text: We study the quantum properties and statistics of photons emitted by a quantum-dot
biexciton inside a cavity. In the biexciton-exciton cascade, fine-structure splitting
between exciton levels degrades polarization-entanglement for the emitted pair
of photons. However, here we show that the polarization-entanglement can be preserved
in such a system through simultaneous emission of two degenerate photons into
cavity modes tuned to half the biexciton energy. Based on detailed theoretical
calculations for realistic quantum-dot and cavity parameters, we quantify the
degree of achievable entanglement.

text: Optical experiments on second-harmonic generation from split-ring-resonator
square arrays show a nonmonotonic dependence of the conversion efficiency on the
lattice constant. This finding is interpreted in terms of a competition between
dilution effects and linewidth or near-field changes due to interactions among
the individual elements in the array.

text: This dissertation explores learner beliefs about pronunciation and their interaction
with identity negotiations in a study-abroad context. Current research on studying
abroad has experienced a wave of interest in learner-centered questions, gradually
moving away from the narrow focus on students’ linguistic development. In particular,
the effects of study abroad on learner identities have attracted attention, revealing
the impact of the dispositions of individuals, as well as of interlocutors, on
the language learning process. The realm of speaking, especially with regard to
pronunciation research, however, has hardly benefited from this interest in the
individual perspectives of sojourners. Existing studies merely measure the extent
to which learners appropriate native-like accents, resulting in partly inconsistent
findings with limited insight into individual learning processes and factors.
I thus adopt a different focus by qualitatively investigating the interplay between
sojourners’ beliefs about pronunciation and their identity constructions and negotiations.
My research is based on five case studies of Canadian learners of German. Each
research subject has attended a German university for one or two semesters. In
applying narrative inquiry as a research tool for both the within- and cross-case
analyses, I investigate participants’ accounts in interviews and e-journals, as
conducted at different stages throughout the first sojourn term. Poststructuralist-constructivist
conceptualizations of learner identities and beliefs guide the data analysis and
interpretation. The results of the holistic and categorical content analyses give
insight into the intricate relationship between beliefs about pronunciation and
learners’ identity work. In their narratives, learners appear to actively use
pronunciation as a tool to construct identity facets in correspondence to specific
communities of practice, giving meaning to their investment in the sojourn experience.
This process of mediating between different identity constructions appears to
be highly complex and partially conflict-laden. The participants’ beliefs and
reported learning behaviours are interconnected with their definitions of learning
goals, which draw on native-speaker ideals to different extents and with varying
results. These orientations are in turn related to the subjects’ degrees of critical
language awareness, the latter a factor that appears to play a vital role in shaping
the ability of learners to take advantage of learning opportunities. In assessing
participants’ learning objectives and their readiness to reflect upon their beliefs
and orientations, my study also sheds light on the influence of different learning
factor constellations on intercultural learning. The results indicate that unidirectional
cause-and-effect relationships cannot be drawn between learners’ beliefs about
pronunciation and their abilities to approach their roles as intercultural speakers
in sojourn environments. My study rather underlines the importance of illuminating
individual learning experiences in their idiosyncrasies and complexities, which
may lead to a stronger consideration of learners’ subjective stances in both research
and teaching practice. The findings of my study suggest that the primary way that
language pedagogy can thus foster the ability to engage in intercultural encounters
is by helping learners to become aware of their subjective stances, their self-constructions,
and the influence of those on the learning process. Therefore, developing the
ability and willingness to critically reflect is crucial, especially with regard
to pronunciation. In illuminating the intricate nature of learner beliefs and
their influence on the learning process, my study demonstrates the importance
of qualitative, emic research into the acquisition of L2 pronunciation.

text: Within this paper, we will describe a new approach to customer interaction
management by integrating social networking channels into existing business processes.
Until now, contact center agents still read these messages and forward them to
the persons in charge of customer’s in the company. But with the introduction
of Web 2.0 and social networking clients are more likely to communicate with the
companies via Facebook and Twitter instead of filling data in contact forms or
sending e-mail requests. In order to maintain an active communication with international
clients via social media, the multilingual consumer contacts have to be categorized
and then automatically assigned to the corresponding business processes (e.g.
technicalservice, shipping, marketing, and accounting). This allows the company
to follow general trends in customer opinions on the Internet, but also record
two-sided communication for customer relationship management.

text: The paper proposes a modification of the standard maximum a posteriori (MAP)
method for the estimation of the parameters of a Gaussian process for cases where
the process is superposed by additive Gaussian observation errors of known variance.
Simulations on artificially generated data demonstrate the superiority of the
proposed method. While reducing to the ordinary MAP approach in the absence of
observation noise, the improvement becomes the more pronounced the larger the
variance of the observation noise. The method is further extended to track the
parameters in case of non-stationary Gaussian processes.

text: In this paper, we present a novel blocking matrix and fixed beamformer design
for a generalized sidelobe canceler for speech enhancement in a reverberant enclosure.
They are based on a new method for estimating the acoustical transfer function
ratios in the presence of stationary noise. The estimation method relies on solving
a generalized eigenvalue problem in each frequency bin. An adaptive eigenvector
tracking utilizing the power iteration method is employed and shown to achieve
a high convergence speed. Simulation results demonstrate that the proposed beamformer
leads to better noise and interference reduction and reduced speech distortions
compared to other blocking matrix designs from the literature.

text: In this work, a splitting and weighting scheme that allows for splitting a
Gaussian density into a Gaussian mixture density (GMM) is extended to allow the
mixture components to be arranged along arbitrary directions. The parameters of
the Gaussian mixture are chosen such that the GMM and the original Gaussian still
exhibit equal central moments up to an order of four. The resulting mixtures{\rq}
covariances will have eigenvalues that are smaller than those of the covariance
of the original distribution, which is a desirable property in the context of
non-linear state estimation, since the underlying assumptions of the extended
K ALMAN filter are better justified in this case. Application to speech feature
enhancement in the context of noise-robust automatic speech recognition reveals
the beneficial properties of the proposed approach in terms of a reduced word
error rate on the Aurora 2 recognition task.

text: In this paper we address the problem of initial seed selection for frequency
domain iterative blind speech separation (BSS) algorithms. The derivation of the
seeding algorithm is guided by the goal to select samples which are likely to
be caused by source activity and not by noise and at the same time originate from
different sources. The proposed algorithm has moderate computational complexity
and finds better seed values than alternative schemes, as is demonstrated by experiments
on the database of the SiSEC2010 challenge.
