text: Self-piercing riveting is an established technique for joining multi-material
structures in car body manufacturing. Rivets for self-piercing riveting differ
in their geometry, the material used, the condition of the material and their
surface condition. To shorten the manufacturing process by omitting the heat treatment
and the coating process, the authors have elaborated a concept for the use of
stainless steel with high strain hardening as a rivet material. The focus of the
present investigation is on the evaluation of the influences of the rivet’s geometry
and material on its deformation behaviour. Conventional rivets of types P and
HD2, a rivet with an improved geometry made of treatable steel 38B2, and rivets
made of the stainless steels 1.3815 and 1.4541 are examined. The analysis is conducted
by means of multi-step joining tests for two material combinations comprising
high-strength steel HCT70X and aluminium EN AW-5083. The joints are cut to provide
a cross-section and the deformation behaviour of the different rivets is analysed
on the basis of the measured changes in geometry and hardness. In parallel, an
examination of the force-stroke curves provides further insights. It can be demonstrated
that, besides the geometry, the material strength, in particular, has a significant
influence on the deformation behaviour of the rivet. The strength of steel 1.4541
is seen to be too low for the joining task, while the strength of steel 1.3815
is sufficient, and hence the investigation confirms the capability of rivets made
of 1.3815 for joining even challenging material combinations.

text: "Finding a good query plan is key to the optimization of query runtime. This
holds in particular for cost-based federation\r\nengines, which make use of cardinality
estimations to achieve this goal. A number of studies compare SPARQL federation
engines across different performance metrics, including query runtime, result
set completeness and correctness, number of sources selected and number of requests
sent. Albeit informative, these metrics are generic and unable to quantify and
evaluate the accuracy of the cardinality estimators of cost-based federation engines.
To thoroughly evaluate cost-based federation engines, the effect of estimated
cardinality errors on the overall query runtime performance must be measured.
In this paper, we address this challenge by presenting novel evaluation metrics
targeted at a fine-grained benchmarking of cost-based federated SPARQL query engines.
We evaluate five cost-based federated SPARQL query engines using existing as well
as novel evaluation metrics by using LargeRDFBench queries. Our results provide
a detailed analysis of the experimental outcomes that reveal novel insights, useful
for the development of future cost-based federated SPARQL query processing engines."

text: Mobile shopping apps have been using Augmented Reality (AR) in the last years
to place their products in the environment of the customer. While this is possible
with atomic 3D objects, there is is still a lack in the runtime configuration of
3D object compositions based on user needs and environmental constraints. For
this, we previously developed an approach for model-based AR-assisted product
configuration based on the concept of Dynamic Software Product Lines. In this demonstration
paper, we present the corresponding tool support ProConAR in the form of a Product
Modeler and a Product Configurator. While the Product Modeler is an Angular web
app that splits products (e.g. table) up into atomic parts (e.g. tabletop, table
legs, funnier) and saves it within a configuration model, the Product Configurator
is an Android client that uses the configuration model to place different product
configurations within the environment of the customer. We show technical details
of our ready to use tool-chain ProConAR by describing its implementation and usage
as well as pointing out future research directions.

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: 'To build successful products, the developers have to adapt their product
features and business models to uncertain customer needs. This adaptation is part
of the research discipline of Hypotheses Engineering (HE) where customer needs
can be seen as hypotheses that need to be tested iteratively by conducting experiments
together with the customer. So far, modeling support and associated traceability
of this iterative process are missing. Both, in turn, are important to document
the adaptation to the customer needs and identify experiments that provide most
evidence to the customer needs. To target this issue, we introduce a model-based
HE approach with a twofold contribution: First, we develop a modeling language
that models hypotheses and experiments as interrelated hierarchies together with
a mapping between them. While the hypotheses are labeled with a score level of
their current evidence, the experiments are labeled with a score level of maximum
evidence that can be achieved during conduction. Second, we provide an iterative
process to determine experiments that offer the most evidence improvement to the
modeled hypotheses. We illustrate the usefulness of the approach with an example
of testing the business model of a mobile application.'

