  text: In this paper, we propose an enhanced error concealment strategy at the server
    side of a distributed speech recognition (DSR) system, which is fully compatible
    with the existing DSR standard. It is based on a Bayesian approach, where the
    a posteriori probability density of the error-free feature vector is computed,
    given all received feature vectors which are possibly corrupted by transmission
    errors. Rather than computing a point estimate, such as the MMSE estimate, and
    plugging it into the Bayesian decision rule, we employ uncertainty decoding, which
    results in an integration over the uncertainty in the feature domain. In a typical
    scenario the communication between the thin client, often a mobile device, and
    the recognition server spreads across heterogeneous networks. Both bit errors
    on circuit-switched links and lost data packets on IP connections are mitigated
    by our approach in a unified manner. The experiments reveal improved robustness
    both for small- and large-vocabulary recognition tasks.

  text: The accuracy of distributed speech recognition has been shown to be very sensitive
    to errors occurring during transmission. One reason for this is that the classifier,
    usually trained under error free conditions, is unable to cope with the mismatch
    between an error free and error prone channel. In this paper we present a novel
    decision rule for classification which is able to account for channel errors.
    To achieve this, the classical Bayesian speech recognition approach has been reformulated
    for the server side, where the observation is known only to the extent, as is
    given by its a posteriori density function. We present a method to estimate the
    a posteriori density which is based on a Markov model of the source, which captures
    correlations of both static and dynamic features. A practical implementation is
    given, accompanied by experimental results for distributed speech recognition
    over an IP-network.

  text: In this paper we present the design of a particle filter for post filtering
    instantaneous positioning estimates of GSM mobile terminals. The instantaneous
    estimates are obtained by comparing signal power levels, which are reported by
    the mobile terminal to the base station, with a database of predictions using
    a novel statistically motivated similarity measure. Unlike a simple Euclidian
    distance measure, the proposed scheme incorporates inherent information about
    signal power level measurements requested by the serving base station but not
    reported by the mobile terminal. Furthermore, we show how the Monte Carlo method
    of particle filtering helps to obtain better position estimates and, surprisingly,
    also helps to reduce the computational complexity. Results are presented for real
    field data.

  text: A marginalized particle filter is proposed for performing single channel speech
    enhancement with a non-linear dynamic state model. The system consists of a particle
    filter for tracking line spectral pair (LSP) parameters and a Kalman filter per
    particle for speech enhancement. The state model for the LSPs has been learnt
    on clean speech training data. In our approach parameters and speech samples are
    processed at different time scales by assuming the parameters to be constant for
    small blocks of data. Further enhancement is obtained by an iteration which can
    be applied on these small blocks. The experiments show that similar SNR gains
    are obtained as with the Kalman-LM-iterative algorithm. However better values
    of the noise level and the log-spectral distance are achieved

  text: In spite of the outstanding importance of neuronavigational techniques the
    neurosurgeon has still highly to rely on his visual as well as tactile sense and
    his experience in distinguishing tumor tissue from intact brain parenchyma. All
    the more - as neuronavigation is based on preoperative imaging scans - considerable
    brain shift may occur during surgery and that will lead to erroneous results.
    Furthermore the surgeon loses his tactile sense during endoscopic surgery. Therefore
    control of tissue manipulation is limited today to the fiberoptic image techniques,
    possibly ensured by neuronavigational supervision or haptic feedback systems.
    In robotic guided surgery the missing tactile sensing will be particularly crucial.
    The human sense of touch is a highly complex sensory perception comprising epicritical
    and propiozeptive information processing. The development of a tool for intraoperative
    tactile perception will be a highly challenging task to improve the safety during
    surgery. Different sensor concepts (elasticity probe and resonant piezoelectric
    sensor) have been set up and adapted to distinguish elasticity differences in
    soft tissue mimicking gel phantoms. The elasticity probe is based on two leaf
    springs of different bending stiffness. The two tips of the beams act both on
    the material to be tested. The two deflections measured by strain gauges are processed
    in a mathematical model calculating the phantoms' stiffness. In contrast to this
    differential sensing concept the piezoelectric sensor, which is driven at its
    resonance, measures stiffness and damping of the phantoms by evaluating frequency
    or phase shift and amplitude change. Gelatine gels of different concentrations
    (5{\%}, 10{\%}, 20{\%} of gelatine) have been used for a characterization of sensor
    elements and their sensitivity to elasticity distinctions. Using the hand-guided
    elasticity probe the determination of gel elasticity is performed with high reliability.
    By constant mechanical load the piezoelectric sensor also presents a proportional
    dependency of tissue elasticity.

  text: "Die kontinuierliche und zuverlässige Konzentrationsmessung in Flüssigkeiten\r\nob
    zur Dosierung oder Prozessverfolgung stellt auch heute noch eine große\r\nmesstechnische
    Herausforderung dar. Akustische Sensorsysteme sind für diese\r\nMessaufgabe insbesondere
    unter industriellen Einsatzbedingungen prädestiniert.\r\nEs gibt eine Vielzahl
    verschiedener sorgfältig entworfener Ultraschallsensoren,\r\ndie diese Aufgabe
    durch Bestimmung der Schallgeschwindigkeit und\r\nder akustischen Impedanz lösen.
    Sie basieren meist auf senkrechten Durchgängen\r\ndes Schalls durch Grenzschichten,
    was sie sehr empfindlich gegenüber Ablagerungen\r\nmacht.\r\nDieser Beitrag liefert
    einen neuen Ansatz, indem die gesamte Oberfläche des\r\nMessraumes als akustischer
    Wellenleiter gestaltet und genutzt wird. Es hat sich\r\ngezeigt, dass sich durch
    Ausnutzen verschiedener Simulationswerkzeuge die\r\nHauptkomponenten eines Empfangssignals
    berechnen lassen, die eindeutig den\r\nverschiedenen modalen Anteilen zugeordnet
    werden können. Damit ist es möglich,\r\nallein aus dem Empfangssignal eines herkömmlichen
    Ultraschallwandlers\r\nauf die modalen Anteilsfaktoren zu schließen. Mit Hilfe
    dieser Koeffizienten\r\nund eines Modells des akustischen Wellenleiters lässt
    sich ein Gleichungssystem\r\naufstellen, das den Zusammenhang zwischen Dissipation
    in der Flüssigkeit\r\nsowie der durch Wellenleitergeometrie und Impedanzverhältnisse
    bedingten\r\nSignaldämpfung und den Amplituden der modalen Anteilsfaktoren beschreibt."

  text: In many different ultrasound applications mirrors are often used to deflect
    ultrasonic waves. The dimensions of the mirror and the applied materials have
    an essential influence on the output signal characteristics and the obtained measuring
    quantities. The extension of mirror geometry is not necessarily associated with
    a higher reflection coefficient. This can be explained with the aid of coincidence
    condition. A second criterion aims at the avoidance of the mirror resonance. This
    two conditions lead to an optimal dimensioning of mirror geometry with given material
    properties and operation mode, as exemplified for a rectangular mirror.

  text: Today's automotive headlights are built with transparent cover lenses. Therefore
    condensation of water leads to a visible optical defect. This paper presents a
    new approach for determination of the droplet size using colour phenomena in totally
    reflected light. It is based on a model of the generation of colour patterns by
    interference of several rays of light each multiple totally reflected inside condensed
    droplets. The droplet size may be determined by the colour if the contact angle
    is known. Measurement of both droplet size and colour all
