  text: This work discusses the additive manufacturing of an axicon lens using cyclic
    olefin copolymer (TOPAS), and its characterization between 100 GHz and 300 GHz.
    The proposed manufacturing process followed by dip-coating post-processing provides
    an improved surface finish. Additionally, the terahertz output of the lens remains
    intact over the entire frequency range.

  text: <jats:p>consuming and often performed rather empirically. Efficient optimization
    of multiple objectives such as process time, viable cell density, number of operating
    steps &amp; cultivation scales, required medium, amount of product as well as
    product quality depicts a promising approach. This contribution presents a workflow
    which couples uncertainty-based upstream simulation and Bayes optimization using
    Gaussian processes. Its application is demonstrated in a simulation case study
    for a relevant industrial task in process development, the design of a robust
    cell culture expansion process (seed train), meaning that despite uncertainties
    and variabilities concerning cell growth, low variations of viable cell density
    during the seed train are obtained. Compared to a non-optimized reference seed
    train, the optimized process showed much lower deviation rates regarding viable
    cell densities (&lt;10% instead of 41.7%) using five or four shake flask scales
    and seed train duration could be reduced by 56 h from 576 h to 520 h. Overall,
    it is shown that applying Bayes optimization allows for optimization of a multi-objective
    optimization function with several optimizable input variables and under a considerable
    amount of constraints with a low computational effort. This approach provides
    the potential to be used in the form of a decision tool, e.g., for the choice
    of an optimal and robust seed train design or for further optimization tasks within
    process development.

  text: n order to ensure the safety and security of industrial systems with regard
    to all life cycle phases from development through operation to disposal, specific
    regulatory and normative requirements are imposed. Due to the digitalization,
    interconnection, and constantly increasing complexity of manufacturing systems
    in the context of Industrie 4.0, the manual effort necessary to achieve the required
    safety and security is becoming ever greater and almost impossible to manage,
    especially for small and medium-sized enterprises. Therefore, this paper examines
    the existing challenges in this area in more detail and gives an outlook on the
    possible solutions to ensure safety and security much quicker and with less manual
    effort. The overall vision is a (partially) automated risk assessment of modular
    systems with respect to safety and security, including the alignment of the corresponding
    processes from both domains and the formalization of the information models needed.

  text: Metalimnetic oxygen minima are observed in many lakes and reservoirs, but
    the mechanisms behind this phenomena are not well understood. Thus, we simulated
    the metalimnetic oxygen minimum (MOM) in the Rappbode Reservoir with a well-established
    two-dimensional water quality model (CE-QUAL-W2) to systematically quantify the
    chain of events leading to its formation. We used high-resolution measured data
    to calibrate the model, which accurately reproduced the physical (e.g. water level
    and water temperature), biogeochemical (e.g. nutrient and oxygen dynamics) and
    ecological (e.g. algal community dynamics) features of the reservoir, particularly
    the spatial and temporal extent of the MOM. The results indicated that around
    60% of the total oxygen consumption rate in the MOM layer originated from benthic
    processes whereas the remainder originated from pelagic processes. The occurrence
    of the cyanobacterium Planktothrix rubescens in the metalimnion delayed and slightly
    weakened the MOM through photosynthesis, although its decaying biomass ultimately
    induced the MOM. Our research also confirmed the decisive role of water temperature
    in the formation of the MOM since the water temperatures, and thus benthic and
    pelagic oxygen consumption rates, were higher in the metalimnion than in the hypolimnion.
    Our model is not only providing novel conclusions about the drivers of MOM development
    and their quantitative contributions, it is also a new tool for understanding
    and predicting ecological and biogeochemical water quality dynamics.

  text: Discerning unexpected from expected data patterns is the key challenge of
    anomaly detection. Although a multitude of solutions has been applied to this
    modern Industry 4.0 problem, it remains an open research issue to identify the
    key characteristics subjacent to an anomaly, sc. generate hypothesis as to why
    they appear. In recent years, machine learning models have been regarded as universal
    solution for a wide range of problems. While most of them suffer from non-self-explanatory
    representations, Gaussian Processes (GPs) deliver interpretable and robust statistical
    data models, which are able to cope with unreliable, noisy, or partially missing
    data. Thus, we regard them as a suitable solution for detecting and appropriately
    representing anomalies and their respective characteristics. In this position
    paper, we discuss the problem of automatic and interpretable anomaly detection
    by means of GPs. That is, we elaborate on why GPs are well suited for anomaly
    detection and what the current challenges are when applying these probabilistic
    models to large-scale production data.

  text: Increasingly, production processes are enabled and controlled by Information
    Technology (IT), a development being also referred to as “Industry 4.0”. IT thereby
    contributes to flexible and adaptive production processes, and in this sense factories
    become “smart factories”. In line with this, IT also more and more supports human
    workers via various assistance systems. This support aims to both support workers
    to better execute their tasks and to reduce the effort and time required when
    working. However, due to the large spectrum of assistance systems, it is hard
    to acquire an overview and to select an adequate system for a smart factory based
    on meaningful criteria. We therefore synthesize a set of comparison criteria into
    a consistent framework and demonstrate the application of our framework by classifying
    three examples.

  text: Catchwords such as “Cyber-Physical-Systems” and “Industry 4.0” describe the
    current development of systems with embedded intelligence. These systems can be
    characterized by an increasing technical complexity that must be addressed in
    the user interface. In this paper we analyze the specific requirements posed by
    the interaction with cyber-physical-systems, present a coordinated approach to
    these requirements and illustrate our approach with a practical example of an
    assistance system for assembly workers in an industrial production environment.

  text: Cognitive radios (CR) can sense and detect temporarily available spectral
    holes for an opportunistic operation to improve the spectral efficiency and coexistence
    of industrial radio systems. It will be of particular interest for a CR system
    to apply predictive modeling in order to forecast the behavior of the coexisting
    environment. A secondary cognitive user shall use preemptive tuning of its operating
    parameters following the predictive model. However, a considerable challenge is
    to generate an accurate model and predict efficiently in order to meet strict
    time related requirements of industrial applications. Such predictive modeling
    has already gained some attention but real-time experimental results have never
    been reported to the best of our knowledge. In this contribution we investigate
    the performance of a Markov model based CR system using simulative and experimental
    environments for its application in industrial systems.
