  text: The role of information and communication technology for economic growth has
    been emphasized repeatedly. Technological breakthroughs have generated new forms
    of services, such as self-services or remote services. Although these encounters
    are qualitatively different from traditional service provision, prior service
    management literature thus far had paid little attention to theory development
    and the systematization of technology-based service encounters. To fill this research
    gap, the present study outlines how new types of technology-based services fit
    into existing service typologies and provides an extension of existing frameworks
    to capture their unique characteristics. These insights in turn offer managerial
    implications and highlight open research questions.

  text: To optimize the ultrasound irradiation for cavitation based ultrasound applications
    like sonochemistry or ultrasound cleaning, the correlation between cavitation
    intensity and the resulting effect on the process is of interest. Furthermore,
    changing conditions like temperature and pressure result in varying acoustic properties
    of the liquid. That might necessitate an adaption of the ultrasound irradiation.
    To detect such changes during operation, process monitoring is desired. Labor
    intensive processes, that might be carried out for several hours, also require
    process monitoring to increase their reliability by detection of changes or malfunctions
    during operation. In some applications cavitation detection and monitoring can
    be achieved by the application of sensors in the sound field. Though the application
    of sensors is possible, this necessitates modifications on the system and the
    sensor might disturb the sound field. In other applications harsh, process conditions
    prohibit the application of sensors in the sound field. Therefore alternative
    techniques for cavitation detection and monitoring are desired. The applicability
    of an external microphone and a self-sensing ultrasound transducer for cavitation
    detection were experimentally investigated. Both methods were found to be suitable
    and easily applicable.

  text: Self-optimizing mechatronic systems are a new class of technical systems.
    On the one hand, new challenges regarding dependability arise from their additional
    complexity and adaptivity. On the other hand, their abilities enable new concepts
    and methods to improve the dependability of mechatronic systems. This paper introduces
    a multi-level dependability concept for selfoptimizing mechatronic systems and
    shows how probabilistic planning can be used to improve the availability and reliability
    of systems in the operating phase. The general idea to improve the availability
    of autonomous systems by applying probabilistic planning methods to avoid energy
    shortages is exemplified on the example of an innovative railway vehicle.

  text: In this paper we propose an approach to retrieve the geometry of an acoustic
    sensor network consisting of spatially distributed microphone arrays from unconstrained
    speech input. The calibration relies on Direction of Arrival (DoA) measurements
    which do not require a clock synchronization among the sensor nodes. The calibration
    problem is formulated as a cost function optimization task, which minimizes the
    squared differences between measured and predicted observations and additionally
    avoids the existence of minima that correspond to mirrored versions of the actual
    sensor orientations. Further, outlier measurements caused by reverberation are
    mitigated by a Random Sample Consensus (RANSAC) approach. The experimental results
    show a mean positioning error of at most 25 cm even in highly reverberant environments.

  text: An intentional positioning of optically active quantum dots using site-selective
    growth by a combination of molecular beam epitaxy (MBE) and focused ion beam (FIB)
    implantation in an all-ultra-high-vacuum (UHV) setup has been successfully demonstrated.
    A square array of periodic holes on GaAs substrate was fabricated with FIB of
    30 keV ions followed by an in situ annealing step. Subsequently, the patterned
    holes were overgrown with an optimized amount of InAs in order to achieve site-selective
    growth of the QDs on the patterned holes. Under well-optimized conditions, a selectivity
    of single quantum dot growth in the patterned holes of 52% was achieved. Thereafter,
    carrier injection and subsequent radiative recombination from the positioned InAs/GaAs
    self-assembled QDs was investigated by embedding the QDs in the intrinsic part
    of a GaAs-based p–i–n junction device. Electroluminescence spectra taken at 77
    K show interband transitions up to the fifth excited state from the QDs.

