text: Tire-wheel assembly is the only connection between road and vehicle. Contacting
directly with road within postcard size of contact area, it is mounted and guided
by the suspension system. Therefore kinematics and compliances of suspension system
greatly influence the frictional coupling of tire tread elements and road surface
asperities by affecting pressure and sliding velocity distribution in the contact
zone. This study emphasizes the development of a numerical methodology for frictional
rolling contact analysis with focus on interaction of suspension system dynamics
and tire-road contact using ADAMS. For this purpose a comprehensive flexible multibody
system of the multi-link rear suspension is established, where both flexible and
rigid bodies are modeled to allow large displacements with included elastic effects.
To meet accuracy requirements for the high frequency applications, such as road
excitations, the amplitude- and frequency-dependency of rubber-metal bushings
is included. Furthermore the proposed flexible viscoelastic suspension model is
enhanced by a Flexible Ring Tire Model (FTire), which describes a 3D tire dynamic
response and covers any road excitations by tread submodel connected to road surface
model. Concerning the verification and validation procedure numerous experiments
are carried out to confirm the validity and the accuracy of both the developed
submodels and the entire model. The devised approach makes it possible to investigate
the influence of suspension system design on dynamical rolling contact and to
evaluate tire tread wear. Therefore it can be a useful tool to predict frictional
power distribution within the contact area under more realistic conditions.

text: (K,Na)NbO3 ceramics have attracted much attention as lead-free piezoelectric
materials with high piezoelectric properties. High-quality (K,Na)NbO3 ceramics
can be sintered using KNbO3 and NaNbO3 powders synthesized by a hydrothermal method.
In this study, to enhance the quality factor of the ceramics, high-power ultrasonic
irradiation was employed during the hydrothermal method, which led to a reduction
in the particle size of the resultant powders.

text: 'In this contribution we present a theoretical and experimental investigation
into the effects of reverberation and noise on features in the logarithmic mel
power spectral domain, an intermediate stage in the computation of the mel frequency
cepstral coefficients, prevalent in automatic speech recognition (ASR). Gaining
insight into the complex interaction between clean speech, noise, and noisy reverberant
speech features is essential for any ASR system to be robust against noise and
reverberation present in distant microphone input signals. The findings are gathered
in a probabilistic formulation of an observation model which may be used in model-based
feature compensation schemes. The proposed observation model extends previous
models in three major directions: First, the contribution of additive background
noise to the observation error is explicitly taken into account. Second, an energy
compensation constant is introduced which ensures an unbiased estimate of the
reverberant speech features, and, third, a recursive variant of the observation
model is developed resulting in reduced computational complexity when used in
model-based feature compensation. The experimental section is used to evaluate
the accuracy of the model and to describe how its parameters can be determined
from test data.'

text: Power and bandwidth of piezoelectric harvesters can be increased by using
multiple piezoelectric elements in one harvester. In this contribution, a novel
energy harvesting cantilever array with magnetic tuning including three piezoelectric
bimorphs is investigated theoretically and experimentally, with a good agreement
between model and experiment. Other than harvester designs proposed before, this
array is easy to manufacture and insensitive to manufacturing tolerances because
its optimum operation frequency can be re-adjusted after fabrication. Using the
superposition principle, the Butterworth-Van Dyke model and a mechanical lumped
parameters model, the generated voltage and current are determined analytically.
Formulas for calculating the power generated by array harvesters with an arbitrary
number of piezoelectric elements connected in series or in parallel are derived.
It is shown that optimum harvester design must take both the connected load and
the operating frequency into account. Strategies for connecting multiple bimorphs
to increase the maximum generated power and/or enhance the bandwidth compared
to a single bimorph harvester are investigated. For bandwidth enhancement it is
essential that individual rectifiers are used for the bimorphs. An example with
three bimorphs shows that, depending on the chosen tuning strategy, the power
is increased by about 340\% or the bandwidth is increased by about 500\%, compared
to one single bimorph.

text: In this contribution we extend a previously proposed Bayesian approach for
the enhancement of reverberant logarithmic mel power spectral coefficients for
robust automatic speech recognition to the additional compensation of background
noise. A recently proposed observation model is employed whose time-variant observation
error statistics are obtained as a side product of the inference of the a posteriori
probability density function of the clean speech feature vectors. Further a reduction
of the computational effort and the memory requirements are achieved by using
a recursive formulation of the observation model. The performance of the proposed
algorithms is first experimentally studied on a connected digits recognition task
with artificially created noisy reverberant data. It is shown that the use of
the time-variant observation error model leads to a significant error rate reduction
at low signal-to-noise ratios compared to a time-invariant model. Further experiments
were conducted on a 5000 word task recorded in a reverberant and noisy environment.
A significant word error rate reduction was obtained demonstrating the effectiveness
of the approach on real-world data.

