text: Natural language software requirements descriptions enable end users to formulate
their wishes and expectations for a future software product without much prior
knowledge in requirements engineering. However, these descriptions are susceptible
to linguistic inaccuracies such as ambiguities and incompleteness that can harm
the development process. There is a number of software solutions that can detect
deficits in requirements descriptions and partially solve them, but they are often
hard to use and not suitable for end users. For this reason, we develop a software
system that helps end-users to create unambiguous and complete requirements descriptions
by combining existing expert tools and controlling them using automatic compensation
strategies. In order to recognize the necessity of individual compensation methods
in the descriptions, we have developed linguistic indicators, which we present
in this paper. Based on these indicators, the whole text analysis pipeline is
ad-hoc configured and thus adapted to the individual circumstances of a requirements
description.

text: 'Sociogenesis addresses a pervasive problem in psychology given by Cartesian
dualism that assigns the mental an inner locus apart from material activity. Aligning
ourselves to the ongoing critical discussions of interiorization in psychology,
we explore the crucial notion of space by highlighting language as sociocultural
and dialogical activity performed by other-oriented individuals. We discuss space
in terms of the “language spacetime”, a symbolic, embodied formation of mutually
positioned speaking and listening selves. This leads beyond the “inside-outside”
container metaphor and allows for a reformulation of interiorization. Interiorization
is conceptualized as a continuous series of different, though mutually related
movements between self and other and self and self that lead to and are supported
by specific formations in language activity: reversion, transposition, and decoupling.
Along a short passage of a video-based interview, we trace the reversion of dialogical
positions within the addressivity constellation of the two interlocutors, their
interactive creation of a heterotopic spacetime, and the decoupling of one speaker''s
psychological activity from the concrete here-and-now and the present other by
moving and acting into this new sphere. Interiorization appears as a movement
at the border of past, present, and possible future(s).'

text: Research on entrepreneurial learning highlights the importance of experience
and prior knowledge to entrepreneurial success. However, a conundrum remains and
we are still seeking answers as to why some novice entrepreneurs learn successfully
from their experiences and succeed, while some experienced entrepreneurs fail
with their ventures. In order to advance the discussion about the role of experience
during entrepreneurial learning, our critical reflection aims to (1) highlight
some of the shortcomings of experiential learning theory (ELT) and (2) illustrate
how alternative theoretical perspectives have the potential to advance our conceptual
understanding of entrepreneurial learning processes. We argue for an explanation
of entrepreneurial learning as a dynamic and self-regulated process that relies
on planning, monitoring, and self-reflection.

text: Reliability-adaptive systems allow an adaptation of system behavior based
on current system reliability. They can extend their lifetime at the cost of lowered
performance or vice versa. This can be used to adapt failure behavior according
to a maintenance plan, thus increasing availability while using up system capability
fully. To facilitate setup, a control algorithm independent of a degradation model
is desired. A closed loop control technique for reliability based on a health
index, a measure for system degradation, is introduced. It uses self-optimization
as means to implement behavior adaptation. This is based on selecting the priorities
of objectives that the system pursues. Possible working points are computed beforehand
using model-based multiobjective optimization techniques. The controller selects
the priorities of objectives and this way balances reliability and performance.
As exemplary application, an automatically actuated single plate dry clutch is
introduced. The entire reliability control is setup and lifetime experiments are
conducted. Results show that the variance of time to failure is reduced greatly,
making the failure behavior more predictable. At the same time, the desired usable
lifetime can be extended at the cost of system performance to allow for changed
maintenance intervals. Together, these possibilities allow for greater system
usage and better planning of maintenance.

text: In this work, the preparation of porous hybrid particle-based films by core-shell
particle design and convenient film preparation is reported. Monodisperse core
particles consisting of poly(methyl methacrylate‑co‑allyl methacrylate) (P(MMA‑co‑ALMA))
were synthesized by starved-feed emulsion polymerization followed by the introduction
of an initiator-containing monomer (inimer) for subsequent atom transfer radical
polymerization (ATRP). The inimer shell allowed for the introduction of allylhydrido
polycarbosilane (SMP-10) under ATRP conditions by grafting to the core particles.
The functionalization of the prepared core-shell particles was investigated by
IR spectroscopy (FTIR), scanning transmission electron microscopy (STEM) and solid-state
NMR combined with dynamic nuclear polarization (DNP). The obtained hard core/soft
preceramic shell particles were subjected to the melt-shear organization technique,
enabling a convenient alignment into a colloidal crystal structure in one single
step without the presence of a dispersion medium or solvent for the designed particles.
Moreover, the hybrid particle-based films were converted into a porous ceramic
structure upon thermal treatment. As a result, freestanding ceramic porous films
have been obtained after degradation of the organic template core particles. Noteworthy,
the conversion of the matrix material consisting of SMP-10 into the ceramic occurred
with preservation of the pristine colloidal crystal template structure. Herein,
the first example of core-shell particle preparation by combining different polymerization
methodologies and application of the convenient melt-shear organization technique
is shown, paving a new way to ceramic materials with tailored morphology and porosity.

