  text: Das Spektrum akustischer Wellenleiter zur Flüssig-keitscharakterisierung reicht
    von der Seismologie und Geophysik mit Wellenleiterdimensionen von einigen km über
    die zerstörungsfreie Prüfung bis hin zur Prozessmesstechnik mit Sensordimensio-nen
    von wenigen mm. In diesem Beitrag wird ein phänomenologischer Weg zur Klassifizierung
    der Wellenleiter entwickelt, wobei stets die Oberflä-chenauslenkungen an der Wellenleitergrenze
    und die Anzahl der an der Wellenausbreitung beteiligten Moden Berücksichtigung
    finden. Im weiteren Verlauf werden Möglichkeiten zur Modellierung, Simulation
    und Messung multimodaler Wellenausbreitung im akustischen Wellenleiter gezeigt.

  text: Es wird ein Wellenleiter basiertes Messsystem vorgestellt, mit dem anhand
    einer einzigen Transmissionsmessung alle Daten bestimmt werden können, die zur
    Simulation von Schallausbreitungsphänomenen in stark absorbierenden und schwach
    anisotropen Materialien erforderlich sind. Auf diese Weise ist es fortan möglich
    die akustischen Kenngrößen (winkel- und frequenzabhängige Schallgeschwindigkeiten
    und frequenzabhängige Absorption) verschieden konditionierter Materialproben (Temperatur,
    Feuchtigkeit, Alter) simultan zu erfassen. Genutzt wird dazu die mehrmalige Modekonversion
    an den Mantelflächen eines hohlzylindrischen akustischen Wellenleiters, wonach
    ein Empfangssignal mehrere Signalgruppen aufweist, deren absolute Laufzeit, Laufzeitdifferenzen
    und Amplituden in Abhängigkeit der Materialkenngrößen stark variieren. Grundlegend
    für die realisierte und in diesem Beitrag beschriebene inverse Bestimmung der
    akustischen Kenngrößen ist ein ganzheitliches Modell der Schallanregung, -ausbreitung
    und -detektion, welches die schnelle Berechnung der Empfangssignale erlaubt. Die
    gezielte Variation der Modell-Eingangsgrößen führt schließlich zu einer bestmöglichen
    Übereinstimmung zwischen berechneten und gemessenen Empfangssignalen, sodass die
    final angesetzten Modell-Eingangsgrößen eine gute Approximation der gesuchten
    materialspezifischen akustischen Kenngrößen darstellen. Im Rahmen dieses Beitrags
    werden der Messaufbau, wesentliche Teile der Modellierung sowie die grundätzliche
    Vorgehensweise zur Anwendung der inversen Messmethode gezeigt. Anhand gemessener,
    berechneter und mittels Finiter Elemente Methode simulierter Signale wird das
    Verfahren für einen Werkstoff, spritzgegossenes Polypropylen, demonstriert.

  text: If a guided Lamb wave leaks energy from a plate into a surrounding fluid,
    the radiated almost plane wave has a frequency dependent angle towards the boundary.
    This radia- tion angle can be calculated by numerical determination of the plates'
    phase velocities. We also measured the radiation angle in Schlieren photographs
    and found a mentionable discrepancy to the calculated angles in certain frequency
    regions. A first approach by modifying the boundary condition could not re- solve
    the observed discrepancies, but a reinterpretation of the Schlieren photographs
    as interference patterns of different Leaky Lamb waves leads to a good correspondence
    between measured and calculated values.

  text: Bei der Ultraschall-basierten Abstandsmessung mit einem einzelnen Schallwandler
    ergibt sich durch das Prinzip bedingt eine Blindzone. Während und unmittelbar
    nach der Anregung durch das Sendesignal ist es im Allgemeinen nicht möglich, das
    Empfangssignal am Ultraschallwandler auszuwerten. Eine Verwendung von codierten
    Sendesignalen (z.B. zur Unterscheidung verschiedener Sensoren) verlängert diesen
    Blindbereich zusätzlich. Dieser Beitrag zeigt eine Möglichkeit zur Realisierung
    eines simultanen Sende- und Empfangsbetriebs mit einem einzelnen Schallwandler.
    Dadurch wird es möglich, die Blindzone auch bei sehr langen Sendesignalen zu eliminieren.
    Dazu wird der Ultraschallwandler über einen Vorwiderstand betrieben und dessen
    Spannung gemessen. Mittels eines mathematischen Modells kann das elektrische Sendesignal,
    welches am Ultraschallwandler anliegt, bestimmt werden. Die Subtraktion dieses
    Signals von der gemessenen Schallwandlerspannung liefert das elektrische Empfangssignal.
    Aufgrund von z.B. Temperatureinflüssen ändern sich die elektrischen Eigenschaften
    des Ultraschallwandlers ständig, wodurch eine Anpassung des Modells notwendig
    wird. Daher kann die Modellidentifikation nicht im Vorfeld mit einer Freifeldmessung
    erfolgen, sondern ist permanent während des Betriebes notwendig. Tritt dabei ein
    Empfangssignal z.B. infolge einer Reflexion auf, so wird die Bestimmung der Modellparameter
    gestört. Durch eine Bewertung der ermittelten Modelle kann die Robustheit einer
    Abstandsmessung erhöht werden

  text: Ultraschall-Abstandssensoren besitzen meist nur einen Schallwandler und dadurch
    Prinzip bedingt einen Mindestabstand. Eine Möglichkeit diesen Mindestabstand zu
    reduzieren, besteht in der Realisierung eines simultanen Sendeund Empfangsbetriebes.
    In diesem Beitrag wird dies durch eine digitale Signalverarbeitung realisiert.
    Hierzu ist es notwendig, das Schallwandlersignal und das elektrische Sendesignal
    zu digitalisieren. Mit der Kenntnis des Schallwandlerverhaltens sowie des elektrischen
    Sendesignals wird das zu erwartende Schallwandlersignal modellbasiert berechnet
    und vom gemessenen Schallwandlersignal subtrahiert, um so das Empfangssignal zu
    bestimmen. Dabei liegen die Herausforderungen in der Ermittlung der Parameter
    eines repräsentativen Schallwandlermodells sowie der Gewährleistung einer robusten
    Echodetektion.

