  text: In this paper we propose a novel adaptation algorithm for Filter-and-Sum beamforming
    in spatially correlated noise. Deterministic and stochastic gradient ascent algorithms
    are derived from a constrained optimization problem, which iteratively estimate
    the principal eigenvecto r of a generalized eigenvalue problem. The method does
    not require an explicit estimation of the speaker location. It is shown that the
    well-known Delay-and-Sum beamformer and the previously introduced Filter-and-Sum
    beamformer in spatially white noise are obtained as special cases. Further, bounds
    on the maximally achievable SNR gains are derived and it is shown that the proposed
    adaptation algorithm is able to approach these performance bounds.

  text: The transmission errors in a wireless or packet oriented network may dramatically
    decrease the performance of a distributed speech recognition DSR) system. Error
    concealment has been shown to be an effective way to mantain an acceptable word
    error rate when dealing with error prone communication channels. In this paper
    we propose an extension of our previously introduced soft features approach for
    the case that the soft-output of the channel decoder is not available at the server
    side of the DSR system. We found a simple method to estimate bit reliability information
    which still gives good speech recognition results. It is shown that some other
    error concealment schemes turn out to be special cases of the method proposed
    here.

  text: 'In this paper we present a comparison of the recently proposed Soft-Feature
    Distributed Speech Recognition (SFDSR) with the two evaluated candidate codecs

  text: For human-machine interfaces in distant-talking environments multichannel
    signal processing is often employed to obtain an enhanced signal for subsequent
    processing. In this paper we propose a novel adaptation algorithm for a filter-and-sum
    beamformer to adjust the coefficients of FIR filters to changing acoustic room
    impulses, e.g. due to speaker movement. A deterministic and a stochastic gradient
    ascent algorithm are derived from a constrained optimization problem, which iteratively
    estimates the eigenvector corresponding to the largest eigenvalue of the cross
    power spectral density of the microphone signals. The method does not require
    an explicit estimation of the speaker location. The experimental results show
    fast adaptation and excellent robustness of the proposed algorithm.

  text: Impulsbasierte Ultraschallsensorsysteme zur Messung von Füllstand, Durchfluss
    und Konzentration sind heutzutage aufgrund ihrer Robustheit und Wartungsfreundlichkeit
    weit verbreitet. Probleme treten immer dann auf, wenn sich Gasblasen im Medium
    befinden. Diese verändern das empfangene Signal derart, dass eine exakte Messung
    der Schallgeschwindigkeit des flüssigen Mediums nicht mehr möglich ist. Dieser
    Beitrag behandelt eine neue Art der Signalauswertung, die eine zuverlässige Bestimmung
    der Schallgeschwindigkeit auch in diesem Fall gewährleistet. Darüber hinaus können
    auch Rückschlüsse auf den Gasanteil innerhalb des flüssigen Mediums gewonnen werden.

  text: Currently there are pulse based ultrasonic sensor systems used to measure
    flow, liquid level, concentration or in process monitoring. In several processes
    the investigated media are a mixture of liquid and solid ingredients (emulsions,
    suspensions). The use of ultrasonic sensor systems will be very complicated if
    gas bubbles appear at the measurement place caused by chemical reactions, high
    temperature or fast flow that means by typical process conditions. Firstly, the
    appearance of gas bubbles falsifies the measured absorption. Secondly, the measured
    velocity is influenced by gas bubbles. In figure 1 is visible that a volume fraction
    of 0.1 ppm of undissolved air decreases the sound velocity by 1.4 m s-1

  text: In vielen verfahrenstechnischen Prozessen ist die kontinuierliche Regelung
    von Prozessgrößen für einen stabilen und sicheren Betrieb eine wichtige Vorraussetzung.
    Die Erfassung der Zielgrößen geschieht aufgrund von hoher Robustheit und Wartungsfreundlichkeit
    zunehmend mit akustischen Messverfahren. Besonders impulsbasierte Messsysteme
    werden häufig zur Messung von Durchfluss, Füllstand und in der Flüssigkeitsanalytik
    auch zur Konzentrationsmessung benutzt. Dabei führen am Messort auftretende Gasblasen
    zu großen messtechnischen Problemen. Sie verändern die gemessenen akustischen
    Stoffkenngrößen, wodurch es zur fehlerhaften Regelung bestimmter Prozesszielgrößen
    kommt.

