text: "The involvement of human workers is an essential part of the design of production
systems. In this\r\ncontext, test scenarios in Virtual Reality are increasingly
used to verify the fulfillment of requirements.\r\nThis paper proposes a procedure
for generating virtual test scenarios. The objective is to support human-\r\ncentered
design by means of virtual measurement systems. The procedure involves three steps:\r\nselecting
relevant human factors in requirements, modeling the virtual test scenario, and
carrying out\r\nthe verification study. The goal is to advance the significance
of testing outputs."

text: "The focus of this article are the results of the measurement of pedagogical
competencies of students of theology who have completed an internship in Germany.
The educational knowledge, competence self-assessments and their development as
well as the assessment of the goals achieved by students in the internship are
considered, taking into account the orientation of the teacher education course
towards a school type. In order to contextualize the results of the measurement
of educational knowledge and those of the survey of competence self-assessments
(N = 304), ideas are shown how the relationship between knowledge and ability
is constituted and findings on the type of school-specific professionalization
are summarized. Subsequently, hypotheses are derived, the design of the study,
the method and the test instruments are described, the results are presented and
discussed. Contrary to expectations, the results show that neither the educational
science knowledge, the competence self-assessments and their development nor the
assessment of the goals achieved in the internship by pros- pective teachers differ
depending on the type of school. The discussion relates to on the structure of
the teacher training courses, the mental figures for the development of skills
and the conception of the measuring instruments.\r\n"

text: Im Zentrum dieses Beitrags stehen Ergebnisse der Messung pädagogischer Kompetenzen
Studierender. Dabei werden sowohl das bildungswissenschaftliche Wissen als auch
die Entwicklung der Kompetenzselbsteinschätzungen in den Bereichen Unterrichten,
Erziehen, Beurteilen und Innovieren unter Berücksichtigung individueller Voraussetzungen
(Alter, Geschlecht, Abiturnote, Bachelornote, Konfession) betrachtet. Um die Ergebnisse
hinsichtlich ihrer Bedeutung für die Professionalisierung angehender Lehrkräfte
diskutieren zu können, wird, den empirischen Erkenntnissen voranstehend, die Bedeutung
von Wissen für berufliches Können herausgearbeitet. Daran anschließend werden
Hypothesen hergeleitet, die Anlage der Studie sowie die Testinstrumente vorgestellt,
die Ergebnisse präsentiert und diskutiert. Die Ergebnisse zeigen, dass die Abitur-
und Bachelornote die Varianz hinsichtlich des pädagogischen Wissens aufklären,
sich eine signifikante Entwicklung der Kompetenzselbsteinschätzungen angehender
Lehrkräfte feststellen lässt, aber sich angehende Religionslehrkräfte kaum von
anderen Studierenden unterscheiden. Die Diskussion nimmt u. a. Rückbezug auf die
Denkfiguren zur Entwicklung beruflichen Könnens und benennt Limitationen, die
mit der Studie und Kompetenzmessungen verbunden sind. Daran schließt die Formulierung
eines Ausblicks an. Der Beitrag zielt insbesondere darauf, repräsentative Ergebnisse
der Kompetenzmessung zu präsentieren und dabei potenzielle Einflussfaktoren auf
die studentische Kompetenzentwicklung zu beleuchten. Ein dadurch angereichertes
Konglomerat belastbarer Erkenntnisse zielt darauf, langfristig zur Ableitung lehrerbildungsdidaktischer
Überlegungen herangezogen werden zu können, die die studentische Professionalisierung
unterstützen.

text: 'This paper focuses on the results of the measurement of pedagogical competences
of students. In doing so, both the knowledge of the educational sciences and the development of competence self-assessments in the fields
of teaching, education, assessment andinnovating are taken into account. The study
makes use of the following individual requirements: age, sex, Abitur grade, Bachelor
grade, Confession. In order to be able to discuss the re-sults regarding their
importance for the professionalization of prospective teachers, the importance
of knowledge for professional skills is highlighted, preceded by empirical findings. Subsequently, hypotheses are derived, the plan of the study as well as the test instruments are presented, the results presented and discussed. The results show
that the Abitur and Bachelor grades clarify the variance in pedagogical knowledge,
that there is a significant development in the competence self-assessments of
prospective teachers, and that prospective religious teachers are not different
from other students. The discussion takes into account, among other things, the
ideas for the devel-opment of professional skills and identifies limitations associated
with the study. This is followed by the formula-tion of an outlook. The main aim
of the paper is to present representative results of the competence measurement
and to examine potential influencing factors on student competence development. A conglomerate of resilient knowledge
enriched by this aims to be used in the long term to derive teacher training didactic
considerations that support student professionalization.'

