  text: In this paper we propose to employ directional statistics in a complex vector
    space to approach the problem of blind speech separation in the presence of spatially
    correlated noise. We interpret the values of the short time Fourier transform
    of the microphone signals to be draws from a mixture of complex Watson distributions,
    a probabilistic model which naturally accounts for spatial aliasing. The parameters
    of the density are related to the a priori source probabilities, the power of
    the sources and the transfer function ratios from sources to sensors. Estimation
    formulas are derived for these parameters by employing the Expectation Maximization
    (EM) algorithm. The E-step corresponds to the estimation of the source presence
    probabilities for each time-frequency bin, while the M-step leads to a maximum
    signal-to-noise ratio (MaxSNR) beamformer in the presence of uncertainty about
    the source activity. Experimental results are reported for an implementation in
    a generalized sidelobe canceller (GSC) like spatial beamforming configuration
    for 3 speech sources with significant coherent noise in reverberant environments,
    demonstrating the usefulness of the novel modeling framework.

  text: Today we can identify a big gap between requirement specification and the
    generation of test environments. This article extends the Classification Tree
    Method for Embedded Systems (CTM/ES) to fill this gap by new concepts for the
    precise specification of stimuli for operational ranges of continuous control
    systems. It introduces novel means for continuous acceptance criteria definition
    and for functional coverage definition.

  text: Many heterogeneous embedded systems, for example industrial automation and
    automotive applications, require hard-real time constraints to be exhaustively
    verified - which is a challenging task for the verification engineer. To cope
    with complexity, verification techniques working on different abstraction levels
    are best practice. SystemC is a versatile C++ based design and verification language,
    offering various mechanisms and constructs required for embedded systems modeling.
    Using the add-on SystemC Verification Library (SCV) elemental constrained-random
    stimuli techniques may be used for verification. However, SCV has several drawbacks
    such as lack of functional coverage. In this paper we present a functional coverage
    library that implements parts of the IEEE 1800-2005 SystemVerilog standard and
    allows capturing functional coverage throughout the design and verification process
    with SystemC. Moreover, we will demonstrate the usability of the approach with
    a case study working on a CAN bus model written in SystemC.

  text: In this paper we present a novel vehicle tracking algorithm, which is based
    on multi-level sensor fusion of GPS (global positioning system) with Inertial
    Measurement Unit sensor data. It is shown that the robustness of the system to
    temporary dropouts of the GPS signal, which may occur due to limited visibility
    of satellites in narrow street canyons or tunnels, is greatly improved by sensor
    fusion. We further demonstrate how the observation and state noise covariances
    of the employed Kalman filters can be estimated alongside the filtering by an
    application of the Expectation-Maximization algorithm. The proposed time-variant
    multi-level Kalman filter is shown to outperform an Interacting Multiple Model
    approach while at the same time being computationally less demanding.

  text: In this paper we present a novel vehicle tracking method which is based on
    multi-stage Kalman filtering of GPS and IMU sensor data. After individual Kalman
    filtering of GPS and IMU measurements the estimates of the orientation of the
    vehicle are combined in an optimal manner to improve the robustness towards drift
    errors. The tracking algorithm incorporates the estimation of time-variant covariance
    parameters by using an iterative block Expectation-Maximization algorithm to account
    for time-variant driving conditions and measurement quality. The proposed system
    is compared to an interacting multiple model approach (IMM) and achieves improved
    localization accuracy at lower computational complexity. Furthermore we show how
    the joint parameter estimation and localizaiton can be conducted with streaming
    input data to be able to track vehicles in a real driving environment.

  text: In automatic speech recognition, hidden Markov models (HMMs) are commonly
    used for speech decoding, while switching linear dynamic models (SLDMs) can be
    employed for a preceding model-based speech feature enhancement. In this paper,
    these model types are combined in order to obtain a novel iterative speech feature
    enhancement and recognition architecture. It is shown that speech feature enhancement
    with SLDMs can be improved by feeding back information from the HMM to the enhancement
    stage. Two different feedback structures are derived. In the first, the posteriors
    of the HMM states are used to control the model probabilities of the SLDMs, while
    in the second they are employed to directly influence the estimate of the speech
    feature distribution. Both approaches lead to improvements in recognition accuracy
    both on the AURORA2 and AURORA4 databases compared to non-iterative speech feature
    enhancement with SLDMs. It is also shown that a combination with uncertainty decoding
    further enhances performance.