text: Manufacturers increasingly integrate information and communication technologies
into their products so that they can provide IT-based services. Organizations
that formerly concentrated on transactional sales thus confront a new challenge
associated with managing service usage—retention and extracting value from investments
in smart technology. This study combines a marketing and an information systems
perspective in a field study conducted jointly with a large European car manufacturer.
Understanding the renewal decision for IT-based service contracts requires knowledge
from both disciplines. The paper shows that combining behavioral predictor variables
stemming from marketing research and technology-related perceptual variables stemming
from technology acceptance research increases the explanatory power and prediction
accuracy of forecasting models for customer renewal decisions. Specifically, the
authors show that perceptions of usefulness become more important the longer customers
use IT-based services and the more services they use within the service contract.

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: Websites increasingly embed semantic data for search engine optimization.
The most common ontology for semantic data, schema.org, is supported by all major
search engines and describes over 500 data types, including calendar events, recipes,
products, and TV shows. As of today, users wishing to pass this data to their
favorite applications, e.g., their calendars, cookbooks, price comparison applications
or even smart devices such as TV receivers, rely on cumbersome and error-prone
workarounds such as reentering the data or a series of copy and paste operations.
In this paper, we present Semantic Data Mediator (SDM), an approach that allows
the easy transfer of semantic data to a multitude of services, ranging from web
services to applications installed on different devices. SDM extracts semantic
data from the currently displayed web page on the client-side, offers suitable
services to the user, and by the press of a button, forwards this data to the
desired service while doing all the necessary data conversion and service interface
adaptation in between. To realize this, we built a reusable repository of service
descriptions, data converters, and service adapters, which can be extended by
the crowd. Our approach for linking services to websites relies solely on semantic
data and does not require any additional support by either website or service
developers. We have fully implemented our approach and present a real-world case
study demonstrating its feasibility and usefulness.

text: Time-variant age information of different parts of a system can be used for
system-level performance improvement through high-level task scheduling, thus
extending the life-time of the system. Progressive age information should provide
the age state that the system is in, and the rate that it is being aged at. In
this paper, we propose a structure that monitors certain paths of a circuit and
detects its gradual age growth, and provides the aging rate and aging state of
the circuit. The proposed monitors are placed on a selected set of nodes that
represent a timing bottleneck of the system. These monitors sample expected data
on these nodes, and compare them with the expected values. The timing of sampling
changes as the circuit ages and its delay increases. The timing of sampling will
provide a measure of aging advancement of a circuit. To assess the efficacy of
the proposed method and compare it with other state-of-the-art aging monitors,
we use them on selected nodes of the execution unit of different processors, as
well as some circuits from ITC99 benchmarks. The results reveal that the precision
of our proposed method is between 0.12 (ns) to 0.401 (ns). Its Area and power
overhead are negligible and are about 2.13 and 0.69 percent respectively.

text: The utilization and preparation of functional hybrid films for optical sensing
applications and membranes is of utmost importance. In this work, we report the
convenient and scalable preparation of self-crosslinking particle-based films
derived by directed self-assembly of alkoxysilane-based cross-linkers as part
of a core-shell particle architecture. The synthesis of well-designed monodisperse
core-shell particles by emulsion polymerization is the basic prerequisite for
subsequent particle processing via the melt-shear organization technique. In more
detail, the core particles consist of polystyrene (PS) or poly(methyl methacrylate)
(PMMA), while the comparably soft particle shell consists of poly(ethyl acrylate)
(PEA) and different alkoxysilane-based poly(methacrylate)s. For hybrid film formation
and convenient self-cross-linking, different alkyl groups at the siloxane moieties
were investigated in detail by solid-state Magic-Angle Spinning Nuclear Magnetic
Resonance (MAS, NMR) spectroscopy revealing different crosslinking capabilities,
which strongly influence the properties of the core or shell particle films with
respect to transparency and iridescent reflection colors. Furthermore, solid-state
NMR spectroscopy and investigation of the thermal properties by differential scanning
calorimetry (DSC) measurements allow for insights into the cross-linking capabilities
prior to and after synthesis, as well as after the thermally and pressure-induced
processing steps. Subsequently, free-standing and self-crosslinked particle-based
films featuring excellent particle order are obtained by application of the melt-shear
organization technique, as shown by microscopy (TEM, SEM).