text: The construct of noticing is considered to be of crucial importance for professional
action of (prospective) physical education (PE) teachers in the context of (inclusive)
PE. In order to implement the demands of inclusive PE teaching, noticingwith regard
to processes of recognition proves to be particularly significant. Due to the
relevance of physicality, the design of recognition relationships that encourage
pupils' development results in specific requirements for the selective attention
and the theory-based interpretation of processes of recognition and disregard
in complex teaching situations. This facet of competence has hardly been studied
so far, partly due to the lack of instruments for standardised assessment of this
construct. In the context of this paper, the development and validation of a standardised,
video vignette-based test instrument for the measurement of noticingwith regard
to processes of recognition of prospective PE teachers is presented. The validation
focuses on the content of the test and the internal structure of the instrument
as well as on correlations with related constructs in terms of content. The results
from three consecutive validation studies provide indications of the reliability
and validity of the test score interpretation of the instrument ViProQiS_A. The
findings so far indicate that the standardised measurement of noticingwith regard
to processes of recognitionin inclusive PE could be realized on the basis of the
test instrument developed here.

text: This study deals with the damage behavior of metallic materials by the application
of different manufacturing processes and using different optical measurement methods
to identify the crack initiation in the damage specimen. The study is intended
to highlight the importance of considering manufacturing processes and optical
measurement methods in a numerical simulation when analyzing the damage behavior
of metallic materials. To describe the damage behavior of the material in the
process chain simulations, it is important to calibrate the parameters of damage
model more accurately. These parameters are determined using experimental investigation
of desired damage specimens. In this regard, a selected damage specimen manufactured
by different cutting processes is first experimentally and then numerically investigated.
It is shown that the manufacturing process and the optical measurement methods
influence the stress state analyzed in the numerical simulation.

text: "Access to precise meteorological data is crucial to be able to plan and install
renewable energy systems \r\nsuch as solar power plants and wind farms. In case
of solar energy, knowledge of local irradiance and air temperature \r\nvalues
is very important. For this, various methods can be used such as installing local
weather stations or using \r\nmeteorological data from different organizations
such as Meteonorm or official Deutscher Wetterdienst (DWD). An \r\nalternative
is to use satellite reanalysis datasets provided by organizations like the National
Aeronautics and Space \r\nAdministration (NASA) and European Centre for Medium-Range
Weather Forecasts (ECMWF). In this paper the \r\n“Modern-Era Retrospective analysis
for Research and Applications” dataset version 2 (MERRA-2) will be presented,
\r\nand its performance will be evaluated by comparing it to locally measured
datasets provided by Meteonorm and DWD. \r\nThe analysis shows very high correlation
between MERRA-2 and local measurements (correlation coefficients of 0.99) \r\nfor

of MERRA-2 data for \r\napplications requiring long historical data. Moreover,
availability of MERRA-2 for the whole world with an acceptable \r\nresolution
makes it a very valuable dataset."

text: "Several methods are available to answer questions regarding similarity and
accuracy,\r\neach of which has specific properties and limitations. This study
focuses on the\r\nLatent Congruence Model (LCM; Cheung, 2009), because of its
capacity to deal\r\nwith cross-informant measurement invariance issues. Until
now, no cross-national\r\napplications of LCM are present in the literature, perhaps
because of the difficulty\r\nto deal with both cross-national and cross-informant
measurement issues implied by\r\nthose models. This study presents a step-by-step
procedure to apply LCM to dyadic\r\ncross-national research designs controlling
for both cross-national and cross-informant\r\nmeasurement invariance. An illustrative
example on parent–child support exchanges in\r\nItaly and Germany is provided.
Findings help to show the different possible scenarios\r\nof partial invariance,
and a discussion related to how to deal with those scenarios is\r\nprovided. Future
perspectives in the study of parent–child similarity and accuracy in\r\ncross-national
research will be discussed."