  text: In this paper, parameter estimation of a state-space model of noise or noisy
    speech cepstra is investigated. A blockwise EM algorithm is derived for the estimation
    of the state and observation noise covariance from noise-only input data. It is
    supposed to be used during the offline training mode of a speech recognizer. Further
    a sequential online EM algorithm is developed to adapt the observation noise covariance
    on noisy speech cepstra at its input. The estimated parameters are then used in
    model-based speech feature enhancement for noise-robust automatic speech recognition.
    Experiments on the AURORA4 database lead to improved recognition results with
    a linear state model compared to the assumption of stationary noise.

  text: In developmental research, tutoring behavior has been identified as scaffolding
    infants' learning processes. It has been defined in terms of child-directed speech
    (Motherese), child-directed motion (Motionese), and contingency. In the field
    of developmental robotics, research often assumes that in human-robot interaction
    (HRI), robots are treated similar to infants, because their immature cognitive
    capabilities benefit from this behavior. However, according to our knowledge,
    it has barely been studied whether this is true and how exactly humans alter their
    behavior towards a robotic interaction partner. In this paper, we present results
    concerning the acceptance of a robotic agent in a social learning scenario obtained
    via comparison to adults and 8-11 months old infants in equal conditions. These
    results constitute an important empirical basis for making use of tutoring behavior
    in social robotics. In our study, we performed a detailed multimodal analysis
    of HRI in a tutoring situation using the example of a robot simulation equipped
    with a bottom-up saliency-based attention model. Our results reveal significant
    differences in hand movement velocity, motion pauses, range of motion, and eye
    gaze suggesting that for example adults decrease their hand movement velocity
    in an Adult-Child Interaction (ACI), opposed to an Adult-Adult Interaction (AAI)
    and this decrease is even higher in the Adult-Robot Interaction (ARI). We also
    found important differences between ACI and ARI in how the behavior is modified
    over time as the interaction unfolds. These findings indicate the necessity of
    integrating top-down feedback structures into a bottom-up system for robots to
    be fully accepted as interaction partners.

  text: A program for iterative fitting procedures to determine the NMR parameters
    from 51V solid-state MAS NMR spectra was developed. It contains options to use
    genetic algorithms and downhill-simplex optimizing procedures to extract the optimal
    parameter sets, which describe our spectra. As computational kernel the SIMPSON
    program is employed. Other kernels like SPINEVOLUTION are easily incorporable.
    The algorithms are checked for their suitability for the present optimization
    problem and optimal simulation conditions are determined, with the focus on minimal
    processing time. The procedure leads to a very good agreement between experimental
    and simulated spectra in a passable period of time. First results for spectra
    of model compounds for the active site of vanadium haloperoxidases are presented.

  text: The parameters describing the quadrupolar and CSA interactions of 51V solid-state
    MAS NMR investigations of model complexes mimicking vanadoenzymes as well as vanadium
    containing catalysts and enzyme complexes are interpreted with respect to the
    chemical structure. The interpretation is based on the data of 15 vanadium complexes
    including two new complexes with previously unpublished data and 13 complexes
    with data previously published by us. Correlations between the chemical structure
    and the 51V solid-state NMR data of this class of compounds have been established.
    Especially for the isotropic chemical shift Î´ iso and the chemical shift anisotropy
    Î´ Ïƒ , correlations with specific structural features like the coordination number
    of the vanadium atom, the number of coordinating nitrogens, the number of oxygen
    atoms and the chemical surrounding of the complex could be established for these
    compounds. Moreover, quantitative correlations between the solid-state NMR parameters
    and specific bond angles and bond lengths have been obtained. Our results can
    be of particular interest for future investigations concerning the structure and
    the mode of action of related vanadoenzymes and vanadate protein assemblies, including
    the use of vanadate adducts as transition state analogs for phosphate metabolizing
    systems.

  text: In this paper, we derive an uncertainty decoding rule for automatic speech
    recognition (ASR), which accounts for both corrupted observations and inter-frame
    correlation. The conditional independence assumption, prevalent in hidden Markov
    model-based ASR, is relaxed to obtain a clean speech posterior that is conditioned
    on the complete observed feature vector sequence. This is a more informative posterior
    than one conditioned only on the current observation. The novel decoding is used
    to obtain a transmission-error robust remote ASR system, where the speech capturing
    unit is connected to the decoder via an error-prone communication network. We
    show how the clean speech posterior can be computed for communication links being
    characterized by either bit errors or packet loss. Recognition results are presented
    for both distributed and network speech recognition, where in the latter case
    common voice-over-IP codecs are employed.

