text: "Given n distinct points p1, p2, ... , pn in the plane, the map labeling\r\nproblem
with four squares is to place n axis-parallel equi-sized squares Q1, ... ,Qn\r\nof
maximum possible size such that pi is a corner of Qi and no two squares overlap.\r\nThis
problem is NP-hard and no algorithm with approximation ratio better\r\nthan 1/2
exists unless P = NP [10].\r\nIn this paper, we consider a scenario where we want
to visualize the information\r\ngathered by smart dust, i.e. by a large set of
simple devices, each consisting of\r\na sensor and a sender that can gather sensor
data and send it to a central station.\r\nOur task is to label (the positions
of) these sensors in a way described by the\r\nlabeling problem above. Since these
devices are not positioned accurately (for\r\nexample, they might be dropped from
an airplane), this gives rise to consider the\r\nmap labeling problem under the
assumption, that the positions of the points are\r\nnot fixed precisely, but perturbed
by random noise. In other words, we consider\r\nthe smoothed complexity of the
map labeling problem. We present an algorithm\r\nthat, under such an assumption
and Gaussian random noise with sufficiently large\r\nvariance, has linear smoothed
complexity."

text: We discuss nearest neighbor load balancing schemes on processor networks
which are represented by a cartesian product of graphs and present a new optimal
diffusion scheme for general graphs. In the first part of the paper, we introduce
the Alternating-Direction load balancing scheme, which reduces the number of load
balance iterations by a factor of 2 for cartesian products of graphs. The resulting
flow is theoretically analyzed and can be very high for certain cases. Therefore,
we further present the Mixed-Direction scheme which needs the same number of iterations
but computes in most cases a much smaller flow. In the second part of the paper,
we present a simple optimal diffusion scheme for general graphs, calculating a
balancing flow which is minimal in the l2 norm. It is based
on the spectra of the graph representing the network and needs only m-1 iterations
to balance the load with m being the number of distinct eigenvalues. Known optimal
diffusion schemes have the same performance, however the optimal scheme presented
in this paper can be implemented in a very simple manner. The number of iterations
of optimal diffusion schemes is independent of the load scenario and, thus, they
are practical for networks which represent graphs with known spectra. Finally,
our experiments exhibit that the new optimal scheme can successfully be combined
with the Alternating-Direction and Mixed-Direction schemes for efficient load
balancing on product graphs.

text: Satellite positioning systems, such as GPS or the future European system Galileo,
employ direct-sequence spread-spectrum signals. The positioning accuracy is strongly
affected by the quality of the pseudo range measurements. These measurements necessitate
code and carrier synchronization of the received signal with the internally generated
reference signals. In this type of systems one major error source is the multipath
phenomenon, which results in a sum of delayed and weighted copies of the original
signal to be present at the receiver input. This can result in a systematic error
of the code tracking loop resulting in range errors in the order of several tens
of meters. In this paper we propose an extension of the standard code tracking
loop capable of estimating the parameters of the line-of-sight (LOS) signal and
separating the LOS from the reflected signal portions. It is based on an analysis
of the cross correlation of the received signal with a locally generated code
sequence in the vicinity of the tracking point of a Delay-Locked Loop (DLL). For
this reason, we call this method Cross Correlation Function (CCF) Analysis. The
proposed method achieves considerably more accurate estimates than a DLL. Its
performance is comparable to the Multipath Estimating Delay-Locked Loop (MEDLL)
which is considered to be the best method for reducing multipath induced errors,
so far. However, the computational complexity of the CCF Analysis is by a factor
of three smaller compared to the MEDLL. Extensive simulations have been conducted
for the proposed method and the MEDLL in order to assess the robustness of the
two approaches under various signal constellations.

text: 'A major drawback of distributed versus terminal-based speech recognition
is the fact that transmission errors can lead to degraded recognition performance.
In this paper we employ soft features to mitigate the effect of bit errors on
wireless transmission links: At the receiver a posteriori probabilities of the
transmitted feature vectors are computed by combining bit reliability information
provided by the channel decoder and a priori knowledge about residual redundancy
in the feature vectors. While the first-order moment of the a posteriori probability
function is the MMSE estimate, the second-order moment is a measure of the uncertainty
in the reconstructed features. We conducted realistic simulations of GSM transmission
and achieved significant improvements in word accuracy compared to the error mitigation
strategy described in the ETSI standard.'

text: The paper is concerned with binaural signal processing for a bimodal human-robot
interface with hearing and vision. The two microphone signals are processed to
obtain an enhanced single-channel input signal for the subsequent speech recognizer
and to localize the acoustic source, an important information for establishing
a natural human-robot communication. We utilize a robust adaptive algorithm for
filter-and-sum beamforming (FSB) and extract speaker direction information from
the resulting FIR filter coefficients. Further, particle filtering is applied
which conducts a nonlinear Bayesian tracking of speaker movement. Good location
accuracy can be achieved even in highly reverberant environments. The results
obtained outperform the conventional generalized cross correlation (GCC) method.

text: While the main objective of adaptive Filter-and-Sum beamforming is to obtain
an enhanced speech signal for subsequent processing like speech recognition, we
show how speaker localization information can be derived from the filter coefficients.
To increase localization accuracy, speaker tracking is performed by non-linear
Bayesian state estimation, which is realized by sequential Monte Carlo methods.
Improved acquisition and tracking performance was achieved even in highly reverberant
environments, in comparison with both a Kalman Filter and a recently proposed
Particle Filter operating on the output of a nonadaptive Delay-and-Sum beamformer.

text: "In der industriellen Messtechnik werden optische, chemische und akustische
Messverfahren zur Ermittlung von Prozessgrößen eingesetzt. Dabei haben die akustischen
Messverfahren aufgrund ihrer Robustheit und Wartungsfreundlichkeit ein sehr großes
Einsatzgebiet. Impulsbasierte Ultraschallmesssysteme werden unter anderem zur
Messung von Durchfluss und Füllstand eingesetzt. Zunehmend werden sie aber auch
in der Flüssigkeitsanalytik zur Konzentrationsmessung und Stoffanalyse herangezogen.
Dabei führen Gasblasen in den zu untersuchenden flüssigen Medien immer wieder
zu Problemen, da bei Anwesenheit von Gasblasen die akustischen Stoffkenngrößen
verändert werden. Diese Probleme können ihre Ursache auch in der Signalverarbeitung
haben. Dieser Beitrag soll zeigen, welche Methoden zur Signalverarbeitung geeignet
sind um dieses Problem zu lösen.\r\n"

text: The classical forms of noise present in the frequency of MEMS resonators have
been recently investigated and described in detail. The present paper extends
this investigation to 1/f noise. That is of fundamental nature in microelectromechanical
systems (MEMS) resonators, and is given by the universal quantum 1/f effect. In
recent years new piezoelectric and compound semiconductor materials have been
developed along with advanced manufacturing technologies for MEMS including them.
These technologies enable the deposition of thin compound semiconductor, or PZT
films and their integration into MEMS devices.