text: One of the main objectives of production engineering is to reproducibly manufacture
(complex) defect-free parts. To achieve this, it is necessary to employ an appropriate
process or tool design. While this will generally prove successful, it cannot,
however, offset stochastic defects with local variations in material properties.
Closed-loop process control represents a promising approach for a solution in
this context. The state of the art involves using this approach to control geometric
parameters such as a length. So far, no research or applications have been conducted
with closed-loop control for microstructure and product properties. In the project
on which this paper is based, the local martensite content of parts is to be adjusted
in a highly precise and reproducible manner. The forming process employed is a
special, property-controlled flow-forming process. A model-based controller is
thus to generate corresponding correction values for the tool-path geometry and
tool-path velocity on the basis of online martensite content measurements. For
the controller model, it is planned to use a special process or microstructure
(correlation) model. The planned paper not only describes the experimental setup
but also presents results of initial experimental investigations for subsequent
use in the closed-loop control of α’-martensite content during flow-forming.

text: We build upon a recently proposed multi-objective view onto performance measurement
of single-objective stochastic solvers. The trade-off between the fraction of
failed runs and the mean runtime of successful runs – both to be minimized – is
directly analyzed based on a study on algorithm selection of inexact state-of-the-art
solvers for the famous Traveling Salesperson Problem (TSP). Moreover, we adopt
the hypervolume indicator (HV) commonly used in multi-objective optimization for
simultaneously assessing both conflicting objectives and investigate relations
to commonly used performance indicators, both theoretically and empirically. Next
to Penalized Average Runtime (PAR) and Penalized Quantile Runtime (PQR), the HV
measure is used as a core concept within the construction of per-instance algorithm
selection models offering interesting insights into complementary behavior of
inexact TSP solvers.

text: A multiobjective perspective onto common performance measures such as the
PAR10 score or the expected runtime of single-objective stochastic solvers is
presented by directly investigating the tradeoff between the fraction of failed
runs and the average runtime. Multi-objective indicators operating in the bi-objective
space allow for an overall performance comparison on a set of instances paving
the way for instance-based automated algorithm selection techniques.

text: An important task in quantum physics is the estimation of local quantities
for ground states of local Hamiltonians. Recently, Ambainis defined the complexity
class P^QMA[log], and motivated its study by showing that the physical task of
estimating the expectation value of a local observable against the ground state
of a local Hamiltonian is P^QMA[log]-complete. In this paper, we continue the
study of P^QMA[log], obtaining the following results. The P^QMA[log]-completeness
result of Ambainis requires O(log n)-local observ- ables and Hamiltonians. We
show that simulating even a single qubit measurement on ground states of 5-local
Hamiltonians is P^QMA[log]-complete, resolving an open question of Ambainis. We
formalize the complexity theoretic study of estimating two-point correlation functions
against ground states, and show that this task is similarly P^QMA[log]-complete.
P^QMA[log] is thought of as "slightly harder" than QMA. We justify this formally
by exploiting the hierarchical voting technique of Beigel, Hemachandra, and Wechsung
to show P^QMA[log] \subseteq PP. This improves the containment QMA \subseteq PP
from Kitaev and Watrous. A central theme of this work is the subtlety involved
in the study of oracle classes in which the oracle solves a promise problem. In
this vein, we identify a flaw in Ambainis' prior work regarding a P^UQMA[log]-hardness
proof for estimating spectral gaps of local Hamiltonians. By introducing a "query
validation" technique, we build on his prior work to obtain P^UQMA[log]-hardness
for estimating spectral gaps under polynomial-time Turing reductions.

text: A measurement method is presented that combines the advantages of the multisine
measurement technique with a prediction method for peak bending behavior. This
combination allows the analysis of the dynamic behavior of mechanical structures
at distinctly reduced measurement durations and has the advantage of reducing
high excitation impacts on the structure under test.

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: In this contribution we derive the Maximum A-Posteriori (MAP) estimates of
the parameters of a Gaussian Mixture Model (GMM) in the presence of noisy observations.
We assume the distortion to be white Gaussian noise of known mean and variance.
An approximate conjugate prior of the GMM parameters is derived allowing for a
computationally efficient implementation in a sequential estimation framework.
Simulations on artificially generated data demonstrate the superiority of the
proposed method compared to the Maximum Likelihood technique and to the ordinary
MAP approach, whose estimates are corrected by the known statistics of the distortion
in a straightforward manner.

text: In this paper, we consider the Maximum Likelihood (ML) estimation of the parameters
of a GAUSSIAN in the presence of censored, i.e., clipped data. We show that the
resulting Expectation Maximization (EM) algorithm delivers virtually biasfree
and efficient estimates, and we discuss its convergence properties. We also discuss
optimal classification in the presence of censored data. Censored data are frequently
encountered in wireless LAN positioning systems based on the fingerprinting method
employing signal strength measurements, due to the limited sensitivity of the
portable devices. Experiments both on simulated and real-world data demonstrate
the effectiveness of the proposed algorithms.