text: Self-assembly of nanoparticles (NPs) forming unique structures has been investigated
extensively over the past few years. However, many self-assembled structures by
NPs are irreversible, because they are generally constructed using their suspensions.
It is still challenging for NPs to reversibly self-assemble in dry state, let
alone of polymeric NPs with general sizes of hundreds of nm. Herein, this study
reports a new reversible self-assembly phenomenon of NPs in dry state, forming
thermoreversible strip-like supermolecular structures. These novel NPs of around
150 nm are perfluorinated surface-undecenoated cellulose nanoparticles (FSU-CNPs)
with a core-coronas structure. The thermoreversible self-assembled structure is
formed after drying in the air at the interface between FSU-CNP films and Teflon
substrates. Remarkably, the formation and dissociation of this assembled structure
are accompanied by a reversible conversion of the surface hydrophobicity, film
transparency, and anisotropic properties. These findings show novel feasibility
of reversible self-assembly of NPs in dry state, and thereby expand our knowledge
of self-assembly phenomenon.

text: Usage of copper wire bonds allows to push power boundaries imposed by aluminum
wire bonds. Copper allows higher electrical, thermal and mechanical loads than
aluminum, which currently is the most commonly used material in heavy wire bonding.
This is the main driving factor for increased usage of copper in high power applications
such as wind turbines, locomotives or electric vehicles. At the same time, usage
of copper also increases tool wear and reduces the range of parameter values for
a stable process, making the process more challenging. To overcome these drawbacks,
parameter adaptation at runtime using self-optimization is desired. A self-optimizing
system is based on system objectives that evaluate and quantify system performance.
System parameters can be changed at runtime such that pre-selected objective values
are reached. For adaptation of bond process parameters, model-based self-optimization
is employed. Since it is based on a model of the system, the bond process was
modeled. In addition to static model parameters such as wire and substrate material
properties and vibration characteristics of transducer and tool, variable model
inputs are process parameters. Main simulation result is bonded area in the wiresubstrate
contact. This model is then used to find valid and optimal working points before
operation. The working point is composed of normal force and ultrasonic voltage
trajectories, which are usually determined experimentally. Instead, multiobjective
optimalization is used to compute trajectories that simultaneously optimize bond
quality, process duration, tool wear and probability of tool-substrate contacts.
The values of these objectives are computed using the process model. At runtime,
selection among pre-determined optimal working points is sufficient to prioritize
individual objectives. This way, the computationally expensive process of numerically
solving a multiobjective optimal control problem and the demanding high speed
bonding process are separated. To evaluate to what extent the pre-defined goals
of self-optimization are met, an offthe- shelf heavy wire bonding machine was
modified to allow for parameter adaptation and for transmitting of measurement
data at runtime. This data is received by an external computer system and evaluated
to select a new working point. Then, new process parameters are sent to the modified
bonding machine for use for subsequent bonds. With these components, a full self-optimizing
system has been implemented.

text: "Purpose\r\n– The purpose of this paper is to craft a future research agenda
to advance smart service research and practice. Smart services are delivered to
or via intelligent objects that feature awareness and connectivity. For service
researchers and managers, one of the most fascinating aspects of smart service
provision is that the connected object is able to sense its own condition and
its surroundings and thus allows for real-time data collection, continuous communication
and interactive feedback. \r\n\r\nDesign/methodology/approach\r\n– This article
is based on discussions in the workshop on “Fresh perspectives on technology in
service” at the International Network of Service Researchers on September 26,
2014 at CTF, Karlstad, Sweden. The paper summarizes the discussion on smart services,
adds an extensive literature review, provides examples from business practice
and develops a structured approach to new research avenues. \r\n\r\nFindings\r\n–
We propose that smart services vary on their individual level of autonomous decision-making,
visibility and embeddedness in objects and customer lives. Based on a discussion
of these characteristics, we identify research avenues regarding the perception
and nature of smart services, the adoption of smart services, the innovation through
smart services as well as regarding the development of new business models. \r\n\r\nOriginality/value\r\n–
Smart services is a new emerging topic in service marketing research, their implications
on organizations, customers and the service landscape have not been fully explored.
We provide a fresh perspective on service research by characterizing relevant
aspects of smart service that will stimulate fruitful future research and advance
the understanding and practice of smart services."

text: 'Advancements in information technology have changed the way customers experience
a service encounter and their relationship with service providers. Especially
technology-based self-service channels have found their way into the 21st century
service economy. While research embraces these channels for their cost-efficiency,
it has not examined whether a shift from personal to self-service affects customer–firm
relationships. Drawing from the service-dominant logic and its central concept
of value-in-context, we discuss customers’ value creation in self-service and
personal service channels and examine the long-term impact of these channels on
customer retention. Using longitudinal customer data, we investigate how the ratio
of self-service versus personal service use influences customer defection over
time. Our findings suggest that the ratio of self-service to personal service
used affects customer defection in a U-shaped manner, with intermediate levels
of both self-service and personal service use being associated with the lowest
likelihood of defection. We also find that this effect mitigates over time. We
conclude that firms should not shift customers toward self-service channels completely,
especially not at the beginning of a relationship. Our study underlines the importance
of understanding when and how self-service technologies create valuable customer
experiences and stresses the notion of actively managing customers’ cocreation
of value. '