  text: In this paper a switching linear dynamical model (SLDM) approach for speech
    feature enhancement is improved by employing more accurate models for the dynamics
    of speech and noise. The model of the clean speech feature trajectory is improved
    by augmenting the state vector to capture information derived from the delta features.
    Further a hidden noise state variable is introduced to obtain a more elaborated
    model for the noise dynamics. Approximate Bayesian inference in the SLDM is carried
    out by a bank of extended Kalman filters, whose outputs are combined according
    to the a posteriori probability of the individual state models. Experimental results
    on the AURORA2 database show improved recognition accuracy.

  text: UML has been widely accepted by the software community for several years.
    As electronic systems design can no longer be seen as an isolated hardware design
    activity, UML becomes of significant interest as a unification language for systems
    description combining both HW and SW components. This article provides a comprehensive
    view of the UML applied to System-on-Chip (SoC) and hardware-related embedded
    systems design. The modeling concepts in the UML language are first introduced,
    including major diagrams for the representation of the behavior and the structure
    of systems. The principles behind application specific UML customizations (UML
    profiles) are summarized, and several examples relevant for SoC design are given,
    such as the SysML (System Modeling Language) and the SoC Profile. Thereafter,
    various approaches associating UML with existing HW/SW design languages are presented.
    Beyond language aspects, the article addresses the question of UML-based design
    flows, and shows how UML can be applied concretely to the development of electronic-based
    systems. The current situation about tool support constitutes the last focus of
    the article. In particular, we show how UML tools can be combined with well-known
    simulation environments, such as MATLAB.

  text: To provide user interfaces for a rich set of devices and interaction modalities,
    we follow a model-based development methodology. We devised an architecture which
    deploys user interfaces specified as dialogue models with abstract interaction
    objects and allows context-based adaptations by means of an external transcoding
    process. For the validation of the applicability of this methodology for developing
    usable multimodal multi-device systems, we present two case studies based on proof-of-concept
    implementations and assessed them with a large set of established design principles
    and different types of modality cooperation.

  text: Three cis-dioxovanadium(V) complexes with similar N -salicylidenehydrazide
    ligands modeling hydrogen bonding interactions of vanadate relevant for vanadium
    haloperoxidases are studied by 51V solid-state NMR spectroscopy. Their parameters
    describing the quadrupolar and chemical shift anisotropy interactions (quadrupolar
    coupling constant C Q , asymmetry of the quadrupolar tensor η Q , isotropic chemical
    shift δ iso , chemical shift anisotropy δ σ , asymmetry of the chemical shift
    tensor η σ and the Euler angles α , β and γ ) are determined both experimentally
    and theoretically using DFT methods. A comparative study of different methods
    to determine the NMR parameters by numerical simulation of the spectra is presented.
    Detailed theoretical investigations on the DFT level using various basis sets
    and structural models show that by useful choice of the methodology, the calculated
    parameters agree to the experimental ones in a very good manner.

  text: 'The Fehrer-Raab effect (simple reaction time is unaffected by metacontrast
    masking of the test stimulus) seems to imply that a stimulus can trigger a voluntary
    reaction without reaching a conscious representation. However, it is also possible
    that the mask triggers the reaction, and that the masked test stimulus causes
    a focussing of attention from which processing of the mask profits, thus reaching
    conscious representation earlier. This is predicted by the Weather Station Model
    of visual masking. Three experiments tested this explanation. Experiment 1 showed
    that the masked test stimulus caused a temporal shift of the mask. Experiment
    2 showed that the reaction in the Fehrer-Raab effect was not exclusively triggered
    by a conscious representation of the test stimulus: the mask was involved in evoking
    the reaction. Experiment 3 again revealed a temporal shift of the mask. However,
    the shift was only about half as large as the Fehrer-Raab effect. The psychometric
    functions suggested tha'

  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: This article describes our approach for the specification and verification
    of production automation systems with real-time properties. We focus on the graphical
    MFERT notation and RT-OCL (Real-Time Object Constraint Language) for the specification
    of state-oriented real-time properties. RT-OCL is an extension of the Object Constraint
    Language (OCL) that is part of the Unified Modeling Language (UML). We introduce
    the formal semantics of RT-OCL based on a formal model of UML Class and State
    Diagrams and provide a mapping to temporal logics. The applicability of our approach
    is demonstrated by the case study of a manufacturing system with automated guided
    vehicles.

  text: Variation in different mobile devices with different capabilities and interaction
    modalities as well as changing user context in nomadic applications, poses huge
    challenges to the design of user interfaces. To avoid multiple designs for each
    device or modality, it is almost a must to employ a model-based approach. In this
    short paper, we present a new dialog model for multimodal interaction together
    with an advanced control model, which can either be used for direct modeling by
    an interface designer or in conjunction with higher level models.