text: The scientific impact of research papers is multi-dimensional and can be determined
quantitatively by means of citation analysis and qualitatively by means of content
analysis. Accounting for the widely acknowledged limitations of pure citation
analysis, we adopt a knowledge-based perspective on scientific impact to develop
a methodology for content-based citation analysis which allows determining how
papers have enabled knowledge development in subsequent research (knowledge impact).
As knowledge development differs between research genres, we develop a new knowledgebased
citation analysis methodology for the genre of standalone literature reviews (LRs).
We apply the suggested methodology to the IS business value domain by manually
coding 22 LRs and 1,228 citing papers (CPs) and show that the results challenge
the assumption that citations indicate knowledge impact. We derive implications
for distinguishing knowledge impact from citation impact in the LR genre. Finally,
we develop recommendations for authors of LRs, scientific evaluation committees
and editorial boards of journals how to apply and benefit from the suggested methodology,
and we discuss its efficiency and automatization.

text: Understanding a new literature corpus can be a grueling experience for junior
scholars. Nevertheless, corresponding guidelines have not been updated for decades.
We contend that the traditional strategy of skimming all papers and reading selected
papers afterwards needs to be revised. Therefore, we design a new strategy that
guides the overall exploratory process by prioritizing influential papers for
initial reading, followed by skimming the remaining papers. Consistent with schemata
theory, starting with in-depth reading allows readers to acquire more substantial
prior content schemata, which are representa-tive for the literature corpus and
useful in the following skimming process. To this end, we develop a prototype
that identifies the influential papers from a set of PDFs, which is illustrated
in a case study in the IT business value domain. With the new strategy, we envision
a more efficient process of exploring unknown literature corpora.

text: This paper deals with aspect phrase extraction and classification in sentiment
analysis. We summarize current approaches and datasets from the domain of aspect-based
sentiment analysis. This domain detects sentiments expressed for individual aspects
in unstructured text data. So far, mainly commercial user reviews for products
or services such as restaurants were investigated. We here present our dataset
consisting of German physician reviews, a sensitive and linguistically complex
field. Furthermore, we describe the annotation process of a dataset for supervised
learning with neural networks. Moreover, we introduce our model for extracting
and classifying aspect phrases in one step, which obtains an F1-score of 80%.
By applying it to a more complex domain, our approach and results outperform previous
approaches.

text: To decide in which part of town to open stores, high street retailers
consult statistical data on customers and cities, but they cannot analyze their
customers’ shopping behavior and geospatial features of a city due to missing
data. While previous research has proposed recommendation systems and
decision aids that address this type of decision problem – including factory
location and assortment planning – there currently is no design knowledge
available to prescribe the design of city center area recommendation systems
(CCARS). We set out to design a software prototype considering local
customers’ shopping interests and geospatial data on their shopping trips for
retail site selection. With real data on 500 customers and 1,100 shopping trips,
we demonstrate and evaluate our IT artifact. Our results illustrate how retailers
and public town center managers can use CCARS for spatial location selection,
growing retailers’ profits and a city center’s attractiveness for its citizens.

text: Much work on innovation strategy assumes or theorizes that competition
in innovation elicits duplication of research and that disclosure decreases such
duplication. We validate this empirically using the American Inventors Protection
Act (AIPA), three complementary identification strategies, and a new measure of
blocked future patent applications. We show that AIPA—intended to reduce duplication,
through default disclosure of patent applications 18 months after filing—reduced
duplication in the U.S. and European patent systems. The blocking measure provides
a clear and micro measure of technological competition that can be aggregated
to facilitate the empirical investigation of innovation, firm strategy, and the
positive and negative externalities of patenting. This paper
was accepted by Joshua Gans, business strategy.

text: "Literature reviews (LRs) play an important role in the development of domain
knowledge in all fields. Yet, we observe a\r\nlack of insights into the activities
with which LRs actually develop knowledge. To address this important gap, we (1)\r\nderive
knowledge building activities from the extant literature on LRs, (2) suggest a
knowledge-based typology of LRs\r\nthat complements existing typologies, and (3)
apply the suggested typology in an empirical study that explores how LRs\r\nwith
different goals and methodologies have contributed to knowledge development. The
analysis of 240 LRs published\r\nin 40 renowned IS journals between 2000 and 2014
allows us to draw a detailed picture of knowledge development\r\nachieved by one
of the most important genres in the IS field. An overarching contribution of our
work is to unify extant\r\nconceptualizations of LRs by clarifying and illustrating
how LRs apply different methodologies in a range of knowledge\r\nbuilding activities
to achieve their goals with respect to theory."