text: 'In the electronic system development, energy consumption is clearly becoming
one of the most important design concerns. From the system level point of view,
Dynamic Power Management (DPM) and Dynamic Voltage and Frequency Scaling (DVFS)
are two mostly applied techniques to adjust the tradeoff between the performance
and power dissipation at runtime. In this paper, we study the problem of combined
application of both techniques with regard to hard real-time systems running on
cluster-based multi-core processors. To optimize the processor energy consumption,
a heuristic based on simulated annealing with efficient termination criterion
is proposed. The experiment results show that the proposed algorithm outperforms
the existing approaches in terms of the energy reduction. '

text: AbstractNanoparticles (NP) have specific
catalytic properties, which are influenced by parameters like their size, shape,
or composition. Bimetallic NPs, composed of two metal elements can show an improved
catalytic activity compared to the monometallic NPs. We, herein, report on the
selective aerobic oxidation of benzyl alcohol catalyzed by unsupported Pd/Au and
Pd NPs at atmospheric pressure. NPs of varying compositions were synthesized and
characterized by UV/Vis spectroscopy, transmission electron microscopy (TEM),
and small-angle X-ray scattering (SAXS). The NPs were tested in the model reaction
regarding their catalytic activity, stability, and recyclability in batch and
continuous procedure. Additionally, in situ extended
X-ray absorption fine structure (EXAFS) measurements were performed in order to
get insight in the process during NP catalysis.

text: In this paper we present a novel noise power spectral density tracking algorithm
and its use in single-channel speech enhancement. It has the unique feature that
it is able to track the noise statistics even if speech is dominant in a given
time-frequency bin. As a consequence it can follow non-stationary noise superposed
by speech, even in the critical case of rising noise power. The algorithm requires
an initial estimate of the power spectrum of speech and is thus meant to be used
as a postprocessor to a first speech enhancement stage. An experimental comparison
with a state-of-the-art noise tracking algorithm demonstrates lower estimation
errors under low SNR conditions and smaller fluctuations of the estimated values,
resulting in improved speech quality as measured by PESQ scores.

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: The hydrothermal method enables the production of high-quality piezoelectric
materials. In this study, we propose to irradiate the reaction solutions with
ultrasonic power during the hydrothermal method to obtain a shorter reaction time
and a smooth film surface. A high-pressure reaction container for the ultrasonic
transducer was newly developed, and the ultrasonically-assisted hydrothermal method
was examined by using this container. The effect of ultrasonic assist on the synthesis
of lead-zirconate-titanate (PZT) thin films and (K,Na)NbO$_{3}$ powders was verified.
Thicker PZT film, thickness around 10 ${\mu}$m, could be obtained in one process,
and (K,Na)NbO$_{3}$ powder was synthesized in half the previous reaction time.

text: In this paper, we present a new technique for automatic speech recognition
(ASR) in reverberant environments. Our approach is aimed at the enhancement of
the logarithmic Mel power spectrum, which is computed at an intermediate stage
to obtain the widely used Mel frequency cepstral coefficients (MFCCs). Given the
reverberant logarithmic Mel power spectral coefficients (LMPSCs), a minimum mean
square error estimate of the clean LMPSCs is computed by carrying out Bayesian
inference. We employ switching linear dynamical models as an a priori model for
the dynamics of the clean LMPSCs. Further, we derive a stochastic observation
model which relates the clean to the reverberant LMPSCs through a simplified model
of the room impulse response (RIR). This model requires only two parameters, namely
RIR energy and reverberation time, which can be estimated from the captured microphone
signal. The performance of the proposed enhancement technique is studied on the
AURORA5 database and compared to that of constrained maximum-likelihood linear
regression (CMLLR). It is shown by experimental results that our approach significantly
outperforms CMLLR and that up to 80\% of the errors caused by the reverberation
are recovered. In addition to the fact that the approach is compatible with the
standard MFCC feature vectors, it leaves the ASR back-end unchanged. It is of
moderate computational complexity and suitable for real time applications.
