. Subsequently, free-standing and self-crosslinked particle-based
    films featuring excellent particle order are obtained by application of the melt-shear
    organization technique, as shown by microscopy (TEM, SEM).

  text: Self-assembly of nanoparticles (NPs) forming unique structures has been investigated
    extensively over the past few years. However, many self-assembled structures by
    NPs are irreversible, because they are generally constructed using their suspensions.
    It is still challenging for NPs to reversibly self-assemble in dry state, let
    alone of polymeric NPs with general sizes of hundreds of nm. Herein, this study
    reports a new reversible self-assembly phenomenon of NPs in dry state, forming
    thermoreversible strip-like supermolecular structures. These novel NPs of around
    150 nm are perfluorinated surface-undecenoated cellulose nanoparticles (FSU-CNPs)
    with a core-coronas structure. The thermoreversible self-assembled structure is
    formed after drying in the air at the interface between FSU-CNP films and Teflon
    substrates. Remarkably, the formation and dissociation of this assembled structure
    are accompanied by a reversible conversion of the surface hydrophobicity, film
    transparency, and anisotropic properties. These findings show novel feasibility
    of reversible self-assembly of NPs in dry state, and thereby expand our knowledge
    of self-assembly phenomenon.

  text: In forced systems with cyclic symmetry localization can occur due toparameter
    uncertainties. Often, Monte-Carlo simulations are used to findregions, where the
    system response is sensitive to parameteruncertainties. These simulations require
    a large computation time.Therefore, an approximate method to calculate the envelopes
    of thefrequency response functions is developed in this paper. An example of anonlinear
    system with cyclic symmetry is a bladed disk assembly withfriction dampers. Friction
    dampers can be installed underneath the bladeplatforms of turbine blades. Due
    to dry friction and the relative motionbetween blades and dampers, energy is dissipated,
    which results in areduction of blade vibration amplitudes. By optimizing the mass
    of thefriction dampers, the best damping effects are obtained, which lead toan
    increase in the reliability of the turbine. In this paper, thecalculated response
    of a mistuned bladed disk assembly with frictiondampers is discussed. An approximate
    method is developed to calculatethe envelopes of the corresponding frequency response
    function forstatistically varying eigenfrequencies of the blades. Regions wherelocalization
    can occur with a high probability, are calculated by thismethod.

- lang: eng
  text: The main goal of the article is to evaluate the suitability of visual programming
    languages, i.e., Pictorial Janus (K. Kahn and V. Saraswat, 1990), for the modeling
    of complex systems and their control strategies. These systems can be seen as
    networks of communicating objects. Objects select strategies for suitable actions
    based on incoming messages. Our field of investigation is in computer integrated
    manufacturing considering the example of a car manufacturing cell. This color
    sorting assembly buffer (CSAB) schedules jobs in queues. The jobs represent car
    bodies scheduled in feeder lines for the enameling. Feeder lines collect raw bodies
    to blocks. Blocks are bodies which are to be enameled by the same color. This
    organization decreases the cost of expensive change-over-times when changing colors
    at the enamelling. Blocks of bodies are dislocated from the queue and enameled
    successively. Contradictory system goals, such as minimizing color changes and
    preserving the sequence of incoming jobs, have to be regarded by appropriate control
    strategies. Due to the complexity of this (NP complete) problem and to real time
    requirements for online control there are no optimal strategies on hand. Consequently,
    suitable heuristics have to be developed. Often they are designed applying a trial-and-error
    method. A modeling framework has to support the rapid prototyping of these systems
    as well as an expressive end user oriented representation. Both are essential
    requirements since end users need other visualization techniques than experienced
    designers due to their different knowledge and interests.
