  text: With enhancing digitalization, condition monitoring is used in an increasing
    number of application fields across various industrial sectors. By its application,
    increased reliability as well as reduced risks and costs can be achieved. Based
    on different approaches, technical systems are monitored and measured data is
    analyzed to enable condition-based or predictive maintenance. To this end, machine
    learning approaches are usually implemented to diagnose the health states or predict
    the health index of the monitored system. However, these trained models are often
    black-box models, not intuitively explainable for a human. To overcome this shortcoming,
    a model-based approach based on physics is developed for piezoelectric bending
    actuators. Such a model enables a transparent representation of the system. Moreover,
    the model-based approach is extended by a parameter-estimation to account for
    sudden changes in behavior e. g. caused by occurring cracks.

  text: Piezoelectric inertia motors use the inertia of a body to drive it by means
    of a friction contact in a series of small steps. These motors can operate in
    ``stick-slip'' or ``slip-slip'' mode, with the fundamental frequency of the driving
    signal ranging from several Hertz to more than 100 kHz. To predict the motor characteristics,
    a Coulomb friction model is sufficient in many cases, but numerical simulation
    requires microscopic time steps. This contribution proposes a much faster simulation
    technique using one evaluation per period of the excitation signal. The proposed
    technique produces results very close to those of timestep simulation for ultrasonics
    inertia motors and allows direct determination of the steady-state velocity of
    an inertia motor from the motion profile of the driving part. Thus it is a useful
    simulation technique which can be applied in both analysis and design of inertia
    motors, especially for parameter studies and optimisation.

  text: The paper presents the results of numerical and experimental investigation
    of cylindrical piezoelectric actuator used for achieving independent three degrees
    of freedom oscillations of the contact point. The design of actuator based on
    a hollow piezoelectric cylinder mounted on a metal rod. The piezoceramic cylinder
    has a radial polarization and special configuration of the electrodes that cover
    inner and outer surface of the cylinder. The main advantage of actuator's design
    is that solid metallic rod operates as a part of inner electrode of the cylinder
    and a stator of actuator. The geometry of piezoelectric actuator was adopted to
    reach resonance of oscillations for the first longitudinal mode and the third
    flexural mode at same frequency. The actuator is designed to move positioned object
    through contact point which is located on the top of the rod. The optimal topology
    of electrodes was found to achieve longitudinal and flexural oscillations of the
    actuator in two perpendicular planes. Three degrees of freedom of the positioning
    object can be achieved and control of the system can be implemented by applying
    different excitation schemes and regimes. The numerical simulation and experimental
    study of piezoelectric actuator was performed. Impedance of actuator was analyzed
    under different excitation regimes. The results of numerical modeling and experimental
    study were compared. Recommendations for the further development of this type
    of actuator are given.

  text: "EN: Although the use of new actuator technologies is quite enthusiastic,
    the realization of innovative systems based on these principles fails because
    of doubts in dependability. Until now, new working principles for actuators have
    not been systematically investigated in the means of dependability. Therefore
    we developed a proceeding for a dependability-oriented evaluation of technologies.
    This is shown in the case of shape memory alloy actuators. \r\nDE: Die Realisierung
    von Systemen mittels innovativer Aktortechnologien scheitert oftmals an der Skepsis
    gegenüber der Verlässlichkeit (Vertrauen in die zuverlässige und sichere Funktionalität
    der Technologie). Diese liegt darin begründet, dass neue Aktortechnologien bzw.
    die Integration von innovativen physikalischen Wirkprinzipen innerhalb neuer Aktorkonzepte
    bisher noch nicht systematisch im Kontext der Verlässlichkeit untersucht werden.
    Daher haben wir ein Vorgehen zur verlässlichkeitsorientierten Technologiebewertung
    entwickelt. Neben der detaillierten Darstellung des Vorgehensmodells wird es exemplarisch
    anhand von Formgedächtnislegierungen zur Entwicklung innovativer Antriebslösungen
    angewendet."

    tumors is of substantial relevance. During operation distinction between tumor
