text: 'Users prefer natural language software requirements because of their usability
and accessibility. Many approaches exist to elaborate these requirements and to
support the users during the elicitation process. But there is a lack of adequate
resources, which are needed to train and evaluate approaches for requirement refinement.
We are trying to close this gap by using online available software descriptions
from SourceForge and app stores. Thus, we present two real-life requirements collections
based on online-available software descriptions. Our goal is to show the domain-specific
characteristics of content words describing functional requirements. On the one
hand, we created a semantic role-labeled requirements set, which we use for requirements
classification. On the other hand, we enriched software descriptions with linguistic
features and dependencies to provide evidence for the context-awareness of software
functionalities. '

text: Bridging the gap between informal, imprecise, and vague user requirements
descriptions and precise formalized specifications is the main task of requirements
engineering. Techniques such as interviews or story telling are used when requirements
engineers try to identify a user's needs. The requirements specification process
is typically done in a dialogue between users, domain experts, and requirements
engineers. In our research, we aim at automating the specification of requirements.
The idea is to distinguish between untrained users and trained users, and to exploit
domain knowledge learned from previous runs of our system. We let untrained users
provide unstructured natural language descriptions, while we allow trained users
to provide examples of behavioral descriptions. In both cases, our goal is to
synthesize formal requirements models similar to statecharts. From requirements
specification processes with trained users, behavioral ontologies are learned
which are later used to support the requirements specification process for untrained
users. Our research method is original in combining natural language processing
and search-based techniques for the synthesis of requirements specifications.
Our work is embedded in a larger project that aims at automating the whole software
development and deployment process in envisioned future software service markets.

text: Zuverlässigkeit, Sicherheit und Verfügbarkeit gewinnen bei der Anwendung von
technischen Systemen eine immer größere Bedeutung. Aus diesem Grund hat sich Condition
Monitoring, die Zustandsüberwachung eines technischen Produkts, in verschiedenen
Industriebranchen etabliert. Die sensorbasierte Überwachung eines Produkts während
seiner Betriebsdauer in Kombination mit Condition Monitoring Methoden ermöglichen
die Bestimmung des aktuellen Zustands des Produkts und somit eine Diagnose, ob
das Produkt seine ihm zugeschriebene Funktion zum aktuellen Zeitpunkt erfüllt.
Neben Diagnosen bietet Condition Monitoring auch die Möglichkeit Prognosen aufzustellen,
dabei wird die restliche Nutzungsdauer des Produkts aufbauend auf geeigneten Sensordaten
geschätzt. So kann eine intelligente Wartungsplanung umgesetzt werden, die im
Gegensatz zu klassischen Ansätzen keine festen Wartungsintervalle benötigt und
die Nachteile einer rein reaktiven Wartung kompensiert. Stattdessen ist es möglich
ein Element bis vor das Ende seiner Lebensdauer zu nutzen und erst dann zu warten,
um eine optimale Nutzung zu gewährleisten. Durch eine Bestimmung der verbleibenden
Restlebensdauer während des Betriebs ist eine optimale Wartungsplanung möglich,
wodurch die Verfügbarkeit und die Auslastung der überwachten Produkte signifikant
gesteigert werden kann. In dieser Arbeit soll ein produktspezifisches Condition
Monitoring System für Gummi-Metall-Elemente entwickelt werden. Diese Elemente
werden zur Federung, Geräusch- und/oder Schwingungsisolation in vielen verschiedenen
Anwendungen eingesetzt, wie bspw. in Nutz- und Schienenfahrzeugen oder Windenergieanlagen.
In Industrie und Forschung werden bereits Zustandsüberwachungen von Systemen mit
integrierten Gummi-Metall-Elementen eingesetzt, allerdings noch keine Condition
Monitoring Systeme zur alleinigen Zustandsüberwachung dieser Elemente. Aktuell
ist es üblich die Lebensdauer dieser Elemente aufbauend auf beschleunigten Lebensdauerversuchen
und Erfahrungswerten abzuschätzen. Mit dem Ziel die Lebensdauer des fokussierten
Produkts präziser vorherzusagen und damit eine intelligente Wartungsplanung zu
ermöglichen, wird die Entwicklung eines Condition Monitoring Systems für Gummi-Metall-Elemente
angestrebt und in dieser Arbeit erläutert.

