  text: 'Recent studies highlight early childhood teachers’ mathematics-related competence.
    Developing this competence should be a main aspect of early childhood teachers’
    education. This is, however, not the case in all countries. Consequently, high-quality
    professional development courses are needed. Based on research results, we developed
    a competence-oriented continuous professional development course ("EmMa") and
    examined the effects of "EmMa" by asking: How does "EmMa" affect the development
    of early childhood teachers’ i) mathematical content knowledge, ii) mathematical
    pedagogical content knowledge and iii) beliefs towards mathematics in general?
    To answer these questions, we conducted a pre-test/post-test study including a
    control group with 99 in-service early childhood teachers. Results show that the
    course affected teachers’ mathematical pedagogical content knowledge and static
    orientation towards mathematics positively. From this we conclude that scaling-up
    "EmMa" might be a suitable approach to bridge the gap between pre-service education
    with nearly no mathematics and the challenges of early mathematics education.'

  text: In this paper, we experimentally evaluate algorithms for velocity estimation
    of a GSM 900 mobile terminal which are based on the analysis of the statistical
    properties of the fast fading process. It is shown how theses statistics can be
    obtained from the training sequences present in downlink transmission bursts without
    establishing an active connection. Realistic simulations of a GSM channel according
    to the COST 207 channel models have been conducted. These models incorporate effects
    like multipath propagation, fading, cochannel interference and additive noise.
    It is shown that velocity estimation by searching for the maximum slope of the
    power density spectrum of the fast fading performs best.

  text: In this paper, it is shown that a correlation criterion is the appropriate
    criterion for bottom-up clustering to obtain broad phonetic class regression trees
    for maximum likelihood linear regression (MLLR)-based speaker adaptation. The
    correlation structure among speech units is estimated on the speaker-independent
    training data. In adaptation experiments the tree outperformed a regression tree
    obtained from clustering according to closeness in acoustic space and achieved
    results comparable with those of a manually designed broad phonetic class tree

  text: We derive a class of computationally inexpensive linear dimension reduction
    criteria by introducing a weighted variant of the well-known K-class Fisher criterion
    associated with linear discriminant analysis (LDA). It can be seen that LDA weights
    contributions of individual class pairs according to the Euclidean distance of
    the respective class means. We generalize upon LDA by introducing a different
    weighting function
