text: 'An analysis of an optical Nyquist pulse synthesizer using Mach-Zehnder modulators
is presented. The analysis allows to predict the upper limit of the effective
number of bits of this type of photonic digital-to-analog converter. The analytical
solution has been verified by means of electro-optic simulations. With this analysis
the limiting factor for certain scenarios: relative intensity noise, distortions
by driving the Mach-Zehnder modulator, or the signal generator phase noise can
quickly be identified.'

text: Several methods, including order analysis, wavelet analysis and empirical
mode decomposition have been proposed and successfully employed for the health
state estimation of technical systems operating under varying conditions. However,
where information such as the speed of rotating machinery, component specifications
or other domain-specific information is unavailable, such methods are often infeasible.
Thus, this paper investigates the application of classical time-domain features,
features from the medical field and novel features from the highly comparative
time-series analysis (HCTSA) package, for the health state estimation of rotating
machinery operating under varying conditions. Furthermore, several feature selection
methods are investigated to identify features as viable health indicators for
the diagnostics and prognostics of technical systems. As a case study, the presented
methods are evaluated on real-world and experimentally acquired vibration data
of bearings operating under varying speed. The results show that the selected
features can successfully be employed as health indicators for technical systems
operating under varying conditions.

text: As an effective and accurate method for modelling composite materials, mean-field
homogenization is still not well studied in modelling non-linear and damage behaviours
of UD composites. Investigated micro FE-simulations show that the matrix of UD
composites exhibits different average plastic behaviour, named as average asymmetric
matrix plasticity (AAMP), when the composite behaves different under shear, longitudinal
and transverse loadings. In this study, a non-linear mean-field debonding model
(NMFDM) combining a mean-field model and a fibre–matrix interface debonding model,
is developed to simulate UD composites under consideration of AAMP, fibre–matrix
interface damage and progressive failure. AAMP is considered by using so-called
stress mode factor, which is expressed in terms of basic invariants of the matrix
deviatoric stress tensor and is used as an indicator for detection of differences
in the loading mode. The material behaviour of UD composites with imperfect interface
is assumed identical as for perfect interface and stiffness reduced fibres. Progressive
failure criteria are established with consideration of fibre breakage and matrix
crack for different fibre orientations. As a representative example for the NMFDM,
a C30/E201 UD composite is studied. To verify the model, experiments are conducted
on polymers, carbon fibres and UD CFRPs. Finally, the model is applied to simulate
a perforated CFRP laminate, which shows excellent prediction ability on deformation,
debonding and progressive failure.

text: In this publication, the near-field to far-field transformation using the
self-built near-field scanner NFS3000 is examined with regard to its geometry.
This device allows to measure electric and magnetic fields in small distances
to the DUT (Device under Test) with high geometric precision and high sensitivity.
Leading to a fast examination of EMC (Electromagnetic Compatibility) problems,
because the electromagnetic properties are better understandable and therefore
easier to solve than e.g. measurements in a far-field chamber. In addition, it
is possible to extrapolate the near-fields into the far-field and to determine
the radiation pattern of antennas and emitting objects. For this purpose, this
paper deals with the basis of this transformation, the so-called surface equivalence
theorem. This principle is then adapted to the measurement of near-field scanners
and implemented accordingly. Due to the non-ideal design of the near-field scanner,
the effects on a far-field transformation are finally presented and discussed.

text: Using near-field (NF) scan data to predict the far-field (FF) behaviour of
radiating electronic systems represents a novel method to accompany the whole
RF design process. This approach involves so-called Huygens' box as an efficient
radiation model inside an electromagnetic (EM) simulation tool and then transforms
the scanned NF measured data into the FF. For this, the basic idea of the Huygens'box
principle and the NF-to-FF transformation are briefly presented. The NF is measured
on the Huygens' box around a device under test using anNF scanner, recording the
magnitude and phase of the site-related magnetic and electric components. A comparison
between a fullwave simulation and the measurement results shows a good similarity
in both the NF and the simulated and transformed FF.Thus, this method is applicable
to predict the FF behaviour of any electronic system by measuring the NF. With
this knowledge, the RF design can be improved due to allowing a significant reduction
of EM compatibility failure at the end of the development flow. In addition, the
very efficient FF radiation model can be used for detailed investigations in various
environments and the impact of such an equivalent radiation source on other electronic
systems can be assessed.