text: In this paper we present a robust location estimation algorithm especially
focused on the accuracy in vertical position. A loosely-coupled error state space
Kalman filter, which fuses sensor data of an Inertial Measurement Unit and the
output of a Global Positioning System device, is augmented by height information
from an altitude measurement unit. This unit consists of a barometric altimeter
whose output is fused with topographic map information by a Kalman filter to provide
robust information about the current vertical user position. These data replace
the less reliable vertical position information provided the GPS device. It is
shown that typical barometric errors like thermal divergences and fluctuations
in the pressure due to changing weather conditions can be compensated by the topographic
map information and the barometric error Kalman filter. The resulting height information
is shown not only to be more reliable than height information provided by GPS.
It also turns out that it leads to better attitude and thus better overall localization
estimation accuracy due to the coupling of spatial orientations via the Direct
Cosine Matrix. Results are presented both for artificially generated and field
test data, where the user is moving by car.

text: In this paper we present a novel vehicle tracking algorithm, which is based
on multi-level sensor fusion of GPS (global positioning system) with Inertial
Measurement Unit sensor data. It is shown that the robustness of the system to
temporary dropouts of the GPS signal, which may occur due to limited visibility
of satellites in narrow street canyons or tunnels, is greatly improved by sensor
fusion. We further demonstrate how the observation and state noise covariances
of the employed Kalman filters can be estimated alongside the filtering by an
application of the Expectation-Maximization algorithm. The proposed time-variant
multi-level Kalman filter is shown to outperform an Interacting Multiple Model
approach while at the same time being computationally less demanding.

text: In this paper we present a novel vehicle tracking method which is based on
multi-stage Kalman filtering of GPS and IMU sensor data. After individual Kalman
filtering of GPS and IMU measurements the estimates of the orientation of the
vehicle are combined in an optimal manner to improve the robustness towards drift
errors. The tracking algorithm incorporates the estimation of time-variant covariance
parameters by using an iterative block Expectation-Maximization algorithm to account
for time-variant driving conditions and measurement quality. The proposed system
is compared to an interacting multiple model approach (IMM) and achieves improved
localization accuracy at lower computational complexity. Furthermore we show how
the joint parameter estimation and localizaiton can be conducted with streaming
input data to be able to track vehicles in a real driving environment.

text: A combination of GPS (global positioning system) and INS (inertial navigation
system) is known to provide high precision and highly robust vehicle localization.
Notably during times when the GPS signal has a poor quality, e.g. due to the lack
of a sufficiently large number of visible satellites, the INS, which may consist
of a gyroscope and an odometer, will lead to improved positioning accuracy. In
this paper we show how velocity information obtained from GSM (global system for
mobile communications) signalling, rather than from a tachometer, can be used
together with a gyroscope sensor to support localization in the presence of temporarily
unavailable GPS data. We propose a sensor fusion system architecture and present
simulation results that show the effectiveness of this approach.

text: A simple pre-stress estimate method of Langevin transducers is studied. The
measurement setup consists of a capacitor, an impedance converter and a voltmeter.
Based on the piezoelectric equation and the basic circuit theory, the mathematical
expression between the pre-stress and the voltage across the capacitor is derived.
The pre-stress level can then be calculated out of the measurement of the capacitor
voltage. In order to evaluate the precision of this method, a force washer is
used to measure the pre-stress of the Langevin transducer. The result shows the
pre-stress level obtained from this method is 30-40\% higher than the pre-stress
level measured by the force washer. This method is simple and can be used to estimate
the pre-stress of various Langevin transducers. The precision of this method can
be raised if d33 is identified under different pre-stress levels.

text: 'In neurosurgery, delineation of tumor boundaries during resection of brain
tumors is of substantial relevance. During operation distinction between tumor
and healthy tissue rely on the abilities of the surgeon based on visual and tactile
differentiation. In this paper a high sensitivity actuator-sensor system using
a piezoelectric bimorph is presented. Frequency shift and transfer function of
the bimorphpsilas voltages are detected and evaluated. Sensorpsilas sensitivity
is evaluated using two frequency controls strategies: A phase-locked loop (PLL)
and a self-oscillating circuit. Results of measurements conducted on gel-phantoms
are presented and discussed.'