text: "The aim of this study was to find out whether teaching how to search for
literature\r\nwould be more beneficial to students and teachers if done online
through short videos\r\nrather than in person during course time. To find out
whether online videos are more\r\nbeneficial, two courses were asked to fill in
questionnaires, one at the beginning and\r\none at the end of the semester. One
of the courses received the input online via videos\r\nand were given an exercise
to put the newly learned skills to use, the other course\r\nserved as a control
group and learned how to search for literature during the course.\r\nThe results
show that while the difference between the two groups is not significant,\r\nthe
videos can still be regarded as being more beneficial than teaching the necessary\r\nskills
during course time."

text: 'The proportion of freshmen enrolled in dual study programmes has steadily
increased in recent years. From the perspective of potential students, these programmes
are highly attractive because they combine types of learning that used to be largely
separate at an institutional level: vocational and academic learning. In training-integrated
dual study programmes, different institutional contexts, governance regimes, teaching
styles and learning environments make bridging these two worlds of learning a
challenge for both educators and learners. However, these programmes also allow
leeway for didactic innovation, through the cooperation of different types of
educational institutions and through new ways of using available didactic methods,
and for establishing a new relationship between higher education (HE) and vocational
education and training (VET). This paper positions training-integrated dual study
programmes as an object of design-based research (DBR). By developing and using
an extended model for the pedagogic development of HEIs, “pädagogische Hochschulentwicklung”
(Brahm, Jenert, & Euler, 2016a, p. 19; Euler, 2013, p. 360), the paper systematically
identifies generic educational problems in these hybrids. Based on a literature
review, this paper classifies and explains the design challenges at the level
of the learning environment, the study programme and the organisation. The challenges
revolve mainly around the cooperation and integration of HE and VET. The paper
concludes with an outlook on future DBR projects designing dual studies.'

text: Sequential model-based optimization (SMBO) approaches are algorithms for solving
problems that require computationally or otherwise expensive function evaluations.
The key design principle of SMBO is a substitution of the true objective function
by a surrogate, which is used to propose the point(s) to be evaluated next. SMBO
algorithms are intrinsically modular, leaving the user with many important design
choices. Significant research efforts go into understanding which settings perform
best for which type of problems. Most works, however, focus on the choice of the
model, the acquisition function, and the strategy used to optimize the latter.
The choice of the initial sampling strategy, however, receives much less attention.
Not surprisingly, quite diverging recommendations can be found in the literature.
We analyze in this work how the size and the distribution of the initial sample
influences the overall quality of the efficient global optimization (EGO) algorithm,
a well-known SMBO approach. While, overall, small initial budgets using Halton
sampling seem preferable, we also observe that the performance landscape is rather
unstructured. We furthermore identify several situations in which EGO performs
unfavorably against random sampling. Both observations indicate that an adaptive
SMBO design could be beneficial, making SMBO an interesting test-bed for automated
algorithm design.

text: 'In this work we focus on the well-known Euclidean Traveling Salesperson Problem
(TSP) and two highly competitive inexact heuristic TSP solvers, EAX and LKH, in
the context of per-instance algorithm selection (AS). We evolve instances with
nodes where the solvers show strongly different performance profiles. These instances
serve as a basis for an exploratory study on the identification of well-discriminating
problem characteristics (features). Our results in a nutshell: we show that even
though (1) promising features exist, (2) these are in line with previous results
from the literature, and (3) models trained with these features are more accurate
than models adopting sophisticated feature selection methods, the advantage is
not close to the virtual best solver in terms of penalized average runtime and
so is the performance gain over the single best solver. However, we show that
a feature-free deep neural network based approach solely based on visual representation
of the instances already matches classical AS model results and thus shows huge
potential for future studies.'