text: "We present a peer-to-peer network that supports the efficient processing
of orthogonal range queries $R=\\bigtimes_{i=1}^{d}[a_i,\\,b_i]$ in a $d$-dimensional
point space.\\\\\r\nThe network is the same for each dimension, namely a distance
halving network like the one introduced by Naor and Wieder (ACM TALG'07).\r\nWe
show how to execute such range queries using $\\mathcal{O}\\left(2^{d'}d\\,\\log
m + d\\,|R|\\right)$ hops (and the same number of messages) in total. Here $[m]^d$
is the ground set, $|R|$ is the size and $d'$ the dimension of the queried range.\r\nFurthermore,
if the peers form a distributed network, the query can be answered in $\\mathcal{O}\\left(d\\,\\log
m + d\\,\\sum_{i=1}^{d}(b_i-a_i+1)\\right)$ communication rounds.\r\nOur algorithms
are based on a mapping of the Hilbert Curve through $[m]^d$ to the peers."

text: The transition from high school to university mathematics has proven to be
difficult for many students but especially for pre-service secondary teachers.
To support these students at mastering this transition, various universities have
introduced support measures of various kinds. The WiGeMath project developed a
taxonomy that makes it possible to describe and compare these measures concerning
their goals as well as their frame characteristics. We will exemplify the use
of the taxonomy in the description of one specific innovative measure that was
part of the WiGeMath evaluations. Moreover, we will present first results concerning
the goal-fulfilment of this measure concerning affective characteristics of the
student cohort and their predominant beliefs.

text: "Version Control Systems (VCS) are a valuable tool for software development\r\nand
document management. Both client/server and distributed (Peer-to-Peer)\r\nmodels
exist, with the latter (e.g., Git and Mercurial) becoming\r\nincreasingly popular.
Their distributed nature introduces complications,\r\nespecially concerning security:
it is hard to control the dissemination of\r\ncontents stored in distributed VCS
as they rely on replication of complete\r\nrepositories to any involved user.\r\n\r\nWe
overcome this issue by designing and implementing a concept for\r\ncryptography-enforced
access control which is transparent to the user. Use\r\nof field-tested schemes
(end-to-end encryption, digital signatures) allows\r\nfor strong security, while
adoption of convergent encryption and\r\ncontent-defined chunking retains storage
efficiency. The concept is\r\nseamlessly integrated into Mercurial---respecting
its distributed storage\r\nconcept---to ensure practical usability and compatibility
to existing\r\ndeployments."

text: In Switzerland, every student graduating from grammar school can begin to
study at a university. This leads to high dropout rates. Although students’ motivation
is considered a strong predictor of performance, the development of motivation
during students’ transition from high school to university has rarely been investigated.
Additionally, little is known about the relation of motivational aspects with
other influences on study performance. The present longitudinal study addresses
this research gap and examines the development of economics and management students’
study motivation. It encompasses four waves of data collected throughout the first
year, using quantitative online surveys. In total, the sample consists of 820
students. Data is analysed using latent change modelling. Results indicate that
students start at a higher level of intrinsic motivation compared to extrinsic
motivation. The variability of the starting value of the two constructs is also
differing. The analysis also shows a gradual decline in students’ motivation.
Above all, the transition from secondary to higher education seems to be a driver
for this decline.

text: Despite the rapid growth and potential of technology-based services, managers'
greatest challenges are gaining customer acceptance and increasing usage of these
new innovative services. In the B2C field, studies of self-service technology
show that perceived risk is an important factor influencing the use of service
technology. Though prior research explores different risk types that emerge in
consumer settings, risk perception in the B2B setting lacks a detailed examination
of different risk types influencing technology-based service adoption. Data from
49 qualitative interviews with providers and customers in two different B2B industries
inform this study. The findings emphasize the importance of functional and financial
risks in a B2B context and show that business customers' personal and psychological
fears hinder their use of technology-based services. Results highlight differences
in risk perception and evaluation between customers and providers.