text: The transportation of dry fine powders is an emerging technologic task, as
in biotechnology, pharmaceu-tical and coatings industry the particle sizes of
processed powders get smaller and smaller. Fine powdersare primarily defined by
the fact that adhesive and cohesive forces outweigh the weight forces, leadingto
mostly unwanted agglomeration (clumping) and adhesion to surfaces. Thereby it
gets more difficult touse conventional conveyor systems (e.g. pneumatic or vibratory
conveyors) for transport. A rather newmethod for transporting these fine powders
is based on ultrasonic vibrations, which are used to reducefriction between powder
and substrate. Within this contribution an experimental set-up consisting of apipe,
a solenoid actuator for axial vibration and an annular piezoelectric actuator
for the high frequencyradial vibration of the pipe is described. Since amplitudes
of the radial pipe vibration should be as large aspossible to get high effects
of friction reduction, the pipe is excited to vibrate in resonance. To determinethe
optimum excitation frequency and actuator position the vibration modes and resonance
frequenciesof the pipe are calculated and measured. Results are in good accordance.

text: In power electronics, copper connector pins are e.g. used to connect control
boards with power modules. The new chip generation based on SiC and GaN technology
increase the power density of semiconductor modules significantly with junction
temperatures reaching 200°C. To enable reliable operation at such high temperature,
the soldering of these connector pins should be substituted by a multi-dimensional
copper-copper bonding technology. A copper pin welded directly on DBC substrate
also simplifies the assembly. With this aim, a proper bond tool and a suitable
connector pin geometry are designed. This paper presents a two-dimensional trajectory
approach for ultrasonic bonding of copper pieces, e.g. connector pins, with the
intention to minimize mechanical stresses exposed to the substrate. This is achieved
using a multi-dimensional vibration system with multiple transducers known from
flip chip bonding. Applying a planar relative motion between the bonding piece
and the substrate increases the induced frictional power compared to one-dimensional
excitation. The core of this work is the development of a new tool design which
enables a reliable and effective transmission of the multidimensional vibration
into the contact area between nail-shaped bonding piece and substrate. For this
purpose, different bonding tool as well as bonding piece designs are discussed.
A proper bonding tool design is selected based on the simulated alternatives.
This tool is examined in bonding experiments and the results are presented. In
addition, different grades of hardness for bonding piece and substrate are examined
as well as different bonding parameters. Optical inspection of the bonded area
shows the emergence of initial micro welds in form of a ring which is growing
in direction of the interface boundaries with increasing bonding duration.

text: The integrated modeling of behavior and reliability in system development
delivers a model-based approach for reliability investigation by taking into account
the dynamic system behavior as well as the system architecture at different phases
of the development process. This approach features an automated synthesis of a
reliability model out of a behavior model enabling for the closed loop modeling
of degradation of the system and its (dynamic) behavior. The approach is integrated
into the development process following Systems Engineering. It is based on standard
models used in model-based development methodologies i.e. SysML or Matlab/Simulink.
In addition to the theoretical description of the necessary steps the procedure
is validated by an application example at two stages of the development process.

text: Piezoelectric inertia motors also known as stick-slip motors or (smooth) impact
drives use the inertia of a body to drive it in small steps by means of an uninterrupted
friction contact. In addition to the typical advantages of piezoelectric motors,
they are especially suited for miniaturisation due to their simple structure and
inherent fine-positioning capability. Originally developed for positioning in
microscopy in the 1980s, they have nowadays also found application in mass-produced
consumer goods. Recent research results are likely to enable more applications
of piezoelectric inertia motors in the future. This contribution gives a critical
overview of their historical development, functional principles, and related terminology.
The most relevant aspects regarding their design i.e., friction contact, solid
state actuator, and electrical excitation are discussed, including aspects of
control and simulation. The article closes with an outlook on possible future
developments and research perspectives.

text: State-of-the-art mechatronic systems offer inherent intelligence that enables
them to autonomously adapt their behavior to current environmental conditions
and to their own system state. This autonomous behavior adaptation is made possible
by software in combination with complex sensor and actuator systems and by sophisticated
information processing, all of which make these systems increasingly complex.
This increasing complexity makes the design process a challenging task and brings
new complex possibilities for operation and maintenance. However, with the risk
of increased system complexity also comes the chance to adapt system behavior
based on current reliability, which in turn increases reliability. The development
of such an adaption strategy requires appropriate methods to evaluate reliability
based on currently selected system behavior. A common approach to implement such
adaptivity is to base system behavior on different working points that are obtained
using multiobjective optimization. During operation, selection among these allows
a changed operating strategy. To allow for multiobjective optimization, an accurate
system model including system reliability is required. This model is repeatedly
evaluated by the optimization algorithm. At present, modeling of system reliability
and synchronization of the models of behavior and reliability is a laborious manual
task and thus very error-prone. Since system behavior is crucial for system reliability,
an integrated model is introduced that integrates system behavior and system reliability.
The proposed approach is used to formulate reliability-related objective functions
for a clutch test rig that are used to compute feasible working points using multiobjective
optimization.