  text: Today headlights are built with transparent polycarbonate front windows. If
    the air moisture inside the headlight is high and the outside temperature decreases
    below the dew-point, the air moisture condensates inside and the inner surface
    of the polycarbonate front window (PCFW) becomes nontransparent (figure 1). To
    the costumer this appears as an optical defect.In order to avoid the condensation
    and to speed up the evaporation of the condensed water (condensate) on the PCFW
    a Computational-Fluid-Dynamic-simulation is used. The simulation results are proceeded
    to optimise the airflow and the arrangement of the breather holes. An important
    problem is the validation of the simulated results with the reality. It was necessary
    to build a non-invasive measurement system for the continuous characterisation
    of condensated areas without affecting the material properties, the airflow and
    the light distribution inside the headlight.

  text: In the 1950's many investigations have been made in measuring the Young's
    and the shear modus of isotropic materials with acoustic waves. Therefore both
    the longitudinal and transversal sound velocities have been determined with only
    one specimen, that had to be large in comparison to the wavelength (Brown, Reynolds,
    Dunegan). Therewith the method was suited only for low absorbing materials. In
    the 1990's further developments led to mono mode rods to describe viscoelastic
    properties. Their diameters had to be very small for high frequencies, thus giving
    practical values up to 65 kHz (Benatar). This contribution is about a tubular
    multi mode specimen and its application for the simultaneous measurement of the
    abovementioned acoustic properties at high frequencies.

  text: "In den bekannten grundlegenden Ausf¨uhrungen zur Erzeugung hörbaren Schalls
    durch Eigendemodulation amplitudenmodulierten\r\nLeistungsultraschalls (siehe
    u.a. Westervelt, Berktay) wird von zwei räumlich übereinander\r\nliegenden Wellen
    unterschiedlicher Frequenz im nichtlinearen Medium ausgegangen, so dass neben
    ihren\r\nHarmonischen auch Summen- und Differenzfrequenzen entstehen. Die perfekte
    räumliche Ueberdeckung\r\nder Wellen im Freifeld kann mit herkömmlichen Schallwandlern
    allerdings nur unzul¨anglich erreicht werden.\r\nTrotzdem sind in der Vergangenheit
    einige so genannte parametrische Lautsprecher entwickelt worden. Um\r\nannähernd
    die erwähnten Voraussetzungen zu gewährleisten, sind gängige Systeme mit einem
    Durchmesser\r\nvon ca. 30 cm relativ groß. Dies soll auch dem angestrebten Sekundärschalldruck
    Rechnung tragen, der linear\r\nmit der effektiv abstrahlenden Fl¨ache wächst.
    Zum Aufbau dieser großen Flächen werden teilweise viele\r\nkleine Ultraschallwandler
    zu einem Array zusammengesetzt. Der hohe Preis einzelner Wandler aber auch\r\ndie
    notwendige Sortierung beispielsweise bezüglich ihrer Mittenfrequenz macht den
    Aufbau solcher Systeme\r\naufwändig. Erst am vollständig aufgebauten Array werden
    schließlich Frequenzgang und Richtcharakteristik\r\ndes Sekundärschalls ermittelt.
    Im Sinne kürzerer Entwicklungszeiten und -kosten wäre es wünschenswert,\r\nbereits
    vor dem Aufbau des Arrays allein durch Untersuchung des einzelnen Ultraschallwandlers
    eine Prognose\r\nüber die zu erwartenden Eigenschaften des Gesamtsystems vornehmen
    zu können. In diesem Beitrag\r\nwird ein Versuchsaufbau vorgestellt, der unter
    strenger Beachtung der anfangs erwähnten Voraussetzungen\r\ndie parametrische
    Schallerzeugung mit nur einem Ultraschallwandler kleiner Baugröße erlaubt. Die
    Frequenzg\r\nänge des Sekundärschalls von Einzelelement und Array werden bei entsprechender
    Distanz gegen¨ubergestellt.\r\nVorzüge des neuen Messaufbaus, beispielsweise die
    Möglichkeit zur Variation von Druck, Temperatur\r\noder Luftfeuchtigkeit, um atmosphärische
    Einflüsse auf die parametrische Schallerzeugung zu untersuchen,\r\nwerden skizziert"

  text: 'One method to generate focused sound is to transmit amplitude modulated ultrasound
    of high energy in a nonlinear medium, so that sum and difference frequencies develop.
    Practically wide arrays of many small ultrasonic transducers are used, but the
    generation of very low frequencies is always weak. This contribution is about
    the experimental investigation of the {\textquotedbl}generation zone{\textquotedbl}
    -- that is the distance between the ultrasonic loudspeaker and the listener --
    and the decrease of the lower frequency bound of the audible sound beam with distance.
    The main focus is on the experimental setup, which permits the parametric sound
    generation with only one ultrasonic transducer and a waveguide. In addition, the
    new measurement setup enables to show an additional effect: The de-coherence of
    the primary ultrasound wave which may be caused by saturation of air. This is
    why the lower frequency bound decreases as well if we approach the ultrasonic
    transducer.'