text: "Academic success in Higher Education is influenced by a number of different
factors. This paper tackles the question if the individual levels of motivation,
anxiety, enjoyment and self-efficacy, measured immediately before entering university,
influence the probability of academic success. Former studies have shown an influence
of the high school grade, the learning environment and motivational variables.
They do not investigate, however, the individual levels of the mentioned constructs
before the beginning of the studies. This research was conducted at the University
of St. Gallen/Switzerland. The sample includes 695 first-year students who provided
information about the individual level of the mentioned constructs. \r\nDescriptive
statistics show that on average the students are highly motivated, have a high
level of self-efficacy and are looking forward to their studies before their beginning.
Yet, there are students who have a high level of fear of failure in the study
in spite of their high motivation and self-efficacy. A logistic regression shows
that there is a significant effect of fear of failure on the probability of study
success. This paper shows that fear of failure can increase the probability of
academic failure and thus become a self-fulfilling prophecy. It confirms fear
as an important factor for academic success. Furthermore, other important factors
for academic success, for example the high school grade, could be confirmed in
this study"

text: 'The parametric Bayesian Feature Enhancement (BFE) and a datadriven Denoising
Autoencoder (DA) both bring performance gains in severe single-channel speech
recognition conditions. The first can be adjusted to different conditions by an
appropriate parameter setting, while the latter needs to be trained on conditions
similar to the ones expected at decoding time, making it vulnerable to a mismatch
between training and test conditions. We use a DNN backend and study reverberant
ASR under three types of mismatch conditions: different room reverberation times,
different speaker to microphone distances and the difference between artificially
reverberated data and the recordings in a reverberant environment. We show that
for these mismatch conditions BFE can provide the targets for a DA. This unsupervised
adaptation provides a performance gain over the direct use of BFE and even enables
to compensate for the mismatch of real and simulated reverberant data.'

text: Coalition loyalty programs are on the rise, yet few studies investigate the
impact of service failures in such programs. Using data from a retail context,
the authors show that a program partner deemed responsible for a service failure
suffers negative customer responses. However, customers’ perceptions of the benefits
of the coalition loyalty program buffer these consequences. Perhaps most importantly,
when customers perceive the program's special treatment benefits as low, direct
and indirect spillover effects occur, such that a service failure by one program
partner has a negative effect on customer loyalty toward the program itself.

text: In order to increase mechanical strength, heat dissipation and ampacity and
to decrease failure through fatigue fracture, wedge copper wire bonding is being
introduced as a standard interconnection method for mass production. To achieve
the same process stability when using copper wire instead of aluminum wire a profound
understanding of the bonding process is needed. Due to the higher hardness of
copper compared to aluminum wire it is more difficult to approach the surfaces
of wire and substrate to a level where van der Waals forces are able to arise
between atoms. Also, enough friction energy referred to the total contact area
has to be generated to activate the surfaces. Therefore, a friction model is used
to simulate the joining process. This model calculates the resulting energy of
partial areas in the contact surface and provides information about the adhesion
process of each area. The focus here is on the arising of micro joints in the
contact area depending on the location in the contact and time. To validate the
model, different touchdown forces are used to vary the initial contact areas of
wire and substrate. Additionally, a piezoelectric tri-axial force sensor is built
up to identify the known phases of pre-deforming, cleaning, adhering and diffusing
for the real bonding process to map with the model. Test substrates as DBC and
copper plate are used to show the different formations of a wedge bond connection
due to hardness and reaction propensity. The experiments were done by using 500
$\mu$m copper wire and a standard V-groove tool.

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: This study shows how venture capital investors can identify potential biases
in multi-year management forecasts before an investment decision and derive significantly
more accurate failure predictions. By advancing a cross-sectional projection method
developed by prior research and using firm-specific information in financial statements
and business plans, we derive benchmarks for management revenue forecasts. With
these benchmarks, we estimate forecast errors as an a priori measure of biased
expectations. Using this measure for our proprietary dataset on venture-backed
start-ups in Germany, we find evidence of substantial upward forecast biases.
We uncover that firms with large forecast errors fail significantly more often
than do less biased entrepreneurs in years following the investment. Overall,
our results highlight the implications of excessive optimism and overconfidence
in entrepreneurial environments and emphasize the relevance of accounting information
and business plans for venture capital investment decisions.
