text: In this paper we propose an approach to retrieve the absolute geometry of
an acoustic sensor network, consisting of spatially distributed microphone arrays,
from reverberant speech input. The calibration relies on direction of arrival
measurements of the individual arrays. The proposed calibration algorithm is derived
from a maximum-likelihood approach employing circular statistics. Since a sensor
node consists of a microphone array with known intra-array geometry, we are able
to obtain an absolute geometry estimate, including angles and distances. Simulation
results demonstrate the effectiveness of the approach.

text: This study examines the effect of audit on private firms’ cost of debt. We
use a sample of 1,949 small private firms operating in the period 2006-2010 with
optional financial statement audit. High quality data allows us to construct a
more precise interest rate measure than existing studies employ. After controlling
for obvious sources of demand for voluntary audits (ownership complexity, subsidiary
status, bank relations), we find a robust central result that voluntary audits
increase rather than decrease the cost of debt financing, contrary to several
existing studies. This finding indicates that voluntary audits are generally treated
as “adopting a label” and penalised by creditors, regardless of the perceived
auditor quality as a result of the lemon problem in the audit market. Even Big-4
audits increase the cost of debt, likely as a result due to the lemon problem
in the audit market, although the increase is smaller than for non-Big-4 audits.
The results are sensitive to the estimation method used (OLS, Heckman’s two-step,
PSM) and (sub-)sample selection. We show that disregarding the underlying assumptions
of these estimation methods may lead to incorrect inferences. Additional analyses
show that audited firms’ reported earnings are less informative about future operating
performance than earnings of their unaudited counterparts. Our results also indicate
that results are sensitive to cost of debt definition and this might have affected
the results reported in the existing literature.

text: The role of information and communication technology for economic growth has
been emphasized repeatedly. Technological breakthroughs have generated new forms
of services, such as self-services or remote services. Although these encounters
are qualitatively different from traditional service provision, prior service
management literature thus far had paid little attention to theory development
and the systematization of technology-based service encounters. To fill this research
gap, the present study outlines how new types of technology-based services fit
into existing service typologies and provides an extension of existing frameworks
to capture their unique characteristics. These insights in turn offer managerial
implications and highlight open research questions.

text: To optimize the ultrasound irradiation for cavitation based ultrasound applications
like sonochemistry or ultrasound cleaning, the correlation between cavitation
intensity and the resulting effect on the process is of interest. Furthermore,
changing conditions like temperature and pressure result in varying acoustic properties
of the liquid. That might necessitate an adaption of the ultrasound irradiation.
To detect such changes during operation, process monitoring is desired. Labor
intensive processes, that might be carried out for several hours, also require
process monitoring to increase their reliability by detection of changes or malfunctions
during operation. In some applications cavitation detection and monitoring can
be achieved by the application of sensors in the sound field. Though the application
of sensors is possible, this necessitates modifications on the system and the
sensor might disturb the sound field. In other applications harsh, process conditions
prohibit the application of sensors in the sound field. Therefore alternative
techniques for cavitation detection and monitoring are desired. The applicability
of an external microphone and a self-sensing ultrasound transducer for cavitation
detection were experimentally investigated. Both methods were found to be suitable
and easily applicable.

text: Self-optimizing mechatronic systems are a new class of technical systems.
On the one hand, new challenges regarding dependability arise from their additional
complexity and adaptivity. On the other hand, their abilities enable new concepts
and methods to improve the dependability of mechatronic systems. This paper introduces
a multi-level dependability concept for selfoptimizing mechatronic systems and
shows how probabilistic planning can be used to improve the availability and reliability
of systems in the operating phase. The general idea to improve the availability
of autonomous systems by applying probabilistic planning methods to avoid energy
shortages is exemplified on the example of an innovative railway vehicle.

text: In this paper we propose an approach to retrieve the geometry of an acoustic
sensor network consisting of spatially distributed microphone arrays from unconstrained
speech input. The calibration relies on Direction of Arrival (DoA) measurements
which do not require a clock synchronization among the sensor nodes. The calibration
problem is formulated as a cost function optimization task, which minimizes the
squared differences between measured and predicted observations and additionally
avoids the existence of minima that correspond to mirrored versions of the actual
sensor orientations. Further, outlier measurements caused by reverberation are
mitigated by a Random Sample Consensus (RANSAC) approach. The experimental results
show a mean positioning error of at most 25 cm even in highly reverberant environments.