text: "Digital data on tangible and intangible cultural assets is an essential part
of daily life, communication and experience. It has a lasting influence on the
perception of cultural identity as well as on the interactions between research,
the cultural economy and society. Throughout the last three decades, many cultural
heritage institutions have contributed a wealth of digital representations of
cultural assets (2D digital reproductions of paintings, sheet music, 3D digital
models of sculptures, monuments, rooms, buildings), audio-visual data (music,
film, stage performances), and procedural research data such as encoding and annotation
formats. The long-term preservation and FAIR availability of research data from
the cultural heritage domain is fundamentally important, not only for future academic
success in the humanities but also for the cultural identity of individuals and
society as a whole. Up to now, no coordinated effort for professional research
data management on a national level exists in Germany. NFDI4Culture aims to fill
this gap and create a user-centered, research-driven infrastructure that will
cover a broad range of research domains from musicology, art history and architecture
to performance, theatre, film, and media studies.\r\n The
research landscape addressed by the consortium is characterized by strong institutional
differentiation. Research units in the consortium's community of interest comprise
university institutes, art colleges, academies, galleries, libraries, archives
and museums. This diverse landscape is also characterized by an abundance of research
objects, methodologies and a great potential for data-driven research. In a unique
effort carried out by the applicant and co-applicants of this proposal and ten
academic societies, this community is interconnected for the first time through
a federated approach that is ideally suited to the needs of the participating
researchers. To promote collaboration within the NFDI, to share knowledge and
technology and to provide extensive support for its users have been the guiding
principles of the consortium from the beginning and will be at the heart of all
workflows and decision-making processes. Thanks to these principles, NFDI4Culture
has gathered strong support ranging from individual researchers to high-level
cultural heritage organizations such as the UNESCO, the International Council
of Museums, the Open Knowledge Foundation and Wikimedia. On this basis, NFDI4Culture
will take innovative measures that promote a cultural change towards a more reflective
and sustainable handling of research data and at the same time boost qualification
and professionalization in data-driven research in the domain of cultural heritage.
This will create a long-lasting impact on science, cultural economy and society
as a whole."

text: The aim to reduce pollutant emission has led to a trend towards lightweight
construction in car body development during the last years. As a consequence of
the resulting need for multi-material design, mechanical joining technologies
become increasingly important. Mechanical joining allows for the combination of
dissimilar materials, while thermic joining techniques reach their limits. Self-piercing
riveting enables the joining of dissimilar materials by using semi-tubular rivets
as mechanical fasteners. The rivet production, however, is costly and time-consuming,
as the rivets generally have to be hardened, tempered and coated after forming,
in order to achieve an adequate strength and corrosion resistance. A promising
approach to improve the efficiency of the rivet manufacturing is the use of high-strength
high nitrogen steel as rivet material because these additional process steps would
not be necessary anymore. As a result of the comparatively high nitrogen content,
such steels have various beneficial properties like higher strength, good ductility
and improved corrosion resistance. By cold bulk forming of high nitrogen steels
high-strength parts can be manufactured due to the strengthening which is caused
by the high strain hardening. However, high tool loads thereby have to be expected
and are a major challenge during the production process. Consequently, there is
a need for appropriate forming strategies. This paper presents key aspects concerning
the process design for the manufacturing of semi-tubular self-piercing rivets
made of high-strength steel. The aim is to produce the rivets in several forming
stages without intermediate heat treatment between the single stages. Due to the
high strain hardening of the material, a two stage forming concept will be investigated.
Cup-backward extrusion is chosen as the first process step in order to form the
rivet shank without forming the rivet foot. Thus, the strain hardening effects
in the area of the rivet foot are minimized and the tool loads during the following
process step can be reduced. During the second and final forming stage the detailed
geometry of the rivet foot and the rivet head is formed. In this context, the
effect of different variations, for example concerning the final geometry of the
rivet foot, on the tool load is investigated using multistage numerical analysis.
Furthermore, the influence of the process temperature on occurring stresses is
analysed. Based on the results of the investigations, an adequate forming strategy
and a tool concept for the manufacturing of semi-tubular self-piercing rivets
made of high-strength steel are presented.

text: As a result of lightweight design, increased use is being made of high-strength
steel and aluminium in car bodies. Self-piercing riveting is an established technique
for joining these materials. The dissimilar properties of the two materials have
led to a number of different rivet geometries in the past. Each rivet geometry
fulfils the requirements of the materials within a limited range. In the present
investigation, an improved rivet geometry is developed, which permits the reliable
joining of two material combinations that could only be joined by two different
rivet geometries up until now. Material combination 1 consists of high-strength
steel on both sides, while material combination 2 comprises aluminium on the punch
side and high-strength steel on the die side. The material flow and the stress
and strain conditions prevailing during the joining process are analysed by means
of numerical simulation. The rivet geometry is then improved step-by-step on the
basis of this analysis. Finally, the improved rivet geometry is manufactured and
the findings of the investigation are verified in experimental joining tests.