  text: Self-optimizing systems are able to adapt their behavior autonomously according
    to their current self-determined objectives. Unforeseen influences could lead
    to dependability-critical behavior of the system. Methods are required which secure
    self-optimizing systems during operation. These methods to increase the dependability
    of the system should already be taken into consideration in the design process.
    This paper presents a guideline for the dependability-oriented design of self-optimizing
    systems, which integrates established classical methods like failure mode and
    effects analysis as well as methods based on self-optimization. On the one hand
    self-optimization is used to increase the dependability of the system by integrating
    objectives like safety, availability, and reliability to the objectives of the
    system. On the other hand methods are required to ensure the self-optimization
    itself. As basis for this guideline serves the principle solution of the system.
    The six phases of the guideline extend the design process and lead to an enhanced
    principle solution. Additionally, the guideline illustrates phases to implement
    and validate the self-optimizing system. The proposed guideline is applied to
    an innovative rail-bound vehicle, called RailCab, which is equipped with self-optimizing
    function modules.

  text: Recent advances in information processing enable new kinds of technical systems,
    called self-optimizing systems. These systems are able to adapt their objectives
    and their behavior according to the current situation and influences autonomously.
    This behavior adaptation is non-deterministic and hence self-optimization is a
    risk to the system, e.g. if the result of the self-optimization process does not
    match the suddenly changed situation. In contrary, self-optimization could be
    used to increase the dependability by pursuing objectives like reliability and
    availability. In our preceding publications we introduced the so called multi-level
    dependability concept to cope with this new kind of systems (cf. [6]). This concept
    comprises the monitoring of the system behavior, the classification of the current
    situation, and the selection of the appropriate measure, if reliability limits
    are exceeded. In this paper we present for the first time experimental results.
    The dependability concept is implemented in the self-optimizing active guidance
    system of a railway vehicle. The test drives illustrate clearly that the proposed
    concept is able to cope with, e.g., sensor failures, and is able to increase the
    reliability and availability of the active guidance module.

  text: Self-optimizing mechatronic systems are a new class of technical systems.
    On the one hand, new challenges regarding dependability arise from their additional
    complexity and adaptivity. On the other hand, their abilities enable new concepts
    and methods to improve the dependability of mechatronic systems. This paper introduces
    a multi-level dependability concept for self-optimizing mechatronic systems and
    shows how planning can be used to improve the availability and reliability of
    systems in the operating stages.

  text: New mechatronic systems, called self-optimizing systems, are able to adapt
    their behavior according to environmental, user and system specific influences.
    Self-optimizing systems are complex and due to their non-deterministic behavior
    comprise hidden risks, which cannot be foreseen in the design phase of the system.
    Therefore, this paper presents modifications of the current condition monitoring
    policy, to be able to cope with this new kind of systems. Beside avoiding critical
    situations evoked by self-optimization, the proposed concept uses self-optimization
    to increase the dependability of the system. In this case, the concept is applied
    to the active guidance module of an innovative rail-bound vehicle.

  text: Microphone arrays represent the basis for many challenging acoustic sensing
    tasks. The accuracy of techniques like beamforming directly depends on a precise
    knowledge of the relative positions of the sensors used. Unfortunately, for certain
    use cases manually measuring the geometry of an array is not feasible due to practical
    constraints. In this paper we present an approach to unsupervised shape calibration
    of microphone array networks. We developed a hierarchical procedure that first
    performs local shape calibration based on coherence analysis and then employs
    SRP-PHAT in a network calibration method. Practical experiments demonstrate the
    effectiveness of our approach especially for highly reverberant acoustic environments.

  text: 'In neurosurgery, delineation of tumor boundaries during resection of brain
    tumors is of substantial relevance. During operation distinction between tumor
    and healthy tissue rely on the abilities of the surgeon based on visual and tactile
    differentiation. In this paper a high sensitivity actuator-sensor system using
    a piezoelectric bimorph is presented. Frequency shift and transfer function of
    the bimorphpsilas voltages are detected and evaluated. Sensorpsilas sensitivity
    is evaluated using two frequency controls strategies: A phase-locked loop (PLL)
    and a self-oscillating circuit. Results of measurements conducted on gel-phantoms
    are presented and discussed.'