text: In multiobjective optimization, set-based performance indicators are commonly
used to assess the quality of a Pareto front approximation. Based on the scalarization
obtained by these indicators, a performance comparison of multiobjective optimization
algorithms becomes possible. The R2 and the Hypervolume (HV) indicator represent
two recommended approaches which have shown a correlated behavior in recent empirical
studies. Whereas the HV indicator has been comprehensively analyzed in the last
years, almost no studies on the R2 indicator exist. In this paper, we thus perform
a comprehensive investigation of the properties of the R2 indicator in a theoretical
and empirical way. The influence of the number and distribution of the weight
vectors on the optimal distribution of μ solutions is analyzed. Based on a comparative
analysis, specific characteristics and differences of the R2 and HV indicator
are presented.

text: The steady supply of new optimization methods makes the algorithm selection
problem (ASP) an increasingly pressing and challenging task, specially for real-world
black-box optimization problems. The introduced approach considers the ASP as
a cost-sensitive classification task which is based on Exploratory Landscape Analysis.
Low-level features gathered by systematic sampling of the function on the feasible
set are used to predict a well-performing algorithm out of a given portfolio.
Example-specific label costs are defined by the expected runtime of each candidate
algorithm. We use one-sided support vector regression to solve this learning problem.
The approach is illustrated by means of the optimization problems and algorithms
of the BBOB’09/10 workshop.

text: Exploratory Landscape Analysis subsumes a number of techniques employed to
obtain knowledge about the properties of an unknown optimization problem, especially
insofar as these properties are important for the performance of optimization
algorithms. Where in a first attempt, one could rely on high-level features designed
by experts, we approach the problem from a different angle here, namely by using
relatively cheap low-level computer generated features. Interestingly, very few
features are needed to separate the BBOB problem groups and also for relating
a problem to high-level, expert designed features, paving the way for automatic
algorithm selection.

text: A large proportion of plastics today is compounded, which means the process
from refining a raw material to the processable material. For this process compounding
extruders are used which mostly involve tightly intermeshing, co-rotating twin
screw extruders. These extruders consist of two closely spaced screws which rotate
in the same direction and convey the raw material to the screw tip. These screws
are surrounded by several barrel modules which heat or cool the material. As the
whole design of the machine is modularly arranged the process behavior of a twin
screw extruder depends for the main part on the arrangement of the screw and the
barrel elements. Until today this arrangement and process optimization is conducted
by experienced engineers and with the help of trial-and-error methods. Furthermore,
theoretical models are used with which the behavior of the extruder is estimated.
As these models are mostly very complex they are only made available with the
realization in different software projects. One of the tools is called SIGMA.
Within this paper SIGMA is introduced as a software to optimize a twin screw extruder.
SIGMA supports the engineer already in the early stages of the extruder arrangement.

text: In double-sided markets for computing resources an optimal allocation schedule
among job offers and requests subject to relevant capacity constraints can be
determined. With increasing storage demands and emerging storage services the
question how to schedule storage jobs becomes more and more interesting. Since
such scheduling problems are often in the class NP-complete an exact computation
is not feasible in practice. On the other hand an approximation to the optimal
solution can easily be found by means of using heuristics. The problem with this
attempt is that the suggested solution may not be exactly optimal and is thus
less satisfying. Considering the two above mentioned solution approaches one can
clearly find a trade-off between the optimality of the solution and the efficiency
to get to a solution at all. This work proposes to apply and combine heuristics
in optimization to gain from both of their benefits while reducing the problematic
aspects. Following this method it is assumed to get closer to the optimal solution
in a shorter time compared to a full optimization.