  text: Computer aided simulation of guided acoustic waves in single- or multilayered
    waveguides is an essential tool for several applications of acoustics and ultrasonics
    (i.e. pipe inspection, noise reduction). To simulate wave propagation in geometrically
    simple waveguides (plates or rods), one may employ the analytical global matrix
    method [1]. This requires the computation of all roots of the determinate of a
    certain submatrix. The evaluation of all real or even complex roots is actually
    the methods most concerning restriction. Previous approaches base on so called
    mode-tracers which use the physical phenomenon that solutions (roots) appear in
    a certain pattern (waveguide modes) and thus use known solutions to limit the
    root finding algorithms searchspace with respect to consecutive solutions. As
    the limitation of searchspace might be unstable in some cases, we propose to replace
    the mode-tracer with a suitable version of an interval Newton method based on
    Intlab [2]. To apply this interval based method, we extended the interval and
    derivative computation provided by Intlab such that corresponding information
    is also available for Bessel functions used in the circular model (rods) of acoustic
    waveguides. We present numerical results of a simple acoustic waveguide and discuss
    extensions required for more realistic scenarios.

  text: The contribution presents the sensor application of a resonance-induced extraordinary
    transmission through a regular phononic crystal consisting of a metal plate with
    a periodic arrangement of holes in a square lattice at normal incidence of sound.
    The characteristic transmission peak has been found to strongly depend on sound
    velocity of the liquid the plate is immersed in. The respective peak maximum frequency
    can serve as measure for the concentration of a component in the liquid mixture,
    if a beneficial relation to the speed of sound of the liquid exists. Experimental
    verification has been performed with mixtures of water and propanol as model system.
    Here we especially pay attention to numerical calculations based on EFIT and COMSOL
    which reveal more insides to the wave propagation characteristics. Experimental
    investigations with Schlieren method and laser interferometry support the theoretical
    findings.

  text: challenge for the digital preservation community. While the methodological
    frameworks for selecting these properties provide a good foundation, a continued
    discussion is necessary for further clarifying and improving the available methods.
    This paper advances earlier work by building on the existing InSPECT framework
    and improving its capabilities of working with complex/compound objects like blogs.
    The modifications enable a more thorough analysis of object structures, accentuate
    the differences and similarities between the framework’s two streams of analysis
    (i.e. Object and Stakeholder analysis) and, subsequently, improve the final reformulation
    of the properties. To demonstrate the applicability of the modified framework,
    thepaper presents a use case of a blog preservation initiative that is informed
    by stakeholder interviews and evaluation of structural and technological foundations
    of blogs. It concludes by discussing the limitations of the approach and suggesting
    directions for future research.

  text: Communication within online social network applications enables users to express
    and share sentiments electronically. Existing studies examined the existence or
    distribution of sentiments in online communication at a general level or in small-observed
    groups. Our paper extends this research by analyzing sentiment exchange within
    social networks from an ego-network perspective. We draw from research on social
    influence and social attachment to develop theories of node polarization, balance
    effects and sentiment mirroring within communication dyads. Our empirical analysis
    covers a multitude of social networks in which the sentiment valence of all messages
    was determined. Subsequently we studied ego-networks of focal actors (ego) and
    their immediate contacts. Results support our theories and indicate that actors
    develop polarized sentiments towards individual peers but keep sentiment in balance
    on the ego-network level. Further, pairs of nodes tend to establish similar attitudes
    towards each other leading to stable and polarized positive or negative relationships

  text: Blogging has often been described as writing an online diary but, nowadays,
    it is more diverse and a considerable amount of blogs forms a common interconnected
    resource – the blogosphere – with comprehensive societal impact. While various
    studies have inquired social-psychological influenceson the intention to contribute
    to an individual blog, the perceptions related to creating such a common valuable
    good have not yet been focussed. Therefore, we introduce a new construct – the
    oeuvre of blogging – to better account for the notion of the blogosphere as a
    collective outcome. Furthermore, we propose a research model to inquire the influence
    of individual and collective beliefs on the oeuvre in comparison to short-term
    blogging activity. We conducted an online survey with 509 international distributed
    bloggers to test our model. The results of our study provide support for the importance
    of an oeuvre construct to explain influences on bloggers and blogging

  text: Communication in online social networks has been analyzed for some time regarding
    the expression of sentiments. So far, very little is known about the relationship
    between sentiments and network emergence, dissemination patternsand possible differences
    between positive and negative sentiments. The dissemination patterns analyzed
    in this study consist of network motifs based on triples of actors and the ties
    among them. These motifs are associated with common social network effects to
    derive meaningful insights about dissemination activities. The data basis includes
    several thousand social networks with textual messages classified according to
    embedded positive and negative sentiments. Based on this data, sub-networks are
    extracted and analyzed with a dynamic network motif analysis to determine dissemination
    patterns and associated network effects. Results indicate that the emergence of
    digital social networks exhibits a strong tendency towards reciprocity, followed
    by the dominance ofhierarchy as an intermediate step leading to social clustering
    with hubs and transitivity effects for both positive and negative sentiments to
    the same extend. Sentiments embedded in exchanged textual messages do only play
    a secondary role in network emergence and do not express differences regarding
    the emergence of network patterns.