text: Piezoelectric transducers are used in a wide range of applications. Reliability
of these transducers is an important aspect in their application. Prognostics,
which involve continuous monitoring of the health of technical systems and using
this information to estimate the current health state and consequently predict
the remaining useful lifetime (RUL), can be used to increase the reliability,
safety, and availability of the transducers. This is achieved by utilizing the
health state and RUL predictions to adaptively control the usage of the components
or to schedule appropriate maintenance without interrupting operation. In this
work, a prognostic approach utilizing self-sensing, where electric signals of
a piezoelectric transducer are used as the condition monitoring data, is proposed.
The approach involves training machine learning algorithms to model the degradation
of the transducers through a health index and the use of the learned model to
estimate the health index of similar transducers. The current health index is
then used to estimate RUL of test components. The feasibility of the approach
is demonstrated using piezoelectric bimorphs and the results show that the method
is accurate in predicting the health index and RUL.

text: Intelligente technische Systeme sind durch einen erhöhten Funktionsumfang
charakterisiert, der diese dazu befähigt, autonom auf wechselnde Umgebungsbedingungen,
Anforderungen und inhärente Systemzustände zu reagieren. Dies kann mit den Methoden
der Selbstoptimie-rung erreicht werden. Hier werden mit Verfahren der Mehrzieloptimierung
mögliche Betriebs-punkte des Systems bestimmt zwischen denen das System im Betrieb
autonom auswählt und somit eine Verhaltensadaption erwirkt. Zur Berechnung der
Betriebspunkte ist es notwendig ein Modell des Systemverhaltens aufzustellen und
das Verhalten hinsichtlich verschiedener, meist konfliktärer, Ziele zu quantifizieren.
Bei der Modellierung des Systemverhaltens und der Formulierung der Ziele stellt
die Absiche-rung der Verlässlichkeit auf Grund der zunehmenden Systemkomplexität
eine große Heraus-forderung dar, der im Entwicklungsprozess begegnet werden muss.
Die Implementierung von Selbstoptimierung bietet darüber hinaus in Kombination
mit einer Zustandsüberwachung im Betrieb die Möglichkeit einer zuverlässigkeitsbasierten
Verhaltensanpassung, deren Potential zu einer Steigerung der Verlässlichkeit genutzt
werden kann. In dieser Arbeit werden die Entwicklung intelligenter technischer
Systeme und die damit ver-bundenen notwendigen Entwicklungsschritte zur Absicherung
der Verlässlichkeit anhand von selbstoptimierenden Systemen betrachtet. Dazu gehören
die Formulierung verlässlichkeitsre-levanter Ziele und die Implementierung einer
Zustandsüberwachung als Basis für eine zuver-lässigkeitsbasierte Verhaltensanpassung.
Es werden auf Grundlage einer Beschreibung der Entwicklungsschritte, Potentiale
zur Steigerung der Verlässlichkeit sowie Chancen und zukünf-tige Herausforderungen
herausgestellt und diskutiert.

text: 'We explore how competition between physicians affects medical service provision.
Previous research has shown that, without competition, physicians deviate from
patient‐optimal treatment under payment systems like capitation and fee‐for‐service.
Although competition might reduce these distortions, physicians usually interact
with each other repeatedly over time and only a fraction of patients switches
providers at all. Both patterns might prevent competition to work in the desired
direction. To analyze the behavioral effects of competition, we develop a theoretical
benchmark that is then tested in a controlled laboratory experiment. Experimental
conditions vary physician payment and patient characteristics. Real patients benefit
from provision decisions made in the experiment. Our results reveal that, in line
with the theoretical prediction, introducing competition can reduce overprovision
and underprovision, respectively. The observed effects depend on patient characteristics
and the payment system, though. Tacit collusion is observed and particularly pronounced
with fee‐for‐service payment, but it appears to be less frequent than in related
experimental research on price competition. '

text: An end user generally writes down software requirements in ambiguous expressions
using natural language; hence, a software developer attuned to programming language
finds it difficult to understand th meaning of the requirements. To solve this
problem we define semantic categories for disambiguation and classify/annotate
the requirement into the categories by using machine-learning models. We extensively
use a language frame closely related to such categories for designing features
to overcome the problem of insufficient training data compare to the large number
of classes. Our proposed model obtained a micro-average F1-score of 0.75, outperforming
the previous model, REaCT.