text: A highly selective first study phase in many Swiss study programs leads to
a rather competitive climate among students. However, the atmosphere at the university
is an important factor for students' transition into Higher Education. An important
question in this context is whether students' are equipped with different dispositions
influencing how they cope with this transition. Other research has already shown
that different groups of students can be identified regarding their student behavior.
Yet, so far little is known about patterns of variables characterizing students,
transitioning successfully. The paper takes advantage of a person-centered approach,
i.e. the latent-class analysis, which makes it possible to identify groups of
individuals, sharing common attributes. The research was conducted as a longitudinal
study during their first year at a Swiss university. The return rate was about
67%, with 820 utilizable questionnaires at t1. Based on the analysis of students'
anxiety, intrinsic motivation and self-efficacy, three distinct classes of students
could be identified. The first class can be called the "highly motivated and self-confident"
students. The second class is characterized by the same pattern, however, on a
more intermediate level and the last class can be described as the "least motivated
and most anxious" group of students. This study contributes to research and theory
on students' transition into higher education and could be a first hint that students'
experiences of this transition can vary substantially.

text: Eine Vielzahl von Prozessen in der Chemie und Verfahrenstechnik kann durch
Ultraschall positiv beeinflusst werden. Oftmals ist ultraschallinduzierte Kavitation
der Hauptwirkmechanismus für die positiven Effekte der Beschallung. Daher ist
es notwendig die Kavitationsaktivität während des Prozesses zu quantifizieren
um die Beschallung für den jeweiligen Prozess optimal gestalten und überwachen
zu können. Eine Möglichkeit der prozessbegleitenden Kavitationsdetektion ist die
Auswertung der akustischen Emissionen von oszillierenden und kollabierenden Kavitationsblasen
mittels Drucksensoren in der Flüssigkeit. Raue Prozessrandbedingungen wie hohe
Temperaturen oder aggressive Flüssigkeiten erschweren es jedoch geeignete Sensoren
zu finden. Als Alternative wurde daher die Nutzbarkeit der Rückwirkung von Kavitationsereignissen
auf das elektrische Eingansgssignal des Ultraschallwandlers zur Quantifizierung
von Kavitation untersucht. Die experimentelle Analyse hat ergeben, dass das Einsetzen
und in einigen Fällen auch die Art der Kavitation auf Basis der Rückwirkung auf
das Stromsignal des Ultraschallwandlers bestimmt werden kann. Die Stärke der Kavitation
war hingegen nicht aus den Stromsignalen abzuleiten.

text: Intelligent mechatronic systems other the possibility to adapt system behavior
to current dependability. This can be used to assure reliability by controlling
system behavior to reach a pre-defined lifetime. By using such closed loop control,
the margin of error of useful lifetime of an individual system is lowered. It
is also possible to change the pre-defined lifetime during operation, by adapting
system behavior to derate component usage. When planning maintenance actions,
the remaining useful lifetime of each individual system has to be taken into account.
Usually, stochastic properties of a fleet of systems are analyzed to create maintenance
plans. Among these, the main factor is the probability of an individual system
to last until maintenance. If condition-based maintenance is used, this is updated
for each individual system using available information about its current state.
By lowering the margin of error of useful lifetime, which directly corresponds
to the time until maintenance, extended maintenance periods are made possible.
Also using reliability-adaptive operation, a reversal of degradation driven maintenance
planning is possible where a maintenance plan is setup not only according to system
properties, but mainly to requirements imposed by maintenance personnel or infrastructure.
Each system then adapts its behavior accordingly and fails according to the maintenance
plan, making better use of maintenance personnel and system capabilities at the
same time. In this contribution, the potential of maintenance plan driven system
behavior adaptation is shown. A model including adaptation process and maintenance
actions is simulated over full system lifetime to assess the advantages gained.

text: 'Haushaltsgeräte aus der Klasse der "Weißen Ware" tragen mit etwa einem Drittel
($34,2%$ \citeBDEW2013) zum privaten Energieverbrauch bei. Diese Veröffentlichung
präsentiert eine Struktur und die dafür notwendige optimale Betriebsstrategie
für Weiße Ware in einer Umgebung mit Strompreisen, die wegen der Volatilität der
Regenerativen Energien stark fluktuieren. Das vorgeschlagene Konzept nutzt dafür
ein dezentrales Energiemanagementsystem, das über drei Hierarchieebenen verteilt
ist: die Geräteebene, die Haushaltsebene und die Ortsnetzebene. Auf der Geräteebene
nutzt dieses Konzept zusätzlich Betriebsflexibilitäten der Haushaltsgeräte aus.'