text: An intentional positioning of optically active quantum dots using site-selective
growth by a combination of molecular beam epitaxy (MBE) and focused ion beam (FIB)
implantation in an all-ultra-high-vacuum (UHV) setup has been successfully demonstrated.
A square array of periodic holes on GaAs substrate was fabricated with FIB of
30 keV ions followed by an in situ annealing step. Subsequently, the patterned
holes were overgrown with an optimized amount of InAs in order to achieve site-selective
growth of the QDs on the patterned holes. Under well-optimized conditions, a selectivity
of single quantum dot growth in the patterned holes of 52% was achieved. Thereafter,
carrier injection and subsequent radiative recombination from the positioned InAs/GaAs
self-assembled QDs was investigated by embedding the QDs in the intrinsic part
of a GaAs-based p–i–n junction device. Electroluminescence spectra taken at 77
K show interband transitions up to the fifth excited state from the QDs.

text: Self-optimizing systems are able to adapt their behavior autonomously according
to their current self-determined objectives. Unforeseen influences could lead
to dependability-critical behavior of the system. Methods are required which secure
self-optimizing systems during operation. These methods to increase the dependability
of the system should already be taken into consideration in the design process.
This paper presents a guideline for the dependability-oriented design of self-optimizing
systems, which integrates established classical methods like failure mode and
effects analysis as well as methods based on self-optimization. On the one hand
self-optimization is used to increase the dependability of the system by integrating
objectives like safety, availability, and reliability to the objectives of the
system. On the other hand methods are required to ensure the self-optimization
itself. As basis for this guideline serves the principle solution of the system.
The six phases of the guideline extend the design process and lead to an enhanced
principle solution. Additionally, the guideline illustrates phases to implement
and validate the self-optimizing system. The proposed guideline is applied to
an innovative rail-bound vehicle, called RailCab, which is equipped with self-optimizing
function modules.

text: Recent advances in information processing enable new kinds of technical systems,
called self-optimizing systems. These systems are able to adapt their objectives
and their behavior according to the current situation and influences autonomously.
This behavior adaptation is non-deterministic and hence self-optimization is a
risk to the system, e.g. if the result of the self-optimization process does not
match the suddenly changed situation. In contrary, self-optimization could be
used to increase the dependability by pursuing objectives like reliability and
availability. In our preceding publications we introduced the so called multi-level
dependability concept to cope with this new kind of systems (cf. [6]). This concept
comprises the monitoring of the system behavior, the classification of the current
situation, and the selection of the appropriate measure, if reliability limits
are exceeded. In this paper we present for the first time experimental results.
The dependability concept is implemented in the self-optimizing active guidance
system of a railway vehicle. The test drives illustrate clearly that the proposed
concept is able to cope with, e.g., sensor failures, and is able to increase the
reliability and availability of the active guidance module.

text: Self-optimizing mechatronic systems are a new class of technical systems.
On the one hand, new challenges regarding dependability arise from their additional
complexity and adaptivity. On the other hand, their abilities enable new concepts
and methods to improve the dependability of mechatronic systems. This paper introduces
a multi-level dependability concept for self-optimizing mechatronic systems and
shows how planning can be used to improve the availability and reliability of
systems in the operating stages.

text: New mechatronic systems, called self-optimizing systems, are able to adapt
their behavior according to environmental, user and system specific influences.
Self-optimizing systems are complex and due to their non-deterministic behavior
comprise hidden risks, which cannot be foreseen in the design phase of the system.
Therefore, this paper presents modifications of the current condition monitoring
policy, to be able to cope with this new kind of systems. Beside avoiding critical
situations evoked by self-optimization, the proposed concept uses self-optimization
to increase the dependability of the system. In this case, the concept is applied
to the active guidance module of an innovative rail-bound vehicle.

text: Three cis-dioxovanadium(V) complexes with similar N -salicylidenehydrazide
ligands modeling hydrogen bonding interactions of vanadate relevant for vanadium
haloperoxidases are studied by 51V solid-state NMR spectroscopy. Their parameters
describing the quadrupolar and chemical shift anisotropy interactions (quadrupolar
coupling constant C Q , asymmetry of the quadrupolar tensor η Q , isotropic chemical
shift δ iso , chemical shift anisotropy δ σ , asymmetry of the chemical shift
tensor η σ and the Euler angles α , β and γ ) are determined both experimentally
and theoretically using DFT methods. A comparative study of different methods
to determine the NMR parameters by numerical simulation of the spectra is presented.
Detailed theoretical investigations on the DFT level using various basis sets
and structural models show that by useful choice of the methodology, the calculated
parameters agree to the experimental ones in a very good manner.