text: Additive Manufacturing (AM) is a game changing production technology for aerospace
applications. Fused deposition modeling is one of the most widely used AM technologies
and recently has gained much attention in the advancement of many products. This
paper introduces an extensive review of fused deposition modeling and its application
in the development of high performance unmanned aerial vehicles. The process methodology,
materials, post processing, and properties of its products are discussed in details.
Successful examples of using this technology for making functional, lightweight,
and high endurance unmanned aerial vehicles are also highlighted. In addition,
major opportunities, limitations, and outlook of fused deposition modeling are
also explored. The paper shows that the emerge of fused deposition modeling as
a robust technique for unmanned aerial vehicles represents a good opportunity
to produce compact, strong, lightweight structures, and functional parts with
embedded electronic.

text: 'Micro Physiological Systems (MPS), also known as Multi-Organ-Chip, Organ-on-a-Chip,
or Body-on-a-Chip, are advanced microfluidic systems that allow the cultivation
of different types of cells and tissue in just one common circuit. Furthermore,
they thus can also adjust the interaction of these different tissues. Perspectival
MPS will replace animal testing. For fast and flexible manufacturing and marking
of MPS, a concept for a universal micromachining platform has been developed which
provides the following latest key technologies: laser micro cutting of polymer
foils, laser micro- and sub-micro-structuring of polymer foils, 3D printing of
polymer components as well as optical inspection and online process control. The
combination of different laser sources, processing optics, inspection systems,
and print heads on multiple axes allows the change and exactly positioning to
the workpiece during the process. Therewith, the realization of MPS including
3D printed components as well as direct laser interference patterned surfaces
for well-defined cell adhesion and product protection is possible. Additional
basic technologies for the generation of periodical line-like structures at polycarbonate
foils using special Direct Laser Interference Patterning (DLIP) optics as well
as for the 3D printing of fluid-tight cell culture reservoirs made of Acrylonitrile
Butadiene Styrene directly onto polycarbonate microfluidics were established.
A first prototype of the universal micromachining platform combining different
lasers with Direct Laser Writing and DLIP is shown. With this laser micro cutting
as well as laser micro-structuring of polycarbonate (PC) foils and therewith functionalization
for MPS application could be successfully demonstrated.'

text: The mechanical characterization of fused deposition modeling (FDM) parts is
mostly done by static tests. In many applications, parts are also dynamically
loaded. Here, fatigue tests can help to identify the expected lifetime of a part.
This article discusses the fatigue behavior of FDM specimens manufactured with
Ultem 9085. For this, tensile bars are manufactured according to ASTM D638 in
different build orientations. Tests are performed in a range of pulsating tensile
stresses, and S-N curves are documented for different build orientations. For
higher loads, the FDM anisotropy characterizes the lifetime of used specimens,
which is similar to static tensile bars. For lower loads, including a higher number
of cycles to failure, S-N curves of different build orientations converge. In
further tests, tensile bars were chemically smoothed with chloroform vapor. Chemical
smoothing reduces surface roughness and increases tensile strength of specimens
in the upright build direction. Fatigue tests of chemically treated specimens
show no significant lifetime increase.

text: Fused Deposition Modeling (FDM) is an Additive Manufacturing (AM) technology
which is used for prototypes, single-part-production and also small batch productions.
For use as a final product, it is important that the parts have good mechanical
properties, a high dimensional accuracy and smooth surfaces. The knowledge of
the mechanical properties is very important for the design engineer when it comes
to the component design. In this paper, investigations were conducted with the
polymer ABS-M30 from Stratasys Inc. To achieve a quality improvement of FDM parts,
various toolpath parameters and orientations were used. Within the mechanical
properties, the tensile, flexural and impact strength were evaluated. Furthermore,
the tensile strength of FDM parts is compared to injection molded specimens. With
optimized parameters, an increase of the tensile strength by up to 28 % and a
doubling of the impact strength were possible.
